Abstract
The invention relates to fields of testing and debugging, network optimization, fault diagnosis, etc. of a mobile communication system network. The invention aims to solve problems that a traditional resolver for mobile communication air interface protocol is heavy in weight and large in size, and the carrying and the outdoor power supply of the traditional resolver is difficult and so on. In the present invention, functions of a data acquisition part and a data analysis part in a traditional resolver for mobile communication air interface protocol are separated to form two independent devices respectively, namely, a data acquisition device and a data analysis device. The whole functions of the traditional resolver for mobile communication air interface protocol are realized by a combination of the two devices. Therefore, the weight and the size of the two independent devices of data acquisition and data analysis are greatly reduced, making the carrying convenient; the power consumption of each device is decreased, mitigating the burden of power supply.
Description
Technical field
The present invention relates to the test and the debugging of mobile communication system network; The test of the test of base stations in mobile communication system and GSM portable terminal; The interconnectivity test of GSM equipment, the network optimization of GSM, the failure diagnosis of GSM.
Background technology
The base station and the electric wave signal between the portable terminal of moving communication system transmit communication each other according to air interface protocol.Thereby aerial electric wave signal is resolved detailed channel information data and the signaling information data that obtain three layers of ground floors to the according to the standard agreement of air interface; Network operation status analysis, traffic analysis and system trouble analysis are played an important role; It is the important means of communication test and network technology parameter adjustment between base station and the portable terminal; Therefore air interface protocol is resolved instrument or system is a GSM, particularly the important testing equipment of the third generation and later GSM thereof.
Traditional mobile communication air interface protocol is resolved instrument and partly is made up of data acquisition, storage, data parsing and user interface etc.Because technology such as the loading of the aerial tcp data segment of the third generation and later GSM thereof, unloading, modulation, demodulation are high-leveled and difficult, algorithm is numerous and diverse tediously long, it is very powerful therefore to need air interface protocol to resolve the function of instrument.In order to realize high sensitivity and high-precision data acquisition, data acquisition module often adopts high accuracy and high reliability components and parts, so volume and power consumption are all big than common mobile terminal.For the high speed and the high-accuracy arithmetic of implementation algorithm, guarantee the practicality of instrument, the parsing part of instrument is often used special high-performance FPGA system or other high performance computation systems that makes.Therefore, traditional mobile communication air interface protocol is resolved relatively heaviness of instrument, and weight is usually all more than 40 kilograms, and volume is bigger.In addition, in order to guarantee system's electricity consumption of part of data acquisition, data parsing part and other parts, the power requirement of power supply is higher, generally all more than 500 watts.Yet for operator, test of reality such as the test of communication system, debugging, failure diagnosis, the network optimization and debugging operations major part are all carried out in the outfield, need often carrying testing equipment.This large test instrument is general use test vehicle when field testing, by the testing vehicle supply power.Yet weight more than 40 kilograms and bigger volume bring inconvenience to carrying; Power requirement more than 500 watts has surpassed the power supply capacity of common test vehicle, needs to increase special power supply unit.Like this, powerful but traditional mobile communication air interface protocol heavy huge and power consumption is resolved instrument and when reality is used, is had inconvenience.
Summary of the invention
Therefore, the objective of the invention is, make the convenient in carrying of field testing, power configuration easy, and can take into account field testing and indoor test in order to address the above problem.
To achieve these goals, the present invention proposes the part of data acquisition of traditional mobile communication air interface protocol parsing instrument is separated with the function of data parsing part, forms two independently instruments respectively, i.e. data acquisition unit and data parser.The function of tradition mobile communication air interface protocol parsing instrument is realized by the combination of data acquisition unit and data parser.The data format that data acquisition unit is gathered meets the requirement of the input data of data parser, and the external interface unification of data acquisition unit and data parser makes things convenient for both to interlink and data are transmitted mutually.Like this, the device formed of two instruments that couple together has replaced traditional GSM air interface protocol to resolve the allomeric function of appearance.Independently the weight of body monomer reduces greatly, volume dwindles greatly for two of data acquisition unit and data parsers, brings convenience to carrying; The power of every instrument reduces, and supplies with to power supply to have alleviated burden.
Because it mainly is labor in the purpose of field testing that the mobile communication air interface protocol is resolved instrument; The demand that data acquisition and data parsing are carried out simultaneously is lower; So can consider that in data acquisition phase vehicle-mounted instrument only uses data acquisition unit, thereby alleviate carrying burden and power supply supply burden.If data parser adopts the universal high speed computing system, just multiple different parsing software can be installed in same resolver, thereby realize a tractor serves several purposes.Therefore the present invention has improved the practicality and the convenience of instrument.Simultaneously because data parser can be shared characteristics, improved service efficiency, return the user approach that reduces cost of investment be provided.
Characteristics of the present invention are:
● traditional mobile communication air interface protocol is resolved instrument be split as independently instrument of two of data acquisition unit and data parsers, easy to use flexible.
● can replace traditional air interface protocol to resolve instrument fully by the combine performance of the testing apparatus formed of data acquisition unit and data parser.
● only need the vehicle carried data collecting device during image data of outfield, light, power consumption is little, therefore practical more, efficient.
● can use a data parser to resolve the data that many data acquisition units are gathered in the different location, resolve instrument than traditional air interface protocol and improved service efficiency, greatly reduce customer using cost.
● if resolver adopts high-performance computing system arranged side by side to realize analytical capabilities with pure software, thereby then a resolver can be installed multiple parsing software parsing different pieces of information, can realize a tractor serves several purposes more easily, becomes the integration analysis center.
● can be according to actual conditions difference upgrade data collector and data parser, the trouble when having reduced the system upgrade that brings because of system interlink.
