A method of function prioritization in a multi-channel voice-datalink radio is provided. The method comprises suspending transmission of one or more data messages on a communication channel when transmission of a voice message is active on the communication channel, buffering the one or more data messages while the transmission of the voice message is active, and resuming transmission of the buffered one or more data messages on the communication channel when the transmission of the voice message ends.

Apparatus, and an associated method, for a PoC (Push-to-Talk over Cellular)-capable communication system. A user equipment PoC box is provided, and a corresponding network PoC box is also provided. A transport mechanism is defined and provided by which to communicate a PoC media burst that is delivered to a PoC box and stored thereat. Control functionality is provided by which to control disposition of the media burst, such as to make notification of a delivered media burst or to dispose of the media burst when no longer needed, is further provided.

Provided are a method, system, device for controlling congestion or overload and an eNB. The method includes: one or more eNBs configured to detect congestion or overload of user plane data are selected, and the one or more eNBs selected are notified; the one or more eNBs selected detect a congestion or overload event of the user plane data; when a triggering condition is met, the one or more eNBs selected send congestion or overload indication information to a GCS AS; and the GCS AS determines a start or end of congestion or overload which occurs in an MBMS area according to the congestion or overload indication information, and correspondingly selects a manner in which trunking service data are sent. By the technical solutions of the disclosure, the problem of influence for a trunking service when congestion or overload occurs in a network may be solved.

A process for dynamic talk group formation in a wireless communication system as a function of subscriber unit movement relative to a defined incident location includes receiving, at an infrastructure controller device from one of a third subscriber unit and a dispatch console, a request for forming a new talk group relative to a defined incident location. The infrastructure controller device determines a direction of movement of a plurality of subscriber units relative to the defined incident location. The infrastructure controller device then forms a talk group including a first subscriber unit from the plurality of subscriber units determined to be moving towards the defined incident location and not including a second subscriber unit from the plurality of subscriber units determined to not be moving towards the defined incident location.

A method for optimizing group communication services, the method including determining a current location and an assigned home server for one or more devices associated with each of a plurality of group members, determining whether the one or more devices of the plurality of group members has moved to a visiting location, wherein the visiting location is a location outside of locations associated with the assigned home server based on the current location and assigned home server for the one or more devices, and assigning a group control application server associated with the visiting location to the to the one or more devices to serve as the assigned home server.

A method for optimizing group communication services, the method including determining a current location and an assigned home server for one or more devices associated with each of a plurality of group members, determining whether the one or more devices of the plurality of group members has moved to a visiting location, wherein the visiting location is a location outside of locations associated with the assigned home server based on the current location and assigned home server for the one or more devices, and assigning a group control application server associated with the visiting location to the to the one or more devices to serve as the assigned home server.

A wireless communication device associated with a mobile operator network transmits an authentication request for network access via a wireless access point (AP) using a transceiver other than the cellular network transceiver. Device authentication can occur directly with the mobile operator network or via a proxy server. Upon authentication, the requesting device may access a wide area network in a data off-load operational mode and the data flow to and from the device via the AP is monitored and reported to mobile operator network associated with the requesting device. The wireless communication device can communicate with any of a plurality of APs distributed in a venue during the data off-load operational mode.

One embodiment of the present invention relates to a method by which a mission critical push to talk (MCPTT) server establishes a group call in a wireless communication system, comprising the steps of: determining whether to add a user equipment (UE) to an ongoing group call; transmitting information relating to the ongoing group call to the UE if it is determined that the UE is added to the ongoing group call; and receiving an OK response for the ongoing group call from the UE.

Disclosed are a method and device for realizing WIFI talkback of a terminal, related to the field of mobile communications technologies, wherein the method includes the following steps: a calling terminal initiating a request for obtaining a dynamic IP address via a WIFI wireless local area network (LAN); after receiving the request, a called terminal judging whether the calling terminal has successfully obtained the dynamic IP address; if the called terminal determines that the calling terminal has successfully obtained the dynamic IP address, it determining whether the calling terminal has enabled a talkback function; if the called terminal determines that the calling terminal has initiated the talkback function, the called terminal sending a message to the calling terminal for indicating that the called terminal is online, thereby enabling the calling terminal and the called terminal to perform the WIFI talkback.

A network-to-network interface (NNI) gateway system for inter-communication between a Push-to-talk-over-Cellular (POC) system in a first wireless network and an Integrated Digital Enhanced Network (iDEN) system in a second wireless network. The POC system performs a POC call session for POC mobile units in the first wireless network. The iDEN system performs a Push-to-Talk (PTT) call session for iDEN subscriber units in the second wireless network. The gateway system bridges the iDEN system to the POC system, such that the POC system is exposed to the iDEN system as an emulated iDEN system, the iDEN system is exposed to the POC system as an emulated POC system, and calls are placed across the first and second wireless networks between the POC mobile units and iDEN subscriber units.
