Embodiment Construction

[0031] Preferred embodiments of the present invention will be described herein with reference to the accompanying drawings. In the ensuing description, well-known functions and constructions are not described in detail since they would obscure the invention in unnecessary detail.

[0032] According to the present invention, the BSC and the BTS correspond not in a 1-to-N relationship, but in an N-to-M relationship. With such a relationship between BSC and BTS, the capacity load of RAN, the delay of handover, and the delay of service sending / receiving are reduced. The description that follows is optimally at least one BSC and at least two BTSs connected to the RAN.

[0033] Figure 5 It is a block diagram of a BSC in a mobile communication system with a planar structure according to an embodiment of the present invention. according to Figure 5 , the BSC is connected to the GW (gateway) and the BTS through the first interface 220 and the second interface 230 respectively. C...

Abstract

A handoff implementing method in a mobile communication system having a planar structure, in which at least two BSCs are connected to at least two BTSs through a RAN. An MT transmits a first Handoff Request message containing its information and information about its anchor BSC to a target BTS when it moves to a handoff zone. Upon receipt of the first Handoff Request message, the target BTS transmits a second Handoff Request message containing the MT information and its information to the anchor BSC. Upon receipt of the second Handoff Request message, the anchor BSC transmits a traffic signal directed to the MT to the target BTS.

Description

technical field [0001] The present invention generally relates to handover in a BTS (Base Transceiver System) in a mobile communication system, and more particularly, to a method for implementing handover in a mobile communication system having a planar structure. Background technique [0002] Generally, in a mobile communication system, an MT (Mobile Terminal) is connected to a BTS through a wireless link, and a BTS is connected to its higher layer through a wired link. Existing mobile communication systems and Internet connectivity for wider distribution of information such as Figure 1A with 1B shown. [0003] Figure 1A Shows the network configuration of a conventional mobile communication system. according to Figure 1A , a PDSN (Packet Data Serving Node) or AGW (Access Gateway) 20 interconnected with the Internet 10 is located at the highest layer. RAN-CN (Radio Access Network-Core Network) 30 is connected to PDSN / AGW 20 . BTS (Base Transceiver System) 60-1 to 60-m...
