Claim:
1. A method for radio resource management, applied to a long-term evolution (LTE) system introduced with a source low power node (S-LPN) and a target low power node (T-LPN), comprises: a macro evolved node B selecting the S-LPN for an accessed user equipment to provide a joint transmission service; the S-LPN and the macro evolved node B jointly providing a radio resource management service for the user equipment; the S-LPN indicating to the T-LPN or the macro evolved node B the serial number of a distributed data packet successfully transmitted between the S-LPN and the user equipment; and the S-LPN forwarding to the T-LPN data packet received from the macro evolved node B, but not yet successfully received by the user equipment; wherein the user equipment accesses the T-LPN and establishes, together with the T-LPN, a signaling radio bearer.
