Abstract

The invention provides a method, apparatus and base station for switching a terminal device to a target cell. The method includes the steps of acquiring the type identifier of the terminal device and the information of a private network connected to an adjacent base station of a source base station to which the terminal device is accessed; and when the terminal device performs cell switching, switching to a target cell supporting the characteristics of the target private network corresponding to the type identifier according to the type identifier and the information of the private network connected to the adjacent base station. The source base station selects a target cell capable of supporting the characteristics of the target private network of the terminal device according to the type identifier of the private network supported by the terminal device and the information of the private network connected to the adjacent base station of the source base station, thereby controlling the terminal device to access the target cell. In this way, the terminal device can accurately access to the private network, thus avoiding redirection and other operations after switching. Realization is simple, the interaction process between a terminal device and the network is simplified, and the switching efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and base station for switching terminal equipment to a target cell. Background technique [0002] With the extensive use of machine-type communication (MTC), the network needs to face the problem of a large number of terminals accessing the network. At the same time, different terminals have different characteristics, and the supported services are diversified; for example, MTC such as vending machines may not need to support mobility , MTC such as medical monitoring needs to ensure real-time transmission of data, while MTC equipment such as water meters and electric meters only need to transmit small data at a specific time. In order to avoid the impact of these MTC devices on the services of existing users, and to provide appropriate optimization services for different user networks, operators may choose to deploy different types of core networks...
