Radio bearer processing relating to suspending data transmission
Embodiments of the present invention provide a radio bearer processing method, user equipment, and a base station. The method includes: suspending, by user equipment, data transmission of a bearer on a second base station; and sending, by the user equipment, a suspend indication to a first base station, where the suspend indication is used to indicate that the user equipment has suspended the data transmission of the bearer on the second base station. When the data transmission of the bearer on the second base station is resumed, the related protocol entity does not need to be re-established, thereby improving utilization of radio bearer resources.
1. A radio bearer processing method, comprising:
receiving, by a first base station, a suspend indication sent by a user equipment, wherein the suspend indication is generated according to a first measurement result measured by the user equipment;
determining, by the first base station according to the suspend indication, that the user equipment has suspended data transmission with respect to a bearer on a second base station;
receiving, by the first base station, a plurality of second measurement results sent by the user equipment, wherein the plurality of second measurement results are results periodically obtained by measuring a quantity of data packets to be sent by the user equipment over the bearer;
determining, by the first base station, according to one or more of the second measurement results, that data transmission with respect to the bearer on the second base station needs to be resumed; and
sending, by the first base station, a resume command to the user equipment, and sending a second resume request to the second base station, wherein the resume command is for instructing the user equipment to resume data transmission with respect to the bearer on the second base station, and the second resume request is for requesting the second base station to resume data transmission with respect to the bearer on the second base station.
2. The method according to claim 1 , wherein the resume command is further for instructing the user equipment to re-establish a Radio Link Control entity (s-RLC) in the user equipment and resume the s-RLC, wherein the s-RLC is associated with the bearer and corresponds to the second base station.
3. The method according to claim 1 , wherein the second resume request is further for requesting the second base station to re-establish a Radio Link Control entity (ps-RLC) in the second base station and resume the ps-RLC, wherein the ps-RLC is associated with the bearer.
4. The method according to claim 1 , wherein the second resume request is further for requesting the second base station to reset a Media Access Control entity (ps-MAC) in the second base station, wherein the ps-MAC is associated with the bearer, and re-establish a Radio Link Control entity (ps-RLC) in the second base station and resume the ps-RLC, wherein the ps-RLC is associated with the bearer.
5. A first base station, comprising a processor and a non-transitory computer-readable medium having processor-executable instructions stored thereon, wherein the processor-executable instructions, when executed by the processor, facilitate:
receiving a suspend indication sent by a user equipment, wherein the suspend indication is generated according to a first measurement result measured by the user equipment;
determining, according to the suspend indication, that the user equipment has suspended data transmission with respect to a bearer on a second base station;
receiving a plurality of second measurement results sent by the user equipment, wherein the plurality of second measurement results are results periodically obtained by measuring a quantity of data packets to be sent by the user equipment over the bearer;
determining, according to one or more of the second measurement results, that data transmission with respect to the bearer on the second base station needs to be resumed; and
sending, by the first base station, a resume command to the user equipment, and sending a second resume request to the second base station, wherein the resume command is for instructing the user equipment to resume data transmission with respect to the bearer on the second base station, and the second resume request is for requesting the second base station to resume data transmission with respect to the bearer on the second base station.
6. The first base station according to claim 5 , wherein the resume command is further for instructing the user equipment to re-establish a Radio Link Control entity (s-RLC) in the user equipment and resume the s-RLC, wherein the s-RLC is associated with the bearer and corresponds to the second base station.
7. The first base station according to claim 5 , wherein the second resume request is further for requesting the second base station to re-establish a Radio Link Control entity (ps-RLC) in the second base station and resume the ps-RLC, wherein the ps-RLC is associated with the bearer.
8. The first base station according to claim 5 , wherein the second resume request is further for requesting the second base station to reset a Media Access Control entity (ps-MAC) in the second base station, wherein the ps-MAC is associated with the bearer, and re-establish a Radio Link Control entity (ps-RLC) in the second base station and resume the ps-RLC, wherein the ps-RLC is associated with the bearer.
