Abstract: A method for increasing performance of a wireless communication system is provided. The method includes determining (220) quality of service parameters that will result in a reduced likelihood that an application assigned the determined quality of service parameters will be scheduled for transmission, identifying (230) an application to be provided service that is less than best effort, and assigning (240) the determined one or more quality of service parameters to the identified application. In an embodiment, the method further assigns (250) a dedicated bearer to the identified application and either does not schedule (260) the dedicated bearer at all or schedules (270) the dedicated bearer less frequently compared to a frequency of scheduling a default bearer.

Abstract: An apparatus and method for establishing a session in a communication network supporting multimedia group calls. A first step (202) includes determining streams for a multimedia group call by the service entity. A next step (204) includes providing an indicator of the resources required for at least one stream of the group call by the service entity. A next step (206) includes paging the subscriber unit with the indicator for the at least one stream of the group call by the service entity. A next step (208) includes ascertaining the capabilities and resources of the subscriber unit. A next step (210) includes establishing a channel for only those streams of the group call for which the capabilities and resources of the subscriber unit are sufficient with respect to the indicator for those streams.

Abstract: A method for providing dynamic group call among a group of users both wireless (10-30) and wireline (40) places the selectability of the call in the hands of an originating user (10). An originating user (10) may make a fixed number of entries (80). The originating user (10) can create a dynamic group call, add a group call list for later execution, add a member to the group call list, or create a dynamic group call list and immediately execute a group call (92). The method for dynamic group call also provides for selecting a time to live for each group call entry (81) in database (60). This parameter time to live is directly selectable by the originating user (167) or the server. In addition, any member to a previous or existing group call may rejoin or reestablish the dynamic group call (220).

Abstract: A proactive speculation method decreases the call setup time for private calls (200) and selective dynamic group calls (300). In a push-to-talk dispatch network (40) an originating mobile unit (10) sends a wake-up packet (54, 114) to the dispatch network (40). Prior to initiating the push-to-talk function, the target mobile units (20–30) receive a wake-up packet (68, 146–148) from network (40). Thereby, prior to establishing the push-to-talk function, each of the mobile units in the push-to-talk call have been coupled via RF links. If the originating mobile unit has a current IP address, direct wake-up packets (72) may be sent.

Abstract: The voice signaling gateway (10) converts signaling and bearer traffic information between iDEN network (20) and various other networks (30–60). The voice signaling gateway includes a signaling portion (14) and a bearer traffic portion (12). The voice signaling gateway interfaces with any networks which support session initiation protocol (SIP). Further, the voice signaling gateway is capable of. interworking with both 3G and 2G type networks.

Abstract: A user terminal (10) using an internet protocol using session initiation protocol to interconnect a number of user terminals (11–13) in a conference call. A conference bridge (30) or user terminal (10) detects speech of one of the user terminals (203). A “babble ” timer is started (207). The speaker is allowed to continuously speak until silence is detected (217) or until the “babble” timer timers out (211).

Abstract: A common services and applications agent (10) handles a number of input sources of voice and data information (11–16). These sources of voice and data information are converted (20) to session initiation protocol. The session initiation protocol for the voice and data information is provided to the communication network (40).

Abstract: A dispatch call setup method selects (101) either a forced dispatch call (105) or an invite dispatch call (103). The originating unit (20) of the dispatch call may select either option. Depending on how the required target users (30, 40) respond, the originating terminal has the option to complete the call (119). The terminating unit may accept, reject or convert the forced dispatch call (127). Further, the target may establish preset preferences which accept, reject or allow user controls for an invite dispatch call (139).

Abstract: A user terminal (10) initiates an internet protocol using session initiation protocol to interconnect a number of user terminals (11–13) in a conference call. Signaling connections (41, 42, and 43) are established between one user terminal and each of the plurality of user terminals. Common bearer formats are negotiated among the plurality of user terminals (113). If a common bearer format exists (115), the conference bridge is established for data (voice) transmission (127).

Abstract: An arrangement for compressing (20) and uncompressing (40) system set up messages between a client and a server employing Session Initiation Protocol transmits a template (200) between client (10) and server (30). A template is pre-placed (78) by clients or servers with other clients or servers. During execution time when a client requests services by connecting to a server only a minimal template (106) is transmitted from client to server. The server then reconstructs (40) the original uncompressed message.

Abstract: For a push-to-talk function in a mobile communication system (30), an indication is received (35) by a user (50) that the talking floor is available. Next, an uplink temporary block flow is established (36). Prior to release of the uplink temporary block flow by the mobile communication system, a refresh message is sent (39) to hold the uplink temporary block flow. Downlink temporary block flows may also be refreshed by this method, or by the mobile communication system. Then the requesting user may enable the push-to-talk function. These techniques can improve talker arbitration and call setup delays for push-to-talk.

Abstract: A hitchhiker device (20) has a wireless communication capability. The hitchhiker device is located in a non-network area (10) and requires the transmission of a wireless message. The hitchhiker device requests via an RF link (25) a donor device (30). The hitchhiker device transmits the message to the donor device. The donor device stores the wireless message. Subsequently, the donor is relocated to a wireless area and transmits the stored message via a network link (35).

Abstract: A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203-208 that are in location areas 260, 261. The sites join respective location area multicast addresses to receive messages from other sites in their location area. Communication units desiring to participate in talkgroup calls need only to register affiliation with a first site of the location area. Upon the first site receiving an affiliation message, it joins a payload multicast group address to receive payload for the talkgroup. In alternative embodiments, the first site sends, via the location area multicast address, either control message(s) or tunneled payload associated with the talkgroup call to secondary site(s) of the location area.

Abstract: A mobile device (80) is coupled to a dispatch server (50) via a mobile network (60, 70) and an internet protocol network (40). The mobile device triggers a push-to-talk request which is processed by the dispatch server. The dispatch server then transmits this push-to-talk request to a family radio service (FRS) gateway (30). FRS gateway (30) converts this digital request to an analog request and broadcasts the request via a base station 20 to a family service radio (10). The FRS radio can broadcast back to the FRS gateway, which will vocode the analog request, and transmit it back to the mobile device via the dispatch server. This invention allows mobile devices (cellular) equipped with PTT applications to network with FRS radios.
