Abstract: A method and apparatus for reducing latency in a group communication network (100) provides for a significant reduction in the actual total dormancy wake up time and the PTT latency by exchanging group call signaling even when mobile s (102, 104, 106) are dormant and no traffic channel is active. The method and apparatus provides for exchanging the group call signaling through the use o f the short data burst (SBD) message signaling. The method and apparatus provides for re-establishing dedicated traffic channels for the talker mobil e and the dormant listener mobiles advantageously in parallel.

Abstract: A method and apparatus for providing an efficient dormant mode for push-to- talk communication devices (102, 104, 106) in a group communication network (100) provides for determining whether the communication device has been inactive for a predetermined first time period and, if so, causing the communication device to enter a control-hold mode, wherein the communication device maintains its dedicated traffic channel. The method further includes the steps of determining whether the communication device has been in the control-hold mode for a predetermined second time period and, if so, causing the communication device to enter a dormant mode, wherein the communication device releases its dedicated traffic channel. The method and apparatus further provides for causing the communication device to cache its service configuration state before entering the dormant mode.

Abstract: A method and apparatus provides for delivering information to an idle mobile station in a group communication network (100) includes delivering the information to the mobile station in special form, e.g., short data burst (SDB) form, if the information is smaller than a predetermined size limit. I n one embodiment, the method and apparatus provides for encapsulating the information inside a frame, forwarding the frame to a server (110) for delivery to the mobile station (102, 104, 106), and causing the server (110) to extract the information from the frame and deliver the information to the mobile station on a forward common channel. In one embodiment, the method an d apparatus provides for receiving information for delivery to the mobile station (102, 104, 106), the information being tagged for delivery on a forward common channel, and delivering the information to the mobile station (102, 104, 106) on the forward common channel. In one aspect, the method delivers the information when the mobile station (102, 104, 106) is in idle state with no traffic channel.

Abstract: A system and method for providing group communication services. Each of a plurality of communication devices coverts information signals into data packets suitable for transmission over a data network, such as the Internet. The data packets are transmitted through the data network to a communications manager. The communications manager acts as a configurable switch, allowing communications from any communication device to be routed to the plurality of communication devices. The communications manager further allows users of other communication systems and devices to participate in group communications with each other.

Abstract: The disclosure is directed to prioritizing call announce response in a broadcast / multicast communication system. An embodiment establishes a first priority (810; 910) for response based on assigning each user equipment (UE) (120; 520; 522; 1000) a first random delay for response to a first call announce (740) responds to the first call announce using the first random delay and determines a second priority (820; 920; 930; 940) for response to a subsequent call announce based on an elapsed time that each UE is present in a multicast area.

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: 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: A method and apparatus for adding a member to an active call in a group communication network provides for receiving a member list from a user and sending a request to a server to add the member list to the active group call. The method and apparatus further provides for announcing each member in the member list that they are being added to the group call, receiving acknowledgement from a member who wishes to participate in the group call, and forwarding media to the member. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active.
