Soft switching fault analyzing method

Abstract

The present invention discloses soft switching fault analysis method. When soft switching failing or fault occurring, RNC output assignment type message, OMC hereby analyzing fault reason. Said outputted appointed type information includes message type, IMSI, optima cell information, active set information, soft switching fault reason, wireless accessing bearing information, monitoring set cell information, target cell information, soft switching trigger, and switching type etc; also indicating how to utilize these information to make fault analysis.

Description

technical field [0001] The invention relates to handover technology in mobile communication, in particular to soft handover technology of wideband code division multiple access system. Background technique [0002] Wideband Code Division Multiple Access (WCDMA for short) is one of the international standards for third-generation mobile communications in the world accepted by the International Telecommunications Union (ITU for short). It can also be said to be the first third-generation mobile communication system put into commercial use in the world, and it is also the frequency division duplex (Frequency Division Duplex, FDD for short) frequency band standard of the third-generation mobile communication system in Europe. Since the UMTS adopts a Wideband Code Division Multiple Access (WCDMA for short) air interface technology, the UMTS system is generally also referred to as a WCDMA communication system. [0003] As shown in Figure 6, the UMTS system adopts a structure simi...

Problems solved by technology

[0022] In actual application, the above scheme has the following problems: the cause of the failure cannot be efficiently found

Specifically, first, for the performance statistics function, performance statistics is a long-term, or a statistical function of periodic tasks, which counts the success rate or failure rate of soft handover within a period of time. It is very rough in itself, and this function is to count historical data, so it is not possible to analyze the abnormality of the soft handover failure.

If the granularity of performance statistics is increased and statistics on the causes of soft handover failures are added, it will inevitably lead to the appearance of a large amount of data, which will affect normal services.

[0023] Second, for the whole network signaling detection method, it is a kind of real-time tracking, which needs to be tracked by special third-party instruments on all interfaces. This kind of tracking will generate a lot of data. The current 2G full network signaling Order tracking only tracks the news between the networks, that is, the news of the core network, and does not track the access network

How to obtain useful information from a large number of message traces will be a very large workload

In addition, tracking through signaling requires a lot of experience, and can be very keen to find problems in messages. This method is not easy to promote among maintenance personnel.

[0024] Third, for alarms, generally speaking, the focus is on equipment failures, and less attention is paid to user failures.

For example, when the user fails to switch due to wireless reasons, it cannot be reflected in the alarm

Therefore, the alarm basically cannot reflect or solve the problem of switching
