Description

Network access method and device

The present application claims priority to Chinese Patent Application No. 201610380289.3, entitled "A Network Access Method and Apparatus", filed on May 31, 2016, the entire contents of in.

Technical field

The present invention relates to the field of network technologies, and in particular, to a network access method and apparatus.

Background technique

With the increase of mobile terminals and the diversification of user services, the demand for capacity of mobile communication networks will become larger and larger in the future. Simple cellular networks or wireless local area networks (WLANs) cannot meet the demand. The industry proposes an open wireless network architecture. (Open Wireless Architecture, OWA) technology, which integrates all wireless (and even wired) technologies and networks, and integrates various access networks to provide unified access and consistent use experience for terminals. In the OWA multi-network unified control mode, how to let users choose the appropriate access network and achieve a good user experience requires a unified control mechanism.

The terminal equipment (UE) in the fourth-generation mobile communication system (LTE) is divided into two states RRC-connected state and RRC_Idle; when the UE is in the RRC-connected state, the UE is currently connected. The base station (BS) can configure the UE to perform measurement reporting, thereby supporting mobility control of the UE and implementing access network switching. Specific implementations include:

First, the BS sends the measurement configuration to the UE; wherein the measurement configuration may include a measurement object (such as the measured cell list and associated parameters, such as carrier frequency and offset, etc.), criteria reported by the UE, measurement gaps, and the like;

The UE obtains a measurement report according to the measurement configuration, and reports the measurement report to the BS;

The BS determines, according to the measurement report reported by the UE, whether to control the UE to perform access network handover.

As shown in FIG. 1, if the BS determines to switch the UE from the source cell to the neighboring target cell according to the measurement report; the target cell and the source cell belong to different BSs but belong to the same Mobility Management Entity (MME). For example, the source BS to which the source cell belongs sends a handover request to the target BS to which the target cell belongs, and carries the current service information of the UE in the handover request; the target BS performs admission control and radio resource configuration according to the received UE service information. After the handover confirmation message is sent to the source BS, the message includes the admission result and the radio resource configuration information; the source BS forwards the handover confirmation message to the UE, and commands the UE to perform handover, and the UE completes the handover according to the radio resource configuration information on the target BS. Access.

In the OWA multi-network unified control mode, if the access network switching method is used, and the cell with the best signal quality is selected according to the measurement report, the UE needs to report and report all the networks at the same time, which wastes a lot of power resources and signaling.
