    Abstract: A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203-208 that are in location areas 260, 261. The sites join respective location area multicast addresses to receive messages from other sites in their location area. Communication units desiring to participate in talkgroup calls need only to register affiliation with a first site of the location area. Upon the first site receiving an affiliation message, it joins a payload multicast group address to receive payload for the talkgroup. In alternative embodiments, the first site sends, via the location area multicast address, either control message(s) or tunneled payload associated with the talkgroup call to secondary site(s) of the location area. The sites initiate paging sequences to determine whether communication units at their sites desire to participate in the call and, based on the responses, the sites may deliver stored payload and/or join the payload multicast group address to receive payload for the call. In this manner, a centralized entity such as a VLR is not needed to keep track of communication units in the location area.

    Abstract: A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203–208. Upon a first communication unit (213) initiating a call request for a 2-party call with a second communication unit (215), a call server 235 identifies respective multicast IP addresses (MC1, MC2) associated with the source and target. If the first communication unit 213, or its associated site (205) desires to send payload to the second communication unit 215, it addresses the payload to the multicast IP address (MC2) of the second communication unit, and the second communication unit 215, or its associated site 206 joins the multicast address MC2 to receive the payload. Conversely, if the second communication unit 215, or its associated site (206) desires to send payload to the first communication unit 213, it addresses the payload to the multicast IP address (MC1) of the first communication unit, and the first communication unit 213, or its associated site 205 joins the multicast address MC1 to receive the payload.

    Abstract: A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203-208 that are in wireless communication with a plurality of subscriber units 210-217 logically arranged into a plurality of talk groups having corresponding talk group identifications. In one embodiment, each site maintains mappings 220-225 of at least one multicast address to at least one talk group identification. In another embodiment, individual subscriber units maintain such mappings 320. When a subscriber unit affiliates with a given site and talk group (501, 601), the site identifies a multicast address corresponding to the talk group. Based on the multicast address, the site can participate in traffic targeted for the multicast address and, consequently, for the talk group. In this manner, mobility Processing is decentralized, system calability is improved and call setup delays are minimized.

    Abstract: Generally speaking, pursuant to the various embodiments, pre-allocation of resources in a RAN of a communication system is performed. A system element having an application function determines, for a set of user equipment (UE), pre-allocation information used to select a set of cells in the RAN to which the set of UE will connect for exchanging data. The element sends a request to establish a bearer to an evolved packet core (EPC), wherein the request includes the pre-allocation information. The determining and sending actions are performed prior to one or more of the UE in the set of UE connecting to the set of cells. The EPC processes the request and returns a response to the system element, which identifies that a bearer for unicast and/or group communications has been established.

    Abstract: An infrastructure device in a 3GPP compliant system performs a method transporting a plurality of media streams over a shared MBMS bearer. The 3GPP compliant system includes a RAN partitioned into a plurality MBMS services areas, wherein each MBMS service area has at least one already existing shared MBMS bearers for transporting the media streams. The infrastructure device: receives a first request to transmit a first media stream to a first communication group; identifies a shared MBMS bearer in a first 3GPP MBMS service area that is already transporting a second media stream to a second communication group; and determines whether the shared MBMS bearer has sufficient capacity to transport both the first media stream and the second media stream simultaneously. When the shared MBMS bearer has sufficient capacity, the infrastructure device simultaneously sends both the first media stream and the second media stream on the shared MBMS bearer.
