Method, device and system for processing group message

TECHNICAL FIELD

0001The embodiments of the invention relate to the field of communication technologies, and particularly, to a method, a device and a system for processing a group message.

BACKGROUND

0002With the widespread usage of the smart user equipment (UE) (e.g., the mobile phone), applications on the UE are increasingly richer. Application services, such as microblog and social network instant messaging (e.g., Twitter, Facebook, QQ and MSN) are more and more popular in the users.

0003With regard to application services such as Twitter, Facebook, QQ and Msn, users corresponding to the UEs are usually managed on a group basis in corresponding Application Server (AS) according to the users' requirement. For example, the same message is usually required to be sent to all users in one group. However, the UEs in the same group in the AS will not be uniformly managed at the network side. For example, with regard to services such as QQ and Msn, a message is usually sent to each UE in the group through the Gateway GPRS Support Node (GGSN) and the Serving GPRS Support Node (SGSN) in the Core Network (CN), and the Radio Network Controller (RNC) and the NodeB (NB) in the Universal Mobile Telecommunication System Terrestrial Radio Access Network (UTRAN), respectively. With regard to services such as Twitter and Facebook, corresponding AS adopts the instant pushing mode, i.e., generally pushing a message to each UE in the group through the GGSN and the SGSN in the CN, and the RNC and the NB in the UTRAN, respectively.

0004During the implementation of the present invention, the inventor finds that the prior art at least has the following problem: in the prior art, when the AS sends a message to the UEs in the same group, the message needs to be sent to each UE in the group through the CN and the UTRAN; thus in the prior art, the AS is low efficient in sending a message to each UE in the same group.

SUMMARY

0009The embodiments of the present invention provide a method, device and system for processing a group message, so as to overcome the defect in the prior art that the AS is low efficient in sending a message to each UE in the same group.

0010The present invention is defined in the independent claims. Preferred embodiments are defined in the dependent claims.

0011Through the technical solution of the embodiment, a group message or a group message notification may be sent to the UEs in a group of the AS on a group basis when the group has an updated message. In addition, the group message or the group message notification only needs to be sent to the UEs in the same group for one time, rather than being sent to different UEs respectively for multiple times in the prior art, thus the efficiency for the AS to send a message to each UE in the group can be effectively improved.

DESCRIPTION OF EMBODIMENTS

0013In order that the objects, technical solutions and advantages of the present invention are clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described as follows with reference to the drawings. Obviously, those described herein are just parts of the embodiments of the present invention rather than all the embodiments. Based on the embodiments of the present invention, any other embodiment obtained by a person skilled in the art without paying any creative effort shall fall within the protection scope of the present invention.

0014The technical solutions of the invention can be applied to various communication systems, such as Global System for Mobile communications (GSM), Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access Wireless (WCDMA), General Packet Radio Service (GPRS) and Long Term Evolution (LTE).

0015In addition, respective aspects will be described herein in conjunction with the user equipment (UE) and/or the base station. The UE may refer to a device that provides the user with voices and/or data connectivity. The UE may be connected to a computing device such as laptop computer or desktop computer, or other communication device such as a self-contained device like the Personal Digital Assistant (PDA). The wireless terminal may also be called as system, subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device or user equipment. The UE may be subscriber station, wireless device, cellular phone, Personal Communication Service (PCS) phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device having the wireless connection function, or other processing device connected to the wireless modem.

0016The base station (e.g., access point) may refer to a device in an access network which communicates with the wireless terminal through one or more sectors at the air interface. The base station may be used to convert the received air frame and the Internet Protocol (IP) packet into each other, as a router between the wireless terminal and the rest part of the access network, wherein the rest part of the access network may include an IP network. The base station may further coordinate an attribute management of the air interface. For example, the base station may be a Base Transceiver Station (BTS) in the GSM or CDMA, a NodeB in the WCDMA, or an evolutional NodeB (eNB or e-NodeB) in the LTE, and it is not limited in the present invention.

0017Respective aspects will be described in the form of a system that may include one or more devices, components, modules or units. It shall be understood or appreciated that various systems may include additional devices, components, modules and/or units, and/or not include all those devices, components, modules and units discussed with reference to the drawings. In another aspect of the present invention, combinations of the above measures may be employed.

0018In addition, the term "and/or" herein is just an association relation that describes the associated objects, and it indicates that there may be three relations. For example, A and/or B may indicate the following three conditions: A is existed separately, A and B are existed at the same time, and B is existed separately. In addition, the character "/" generally indicates that the relation between the associated objects is "or".

0019<figref idref="f0001">Fig. 1</figref> is a flowchart of a group managing method provided by an embodiment of the present invention. The executive subject of the group managing method of the embodiment is a PUSH server, which may be a logical function entity, an individual entity or an individual physical entity. In the practical applications, the PUSH server may be provided at the network side together with the Gateway GPRS Support Node (GGSN), or independent from the GGSN and connected thereto. As illustrated in <figref idref="f0001">Fig. 1</figref>, the group managing method of the embodiment may include the following contents.

0020100: allocating a first group identifier to a user group in an Application Server (AS).

0021Specifically, each user group in the AS is allocated with a group identifier, and different user groups in the AS are allocated with different group identifiers. For example, each user group in the AS is allocated with a first group identifier, so that each user group in the AS has a first group identifier that uniquely identifies the group.

0022101: acquiring, according to a first identifier of a user joining the group corresponding to the first group identifier, parameter information of the user.

0023In which, the parameter information of the user includes a second identifier of the user, location information of a UE corresponding to the user, and an identifier indicating whether the user enables reception of PUSH notification. For example, the first and second identifiers may be the same as or different from each other. For example, the first identifier herein may be a private IP of the user, a Temporary Mobile Subscriber Identity (TMSI), a Packet-TMSI (P-TMSI) or a user name, wherein the private IP may be an IP of the user in a Public Land Mobile-communication Network (PLMN). The second identifier may be a TMSI, a P-TMSI or an International Mobile Subscriber Identity (IMSI). When the first identifier is a private IP or a user name, corresponding second identifier may be an IMSI of the user, and if the user has been activated in a core network, corresponding second identifier may also be a TMSI or a P-TMSI. Similarly, when the first identifier is a TMSI or a P-TMSI, corresponding second identifier may be an IMSI of the user, and if the user has been activated in the core network, corresponding second identifier may also be a TMSI or a P-TMSI. In which, the IMSI of the user is an identification code for uniquely identifying the user in the mobile network.

0024In the embodiment, the identifier indicating whether the user enables reception of PUSH notification means that when there is an updated group message in the group, the PUSH server sends the group message to the user in the group through a PUSH mechanism. When the reception of PUSH notification is enabled, the user can receive the group message of itself in the group in the AS forwarded by the PUSH server, and when the reception of PUSH notification is disenabled, the user cannot receive the group message of itself in the group in the AS forwarded by the PUSH server.

0025102: a PUSH server establishes a group-based transmission bearer with a core network node.

0026In which, the core network node is a GGSN or a Serving GPRS Support Node (SGSN). For example, when the PUSH server is integrated with the GGSN, it can be understood that the PUSH server integrates all the functions of the GGSN, and then the core network node is regarded as the SGSN. When the PUSH server and the GGSN are provided separately, the core network node may be deemed as the SGSN.

0027103: the PUSH server creates a group context corresponding to the first group identifier, wherein the group context includes the parameter information of the user in the group and information of the transmission bearer.

0028For example, in the embodiment, 100 specifically may represent a first group identifier pre-allocated to a group in the AS before the PUSH server creates any group in the AS, a first group identifier allocated by the PUSH server to a group created in the AS when a first user joins the group, or a first group identifier allocated by the PUSH server to a group created in the AS when the AS sends to the PUSH server a request for allocating a group identifier to the group when the number of users enabling the reception of PUSH notification exceeds a predetermined threshold. For example, the first group identifier may include two parts, such as an identifier (e.g., ID) and a group identifier (group ID) of the Public Land Mobile-communication Network (PLMN). In which, the group identifier may be an identifier corresponding to the group in the AS, and it may be called as a second group identifier so as to be distinguished from the first group identifier in the PUSH server. The first group identifier is a unique identifier used in the mobile network and transmitted at the air interface, and the second group identifier is an identifier used by the UE in the AS.

0029In the embodiment, the location information of the UE corresponding to the user may be route area information or location area information of the UE, e.g., the address or identifier of the GGSN and the SGSN corresponding to the UE, provided that the UE corresponding to the user can be accurately located through the route area information or the location area information.

0030The managing method based on group PUSH mechanism in the embodiment allocates a first group identifier to a group in an AS; acquires, according to a first identifier of a user joining the group, parameter information of the user, wherein the parameter information of the user includes a second identifier of the user, location information of a UE corresponding to the user, and an identifier indicating whether the user enables reception of PUSH notification; establishes a group-based transmission bearer with a GGSN; and creates group context corresponding to the first group identifier, wherein the group context includes parameter information of the user in the group and information of the transmission bearer. Through the technical solution of the embodiment, a uniform management of users in the same group in the AS can be performed according to the created group context, which solves the defect in the prior art that users in the same group cannot be managed uniformly based on groups in the AS and effectively improves the group management efficiency.

0031To be noted, on the basis of the above technical solution, preferably, before step 100 of the embodiment, the group managing method may include setting, in the PUSH server, a predetermined threshold of the number of users enabling reception of PUSH notification. The PUSH server may detect the number of users enabling reception of PUSH notification in the group and compare it with the predetermined threshold, and steps 100 to 103 are performed when it is determined that the number of users enabling reception of PUSH notification in the group reaches the predetermined threshold.

0032In the above solution, the PUSH mechanism will not be started unless the number of users enabling reception of PUSH notification in the group reaches the predetermined threshold, thereby preventing the PUSH mechanism from being started when there are only a small number of users in the group, and avoiding the resource waste.

0033To be noted, following step 100 of the embodiment, the PUSH server may establish a mapping relation between the first group identifier and a second group identifier corresponding to the group in the AS, after allocating the first group identifier to the group in the AS. Thus, for example when the AS sends a joining request of the user to the PUSH server, the joining request may include the IP address of the user and the second group identifier, and the PUSH server can acquire that the user joins the group corresponding to the first group identifier according to the mapping relation between the first group identifier and the second group identifier.

0034Between steps 100 and 101 of the embodiment, the group managing method may further include: the PUSH server detects that the user joins the group in the AS.

0035In which, the PUSH server may specifically detect the joining request of the user for joining the group in the AS in the following three modes: <ol id="ol0001" ol-style=""><li>1) The PUSH server receives from the AS a joining request that carries the second group identifier or the first group identifier corresponding to the group joined by the user, and the IP address of the user. Such type of joining request indicates that the user has successfully joined the group in the AS, and at that time, the joining request sent from the AS to the PUSH server carries the public IP of the user. </li><li>2) The PUSH server directly receives from the UE a joining request that carries the second group identifier or the first group identifier corresponding to the group joined by the user, and the IP address of the user. In that case, the UE may directly communicate with the PUSH server, i.e., it can be deemed that a PUSH Client is provided in the UE. The PUSH Client in the UE may directly communicate with the PUSH server. After the user corresponding to the UE successfully joins the group in the AS, the UE may directly send to the PUSH server a joining request that carries a first identifier of the user, and a second group identifier of the group in the AS joined by the user or a first group identifier corresponding to the second group identifier in the PUSH server. In the embodiment, the identifier of the user may be private IP, TMSI or P-TMSL of the user in the PLMN. </li><li>3) The PUSH server parses a joining request sent from the GGSN to the AS, wherein the joining request carries a second group identifier or a first group identifier corresponding to the group joined by the user, and the IP address of the user.</li></ol>

0036In that case, the identifier of the user may be private IP, TMSI or P-TMSL of the user in the PLMN. Preferably, after parsing the joining request sent from the GGSN to the AS, the PUSH Sever may further parse a joining response sent from the AS to the GGSN, wherein the joining response carries a first identifier of the user and corresponding second group identifier or first group identifier of the group joined by the user, and in that case, the first identifier of the user may be the public IP of the user.

0037Correspondingly, the PUSH server may parse the joining request of the user sent from the GGSN to the AS, and the joining response returned by the AS to the GGSN. After parsing the joining response, the PUSH server may detect and acquire the joining request of the user for joining the group between steps 100 and 101 of the embodiment. Next, the PUSH server may add corresponding parameter information of the user to the group context of the PUSH server according to the joining request of the user.

0038When the GGSN and the PUSH server are provided separately, the core network node includes the GGSN and the SGSN. In that case, in step 101 of the above embodiment, acquiring, according to the first identifier of the user joining the group, the parameter information of the user specifically may include: the PUSH server acquires, according to the first identifier of the user joining the group, the parameter information of the user from the GGSN, the SGSN, a Home Subscriber Server (HSS) or a Home Location Register (HLR).

0039<figref idref="f0002">Fig. 2</figref> is a flowchart of a group managing method provided by another embodiment of the present invention. As illustrated in <figref idref="f0002">Fig. 2</figref>, the group managing method of the embodiment is based on the embodiment corresponding to <figref idref="f0001">Fig. 1</figref>, and the core network node includes the GGSN and the SGSN, wherein step 102 "establishing a group-based transmission bearer with the GGSN" specifically may include the following contents.

00401021: the PUSH server sends indication information to the SGSN through the GGSN, wherein the indication information carries a first identifier of the user and a first group identifier.

0041For example, the indication information is used to indicate the SGSN to notify users in the group to activate group context corresponding to the first group identifier. For example, the indication information indicating the SGSN to notify the users to activate the group context may be sent to the UE corresponding to the user having the first identifier through a Radio Network Controller (RNC) and a NodeB.

00421022: the PUSH server receives from the GGSN a group context activation request that includes a first communication port allocated by the GGSN to the group.

0043For example, the group context activation request is sent from the GGSN upon a created group context activation request sent from the SGSN, the created group context activation request being sent from the SGSN upon a group context activation request sent from the UE.

00441023: the PUSH server allocates to the group a second communication port for communicating with the GGSN.

0045For example, the second communication port allocated by the PUSH server to the group for communicating with the GGSN is corresponding to the first communication port, so as to subsequently transmit a group message corresponding to the first group identifier between the PUSH server and the GGSN, according to the second communication port and the first communication port, i.e., to realize a group-based communication between the PUSH server and the GGSN.

00461024: the PUSH server establishes a transmission bearer with the GGSN according to the first and second communication ports.

0047For example, group-based transmission bearers are established between the GGSN and the SGSN, the SGSN and the RNC in addition to the PUSH server and the GGSN.

0048When receiving a notification to activate the group context, the UE sends a group context activation request to the SGSN, then the SGSN creates a group context according to the received group context activation request, and sends a created group context activation request to the GGSN, while the GGSN creates a group context after receiving the created group context activation request sent from the SGSN. Next, the GGSN sends a group context activation request to the PUSH server to notify it that the UE has sent the group context activation request. In which, the request sent from either the SGSN or the GGSN to the parent node carries a communication port allocated to the group for communicating with the parent node. Correspondingly, after receiving the group context activation request, the PUSH server returns a group context activation response to the GGSN, and the GGSN then returns the group context activation response to the SGSN. After receiving the group context activation response, the SGSN establishes a group-based Radio Access Bearer (RAB) with the RNC to subsequently transmit the group message. In addition, the SGSN also returns the group context activation response to the UE to notify it that the group context activation request is successful.

0049In which, each node among the PUSH server, the GGSN, the SGSN and the RNC feeds back to corresponding child node that the group context activation response carries a communication port allocated by the current node to the group for communicating with the child node. In which, the group context activation request initiated by the UE specifically may be a Packet Data Protocol (PDP) group context activation request. Thus the uplink communication port and the downlink communication port can be obtained in the GGSN and the SGSN, so as to establish the transmission bearers between the GGSN and the SGSN in addition to the SGSN and the RNC.

0050Through the above technical solution, the group managing method of the embodiment can establish a group-based transmission bearer between the PUSH server and the GGSN, so as to subsequently transmit corresponding group message of the group between the PUSH server and the GGSN, and send the group message to each UE under the SGSN in the group through the transmission bearer once for all. The technical solution of the embodiment can effectively improve the group management efficiency at the network side.

0051To be noted, after step 103 of the above embodiment, it may further require updating corresponding group context of the group. For example, when a UE joins the group, a UE exits the group, a UE logs out the group, a UE is temporarily powered off, a UE disenables reception of PUSH notification originally enabled, or a UE enables reception of PUSH notification originally disenabled, etc. In that case, the following steps may be included: <ol id="ol0002" ol-style=""><li>a) The PUSH server receives an update request that carries a first identifier of a UE to be updated, wherein the first identifier of the UE may be IP address, P-TMSI, TMSI or user name, meanwhile, a second or first group identifier is also carried.</li><li>b) Updating parameter information of the UE to be updated in the group context corresponding to the first group identifier, according to the update request.</li></ol>

0052When the update request carries the second group identifier, the PUSH server may acquire corresponding first group identifier according to the mapping relation between the first and second group identifiers, and then update the parameter information of the UE to be updated in the group context corresponding to the first group identifier.

0053The update request may be received by the PUSH server from the AS or the GGSN, or directly from the UE corresponding to the user. The update request may be a joining request added by the user, and in that case, the parameter information of the user is correspondingly added to the group context. The update request may also be an exiting request of the user for application logout, group exiting or power off. Correspondingly, the PUSH server deletes the parameter information of the user from the group context, otherwise a state of powered off, application logged out or group exited may be set to represent the user's state. The update request may also modify an identifier indicating whether the user enables reception of PUSH notification, and in that case, corresponding PUSH server modifies the identifier indicating whether the user enables reception of PUSH notification in the group context.

0054The PUSH server may acquire a second identifier of the user according to the first identifier of the user in the update request (refer to the above embodiment for the details), and then update the parameter information of the user to be updated corresponding to the second identifier, in the group context corresponding to the first group identifier.

0055To be noted, when the update request is received by the PUSH server from the AS or the GGSN, the update request may also carry the second identifier of the UE.

0056In which, if the PUSH server deletes the parameter information of the user corresponding to the UE, the process of application logout, group exiting or power off of the user corresponding to the UE may also be deemed as a deactivation process of the group. In correspondence to the activation process, the deactivation process of the group context may be triggered through an interaction between the PUSH server and the AS or the UE corresponding to the user after the UE interacts with the AS. If related information of the user is not to be deleted, a state of powered off, application logged out or group exited may be set to represent the user's state, and this process may be deemed as the update process of the group. The update process of the group context may be triggered through an interaction between the PUSH server and the AS or the UE corresponding to the user after the UE interacts with the AS.

0057When the UE corresponding to the user is powered on or the route area is updated, the UE may send the location information to the Push Server, and the PUSH server may update the location information of the UE corresponding to the user in the group. In that case, it can be deemed that a PUSH Client is provided in the UE, and the UE may send its updated route area information (also referred to as route location information) to the PUSH server in the process of a direct communication with the PUSH server. Or, after the user powers on or the route area is updated, corresponding SGSN sends the route location information of the user, such as SGSN address, SGSN identifier or GGSN address, to the PUSH server when the user corresponding to the UE completes the Attach registration or during or after the route update process. Finally, the PUSH server updates the location information of the UE corresponding to the user in the group context according to the updated route area information of the UE, so as to ensure the accuracy of the information in the group context. To be noted, in the Route Area Update (RAU) process, the new SGSN corresponding to the UE in the idle state notifies the PUSH server to update the location information of the UE in the group context, such as a Route Area Identity (RAI)/Location Area Identity (LAI) of the group to which the UE belongs, so as to determine the cell or RNC of the PUSH group message to be sent subsequently.

0058The UE may be switched in the same SGSN (i.e., Intra-SGSN) between different RNCs (i.e., Inter-RNC). In the locating process of the UE, the SGSN indicates the target RNC after the switching to initiate an establishment of the group PUSH bearer. Meanwhile, the SGSN needs to update the parameter information of the UE and the information of the transmission bearer in the group context established on the SGSN.

0059The UE may be switched between different SGSNs (i.e., Inter-SGSN) and different RNCs (i.e., Inter-RNC). In that case, a source SGSN transmits group context information related to the UE in the group context to a target SGSN, and the target SGSN indicates the RNC to initiate an establishment of the group PUSH bearer. After the switching, the target SGSN updates the group bearer with the GGSN, the SGSN notifies the PUSH server, and the PUSH server further updates the RAI of the UE concerned in the group context in the PUSH server. Meanwhile, the target SGSN needs to update the parameter information of the UE and the information of the transmission bearer in the group context established on the target SGSN, so as to adequately ensure the accuracy of information in the group context of each SGSN, and ensure that the PUSH group message is ready to be sent subsequently.

0060In the above embodiments, the technical solutions of the present invention are all described through examples where the user joins a certain group in the AS. But in the practical applications, the user may also simultaneously join multiple groups in the AS according to the implementations of the above embodiments.

0061To be noted, in steps 102 to 104 of the previous embodiment, the transmission bearer between the PUSH server and the GGSN, the GGSN and the SGSN, or the SGSN and the RNC may be established on the following occasions: <ol id="ol0003" ol-style=""><li>1) when the PUSH server determines that a user joins the group;</li><li>2) when the PUSH server determines that the number of users in the group reaches a threshold;</li><li>3) when the PUSH server determines to establish/activate a group;</li><li>4) when the PUSH server receives a PUSH message from the AS; and</li><li>5) when the AS notifies the PUSH server to establish a bearer connection.</li></ol>

0062A transmission bearer based on the application type (e.g., Access Point Name (APN)), a transmission bearer based on a determined group, or a transmission bearer shared by all the groups may be established between the PUSH server and the GGSN, the GGSN and the RNC, or the SGSN and the RNC. When an established transmission bearer needs to be applied to other newly jointed group, it only requires recording the transmission bearer in the group context corresponding to the newly jointed group. Of course, other manners may be used to indicate that the newly established transmission bearer is applicable to all the groups in the practical applications.

0063If the transmission bearer between the PUSH server and the GGSN is established based on all the groups, the Push Server may indicate the first group identifier at the packet head of the downlink packet. When establishing a group Radio Access Bearer (RAB), the SGSN may send to the RNC the first group identifier, the first identifier of the user, or the number of users in one group, and such information may be put in the group context established at each node. A common bearer may be established between the RNC and the NodeB. The NodeB is provided with a notification indication physical channel, a list of bearer group identifiers, a common logical channel of a bearer notifying message, and corresponding common transmission channel and physical channel. In this example, the user joins one group, and when the user simultaneously joins multiple groups, the transmission bearer between the nodes in the embodiment of the present invention may be established in two manners.

0064A) The SGSN and the GGSN/RNC may establish a common transmission bearer for all the groups. The PUSH server indicates the group identifier in the downlink packet, and establishes an IP connection with the GGSN/AS. A connection of GPRS Tunneling Protocol for the user plane (GTP-U) may also be established between the PUSH server and the GGSN. The PUSH server has the IP addresses of the public network and the private network. The format of a data packet that carries the group identifier is defined for the interaction between the AS and the PUSH server. The format of a signaling packet (e.g., signaling indicating to allocate the group identifier, signaling indicating the user to join the group, signaling indicating the user to exit the group, and signaling indicating to stop receiving the PUSH message) is defined for the interaction between the AS and the PUSH server. To be noted, in the practical applications, a permanent correspondence connection may be established between each PUSH server and an AS, e.g., the address of the PUSH server may be configured in the AS. When the network corresponding to an operator includes a plurality of PUSH servers, the mapping relation between the PUSH server and the address of the UE corresponding to the user may be configured in the AS, and the AS may determine a PUSH server corresponding to the address of the UE corresponding to the user according to the mapping relation.

0065A user-level-based GTP-U user plane is established between the SGSN and the GGSN/RNC, including the interaction of Tunnel Endpoint Identifier (TEID) of the address and application type between the user plane nodes. A common RAB bearer group message may be established between the SGSN and the RNC, and a common tunnel may be established for the user plane between the RNC and the GGSN. The RNC and the RNC may also establish a common RAB bearer and corresponding common channel for an application type (QQ, Twitter, etc.), e.g., based on an Access Point Name (APN), or establish a group context and a common transmission bearer tunnel for all the groups.

0066B) The SGSN and the GGSN/RNC may establish a transmission bearer for each group context, respectively, and establish a transmission bearer tunnel and an RAB for each group context, respectively, wherein the GGSN or the SGSN does not need to indicate the group identifier in the downlink packet.

0067In the RNC, through broadcasting, the channel configuration indicated by the group notification may be performed and the channel configuration of the group list may be issued. The channel configuration may be performed when the RNC receives from the SGSN a message for establishing a group RAB or it receives a downlink group message, or the RNC counts that the users of a certain group reaches a predetermined threshold. The RNC calculates the bit indicated by the notification according to the group identifier, and notifies the NodeB of a group identifier list for sending the group message in the notification indication channel and other indication channel of the group. In addition, the RNC also indicates a sending time for the NodeB to send the group message, and the sending time may be a certain timing or period. Thus, the NodeB can send the group message according to the notification of the RNC.

0068When the number of users in the group reaches a certain threshold, the RNC sends a PUSH group message, and when the threshold is not reached, the user may be indicated through a normal broadcasting or a dedicated signaling to stop receiving the PUSH message, and establish a point-to-point bearer to receive the group message.

0069Correspondingly, on the side of the UE corresponding to the user, a group PDP context may be established for all the groups. In that case, it can be deemed that the UE is provided with a client that supports reception of PUSH message, and whether to enable reception of PUSH message may also be configured. For example, the client may interact with the PUSH server or the AS, and configure whether to receive the PUSH message. After activating the group context, the UE monitors the notification indication channel and the notification control channel according to the group identifier of the group context, determines whether there is any group message to be received, and further receives the group message in the notification transmission channel. The notification transmission channel is used to transmit the PUSH message, i.e., the data content to be transmitted. The notification control channel is used to transmit the first group identifier. Of course, the UE may determine whether there is any group message to be received based on other channel, such as the high-speed shared control channel and further receive the group message in the data channel, or directly receive the data packet and determine whether there is any group message to be received based on the data packet of the user plane.

0070In conclusion, after a transmission bearer is established from the UE to the PUSH server, a group context shall be established on each node of the GGSN, the SGSN and the RNC, so as to effectively manage the PUSH server to send a group message to each UE in the group. The group context established on each node includes the parameter information of the UE (referring to the parameter information of the UE in the group context established in the PUSH server), and the information of the transmission bearer through which the path of the PUSH message to be sent can be acquired. Preferably, the RNC and the SGSN may not need to store the IP address of the UE.

0071<figref idref="f0003">Fig. 3</figref> is a flowchart of a managing method based on a group PUSH mechanism provided by still another embodiment of the present invention. As illustrated in <figref idref="f0003">Fig. 3</figref>, the managing method based on the group PUSH mechanism of the embodiment specifically may include the following contents.

0072200: a UE sends a group joining message to an AS.

0073The group joining message includes a first identifier of a user corresponding to the UE and a second group identifier corresponding to a group in the AS to be joined by the user. In addition, when receiving the group joining message, the AS may return a group joining response message to the UE.

0074201: the AS detects whether the number of users joining the group corresponding to the second group identifier and enabling reception of group PUSH message reaches a predetermined threshold; if yes, performing step 202, otherwise performing step 203.

0075202: the AS initiates a PUSH group establishing request to a PUSH server, and then step 204 is to be performed.

0076The PUSH group establishing request includes the second group identifier and the first identifier of the user joining the group.

0077203: when the group in the AS joined by the user has an updated group message, the AS sends a message to the UE corresponding to each user in a normal message sending manner, and please refer to the prior art for the details.

0078204: the PUSH server acquires corresponding first group identifier according to the second group identifier.

0079For example, the PUSH server may acquire the first group identifier corresponding to the second group identifier according to the stored table of mapping relation between the first group identifier and the second group identifier.

0080205: the PUSH server acquires the parameter information of each user joining the group according to the first identifier of the user joining the group.

0081For example, the PUSH server may acquire the parameter information of each user in the group through an interaction with the GGSN, the SGSN, the HSS or the HLR. Please refer to the descriptions of the above related embodiments for the details of the parameter information of the user.

0082206: the PUSH server establishes a group context corresponding to the first group identifier.

0083207: the PUSH server sends indication information for activating the group context of the user to an SGSN through a GGSN.

0084208: the SGSN receives the indication information for activating the group context of the user from the PUSH server.

0085209: the SGSN initiates a paging to the UE corresponding to the user through an RNC and a NodeB, and indicates the UE to activate the group context after a connection is established between the UE and the SGSN.

0086In which, the activated group context of the UE carries the first group identifier corresponding to the group in the AS joined by the user corresponding to the UE.

0087210: the UE initiates a group context activation request, and the SGSN establishes a group context corresponding to the first group identifier and including a second identifier of the user corresponding to the UE.

0088211: the SGSN initiates a created group context activation request to the GGSN according to the received group context activation request sent from the UE.

0089In which, the created group context activation request carries the second identifier of the user, and a port (e.g., a first TEID) allocated by the SGSN to the group for communicating with the GGSN.

0090212: the GGSN establishes a group context including the parameter information of the user according to the received created group context activation request, and initiates a group context activation request carrying a port of the GGSN for communicating with the PUSH server to the PUSH server.

0091After receiving the created group context activation request, the GGSN allocates a second TEID for communicating with the SGSN. Meanwhile, the transmission protocol between the GGSN and the PUSH server shall be further determined, and when it is a GDP-U-based transmission protocol, the GGSN shall allocate to the group a third TEID for communicating with the PUSH server. When the transmission protocol between the GGSN and the PUSH server is an IP protocol, the GGSN shall allocate to the group a first IP port for communicating with the PUSH server.

0092In which, the group context activation request initiated by the GGSN to the PUSH server carries a port of the GGSN for communicating with the PUSH server, e.g., the third TEID or the first IP port.

0093213: after receiving the group context activation request, the PUSH server allocates to the group a port for communicating with the GGSN, and adds the information of the transmission bearer to the group context of the PUSH server.

0094For example, when the transmission protocol between the GGSN and the PUSH server is a GDP-U-based transmission protocol, the PUSH server shall allocate to the group a port for communicating with the GGSN, such as a fourth TEID corresponding to the third TEID. When the transmission protocol between the GGSN and the PUSH server is an IP protocol, the port allocated by the PUSH server to the group for communicating with the GGSN may be a second IP port corresponding to the first IP port. Next, the PUSH server carries the fourth TEID or the second IP port in the group context activation response returned to the GGSN. In that case, the PUSH server may establish a mapping relation between the third and fourth ports, or a mapping relation between the first and second IP ports, so as to record the transmission bearer between the PUSH server and the GGSN of the group in the group context.

0095214: the PUSH server returns a group context activation response to the GGSN.

0096215: the GGSN receives from the PUSH server the group context activation response that carries the port allocated by the PUSH server to the group for communicating with the GGSN, and adds the information of the transmission bearer to the group context.

0097After receiving from the PUSH server the group context activation response, the GGSN may establish a mapping relation between the third and fourth ports, or a mapping relation between the first and second IP ports, so as to record the transmission bearer between the GGSN and the PUSH server of the group in the group context.

0098216: the GGSN returns a group context activation response to the SGSN.

0099217: the SGSN receives from the GGSN the group context activation response that carries a second TEID allocated by the GGSN to the group for communicating with the SGSN, and adds the information of the transmission bearer between the SGSN and the GGSN of the group to the group context of the SGSN.

0100In which, the details of the second TEID have been described in step 212.

0101For example, after receiving the group context activation response, the SGSN can establish a mapping relation between the first and second TEIDs, and record the transmission bearer between the SGSN and the GGSN of the group in the group context

0102218: establishing a group-based RAB connection between the SGSN and the RNC, and adding the information of the group-based transmission bearer between the SGSN and the RNC to the group context of the SGSN.

0103To be noted, the process of establishing a group-based RAB connection between the SGSN and the RNC herein is the same as that of establishing a normal RAB connection between the SGSN and the RNC in the prior art, please refer to related prior art for the details. The difference only lies in that the RAB connection between the SGSN and the RNC in the embodiment is shared based on a group.

0104219: the SGSN sends a group context activation response to the UE, to notify the UE that the group context of each node in a link based on the group is successfully established, and the UE can receive the group message from the PUSH server.

0105The above steps of the embodiment are described through an example where the group context is established on each node for the first time. The group context established on each node of the PUSH server, the GGSN, the SGSN and the RNC includes two parts: the parameter information of the user, and the information of the transmission bearer established for the group message to be transmitted. In that case, based on such network architecture, the PUSH server may manage the users joining the groups in the AS on a group basis, and send the message of a group in the AS to UEs under the group at one time based on the group.

0106In a group of the AS corresponding to the second group identifier, when the location of a user changes, a user joins or exits, or an identifier of a user indicating whether to enable reception of PUSH notification changes, a UE corresponding to the user may initiate an update request to the PUSH server, so as to update related information in the group context. Please refer to the descriptions of related method embodiments for the details, so as to synchronize the group contexts on respective nodes.

0107The technical solution of the embodiment solves the defect in the prior art that the users in the same group cannot be managed uniformly at the network side based on the groups in the AS, performs a uniform management of the users in the same group in the AS, and improves the group management efficiency.

0108<figref idref="f0004">Fig. 4</figref> is a flowchart of a method for processing group message provided by an embodiment of the present invention. As illustrated in <figref idref="f0004">Fig. 4</figref>, the executive subject of the method for processing group message of the embodiment is a PUSH server. As illustrated in <figref idref="f0004">Fig. 4</figref>, the method for processing group message of the embodiment specifically may include the following contents.

0109300: when a group corresponding to a first group identifier has an updated group message, receiving a message corresponding to the first group identifier sent from a Public Data Network (PDN).

0110In which, the message is the updated group message or a group message notification. In the embodiment, the application scenario where the message is the group message notification is that when the group corresponding to the first group identifier has the updated group message, the PDN does not need to directly send the updated group message to the PUSH Server, instead, it sends a notification, i.e., the group message notification, to the PUSH Server, so as to notify the PUSH Server that the group corresponding to the first group identifier has an updated message, and if a UE subsequently wants to view the updated message, the UE shall acquire the updated message by itself. In the embodiment, the PDN is the network where the AS is located except the mobile network where the PUSH Server is currently located. The PDN is provided with various AS. For example, receiving the message corresponding to the first group identifier sent from the PDN specifically may be receiving the message corresponding to the first group identifier sent from the AS in the PDN.

0111301: sending the message corresponding to the first group identifier to a core network node, so that the core network node sends the message to an RNC, which acquires, according to the first group identifier, indication bit and time information for sending the message; sending the first group identifier, the indication bit, the time information and the message to a NodeB, indicating the NodeB to set a bit according to the indication bit, and sending the indication bit, the first group identifier and the message to a UE corresponding to a user in the group corresponding to the first group identifier in a service range of the NodeB, according to the time information.

0112In the embodiment, the core network node is an SGSN, or a GGSN and the SGSN. When the PUSH server is integrated with the GGSN, the core network node herein may be regarded as the SGSN. When the PUSH server and the GGSN are provided separately, the core network node herein includes the GGSN and the SGSN. In that case, "sending a core network node the message corresponding to the first group identifier, so that the core network node sends the message to an RNC" in step 301 specifically may be sending to the GGSN the message corresponding to the first group identifier, so that the GGSN sends the message to the RNC through the SGSN.

0113In the embodiment, the RNC acquires the indication bit and the time information of the sent message according to the first group identifier, wherein the indication bit may be acquired using a calculation method for notifying the indication bit in the Multimedia Broadcast Multicast Services (MBMS), by replacing the identifier of the TMGI with the first group identifier. In addition, other parameters in the calculation method for notifying the indication bit may also be deleted or adjusted in sizes.

0114In the embodiment, the time information may be a time point or a time segment. In which, the RNC may calculate the time information according to the first group identifier and a DRX cycle length received in advance. The DRX cycle length represents discontinuous reception factor parameter. The DRX cycle length may be broadcasted to the UE via the system message in advance, and in practical application, it may be considered to allocate a DRX cycle length to all UEs in one group. The RNC may calculate the time information according to a function: Notification Occasion=F (first group identifier, DRX cycle length). The specific calculation method may employ the UE paging occasion, and corresponding time information is acquired by replacing the IMSI with the first group identifier. Upon demand, sizes of other parameters may be adjusted, or some parameters may be deleted.

0115In the method for processing group message of the embodiment, when a group corresponding to the first group identifier has an updated group message, the PUSH server receives from the PDN a message corresponding to the first group identifier, wherein the message may be the updated group message or a group message notification, then sends the message corresponding to the first group identifier to a core network node, so that the core network node sends the message to an RNC, which acquires, according to the first group identifier, indication bit and time information for sending the group message. The PUSH server sends the first group identifier, the indication bit, the time information and the message to the NodeB, indicates the NodeB to set a bit according to the indication bit, and send the indication bit, the first group identifier and the message to a UE corresponding to a user in the group corresponding to the first group identifier in a service range of the NodeB, according to the time information. Through the technical solution of the embodiment, a group message or a group message notification may be sent to the UEs in a group of the AS on a group basis when the group has an updated message. In addition, the group message or the group message notification only needs to be sent to the UEs in the same group for one time, rather than being sent to different UEs respectively for multiple times in the prior art, thus the efficiency for the AS to send a message to each UE in the group can be effectively improved.

0116<figref idref="f0005">Fig. 5</figref> is a flowchart of a method for processing group message provided by another embodiment of the present invention. As illustrated in <figref idref="f0005">Fig. 5</figref>, the executive subject of the method for processing group message of the embodiment is an RNC. As illustrated in <figref idref="f0005">Fig. 5</figref>, the method for processing group message of the embodiment specifically may include the following contents.

0117400: when a group corresponding to a first group identifier has an updated group message, receiving a message corresponding to the first group identifier sent from a core network node.

0118The message is the updated group message in the group corresponding to the first group identifier or a group message notification. In the embodiment, the core network node is the SGSN.

0119401: acquiring, according to the first group identifier, indication bit and time information for sending the message.

0120402: sending to a NodeB the first group identifier, the indication bit, the time information and the message, indicating the NodeB to set indication information in the indication bit, and to send the indication information set in the indication bit, the first group identifier and the message to a UE corresponding to a user in the group corresponding to the first group identifier in a service range of the NodeB, according to the time information.

0121In the method for processing group message of the embodiment, when a group corresponding to the first group identifier has an updated group message, a message corresponding to the first group identifier is received from a core network node such as the SGSN; indication bit and time information for sending the group message is acquired according to the first group identifier; the first group identifier, the indication bit, the time information and the message are sent to the NodeB, which is indicated to set indication information in the indication bit, and the indication information set in the indication bit, the first group identifier and the message are sent to a UE corresponding to a user in the group corresponding to the first group identifier in a service range of the NodeB, according to the time information. Through the technical solution of the embodiment, a group message may be sent to the UEs in a group on a group basis, so that it is received by each UE in the group. As compared with the prior art, through the technical solution of the embodiment, the UEs in the same group only requires one sending at the network side, thus the efficiency for transmitting the group message can be effectively improved.

0122To be noted, when the PUSH Server and the GGSN are provided separately, the transmission bearer between the PUSH Server and the GGSN may be established based on one certain group or all the groups. For the specific way of establishing the transmission bearer, please refer to the description of related embodiment of the group managing method, and herein is omitted.

0123When the transmission bearer between the PUSH Server and the GGSN is established based on one certain group, "sending the message corresponding to the first group identifier to a core network node" in step 301 specifically may be sending, by the PUSH Server, the message corresponding to the first group identifier to the GGSN through a transmission bearer between the PUSH Server and the GGSN established for the group corresponding to the first group identifier.

0124When the transmission bearer between the PUSH Server and the GGSN is established based on all the groups, "sending the message corresponding to the first group identifier to a core network node" in step 301 specifically may be sending, by the PUSH Server, a message carrying the first group identifier to the GGSN through a transmission bearer between the PUSH Server and the GGSN established for all the groups.

0125Similarly, in the embodiment, a transmission bearer between the GGSN and the SGSN may also be established based on all the groups or one certain group in the same way. Moreover, in the same way, the GGSN sends a message carrying the first group identifier to the SGSN through the transmission bearer established based on all the groups, or the GGSN sends a message carrying the certain group to the SGSN through the transmission bearer established based on one certain group.

0126Similarly, a message may be sent between the RNC and the SGSN in the same way. A transmission bearer between the RNC and the SGSN may also be established based on all the groups or one certain group in the same way. Moreover, in the same way, the SGSN sends a message carrying the first group identifier to the RNC through the transmission bearer established based on all the groups, or the SGSN sends a message corresponding to the first group identifier to the RNC through the transmission bearer established based on one certain group.

As illustrated in <figref idref="f0008">Fig. 8</figref>, the method for processing group message of the embodiment specifically may include the following contents.

0140700: when a group content corresponding to a first group identifier is updated, an AS sends a group message notification to a PUSH Server.

0141701: the PUSH Server sends the group message notification corresponding to the first group identifier to a GGSN, according to a transmission bearer in a group context of the PUSH Server.

0142In which, when the transmission bearer between the PUSH Server and the GGSN is established based on all the groups, the PUSH Server may indicate the first group identifier in a downlink data packet sent, such as an IP packet head or an IP load.

0143702: the GGSN sends the group message notification corresponding to the first group identifier to an SGSN according to a transmission bearer in a group context of the GGSN.

0146Similarly, when the transmission bearer between the SGSN and the RNC is established based on all the groups, the SGSN may indicate the first group identifier by adding a field into a GTP-U head or an IP head.

0147704: the RNC acquires indication bit and time information according to the first group identifier.

0149706: the NodeB indicates, in the indication bit in the notification indication channel, that the UE needs to receive the group message notification, sends the notification indication channel according to the time information; and sends in a notification control channel the first group identifier and the configuration parameters of an notification transmission channel to the UE.

0150707: the UE calculates the indication bit according to the first group identifier; detects, in the notification indication channel, the received indication information in the indication bit; and determines the group message is to be received according to the indication information in the indication bit.

0151708: the UE detects, in the notification control channel, the received first group identifier, and determines that the first group identifier is corresponding to the group in the AS joined by the UE.

0152For example, the UE calculates the indication bit in the same method as the RNC.

0153709: the UE configures the notification transmission channel according to the configuration parameters of the notification transmission channel received in the notification control channel, and receives the group message notification in the notification transmission channel.

0156For the details of steps 710-711, please refer to the prior art, and herein are omitted.

0157To be noted, step 710 of the embodiment is performed for the UE in an idle state. When the UE is in a URA-PCH state, after detecting the received indication information in the indication bit in the notification indication channel and receiving the predefined group identifier in the notification control channel, the UE initiates a service request to the RNC to establish a point-to-point bearer, and sends a request for group message to the RNC through the NodeB. When the UE is in a CELL-PCH or CELL-forward access channel state, after detecting the received indication information in the indication bit in the notification indication channel and receiving the predefined group identifier in the notification control channel, if the point-to-point bearer between the UE and the RNC has been established, the UE sends a request for group message to the AS in the established bearer.
