Description
Technical field
The present invention relates to network optimisation techniques field, a kind of method particularly relating to wireless drive test data and signaling monitoring system data association。
Background technology
Fast development along with mobile communication technology and industry, original appraisement system " network KPI " increasingly can not reflect the impression of terminal use and the quality condition of network, therefore, a set of comprehensive, user's perception evaluation system of system and the prioritization scheme of lifting user's perception become the core of the network optimization。
End-to-end optimization is considered as solve legacy network optimization network only to carry out the defect of local optimum, promotes the inexorable trend of user's perception, end-to-end user's perception evaluation system is the basis of whole end-to-end optimization, can be divided into end to end performance optimization and the powerful support two parts to operator's lean operation。Realize end-to-end optimization, it is necessary to realize the association signaling process related analysis technology of multiplex roles。
In end-to-end analysis, it is substantially by distinct device in mobile communications network or transmission between interface, and the signaling message belonging to same communication event associates。Realize end-to-end association, it is possible to reach following effect:
1. end to end network analysis: signaling monitoring system associates with the synchronization of driver test system, it is provided that end to end signaling process, signaling delay, call-loss analysis, and can be accurately positioned calling damage produce equipment and reason, in order to improve maintenance optimization work efficiency；
2. combining wireless resource information: wave point can provide more abundant RR information, the network parameter that Abis+A mouth cannot relate to can be analyzed, each network exception event (call drop, access failure, handoff failure etc.) can be carried out the association analysis of wireless network and Access Network, analyze network failure more accurately；
3. in conjunction with precise location information: drive test data provides GPS more accurately to position information, deep layer can carry out geoanalysis exactly, could position when sending MR under signaling monitoring system Abis/Iub interface data dedicated mode, the network events such as location updating failure, access failure be cannot be carried out being accurately positioned analysis, but by the conjoint analysis with drive test file, abnormal network flow process can be decomposed, find the node that flow process is interrupted, analyze the reason interrupted, and be accurately positioned the position that Network Abnormal occurs by drive test GPS information。
