Description

Be used to realize the method and apparatus of SIGTRAN configurations match detection

Technical field

The present invention relates to the communications field, more specifically, relate to the method and apparatus that a kind of SIGTRAN of realization configurations match detects.

Background technology

In order to satisfy (Internet Protocol at IP, Internet protocol) demand of transmission over networks signaling protocol, internet engineering task group (Internet Engineering Task Force, be abbreviated as IETF) special signaling transmission group of establishment, signaling transmission (Signaling Transport is abbreviated as SIGTRAN) protocol stack support that they formulated is by IP network transmission circuit exchange of signaling.Interlayer standard primitives interface in the definition of SIGTRAN stack support circuit-switched signaling protocol hierarchical mode, thereby guarantee existing circuit switching signaling can unmodified ground use, the IP host-host protocol that also utilizes simultaneously standard satisfies the special transmission requirement of circuit switching signaling as the transmission bottom by the function that increases self.

The protocol stack that SIGTRAN is made up of one group of agreement, wherein comprised M2UA (SS7 MTP2 User Adaptation Layer, NO.7 signaling message transmission part (MTP) second level user adaptation layer), M3UA (SS7 MTP3 User Adaptation Layer, NO.7 signaling message transmission part (MTP) third level user adaptation layer), SUA (SignallingConnection Control Part User Adaptation Layer, SCCP User Adaptation Layer), (ISDN is Adaptation Layer Q.921-User for IUA, ISDN Q921 user adaptation layer), V5UA (V5.2-User Adaptation Layer, V5.2-User Adaptation Layer) is used for realizing Signaling System Number 7 respectively, ISDN (Integrated Services Digital Network, integrated services digital network) signaling, V5 Access Network signaling message is on the IP network and the signalling interworking on the original circuit network.

Fig. 1 shows the application model of the M2UA standard code of correlation technique.

With M2UA is example, the application model of M2UA standard code as shown in Figure 1:

If 0,1,2,3 four MTP link of link is arranged on the SG, and (MTP is the abbreviation of " Message Transfer Part " agreement, it is one group of agreement of ITU definition, be divided into three layers, MTP1 is a physical layer, MTP 2 is link layers, be responsible for the message reliable transmission, MTP 3 is network layers, is responsible for signaling network state-maintenance and message routing management) its interface identifier is respectively 0,1,2,3; Respectively by MGC1 (Media Gateway Controller, Media Gateway Controller) goes up management SG (Signaling Gateway, SGW) MTP link 0 on (MTPlink 0) and link 1 (MTP link 1), MTP link 2 (MTP link 2) and 3 (MTP link 3) on the MGC 2 management SG.MTP link 0 on the SG and MTP link 1 belong to AS (Application Server, application server) 0, and this AS has ASP1 and ASP 2 to provide service for it.

Yet, a problem is, all entered business state if work as ASP 0 and ASP 1, when MTP link 0 and MTP link 1 have all been set up link and have been carried out data communication, when if the user is configured to ASP 2 also for AS 0 service when configuration ASP 2 because of carelessness, because standard does not define configuration inspection mechanism, ASP 2 also can enter business state.If handle for ASP 2 from the distribution of services on MTP 0 and MTP 1 link this moment, it can not handle this two service messages that link is sent ASP 2 meeting discoveries, may send message and require to remove these two MTP links, perhaps send out an ERROR message (reason is non-existent interface identifier) to SG at least to SG; SG receives that this message thinks that later on MGC can not handle the business on these two links, also can remove MTP link 0 and MTP link 1, thereby causes two link traffic to interrupt.Because the MTP link all may have a large amount of users, if a large amount of MTP link down brings tremendous loss will for service provider and user.

Fig. 2 shows the basic service flow process in M2UA, IUA, SUA, M3UA and the V5UA agreement.

As shown in Figure 2, in M2UA, IUA, SUA, M3UA and V5UA agreement, the basic service flow process divided for four steps finished:

Step S202 after having set up the SCTP connection between two side apparatus, initiates ASP UP message to opposite end SG side by ASP (Application Server Process, application server process) side;

Step S204, the SG side receives that ASP UP message responds ASP UP ACK message later on and give the ASP side;

Step S206, the ASP side is received after the ASP UP ACK message, just can send ASP ACTIVE message to the SG side; And

Step S208, the SG side receives after the ASP ACTIVE message that response ASPACTIVE ACK message is given the ASP side.

The ASP ACTIVE message that the user sends can have the interface identifier parameter, and (it is optional that interface identifier belongs to, generally be not with), the SG side receives that ASP ACTIVE message is later on according to looking at whether the interface identifier link corresponding is configured on the interface identifier contrast SG, if the neither one interface obtains configuration on SG, just can not respond ASP ACTIVE ACK message or send ERROR message.

Yet, the problem of such scheme is, in the above-mentioned process, because the MTP link is configured on SG and two equipment of MGC respectively, so may exist configuration asynchronous, also do not dispose a MTP2 link on the MGC when might the ASP side sending ASP ACTIVE message, just can not comprise InterfaceId (interface identifier) in the ASP ACTIVE message that sends, not with the interface identifier of configuration, this in this case mechanism just can't be played effectiveness in the ASP ACTIVE message that therefore general MGC sends.

In addition on the one hand, also there is a problem in such scheme, MGC often controls the MTP link on a plurality of SG, interface identifier on the SG generally all is since 0 traditionally, the possible interface identifier with the last link that disposes of SG just of the interface identifier that has in the ASP ACTIVE message that unmatched like this ASP side is sent is identical, because the equipment two ends dispose nonsynchronous reason, can not be strict with coupling fully, as long as there is an interface identifier identical, the SG side just should be responded ASP ACTIVE ACK message, also checks not come out under the situation of configuration error like this.

In a word, for example in M2UA, IUA, SUA, M3UA and the V5UA agreement, when the two ends configuration does not match, may bring heavy losses to the user in above-mentioned correlation technique because the little configuration error of user just cause a large amount of link traffic to interrupt.

Therefore, people need a kind of method and apparatus of realizing that the SIGTRAN configurations match detects, can solve the problem in the above-mentioned correlation technique.

With reference to Fig. 5, be example below, describe in detail according to a particular embodiment of the invention with M2UA.

Fig. 5 shows according to a M2UA specific embodiment of the present invention.

As shown in Figure 5, supposing has two or more ASP to be this AS service (is that certain M2UA link collection has two or more M2UA link to provide service for it for what adopt link set-link model) in the ASP side, if ASP1 is the ASP for first transmission ASP UP message of this AS service, ASP2 is that (for what adopt link set-link model is that M2UA link 1 sends ASP UP message earlier for the ASP of the back transmission ASPUP message of this AS service, M2UA link 2 backs send ASP UP message), following treatment step is arranged in this embodiment:

Step S502: ASP 1 sends ASP UP message and gives the SG side on ASP, wherein increase local terminal configuration information (, can use M2UA link collection number etc.) in the INFO String parameter in the ASP UP message (also can be newly-increased parameter) for what adopt link set-link model such as MGC device identification, AS sign;

Step S504: after receiving ASP UP message on the SG, can find the ASP (can be to find corresponding M2UA link for what adopt link set-link model) of the correspondence that on SG, disposes, and then the AS (can be to find corresponding M2UA link collection for what adopt link set-link model) that finds this ASP to serve, and current SG goes up the configuration detection information of also not preserving the opposite end among the corresponding A S (because serving for this AS that first receives the ASP of ASP UP message among the ASP in the SG side), if comprise configuration detection information in the discovery message, the SG side preserves the configuration detection information in the ASP UP ACK message get off, and responds ASP UP ACK message for then the ASP side.As optional, (certain IP address of going up configuration such as SG adds the AS sign can to increase the last local terminal configuration information of SG in the INFO String parameter (also can increase parameter newly) in the ASP UPACK message, add M2UA link collection number for certain the IP address that can use SG to go up configuration of adopting link set-link model, perhaps any information that other can this AS of unique identification);

Step S506: ASP 1 has received the ASP UP ACK message of response on MGC, the AS (is to find corresponding M2UA link collection for what adopt link set-link model) that can find this ASP to serve according to the ASP of correspondence; And current MGC goes up the configuration detection information (because at ASP side ASP for first transmission ASP UP message of this AS service) of also not preserving the opposite end among the corresponding A S, if comprise configuration detection information in the ASP UP ACK message of receiving, then the configuration detection information in the ASP UP ACK message preserved; Continue to send ASP ACTIVE message to the SG side;

Step S508: after the SG side had been received ASP ACTIVE message, response ASPACTIVE ACK message was given the ASP side, and both sides entered into business processing status after the ASP side was received ASP ACTIVE message;

Step S510: ASP2 sends ASP UP message and gives the SG side on MGC, and wherein including in the INFO String parameter (also can increase parameter newly) in the ASP UP message increases the local terminal configuration information;

Step S512: after receiving ASP UP message on the SG, can find the ASP (can be to find corresponding M2UA link for what adopt link set-link model) that on SG, disposes, and then the AS (can be to find corresponding M2UA link collection for what adopt link set-link model) that finds ASP to serve, and current SG goes up the configuration detection information of having preserved the opposite end among the corresponding A S, and also comprise configuration detection information among the message ASP UP that receives, then compare by the configuration detection information of having preserved the opposite end among configuration detection information in the ASP UP message of receiving and the last corresponding A S of SG, if the information that both comprise is identical, think that then two ends configurations mate, response ASP UP ACK message is to the ASP side; If the content difference that both comprise then needs to handle according to different situations:

● if the gateway support belongs to more, promptly a SG can have the ASP on a plurality of MGC to provide service for it, the configuration detection content that the last AS of possible different MG C sends is inequality, if SG can parse the content of configuration detection, therefrom distinguish MGC device identification and AS sign, then compare, if device identification is identical, ASP identifies different, just thinks configuration error has taken place, and can take some measures to stop the further interacting message in both sides; If can not resolve, then directly respond ASP UP ACK message; And

● if whether the gateway support or not many ownership, and then a SG has only an ASP on the MGC to provide service for it, just thinks configuration error has taken place, and can take some measures to stop the further interacting message in both sides.

The method that stops the further interacting message of both sides has a lot, can but be not limited to adopt similar the following measure:

● do not respond ASP UP ACK message, can output error message by SG side user intervention;

● respond a unexpected message such as message such as ERROR, NOTIFY, ASP DOWN ACK, can comprise error reason information in the message;

● response ASP UP ACK message, but comprised the configuration error message in the message perhaps is also contained in the configuration information of local terminal the ASP UP ACK message sent etc. and can informs that the parameter or the content of arrangement abnormalities have taken place in the opposite end; And

● remove the SCTP idol chain of setting up, can output error message.

If the last ASP2 of step S514:MGC sends ASP UP message and receives ASPUP ACK message later on, can do following processing respectively according to the content that comprises in the message:

● if comprised the configuration error message in the message, then output error message is reminded user intervention;

● there is not error message in the message, but the configuration information that has the opposite end, and current MGC goes up the configuration detection information of preserving the opposite end among the corresponding A S, then the configuration detection information by the opposite end of preserving among configuration detection information in the ASPUP ACK message and the last corresponding A S of MGC compares, if unanimity then continue to handle, if inconsistent, then output error message is reminded user intervention; And

● if not comprising configuration detection information in the message does not have error message yet, continues to send ASP ACTIVE message according to original processing.

Above-mentioned is a kind of giving an example, obviously, to those skilled in the art, actual disposition detects information except can being MGC device identification and the AS sign, can also be the combination that content that first-selected IP address of equipment unique identifying number, equipment or equipment place signalling point or other can marking equipments adds AS sign or link set identification, detect information simultaneously and can in any one message in ASP UP, ASP UP ACK, ASP ACTIVE, ASP ACTIVEACK, HeartBeat, the HeartBeat ACK message, carry; The opposite end receives that message also can carry out consistency check to the content in the message later on;

Obviously, to those skilled in the art, above process not only is applicable to M2UA, and other agreements of IUA, V5UA, M3UA, SUA or the like SIGTRAN also all are suitable for.

As can be seen from the above description, the present invention has realized following technique effect:

The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
