Abstract: A media selection and insertion control device implements a method for selecting media for delivery to a plurality of users at an incident. The media selection and insertion control device: receives a plurality of media inputs from multiple media sources; receives capabilities of devices of users at an incident; receives resource capabilities of a set of networks to which the users are communicatively coupled; receives a set of incident-based rules and applies these rules to the plurality of media inputs to select media inputs to deliver to the users; and determines a mode of delivering the selected media inputs to the users based at least on the capabilities of the users' devices and on the resource capabilities of the set of networks to which the users are communicatively coupled.

Abstract: A mobile station (129) will have the capability to detect an impending cell change and Routing Area Update (RAU) and will send a “Request Deny” message to the network via the serving cell prior to handing over. The PTT server (131) will use the Request Deny message as an indication that an inter-SGSN RAU may be occurring. The PTT server (131) will wait for the mobile station to reappear, after handover, on a new cell. If the mobile does not reappear, an inter-SGSN RAU may be assumed and the PTT server (131) will release the floor and deny the floor to all mobile stations. This action forces all mobile stations back into idle mode and prevents them from seizing the floor. The PTT server (131) will then wait for the mobile station (129) performing the RAU to reappear on a new cell before opening the floor to all mobile stations.

Abstract: A Push-to-X over Cellular (PoC) server (351) receives a server registration message (301) for a first called device from a second server. The PoC server (351) receives a PoC invitation message (310) with PoC preferences and a message (313) from an originating device (311). The PoC preferences determine what device to call first (e.g., a mobile device 315, 317) and how many hops the call can be forwarded (e.g., to a voicemail server) if the first-attempted device is not available, before discontinuing the connection. If a trigger, such as time elapsed, occurs for the first-attempted device (350) and the PoC preferences permit, the PoC server (351) sends an invitation message (360) to the second server (391). If the second server (391) is a recording server, the invitation message (360) includes a message (363) from the originating device that is compatible with the capabilities of the recording server (391).

Abstract: A method for controlling message transmission by a telecommunications device (110). A trigger configuration signal (150) including a dynamic logic expression (160) is received by the telecommunications device (110). The dynamic logic expression (160) defines one or more conditions associated with the transmission of a message (140). The telecommunications device (110) applies the dynamic logic expression (160) and transmits the message (140) if the dynamic logic expression (160) is satisfied.
