Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, embodiments of the invention are described in further detail.
When two carrier network intercommunications, the postpaid service user who is signed up in one of them operator can realize the across-network roaming business in the network of two operator's administrations, but because the problem of intelligent network standard butt joint between two, caused the prepaid user can't realize the problem of across-network roaming, cause the prepaid user can't realize the across-network roaming business, therefore only need be when the prepaid user enters other carrier network with self carrier network intercommunication, change its user property into postpaid service user, can provide the across-network roaming business the prepaid user.
In technical scheme provided by the invention, at first definite prepaid user moves to the external network with self place carrier network intercommunication; Changing to the back by the user property with described prepaid user again pays; At last, the network entity in the external network provides the across-network roaming business according to the user property of back paying to described prepaid user.
Fig. 1 is the flow chart of the present invention's first preferred embodiment realization roam cross-network for prepaid users method, and detailed process is as follows:
In step 101, when the prepaid user moves to external network mobile switching centre (MSC), the carrier network intercommunication that this external network MSC and self are signatory, the prepaid user then sends position updating request by self place travelling carriage (MS) to the external network MSC at current place.In the description in this article, abbreviate external network MSC as outer net MSC.
In step 102, after outer net MSC received the position updating request that the MS at current prepaid user place sends, the attaching position register (HLR) of contracting to this prepaid user sent position register request.
The international mobile subscriber identity (IMSI) that in this position register request, carries mobile switching centre's identification number (MSCID) of this outer net MSC at least and be used to identify current prepaid user.Here, MSCID is the unified numbering in the whole world, can unique identification MSC according to MSCID.
In step 103, after HLR receives position register request, determine that according to the IMSI that wherein carries the pairing user of the current position register request of receiving is the prepaid user, determine that according to the MSCID that wherein carries the MSC of this position register request correspondence is the outer MSC of this operator compass of competency again, be outer net MSC, can determine then that current prepaid user moves to outer net MSC this moment; HLR sends roaming to SCP and consults request, wherein carries prepaid user's IMSI and the MSCID of this outer net MSC at least.
Here, HLR also can be undertaken by accounting system and SCP alternately.
In step 104, after SCP receives that request is consulted in the roaming of HLR transmission, account balance and/or the place roaming place MSC current according to current prepaid user, determine whether to allow the across-network roaming business of current prepaid user at this external network, if allow, then in the roaming negotiate response of returning to HLR, carry and allow indication; Otherwise, then in the roaming negotiate response of returning to HLR, carry the refusal indication.
Here, SCP determines whether the prepaid user can roam and can determine according to the roaming control strategy of SCP customization.For example, prepaid user's account balance can the support prepaid user carry out in the roaming place then allowing this prepaid user's across-network roaming business under the situation of caller conversation more than 300 minutes; Perhaps also can whether sign related service with local operator according to place, roaming place operator determines.
In addition, SCP can also determine the business that this prepaid user can use according to current prepaid user's account balance and/or roaming place, place MSC.For example, cancellation user radio business of networking.When SCP had redefined professional that current prepaid user can use, then the business that will redefine was carried at the HLR that sends to this prepaid user place in the roaming negotiate response.In authorizing service lists, the mandate business that the present embodiment suggestion exists can be: voice caller, speech called, Mobile-Originated Short Message, SMS terminal call and calling transfer.
In step 105, HLR receives the roaming negotiate response that SCP returns, what carry in the roaming negotiate response is to allow indication, then this prepaid user's intelligent contactor address list parameter, the constant for example service authorization of the other guide tabulation in the location registers response etc. are carried in HLR cancellation in the current prepaid user's who returns to outer net MSC location registers response.If what carry in the roaming negotiate response is the refusal indication, then HLR is in the current prepaid user's who returns to roaming place MSC location registers response, the customer service grant column list is carried in cancellation, other guide in the location registers response is constant, for example carry intelligent contactor address list parameter etc., make the user can't in roaming network, use MS.In cdma network, the intelligent contactor address list is expressed as the form of Trigger Address List.
Here, HLR makes this prepaid user concerning the MSC of roaming place by this prepaid user's of cancellation intelligent contactor address list parameter, becomes the postpaid service user.
When further carrying professional that the prepaid user that redefines can use in the roaming negotiate response that SCP is returning to HLR, the roaming negotiate response that HLR then returns according to SCP is changed the mandate service lists (Profile) in the register response of position, and returns to outer net MSC by the location registers response.
In step 106, outer net MSC upgrades response by wireless system to current prepaid user's home position according to the location registers response that HLR returns.
Here, do not carry intelligent contactor address list parameter in the location registers response that HLR returns, then expression allows prepaid user's across-network roaming business.Accordingly, when not carrying intelligent contactor address list parameter in the location registers response, then outer net MSC determines that the current location registers of receiving responds corresponding postpaid service user, and then follow-up handling process according to the postpaid service user is handled the miscellaneous service that current prepaid user initiates.Do not have current prepaid user's service authorization tabulation in the location registers response that HLR returns, then expression does not allow prepaid user's across-network roaming business.Accordingly, when not carrying current prepaid user's service authorization tabulation in the location registers response, then MS can't use miscellaneous service in outer net MSC compass of competency.
What more than introduce is to roam into process in the external network with self signatory operator intercommunication as the prepaid user.Below by flow process shown in Figure 2, introduce the prepaid user and return process in self signatory operator compass of competency.In order to simplify description, the operator that the prepaid user is contracted is called local operator, and the network that local operator is administered is called Home Network.Concrete steps shown in Figure 2 are as follows:
In step 201, when the prepaid user returns Home Network, send position updating request to the Home Network MSC at self current place by self employed MS.
In step 202, after Home Network MSC received the position updating request of this MS, the HLR that contracts to current prepaid user sent position register request, wherein carries self MSCID and current prepaid user IMSI at least.
In step 203, HLR is according to the MSCID of IMSI that carries the prepaid user in the position register request and current Home Network MSC, can know that this prepaid user returns Home Network from outer net, then consult request by sending roaming to SCP, this prepaid user of notice SCP returns Home Network from outer net.
In step 204, SCP returns the roaming negotiate response to HLR, and notice HLR returns the prepaid user's attribute that recovers current prepaid user.
In step 205, HLR is to current prepaid user place Home Network MSC home position register response, and the location registers response with respect to returning to outer net MSC in step 105 recovers original intelligent contactor address list parameter.If when this prepaid user roams outer net, when SCP had changed this prepaid user's mandate business, then HLR recovered the original signatory business of this prepaid user at this in the location registers response that this Home Network MSC returns.
At this moment, HLR makes prepaid user's user property revert to pre-payment from the back paying by recover original intelligent contactor address list parameter in the position register response.
In step 206, MS receives the location registers response that Home Network MSC returns, and response is upgraded response to the MS at the current place of prepaid user home position according to location registers.
Fig. 3 comprises MS, MSC, HLR and SCP at least for realizing the system construction drawing of the present invention's first preferred embodiment method.Wherein, MSC is used for when MS moves in self compass of competency, and the attaching position register HLR that the user contracts under this MS sends position register request; And the postpaid service user's attribute that returns according to described HLR indication provides the across-network roaming business to described user.HLR be used for determining according to position register request whether described user is the prepaid user, and whether described user has moved to the external network of the carrier network intercommunication of contracting with described user; When described user for the prepaid user and when moving to described external network, send roaming to described SCP and consult request; And, indicate this prepaid user's user property to pay or pre-payment to described MSC for the back according to the result that described SCP returns.SCP is used for the external network according to described prepaid user and place, and determining whether provides the across-network roaming business to described prepaid user; And return definite result to HLR.
Wherein, HLR determines that according to position register request the prepaid user moves to method that the method for the external network of the carrier network intercommunication of contracting with this user, HLR indicate user property from this prepaid user to MSC pays for the back and the SCP external network according to described prepaid user and place, determine whether to provide the method for across-network roaming business to described prepaid user, can be not described in detail in this referring to the associated description of method in first preferred embodiment.
In addition, when described prepaid user returned the carrier network of self contracting, HLR was reduced to pre-payment with described prepaid user's user property.
Fig. 4 is the flow chart of the present invention's second preferred embodiment method.
In second preferred embodiment of the present invention, by the prepaid user before carrying out across-network roaming, arrive first the management platform place application of the operator that self contracts in advance, the roaming place that self will go to is provided, and the situation that this moment, operator can current prepaid user determines whether to allow user's request.Concrete method can be referring to definite method of step 103～104 in first preferred embodiment.At this moment, when determining that in operator current prepaid user does not satisfy the roaming application that is proposed, can also notify this prepaid user to carry out associative operation, make this prepaid user satisfy the requirement of roaming.Such as, require the user in the pre-paid account of self, to supplement with money etc.When the satisfied roaming of prepaid user required, then operator was provided with across-network roaming information for this prepaid user, has wherein write down the network of prepaid user's permission across-network roaming.
Herein, the method that the user signing contract information of the HLR that current prepaid user contracts is revised by operator can be: the user signing contract information this prepaid user increases across-network roaming information, the business that has wherein write down the roaming place and be authorized to when roaming on this ground.When the prepaid user initiates position updating request in the network of permission across-network roaming, HLR then can be directly according to the record in the roaming information to outer net MSC home position register response, and do not need to hold consultation with SCP again, reduced the number of times of information interaction in the services of roaming.In addition, because the needs of some prepaid user's own service need switch in the network at several operators place, when coming and going between several countries, generally each national operator is all inequality.Therefore, the prepaid user can also apply for the network of more than one country as the permission across-network roaming of self before roaming.
This prepaid user is when carrying out the position renewal, HLR only needs according to the across-network roaming information in active user's CAMEL-Subscription-Information, determine whether the current place of prepaid user external network is recorded, if, then according to the across-network roaming information of correspondence to outer net MSC home position register response; Otherwise, then refuse this position updating request, promptly this prepaid user can't realize the across-network roaming business.
The concrete steps of flow process shown in Figure 4 are as follows:
In step 401～402, concrete step is identical with step 101～102 in first preferred embodiment, is not described in detail in this.
In step 403, HLR receives the position register request that outer net MSC sends, HLR is in the across-network roaming information of current prepaid user's CAMEL-Subscription-Information, whether the network of searching this outer net MSC place is the network that allows across-network roaming, if not, HLR then in the location registers response of returning to outer net MSC, cancels current prepaid user's basic service mandate; If, HLR then according to the record in the across-network roaming information to outer net MSC home position register response, comprise the intelligent contactor address list parameter that this prepaid user is not carried in the basic service mandate.
In step 404, roaming place MSC upgrades response according to the location registers response that HLR returns to current prepaid user's home position.
Here, do not carry intelligent contactor address list parameter in the location registers response that HLR returns, then expression allows prepaid user's across-network roaming business.Accordingly, when not carrying intelligent contactor address list parameter in the location registers response, then outer net MSC determines that current location registers response of receiving corresponds to the postpaid service user, and then follow-up handling process according to the postpaid service user is handled the miscellaneous service that current prepaid user initiates.Do not have current prepaid user's service authorization tabulation in the location registers response that HLR returns, then expression does not allow prepaid user's across-network roaming business.Accordingly, when not carrying current prepaid user's service authorization tabulation in the location registers response, then MS can't use miscellaneous service in outer net MSC compass of competency.
Fig. 5 is for returning the process in self signatory operator compass of competency corresponding to the prepaid user of the present invention's second preferred embodiment.Be specially:
In step 501～502, in embodiment and first preferred embodiment identical in step 201～202, be not described in detail in this.
In step 503, HLR is according to the MSCID of the IMSI that carries the prepaid user in the position register request and self place MSC, can know that this prepaid user returns Home Network from outer net, then in the location registers response of returning, recover prepaid user's attribute of current prepaid user, promptly recover original intelligent contactor address list parameter; And when this prepaid user's the professional change of mandate, then HLR recovers the original signatory business of this prepaid user at this in the location registers response that this Home Network MSC returns.
At this moment, HLR makes prepaid user's user property revert to pre-payment from the back paying by recover original intelligent contactor address list parameter in the position register response.
In step 504, MS receives the location registers response that Home Network MSC returns, and response is upgraded response to the MS at the current place of prepaid user home position according to location registers.
Fig. 6 realizes the system construction drawing of the second preferred embodiment method for the present invention, and this system comprises: MS, MSC and HLR.Wherein, MSC is used for when mobile station MS moves in self compass of competency, and the HLR that the user contracts under this MS sends position register request; And provide the across-network roaming business to described user according to the indication of postpaid service user's attribute of HLR.HLR is used for determining according to position register request whether described user is prepaid user and the external network that moves to the carrier network intercommunication of contracting with this user; When definite described user for the prepaid user and when moving to described external network, HLR then indicates this user's user property to pay for the back to current this user place MSC.Here, HLR can also be further determines whether that according to described prepaid user's user signing contract information indication changes its user property into back and pays, and concrete grammar is not described in detail in this as described in the step 403 in second preferred embodiment.
In addition, HLR determines that according to position register request the prepaid user moves to the method for the external network of the carrier network intercommunication of contracting with this user, HLR and indicates the method for this prepaid user's user property for the back paying to MSC, can be not described in detail in this referring to the associated description of method in second preferred embodiment.
In addition, when described prepaid user returned the carrier network of self contracting, HLR was reduced to pre-payment with described prepaid user's user property.
When the prepaid user adopts the user property of back paying to enjoy the across-network roaming business, the prepaid user is carried out postpaid service user's charging way, when periodically settling accounts, SCP deducts from this prepaid user's account again.
In the across-network roaming business, because the prepaid user is adopted the strategy of first use, back charging, so can suitably control the business that the prepaid user uses, to avoid prepaid user's malicious overdraft.For example when the prepaid user uses the beginning to exhale business, set in advance and begin to exhale controlled condition; And return to by HLR and carry the beginning in the location registers response message of this external network MSC and exhale the trigger parameter, the beginning is set exhale trigger on this external network MSC.When this prepaid user initiates to begin to exhale business, this external network MSC triggers the beginning and exhales trigger, sends to HLR and begins to call for to ask (ORREQ) message, and this HLR is according to judging whether the business of exhaling of current beginning satisfies the beginning and exhale controlled condition, if then indicate described external network MSC to remove this calling; Otherwise, then indicate described external network MSC to continue to continue, finish subsequent operation.
It can be by HLR white list strategy or blacklist to be set that the beginning is here exhaled controlled condition.In white list, be provided with and allow number section dialed, have only the current number of dialing of prepaid user in white list, then allow continuing of this calling; Otherwise, remove this calling.In blacklist, be provided with and do not allow number section dialed, as long as the current number of dialing of prepaid user in blacklist, is then removed this calling; Otherwise, allow continuing of this calling.
Method black, white list specifically is set can be provided with according to concrete country.For example, only allow the prepaid user of across-network roaming to dial the number of certain several country, then can in white list, increase the international number prefix and the national code of these several countries; And for example, when the prepaid user of restriction across-network roaming dials the number of certain several country, then can in blacklist, increase the international number prefix and the national code of these several countries.
The method and system of realization roam cross-network for prepaid users provided by the present invention can be widely used in mobile communication system such as CDMA, GSM.Simultaneously, because each state is all in the compass of competency of native country operator, therefore method and system provided by the invention also can well be applied to international roaming service.In addition, mainly be owing to the butt joint problem between the intelligent network between the operator because the prepaid user can't realize the across-network roaming business, therefore present research focus concentrates on the problem that how to solve the intelligent network butt joint.And the present invention is by changing thinking, changes prepaid user's user property into back and pays, and realized prepaid user's across-network roaming business, and reduced the complexity and the technical difficulty of system.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
