Description
Technical field
The present invention relates to communication technical field, be meant especially a kind of simulation base station transceiver (BaseTransceiver Station, BTS) and the method and system of user terminal.
Background technology
At present, quality and performance for the test communications network equipment have a variety of emulation technologies.Particularly the emulation technology of carrying out large speech affairs test by simulating BTS and user terminal has become the detection means that how tame communication apparatus supplier must use in beginning and later edition upgrading.The free-revving engine of large speech affairs test is exactly to reach the performance parameter of hardware as much as possible in the system being tested and testing out as far as possible exactly system.The network configuration of base station system as shown in Figure 1 in the prior art, comprise a base station controller (BaseStation Controller, BSC), several BTS and a large amount of user terminals, wherein, BSC mainly is responsible for functions such as wireless network management, RRM and call treatment; BTS is used to realize wireless transmission and relevant controlled function; User terminal is used to the user that various services in the communication network are provided, as speech business, data service etc.
When BSC is tested, because lab resources is limited, often adopt some emulation technologies to come simulating BTS and user terminal, finish test to function and the performance of BSC.Present emulation mode mainly contains two kinds: the equipment component on a kind of BTS of being to use comes the partial function of emulation user terminal and true BTS, finishes the butt joint with BSC; Another kind is to use the equipment component on the BSC to come the function of emulation user terminal and BTS.The former shortcoming is that equipment infusion of financial resources is big, but the capacity of emulation is little, and BTS hardware can only the some mobile phones of emulation and the function of a BTS.The latter's advantage is that the emulation capacity is big, and a BSC can a plurality of BTS of emulation and several users.
Use equipment component on the BSC come emulation user terminal and BTS function system network architecture diagram as shown in Figure 2, this system is made up of control appliance 22 and BSC network element 21, wherein, BSC network element 21 comprises analogue system and tested BSC, wherein, analogue system comprises emulation signaling processing module 211 and artificial service processing module 212, is respectively applied for emulation and the professional processing of finishing signaling between emulation user terminal and the simulating BTS; Tested BSC comprises tested signaling processing module 214 and tested Service Processing Module 215, is respectively applied for to finish signaling among the tested BSC and professional processing, and interface module 213, is used to realize the communication between analogue system and the tested BSC.Control appliance 22 links to each other with emulation signaling processing module 211, is used to finish the traffic modules configured, starts and stops.Wherein, emulation signaling processing module 211 is used for the function of simulating BTS and user terminal, promptly according to real voice call flow process, inverted configuration real handset or BTS want the message of emulation to send to the BSC side, forward direction is when receiving the message that the BSC side is come, handle according to signaling process, and construct next bar reverse message and send to BSC.Such as: article one message is the call message of mobile phone in the true phone flow process, this message is issued the BSC side after the BTS encapsulation, emulation signaling processing module 211 is just constructed this call message so, comprised in the message and wailed sign indicating number, called number, place cell information etc., and the imitation BTS encapsulation process call message is encapsulated, send to the BSC side.For BSC, receive this call message, it can only detect the legitimacy of this message, but it can not detect this message fully be that real handset is sent out or the emulation mobile phone is sent out.Handle after true BSC receives call message, send a wireless links and set up message to BTS.After emulation signaling processing module 211 is received this message, according to the information of carrying in the message, learn that this message sends to BTS, then imitate true BTS this message is handled, as Resources allocation etc., and construct next bar connection message according to the signaling simulation flow and oppositely send to BSC.That is to say, emulation signaling processing module 211 as required, can simulating BTS, also can the emulation user terminal, deciding current according to the requirement of signaling process is simulating BTS or emulation user terminal, after emulation signaling processing module 211 receives message, can judge this message according to the information in the message and issue BTS's or issue user terminal, carry out corresponding operation according to judged result imitation BTS or user terminal.
But the mode of using the equipment component on the BSC to come emulation user terminal and BTS to be adopted in the prior art is positioned at same network element as system and tested BSC, and promptly analogue system is to be realized by the part hardware device among the tested BSC, therefore has following shortcoming:
One, because the employed interface of emulation module is the interface of BSC network element internal, therefore can only connect a tested BSC, so can't carry out emulation testing to the direct-cut operation between a plurality of BSC.
Two, analogue system and tested BSC belong to same BSC network element, because analogue system has taken the resource of tested BSC network element, therefore, the heap(ed) capacity of tested BSC network element can't accurately test out.
Three, because interface module is that analogue system and tested BSC are shared, therefore, can't the docking port module do accurate test, just can't accurately test every block of plate on the tested BSC network element.
Four, because a shared interface is coupled greatly between analogue system and the tested BSC, and analogue system need be followed the upgrading of system under test (SUT) and upgrade, the release maintenance amount is big.
