  • Patent number: 8380228
    Abstract: Systems and methods for managing power consumption on a trunked network include listening to a control channel on a trunked system with a trunked pager, and receiving a voice channel assignment. The trunked pager listens for voice traffic on the assigned voice channel while in a standby mode. Voice traffic is detected and the trunked pager determines whether the voice traffic is for a communication group that includes the trunked pager. If so, the trunked pager unmutes and listens to the voice traffic. Upon termination of the voice traffic, the trunked pager returns to the control channel to listen for a different voice channel assignment. Otherwise, the trunked pager directly returns to the control channel to listen for a different voice channel assignment.

  • Patent number: 8369876
    Abstract: The invention relates to a method for tracking locations of mobile terminals in a communication network. Further, the invention relates to a communication network and apparatuses therein capable of performing individual steps of the method according to different embodiments of the invention. To decrease the signaling load imposed by mobility related signaling the invention suggests to group mobile terminals in so called mobility groups and to reduce the signaling overhead by performing a location update on a per-mobility group basis. In one exemplary embodiment of the invention this is realized by only one of the mobile terminals in a mobility group sending a group location update on behalf of the group to trigger the location update for the mobility group. Alternatively, in another embodiment of the invention, a network operator trusted or controlled entity sends a group location update on behalf of the group to trigger the location update for the mobility group.

The REFER BYE message must include information, such as pre-established session parameter information, a session IDentifier (ID), etc. Also, the REFER BYE message is transmitted from the PoC client to the PoC server, and the PoC server receives the REFER BYE message, checks the contents of a header in the received message, and terminates the PoC session while keeping the pre-established session maintained when a specified condition is satisfied.

  • Patent number: 8284773
    Abstract: A method and system for establishing group multicast communication, such as PoC multicast communication. Multiple terminals will join a PoC multicast group automatically at some point before the underlying PoC session is being initiated and thus before there is any PoC content for a PoC server to multicast to the group members. Further, this joining process will occur without the PoC multicast channel being listed in the terminals' multicast channel listings. Thereafter, when one of the terminals opts to initiate the PoC session and thus signals to the PoC server, the server will cause the participating terminals to tune to the associated PoC multicast channel for the PoC multicast group that the terminals had already joined. The invention thereby helps to effectively randomize the timing of join-signaling by the various terminals and thus helps to conserve network resources.
