Problems solved by technology

However, under the 3C architecture, there is no S1 interface between SeNB and MME (that is, information exchange cannot be performed directly). When the EPS bearer needs to be released, the MME cannot send a bearer release request to SeNB according to the existing LTE system bearer release process. Complete the DRB release between SeNB and UE

Abstract

The invention discloses a method of releasing a radio bearer in a dual-connection network and a system, which relates to the technical field of radio communication. The problem of releasing a DRB (Data Radio Bearer) between a SeNB and UE in the dual-connection network by adopting a 3C frame can be solved. In certain trigger conditions, a MeNB can initiate a DRB releasing process between the SeNB and the UE, the realization method is simple, advantages of the dual-connection technology are used thoroughly, and normal service transmission of the user can be ensured.

Description

technical field The present invention relates to the technical field of wireless communication, in particular to a method and system for releasing a wireless bearer in a dual connectivity network. Background technique Dual connectivity network is a research hotspot in current wireless communication technology, and the network architecture is shown in Figure 1. In this network, the user terminal (UE) maintains an air interface connection with the macro base station (MeNB) and the micro base station (SeNB), which means that the macro base station and the micro base station can provide services for the UE at the same time. By using dual connectivity communication, when the UE moves inside the macro cell and enters or leaves a small cell, the handover process may not be performed, but the macro base station uses the resource reconfiguration process to configure or release small cell resources for the UE. The relevant control process executed by the core network will be greatly...
