Application server autonomous access (ASAA) server and wireless transmitting/receiving unit communicating with ASAA server

Technical field

This creation is related to network architecture and wireless network architecture. In particular, this creation is related to the use of multiplexed network systems for communication services.

Background technique

The current wireless technology allows a user to be called due to a call received and a call sent to a wireless transmitting/receiving unit of a user in a single wireless access network area. However, in the current technology, there is no support for such calls and paging routes between different access technologies (for example, 2G/3G wireless network, CDMA 2000 network, WLAN/Bluetooth network). Therefore, it is hoped that there can be a mechanism by which "application-level" calls and paging routes can cross different access networks, so as to allow a WTRU to roam between such networks, so as not to miss any connections through the current connection. Paging to access the network.

Creation content

The first specific embodiment is an Application Server Autonomous Access (ASAA) server. A network service identifier circuit is used to identify network services available to a wireless transmitting/receiving unit (hereinafter referred to as WTRU). A receiver circuit is used to receive a request to communicate with the WTRU. A network identifier circuit is used to identify the access network, and through the access network, the WTRU can communicate and determine a better access network. A pager mechanism is used to send calls to the WTRU through the identified wireless access network. A route device is used to determine the communication route sent to or from the WTRU through a better access network.

A second embodiment is an embodiment in which a WTRU and an ASAA server work together. A circuit establishes a radio frequency (hereinafter referred to as RF) to connect to one of multiple access networks. A data processing circuit is used to process data sent to or from the access network. An ASAA associated circuit is used to provide a communication link with an ASAA server.

Detailed ways

As used herein, the technical term of the "wireless transmit/receive unit" (WTRU) includes, but is not limited to, a user equipment, a mobile station, a fixed or mobile telephone subscriber unit, a pager, or any other device that can be used in a wireless environment The type of device to be operated under. The technical term "base station" includes, but is not limited to, a Node B, an address controller, an access point, or any other type of interface device in a wireless environment. An "access point" (hereinafter referred to as AP) refers to a station or device that provides wireless access to devices to establish a wireless connection with a local area network and establish a wireless local area network connection (hereinafter referred to as WLAN ). If the AP is a fixed device on a wireless local area network, the AP is a station that transmits and receives data. The AP allows a WTRU to connect to a network, where the WLAN itself has a connection to the network.

According to this creation, the command, execution, user interface, and call and paging routes can cross different access networks to allow a user's wireless transmit/receive unit (WTRU) to roam between these networks without missing ground Receive calls through the currently connected access network. These services are regarded as "application-level" functions, where they are not necessarily related to a specific air interface. A system architecture allows calling or paging routes across different types of wireless and wired access networks. The system architecture is defined to be adaptable to the Application Server Autonomous Access (ASAA) protocol and the protocol allows the call and paging across different types of networks. According to this creation, such services will come from such servers, or "ASAA servers". Separate networks will provide different ranges of wireless access, such as residential areas, business areas, popular areas, and similar areas. Users can use different wireless access networks for access services, but they can also use fixed services provided by "ASAA Operators". In other words, the phone user may have a predetermined ASAA operator, where the user pays the access operator for the access fee. The processing within the access network is achieved by different access methods currently being processed by the network.

ASAA provides a consistent and non-missing service to the user, especially when the user roams between different access networks. This architecture allows users to receive incoming calls when roaming between different networks. It also allows the user to receive a consistent service, especially when he/she is accessing the Internet. The ASAA server provides this combination of services.

When a WTRU roams between these networks, the WTRU can receive calls through the currently connected access network without loss. In this architecture and system concept, when the WTRU moves between different access networks, a server provides a fixed point of interconnection to connect to an external voice/data network. An example of such an external voice/data network is a public switched telephone network (hereinafter referred to as PSTN) and a public data network (hereinafter referred to as PDN). The ASAA architecture allows communication services at the application level to be provided to a server that has nothing to do with wireless connection services and across different connection networks, and further allows the transmission of application services between different connection networks. The ASAA architecture further allows services to be provided in a continuous manner to different WTRUs during the same communication period.

The ASAA architecture provides the integration of network architectures so that different technical networks can communicate with each other through a wireless/transmit-receive unit (WTRU). For example, these different networks include: The Third Generation Partnership Project (3GPP) Wideband Code Division Multiple Access (W-CDMA) communication system, which is an implementation of the Global Mobile Telecommunications System (hereinafter referred to as UMTS) Systems; other wide-area public land mobile network (hereinafter referred to as PLMN) systems; private networks, such as those implemented through WLAN systems, IEEE "802" systems, and Bluetooth systems; private small studio (SOHO) networks The network is also implemented through the WLAN system, the IEEE "802" system and the Bluetooth system; and the telephone line-based network system.

According to this creation, the ASAA server combines area, service, and route information to phone users. The ASAA server determines the call route and advances the service to the user's appropriate service network based on the profile of the strategy. The strategy profile includes areas, technical network compatibility, behavioral factors, cost benchmarks, and other criteria related to the call route. The ASAA server allows the use of technology-based Internet protocols (hereinafter referred to as IP), such as the Session Initiation Protocol (hereinafter referred to as SIP), which supports the integration of technologies. The use of these standard protocols provides the ability to implement ASAA architecture and services based on standard protocols, such as IP and TCP/IP.

In an ASAA application, a WTRU configured according to this creation will attempt to access the ASAA application server. This caused a registration action. The normal transfer of zone information between the WTRU and the ASAA server provides the ASAA server connection data. The ASAA agreement provides a combination of area, service, and route information to enable ASAA users to span multiple technical networks. This allows the use of a shared IP infrastructure solution between different technology networks without loss of mobility.

An ASAA server provides identification of network services available to the WTRU. When a call for a WTRU enters the ASAA server, the ASAA server sends a call signal to the WTRU, through which all WTRUs may preferentially access the network. The call mechanism described is based on IP and operates at the application layer. The WTRU receives the call request through the currently connected access network of the WTRU, and sends a call response back to the ASAA server through the connected access network. The call response informs the ASAA server of the identification of the access network to which the WTRU is currently connected. Therefore, the ASAA server then specifies a route for the woven incoming call through the access network. The ASAA server can provide a constant supplementary service to the WTRU, no matter what kind of access network the WTRU is connected to. The call mechanism has an end-to-end application level, preferably based on IP.

This allows for loss-free mobility, a loss-free transmission method, and the ability to provide services to switch to different networks to ensure that a particular network can support at least the communication of the service. This allows the user's profile to be applied to multiple networks, and allows the user to select services based on a single profile. Therefore, if a particular service is free or has been provided at a steady rate, the user can decide in advance to only receive services based on these standard items. Similarly, the use of the ASAA server allows the integration of services, such as billing.

Figure 1 shows a schematic illustration of a network environment 11, which presents a diagram of the relationship between an ASAA server 12, network service entities, and a WTRU created according to the present invention. As shown in the figure, in addition to the network environment 11 and the ASAA server 12, there is also a public switched telephone network or public data network (PSTN/PDN) 14 and a public land mobile network (PLMN) 15 .

The PLMN 15 includes multiple local area networks 21-25, such as an entertainment store network 21 at an airport location, an airport lounge network 22, an office network 23, a coffee shop 24 that provides WLAN services, and Home network 25 etc. The PLMN 15 also includes a large area mobile service 26, such as a mobile service including a 3G device 27 and a SIP device 28.

The large-area mobile service 26 provides communication services through WLAN, BT, and UMTS. The local area network 21-25 and the large area mobile service 26 form an access network. Communication via LANs 21-25 is typically based on IP protocol, SIP protocol or other packet exchange protocols. Traditionally, such communications use a shared channel and specify the bandwidth according to demand.

Multiple ASAA application services 41-43 are provided in different locations, including WLAN 23, home network 25, and large area mobile service 26. This allows application services to be provided through their respective access networks 23, 25, and 26, but access through other access networks is also allowed.

The WTRU 13 shown in the figure can communicate with one of the access networks 21-26. The ASAA server 12 can establish a communication link with the WTRU 13 by directly or indirectly connecting to one of the networks 21-26, wherein these networks establish a communication link with the WTRU. In this architecture, the services described come from the ASAA server. The access network provides access to the user, so calls and other interactions between the user and the ASAA server determine the routing route through the access network connected to the user. This enables the ASAA server 12 to operate as a service platform in order to deliver services to the user through one of these different access networks 21-26.

The WTRU 13 can communicate through different services, such as different services provided by the WLAN 23, but once connected, the ASAA server 12 can provide management functions to directly provide services through the ASAA server 12, or The request for such a service can be from a variety of different access networks 21-26 to point to the path to the access network connected to the WTRU 13. In this architecture, such services are provided by the ASAA server 12. The access network provides access to the WTRU 13, so calls and other interactions between the WTRU 13 and the ASAA server 12 are scheduled to travel through the access network 21-26 to the WTRU 13 Linked access network.

The ASAA server 12 also includes server function modules 61 and 62. The server function modules 61, 62 provide management functions for operating the ASAA server 12 and maintaining the database of the location of the WTRU 13 and the availability of the access networks 21 to 26. The server function modules 61 and 62 also provide application functions that can be executed by the WTRU through the access network connections.

The ASAA server 12 provides a fixed interface to the PSTN/PDN 14 to receive/transmit call intentions and route incoming calls to the WTRU's access network based on the WTRU's location. In the incoming call, the ASAA server 12 calls all possible service access networks that are prioritized to be allocated to the WTRU 13. The WTRU 13 responds with a call response and routes through the currently connected service network. The ASAA server 12 then forwards the incoming call through a service network to which the WTRU 13 is currently connected.

The WTRU 13 can also "force route" the incoming call through a specific service access network by appropriately configuring the ASAA server 12, and by identifying the service access network to route the call through its designated . By embodying the access network, the WTRU 13 can control which service is used.

This architecture relaxes the traditional cellular call and paging routing mechanism so that it can work across a range of access networks. In a specific embodiment, an IP-based application-level call mechanism operates across different access networks to help locate the WTRU 13 used.

A preferred embodiment includes providing a joint interface through the ASAA server to allow PSTN/PDN 14 to receive the call, and the ASAA server 12 allows PSTN/PDN 14 to receive the call through a single stop point. From the user's point of view, such an effect is that the wireless connection service is provided by a specific wireless connection, and the wireless connection is the wireless connection of each of the access networks 21 to 26. This kind of service installation means that the user interface can be the local area network 21-26 or the ASAA server 12. Therefore, as shown by the dotted line 69 in the figure, the system transfers the network management rights of the user service and the service devices "uploaded" by the user from the respective access networks to the ASAA server 12. From the user's point of view, the ASAA server 12 then becomes a virtual server. The wireless connection network service is provided by accessing the networks 21-26 separately, and the network service provided to the user is provided by the ASAA server 12 instead of wireless connection. If the operator of the ASAA server 12 can obtain the wireless service as provided by the respective access networks 21-26, the user can let the service identify the operator with the ASAA server 12.

This architecture supports the mobility of the WTRU 13 across multiple access networks and assists in positioning the WTRU 13 without loss. The use of the ASAA server 12 allows configured users to route calls through a given access network. This also provides a constant set of supplementary services and emphasizes the characteristics of spanning multiple access networks, so that users can continue to operate even after network changes. Such an architecture may also provide a uniform mechanism configuration to provide the WTRU 13 advancing services across multiple priority access networks.

The ASAA server 12 provides a management function that considers routing services between the different access networks 12 to 26, and the function it plays enables it to maintain a shared location of the user profile. The user can decide what kind of service to use to determine what physical environment the user is in. For example, these control parameters include processing, service type selection, service price and price structure selection, network owner selection, notification of link network availability, user-determined small amount of service (QOS), And the service bandwidth required for a specific function. The selection function of the call processing profile can include voice mail, call selection management, and "challenge" response. In the same way, the ASAA server 12 can also provide voice mail and other data management services.

Figure 2 shows the relationship between a WTRU 81, an ASAA server 83, and access networks 91-95. The WTRU includes a circuit for establishing an RF link 87 and a circuit for processing data 88, although some of these functions are integrated into the circuit function. The WTRU 81 establishes a communication link with the ASAA server 83, but the service link is usually between the WTRU 81 and the service network 91-95. The communication service can communicate wirelessly with the WTRU 81 through the ASAA server 83 or through the service network 91-95. Alternatively, the communication service can also be from a service network to a service network that establishes a wireless connection with the WTRU 81 without going through the ASAA server 83. Under the communication managed by the ASAA server, the communication that does not pass through the ASAA server 83 or does not originate from the ASAA server may still be managed by the ASAA server 83. Because the processing circuit 88 processes data regardless of the source of the data, it is actually connected to a specific service network 91-95 and can be transmitted to the user.

Figure 3 shows the functional flow of a preferred embodiment of the present creation, Figure 1 00. The association between an ASAA and a WTRU is established through the connection between the WTRU and an access network (step 111) to provide a communication with the ASAA server (step 112), thereby notifying the WTRU of available servers ( Step 113). When the ASAA server is not required to notify the available servers (step 113), this facilitates the location where the WTRU should receive the request for communication with the WTRU by the ASAA server.

The WTRU initiates a service request by communicating the request to the ASAA server through the access network (step 121). The ASAA server then responds by determining the preferred access network for establishing the communication (step 126). The preferred access network is determined based on the database input of the preferred service (step 127), the service price and other changes (step 128), and the response from the available access network connected to the WTRU (step 129). Then the ASAA provides the service by providing the service through the ASAA server (step 131) or by communicating through the ASAA server (step 132). Alternatively, the service link can be operated directly through the access network (step 135).

In response to an external communication request, the ASAA server sends a call request to the WTRU (step 141), where the call request is connected to one or more access networks (step 142). In the case where the ASAA server has identified the location of the WTRU (step 144), the call request may be restricted to communications passing through an access network or a subgroup of access network restrictions. A communication link is established between the WTRU and the access network (step 146), and between the access network and the ASAA server (step 147).

For the ASAA server, it is impossible to communicate with the WTRU without informing the priority of the available WTRU (step 113). Figure 4 shows a preferred embodiment according to the present invention, in which the ASAA server does not first establish a connection with a WTRU to initiate the communication with the functional step flow Figure 2 00. The WTRU connects to an access network (step 211) and provides a communication request to the ASAA server through the access network (step 223). Subsequently, the ASAA server uses the communication to determine an initial connection with the WTRU, which is established by the WTRU in the communication request.

Subsequently, the ASAA server responds by determining a better access network for establishing the communication (step 226). The preferred access network is determined based on the database input of the preferred service, service prices, and other changes, as well as the response from the available access network connected to the WTRU. Then the ASAA provides the service by providing the service through the ASAA server (step 231) or by communicating through the ASAA server (step 232). Alternatively, the service link can be operated directly through the access network (step 235).

In response to the external communication request, the ASAA server sends a call request to the WTRU (step 241), where the call request is connected to one or more access networks (step 242). In the case where the ASAA server has identified the location of the WTRU (step 244), the call request may be restricted to communications passing through an access network or a subgroup of access network restrictions. A communication link is established between the WTRU and the access network (step 246), and between the access network and the ASAA server (step 247).

Although the features and components of this creation are described in specific combinations in the preferred embodiment, each feature or element can be used alone (without matching other features and components in the preferred embodiment) or It is used in different combinations with or without features or components according to the creation.
