Background technology
In mobile communications, except carrying out the construction of communication network, mobile operator also needs to carry out the network optimization, to safeguard the normal operation of mobile communications network, to ensure the telecommunication service quality of mobile communications network.
After the network optimization refers to that communication network builds up, carry out various optimization (comprising software, hardware, configuration etc.) on this basis.In the network optimization, need the performance for mobile communications network to carry out testing evaluation, common testing evaluation mode has drive test (driving test, DT), walking test (walking test, WT).During drive test, drive test instrument is placed on motor vehicles, in the performance of traveling limit, road top test network; During walking test, tester carries portable network test terminal, in the performance of the place such as building, tunnel walking one side test network.
Mobile operator wish break down or customer complaint time, can fault point promptly and accurately, keep in repair fast.At present, in order to looking up the fault point, need manually to investigate, for room divided antenna, need to carry out antenna detection one by one in the building of room subsystem installation.For antenna for base station, also to climb up on the steel tower at its place, roof or mountain top and detect one by one.Current method has a lot of shortcoming:
(1) check antenna one by one, need the artificial of at substantial, efficiency is very low, and cost is very high;
(2) situation of antenna performance decline or damage cannot be learned in time, ageing very poor;
(3) after there is COMMUNICATION NETWORK PERFORMANCES fault or customer complaint, cannot determine particular problem point, difficulty and the cost of investigation are high.
In order to solve the problem, for mobile communications network, existing scheme places a mobile communication terminal (as mobile phone) near antenna, by this mobile communication terminal (i.e. active detection terminal, active probe) communicate with mobile communications network, if there is communication failure, then think that certain neighbouring antenna or communication line corresponding to antenna, equipment have fault.Although this method has certain effect, but still there is obvious shortcoming:
(1) active detection terminal price is high, can not place fixing mobile communication terminal on each antenna side;
(2) active detection terminal needs to regularly replace battery, and also need to make regular check on, maintenance cost is higher;
(3) in the mobile communication system of reality, active detection terminal installation site distance antenna has certain distance, is subject to the impact of environment, multipath signal, its jitter received, signal excursion is large, accurately can not judge the decline of antenna performance.Meanwhile, active communication terminal can with multiple cell communication, switching cell, even if detect that communication has fault, concrete fault antenna can not be determined.
