NETWORK-ASSISTED MOBILITY MANAGEMENT USING MULTIPLE RADIO ACCESS TECHNOLOGIES

摘要

Technology for a cellular base station (BS) in a multiple radio access technology (multi-RAT) heterogeneous network (HetNet) to communicate with a virtual access network (VAN) client is described. A desired VAN server can be determined from a plurality of VAN servers for a VAN client to communicate with. A VAN client that the VAN server is in communication with is determined. A VAN server notification is sent to the VAN client when the VAN client is in communication with a different VAN server than the desired VAN server.
