Abstract

When a representative PS server receives a P-TMSI contained in a PDP context succession request signal from a UE according to a handover communication procedure prescribed in an applicable standard after the UE moves, if the PS server identified with the identification information contained in the received P-TMSI is not its own representative PS server, the representative PS server identifies the PS server identified with the identification information as a PS server that manages a femtocell base station to which the UE belonged before it moved and forwards the PDP context succession request signal to the identified PS server.
