Problems solved by technology

[0004] However, if the UE performs a radio link failure (Radio Link Failure, RLF), or handover, or moves away from the neighbor cell to be measured during the measurement process of the neighboring cell global cell identity (CGI), it will cause CGI Measurement failed
If the correct and complete neighbor relationship cannot be obtained after multiple measurements over a long period of time, the handover success rate will decrease and the continuous coverage of the network cannot be guaranteed.
[0005] In addition, the UE cannot process service data during the process of performing neighboring cell global cell identity (CGI) measurement, which will also affect the quality of service (QoS) experience of the service

Abstract

The invention discloses an automatic neighbor relation (ANR) measurement method and an apparatus thereof. The method and the apparatus are used to select appropriate user equipment (UE) to carry out cell global identity (CGI) measurement. Therefore, under the condition that a QoS feeling degree and network performance are not affected, an ANR measurement success probability can be increased. The ANR measurement method provided in the invention comprises the following steps: determining the UE which satisfies a CGI measurement condition as target UE; sending neighbor CGI measurement control information to the target UE; updating a neighbor relation table through the neighbor CGI and a neighbor physical cell identity (PCI) reported by the target UE.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an automatic neighbor relation (Automatic Neighbor Relation, ANR) measurement method and device. Background technique [0002] Automatic Neighbor Relation (ANR) is an important function of Self-Organizing and Self-Optimization Network (SON) technology. Different from the traditional method of mainly relying on network engineers to configure and adjust according to on-site survey conditions, the introduction of the automatic neighbor relationship function can trigger the base station to start measurement, collect data, and generate Alarms and handling suggestions to optimize the relationship between neighbors. The intermediate process of this processing is carried out automatically, so the labor cost can be greatly reduced. [0003] The automatic neighbor relation ANR function is assisted by user equipment (User Equipment, UE). see figure 1 , the ANR measureme...
