Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of to TETRA(Terrestrial Trunked Radio, terrestrial trunked radio) method and system tested of system air interface protocol.
Background technology
TETRA digital clustering communication system is a kind of wireless clustering mobile communication system based on digital tdma technology, this system is ETSI(European Telecommunications Standards Institute, ETSI) combine use department, manufacturer, detection department and even government department, in order to meet the open system of the specialized department of European Countries to the needs design of mobile communication, formulation unified standard.TETRA digital clustering communication system can provide command scheduling, transfer of data and telephone service on same technology platform, it not only provides the scheduling feature of multigroup group, but also short data information service, Packet data service and digitized full duplex mobile telephone service can be provided.
TETRA Digital Clustering air interface protocol has stipulated that the network equipment/mobile terminal air interface signals transmits mandatory rule, having described concrete function and the implementation procedure of each layer in the network equipment/mobile terminal protocol stack, is the basic guarantee that can intercom mutually between the network equipment of different vendor and mobile terminal.Therefore, the exploitation to digital cluster system air interface protocols, must observe corresponding Digital Clustering air interface protocol.
TETRA Digital Clustering air interface protocol has adopted the structure of layering, and the schematic diagram of its air interface protocols model as shown in Figure 1.According to signaling information and the user profile of TETRA Digital Clustering air interface transmission, by TETRA Digital Clustering air interface protocols MAC(Medium Access Control, MAC layer) on, be divided vertically into chain of command (C-face) and user's face (U-face), chain of command processing control information and Packet Service, user's face is processed voice service and circuit data service.
Each layer of 26S Proteasome Structure and Function of TETRA Digital Clustering air interface protocols is as follows:
Physical layer
Mainly realize the conversion of radio frequency sending and receiving, modulation and demodulation, sending and receiving, regularly, the functions such as power control of time division multiple access access and mobile terminal.
Data link layer
Data link layer can be divided into two sublayers: MAC(Medium Access Control, MAC layer) and LLC(Logical Link Control, logical link control layer).MAC layer mainly carries out deal with data, to be applicable to transmission of radio links.The management of the transmission of LLC layered data processing, forwarding, segmentation, restructuring and logical links and control etc.
Network layer
Network layer can be divided into two sublayers: MLE(Mobile Link Control Entity, mobile link controlled entity) and SNAF(Sub-Network Access Function, subnet access function) entity.MLE is responsible for controlling the function that lower level is relevant to radio, comprises management, the mobile management in registration area, mobile terminal Identity Management and the service quality control etc. of wireless link.
Along with TERTA digital cluster system railway at home and abroad, subway, light rail, airport, harbour water conservancy, public security, safety, the application of the specialized departments such as army, the product of TETRA Digital Clustering production firm constantly increases both at home and abroad, at present, TETRA Digital Clustering production firm and TETRA industry alliance (TETRA MoU) still carry out the HIST of TETRA Digital Clustering protocol stack by manual mode or semi-automatic mode both at home and abroad, inefficiency, can not carry out real-time testing, testing time is long, after test, needing to expend a large amount of manpowers and time carries out interpretation of result to the journal file of Devices to test collection, often after the several months, could obtain final testing result.Therefore, in the urgent need to setting up a set of Digital Clustering of TETRA fast air interface protocols automatic mutual operability test macro.
A kind of method that TETRA air interface protocol is carried out to uniformity test of the prior art mainly comprises: the method indentification protocol realizes the consistency with TETRA air interface protocol standard, it is a kind of functional test, in fact to utilize one group of cycle tests, at certain net environment, to IUT(Implemen-tation Under Test, tested agreement realization) carry out Black-box Testing, by the relatively actual output and the similarities and differences of expecting output of IUT, judge that IUT is to what extent consistent with protocol description, establish by the height of IUT success rate when system interconnect of uniformity test.
In the method, test macro (TEST SYSTEM) is exactly the TETRA system of required test, SUT(System Under Test, system under test (SUT)) be to have inherited TTCN(Testing and Test Control Notation, test and test control representation method) the tool software of test model, mobile terminal protocol in this tool software simulation reality is realized situation and is write test case, and utilize TCP(Transmission Control Protocol, transmission control protocol) by netting twine, SUT is connected with test macro, by netting twine, between SUT and test macro, carry out transfer of data.
Above-mentioned shortcoming of TETRA air interface protocol being carried out to the method for uniformity test of the prior art is: the method simulating mobile terminal carries out the test of TETRA air interface protocols, rather than test with true mobile terminal, this just can not test the protocol test under the mobile terminal of variant manufacturer, the TETRA air interface protocol test of carrying out is like this true and perfect not, has artificially changed the real reaction situation of many mobile terminals.
The SUT providing must use netting twine to be directly connected and just can to test with TETRA system by Transmission Control Protocol, if while running into the situation that cannot directly be connected with TETRA system with netting twine, just can not test.And with regard to having masked in many wireless transmission processes, in air dielectric, transmit caused problem like this.
Tester in test process according to the requirement of test case, by pseudo-terminal equipment, to the network equipment, send control signaling, the network equipment is to pseudo-terminal equipment feedback signaling, each signaling has many parameters, and due to each test case require different, signaling parameter also can be different, the correct template of neither one is compared, and only by tester, compare, obtain the test result time longer, can not test in real time, the test result finally obtaining is accurate not enough.
