Bearer establishing method and system based on handover
First Claim
1. A bearer establishing method based on handover, used for a target base station to establish a bearer for a user equipment, UE, when the UE is handed over from a source base station to the target base station, comprising:
- the source base station initiating a handover required message to a mobile management entity, MME, to request to hand over to the target base station;
the MME transmitting the handover required message to the target base station, and carrying bearer establishment information and aggregate maximum bit rate information, namely AMBR information, of the UE in the handover required message; and
the target base station establishing one or more bearers, wherein sum of bandwidth of Non-Guaranteed Bit Rate bearers is no greater than value of the AMBR information.

Abstract
The present invention discloses a bearer establishing method and system based on handover, wherein the method comprises: an MME transmits the handover required message to the target base station, and carries aggregate maximum bit rate information, namely AMBR information of the UE in the handover required message. In virtue of the above technical scheme, the AMBR information is transmitted to the target base station through the interface S1-MME from the MME when the handover through the MME happens, so that the target base station can obtain the AMBR information and achieve the establishment of the bearers.

3. A bearer establishing system based on handover, comprising:
-
a source base station, wherein the source base station is configured to initiate a handover required message to a mobile management entity, MME, to request to hand over a user equipment from the source base station to a target base station; the target base station; and the mobile management entity, MME, wherein the MME is configured to forward the handover required message transmitted from the source base station to the target base station, and to carry bearer establishment information and aggregate maximum bit rate information, namely AMBR information, of the UE in the handover required message; wherein the target base station is configured to establish one or more bearers, wherein sum of bandwidth of Non-Guaranteed Bit Rate bearers is no greater than value of the AMBR information. - View Dependent Claims (4, 8, 9, 10, 11)
