摘要:
A system and method for transmitting information from a sender at a source mobile unit to a recipient at a destination mobile unit. A sender at a source mobile unit (102) may select a destination mobile unit (106). An overture element may then be formed. The overture element may contain information from the sender at the source mobile unit (102) indicating that the sender desires to establish a wireless connection with the recipient at the destination mobile unit (106). At least one data burst message may be formed and the overture element may be incorporated into the data burst message.
摘要:
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.
摘要:
During the course of a push-to-talk talkgroup wireless communication, decisions (21) are made regarding possible subsequent push-to-talk communication needs for the group. Based at least in part upon such decisions, a network location is identified (22) to provide talker arbitration support for this talkgroup. In one embodiment the identified network location can comprise a mobile station, such as a mobile station that comprises a member of the talkgroup. In a preferred embodiment, the talker arbitration capability is then assigned (24) to the identified network location.
