Method, communication system, and source base station for realizing inclination base station in lte system

Abstract

The present invention relates to a method, a communication system, and a source base station for realizing leaning base stations in an LTE system, including: when a user equipment is covered by a source base station and a target base station at the same time, and the user equipment detects that the signal strength of the source base station is greater than that of the target base station, the user equipment starts from When the source base station accesses and the target PLMN of the user equipment is the target base station, the following steps are performed: S1. The core network confirms that the user equipment is not accessed from the target base station; S2. The core network sends identification information identifying the user equipment and the target base station to the source Base station; S3. The source base station receives the identification information, and switches the user equipment to access the target base station according to the identification information. By implementing the present invention, a method is provided in which the system controls the switching of preferred base stations of user equipment in the LTE system, without modifying the protocol stack of user equipment, without modifying the chip of user equipment, and reducing the dependence on user equipment in the selection process of preferred base stations .

Description

technical field [0001] The present invention relates to the field of wireless communication, and more specifically, relates to a method for realizing a preferred base station in an LTE system, a communication system and a source base station. Background technique [0002] In the private network requirements, there is a scenario such as a police system in a certain place. For safety, the terminals under it need to select the target of the police system within the coverage of multiple PLMNs (Public Land Mobile Networks, that is, public land mobile networks). The PLMN is accessed through a suitable base station. At present, the narrowband technology means that the terminal needs to choose which base stations to access according to the needs, rather than being determined by the system, which has certain restrictions on the terminal and lacks flexibility. In a broadband system, all behaviors of LTE terminals are controlled by the system, and they cannot independently choose whic...
