Above three kinds of implementations of testing equipment of the present invention cut both ways, below the access exploration formed with the third implementation switch and insert the test macro that switches and be elaborated, as shown in Figure 3.
Test macro of the present invention comprises travelling carriage, base station and control desk, wherein:
Control desk is arranged on outside the base station, comprises a control module, and this control module provides a configuration interface for the tester, disposes relevant parameter according to the test needs, and configuration information is sent to the filtration treatment module of moving in the base station.Whether the relevant parameter that is used to dispose has: need repeater system to insert message (comprising call message and page-response message), whether need access acknowledgement message and the channel assignment message tackled and the time of closing forward channel.
The control module of control desk can connect with a plurality of base stations, controls a plurality of filtration treatment modules simultaneously.
The base station comprises channel processing module, filtration treatment module and common signaling processing module.Wherein:
Channel processing module mainly is responsible for the physical layer process and the control of air traffic channel, opening, closing as corresponding physical channel, on the channel of correspondence, send and reception message, finish the conversion of all message and air interface signals, handle all message that travelling carriage sends or receives;
The common signaling processing module mainly is responsible for the high-level signaling of each travelling carriage in the scope of whole base station and is handled, and as the confirmation to inserting, transmitting channel assignment message etc. are finished the mutual signaling with travelling carriage;
The filtration treatment module is arranged between channel processing module and the common signaling processing module, to filter message between the two, and whether transmit or tackle these message according to the configuration of control module decision, and and have control interface between the channel processing module, close and open forward channel with the control channel processing module.
The message of filtration treatment resume module comprises that channel processing module sends to system's access message (comprising call message and page-response message) of common signaling processing module, and the common signaling processing module sends to the access acknowledgement message and the channel assignment message of channel processing module.
Wherein channel processing module and common signaling processing module are the existing modules of communication system, and filtration treatment module and control module are to switch initiate module in order to realize that access exploration switches and inserts.
In case according to setting, this filtration treatment module need be tackled the system docking that the common signaling processing module sends to channel processing module and be gone into the confirmation of message or/and channel assignment message, just need close forward channel, could trigger travelling carriage like this and switch to other base station.For the continuity that guarantees to test, and analogue mobile station gets back to the situation that original base station is inserted again, and the closing of forward channel is not forever to close, but after closing the regular hour, the filtration treatment module is opened the forward channel of having closed again.
The present invention carries out the method for testing that access exploration switches and insert switch test, mainly may further comprise the steps:
Step 1: increase control module and filtration treatment module in tested communication system;
Wherein:
Control module is used to be provided with the simulation test parameter of switching, the trigger condition that simulation is switched, and send to the filtration treatment module, need the relevant parameter of configuration to have: whether to need access acknowledgement message and the channel assignment message tackled and the time of closing forward channel;
The filtration treatment module is used to carry out the order that is provided with of control module, and the message between forwarding or interception travelling carriage and the base station system is also controlled opening of forward channel and closed.
Step 2: adjust each base station signal that participates in test, make each signal of base station intensity suitable substantially;
Step 3: the parameter that each control is switched is set on control desk, and sends to the filtration treatment module;
Step 3 is most criticals in the whole test process, according to the test needs, can simulate various access explorations switchings and insert and switch by the cooperation of each configuration parameter.
If need to select repeater system to insert message (comprising call message and page-response message), then mainly be the poor signal of simulation from the base station to the travelling carriage, and be good situation from the travelling carriage to the signal of base station.Repeater system inserts message (comprising call message and page-response message) if select not, and then the expression simulation is bad situation from the travelling carriage to the signal of base station.
Filter the switch that inserts acknowledgement message if open, mean that then travelling carriage does not receive the confirmation that inserts message, and close the operation of forward signal subsequently, cause travelling carriage to lose this signal of base station, and be forced to switch on other the base station, again initiation system inserts, and switches thereby trigger access exploration.
If open the switch that filters channel assignment message, mean that then travelling carriage does not receive channel assignment message, and close the operation of forward signal subsequently, cause travelling carriage to lose this signal of base station, and be forced to switch on other the base station, wait for channel assignment message, this has just initiated to insert and has switched.Close time of forward channel by rational selection, can simulate from the base station 1 and switch to base station 2, switch back the situation of base station 1 again.
Step 4: the initiation system inserts, comprised exhaling and being exhaled two kinds, in access procedure, filtration treatment module execution control module order is set, tested system is carried out switch test.
Particularly,, before test, by control desk parameter is set earlier, parameter is sent to the filtration treatment module of base station 1 and 2 inside, base station as testing at system shown in Figure 3.Suppose at first initiation system access on base station 1 of travelling carriage, the filtration treatment module of base station 1 has been found the message that needs are tackled according to configuration parameter, just closes forward channel by control messages control channel processing module.Travelling carriage will detect forward signal and loses like this, if travelling carriage detects the signal of another one base station 2, travelling carriage can switch to base station 2, continues to finish access procedure.
According to the type of message difference that interception is set, just can control and the access exploration switching take place or insert to switch.After once closing the forward channel certain hour, the filtration treatment module will be opened forward signal.If the time that is provided with is a little long, can proceed to test next time.If the time that is provided with is a little short, travelling carriage may switch go back to base station 1.
In test, reasonably make up each parameter, also access exploration may be switched and inserts switching combining in access procedure.
Fig. 4 is the main handling process of filtration treatment module in the method for testing of the present invention.
The filtration treatment module inserts message, inserts acknowledgement message and channel assignment message and just decide next step operation according to the configuration parameter of control module in case receive the relevant system of test travelling carriage after receiving the configuration parameter that control module sends over.
The system of receiving inserts message, and just whether the configuration decision according to control module is transmitted to the common signaling processing module, if do not need to transmit, just directly abandons, otherwise just is transmitted to the common signaling processing module;
After receiving the access acknowledgement message, whether transmit according to the configuration decision of control module equally, transmit if desired, just directly be transmitted to channel processing module, otherwise directly abandon this message, the notification channel processing module is closed forward channel simultaneously, and timer is set, after timer expiry, transmission is notified to channel processing module and opens forward channel;
After receiving channel assignment message, whether transmit according to the configuration decision of control module equally, transmit if desired, just directly be transmitted to channel processing module, otherwise abandon this message, the notification channel processing module is closed forward channel simultaneously, and timer is set, behind timer expiry, transmission is notified to channel processing module and opens forward channel.
Because not relating to a lot of systems, this scheme do not realize, therefore can apply in the different systems to have certain versatility.
Compared to prior art, access exploration of the present invention switches and inserts the testing equipment of switching, system and method is by increasing the interception function of message, and opening closing function with the forward channel of communication system base station combines, thereby realize adopting true travelling carriage simulation access acknowledgement message and channel assignment message because poor signal, transmission is less than the situation of travelling carriage, trigger travelling carriage and carry out the access exploration switching or/and insert switching, thereby accurately control inserting the switching of switching and access exploration, whether whether checking system is reasonable to the various processing that access exploration switches and access is switched, can cause the stability of system to descend.
Testing equipment of the present invention, system and method are except filtering inserting acknowledgement message and channel assignment message, also increased the filtration that system is inserted message, can simulate the various actual switch instances that may lose message like this, further improve the survey that access exploration switches and access is switched is established.
