DATA TRANSFER MANAGEMENT IN A RADIO COMMUNICATIONS NETWORK
First Claim
1. A method of performing a data transfer management in a wireless communications system, the method comprising:
- receiving, by a mobile terminal from a source base station, a handover command to perform a handover,wherein the handover command includes the identification information comprises a new Cell-Radio Network Temporary Identifier (C-RNTI) of the mobile terminal;
sending, by the mobile terminal to a target base station, synchronization information for accessing into the target base station; and
receiving, by the mobile terminal from the target base station, uplink allocation resources and timing advance information for the mobile terminal.sending, by the mobile terminal to the target base station, a handover confirm message after receiving the uplink allocation resources and the timing advance information;
transmitting, by the mobile terminal, first status information to the target base station; and
receiving, by the mobile terminal, second status information from the target base station,wherein the first status information relates to user data that has been properly or not properly received by the mobile terminal, and the second status information relates to user data that has been properly or not properly received by the target base station.
