Abstract
The method includes such steps as (a) when as calling party launches a calling, roaming intelligent user sends operation code of unstructured supplementary service data (USSD) and request of USSD of called user's number to attributive service control point (SCP); (b) after receiving USSD request, SCP determines whether operation code of USSD is a service of UCB returned from USSD and whether the calling user is allowed for using UCB service; if yes, entering into (c); otherwise, ending the flow; (c) attributive SCP of calling user orders relevant SSP to build call jointing from SSP to calling party and SSP to called party respectively, and determines whether building a call is successful; if yes, SSP builds voice channel between calling party and called party, realizing communication; otherwise this flow is ended.
Description
Technical field
The present invention relates to the roaming call technology of intelligent subscriber, can't realize the method that a kind of intelligent subscriber under the mutual situation makes a call between visit ground and the ownership place intelligent network when being meant intelligent user roam especially.
Background technology
At present, in the operation of mobile radio communications such as global mobile communication (GSM) system and code division multiple access (CDMA) system, the quantity of intelligent subscriber proportion in the mobile subscriber increases year by year, and said here intelligent subscriber includes but not limited to use the user of prepayment service, the user of use Mobile Virtual Private Network Service.So, along with the increase of intelligent subscriber ratio,, intelligent subscriber just becomes more and more outstanding for providing the requirement of particularly international roaming function of roaming function.For each intelligent subscriber, its user profile leaves on the Service Switching Point (SCP) of ownership intelligent network, when this intelligent subscriber roams, especially during international roaming, in the prior art, roam the intelligent network of on-site network and belonging area network or be not connected or can't be mutual, so how the ownership SCP that user's calling is triggered to this intelligent subscriber has just become a key issue.That is to say that because technical reason, operator can't provide some services of roaming for intelligent subscriber.
Mobile intelligent network service, the basic characteristics that include but not limited to prepayment service, Mobile Virtual Private Network Service are: when intelligent subscriber attempts to make a call or answers the call, core net need be reported the information of this calling to the intelligent equipment under the current intelligent subscriber, by the information of mobile intelligent net system according to the user, as: information such as user's account balance, the term of validity, determine whether allowing core net this calling that continues, thereby reach the control customer call, realize the purpose of chargeing.As seen, realize that by Intellight network mode IN service has two basic demands:
1) whether be intelligent subscriber to equipment of the core network if can discern a calling both sides in the calling;
2) equipment of the core network can be reported the situation of this calling and accept the control of intelligent network to intelligent network.
Because mobile intelligent net has its special characteristics, under present technical conditions, provide services of roaming to intelligent subscriber if desired, then need the visit ground operator of the home-operator of intelligent subscriber ownership place and current roaming to adopt identical mobile intelligent net system, identical IN service scheme and flow process, the network between two operators is wanted and can be interconnected simultaneously.But, in existing mobile intelligent net international norm and the agreement not scheme, the signaling process to IN service make clear and definite regulation, therefore, want between the different intelligent movable network operation business of country variant even different regions, to realize the roaming of intelligent subscriber, have suitable difficulty.Problem below concrete the existence:
1) for an IN service, mainly comprise two flow processs: one is the control flow that the user is made a call, and another is the control flow to user's call accepted.When the user roams, during as international roaming, in the mobile network, owing to have only user's home network can obtain user's roaming position, so the user does regardless of calling subscriber's position, to call out the home network that will be routed to the user when called.Therefore, for an intelligent subscriber, when its roaming is done when called, owing to call out the home network that will be routed the reuse family, and home network itself has been built intelligent network, and so existing technology is to realize that fully called situation is made in user's roaming to be monitored.
But when caller is done in user's roaming, whole calling procedure will not need to be related with user's home network.For the user attaching network, whether the unique decision exactly that can make gives to do when the user roams the authority of caller, if give user right, ability according to existing network, unless the intelligent network of the core net of user's roaming network and user attaching network has been set up according to certain intelligent network standard and has been connected, otherwise can't further limit the user, the network of user's roaming simultaneously also can't limit the user, also is like this to intelligent subscriber.Like this, just can't guarantee user's calling is realized control and charging.
2) the mobile intelligent net system in the current practical application, there is the customization that strengthens logic based on the mobile network to use (CAMEL) standard, also have based on intelligent network application protocol (INAP) standard, these are impossible based on the intercommunication that will realize IN service between the intelligent network of different systems substantially.
3) for based on the intelligent network under the same system, problem owing to a series of realizations such as the signaling process of in intelligent network protocol, not stipulating IN service, business norms, therefore there are its special pre-payment signaling specification and business norms the operation commercial city of country variant, or network equipment supplier provides special pre-payment signaling specification and business norms for it.Two operators will realize the intercommunication of IN service, the intelligent user roam of a country time still can make a call to another one country, according to traditional approach, the intelligent network of a country of requirement wants to control the equipment of the core network of another national operator, and this just needs the pre-payment signaling specification and the business norms of these two operators identical.But in fact, these pre-payment signaling specifications and the business norms of different operators often have nothing in common with each other, and pre-payment signaling specification that different network equipment suppliers provides and business norms are often also inequality.Therefore, realize in the country that intelligent subscriber can roam into outside this state and makes a call, this intelligent subscriber of inevitable requirement belongs to the home-operator of state and the network of visit ground operator changes, and makes both pre-payment signaling specification and business norms complete unities.This must affect greatly the existing network of this operator, and the existing network business is caused greater impact, has increased the risk and cost that carrier network is safeguarded greatly.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method that makes a call when realizing intelligent user roam, intelligent subscriber can be made a call as caller when roaming, and then make operator provide the more business of horn of plenty to the user.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of method that makes a call when realizing intelligent user roam, this method may further comprise the steps:
When a. Man You intelligent subscriber makes a call as caller, send the USSD request that contains unstructured supplementary service data (USSD) service code and called number to the home service control point (SCP) of self;
B. whether corresponding USSD callback (UCB) is professional and allow the calling subscriber who makes a call to use the UCB service to judge USSD service code in the request, if, then enter step c, otherwise, this call flow finished;
C. calling subscriber's ownership SCP order self corresponding service exchange point (SSP) is set up SSP respectively to the calling subscriber with arrive called subscriber's call proceeding;
D. judge whether successfully to set up SSP to the calling subscriber with to called subscriber's calling,, realize the conversation between calling and called if the speech channel between calling subscriber and the called subscriber is set up in then two and half sections callings of SSP bridge joint; Otherwise, finish this call flow.
Wherein, described SSP to the calling subscriber with to called subscriber's calling is: set up the call proceeding of SSP earlier to the calling subscriber, set up successfully after, set up the call proceeding of SSP again to the called subscriber.After SSP set up successfully to calling subscriber's call proceeding, SSP can be to calling subscriber's broadcast just at the prompt tone of continuing called subscriber.
Described step b further comprises:
B1. the USSD request that the calling subscriber sends among the step a is sent to the affiliated attaching position register (HLR) of calling subscriber through the mobile switching centre (MSC) at the current place of calling subscriber;
B2. calling subscriber's ownership HLR directly is transmitted to this USSD request calling subscriber's ownership SCP;
B3. after calling subscriber's ownership SCP receives this USSD request, analyze calling number and called number earlier, judge then whether the USSD service code in the USSD request is the UCB business, if not, this call flow then finished; Otherwise, further to calling subscriber's authentication, judge whether to allow this calling subscriber to use the UCB service, if allow, then enter step c, if do not allow, then finish this call flow.
The described SSP of foundation further comprises to caller or to called subscriber's calling:
C1.SSP sends out the message SendRoutingInfo that sends routing information to caller or called subscriber's ownership HLR;
C2. by caller or called subscriber's ownership HLR this caller or called subscriber's roaming number is returned to SSP;
C3.SSP sends the initial address message (IAM) that carries this user's roaming number according to this caller or called subscriber's roaming number to the MSC at caller or the current place of called subscriber;
C4. judge whether to receive address-complete signal (ACM) message and answer signal (ANM) message that the MSC at caller or the current place of called subscriber returns, if have, then call setup success, SSP reports caller or called subscriber's the incident of replying to calling subscriber's ownership SCP; Otherwise call setup is unsuccessful.
This method further comprises: the calling and called user's communication finishes, after SSP detected onhook event, SSP was respectively to calling subscriber and called subscriber's ownership SCP report of user onhook event, receive the call release order that SCP issues after, the SSP dismantling call discharges shared resource.
Be divided into three kinds of situations for on-hook: the on-hook of caller elder generation, called first on-hook, calling and called on-hook simultaneously.Processing procedure is respectively so:
After SSP detected the on-hook of calling subscriber elder generation, this method further comprises: SSP reported calling subscriber's onhook event to calling subscriber's ownership SCP, and the SCP of calling subscriber's ownership sends the call release order to SSP; SSP reports calling subscriber's onhook event to the SCP of called subscriber's ownership, and the SCP of called subscriber's ownership is to the order of SSP transmission call release, and SSP removes the calling of called subscriber's side, and discharges shared resource.
After SSP detected the on-hook of called subscriber elder generation, this method further comprises: SSP reported called subscriber's onhook event to the SCP of called subscriber's ownership, and the SCP of called subscriber's ownership sends the order of call release to SSP; SSP reports called subscriber's onhook event to the SCP of calling subscriber's ownership, and the SCP of calling subscriber's ownership is to the order of SSP transmission call release, and SSP removes the calling of calling subscriber's side, and discharges shared resource.
When SSP detects calling subscriber and called subscriber's on-hook simultaneously, this method further comprises: SSP reports calling subscriber or called subscriber's onhook event to the SCP of calling subscriber's ownership, SCP to called subscriber's ownership reports calling subscriber or called subscriber's onhook event simultaneously, the SCP of the SCP of calling subscriber's ownership and called subscriber's ownership sends the order of call release respectively to SSP, SSP discharges shared resource after receiving the call release order.
After the calling and called user's communication finishes, this method further comprises: SSP by calling subscriber and called subscriber's response time separately as the charging starting point, report chargeable time information to the SCP of calling subscriber's ownership and the SCP of called subscriber's ownership respectively, the SCP of the SCP of calling subscriber's ownership and called subscriber's ownership charges to calling subscriber and called subscriber respectively.Or, SSP with time of bridge joint success as the charging starting point, report chargeable time information to the SCP of calling subscriber's ownership and the SCP of called subscriber's ownership, the SCP of the SCP of calling subscriber's ownership and called subscriber's ownership charges to calling subscriber and called subscriber respectively.Or SSP reports chargeable time information with time of bridge joint success charging starting point as the calling subscriber to the SCP of calling subscriber's ownership, and the SCP of calling subscriber's ownership charges to the calling subscriber; Simultaneously SSP reports chargeable time information with called subscriber's the response time charging starting point as the called subscriber to the SCP of called subscriber's ownership, and the SCP of called subscriber's ownership charges to the called subscriber.
In the such scheme, described called subscriber is intelligent subscriber or common global system for mobile communications (GSM) user or fixed network user or PBX (PBX) user or code division multiple access system (CDMA) user.
Therefore, the method that makes a call during realization intelligent user roam provided by the present invention, be when intelligent user roam makes a call as caller, ask by sending out unstructured supplementary service data (USSD) by this intelligent dialing user, thereby the calling that intelligent subscriber initiates is triggered on the SCP of this intelligent subscriber ownership to the Service Control Point that self belongs to.The present invention only requires that the mobile switching centre (MSC) of roaming place mobile communications network supports the USSD function to get final product, reduced coherence request, thereby solved the problem that intelligent subscriber makes a call when international or some regional roaming intelligent network between roaming location and the ownership place.
When can effectively providing the intelligent subscriber world or zone roaming for operator, such scheme makes the solution of caller, help operator to provide the more business of horn of plenty to the end user, increase the operation income of operator, for the user provides better service, also provide a great convenience simultaneously for the transnational or trans-regional communication of end user.
In addition, be the standard signaling because USSD request adopts, and general MSC support the USSD function, so the present invention implements simply, make things convenient for, and applied widely.

Embodiment
Because the user profile of intelligent network user all is stored on the SCP, the present invention solves the calling of how intelligent subscriber being initiated in the strange land to be triggered on the SCP of this intelligent subscriber ownership.Again because general MSC supports the USSD function, adopt USSD signaling transmitting control message to have versatility, based on this, realization thought of the present invention is exactly: when the intelligent subscriber of roaming makes a call as caller, this intelligent subscriber is by sending a USSD request, belong to SCP control by this intelligent subscriber and set up call proceeding, set up Service Switching Point respectively to the calling between this intelligent subscriber and the called subscriber, then after SSP sets up success to the calling between this intelligent subscriber and the called subscriber, by half section calling of two ons of SSP bridge joint, realize the conversation between the calling and called at last.
Set up earlier among the present invention SSP to caller and called between path, return to connect caller and called this process again after all setting up successfully calling out, can be referred to as the USSD call-back service.Fig. 1 be the present invention based on UCB call out networking diagram, as shown in Figure 1, user A represents that one roams into another state or another regional intelligent subscriber, be the intelligent subscriber that makes a call by USSD, MSC/VLRa belongs to the visited network of intelligent dialing user A, and SCPa and HLRa belong to the home network of intelligent dialing user A; Intelligent subscriber B is the user of call accepted, and MSC/VLRb belongs to the visited network of called intelligent subscriber B, and SCPb and HLRb belong to the home network of called intelligent subscriber B; Service Switching Point/gateway MSC (SSP/GMSC) belongs to the home network of intelligent subscriber A, directly inserts the SCPa of intelligent subscriber A ownership.
When user A makes a call, send out a USSD and ask to HLRa/USSD, HLRa is transmitted to SCPa with this USSD request again, and mutual by between SCPa, SCPb and the SSP/GMSC set up the speech channel between user A and the user B then.Phase I among the figure represents to set up the calling of SSP to user A, and second stage represents to set up the calling of SSP to user B, and the stage refers to the reciprocal process between SSP and the SCPa.
When carrying out international roaming with intelligent subscriber A between two countries below, calling intelligent user B is an example, and the present invention is further detailed explanation in conjunction with the accompanying drawings simultaneously.
Networking structure figure based on shown in Figure 1 Figure 2 shows that the call flow diagram based on UCB, and the signaling among the figure shown in the dotted line is MAP (MAP) signaling, and the signaling shown in the solid line is CAMEL Application Part (CAP) signaling.The concrete calling procedure of present embodiment may further comprise the steps:
Step 1: when intelligent subscriber A wishes to make a call, this intelligent subscriber A initiates request by a USSD request to ownership SCPa, wherein, contain USSD service code and called number in this USSD request, the USSD service code here should be the professional corresponding service sign indicating number of UCB.
Step 2: USSD request the passing through signaling network of intelligent subscriber A, that is: the visited MSC a of process intelligent subscriber A is sent to the ownership HLRa of intelligent subscriber A, because visited MSC is supported the USSD function, so support the transmission of USSD request, ownership HLRa is forwarded to the USSD request ownership SCPa of intelligent subscriber A.
Step 3:SCPa asks according to the USSD of intelligent subscriber A earlier, analyze calling number and called number, judge whether whether the service code in the USSD request is the UCB business, if, SCPa carries out authentication to intelligent subscriber A again, if permission intelligent subscriber A enjoys the UCB service, then SCPa order SSP begins to set up calling; If do not allow intelligent subscriber A to enjoy the UCB service, return failure information to intelligent subscriber A, finish this call flow.
Step 4:SSP receive from SCPa set up call command after, set up self calling to intelligent subscriber A: SSP process and SCPa's is a series of mutual, issue charge order and indicating call by SCPa and proceed, SSP HLRa under intelligent subscriber A sends the message SendRoutingInfo that sends routing information; Afterwards, by HLRa under the intelligent subscriber A this user's roaming number MSRN is returned to SSP, SSP continues according to the roaming number MSRN of intelligent subscriber A, sends the visited MSC that the initial address message (IAM) that carries intelligent subscriber A roaming number MSRN arrives the current place of intelligent subscriber A that is:.
If the call setup success, then SSP can receive address-complete signal (ACM) message and answer signal (ANM) message that the visited MSC at the current place of intelligent subscriber A is sent back to, so, and the incident that SSP just reports intelligent subscriber A to reply to SCPa; After SCPa received that intelligent subscriber A that SSP reports replys incident, order SSP connected intelligent subscriber A.If call setup is unsuccessful, SSP then reports the call setup failure information to SCPa, and finishes this call flow.
After step 5:SSP connects intelligent subscriber A, can be to intelligent subscriber A playing alert tones, prompting is called out and is continued, and please wait for, simultaneously to SCPa report on intelligent subscriber A; After SCPa received report, order SSP began intelligent subscriber B is continued.Here, SSP also can be to intelligent subscriber A playing alert tones, and intelligent subscriber A just is in mute state and waits for connection intelligent subscriber B.
Step 6: because need the party B-subscriber be chargeed, so the ownership SCPb of SSP elder generation and intelligent subscriber B carries out alternately by the ownership SCPb of intelligent subscriber B; The ownership SCPb of intelligent subscriber B issues the order of chargeing, and indicating call is proceeded.
After step 7:SSP receives order from SCPb, set up self calling: SSP and send the message SendRoutingInfo that sends routing information to the HLRb at intelligent subscriber B place to intelligent subscriber B, and HLRb fetches the roaming number MSRN of intelligent subscriber B under the intelligent subscriber B, roaming number MSRN according to intelligent subscriber B continues then, sends the MSC of end office (EO) that the IAM message that carries intelligent subscriber B roaming number MSRN arrives intelligent subscriber B place that is:.
If the call setup success, then SSP can receive address-complete signal (ACM) message and answer signal (ANM) message that the intelligent subscriber B place MSC of end office (EO) sends back to, so, and the incident that SSP just reports intelligent subscriber B to reply to SCPa; After SCPa receives the incident that party B-subscriber that SSP reports replys, two and half sections callings of order SSP bridge joint.
Two and half sections callings of step 8:SSP bridge joint, the speech channel between intelligent subscriber A and the intelligent subscriber B is connected, and can begin conversation.
Step 9: end of conversation between intelligent subscriber A and the intelligent subscriber B, the on-hook of intelligent subscriber A elder generation, then SSP reports chargeable time information and intelligent subscriber A onhook event to SCPa, also reports chargeable time information and intelligent subscriber A onhook event to SCPb simultaneously.
Step 10:SCPa and SCPb charge to calling subscriber and called subscriber respectively, and order SSP dismantling call; SSP removes the calling of intelligent subscriber B side, the terminated call process, and discharge shared resource.
Above-mentioned steps only is all intelligent subscriber to A, B, and the situation of intelligent subscriber A elder generation on-hook is described, and is common GSM user or fixed network user or PBX user or CDMA user for user B; And the situation of on-hook of user B elder generation or user A, B on-hook simultaneously can adopt and the similar process of this flow process equally, and local side that only relates to or dismantling call are not exclusively the same with the step of release resource.
For instance, after SSP detected the on-hook of called subscriber elder generation, SSP reported called subscriber's onhook event to the SCP of called subscriber's ownership, and the SCP of called subscriber's ownership sends the order of call release to SSP; SSP reports called subscriber's onhook event to the SCP of calling subscriber's ownership, and the SCP of calling subscriber's ownership is to the order of SSP transmission call release, and SSP removes the calling of calling subscriber's side, and discharges shared resource.Equally, when SSP detects calling subscriber and called subscriber's on-hook simultaneously, SSP reports calling subscriber or called subscriber's onhook event to the SCP of calling subscriber's ownership, SCP to called subscriber's ownership reports calling subscriber or called subscriber's onhook event simultaneously, the SCP of the SCP of calling subscriber's ownership and called subscriber's ownership sends the order of call release respectively to SSP, SSP discharges shared resource after receiving the call release order.
In addition, above-mentioned steps is at general call setup order, is established to the calling of intelligent subscriber A earlier that is:, is established to the calling of user B again.But, because intelligent subscriber A international roaming or zone roaming, the calling that SSP is established to intelligent subscriber A is actually an international long-distance or regional long-distance, from the charging angle, though the calling to user B also there is not foundation, but the roaming place of user A has begun to have calculated the international long-distance expense of user A, and so the home-operator of user A will be born certain loss.Therefore, because known called number also can be set up the calling of SSP to user B earlier, be established to the calling of intelligent subscriber A again.This kind situation only needs user B to wait for a period of time after replying and converses, can reduce the loss of operator relatively.As for the calling of setting up SSP and which user earlier, can adopt different call setup orders according to the requirement of calling subscriber's ownership place operator by the SCP decision of calling subscriber's ownership.
After the UCB call treatment finishes, need correctly charge for the user, that is to say, after the step 1 of said process～step 10 is finished, SCPa and SCPb just obtain the correlometer charge information that SSP reports, as information such as the duration of calls, determine from when beginning then to determine that the starting point of charging has two kinds of possibilities by SSP as the charging starting point:
1) time according to user answer begins to charge: intelligent subscriber A and user B are begun to charge according to the time of replying separately respectively.
2) time according to the success of SSP bridge joint begins to charge: intelligent subscriber A was begun to charge according to the time of SSP bridge joint success, to user B, if user B is intelligent subscriber, then user B is also begun to charge according to the time of SSP bridge joint success; If user B is non intelligent user, then user B is still begun to charge by its response time.
Intelligent subscriber made the problem of caller when the present invention not only can realize international roaming, in same country, intelligent subscriber visit with the ownership place intelligent network can not intercommunication situation suitable equally.And, the concrete signaling process of the present invention also has other arrangement, compound mode, these concrete arrangements, compound mode may be with different shown in the signaling process figure in the foregoing description, but are the same goal of the invention that adopts technical solution of the present invention to realize equally.Such as, include but not limited to: in the step 4,5,6 SCPa order SSP be established in calling subscriber's the calling procedure and afterwards SSP and SCP may have different combinations and realization alternately; In the step 7 SCPa order SSP be established in called subscriber's the calling procedure and afterwards SSP and SCPa may have different combinations and realization alternately.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
