Abstract
The present invention discloses a method for carrying out a handover process in a wireless network, wherein the wireless network comprises at least a first and a second base stations belonging each to a different subnet associated of that wireless network and communicating through a first and a second gateways or foreign agents, respectively, and wherein the first base station is used as a serving base station currently in communication with at least one mobile subscriber station (MS). The method provided comprises a step of determining a traffic conveying entity as an intermediate anchoring point, and when the MS moves to a second subnet which comprises the second base station, a path is established for conveying traffic to/from that MS from/to a remote destination. The path comprises the intermediate anchoring point and the first gateway (or the first foreign agent).
