Embodiment
In an embodiment of the present invention, MGCP uses H.248 agreement.H.248 agreement is the international standard protocol of media gateway controlling, by ITU-T and common exploitation of IETF and approval, delivers with the RFC3105 file, and wherein H.248 ITU-T is called, and IETF is called Megaco.
In an embodiment, automated test tool adopts TTCN.TTCN is international protocol test standard (standard No. for X.292), mainly finishes the functions such as structure, transmission, reception and coupling of message.In the reality, also can adopt other automated test tool, as long as can finish structure, transmission, reception and the matching feature of message.
The upper strata control program of sound card adopts RealPhone.RealPhone is a Huawei Tech Co., Ltd based on the graphical interface program on the Windows operating system of operating in of Dialogic analog voice card exploitation.RealPhone provides simple command interface, and as server, receives the order from a plurality of clients, and sound card is operated and controlled, and realizes the emulation of phone.In the reality, other control program also can adopt, as long as all functions of energy emulation phone.
The basic format of the order that RealPhone provides is: BxCx Command[Parameters].Wherein BxCx is a port-mark, and the digital x of B back represents sound card sequence number (can insert the polylith sound card on the PC), and C back numeral x represents the port sequence number on this sound card, and Command is a character string command, and Parameters is an optional parameters.For example: " B1C1 Offhook " order is to want the B1C1 port to carry out the off-hook operation, and " B1C2 Dial 87654321 " wants the B1C2 port to dial the number 87654321.
Fig. 3 (a) is the actual networking diagram of NGN; Fig. 3 (b) is the networking diagram that carries out automatic test of the present invention.Can more easily understand the basic principle of this test model by contrast.
At first with reference to Fig. 3 (a), the actual networking of NGN has four layers from top to bottom, and its action and function simply is described below:
Network control layer: SoftSwitch is responsible for control and management to equipment such as gateways as net control device, finishes work such as continuing of service call.
Core exchange layer: i.e. packet-based core networks can be IP network, ATM net or other Packet Based Network, and what adopt in the native system scheme is IP network, and its major function is the control messages (H.248) between voice-bearer Media Stream and MG and the SoftSwitch.
Edge access layer: the pairing tested object gateway of the present invention program MG is in edge access layer.MG is responsible for terminal use's access, and the up Ethernet interface (FE) that provides carries out communication by H.248 agreement and the SoftSwitch that is carried on the IP network, descendingly directly links to each other with the terminal telephone set by analog line.MG finishes terminal use's access and Media Stream is changed between Packet Based Network and PSTN net.
User terminal: here user terminal is ordinary telephone set.
Corresponding to the networking of reality,, just should simulate the ancillary equipment of MG and control with automation tools in order to realize full automation test to MG:
Replace actual SoftSwitch with TTCN.Can construct message packet according to the demand of test by TTCN, and send to MG, also receive message packet simultaneously, and mate with expected result from MG.Can control MG by the method.
Replace telephone set with sound card.Sound card provides the plain old telephone mouth, can be installed on the PCI slot of PC, by operating in the control of the control program RealPhone on the PC, can finish elemental motions such as off-hook, on-hook, dialing, hooking, can carry out detection and Identification to various signal tones such as dialing tone, ring-back tone, ring back tone, busy tones, in addition, can also carry out the confirmation of Media Stream, whether can two-way call with checking.
TTCN also is connected as setting up TCP between a client and the RealPhone except simulation SoftSwitch, according to the flow process of test, sends to RealPhone in needs and orders the corresponding operating of finishing telephone set.Such as, in needs B1C1 off-hook, TTCN can send out one " B1C1Offhook " order and give RealPhone, and RealPhone receives orders the back just to the operation of B1C1 port execution off-hook.
According to as above scheme, TTCN both can finish abundant testing protocol consistency as core control part, can combine with sound card again, realized the full automation of professional test.
The flow chart of the basic voip call that Fig. 4 is undertaken by agreement H.248 for embodiments of the invention.In this embodiment, by the basic voip call that agreement is H.248 carried out, in test process, Tel1 is as caller, and Tel2 is as called.
Among the figure, TTCN is the core of whole calling control, and MG1 and MG2 are equipment under tests, Tel1 and Tel2 be respectively with MG1 and sound card that MG2 links to each other on two ports, RealPhone operates and controls Tel1 and Tel2 by the order from TTCN.Need to prove that in addition every message all comprises order and corresponding response simultaneously among the figure, clear for flow process just, the message of the response of not drawing.Calling procedure is described in detail as follows:
In step 1, at first TTCN sends the Offhook order to RealPhone, after RealPhone receives this order, the pairing port of Tel1 is carried out the off-hook operation.
Receive the off hook signal of Tel1 at step 2, MG1 after, report off-hook event to TTCN (SoftSwitch) by Notify message.
After step 3, TTCN receive offhook message from MG1, (context is Context to send Add order establishment context to MG1, it is the notion in H.248, translations associated domain again, the correlation of representing a plurality of terminal rooms comprises that the topological relation of terminal room and medium mix and exchange parameter etc., and detailed content please refer to RFC3015), having " dt " signal simultaneously in the Add order, is that requirement MG1 is put dialing tone to Tel1.In addition, in the response to the Add order, MG1 can report to TTCN to the media information of distributing to Tel1 (as IP address, receiving port number, voice coding modes etc.), and in follow-up message, TTCN can be the called side of these information notifications.
Send the Listen order at step 4, TTCN to RealPhone, monitor the sound of Tel1 port.
Monitor the sound of Tel1 port in step 5, RealPhone, when detect be the dialing tone signal after, this result (Dial tone) is notified to TTCN.
In step 6, because Tel1 has correctly heard dialing tone, so TTCN continues to require RealPhone that Tel1 is carried out dial-up operation, and in Dial order with on the number that will dial.
After step 7, dialing were finished, MG1 can give TTCN the number of receiving by the Notify information reporting, and TTCN can check whether the number of being received is correct.
Continue to monitor that by Modify order request MG1 any incident of Tel1 is existed side by side promptly reports (" * " represents any incident) in step 8, TTCN.
At step 9, TTCN the number of receiving is analyzed, find called after, send the Add order to the gateway MG2 at called Tel2 place.The same with step 3, MG2 can also report to TTCN to the media information of distributing to Tel2 in the response message to the Add order.
After step 10, the success of Add command execution, TTCN wants MG2 to put ring back tone (ri) to Tel2 by Modify message again.
In step 11, again in called bell signal, TTCN also wants MG1 to put ring-back tone (rt) for caller Tel1 by Modify message
Send the Listen order at step 12, TTCN to RealPhone, monitor the sound of Tel2 port.
At step 13, RealPhone the ring back tone of hearing at the Tel2 port (Ring tone) is reported to TTCN.
Send the Listen order at step 14, TTCN to RealPhone, monitor the sound of Tel1 port.
At step 15, RealPhone the ring-back tone of hearing at the Tel1 port (Ringback tone) is reported to TTCN.
Receive the off hook signal of Tel2 at step 17, MG2 after, give TTCN by the Notify information reporting.
At step 18 and 19, TTCN respectively to caller and called transmission Modify message, and the media information of informing the other side respectively is (in step 3 and step 9, the gateway of calling and called has reported to TTCN to the media information of oneself in the response message to the Add order), simultaneously connection is revised as SR (transmitting-receiving) state.Like this, just can directly not carry out the Media Stream communication by TTCN between Tel1 and the Tel2, so far, conversation has been set up.
Work in step 20, this step is to carry out medium to confirm whether the conversation between checking Tel1 and the Tel2 is normal.Verification method is: Tel2 dials a string number, can correctly hear the number of being dialled at Tel1, and Tel1 dials a string number more conversely, also can correctly hear the number of being dialled at Tel2.The work that these medium confirm all is to be finished by RealPhone under the control of TTCN.
After step 21, medium confirmed to finish, TTCN sent the Onhook order to RealPhone, requires the Tel1 on-hook.
Receive the on-hook signal of Tel1 at step 22, MG1 after, report onhook event (on) to TTCN by Notify message.
Send the Subtract order at step 23, TTCN, the context that requires the MG1 deletion to be set up for the Tel1 conversation.
Send any incident (this step mainly is to prepare for call out next time) that Modify order request MG1 monitors Tel1 at step 24, TTCN.
Send the Modify order request at step 25, TTCN to MG2 and put busy tone (bt) to Tel2.
Send the Listen order at step 26, TTCN to RealPhone, monitor the sound of Tel2 port.
At step 27, RealPhone the busy tone of hearing at the Tel2 port (Busy tone) is reported to TTCN.
Send the Onhook order at step 28, TTCN to RealPhone, require the on-hook of Tel2 port.
Give TTCN by the Notify message report receive the on-hook signal of Tel2 at step 29, MG2 after.
Send the Subtract order at step 30, TTCN, the context that requires the MG2 deletion to be set up for the Tel2 conversation.
In step 31, the same with the 24th step, TTCN sends any incident that Modify order request MG2 monitors Tel2, prepares for call out next time.
So far, a complete calling procedure just is through with.Whole process is without any need for manual intervention, and full automation is realized.TTCN can carry out a plurality of test cases automatically continuously, after we have write a large amount of automatic test cases, just can allow these use-cases carry out continuously, and this moment, the tester just can do other thing, had improved testing efficiency so greatly.Because automatic test script can be reused, can be used for the MG product of different size in addition, avoid a large amount of repeated labors of tester, save human cost.
