Problems solved by technology

[0003] The above service preemption scheme is for user equipment (User Equipment, UE). Since ordinary UEs only have primary cells, while carrier aggregation UEs have not only primary cells but also secondary cells, the above service preemption schemes cannot be applied to carrier aggregation UEs.
At present, there is no service preemption scheme for carrier aggregation UEs. If the existing service preemption scheme is adopted for carrier aggregation UEs, the success rate of E-UTRAN Radio Access Bearer (E-RAB) establishment will be reduced, and the Service drop rate, affecting user experience

Embodiment Construction

[0066] An embodiment of a service preemption method provided by the present invention, such as figure 1 As shown, the method includes:

[0067] Step 101, receiving a service request.

[0068] Step 102: When it is determined that the type of UE to which the service belongs is a carrier aggregation UE, split processing is performed on the E-RAB carried in the service request according to the obtained radio resource status information.

[0069] Here, the category of the UE to which the service belongs is divided into a common UE and the carrier aggregation UE, and the category of the cell to which the service belongs is divided into a primary cell and a secondary cell. There is only a primary cell for a common UE, and not only a primary cell but also a secondary cell for a carrier aggregation UE.

[0070] Step 103: Determine whether to access services according to the E-RAB acceptance result of the primary cell, the service preemption result of the primary cell, and the E-RAB e...

Abstract

A service preemption method, device, and nodeB. The method comprises: receiving a service request; when it is determined that the type of the user equipment belonging to the service is a carrier aggregation UE, disassembling, according to obtained wireless resources status information, the evolved universal terrestrial radio access network radio access bearer (E-UTRAN RAB, E-RAB) carried by the service request; determining, according to the E-RAB reception result of a primary cell, the primary cell service preemption result, and the result of establishing E-RAB of a secondary cell, whether to access the service, and responding to the service request; determining, according to the preemption service process result, whether to release preempted service.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a service preemption method, device and base station. Background technique [0002] For the Long Term Evolution (LTE) communication system, when a new service is requested, the evolved base station (Evolved Node B, eNB) of the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) Resource allocation is performed according to the priority information carried in the allocation reservation priority carried in the service request. If the resource is insufficient, it will be processed according to the preemption indication carried by the allocation reservation priority. If the preemption capability of the preemption indication is "can trigger preemption", a certain number of low-priority services whose preemption capability is "can be preempted" are selected from existing services to release resources so as to access...
