Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and It can be practiced, but the examples given are not to limit the invention. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0028] When a cell supports multiple coverage scenarios, the cell notifies the ID of the current coverage scenario to the user equipment (User Equipment, UE), for example, through system information broadcast to all UEs, or through radio resource control (Radio Resource Control, RRC) Send a configuration message to a certain UE, etc., to improve the accuracy of MRO problem detection and statisti...

Abstract

Disclosed are a mobility robustness method under multi-coverage scenarios, a base station and a terminal. The method comprises: a base station receiving a message, with the message carrying an identification(s) of one or more cells and a coverage scenario identification corresponding to a cell; the base station counting and analysing a problem of mobility robustness optimization (MRO) under different coverage scenarios by cell according to the cell identification and the coverage scenario identification which are carried in the message; and when a statistical analysis result of the coverage scenario designated by the cell meets a mobility parameter adjustment condition, the base station triggering the adjustment of the corresponding mobility parameter.

Description

technical field [0001] The present invention relates to the communication field, in particular to a mobile robustness optimization method, device and system when a cell supports multiple coverage scenarios. Background technique [0002] In order to reduce manual intervention on the network, reduce operation and maintenance costs, and improve network performance and stability, the Third Generation Partnership Projects (Third Generation Partnership Projects, 3GPP) organized Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio The Access Network (E-UTRAN) system began to introduce the self-organized network (Self-Organized Network, SON) function. E-UTRAN includes an evolved base station (evolved Node B, eNB), and its corresponding core network (Core Network, CN) includes a mobile management entity (Mobile Management Entity, MME) and a serving gateway (Serving Gateway, S-GW). The eNB and CN are connected through the S1 interface, and the eNBs ...
