    Abstract: 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.

    Abstract translation: 这些站点加入各自的位置区多播地址,以接收来自其位置区域中的其他站点的消息。 希望参与谈话组呼叫的通信单元只需要注册与位置区域的第一站点的联系。 在第一个站点接收到联属消息时,它加入一个有效载荷多播组地址以接收谈话组的有效载荷。 在替代实施例中,第一站点经由位置区域多播地址将与谈话组呼叫相关联的控制消息或隧道有效载荷发送到位置区域的辅助站点。 站点发起寻呼序列以确定其站点处的通信单元是否希望参与呼叫,并且基于响应,站点可以递送存储的有效载荷和/或加入有效载荷多播组地址以接收呼叫的有效载荷。

    Abstract: Techniques are provided for forming networks based on services offered or provided by particular leader nodes. Client nodes in the network can select a particular leader node based on a desired service offered or provided by the particular leader node. The client nodes can become a part of a different structured network such that the client nodes can have access to a desired service provided, either directly or indirectly, by the particular leader node.

    Abstract translation: 提供了基于由特定领导节点提供或提供的服务来形成网络的技术。 网络中的客户端节点可以基于由特定领导节点提供或提供的所需服务来选择特定的领导节点。 客户端节点可以成为不同结构化网络的一部分,使得客户端节点可以直接或间接地由特定的领导节点访问所需的服务。

    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: 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) o f 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. Bas ed on the multicast address, the site can participate in traffic targeted for t he multicast address and, consequently, for the talk group. In this manner, mobility processing is decentralized, system scalability is improved and cal l setup delays are minimized.
