A system and method for locating a cell generating a paging black hole in a wireless network

Abstract

The invention discloses a method and a system for locating a cell in which a paging black hole occurs in a wireless network. The system includes: a signaling collection subsystem, which is used to collect signaling statistical information of the A interface and signaling measurement information of the ABIS interface and Send to the paging black hole cell positioning subsystem; the paging black hole cell positioning subsystem includes: a paging failure message extraction module, which is used to obtain the signaling statistical information of the A interface, and extract the paging black hole event that does not respond to paging The network event retrieval module is used to obtain the paging black hole event that does not respond to the paging, and retrieve the closest time from the paging black hole event in the signaling measurement information of the ABIS interface according to the paging black hole event A user network event; a paging black hole cell positioning module, configured to obtain and analyze the user network event, and determine the corresponding cell as the cell that generated the paging black hole event. The system can accurately locate the cell corresponding to the paging black hole.

Description

technical field [0001] The invention discloses a system and method for locating a cell in which a paging black hole occurs in a wireless network, and belongs to the field of wireless network optimization. Background technique [0002] The wireless paging success rate is also an important network quality indicator, which directly affects other network quality indicators such as the incoming call connection rate and short message reception success rate. Maintaining and improving the success rate of wireless paging has always been the focus of network optimization. [0003] The paging black hole refers to the network coverage area where the called user cannot normally respond to the network paging to establish a call connection (that is, the paging non-response area, hereinafter, each paging non-response is referred to as a paging black hole event). [0004] There are many reasons for paging black holes, mainly including wireless coverage, PCH (Paging Channel) channel resource...

AI Technical Summary

Problems solved by technology

[0010] 1. The road test and CQT test can only find paging black holes on the road or in key coverage areas, but the paging hole problem can be found in the whole network cell, so it can only analyze and optimize the cause of the coverage black hole problem in some cells;

[0011] 2 Road test and CQT test can be difficult to locate the cause of the paging black hole only by the downlink level, only a small part of the problem can be seen
