    • 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.
    • 无线通信系统200包括耦合到位置区域260,261中的多个站点203-208的无连接分组网络201.站点加入相应的位置区域多播地址以从其位置区域中的其他站点接收消息。 希望参加谈话组呼叫的通信单元仅需要注册与位置区域的第一个站点的归属。 在第一站点接收到附属消息时,它加入有效载荷多播组地址以接收该通话组的有效载荷。 在替代实施例中,第一站点经由位置区域多播地址将与通话组呼叫相关联的控制消息或隧道传输的有效载荷发送到位置区域的次要站点。 站点启动寻呼序列以确定其站点上的通信单元是否希望参与呼叫,并且基于响应,站点可传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。 以这种方式,不需要诸如VLR的集中实体来跟踪位置区域中的通信单元。

    • In a wireless ad hoc network comprising a plurality of nodes (102), when a method of the present invention determines that a source node and a destination node belong to a common virtual local area network (VLAN), information is routed to the destination node using only nodes that belong to the common VLAN. If a path is not available to route the information between the source node and the destination node using only nodes that belong to the common VLAN, a default VLAN is used to route the information at least partially through the ad hoc network. If, however, the method of the present invention determines that the source node belongs to a first VLAN and the destination node belongs to a second VLAN, the source node or an intermediate node registers with the second VLAN and continues routing the information using nodes that belong to the second VLAN.
    • 在包括多个节点(102)的无线自组织网络中,当本发明的方法确定源节点和目的地节点属于公共虚拟局域网(VLAN)时,信息被路由到目的地节点 仅使用属于公共VLAN的节点。 如果路径不可用于使用属于公共VLAN的节点在源节点和目标节点之间路由信息,则使用默认VLAN至少部分地通过自组织网络路由信息。 然而,如果本发明的方法确定源节点属于第一VLAN并且目标节点属于第二VLAN,则源节点或中间节点向第二VLAN注册,并使用节点继续路由信息 属于第二个VLAN。
