Enhancement method and terminal equipment of ad hoc network

Abstract

The invention provides an ad hoc network enhancement method and terminal equipment. The method includes: when the wireless link fails, the handover fails, or the radio resource control connection fails to be established, the terminal judges whether there is coexistence interference; and determines whether to send ad hoc network information to the base station based on the judgment result. The terminal device includes a determination unit, configured to: determine whether there is coexistence interference when the radio link fails, the handover fails, or the radio resource control connection fails to be established; and based on the determination result, determine whether to send ad hoc network information to the base station. The method and terminal equipment provided by the present invention improve the ad hoc network by considering the influence of coexistence interference on wireless link failure information in wireless link failure and handover failure scenarios and access measurement information in radio resource control connection establishment failure scenarios. The reliability of relevant information enhances the quality of the ad hoc network.

Description

technical field [0001] The invention relates to the communication field, in particular to an ad hoc network enhancement method and terminal equipment. Background technique [0002] In the self-organizing network (Self-Organizing Network, SON) technology in the long-term evolution (Long Term Evolution, LTE) communication system, the terminal (User Equipment, UE) needs to record some SON-related information, including minimization of drive test (Minimization of Drive Test, MDT) information, radio link failure (Radio LinkFailure, RLF) and handover failure (Handover Failure, HOF) RLF information in scenarios, and radio resource control (Radio Resource Control, RRC) connection establishment failure scenarios Input measurement information and report to the base station. Specifically, the SON-related information includes serving cell information, same-frequency, different-frequency and different-system adjacent cell measurement information, location information, time information, ...

AI Technical Summary

Problems solved by technology

[0003] However, when a UE supports multiple radio access technologies, and these radio access technologies in the same UE use a single radio frequency design to send and receive data at the same time, interference between multiple radio access technologies is inevitable, that is, the so-called Coexistence (In-Device Coexistence, IDC) interference

IDC interference will affect the SON-related information collected by the UE, such as Reference Signal Received Power (Reference Signal Receiving Power, RSRP) and Reference Signal Received Quality (Reference Signal Receiving Quality, RSRQ) measurement values, etc., resulting in information pollution

Once the base station uses these inaccurate information to evaluate network coverage and performance, it will lead to wrong diagnostic conclusions and optimization measures

In the prior art, there is only a solution to enhance SON by considering the impact of IDC interference on MDT measurement information, but the RLF information in the RLF and HOF scenarios, and the access measurement information in the RRC connection establishment failure scenario have not been considered. The impact of IDC interference on them
