Embodiment
Basic thought of the present invention is: radio network controller sends to base station and carries the measurement request that NMS measures type; Base station in response measures request and return measurement response, triggers the Survey control that the upward signal that sends the analog transmissions terminal of NMS is measured.
Be described in further detail below in conjunction with the enforcement of accompanying drawing to technical scheme.
Below prior art and the present invention are carried out contrast to set forth, to embody the advantage of the present invention relative to prior art better.
The Survey control of prior art is mainly directly fixed against down-run survey value, and descending existence interference can cause the insecure defect of this down-run survey value, new measurement demand is: avoid this insecure defect, avoids with this kind of measured value as according to the problem of carrying out network analysis and the network optimization and causing accuracy low.And in existing mobile communication system, particularly TD-SCDMA mobile communication system, there is not a kind of Survey control mechanism at present, above-mentioned measurement demand can be supported completely.
In the mobile communication system of time division duplex, because in network, up-downgoing channel has reciprocity, can consider to adopt and Measurement and analysis is carried out to specific upward signal, calculate the information such as downstream signal intensity and report analysis, making system reach the effect of testing descending covering.Because up transmitting can state no interference signal, the impact of test signal is evaded interference, thus make the data objective reality more that obtains.That is, if consider to carry out measuring for upward signal and to obtain to obtain down-run survey value around here, the down-run survey value so obtained just avoids insecure defect when prior art exists interference, can improve the accuracy of network analysis and the network optimization.Thus take this Survey control mechanism of carrying out measuring for upward signal, above-mentioned measurement demand can be supported completely.But, not yet there is the implementation carrying out Survey control for upward signal at present.
The present invention, just based on above-mentioned consideration, achieves the scheme of carrying out Survey control for upward signal.The present invention carries out Survey control at network side for upward signal, and then reports measured value for this upward signal to be supplied to the data foundation of radio network controller as network analysis and the network optimization.That is, base station according to the instruction of radio network controller, by upward signal measure needed for measured value report so as radio network controller further to be analyzed these measured values, comprehensively, finally calculate the actual coverage condition of existing network, thus ensure that the accuracy of the network optimization.
Below the scheme how the present invention realizes carrying out for upward signal Survey control is specifically addressed.
A Survey control method in NMS, the method mainly comprises following content:
Radio network controller sends to base station and carries the measurement request that NMS measures type; Measure request described in base station in response and return measurement response, trigger the Survey control that the upward signal that sends the analog transmissions terminal of NMS is measured.
Here it is to be noted: the upward signal that the analog transmissions terminal of NMS is sending by the present invention is measured as specific upward signal, measured value is obtained according to described upward signal, be in order in case follow-up using the measured value that obtains as the authentic data support of network analysis and the network optimization, improve the accuracy of network analysis and the network optimization.But the existing implementation carrying out Survey control for upward signal is not enough to the Survey control needs supporting NMS scene.That is, due to existing measured value reporting types or content, be not enough to support reporting of the described measured value obtained according to described upward signal needed for NMS system, this particular measurement value, therefore, in order to realize reporting of this particular measurement value, the present invention is by increasing a kind of new measurement type for this NMS in NMS, that is: NMS measurement type is distinguished.Carried out specification to special measurement type at the 9.2.1.23 chapters and sections of existing 3GPP TS25.433 agreement, the present invention has increased this NMS for NMS just on this basis newly and has measured type.
Here, radio network controller sends NMS special measurement request during to base station, in the message body structure of this NMS special measurement request, need to carry this newly-increased NMS measure type, it is measurement for this specific upward signal that such base station could be distinguished current thus.Afterwards, base station responds this NMS special measurement request, and returns the response of NMS special measurement, thus triggers the mechanism of carrying out Survey control for upward signal.
Here, after this mechanism triggers, subsequent base stations can report NMS special measurement to be reported to radio network controller, carries the measured value measuring type for this NMS in the report of this NMS special measurement.The NMS increased newly for NMS due to the present invention measures type, therefore, when reporting the measured value for this NMS measurement type, corresponding measured value structure need be increased in the message body structure of this NMS special measurement report, so that radio network controller, by the analysis to these measured values, reaches the demand such as network test and optimization.
Visible in sum: the triggering of this Survey control and reporting after triggering Survey control can combine by a preferred example of the present invention, be: in NMS, a kind of specifically for the NMS measurement type of this NMS by increasing, and measure in type at this NMS, the measured value analyzed required for this NMS is reported with the form of measurement report, thus provides reliable data foundation for the network analysis of this NMS and optimization.
The NMS for NMS increased for the present invention measures type, as shown in table 1 below the definition of this measurement type, and table 1 is in special measurement information, add the signal table that NMS measures type.
