Method and system for establishing bearer supporting uplink semi-persistent scheduling and user equipment thereof

Abstract

Disclosed are a method and system for establishing a bearer supporting uplink Semi-Persistent Scheduling (SPS) and a User Equipment (UE) thereof, and the method includes: an RRC entity of a UE parses an RRC connection reconfiguration message transmitted from an eNB to obtain logic channel configuration information, EPS bearer activation request information and RBID information, transmits the logic channel configuration information to an MAC entity of the UE and transmits the EPS bearer activation request information and the RBID information to an NAS of the UE; the MAC entity of the UE establishes an LC and an LCG between itself and an RLC entity according to the received logic channel configuration information, and establishes a mapping between the RBID and the LCG; the NAS of the UE establishes an EPS bearer between itself and an NAS of an EPC according to the received EPS bearer activation request information, and establishes correspondences between classifiers and LCs; and parses a QCI and the RBID from the EPS bearer activation request information, establishes a mapping between the parsed QCI and the received RBID, and transmits the mapping to the MAC entity. The present disclosure enables a UE to identify LCGs that can be scheduled by SPS, thereby using efficiently uplink SPS resource and improving quality of uplink services scheduling.
