Abstract

The invention discloses a method for retrying roaming of a terminal call short message, comprising the steps that: in the process of transmitting a terminal call short message, a called mobile station (MS) moves to a new location area and transmits a location updating request to a new visitor mobile switching centre (VMSC)/visitor location register (VLR); the new VMSC/VLR forwards the location updating request to a home location register (HLR), and the HLR initiates a location area canceling request to an old VMSC/VLR; when the transmission of the terminal call short message on the old VMSC/VLR fails, a short message service gateway (SMS-GMSC) transmits a failure state report through a short message and informs the HLR that the transmission of the terminal call short message fails; and the HLR initiates a reminding process of the terminal call short message, and triggers a short message centre (SC) to retransmit the terminal call short message. Furthermore, the invention discloses a system for retrying roaming of the terminal call short message. According to the invention, the success rate and the timeliness for the transmission of the terminal call short message can be increased.

Description

Exhale the roaming retry method and the system of short message a kind of end
Technical field
The present invention relates to the moving communicating field roaming technology, relate in particular to the roaming retry method and the system of exhaling short message a kind of end.
Background technology
3G (Third Generation) Moblie technology (3G, 3rd Generation) core network is by (the MSC of mobile switching centre, Mobile Switching Center), VLR Visitor Location Register (VLR, Visitor LocationRegister), attaching position register (HLR, Home Location Register) and radio network controller (RNC, Radio Network Controller) form.Wherein, MSC can be divided into gateway MSC (GMSC according to function, Gateway Mobile Switching Center) and Visited Mobile Switching Center (VMSC, Visitor Mobile Switching Center), GMSC is the MSC that is responsible for inquiry called subscriber routing iinformation, and VMSC is that user's visit MSC calls out the destination that will be routed to; VLR is user's a VLR Visitor Location Register, and HLR is user's a attaching position register, and RNC is a network element of being responsible for finishing the user radio access function.Short message is similar with calling, also needs could determine the destination that short message will send to through routing inquiry, and the gateway exchange of being responsible for inquiry short message route is called short messaging gateway (SMS-GMSC, SMS-Gateway Mobile Switching Center).
The user sent rises and exhales short message to be stored by the short message service center (SC, ShortMessage Center) that VMSC sends to the user.SC is a place that short message is transmitted in storage, because the calling subscriber is when sending SMS message, the called subscriber may shut down also may out of reach, and this moment, SC just played effect temporary, that transmit short message.SC has received and has exhaled after the short message, can earlier this short message be kept in, and short message is transmitted to SMS-GMSC, this SMS-GMSC can be according to the called subscriber's who carries in the short message number, be initiated to the routing inquiry of the SMS terminal call of HLR, HLR returns to SMS-GMSC with the MSC number (Number) of the VMSC at the current place of called subscriber; SMS-GMSC will exhale short message to be transmitted to called mobile station (MS, Mobile Station) by this VMSC with exhaling the short message route to give the VMSC at called subscriber place eventually again end then.
In the prior art, exhale short message to send successful flow process as shown in Figure 1 eventually, mainly may further comprise the steps:
Step 101, SC will exhale short message to be transmitted to SMS-GMSC by the request of sending SMS message end.
Step 102, SMS-GMSC sends SMS message routing inquiry request to HLR, the MSC Number at the current place of inquiry called subscriber.
Step 103, HLR returns to SMS-GMSC with the MSC Number at called subscriber place by the response of short message routing inquiry.
Step 104, the MSC Number that SMS-GMSC obtains with the response of short message routing inquiry does global title (GT, Global Title) translation, and request message will exhale short message to be transmitted to VMSC/VLR end by sending SMS message.
Step 105, VMSC/VLR finish exhaled the short message scope check called subscriber's end after, called MS is initiated paging (Paging) request.
Step 106, called MS is returned Paging and is responded to VMSC/VLR.
Step 107, VMSC/VLR will exhale short message to be transmitted to called MS by the request message that sends SMS message end.
Step 108, called MS are returned to VMSC/VLR and are exhaled an end short message to send response message, and notice VMSC/VLR exhales short message to send successfully eventually.
Step 109, VMSC/VLR returns to SMS-GMSC and exhales an end short message to send response message, and notice SMS-GMSC exhales short message to send successfully eventually.
Step 110, SMS-GMSC returns the response message that sends SMS message and gives SC, and notice SC short message service center exhales note to send successfully eventually; After SC received and sends successful response message, the correspondence (promptly having sent successful) that deletion is preserved was exhaled short message eventually.
Describe as can be seen from above-mentioned flow process, the user has two kinds may be moved in the process of exhaling short message to send eventually, a kind of may be between the step 105 in step 103, the user may move to below other VMSC/VLR, thereby cause when VMSC/VLR receives that exhale the short message request end of SMS-GMSC transmission, can not finding user data, cause the failure of user's absence, general because 104 steps are very fast, therefore this possibility is less; Another kind may be between the step 106 in step 105, VMSC/VLR is between to called subscriber's paging periods, the called subscriber moves to below other VMSC/VLR, because the paging time is longer, therefore the high mobility user might move to below other VMSC/VLR very much in this process, this situation can cause paging failure, also can cause owing to paging failure causes short message and send failure; The flow process that like this will triggering short message sends failure, the flow process that sends failure at preceding a kind of short message mainly may further comprise the steps as shown in Figure 2:
Step 201, SC will exhale short message to be transmitted to SMS-GMSC by the request of sending SMS message end.
Step 202, SMS-GMSC sends SMS message routing inquiry request to HLR, the MSC Number at the current place of inquiry called subscriber.
Step 203, HLR returns to SMS-GMSC with the MSC Number at called subscriber place by the response of short message routing inquiry.
Step 204, during SMS-GMSC carried out the short message routing inquiry, called MS moved to below the new VMSC/VLR, and initiated position updating request to new VMSC/VLR.
Step 205 after new VMSC/VLR receives the location update request message of called MS initiation, is initiated the position updating request process to HLR.
Step 206, HLR initiates canceling position district's request to old VMSC/VLR after receiving the location update request message of user below new VMSC/VLR.
Step 207, after old VMSC/VLR received canceling position district request message, these user-dependent data of deletion local exchange were returned canceling position district response message then and are given HLR.
Step 208 after HLR receives the canceling position district response message that comes from old VMSC/VLR, is upgraded success response to new VMSC/VLR home position.
Step 209, at this moment, the MSC Number that SMS-GMSC obtains with the response of short message routing inquiry does the GT translation, and request message will exhale short message to be transmitted to old VMSC/VLR end by sending SMS message.
Step 210 after old VMSC/VLR receives this short message, has been gone because the possibility user moves among the new VMSC/VLR, and exhale short message to fail the end that therefore user's absence may take place this moment; Old VMSC/VLR returns the failure response that sends SMS message and gives SMS-GMSC.
Step 211 because after exhaling eventually short message to send failure, need and can triggering short message remind (Alert) process after user Ke Da or internal memory empty, so SMS-GMSC need send SMS message status report to HLR.
Step 212 after HLR receives the short message status report, is noted the short message that the failure of sending is once arranged, and waits the user to insert again or after internal memory empties, prepares to notify corresponding SC to resend and exhale short message eventually; HLR finishes above-mentioned action and returns a short message status report response message later on to SMS-GMSC.
Step 213, SMS-GMSC returns the failure response message that sends SMS message and gives SC; Exhaling short message to send failure procedures eventually finishes.
Another kind causes exhaling eventually short message to send failure owing to the user moves then be between paging periods, because the time of paging may be longer, the user may move to new VMSC/VLR at this moment, thereby cause that short message sends failure; Corresponding flow chart mainly may further comprise the steps as shown in Figure 3:
Step 301, SC will exhale short message to be transmitted to SMS-GMSC by the request of sending SMS message end.
Step 302, SMS-GMSC sends SMS message routing inquiry request to HLR, the MSC Number at the current place of inquiry called subscriber.
Step 303, HLR returns to SMS-GMSC with the MSC Number at called subscriber place by the response of short message routing inquiry.
Step 304, the MSC Number that SMS-GMSC obtains with the response of short message routing inquiry does the GT translation, and request message will exhale short message to be transmitted to old VMSC/VLR end by sending SMS message.
Step 305, this moment, called MS began to move to below the new VMSC/VLR, and initiated position updating request to new VMSC/VLR.
Step 306, old VMSC/VLR begins to initiate the paging request after receiving and exhaling the short message request message eventually.
Step 307 after new VMSC/VLR receives the location update request message of called MS initiation, is initiated the position updating request process to HLR.
Step 308, HLR receives that the user after the location update request message under the new VMSC/VLR, initiates canceling position district's request to old VMSC/VLR.
Step 309, after old VMSC/VLR receives canceling position district request message, these user-dependent data of deletion local exchange, and end ongoing paging, return canceling position district response message then and give HLR.
Step 310, HLR receives after the canceling position district response message that comes from old VMSC/VLR, upgrades success response to new VMSC/VLR home position.
Step 311 after old VMSC/VLR receives the request of canceling position district, is ended ongoing paging; Old VMSC/VLR returns the failure response that sends SMS message (paging failure) and gives SMS-GMSC.
Step 312 because after exhaling eventually short message to send failure, need can be after user Ke Da or internal memory empty triggering short message Alert process, so SMS-GMSC need send SMS message status report to HLR.
Step 313 after HLR receives the short message status report, is noted the short message that the failure of sending is once arranged, and waits the user to insert again or after internal memory empties, prepares to notify corresponding SC to resend and exhale short message eventually; HLR finishes above-mentioned action and returns a short message status report response message later on to SMS-GMSC.
Step 314, SMS-GMSC returns the failure response message that sends SMS message and gives SC; Exhaling short message to send failure procedures eventually finishes.
This shows that prior art the user occurs and moves to situation other VMSC/VLR under for exhaling eventually in the short message process, can not initiate to exhale end short message timely and effectively.Exhale short message Alert process to occur in after the position updating request that HLR receives the user eventually, HLR checks the record that whether has overstocked short message to send failure, just notifies SC to resend this short message if having; Because when the user carries out the position renewal at new VMSC/VLR, exhale current end the flow process of short message also not finish, therefore can not trigger the Alert process of exhaling short message eventually this moment, must wait until when the user initiates business next time, just can trigger the Alert process of exhaling short message eventually, will influence the ageing and success rate of exhaling short message issuing eventually like this.
