A BASE STATION OF WIDEBAND WIRELESS ACCESS SYSTEM AND A METHOD FOR REALIZING GROUP-BROADCAST SERVICE

摘要

A base station (BS) of wideband wireless access system includes: message obtaining module used for obtaining the group-broadcast protocol message between user station and router; group-broadcast address forwarding list maintaining module used for maintaining group-broadcast address forwarding list according to the type of obtained message; establishing group-broadcast module used for distributing same connection sign for all the user stations in the group-broadcast group, and managing the said user stations n the group-broadcast group according to the connection sign and maintained group-broadcast address forwarding list. A method for realizing group-broadcast service in wideband wireless access system includes the following steps: obtaining the group-broadcast protocol message between user station and router and maintaining group-broadcast address forwarding list according to the type of obtained message; distributing same connection sign for all the user stations in the group-broadcast group and managing the said user stations n the group-broadcast group according to the connection sign and maintained group-broadcast address forwarding list. Both the BS and the method provided in the invention can save bandwidth resource in the air.
