Method, device and network for base station controller multi-homing in cdma2000

A Base Station Controller (BSC) for implementing multi-homing in CDMA2000, comprising:

• an air interface message transceiver unit configured to receive and transmit air interface messages;
• a processing unit configured to process air interface messages;
• a plurality of Mobile Switching Center (MSC) interfacing units configured to interchange information with the plurality of MSCs;
• and
• a mobile subscriber/MSC mapping relationship setting unit configured to set mapping relationships between mobile subscribers and MSCs;
• wherein
• the mobile subscriber/MSC mapping relationship setting unit acquires the MSC corresponding to the mobile subscriber according to a mobile subscriber identity carried in the air interface message acquired by the processing unit, and a corresponding MSC interfacing unit interchanges information with the MSC.
