In the existing SMC dividing technology, (MO for the terminal initiation, Mobile Originated) short message, in signaling network according to the IMSI International Mobile Subscriber Identity (IMSI of caller mobile phone, InternationalMobile Subscriber Identity) number carries out route, so can be responsible for service distributing and switching by Signalling Transfer Point (STP, Signaling Transfer Point).As former SMC and dilatation SMC all during operate as normal, STP according to different global title (GT, Global Title) with service distributing to two SMC.

(MT for the terminal termination, Mobile Terminated) short message, if the SMC of professional recipient and professional transmit leg ownership is not same SMC, the SMC of so professional transmit leg ownership sends point-to-point (SMDPP by short message, Short Message Delivery Point to Point) or the point-to-point (SMPP of short message, Short Message Point to Point) interface, this short message is forwarded to the SMC that professional recipient belongs to, and is issued to professional recipient by the SMC of professional recipient's ownership.

When professional recipient cannot use or be unreachable, existing short message transmission method specifically comprised:

SMC receives the short message that professional transmit leg is submitted to, whether the professional recipient who inquires about this short message is the user who belongs to self, if, then to attaching position register (HLR, Home LocationRegister) service request (SMSREQUEST) message that sends SMS message, inquire about the mobile switching centre (MSC, Mobile Switching Center) of this business recipient ownership; If it is not the user who belongs to himself that SMC inquires this business recipient, then by SMDPP or SMPP interface, this short message is forwarded to the SMC that professional recipient belongs to, and the SMC of professional recipient's ownership sends SMSREQUEST message to HLR, the MSC of inquiry business recipient's ownership.

If HLR detects the user and cannot use, then the SMC to professional recipient's ownership replys the information that the user cannot use, and after the user can use, sends the operable notice of this user to the SMC of this business recipient ownership; SMC is by sending point-to-point (SMSDPP, SMS Delivery Point to Point) message to the MSC of this business recipient ownership business of sending SMS message then, and the short message that will send sends to this MSC, is issued to professional recipient by this MSC.

In the short-message sending process, unreachable if MSC sends the user, then the SMC to professional recipient's ownership replys the inaccessible information of user to MSC under professional recipient; Behind user Ke Da, send the notice of user Ke Da to the SMC of professional recipient's ownership; The SMC of professional recipient's ownership is after the notice that receives user Ke Da, once more by this MSC short-message sending under professional recipient.

As seen, in the short message transmission process of existing C DMA/TDMA network, the message interaction process complexity belongs to Home Network but belongs to when sending SMS message between the user of two SMC and need transmit once, has increased unnecessary transmission time-delay.

Below with three embodiment technical scheme of the present invention is described in detail.

Embodiment one:

In the present embodiment, when HLR detect the user by cannot use change into can use after, send the operable notice of user to the SMC of user attaching, this SMC has the function of the operable notice of this user of broadcasting.

Fig. 1 is the method flow diagram of short message transmission in the embodiment of the invention one.As shown in Figure 1, this method may further comprise the steps:

Step 100: the SMC of professional its ownership of sending direction submits short message to.

Step 101:SMC is to the MSC of HLR inquiry business recipient ownership.

In this step, SMC is to the HLR request of sending SMS message (SMSREQUEST), the MSC of inquiry business recipient's ownership.

Step 102:HLR detects the user cannot use the time, replys the information that this user of SMC cannot use.

For example when the user shuts down, can close machine information to the HLR registration.In this step, as SMC during to HLR inquiry business recipient's ownership MSC, HLR can detect this user's shutdown, and replys the information that this user cannot use to SMC.

In this step, HLR detects the user and cannot use, and comprises that the user shuts down or the unavailable User Status such as (for example subscriber arrearages) of user need be at the state of HLR registration when changing.

SMC saves short message after receiving the information that professional recipient cannot use, and waits for issuing this short message again.

Step 103:HLR changes into can use the time by using detecting User Status, sends the operable notice of this user to the SMC of this user attaching, wherein carries the MSC information of this user attaching.

Operable notice comprises user's startup notifying or available notification etc., is that the user changes into the notice that can use the back to be sent by HLR at the HLR enrollment status.

Step 104: the SMC of user attaching is after receiving the operable notice of professional recipient, and other SMC broadcasts this notice in the Home Network that sets in advance.

In this step, the SMC of professional recipient ownership receive this user can use notice after, utilize watchful notice (ALERT_NOTIFICATION), can use notification message to be broadcast to other SMC this user.

In this step, other SMC is meant when building SMC in the Home Network that sets in advance, and preserves the number of other SMC in the Home Network in each SMC.

Step 105: all receive the SMC that this user can use notification message, wait for the short message that is issued to this user if having, and then the MSC to professional recipient's ownership sends SMS message.

If do not have to wait for the short message that is issued to this user, then ignore ALERT_NOTIFICATION message.

Step 106: the MSC of professional recipient's ownership arrives professional recipient with short message issuing.

Step 103～step 104 can be carried out before or after above-described other arbitrary step.

Fig. 2 is the system construction drawing of short message transmission in the embodiment of the invention one.As shown in Figure 2, this system comprises: professional transmit leg belongs to SMC, professional recipient belongs to SMC, HLR and professional recipient belongs to MSC.

Wherein, professional transmit leg ownership SMC is used to receive the short message that professional transmit leg is submitted to, inquires about the MSC of this short message service recipient ownership; When receiving the information that professional recipient cannot use, preserve described short message; And the SMC broadcasting that receives described professional recipient ownership carry professional recipient belong to MSC information can use notice the time, belong to MSC by professional recipient and issue this short message.

The SMC of professional recipient's ownership is used for can using notice to what all SMC broadcasting that set in advance carried that professional recipient belongs to MSC information.

Professional recipient belongs to the short message that SMC that MSC is used to receive professional transmit leg ownership sends, and is issued to professional recipient.

Whether this system also can further comprise HLR, be used to detect professional recipient and can use, and when professional recipient cannot use, sends the information that professional recipient cannot use to the SMC of professional transmit leg ownership; Change into can use the time by using professional recipient, send the operable notice of professional recipient, wherein carry the MSC information of professional recipient's ownership to the SMC of professional recipient's ownership.

Specifically, the SMC in the present embodiment comprises:

Memory module is used to the SMC number that saves short message and set in advance;

Control module is used for when receiving the information that professional recipient cannot use, and the notice memory module is preserved this short message; Receiving after professional recipient belongs to the operable notice of professional recipient of SMC broadcasting, the notice sending module issues this short message;

Sending module is used to issue the short message that is kept at memory module;

And broadcast module, be used for after receiving the operable notice of professional recipient that HLR sends, with this notification broadcast to all SMC that set in advance.

The SMC of wherein professional recipient's ownership can not comprise the dotted portion (broadcast module and dotted arrow) among the figure.

As seen, when SMC received short message in the present embodiment, no matter whether the professional recipient of this short message belonged to this SMC, all the MSC of this short message by professional recipient's ownership directly can be issued to professional recipient; When the user changes into can use the time by using, receive SMC that the user can use notice with this notification broadcast other SMC in the Home Network, make to clamp on that the SMC of short-message sending descends short-message sending again under this user.Therefore simplify the flow process of short message transmission, avoided transmission delay.

Embodiment two:

In the present embodiment, changed into can reach the time by unreachable when MSC detects the user, MSC sends user's reached at notice to the SMC of user attaching, and this SMC has the function of this user Ke Da notice of broadcasting.

Fig. 3 is the method flow diagram of short message transmission in the embodiment of the invention two.As shown in Figure 3, this method may further comprise the steps:

Step 300～step 301 is identical with step 100～step 101, does not repeat them here.

Step 302～step 304:SMC sends SMS message to the MSC of professional recipient's ownership behind the MSC of the professional recipient's ownership that receives the HLR transmission; When MSC detect professional recipient unreachable after, send the inaccessible information of professional recipient to SMC.

SMC sends SMSDPP message to MSC, notifies short-message sending under this MSC.When subscriber absent can't receive information, it is unreachable that MSC detects this user.

Step 305: the MSC of professional recipient ownership detect professional recipient by unreachable become can reach after, send the notice that professional recipient can reach to the SMC of professional recipient's ownership.

Step 306: receive SMC other SMC in the Home Network that sets in advance that professional recipient can reach notice and broadcast this notice.

Step 307～step 308 is identical with step 105～step 106, does not repeat them here.

Fig. 4 is the system construction drawing of short message transmission in the embodiment of the invention two.As shown in Figure 4, this system comprises that the SMC and the professional recipient of the SMC of professional transmit leg ownership, professional recipient ownership belong to MSC.

Wherein, the SMC of professional transmit leg ownership is used to receive the short message that professional transmit leg is submitted to, inquires about the MSC of this short message service recipient ownership; When receiving the inaccessible information of professional recipient, preserve this short message; And when the notice that the professional recipient of the SMC broadcasting that receives professional recipient ownership can reach, belong to MSC by professional recipient and issue this short message;

The SMC of professional recipient's ownership is used for the notice that can reach to all SMC broadcasting service recipients that set in advance;

The MSC of professional recipient's ownership is used to receive the short message that the SMC of professional transmit leg ownership sends, and detect professional recipient and whether can reach, can reaching at present professional recipient, short-message sending arrives professional recipient, when professional recipient is unreachable, send the inaccessible information of professional recipient to the SMC of professional transmit leg ownership; Become can reach the time by unreachable detecting professional recipient, send the notice that professional recipient can reach to the SMC of professional recipient's ownership, and with the short message issuing that receives to professional recipient.

This system also or comprise HLR is used for sending to the SMC of professional transmit leg ownership the MSC information of professional recipient's ownership.

Specifically, the SMC in the present embodiment comprises:

Control module is used for when receiving the inaccessible information of professional recipient, and the notice memory module is preserved the short message that receives; Receiving after professional recipient belongs to the notice that the professional recipient of SMC broadcasting can reach, the notice sending module issues this short message;

And broadcast module, be used for after receiving the notice that professional recipient that MSC sends can reach, with this notification broadcast to all SMC that set in advance.

As seen, when SMC received short message in the present embodiment, no matter whether the professional recipient of this short message belonged to this SMC, all the MSC of this short message by professional recipient's ownership directly can be issued to professional recipient; When the user is changed into can reach the time by unreachable, the SMC that receives user Ke Da notice is this notification broadcast other SMC in the Home Network, and the SMC that making clamps on issues short message descends short-message sending again.Therefore simplify the flow process of short message transmission, avoided transmission delay.

Embodiment three:

In the present embodiment, when SMC when HLR inquiry business recipient belongs to MSC, HLR detects professional recipient's User Status for using, for example user's shutdown, then User Status revert to can use after, apply for this business recipient's the SMC that can use notice to this SMC or all, send the operable notice of this business recipient.

Fig. 5 is the method flow diagram of short message transmission in the embodiment of the invention three.As shown in Figure 5, this method may further comprise the steps:

Step 500: its ownership of professional sending direction SMC submits short message to.

Step 501:SMC is to the MSC of HLR inquiry business recipient ownership.

In this step, SMC is to the HLR request of sending SMS message (SMSREQUEST), the MSC of inquiry business recipient's ownership; And the short message notification among SMSREQUEST indication (SMS_NotificationIndicator) parameter is set to 1, applies for the operable notice of this user.

The User Status that step 502:HLR detects professional recipient for cannot use the time, notice SMC, and write down this SMC number or all apply for the SMC number of the operable notice of this business recipient; After this business recipient can use, to the SMC of the operable notice of application this business recipient of all records, send this business recipient's operable notice, wherein carry the MSC information of this business recipient ownership.

For example when the user shuts down, can close machine information to the HLR registration.In this step, as SMC during to HLR inquiry business recipient's ownership MSC, HLR can detect this user's shutdown, at this moment, HLR gets off the number record of this SMC, if have other SMC also applied for should the business recipient startup notifying, then store the number of each SMC and the corresponding relation of professional recipient's number.When user start when HLR registers, HLR detects the user and can use, and notes to all, applies for that the SMC of this user's startup notifying sends this user's startup notifying.

In this step, HLR detects the user and cannot use, and comprises that the user shuts down or the unavailable User Status such as (for example subscriber arrearages) of user need be at the state of HLR registration when changing.Operable notice comprise users such as user's startup notifying or available notification the HLR enrollment status change into can use after, the notice that sends by HLR.

Step 503:SMC sends SMS message to the MSC of its ownership after receiving professional recipient's operable notice.

Step 504: MSC short-message sending under professional recipient of professional recipient's ownership.

Can normally receive short message if HLR detects professional recipient, the process that then sends the operable notice of user in the step 502 can be omitted.

As seen from the above description, whether the SMC that receives short message in the present embodiment no longer inquiry business recipient is the user who belongs to himself, but directly inquires about the MSC of this user attaching to HLR, and issues this short message by this ownership MSC.That is to say no matter whether professional recipient is the user who belongs to himself, the SMC that receives short message can be responsible for issuing of this short message, and need not carry out short message issuing by the SMC of professional recipient's ownership.Therefore, simplified message interaction process, do not existed and transmit time-delay, and increased professional reliability.

Simultaneously, the operable message of user also can send to this user of application by HLR can use the SMC of notice, can't be owing to there not being the operable notice of user, return to can use the time by using in User Status, and can't descend short-message sending.

Because the short message that dilatation SMC can send the user who belongs to himself all directly is issued to professional recipient, need not transmitted by other SMC, therefore, has realized dilatation truly; At last, have only the SMC of following short-message sending successful service transmit leg ownership to generate a ticket, thereby can not produce the chaotic problem of chargeing.

Embodiment four:

In the present embodiment, when SMC when MSC sends SMS message, MSC finds that short message service recipient's User Status is unreachable, then behind this user Ke Da, sends user Ke Da notice to SMC.

Fig. 6 is the method flow diagram of short message transmission in the embodiment of the invention four.As shown in Figure 6, this method may further comprise the steps:

Step 600: the SMC of professional its ownership of sending direction submits short message to.

Step 601:SMC is to the MSC of HLR inquiry business recipient ownership.

Step 602:HLR returns the MSC of professional recipient's ownership to SMC.

Step 603:SMC sends SMS message to the MSC of professional recipient's ownership.

In this step, SMC sends SMSDPP message to MSC, notifies short-message sending under this MSC.And the SMS_NotificationIndicator parameter among the SMSDPP is set to 1, applies for professional recipient's reached at notice.

Step 604:MSC finds that professional recipient's User Status is unreachable, then reply the inaccessible information of this user of SMC, and write down the number of this SMC or all apply for the SMC number of this user Ke Da notice, and behind this user Ke Da, send this user's reached at notice to the SMC of this user Ke Da notice of all needs of noting.

In this step, for example when subscriber absent can't received signal, it is unreachable that MSC detects this user, then the number record with this SMC center gets off, if reached at the notice that has other SMC also to apply for this user then simultaneously corresponding to this business recipient, writes down the number of each SMC.When the user Ke Da, note to all, apply for that the SMC of this user Ke Da notice sends this user's reached at notice.

Step 605:SMC sends SMS message to the MSC of professional recipient's ownership after reached at the notice that receives professional recipient.

Step 606: the MSC of professional recipient's ownership arrives professional recipient with short message issuing.

In the present embodiment, for can reach the time, the MSC of professional recipient's ownership can directly be issued to professional recipient with short message in professional recipient's User Status.

As seen from the above description, whether the SMC that receives short message in the present embodiment no longer inquiry business recipient is the user who belongs to himself, but directly inquires about the MSC of this user attaching to HLR, and issues this short message by the MSC of professional recipient's ownership.That is to say no matter whether professional recipient is the user who belongs to himself, the SMC that receives short message can be responsible for issuing of this short message, and need not carry out short message issuing by the SMC of professional recipient's ownership.Therefore, simplified message interaction process, do not existed and transmit time-delay, and increased professional reliability.

Simultaneously, user Ke Da notice also can be sent to the SMC of this user Ke Da notice of application by MSC, and can be owing to reached at the notice that does not have the user, is reverted to can reach the time by unreachable the user, still can't descend short-message sending.

The embodiment of the invention one and embodiment two is with the maximum difference of embodiment three and embodiment four: embodiment three and embodiment four need SMC after HLR or MSC apply for that this user can use the notice that maybe can reach, need obtain the user and can use the SMC that maybe can reach notice just can obtain, continue short-message sending down.But the SMC of embodiment one and embodiment two is receiving after the user can use the notice that maybe can reach, can be initiatively with this notification broadcast to all SMC.Therefore, do not need the application of SMC, simplified flow process, increased the reliability of business realizing.

As seen from the above description, whether the SMC that receives the short message that professional transmit leg submits in the present embodiment no longer inquiry business recipient is the user who belongs to himself, but after the notice that the professional recipient that the SMC that receives professional recipient's ownership broadcasts can use/can reach, directly inquire about the MSC of this user attaching, after the notice that the professional recipient that all SMC that set in advance broadcast can use/can reach, the MSC that belongs to by professional recipient directly issues this short message at the SMC that obtains professional recipient's ownership.That is to say no matter whether professional recipient is the user who belongs to himself, the SMC that receives short message can be responsible for issuing of this short message, and need not carry out short message issuing by the SMC of professional recipient's ownership.Therefore, simplified message interaction process, do not existed and transmit time-delay, and increased professional reliability.

In addition, in the existing short message transmission process, the SMC of professional recipient's ownership will confirm that after following short-message sending success the SMC of professional transmit leg ownership can determine that just short message issuing is successful to the SMC recoil state of professional transmit leg ownership.If for some reason, make the SMC of professional recipient ownership after short-message sending success down, state confirmation is not delivered to the SMC of professional transmit leg ownership, the SMC of then professional transmit leg ownership thinks that short message gives failure, and can not charge.Therefore the wait state acknowledge message has increased the unreliability of business realizing.And the embodiment of the invention with called issue be revised as caller and issue after, do not need wait acknowledge information, therefore increased service reliability.

And, in the existing short message transmission process,, therefore duplicate the problem of charging easily owing to there is forwarding process.For example, after former SMC arrives dilatation SMC with forwards, dilatation SMC generates charging bill after short-message sending success under the professional recipient, and returns the charging acknowledge message to former SMC, after former SMC receives the charging acknowledge message, also will generate a ticket, and former SMC and dilatation SMC all are connected to the same charging center of Home Network, the charging center will be counted expense twice to same user according to two parts of charging bills, therefore damage client's interests, be unfavorable for the development of short message service.To this way to solve the problem is two short message service centers flag bit to be set, and informs the charging center charging way, and for example the ticket with which short message service center charges.But the obvious like this complexity that has increased short message service center and charging center is unfavorable for conventional network equipment is carried out smooth expansion.The embodiment of the invention is generated a ticket and just can be realized chargeing by short-message sending under the SMC of professional transmit leg ownership, has therefore avoided occurring the chaotic problem of chargeing.

Simultaneously, in the existing SMS service distributing scheme, when being the SMC dilatation, dilatation SMC does not play sufficient dilatation effect.When dilatation SMC receives the short message that sends to the user who belongs to former SMC, can be forwarded to former SMC and issue, therefore, the load of former SMC is still higher.For example in the net former SMC is arranged,, set up dilatation SMC, will belong to 50% being assigned to and belonging to dilatation SMC of user of former SMC in order to share the traffic carrying capacity of this SMC 50%.The chance of supposing intercommunication short message between each user is identical, then former SMC is after dilatation, also to receive traffic carrying capacity from dilatation SMC 25%, and to transmit 25% forwarding message to dilatation SMC, so the traffic carrying capacity of actual former SMC and dilatation SMC is 75% of original traffic carrying capacity, and not reaching 50% the traffic carrying capacity that plan is shared, the load at each SMC center is not fully reduced.And the short message that the user who belongs to himself can be sent owing to dilatation SMC in the embodiment of the invention directly be issued to professional recipient, need not transmitted by other SMC, therefore, realize dilatation truly; At last, have only the SMC of following short-message sending successful service transmit leg ownership to generate a ticket, can not produce the chaotic problem of chargeing.

The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.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.
