    Abstract: The application relates to group communications over multimedia broadcast-multicast services MBMS. E-MBMS services can be used to distribute multicast data to groups and could be useful in group com¬ munication systems. However, in conventional E-MBMS services, the time to establish a new flow is on the order of 10 seconds. This laten¬ cy is unacceptable for high performance group communication sys¬ tems, such as a push to talk system that requires less than 1 second from the call initiation from the originator to the granting of the floor to at least one group member. This problem is solved in that a multi¬ cast flow is pre-reserved for the media flow in such a way that it can be quickly established. Furthermore, another multicast flow, which is "always-on", is used as a sort of application layer paging flow in order to indicate activity on the media flow. The user equipment monitors the paging flow (Multicast flow#l) regarding activity of a group com¬ munication (Call Announcement) and upon receipt of a call announce message, switches to the corresponding media flow (Multicast flow #2).

    Abstract translation: 该应用涉及通过多媒体广播多播服务MBMS的群组通信。 可以使用E-MBMS服务来将组播数据分发到组,并且可以在组通信系统中有用。 然而,在传统的E-MBMS服务中,建立新流程的时间大约是10秒。 对于高性能组通信系统来说,这种延迟是不可接受的,例如从发起者的呼叫发起到授权地址至少一个组成员需要不到1秒的一键通系统。 解决这个问题的原因在于可以以可以快速建立多媒体流的方式预先保留多播流。 此外,作为“始终在线”的另一组播流被用作一种应用层寻呼流,以便指示媒体流上的活动。 用户设备监视关于组通信(呼叫通知)的活动的寻呼流(组播流#1),并且在接收到呼叫通知消息时,切换到相应的媒体流(组播流#2)。

    Abstract: A service for Public Safety (PS) and Law Enforcement (LE) users on commercial wireless networks which assure them access to packet data services. The service request is application based. The applications that are for official use, by the PS/LE users, could have a reserved priority level associated with them. The reserved priority level could be higher than a normal commercial user. The network could use the priority to distinguish users, and dynamically allocate and optimize network resources. The network could use priority level information to perform access, admission, and congestion control. The PS/LE user could use the official applications while on duty and un-official ones while off duty, thus, additionally freeing up network resources. The PS/LE users could then use advanced commercial packet data services, without the need for a private network, while at the same time making it feasible for commercial networks.

    Abstract: A system and method for enabling a wireless communication device to register a temporary public IP address assigned to the device by a network access translation module, when the device is initially informed only of a private, non-routable IP address that has been assigned to it. In one embodiment, the device sends a "blind" registration message to an SIP server, with the private IP address of the device being translated to the public IP address by the NAT and with the SIP server registering the "originator" address in the header. In another embodiment, a registration server detects a message indicating the public IP address and sends the public IP address back to the device, so that the device can conventionally register the address with the SIP server.

    Abstract: A method and apparatus for reducing latency in a group communication network (100) provides for a significant reduction in the actual total dormancy wakeup time and the PTT{XE"PTT"} latency by exchanging group call signaling even when mobiles (102, 102, 106) are dormant and no traffic channel is active. The method and apparatus provides for exchanging the group call signaling through the use of the short data burst (SDB) message signaling. The method and apparatus provides for re-establishing dedicated traffic channels for the talker mobile and the dormant listener mobiles advantageously in parallel.

    Abstract: In an embodiment, a network device obtains a plurality of data packets that are each associated with one of a plurality of different streams, wherein each of the plurality of obtained data packets includes a header portion with stream-specific routing information. The network device strips the stream-specific routing information from the plurality of obtained data packets to produce a plurality of stream-specific payload portions, which are merged into a shared payload portion of a stream-multiplexed data packet that includes common routing information for the plurality of streams in a common header portion. The network device transmits the stream-multiplexed packet to a target device, and the target device determines whether any of the plurality of different streams are relevant to the target UE based on stream-mapping information contained in the stream-multiplexed packet, and selectively decodes and processes the stream-specific payload portions corresponding based on the determination.

    Abstract: An aspect of the disclosure is related to prioritizing users during a server failure. A client device or a central non-regional component detects that a server arbitrating a packet-based voice communication service in a first region has failed, and redirects the client device registered to utilize the packet-based voice communication service in the first region to a second server providing the packet-based voice communication service, wherein the redirecting is based on a priority level of a user of the client device. An aspect of the disclosure is related to peer-assisted failover recovery. A first client device detects that a server arbitrating a packet-based voice communication service in a first region has failed, and notifies a second client device in the first region that the server arbitrating the packet-based voice communication service in the first region has failed.
