发明名称 Updating multicast group information of a client device of a wireless mesh network
摘要 Systems, methods and apparatuses for updating multicast group information of a client device of a wireless mesh network are disclosed. One method includes an access node of the wireless mesh network determining multicast group information of the client device that is connected to the access node, and the access node providing routing updates to upstream access nodes and a first upstream gateway, wherein the multicast group information of the client device is included within the routing updates of the client device.

主权项 1. A method of updating multicast group information of a client device of a wireless mesh network, comprising: an access node of the wireless mesh network determining multicast group information of the client device that is connected to the access node; and the access node providing routing updates to upstream access nodes and a first upstream gateway, wherein the multicast group information of the client device is included within the routing updates of the client device; the first upstream gateway sharing the multicast group information of the client device with neighboring gateways; the first upstream gateway deleting multicast and unicast information of the client device if the client device roams to a second gateway; and the second gateway accessing the multicast group information of the client device when the client device roams to the second gateway; wherein if the second gateway cannot obtain the multicast group information of the client device from the first upstream gateway or from one of neighboring gateways, the second gateway broadcasting over an upstream interface a request for the multicast group information of the client device.
