Embodiment
Basic thought of the present invention is: radio network controller sends the measurement request that NMS measures type that carries to the base station; Base station in response request of measuring and return measurement response trigger the measurement control that upward signal that the analog transmissions terminal to NMS sent is measured.
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
Below prior art and the present invention are compared elaboration, to embody the advantage of the present invention better with respect to prior art.
The measurement control of prior art mainly is directly to be fixed against the down-run survey value, and descending existence interference can cause the insecure defective of this down-run survey value, new measurement demand is: avoid this insecure defective, avoiding with this class measured value serves as that foundation is carried out network analysis and the network optimization causes the low problem of accuracy.And in the existing mobile communications system, particularly TD-SCDMA mobile communication system, do not have a kind of measurement controlling mechanism at present, can support above-mentioned measurement demand fully.
In the mobile communication system of time division duplex, because the up-downgoing channel has reciprocity in the network, can consider to adopt specific upward signal is carried out Measurement and analysis, calculate information such as downstream signal intensity and report analysis, make system reach the effect of the descending covering of test.Because up emission can state no interference signal, make test signal evade the influence of disturbing, thereby make the data that obtain objective reality more.That is to say, if consider at upward signal measure and with obtain around here the down-run survey value, insecure defective when the down-run survey value of Huo Deing has just avoided prior art to have interference so can improve the accuracy of the network analysis and the network optimization.Thereby take this measurement controlling mechanism of measuring at upward signal, can support above-mentioned measurement demand fully.Yet, do not have the implementation of measuring control at upward signal at present as yet.
The present invention just is being based on above-mentioned consideration, has realized measuring at upward signal the scheme of control.The present invention measures control at network side at upward signal, and then reports measured value at this upward signal to offer the data foundation of radio network controller as the network analysis and the network optimization.That is to say, the base station is measured required measured value with upward signal and is reported according to the indication of radio network controller, so that radio network controller is further analyzed, comprehensively these measured values, finally calculate the actual coverage condition of existing network, thereby guaranteed the accuracy of the network optimization.
