TECHNICAL FIELD OF THE INVENTION
The present invention relates to communications in a wireless communication system, and more particularly - to the unification of communication signals that are generated by the access terminal.
BACKGROUND
In the development of wireless communication systems are several different generations, which include the first generation (1G) analog wireless telephone communication, second generation (2G) digital wireless phone service (including an interim 2.5G and 2.75G networks) and a third-generation (3G) wireless communication, high-speed data / Internet service. Currently used many different types of wireless communication systems that include cellular communication systems and personal communication service (PCS). Examples of known cellular systems include the cellular analog advanced mobile communication system (AMPS) and of a digital cellular communication based on code division multiple access (CDMA), multiple access, frequency division (FDMA), multiple access with time division (TDMA ), global system for mobile communications (GSM) - a kind of TDMA, and newer hybrid digital communication systems using both TDMA and CDMA technologies.
The method for providing CDMA mobile communication has been standardized in the United States Telecommunications Industry Association / Electronic Industries Association standard TIA / EIA / IS-95-A, entitled "Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum Cellular System", said herein as IS-95. Combined AMPS and CDMA systems are described in the standard TIA / EIA IS-98. Other communications systems are described in the IMT-2000 / UM, or International mobile communication system 2000 / universal mobile telecommunications system, these standards covering what are called wideband CDMA (WCDMA), CDMA2000 (e.g., standards of CDMA2000 1xEV-DO) or TD-SCDMA .
In wireless communication systems, mobile stations, phones or access terminals (AT) receive signals from fixed set of base stations (also known as cell sites or cells) that support communication links or provide service within particular geographic regions adjacent to the base station or surrounding their. Base stations provide entry points to an access network (AN) / radio access network (RAN), which is generally a packet data network using standard protocols developed by the Engineering Group on the development of Internet (IETF), which support the processes of differentiation of traffic on the basis of quality requirements service (QoS). Thus, the base stations generally interact with the AP over a radio interface and with diabetes - the data packets through the Internet Protocol (IP).
In wireless communication capabilities Push-to-talk («push to talk») (PTT) are becoming popular among consumers services and consumers. PTT can support the service "distribution" of voice that works on standard serial wireless infrastructures, such as CDMA, FDMA, TDMA, GSM, etc. The model of "distribution" relationship between endpoints (AP) occurs within virtual groups, wherein the voice of one "speaker" is transmitted to one or more "listeners." A case of performing communication of the type commonly referred to as sending a call or simply a call-PTT. -PTT call is a group, which defines the characteristics of a call. The Group is mainly determined by the Member States and a list of related information, such as group name or group ID.
The group communication or PTT-call, the caller initiates a general access terminal that sends the initial request for the group communication. Conventional systems require multiple connections from a calling party to establish communication links with the infrastructure wireless network / group communication to enable the establishment of the group call. This set of connections can lead to further delay the establishment of a group call and therefore to a deterioration of all usability.

Any embodiment described as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Similarly, the term "embodiments of the invention" does not require that all embodiments of the invention include those described feature, advantage or mode of operation.
Further, many embodiments are described based on the sequence of actions to be performed, e.g., by elements of a computing device. It should be recognized that various actions described may be performed by specific circuits (e.g., application specific integrated circuits (ASICs)), program instructions executed by one or more processors, or combinations thereof. In addition, possible to perform this sequence of actions described entirely within the computer readable storage medium of any type of data stored on the corresponding currently set of computer instructions that when executed by the processor to perform interactive prompt described functionality. Thus, the various aspects of the invention may be embodied in many different odds max, all of which are considered to be within the scope of the claimed subject matter. In addition, for each of the described embodiments corresponding form of any such embodiments may be described herein as, for example, "logic configured to" perform the described action.
The subscriber station and high speed data (CPA) (e.g., a wireless device that supports standard 1xEV-DO), referred to herein as an access terminal (AT), may be mobile or stationary, and may communicate with one or more base stations in IUP referred to herein as modem pool transceivers (PMP) or base station (BS). An access terminal transmits and receives data packets through one or more modem pool transceivers to a base station controller CPA called a modem pool controller (ILC), base station controller (BSC) and / or mobile switching center (MSC). Modem pool transceivers and modem pool controllers are parts of a network called an access network. Access Network (AN) (also referred to herein as a radio access network (RAN)) transports data packets between multiple access terminals.
The access network may be further connected to additional networks outside the access network, such as an internal corporate network (intranet) or the Internet, and may transport data packets between each access terminal and such outside networks. An access terminal that has established an active traffic channel connection (data exchange) with one or more modem pool transceivers is called an active access terminal, and is conventionally called being in a traffic state. An access terminal that is in the process of establishing an active traffic channel connection with one or more modem pool transceivers, conventionally referred to as being in a connection setup state. An access terminal may be any data device that communicates through a wireless channel or through a wired channel, for example using fiber optic or coaxial cables. An access terminal may further be any of a plurality of device types, including, but not limited to, the PC board (PC), compact flash, external or internal modem, or radio or landline. The communication link through which the access terminal sends signals to the modem pool transceiver is called a reverse link or a reverse channel traffic. The communication link through which a modem pool transceiver sends signals to an access terminal is called a forward link or a forward traffic channel. As used herein, "traffic channel" may refer to direct, to the reverse traffic channel.
FIG. 1 shows a block diagram of one exemplary embodiment of a wireless system 100 in accordance with at least one embodiment of the invention. System 100 can contain access terminals, such as mobile phone 102 that communicate over an air interface 104 with an access network or radio access network (RAN) 120 that can connect the access terminal 102 to network equipment that provides data transmission between a packet switched data network (e.g., intra-net, the Internet and / or network operator 126) and the terminals 102, 108, 110, 112 access. As shown herein, an access terminal may be a mobile telephone 102, a personal digital assistant 108, a pager 110, which is shown here as a two-way text pager, or even a separate computer platform 112 that has a wireless communication input. Embodiments of the invention can thus be implemented at the access terminals of any kind, including entrance wireless or having wireless communication capabilities, which include, without limitation, wireless modems, card standard PCMCIA (Card International Association memory for personal computers), personal computers, telephones, or any combination or subcombination. Furthermore, the present document, the terms "access terminal", "wireless device", "client device", "mobile terminal" and variations thereof may be used interchangeably.
Returning to FIG. 1, the components of the wireless network 100 and interrelation between the elements of the exemplary embodiments of the invention are not limited to the configuration shown. System 100 is merely exemplary and can include any system that allows the terminals to the remote access, such as wireless client computing devices 102, 108, 110, 112 to communicate over the air interface between them and / or components connected via the air interface 104, and RAN 120, which includes, without limitation, a network service provider 126, the Internet and / or other remote servers.
RAN 120 controls messages (typically sent as data packets) sent to the controller 122 of the base station / control equipment packet data (CAD / CAP). BSC / NAK 122 is responsible for signaling, establishing and disconnecting bearers (i.e., data channels) between a node 100 packet data services ("PDSN") and the access terminals 102/108/110/112. If the encryption level of the communication line is enabled, the BSC / CPD 122 also encrypts the content before forwarding it over the air interface 104. The Destination BSC / NAK 122 is known in the art and will not be discussed further for brevity. Network service provider 126 may communicate with the BSC / CAP 122 via the network, the Internet and / or a public switched telephone network (PSTN). Alternatively, the BSC / NAK 122 can be directly connected to the Internet or external network. Usually, for connecting via a network or the Internet network between the operator 126 and the BSC / NAK 122 is moved data, and the PSTN for voice information is transferred. BSC / NAK 122 may be connected to a plurality of base stations 124 (BS) or modem pool transceivers (PMP). In the same manner as the carrier network, the BSC / NAK 122 is typically connected to PMP / BS 124 by a network, the Internet and / or PSTN for voice information and / or data. PMP / BS 124 may transmit data units wirelessly to the access terminals, such as mobile phone 102. PMP / BS 124, BSC / NAK 122 and other components may form the RAN 120, as is known in the art. However, it is also possible to use alternative configurations and the invention is not limited to the illustrated configuration. For example, in another embodiment the functionality of the BSC / NAK 122 and one or more PMP / BS 124 may be concentrated into a single "hybrid" module having the functionality of a BSC and / NAK 122, and PMP / BS 124.
Referring to FIG. 2 the access terminal 200 (here a wireless device), such as a mobile telephone, it has a platform 202 that can receive and execute applications, data and / or commands transmitted from the RAN 120 that may ultimately come from the network 126 operator , the Internet and / or other remote servers and networks. Platform 202 may include a transceiver 206 operably coupled to an application specific integrated circuit ("ASIC" 208), or other processor, microprocessor, logic circuit, or other data processing device. The ASIC 208 or other processor executes the application programming interface levels ("API") 210 that interfaces with any resident programs in the memory 212 of the wireless device. Memory 212 may comprise read-only memory or random access memory (ROM and RAM), electrically erasable programmable ROM (EEPROM), flash cards, or any memory common to computer platforms. The platform 202 also can include a local database 214, data that can be stored in the memory 212 used by the application is inactive. The local database 214 is typically a flash memory cell, but can be any secondary storage device, which are known in the art, such as magnetic media, EEPROM, optical media, tape, soft or hard disk, etc. The internal platform 202 components can also be operably linked to external devices such as antenna 222, display 224, button 228 "push to talk" and keypad 226 among other components, which are known in the art.
Accordingly, the embodiment can include an access terminal including the ability to perform the functions described herein. For example, the access terminal can include logic configured to combine the connection request and reservation of QoS resources into an access message and logic configured to transmit the access message to an access network. Those skilled will be understood that the various logic elements can be made in the form of discrete elements, software modules executed on a processor, or any combination of software and hardware to provide the disclosed functionality. For example, ASIC 208, memory 212, API 210 and local database 214 may share data used to load, store and execute the various functions disclosed herein and thus the logic to perform these functions may be distributed over various elements. Alternatively, said functionality may be combined into one discrete component. Therefore, signs of an access terminal of FIG. 2 must be regarded as merely illustrative, and the invention is not limited to the illustrated features or scheme.
Wireless connection between the access terminal 102 and the RAN 120 can be based on different technologies, such as code division multiple access (CDMA), multiple access with time division (TDMA), multiple access, frequency division (FDMA), global system for mobile communications ( GSM), or other protocols that may be used in a wireless communications network or a data network. Data transmission is typically between the client device 102 PMP / BSC 124 and BS / BSC 122. The NAK / NAK 122 may be connected to multiple data networks such as the network operator 126, PSTN, the Internet, a virtual private network, etc. thus allowing the access terminal 102 to access a wider network. As described above and known in the art, voice and / or data can be transmitted to the access terminals from the access network using a variety of networks and configurations. Accordingly, the illustrations herein are not intended to limit the embodiments of the invention and are intended only to assist in describing aspects of embodiments of the invention.
FIG. 3A shows a sequence of operations to combine messages in accordance with embodiments. In step 310, the terminal 302 (AP), there is an initial trigger signal to establish a connection request (e.g., pressed 228 PTT) and the information required to establish a connection with the access network 120 (AN) are combined in an access channel message (e.g., connection request (ConnectionRequest) and route update information (RouteUpdate)), provided for any QoS services, used for communication (ReservationOnRequest), etc.). To supplement the application layer data (e.g., message DataOverSignaling (DOS)) may also be combined in an access channel message to expedite communication with an end application (e.g., a group communication server, an application located on another AT, etc.). When the access message is combined with the necessary information (e.g., DOS + ConnectionRequest + RouteUpdate + ReservationOnRequest), the access message can be sent in step 320 on the access channel (KD) to the access network 120 (AN).
When combined at step 320 message received in the access network 120, the access network can process the request in step 330. In step 330, the access network may assign a traffic channel (TCH) and the requested QoS resources for the requested reservation, provided that the traffic channel and QoS resources are available . In particular, the access network 120 can acknowledge the access message (ACAck) in step 332, transmit the traffic channel assignment (TCA) at step 334 and send a message to confirm the reservation (ReservationAccept) at step 336. These messages can be transmitted in the control channel (CC) the AP 302. Message data rate control (DRC) can be sent in step 340 from the AP 302 to set the data rate with CD 120. After successfully receiving and decoding the DRC and pilot LED 120 may transmit a reverse traffic channel acknowledgment (RTCAck ) at step 350 a forward traffic channel (F-TCH). When receiving an RTCAck TD 302 may send the complete message traffic channel (TCC) in step 360 in the reverse traffic channel (R-TCH). Dedicated channels are then adjusted in the forward and reverse directions and the AT 302 and the AN 120 can both transmit data bidirectionally. Various messages communicated between access terminal 302 and access network 120 are known in the art and are registered in the document 3GPP2 C.S0024-A Version 3.0, cdma2000 High Rate Packet Data Air Interface, dated September 12, 2006 which is fully incorporated herein by reference. Accordingly, this document will not be given a detailed explanation of the messages and procedures for establishing a connection.
If the DOS message or other application layer message is further combined in the access message to the connection request, this information does not affect the establishment of the traffic channel described above. In general, application-specific data can be detected, and simply pass the appropriate destination CD 120. However, the information specific to the application, can further reduce the waiting time delay-sensitive applications, providing the necessary data (for example, PTT-call) for further processing by remote applications ( e.g., PTT-server) to establish the data transmission (e.g., PTT-call), when the traffic channels are established between the AT 302 and AN 120. Accordingly, data which includes the application layer message does not have to wait for the establishment of the traffic channels between the AT 302 and the SD 120 before being sent to the network.
Those skilled will appreciate that the QoS resources needed may vary for different applications or within applications. The following examples describe QoS design under different QoS resource scenarios.
• When traffic channel resources and QoS resources (e.g., reservation signaling during a call, and transmission medium) are available in the sector causing the TD 302, the RAN reports that QoS resources are available for both direct and reverse communication channels, sending messages FwdReservationOn and RevReservationOn for backup alarm during a call and the transmission medium. This case is shown in FIG. 3A and described in the foregoing description.
• When the traffic channel resources are available in the sector, where the caller is located 302 TD, but QoS resources for some or all of the bookings are not available, the SD 120 may nevertheless assign the traffic channel and transmit the TCA message to the caller TD 302. However, DM 120 rejects the QoS requirements of redundancy that it can not ensure ReservationReject transmitting message 302. Access to the AP traffic channel enables the AT 302 to try to complete the call establishment, notifying connection setup on a traffic channel when the QoS resources (e.g., reservation signaling during a call, and transmission media) are not available. This case is shown in FIG. 3B.
• When no traffic channel resources are available in sector caller TD, DM denies the traffic channel request by transmitting a message ConnectionDeny (e.g., standard 1xEV-DO Revision A). In this case, the QoS requirements for redundancy and fail, sending a message to the AP 302 ReservationReject. This case is shown in FIG. 3C.
If some of the reservations during call signaling and media already assigned to the AT initiating packet arrival during call setup, the AN / RAN may only activate the redundant signaling during a call, and transmission media that are not currently allocated.
As noted above, embodiments may reduce the processing delay of delay-sensitive applications. The group communication system / "push to talk» (PTT) is an example of a delay sensitive system that can take advantage of the time reduction of the compound provided herein described in association communication signals. For example, embodiments provide to the AP sending a request for the inclusion of redundancy resources required QoS (e.g., reservation signaling during a call, and transmission medium PTT-call) by transmitting a message ReservationOnRequest in the same shell access as the connection request message (e.g. , ConnectionRequest + RouteUpdate). Optionally, the message DataOverSignaling (DOS) can be combined in the same shell access. If QoS reservation forward and reverse signaling during a call assigned during PTT-call, the AT can request including QoS reservation transmission medium. These requests can be performed as part of the message ReservationOnRequest.
The group communication system may also be known as the system "push to talk» (PTT), a broadcast network service (NBS), the communication system of mailing or multipoint communication system. Typically, a group of users access terminals can communicate with each other using the access terminals assigned to each member of the group. The term "member of the group" is a group of users access terminals that are allowed to communicate with each other. While considering that the group communication systems / PTT systems exist among several participants, this system is not limited to this configuration and can apply to communication between individual devices on a "one to one".
The group may operate within the existing communication system, without requiring substantial changes to the existing infrastructure. Thus, operators and users may operate in any system capable of transmitting and receiving packet information using Internet protocol (IP), such as a multiple access, code-division multiplexing (CDMA), multiple access with time division multiplexing (TDMA) , global system of mobile communication (GSM), satellite communication systems, combinations of land line and wireless systems, etc.
Group members may communicate with each other using the allocated access terminals, such as terminals 102, 108 and 302 (AP). TD can be wired or wireless devices such as terrestrial wireless telephones, corded telephones adapted to communicate such as "push to talk", satellite telephones equipped with a functional ability to "push to talk", laptop or desktop computers, devices, paging, or any combination thereof. Furthermore, each AT may send and receive information or a secure mode, or a non-secure (clear) mode. It is understood that the term is not restricted to TH illustrated or enumerated examples, and may encompass other devices that have the capability to transmit and receive packet information in accordance with the Internet Protocol (IP).
When a group member wishes to transmit information to other members of the group, the participant may request the right to transfer by pressing the button or press the "push to talk" (eg, 228 in FIG. 2) on the TD, which makes the request, having a suitable format for transmission over a distributed network. For example, the request may be transmitted over the air interface to one or more of the AT 102 or RAP (base stations) 124. Between the PMP / BS 124 and the distributed network may be BSC / NAK 122, which may comprise known equipment interaction (s) serving node packet data (PDSN) or equipment management packet data (CPD) for processing data packets. However, queries can also be transmitted through the public switched telephone network (PSTN) network 126 operator. Network service provider 126 may receive the request and send it to the RAN 120.
As shown in FIG. 4, one or more group communication servers 402 can control the traffic of the group communication system through its connection to distributed network. Since the group communication server 402 can be connected to a distributed network through a variety of wired and wireless interfaces, geographic proximity to group participants is not necessary. Typically, a group communication server 402 manages communication between wireless devices of a fixed group of participants (DT 302, 472, 474, 476) in a PTT system. Shows a wireless network is merely exemplary and can include any system whereby remote modules communicate over a radio interface with each other and / or with the components of the wireless network, which include, without limitation, wireless network equipment and / or servers. In addition, the server group 402 group communication can be connected to a local area network (LAN) 450 server group communication.
The server (s) 402, the group communication (s) may be connected (s) to the service node packet data (PDSN), wireless service provider, such as PDSN 452, shown in this case as being in a network 426 operator. Each PDSN 452 may communicate with the controller 464 of the base station in the base station equipment 460 via the control packet data (HPD) 462. The CAP 462 may be located in the base station 460. The network operator 426 controls messages (generally in the form of data packets) is sent to the MSC 458. The MSC 458 can be connected to one or more base stations 460. In the same manner as the carrier network, the MSC 458 is typically connected to the BTS 466 by a network, and via the Internet to transfer data, and via the PSTN for voice transmission. BTS 466 ultimately transmits messages wirelessly to the wireless AP, such as mobile telephones 302, 472, 474, 476, in a manner known in the art, and receives messages from them. Accordingly, the usual elements of group communication system will not be further described. Furthermore, although the herein described specific aspects of specific systems (e.g., PTT, QChat®, 1xEV-DO) to provide additional details and examples, embodiments of the invention are not limited to these specific illustrations.
As described above, the AT 302 requests a traffic channel for communication (e.g., PTT-call). PTT-call may originate from the AP-302 initiator, and if the traffic channel and QoS resources for signaling during a call, and transmission media available (additional details regarding the QoS resources are shown below in FIG. 5). In conventional systems, the AT 302 must establish a connection on a traffic channel with AN 120 and then request the QoS resources. However, to reduce this delay in accordance with embodiments of the invention, the signaling messages required to establish a PTT-call are combined in an initial access channel message with the original connection request.
Standard 1xEV-DO Revision A is designed to provide efficient access to packet data networks and is widely based on the Internet because of its network architecture. Data traffic moves over the Internet Protocol (IP) to the PDSN 452, the HPD 462 and RAN 120 can be based on standard protocols Engineering Development Group Internet (IETF), which support means of differentiating traffic based on QoS requirements. QoS between the AT 302 and the network standard, 1xEV-DO Revision A is configured as described in the specification 3GPP2 X.S0011 -004-C Version 2.0 cdma2000 Wireless IP Network Standard: Quality of Service and Header Reduction, the contents of which are incorporated herein by reference. Data traffic transmitted over the air interface between the AT 302 and the RAN 120 can be configured for appropriate QoS treatment protocols via 1xEV-DO Revision A, as described in document 3GPP2 C.S0024-A Version 3.0, referenced above. Standard 1xEV-DO Revision A provides standard mechanisms to ensure QoS in the AP (intra-AT) between TD (inter-AT). AT QoS provides differentiation within the data streams belonging to the same user, while AT QoS provides differentiation between packets belonging to different users.
To ensure QoS should be available through-traffic differentiation. All network components, including TD 302, the RAN 120 (BTS 466, BSC 464), PDSN 452, and Internet routers should implement / support QoS. Through the network QoS 1xEV-DO Revision A may be achieved through the following mechanisms.
• Packet filters: filters packets at the PDSN is a straight flow of traffic to the AP, and only affect QoS, which should be used to direct data traffic. TD passes requirements QoS, packet filters are installed in the PDSN, as described in the specification 3GPP2 X.S0011 -004-C Version 2.0 cdma2000 Wireless IP Network Standard: Quality of Service and Header Reduction.
• QoS Profiles (IDs (identifiers) profiles): QoS Profiles and / or Profile IDs - the mechanism for determination (or task) of the respective air parameters and network QoS requirements for a data service. This "condensed" identifier that the AT uses when requesting a QoS reservation for a flow with the RAN. Standard appointment ID profiles available for different data services, described in the document TSB58-G Administration of Parameter Value Assignments for cdma2000 Spread Spectrum Standards, the contents of which are incorporated herein by reference.
• Marking reverse traffic: AT can mark reverse traffic data in accordance with the structure and standards, service differentiation (DiffServ). These markings define the QoS network treatment, which is required for data transmitted in the PDSN.
QoS network 1xEV-DO Revision A is also based on the proper mapping or binding of the following elements for the AT PPP session, such as the following:
• Flow IP (Application) Application layer QoS requirements at the AT and PDSN are determined by identifying unique IP flows. Mark redundancy associated with the flow of IP to identify the QoS requirements of the flow between the AT and the RAN. IP flow is then mapped onto RLP flow, which best meets QoS.
• Flow RLP (Link): flow radio link protocol (RLP) is partitioned based on QoS requirements (e.g., RLP parameter configuration) for upper layer flows. IP flows with the same QoS requirements can be displayed on the same flow RLP. In reverse RLP flow is mapped to RTCMAC flow (media access control reverse data traffic channel).
• Feed RTCMAC: RTCMAC distribute flows based on the requirements of QoS, which define physical layer latency and / or the need for top-level flow capacity. For example, the flows may be flows of high capacity or low latency. RLP flows with the same QoS requirements can be displayed on the same stream RTCMAC.
FIG. 5 shows a plurality of RLP flows 500 for TD 302 supporting PTT, which is in communication with access network 120. The QoS requirements for each flow can be determined via QoS profiles. As noted above different applications can have different QoS requirements. For example, PTT on 1xEV-DO Revision A receives high priority data and low latency by determining the QoS requirements for the network. An exemplary system can use PTT distribution of the three IP flows in the TD, the flow for signaling at call setup; flow for signaling during a call; and Flow medium. Each IP flow has specific QoS requirements, and it is displayed on three separate RLP stream. TD can additionally use the default "best possible» (BE) flow. QoS requirements for the transmission medium, is believed to be similar to the requirements for VoIP transmission medium, and therefore this RLP flow can be shared with VoIP.
While the above description provides many details specific to PTT system / network QChat® and 1xEV-DO, for detailed illustrations of various aspects of embodiments of the invention, those skilled will be understood that the embodiments are not limited to any specific application and / or network. Embodiments of the invention may include any application that has QoS requirements. Moreover, embodiments may also include any network that can support the allocation of QoS resources, combined with the initial connection setup request.
FIG. 6 is a flowchart showing the process of combining in accordance with embodiments of the invention. For example, in step 610, the method may include the application QoS resource request that identifies the desired compound (e.g., PTT-call). May provide additional posts for the association (for example, a message DOS) 620, if the additional message and access probe has a place. Request for access to the joint connection (e.g., access probe) can then transmit in step 630 from the application level to lower layers for combining requested messages in the access probe. In this document, the application layer can include the requesting application (e.g., PTT client) and unifying API that facilitates communication between the application layer and the lower layers (e.g., RLC, MAC and physical layers). However, it should be recognized that embodiments are not limited to this configuration. For example, the application itself may contain the functionality of combining PPIs.
In step 634, after receiving the request can be combined to add QoS requirements to the access probe. Similarly, at step 636 DOS message can be added to the access probe, if necessary and if the access probe there is sufficient space. As a supplement to step 638 the connection request and route update message is added to the access probe. In step 645 can perform checks to determine whether the combined message is completed. If not, the process may go back to check the missing messages, as they may be delayed. A delay element (e.g., timer) can also be set at the application layer at step 640 to allow access probe combination.
The process may repeat step 650 until the application layer is not accept instructions from the lower levels, that association is completed message in step 645 (or when the end time of the event and will sent an access probe). After receiving the acknowledgment delay access probe can terminate at step 660, and access probe can be transmitted in step 670.
As described above, the trigger signal (e.g., 310) can be any event that causes an application to initiate a connection request with QoS requirements, which are known application. The trigger signal can be activated manually or through the activation of a hardware programmable keys can be activated in response to the received signal (e.g., voice command, signal from the network, etc.) or can be activated in response to condition detected application.
For example, as shown in FIG. 7, the access terminal (AT) 472 may receive a trigger, such as a paging message or a call setup message 705 in the PTT. In particular, a call setup message 705 may be transmitted via PDSN 452 and AN 120. Access network 120 may send a call setup message by channel 710 to control the designated AP 472. After receiving and decoding the packet call establishment TD 472 may determine that the requested connection (e.g. , PTT-call) uses the resources of QoS. Accordingly, a call setup message received from the network can serve as a trigger signal for starting the subsequent association response.
For example, the AT 472 can respond to the combined query 720, which includes a connection request (e.g., ConnectionRequest + RouteUpdate), QoS reservation (e.g., ReservationOnRequest) and optionally, an application layer message (e.g., DOS) on the access channel. That DOS includes application data enables the recipient to send them to establish a traffic channel. Request for QoS resources allows for the allocation of the need for QoS resources to establish a traffic channel. Accordingly, the reaction rate of the communication system can be improved. When receiving the connection request a traffic channel and requested resources can be assigned 712 to the access network (AN) 120. The traffic channel assignment message (TCA), QoS resources confirm and validate the access channel may be transmitted in step 714 to the AP 472. Establishing traffic channel may continue to stages 722, 716 and 724 until 120 and SD, TD and 472 would not be ready to transmit and receive data as described above and known in the art. Accordingly, a detailed explanation will be omitted.
