Abstract
The present invention discloses a method for realizing a handoff by replicating topology, including: a MGW receiving an ADD Command from a MSCe, adding a new Termination to a Context, and establishing a bearer to a target office or a target base station; receiving a MODIFY Command from the MSCe, and modifying properties of the new Termination; and receiving a SUBTRACT Command from the MSCe, removing an original Termination, and according to recorded information about relationship between the new Termination and the original Termination carried by a Handover Package in one Command, playing the Tone of the original Termination to the new Termination continuously and establishing the same topology connection between the new Termination and other Terminations in the Context. The present invention also discloses a system for realizing a handoff by replicating topology, a media gate-way and a mobile switching center emulation. The present invention completes the topology replication.
