Abstract
A bearer allocation method, a User Equipment (UE), a base station, and a serving gateway are disclosed. The bearer allocation method includes: when a network entity creates a bearer for a UE, determining that the bearer has a bearer retain characteristic, and marking a bearer retain flag in bearer context information; and when the UE enters an IDLE state, an evolved base station and an SGW to which the UE belongs reserving the bearer context information marked with the bearer retain flag.
Claims13
A bearer allocation method, comprising:
- when a network entity creates a bearer for a User Equipment (UE), if it is determined that the bearer has a bearer retain characteristic, marking a bearer retain flag in bearer context information;
- and
- when the UE enters an IDLE state, an evolved base station and a Serving Gateway (SGW) to which the UE belongs reserving the bearer context information marked with the bearer retain flag;
- wherein
- when the UE is in the IDLE state, transmitting and/or receiving Internet Protocol (IP) data using the bearer having the bearer retain flag.
A base station comprising hardware for executing instructions stored in a non-transitory computer readable medium to execute steps in:
- a first module, configured to when a User Equipment (UE) enters an IDLE state, reserve context information of a radio access bearer marked with a bearer retain flag;
- and
- a second module, configured to when a Radio Resource Control (RRC) connection request which is initiated by the UE in an IDLE state is received, return radio access bearer information to the UE according to the reserved context information of the radio access bearer;
- wherein when the UE is in the IDLE state, the second module is configured to transmit and/or receive Internet Protocol (IP) data using the bearer having the bearer retain flag.
A Serving Gateway (SGW) comprising hardware for executing instructions stored in a non-transitory computer readable medium to execute steps in:
- a first module, configured to when a User Equipment (UE) enters an IDLE state, reserve context information of an Evolved Packet System (EPS) bearer marked with a bearer retain flag;
- and
- a second module, configured to when Internet Protocol (IP) data transmitted to the UE is received, if it is determined that the reserved bearer can be used to transmit the data, transmit the IP data to the UE through a base station using the bearer;
- wherein when the UE is in the IDLE state, the second module is configured to transmit and/or receive the IP data using the bearer having the bearer retain flag.
