Patent ID: 8675582

Claim:
A method for setting up a Radio Bearer (RB), comprising: receiving a first RB setup message sent by an evolved NodeB (eNB); setting up, according to the first RB setup message, a first combined RB with the eNB with regard to a service request initiated by a first User Equipment (UE), when on a relay link there is no RB that bears a same service as an RB which is set up according to the service request initiated by the first UE; creating a mapping table between the first combined RB and RBs on an access link; generating a second RB setup message for the first UE; sending, according to the mapping table, the second RB setup message to the first UE, notifying the first UE to set up an RB on the access link; updating the mapping table when a third RB setup message is sent by the eNB when the eNB or a Core Network (CN) determines that a service required by a service request initiated by a second UE is the same as a service of the first combined RB; generating a fourth RB setup message for the second UE; and sending, according to the updated mapping table, the fourth RB setup message to the second UE, notifying the second UE to set up an RB on the access link.
