Embodiment
Method embodiment one
In the present embodiment, provide a kind of calling implementation method.This method goes to consider from angle more fully how SMSC should obtain routing iinformation, and guarantees the availability and the validity of these routing iinformations as far as possible.The realization approach of this calling implementation method is to write down first user and second user's routing iinformation when carrying out MO and two kinds of flow processs of MT respectively.By this method can reduce to a great extent short message issuing to the influence of mobile network's load, reduce short message service center to the complete dependence of HLR, strengthen the traffic handing capacity of short message service center.
At present, the current routing iinformation of user can obtain by following two modes: (1) obtains when the user initiates MO action, (2) obtain when receiving the SRI response that HLR returns.
In addition, according to the custom that the user sends SMS message usually, after first user sent SMS message for second user, second user generally can reply a short message within a short period of time first user after receiving short message again.And, the scope of MSC administration is bigger, after the user sends a short message or receives a short message, is the scope that is difficult to shift out this MSC administration at short notice, unless this user just in time is in the border of MSC administration, but this probability is less.
Therefore, can think when the user sends SMS message or correctly receives a short message, if can send to SMSC to this routing iinformation, another user is to the short message of his transmission so within a certain period of time, SMSC still can use this routing iinformation short-message sending under this user, and need not HLR inquiry route, and accuracy is very high.
Further, the routing iinformation effect that particularly writes down first user when initiating the MO action is best because according to 3GPP standard SMSC after short message being delivered on second user mobile phone, send bar state report can for first user.Generally speaking, when issuing success rate first than higher the time, status report sends and source message initiate MO the time at interval all can be very short, therefore, first user's routing iinformation that can write down when initiating the MO action issue status report fully.
The present invention just provides a kind of calling implementation method based on above-mentioned consideration, to solve the problem that the excessive and short message service center of HLR load in the correlation technique relies on HLR fully.
Describe the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, comprise: step S102, first user's who makes a call in short message service center's storage first routing iinformation and/or store second user's of first customer call secondary route information according to the calling implementation method of the inventive method embodiment; It is mutual that step S104, first user and second user utilize first routing iinformation of short message service center storage and/or secondary route information to carry out follow-up.
Wherein, the short message service center storage first via is specially by information processing: rise when exhaling first user who makes a call, first user's first mobile switching centre/first VLR Visitor Location Register is notified to intercommunication mobile switching centre with first user's first routing iinformation; Intercommunication mobile switching centre sends to short message service center with first routing iinformation, and short message service center preserves first routing iinformation.
Particularly, first mobile switching centre/first VLR Visitor Location Register is specially the processing that first routing iinformation is notified to intercommunication mobile switching centre: first mobile switching centre/first VLR Visitor Location Register sends to intercommunication mobile switching centre by waiting the short message of sending out with first routing iinformation.Particularly, first mobile switching centre after sending signaling MAP_MO_FORWARD_SHORT_MESSAGE, sends to short message service center with the sign of mobile switching centre when sending the MAP_OPEN signaling to GMSC (gateway mobile switching center).
After receiving the short message of forwarding, intercommunication mobile switching centre obtains first routing iinformation from short message, and asks message that first routing iinformation is notified to short message service center by rising to call for.Particularly, can add field RouteInfoFlag and RouteInfo in the message rising to call for to ask, wherein, RouteInfoFlag is used for representing whether message has carried routing iinformation, and RouteInfo is used to represent the routing iinformation that specifically carries.More specifically, can be not carry routing iinformation in the 0 expression message with the RouteInfoFlag value, the RouteInfoFlag value is to have carried routing iinformation in the 1 expression message.
And after short message service center preserves first routing iinformation, further comprise: short message service center sends to intercommunication mobile switching centre with response message; Intercommunication mobile switching centre sends to first mobile switching centre/first VLR Visitor Location Register with short message transmitted response message; First mobile switching centre/first VLR Visitor Location Register will rise exhales response message to send to first user.
GMSC (gateway mobile switching center) carries out exhaling end, and the processing that secondary route information is sent to short message service center is specially: GMSC (gateway mobile switching center) will wait that the short message of sending out sends to second mobile switching centre/second VLR Visitor Location Register of second user; Second mobile switching centre/second VLR Visitor Location Register carries out exhaling end to second user; Second mobile switching centre/second VLR Visitor Location Register receive from after second user's the response to the GMSC (gateway mobile switching center) transmitted response that sends SMS message; GMSC (gateway mobile switching center) sends to short message service center with secondary route information by exhaling response eventually.Particularly, GMSC (gateway mobile switching center) is issued the end of short message service center and is exhaled in the corresponding message, exhale flow process similar with rising, exhaling in the flow process eventually, same field RouteInfoFlag and the RouteInfo of adding, and RouteInfoFlag is used for representing whether message has carried routing iinformation, and RouteInfo is used to represent the routing iinformation that specifically carries.More specifically, can be not carry routing iinformation in the 0 expression message with the RouteInfoFlag value, the RouteInfoFlag value is to have carried routing iinformation in the 1 expression message.
In addition, short message service center's storage secondary route information processing is specially: short message service center initiates to exhale eventually to GMSC (gateway mobile switching center) according to second user's secondary route information, and by exhaling response message that secondary route information is sent to short message service center eventually, short message service center stores secondary route information.
And after short message service center has preserved secondary route information, further comprise: first user and second user carry out follow-up mutual calling according to first routing iinformation and the secondary route information of preserving.
In addition, when first user and second user carried out follow-up mutual calling, second user's of follow-up mutual calling routing iinformation carried in short message service center in the final call request of its initiation.
Preferably, when short message service center initiates to exhale eventually, further comprise:, then do not carry routing iinformation (concrete signaling shows as and makes RouteInfoFlag=0) in the final call request message that GMSC (gateway mobile switching center) is initiated, the routing iinformation sign being changed to if short message service center does not preserve second user's routing iinformation; GMSC (gateway mobile switching center) is searched second user's routing iinformation at second user's attaching position register.
Preferably, when short message service center initiates to exhale eventually, further comprise:, then carry routing iinformation (concrete signaling shows as and makes RouteInfoFlag=1) in the final call request message that GMSC (gateway mobile switching center) is initiated, the routing iinformation sign being changed to if short message service center has preserved second user's routing iinformation; GMSC (gateway mobile switching center) is carried out the short message forwarding according to second user's routing iinformation.
Preferably, the first via is comprised the sign of first user's international mobile subscriber identity and first mobile switching centre/first VLR Visitor Location Register by information; Secondary route information comprises the sign of second user's international mobile subscriber identity and second user's second mobile switching centre/second VLR Visitor Location Register.
Particularly, Fig. 2 shows in actual application calling implementation method according to the present invention is obtained user's routing iinformation on the MO flow process signaling process.Wherein, by extracting first user's routing iinformation, and at this interim routing iinformation of the inner record of SMSC, can be so that second user be when postbacking short message for first user, SMSC can be directly obtains first user's interim routing iinformation in self inside, and needn't inquire about first user's routing iinformation, thereby reduced the load of HLR to HLR.As shown in Figure 2, specifically may further comprise the steps:
Step 201, MS sends MO and asks MSC to its present place;
Step 202, MSC is transmitted to IWMSC to the short message that the user submits to, and preferably, two signalings of use can be respectively MAP_OPEN and MAP_MO_FORWARD_SHORT_MESSAGE;
Step 203, IWMSC notes the address of MSC when receiving MAP_OPEN, receives then to be decoded into behind the MAP_MO_FORWARD_SHORT_MESSAGE and the rising to call for and ask of the inner agreement of SMSC.Then judge whether carried the IMSI number in the request message (whether carrying according to 3GPP 09.02 standard IMSI is an option), if carried IMSI, RouteInfoFlag is set to 1 in calling for for rising of SMSC to ask so, and IMSI number and MSC assignment to RouteInfo;
Step 204, IWMSC asks response to send to SMSC rising to call for;
Step 205, SMSC receive rising of IWMSC call for ask after, judge in the request whether carried routing iinformation, if carry (RouteInfoFlag=1), so routing iinformation is sent to inner routing management module; Then SMSC carries out normal short message original calling flow processing;
Step 206, SMSC finished exhale flow processing after, sent and exhaled response;
Step 207, IWMSC returns the short message transmitted response and gives MSC (that is, above-mentioned a MSC);
Step 208, MSC returns MO and responds to MS.
Fig. 3 shows the signaling process that uses interim routing iinformation and preserve the routing iinformation that upgrades in actual applications according to calling implementation method of the present invention on the MT flow process.Wherein, by SMSC from self inner inquiry and obtain second user's secondary route information, can be so that SMSC initiates needn't inquire about secondary route information to HLR before the MT flow process initiates for second user; And after the MT flow process was finished, the secondary route information after will being upgraded by GMSC sent to SMSC, and preserves this secondary route information by SMSC.The execution of this flow process can reduce effectively HLR load, reduce the dependence of SMSC to HLR.
As shown in Figure 3, specifically comprise following processing procedure:
Step 301, SMSC short-message sending final call request is given GMSC, and, SMSC is before initiating this final call request, at first inquire about the interim routing iinformation whether himself inside records second user, if put down in writing, then in this SMS terminal call request, carry this interim routing iinformation, otherwise then do not carry routing iinformation;
Step 302, GMSC judges whether carry routing iinformation in the final call request, if judged result for carrying (RouteInfoFlag=1), execution in step 305 so, if judged result is for not carrying (RouteInfoFlag=0) then continue execution in step 303;
Step 303, alternatively, GMSC can initiate the MAP_SEND_ROUTING_INFO_FOR_SM signaling to HLR and obtain the current routing iinformation of second user (that is secondary route information);
Step 304, HLR returns the present routing iinformation of second user to GMSC;
Step 305, GMSC is transmitted to short message the MSC (that is above-mentioned the 2nd MSC) at the second user place afterwards according to this routing iinformation (this information is carried or obtained from HLR from SMSC) by the MAP_MT_FORWARD_SHORT_MESSAGE instruction;
Step 306 after MSC receives MAP_MT_FORWARD_SHORT_MESSAGE instruction, is checked second user whether in the scope of own administration, if do not exist, then processing proceeds to step 309, if would continue execution in step 307;
Step 307, MSC transmits the MT request and short message is sent to MS;
Step 308, MS returns the MT response;
Step 309, MSC returns the forwarding short message and responds to GMSC;
Step 310, GMSC carries secondary route information and sends it to SMSC whole exhaling in the response;
Step 311, SMSC preserves this second user routing iinformation after exhaling response the end of receiving the routing iinformation that carries second user.
Further and since in step 301 SMSC inner what obtain is interim routing iinformation from self, but not definite routing iinformation of returning by HLR, so this routing iinformation can't reflect the MSC at present user place very definitely.So when carrying out step 306, MSC may find that the second customer objective ground is not in the compass of competency of oneself.For this situation, when execution in step 310, SMSC will receive and exhale response the end of a failure that SMSC need continue to issue this short message and promptly begin to carry out processing from step 302 again at this moment, does not still carry the interim routing iinformation of second user from self inner acquisition.
The structure of SMSC as shown in Figure 4, it comprises professional total activation module, database module, performance statistic module, accounting module, webmaster module, and when realizing above-mentioned processing procedure of the present invention, can set up routing management module to SMSC, and route administration module and SMSC are carried out following configuration:
Add phone number (MSISDN), routing iinformation and the route term of validity that a memory table is preserved user's user at SMSC, wherein, routing iinformation comprises the address (sign) of IMSI and user place MSC;
Routing management module is configured to have discerned field RouteInfoFlag and the RouteInfo that calls in asking, when RouteInfoFlag is 1, routing iinformation is saved in the above-mentioned memory table;
Wherein, SMSC can discern field RouteInfoFlag and the RouteInfo that exhales eventually in the response, when RouteInfoFlag be 1 and response be successfully the time, routing iinformation is saved in the memory table;
When short message will carry out MT, arrive first in the memory table and find relevant routing iinformation according to MSISDN; Still routing iinformation is expired if can not find or found, and then gives in the final call request message of GMSC, and RouteInfoFlag is set to 0;
When finding routing iinformation and routing iinformation not out of date, then give in the final call request message of GMSC, RouteInfoFlag is set to 1 and carry routing iinformation.
In following scene, by the calling implementation method of using present embodiment to provide, the efficient that the short message network can either improve short message issuing can guarantee to issue success rate again, thus reduced effectively HLR load, reduced the dependence of SMSC to HLR:
The first, SMSC gives in the scene of first user's recoil state report, especially, is after first user descends short-message sending first, and in the scene of SMSC recoil state report, SMSC uses interim routing iinformation can obtain very high transmission success rate.At this moment, because in the flow process of initiating MO, SMSC has preserved first user's routing iinformation, so SMSC can directly use the interim routing iinformation of first user of portion's preservation within it when giving the report of first user's recoil state.Because the time interval from MO flow process successful execution to the status report flow process, in the so short time, the user was minimum from the probability that a MSC moves to another MSC about 10 seconds; So the method that present embodiment provides will greatly improve the success rate of short message issuing;
The second, at heavy traffic period, in the scene that has a plurality of users to send SMS message to same user in a short time, SMSC uses interim routing iinformation can obtain very high transmission success rate.Such as, when sent the blessing short message Spring Festival, its characteristics were exactly that the user can receive blessing short message from different people in the short period of time.In addition, in traffic peak, generally also can follow more speech business, HLR must be in a higher load condition so.SMSC uses interim routing iinformation can greatly reduce the load of HLR;
In the scene of chatting by short message mutually between the three, two user, SMSC uses interim routing iinformation can obtain very high transmission success rate.Caller and called between will inevitably send short message several times mutually back and forth.Use interim routing iinformation by SMSC, these short messages will obtain the very high success rate that issues.
