Abstract  Abstract

This invention claims a base station synchronization method and device for handover in a hybrid GSM/CDMA network. A mobile wireless communication system includes a base station (30) taking a first type operation according to a first air interface and a base station (36) taking a second type operation according to a second air interface. The method and apparatus are provided for handing over a mobile station (40) in the system from a first base station (30) of the first type to a second base station (36) of the second type. A communication link is established over the first air interface between the mobile station (40) and the first base station (30). Data is received from the mobile station in response to a signal received by the mobile station (40) over the second air interface from the second base station (36) substantially without breaking the communication link with the first base station. The mobile station (40) is handed over from the first base station (30) to the second base station (36) in response to the data received from the mobile station (40).
