Claim Text:
1. A method for establishing a bearer supporting uplink Semi-Persistent Scheduling (SPS), comprising: parsing, by a Radio Resource Control (RRC) entity of a User Equipment (UE), an RRC connection reconfiguration message transmitted from an Evolved Node B (eNB) to obtain logic channel configuration information and Evolved Packet System (EPS) bearer activation request information, parsing the logic channel configuration information to obtain Radio Bearer Identifier (RBID) information and Logic Channel Group (LCG) information, transmitting the parsed logic channel configuration information to a Media Access Control (MAC) entity of the UE and transmitting the EPS bearer activation request information and the RBID information to a Non-Access Stratum (NAS) of the UE; establishing, by the MAC entity of the UE, a Logic Channel (LC) and a Logic Channel Group (LCG) between itself and a Radio Link Control (RLC) entity according to the received logic channel configuration information, and establishing a mapping between the RBID and the LCG; establishing, by the NAS of the UE, an EPS bearer between itself and an NAS of an Evolved Packet Core network (EPC) according to the received EPS bearer activation request information, and establishing correspondences between classifiers and LCs; parsing a Quality of service Class Identifier (QCI) from the EPS bearer activation request information, establishing a mapping between the parsed QCI and the received RBID, and transmitting the mapping to the MAC entity; and establishing, by the MAC entity, a mapping among the QCI, the RBID and the LCG according to the established mapping between the RBID and the LCG and to the mapping between the QCI and the RBID transmitted from the NAS.
