Wireless communication system and method for performing handover in such a system |
摘要 |
The present invention relates to a method and apparatus for performing handover in a wireless communication system, and the handover method of the present invention includes checking, when a Path Switch Request message associated with a terminal is received from a base station, whether a list of terminal security information values which has been saved exists; generating, when the list exists, a Path Switch Request acknowledge message including an unused terminal security information value selected form the list; and transmitting the Path Switch Request acknowledge message to the base station. Through this procedure, it is possible to reduce the terminal handover signal load generated by the base station. |

1. A handover management method of a base station gateway processing signals between a mobility management entity and base stations, the handover management method comprising:
checking, when a Path Switch Request message associated with a terminal is received from a base station, whether a list of terminal security information values which has been saved exists; generating, when the list exists, a Path Switch Request acknowledge message including an unused terminal security information value selected from the list; and transmitting the Path Switch Request acknowledge message to the base station. |
