    Abstract: An interconnect communication system is provided that provides for dispatch-type services including Instant Access call set up, talkgroup creation and management, and in-band floor arbitration and mode switching that employ in-band signaling tones. By providing talkgroup creation and management and in-band floor arbitration that are transparent to the underlying network, the talkgroup creation and management and in-band floor arbitration may be implemented in a legacy system without the need to modify the network and regardless of the type of network employed. Furthermore, by providing Instant Access call set up procedures and mode switching procedures that are capable of utilizing modified versions of known messages, the procedures may be implemented in a legacy system in a simplified manner, minimizing the impact of an addition of such procedures to a legacy network.

    Abstract: A communication system (100), upon receiving an instruction to transfer deferrable data, determines whether an air interface (128) is congested and, when the air interface is congested, defers a transfer of the deferrable data or transfers the deferrable, lower priority data as higher priority data. When, during a transfer of deferrable data, the system determines that the air interface is congested, the system may terminate the call and save a state of a partially completed deferred data transfer. Subsequent to the termination of the call, the system establishes another data connection over the air interface and transfers any remaining, not yet transferred deferrable data. In order to discourage subscribers from transferring higher priority data as lower priority data, the system may further restrict a transfer of lower priority data to designated time periods while allowing a transfer of higher priority data during the designated time periods and other time periods.

    Abstract: The present embodiments provides for notifying a remote communication device (124/126) when a local wireless device (122) loses its wireless link (112). A method detects when a wireless connection (112) is lost with a first communication device (122) , identifies a second communication device (124.126) that is communicating with the first device, and notifies the second device of the lost link. The notification of the lost link is supplied while the method provides batch communications. Voice communications, where a remote device is notified when a local device loses its wireless connection, can be provided. The second device can be determined by querying a server (150). The notifying can include forwarding an in-band tone, and/or generating a real time protocol packet. The loss of the link is detected through a radio access network (134), a packet control function (132), and/or a mobile switching center (136).

    Abstract: A wireless communication unit communication transport path monitor ( 10 ) monitors ( 20 ) at least one wireless communication unit specific parameter, and in response a wireless communication system inactivity timer ( 11 ) is set ( 21 ) as a function, at least in part of the monitored wireless communication unit specific parameter. The inactivity timer for a given wireless communication unit tends to be shortened when a communication transport path experience is sufficiently consumptive of unit and/or system resources. Optionally, at least one wireless communication system specific parameter is monitored ( 22 ) and/or at least one fairness parameter is checked ( 23 ), and the inactivity timer is set ( 21 ) as a function at least in part of the system specific parameter(s) and the fairness parameter. Similarly, if a predetermined condition is met, the inactivity timer for a given wireless communication unit may not be shortened.
