Background technology
In the honeycomb field of mobile communication, general base station system all is to constitute by hanging some transceiver BTS under the concentrated base station controller BSC, wherein base station controller BSC is the centralized control module in the base station system, all users' calling all will be reported to BSC to handle from the transceiver BTS of sub-district of living in, so BSC is to embody an important indicator of base station system performance for the disposal ability of traffic; In order to verify that whether BSC can reach desired traffic handing capacity, need carry out the test of Bulk Call.
When carrying out the Bulk Call test, need to realize numerous user's voice call business.Whole base station equipment comprises BSC and some BTS, wherein BSC is made of center frame and some vocoder frames, the center frame includes central controlled network control unit NCM, call processing module CPM and network interface unit NIM etc., and wherein network control unit NCM and call processing module CPM are the key modules in the equipment; The vocoder frame then includes numerous voice coder SVBS as BSC side resource block, and vocoder unit SVE required in the speech business is provided, and a voice coder contains 120 tunnel vocoder unit altogether, corresponding 120 voice calling service; Transceiver BTS is used to realize the modulating/demodulating and the radio frequency of baseband signal, and by air wireless interface and mobile communications, communicates by letter with BSC by Abis interface, provides speech business needed Channel Elements CE in BTS.In such equipment, it obviously is worthless adopting true environment to test traffic fully, method in common is that BTS is carried out emulation, Message Processing by the analogue mobile station of the Abis interface between BSC and the BTS-transceiver pusher side, thereby the formation call flow reaches the purpose that the traffic of true BSC is tested.Simulate the operation flow of BTS side such as the test case of utilizing the TTCN language description, realize simulation registration, calling, the handoff procedure of mobile phone, when test, adopt the form of multipath concurrence, form the specific call amount, on real BSC, form the traffic environment, and then the index of correlation of test b SC side.
There is a bigger deficiency in the analogue system of this in actual use simulation BTS, is in particular in that the telephone traffic of institute's emulation is less, and is big to the demand of analog machine.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Bulk Call emulation test system of base station controller, to overcome shortcoming excessive to the analog machine demand in the prior art.
Bulk Call emulation test system of the present invention is used for the center frame of testing base station controller, comprises test background, test job foreground 1 and test job foreground 2; Described test background is a PC physically, links to each other with test job foreground 1 by Ethernet interface, is used to provide man-machine interface, carries out overall arrangement and control; Described test job foreground 1 is identical on hardware configuration with test job foreground 2, comprises machine frame and inner veneer, and each machine frame all has the RS422 port, joins with corresponding RS422 port on the center frame of system under test (SUT) base station controller; Described test job foreground 1 is used for emulation travelling carriage-transceiver pusher side, described test job foreground 2 is used for the voice coder side of simulation base station controller, both structurally form one-to-one relationship, a machine frame on described test job foreground 1 constitutes a foreground basic module with a corresponding machine frame on described test job foreground 2, but the flow process that 360 speech channels of emulation are called out, switched; Described test job foreground 1 and test job foreground 2 are formed by the basic module The parallel combined, and the address port that is connected according to the true module of institute's emulation of each basic module and system under test (SUT) connects.
Adopt test macro of the present invention, compared with prior art, owing to made full use of software and hardware resources, keep a firm hand on the crucial process points of call test, by simulating BTS substantially with symmetrical structure structure foreground emulation module, SVBS, realized the expansion of call simulation with 3: 1 ratios, not only make telephone traffic reach designing requirement, more saved needed analog machine, greatly reduce the cost of environment construction, realize calling curve data structure in test background simultaneously, be used to refer to the control that the respective call amount is carried out on the foreground, improved the opening of traffic model test.
