摘要： A wireless device and method for managing a multicast group within a wireless network are disclosed. The wireless device is included in a first multicast group in which data is directly sent between member devices or data is sent using hopping between the member devices. The wireless device includes a reception unit, a determination unit, and a transmission unit. The reception unit receives a join request for joining a second multicast group from a joining device that attempts to join the second multicast group. The determination unit extracts information about the second multicast group from the join request, and determines whether the second multicast group is identical with the first multicast group based on the information about the second multicast group. The transmission unit forwards the join request to another device or sends a response to the join request to the joining device based on a result of the determination.

摘要翻译： 公开了一种用于管理无线网络内的组播组的无线设备和方法。 无线设备被包括在第一组播组中，其中在成员设备之间直接发送数据，或者使用成员设备之间的跳跃来发送数据。 无线设备包括接收单元，确定单元和传输单元。 接收单元从尝试加入第二组播组的加入设备接收加入第二组播组的加入请求。 确定单元从加入请求中提取关于第二多播组的信息，并且基于关于第二多播组的信息来确定第二多播组是否与第一多播组相同。 发送单元将加入请求转发到另一设备，或者基于确定的结果向加入设备发送对加入请求的响应。
