Abstract: A method and apparatus are disclosed that provide expedited recovery in a communication system employing redundancy. The method includes establishing connections between a second server and each of a first mobile device and a second mobile device; receiving, by the second server from the first mobile device, an indication that a first server has recovered, wherein the first server and the second server are redundant servers and wherein the second server acts as a backup server for the first server; and based on the indication received from the first mobile device, informing, by the second server, a second mobile device of the recovery of the first server, thereby expediting a connecting, or a re-connecting, of the second mobile device to the first server.

Abstract: A communication system is provided that sets up a group call, originated in a first originating network, in a second originating network when insufficient resources are available in the first originating network, wherein the first originating network is one of a narrowband network and a broadband network and the second originating network is the other network of the narrowband and broadband networks. An infrastructure device of the first originating network receives a first group call request from an originating mobile device and, in response to receiving the request, determines that insufficient resources are available in the first originating network for allocation to the mobile device for the group call. In response to determining that insufficient network resources are available, the infrastructure device arranges to set up an originating leg of the group call for the originating mobile device in the second originating network.

Abstract: A communication system is provided for controlling group affiliation in a wireless communication system, wherein a group management server determines, or modifies, a set of one or more group affiliation parameters and group de-affiliation parameters associated with a mobile device based on capabilities of another mobile device and/or a set of one or more group affiliation parameters and group de-affiliation parameters associated with the another mobile device. The mobile devices may be mobile devices of a same user or may be mobile devices of different users. In other embodiments of the present invention, in response to receiving a request to initiate a group call involving a group that includes multiple mobile devices of a same user, the group management server may select only one of the multiple mobile devices to participate in the group call and arrange for only the selected mobile device to participate in the group call.

Abstract: An enhanced push to talk (PTT) method, a network, and a PTT server provide floor control and media traffic optimization for push to talk over cellular (PoC). Specifically, multiple Session Initiation Protocol (SIP) sessions are contemplated between controlling and participating servers while only requiring a single Real Time Protocol (RTP) session for media and a single Real Time Control Protocol (RTCP) session for floor control. In the single RTP and RTCP session, the synchronization source identifier (SSRC) can be used to differentiate between users equipment (UEs) at the controlling and participating servers.
Abstract translation: 增强型一键通（PTT）方法，一个网络和一个PTT服务器为蜂窝通话（PoC）提供楼层控制和媒体流量优化。 具体来说，在控制和参与的服务器之间考虑了多个会话发起协议（SIP）会话，而仅需要用于媒体的单个实时协议（RTP）会话和用于楼层控制的单个实时控制协议（RTCP）会话。 在单个RTP和RTCP会话中，同步源标识符（SSRC）可用于区分控制和参与服务器的用户设备（UE）。

Abstract: A device, system and method for determining and providing bearer indications for a group communication session is provided. A server for managing a group communication session determines active communication devices of the group communication session. The server determines bearer indications for the active communication devices, the bearer indications indicating: whether a respective bearer of an active communication device is a unicast bearer or a multicast bearer; and whether the respective bearer has a guaranteed bit rate or no guaranteed bit rate. The server transmits, to each of the active communication devices, the bearer indications to cause each of the active communication devices to provide, at a respective notification device, a notification of the bearer indications.

Abstract: A method and system for maintaining ambient monitoring capability for a communication device. The method includes using a first target identity to identify the communication device in a first ambient monitoring session with an ambient monitoring device. The method also includes, while in the first ambient monitoring session, receiving, by an electronic processor of the communication device, a communication service state change notification for the first target identity. The method also includes, while in the first ambient monitoring session, determining a second target identity to identify the communication device in a second ambient monitoring session that has not been established. The method also includes, while in the first ambient monitoring session, transmitting, to the ambient monitoring device, the second target identity.

Abstract: Method and system for controlling a plurality of communication devices. One system includes a server for a communication system in which each of a plurality of communication devices is affiliated with at least one talk group among a plurality of talk groups. The server includes an electronic processor configured to determine whether each communication device of the plurality of communication devices is in a connected state. The electronic processor is further configured to determine that at least one talk group does not include any communication devices affiliated with the at least one talk group that are in the connected state. The electronic processor is further configured to place at least one communication device affiliated with the at least one talk group in an artificially-connected state based on at least one characteristic of the communication devices affiliated with the at least one talk group.

Abstract: A device, system and method for managing channel and/or talkgroup assignments is provided. A memory stores: a first list of channels associated with a device identifier of a mobile device; and a second list of channels associated with: a user identifier of a user; and attributes of the user. A controller: receives, via a communications unit, from the mobile device, the user identifier indicating a log-in to the mobile device by the user; selects a subset of the first list of channels, to be temporarily assigned to the mobile device when the user is logged into the mobile device, based on the attributes of the user; and transmits, via the communications unit, to the mobile device, a combined list that includes the subset of the first list of channels, and the second list of channels, to enable the mobile device to communicate using channels in the combined list.
