Abstract: A method for transmitting data in a single-frequency network in a Long Term Evolution (LTE) network includes receiving media for broadcast in a broadcast area of a plurality of broadcast areas associated with a single-frequency network, wherein the broadcast area comprises a plurality of cells; identifying a subset of defined broadcast resources for broadcasting the media to the broadcast area; broadcasting the media to the broadcast area using the subset of defined broadcast resources; and broadcasting a null pattern on the subset of defined broadcast resources in adjacent broadcast areas to the broadcast area. An associated LTE network and broadcast controller are also described.

Abstract: A method for transmitting data from a participant device in a session in an Internet Protocol (IP) system (100) is provided. The method comprises sending (405) one or more a first Real-time Transport Protocol (RTP) packet of the session to a first address. The method further comprises sending (410) one or more a first Real-time Transport Control Protocol (RTCP) packet of the session to a second address. The participant device sends the one or more a first RTP packet and the one or more a first RTCP packet.

Abstract: In the present technique, a dispatch call setup determines (508) whether an auto-reply as a response to a polite dispatch call request is available. If so, a dispatch call blocked using the available auto-reply is sent (512) as a response to the polite dispatch call request. In response to an impolite dispatch call request being received (504, 506), a determination (528) occurs regarding whether an impolite request is allowed, and if not, the impolite dispatch call request is rejected (522). Otherwise, a dispatch call page is sent (534) to indicate the impolite dispatch call request.

Abstract: A wireless communication device facilitated by a network controller and corresponding methods select a list of requested groups for affiliation from a list of associated groups. The list of requested groups is sent to a network infrastructure where it is processed according to a set of rules. A final list of groups for affiliation is made and the network infrastructure is configured to support the affiliated groups. The list of affiliated groups may also be sent to the wireless communication device.

Abstract: A method (600,700) and apparatus (800) are arranged and operate for facilitating call routing between sites in an enterprise connected by a private IP network (130). A range of identifiers (220-223) served by IP PBXs (120-123) in the enterprise may be registered with a SIP registrar (212) of an inter-site router (210). Call requests to a communication unit (350) outside the home site are routed to the SIP registrar. A site identifier associated with the destination IP PBX allows the call to be completed by the SIP Proxy or the IP PBX where the call was received. When no private IP network is available, a roaming CU registers with a cellular proxy in the visited network. Calls are routed by when an HLR (340) associated with the CU obtains the roaming number from the cellular proxy (330) in the visited site. The MSC completes the call to the visited IP PBX using the roaming number and a local SIP registrar 440 forwards the call to the CU.

Abstract: An access point (102) conveys (202) to communication units (104) of a plurality of multicast groups, a first indication that the access point supports a method for sending a multicast message. The access point receives (204) a multicast message directed to a receiving one of the plurality of multicast groups, and determines (206) that the communication units belonging to the receiving one of the plurality of multicast groups also support the method. The access point signals (208) a second indication to selectively awaken the communication units belonging to the receiving one of the plurality of multicast groups, and transmits (210) the multicast message to the receiving one of the plurality of multicast groups in a manner that allows (212) at least one communication unit not belonging to the receiving one of the plurality of multicast groups to remain asleep during the transmitting.
