MOBILE COMMUNICATION SYSTEM, BASE STATION CONTROL DEVICE, MOBILE DEVICE, HANDOVER CONTROL METHOD, AND PROGRAM
摘要
The present invention provides a mobile communication system which can perform handover without deleting user data in an HSDPS system. In the handover in a mobile device 1, an RNC 4 makes a Node-B3 as a handover destination establish an HS-DSCH (step S213) to send the same user data respectively from the Node-B2 as a handover source and the Node-B3 as a handover destination to the mobile device 1 with the use of the HS-DSCH (steps S219 to S226). The mobile device 1 restores the user data on the basis of data which can be received before and after an HS-DSCH switching operation (step 5215).
