Embodiment Construction

[0077] When a UE in a connected state with EN-DC capability is handed over from the first cell to the second cell, in order to prevent the target base station in charge of the second cell from being unable to use NR resources to provide services for the UE because it cannot know the EN-DC capability of the UE In the embodiment of the present invention, after the UE completes the above handover, the target base station will detect the EN-DC capability of the first cell, and when it is determined that the first cell does not have the EN-DC capability, it will actively obtain the EN-DC capability of the UE from the UE. -DC capability, and configure the secondary base station (ie SgNB) for the UE according to the EN-DC capability of the UE.

[0078] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0079] refer to Figure 4 As shown, the embodiment of the present invention particularly rel...

Abstract

The invention relates to the field of communication, in particular to a cell configuration method and device based on NSA, and aims to solve the problem that service cannot be provided for UE by usingNR resources due to the fact that the 5G network access capability of the UE cannot be obtained. The method comprises the following steps: when a target base station serving as a main base station determines that UE is switched from a first cell to a second cell managed by the target base station, actively querying the EN-DC capability of the UE if that the first cell does not have the EN-DC capability is determined; when that the UE has the EN-DC capability is determined, configuring an NSA cell working in a 5G network and a corresponding auxiliary base station for UE. Thus, the UE can use the corresponding service through the 4G network and the 5G network, thereby effectively reducing the resource load of the main base station, fully utilizing the 5G network resource, improving the cellthroughput, remarkably improving the service rate of the UE, and improving the user satisfaction.

Description

technical field [0001] The present invention relates to the communication field, in particular to an NSA-based cell configuration method and device. Background technique [0002] Currently, two networking schemes, Non-Stand Alone (NSA) and StandAlone (SA), are introduced into the 5G standard. As a transitional solution, non-standalone networking aims to increase bandwidth in hotspot areas. In non-standalone networking, 5G base stations do not have an independent signaling plane and rely on 4G base stations and 4G core networks to work. The independent networking can realize all the new features of 5G, which is conducive to giving full play to the full capabilities of 5G. It is a 5G target solution recognized by the industry. [0003] However, in the initial stage of 5G network construction, due to practical issues such as technical capabilities and equipment costs, non-independent networking solutions are temporarily used to build 5G networks. The non-independent networkin...
