Abstract: A method performed by a first BS in a network, for discovering an address of a second BS in the network via a network node in the network, the method comprising: sending, to the network node, an address request message which includes a first list with one or more pairs of an address of the first BS and a corresponding sharing identifier; and receiving, from the network node, an address response message which includes a second list with one or more pairs of an address of the second BS and a corresponding sharing identifier. In the case of network sharing, by using the addresses and the corresponding sharing identifiers obtained through the method, the connectivity between the two BSs and ACL functionality at the two BSs specific to a particular upper network and/or operator may be achieved.

Abstract: An inter-network handoff system and method are disclosed, and include determining, by a setting BS, whether or not there exists a pilot stronger than a threshold value according to a PSMM received from a mobile station (MS), selecting a BS of which pilot is stronger than the threshold value as a target BS, determining whether or not the MS can accommodate a packet data service provided by the target BS, configuring the MS so as to accommodate the packet data service of the target BS, starting communication between the MS and the target BS, and terminating communication between the MS and the serving BS. Accordingly, a soft handoff can be performed between two systems having different data rates.
