One example includes a capability gateway that is comprised of a receiver and a transmitter. The receiver receives, from a ground station associated with a satellite system, a standard protocol associated with the ground station and a non-standard alternate protocol that includes alternate service layers inserted into an inter-layer boundary of standard radio layers, the alternate service layers providing end-to-end signaling between the capability gateway and a user equipment. The transmitter transmits the non-standard alternate protocol to the user equipment.

An apparatus and method for increasing Scheduling Request efficiency in a wireless communication system includes a stepof configuring periodic timing opportunities for sending the scheduling request. A next stepincludes detecting new data arriving in an empty queue to trigger a scheduling request. A next stepincludes sending a scheduling request at selected SR opportunities until a response to the scheduling request is generated.

Increasing scheduling request efficiency in a wireless communication system

One or more gateways (and) as serve to interconnect the discrete call facilitation platforms (and) of a given communication network with an external communication network () as provided with the routing addresses of such discrete call facilitation platforms. The discrete call facilitation platforms, however, are not provisioned in a reciprocal fashion. Instead, the discrete call facilitation platforms are only provided with a subset of available gateway addresses. In a preferred approach, this is accompanied by less-than-fully-meshed connectivity between the gateways and the discrete call facilitation platforms.

Transcoding needs and selection are performed by a central call control function (). Each transcoder () registers with the appropriate call control (). The call control then determines whether a vocoder is required at all. If vocoding is required, call control () selects the appropriate transcoder () and inserts the appropriate transcoder into the bearer traffic stream ().

Vocoder selection method

A third generation (3G) gateway provides the facilities for extending a number of internet protocols between a second generation (2G) network and a 3G network. The various messages of a session initiation protocol (SIP) are extended to provide user identification and server identification subfields. The SIP message extensions facilitate the communication of 2G and 3G networks for the purposes of implementing push-to-talk and dispatch service features.

Interface call signaling protocol

For a network server () communicating with a wireless unit () via a Session Initiation Protocol, a retransmission method () first sets a timer based upon a time likely for a mobile unit to respond (). Then the network server waits for a response (). When the timer set for the kind of mobile unit being used expires (), a retransmit of the original SIP request takes place (). Optionally, modes for waiting may include a linear mode () and an exponential mode ().

Session initiation protocol retransmission method

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

Method for joining dispatch calls

The voice signaling gateway () provides group call and call back services among iDEN network () users () and a number of other various networks () users (). The voice signaling gateway has packet data interface () and web interface () In an alternate embodiment of the invention, an integrated applications server () is added to the voice signaling gateway () to provide group call services. The integrated applications server has the functions for supporting group calls which were within the voice signaling gateway () and forms a stand-alone special feature system.
