Abstract

The present invention provides a method for realizing notification service in roaming state. The present invention comprises the following steps: a. a user sends location updating application to the MSC/VLR (Mobile Service Switching Center/VisitorLocation Register), and the MSC/VLR (Mobile Service Switching Center/VisitorLocation Register) sends location updating application to the HLR of the user; b. the HLR receives the information of the location updating application, and judges that if the user is in roam or not; c. the HLR decides if send short messages according to the roam judging result. The present invention realizes the notification service for a user in roaming state by adding the capacity of sending short messages and the processing logic of judging the roaming property when the user is out of a district (country) to the HLR, can avoid the telephone traffic disputes caused by the accidental roaming out of the district (country), increases the user's satisfaction degree, and reduces the operator's operating cost.

Description

A kind of method that realizes the roaming state informing business
Technical field
The present invention relates to the mobile communication technology field, relate to a kind of specifically by HLR (Home Location Register: the method for realization roaming state informing business Home Location Register).
Background technology
Along with the continuous development of mechanics of communication, mobile communication has obtained using widely, and the user travels outside and often carries mobile phone so that get in touch with client, kith and kin.As user during in the intersection of same standard heterogeneous networks or intersection roaming, often because the telephone expenses dispute is caused in the base station that mobile phone signal " mistake " is linked in the bipartite network (or regional) in the consolidated network different regions.Such as think be intra area in fact but cause interzone call because mobile phone is linked into the base station in other area; Think it is the international call that is actually of domestic call, especially in the area that has a common boundary with Hongkong and Macro, this problem is even more serious.
Because it is that power according to signal is carried out automatically fully that mobile phone switches between different base station, the user is to own current institute access network and unclear, even and be in the same localities, also can cause mobile phone to be linked in the different networks because of the variation of peripheral base station signal, produce a large amount of traffic disputes thus, all bring very big trouble for mobile subscriber and operator.
At this type of phenomenon, prior art solutions has two kinds: random zone method for limiting and ticket special treatment method.Introduce this two kinds of prior aries below respectively:
First method, the random zone method for limiting is exactly that random zone by limited subscriber prevents trans-regional roaming, such as in order to prevent user's trans-regional roaming, just the authority with the user is restricted to local roaming, it is to allow local MSCID (Mobile Switching CentreIdentity) the mobile switching centre's User Identity or VLRID (Visitor LocationRegister Identity) the Visited Location Registor User Identity of user's roaming to be registered among the HLR, when the user carries out the position renewal at every turn, HLR just mates permission roaming MSCID (perhaps VLRID) tabulation of user's present located MSCID (perhaps VLRID) and registration, if the former is included among the latter, then allow the position updating request success, otherwise refused.Like this, when the user roamed out the frontier district, the user was because can not carry out the position upgrades, thus just can not caller, called, thus stop unexpected inter-zone call charging dissension.According to identical reason,, also can stop unexpected transnational call charging dispute by the limited subscriber roaming of going abroad.
Second method, the ticket special treatment method is exactly after unexpected inter-zone call of user or transnational calling, ticket is still according to normal mode output, but the operator in two nets or two areas holds consultation at this part telephone expenses, in clearing this part telephone expenses is done special processing.
There are many deficiencies in obvious above-mentioned prior art, particularly is meant:
The control mode of first method is dumb.In order to prevent the telephone expenses dispute, system has directly limited user's roaming authority, and this method is fine to the low end subscriber of a part, but because random zone is imposed restrictions on, most domestic consumer is difficult to accept; In addition, the restriction roaming also can cause the operator a large amount of long-distance call telephone expenses of loss indirectly, unless forced, operator can not accepted this method yet.
Second method is loaded down with trivial details, performance difficulty, and accuracy is very low.Because the ticket on the MSC produces by ordinary call, in accounting system clearing telephone expenses, must handle one by one ticket according to user's complaint or historical deal with data, the management cost that drops into is very high, accuracy is very low, inevitably produce very big error, and may owing to normal inter-zone call according to accident transregional (state) call treatment, can cause a large amount of telephone expenses of operator to run off; In addition, this method is kept away unavoidable complaint, because the processing of ticket user's complaint and then processing earlier often, so even operator satisfies the requirement of complaining the user to sacrifice telephone expenses, but frequent complaint also can reduce the brand image of operator.
Summary of the invention
At said circumstances, the present invention proposes a kind of method that realizes the roaming state informing business, it, is avoided owing to the user does not know the problems such as telephone expenses dispute that the present located service network causes with the current roaming state of short message way fast notification user by HLR.
For achieving the above object, the present invention proposes a kind of method that realizes the roaming state informing business, increase the module of differentiating user roaming state and the processing module that sends SMS message on HLR, this method comprises following steps:
A. the user (Mobile Service Switching Center/Visitor LocationRegister: mobile services switching centre/Visited Location Registor) initiate position updating request, this MSC/VLR initiates position updating request to user attaching HLR to MSC/VLR;
B.HLR receives this location update request message, judges whether this user roaming has taken place;
Whether decision sends the short message that comprises the current roaming state information to c.HLR according to the roaming judged result.
Increase signatory administration module again on HLR, be used for the signatory management to the user roaming state informing business, described step b more specifically may further comprise the steps:
B1.HLR receives this location update request message;
B2.HLR judges whether this user roaming has taken place; If continue so, otherwise carry out the common standard flow process;
Whether b3.HLR judges called signatory and activated the roaming state informing business, if carry out next step so, otherwise carry out the common standard flow process.
Judge whether this user roaming has been taken place specifically be meant:, judge whether this user roaming has taken place by the User Identity MSCID of mobile switching centre, the Visited Location Registor User Identity VLRID that report in the comparison position update inquiry information and the MSCID/VLRID that preserved last time.
Described step c further comprises:
If c1. user's roaming, the HLR structure comprises the short message of roaming state information, and this short message is sent to the MC of short message service center;
C2.MC sends to the user with this short message.
Comprise further also among the described step c2 that MC returns the notice of correct this short message of reception to HLR.
The method of described realization roaming state informing business is by increasing the signatory management function module of roaming state informing business, the processing module that sends SMS message on described HLR, differentiating roaming character and realize according to differentiating the function logic processing module that the result sends SMS message.
The present invention realizes the user roaming state notice by increasing the ability that sends SMS message and increase the processing logic of differentiating user transregional (state) roaming character on HLR, can avoid owing to accident is roamed out the traffic dispute that district (state) causes, improve user's satisfaction, reduce the operation cost of operator.Particularly, it has following advantage:
1. can fundamentally solve telephone expenses dispute problem.Learn the roaming state of oneself as the user after, just can according to circumstances determine whether continuing caller, called service.Like this, do not changing the ticket producing method of MSC, do not changing the present situation of tent center charging way, operator just can be carried out telephone expenses to the call business of this class according to normal process and be collected.No matter being operator or user, all is acceptable to this processing mode.
2. the roaming state notice quick and precisely.In view of HLR is first network entity of accurately knowing user of current roaming position information, so the present invention can be notified to the user with user's roaming state (roaming in the district, National roaming, international roaming) in the very first time, real-time is relatively good.
3. exploitativeness is good.Only need do simple upgrading to existing network HLR, promptly on the basis of existing network HLR, increase can be finished this function to the parameter registration and the business processing logic of roaming state informing business, need not other network entity is done any change, and scheme is simple, the cycle is short, risk is little.

Specific implementation
The described method that realizes the roaming state informing business by HLR of the embodiment of the invention, it is applied to present widely used CDMA (Code Division Multiple Addressing: network code division multiple access), the mobile base station), the MSC2/VLR2 of MC, the user A ownership of MSC1/VLR1, the HLR on visit ground, user A ownership in the service area in this network, comprising: the MS on user A, this user A visit ground (Mobile Station:.
Before describing the described method of the embodiment of the invention, at first carry out three following work by HLR realization roaming state informing business.
1, on above-mentioned existing network HLR, increases the storage to roaming state informing business functional parameter, signatory management function.
Other benchmark services of supporting with HLR are identical, and the functional parameter of this roaming state informing business comprises: contract/remove signatory state, activation state.This traffic performance has only the user signatory and activated under this professional situation and just come into force.
According to the management practice of mobile service attribute, contracting and going of user roaming state informing business contracted because may relate to charging, generally can only safeguard by the business hall; The activation of traffic performance requires both can be undertaken by business hall (perhaps service hotline), also can be by the mobile phone operation sign indicating number of standard, and the standard FEATURE of utilization operates, to make things convenient for the flexible use of traffic performance.
2, increase the processing module that sends SMS message at existing network HLR.
This module supports short message to send instruction (SMSDeliveryPointToPoint) and the MC execution result instruction (SMSDeliveryPointToPointReturnResult) at this message feedback, the detail parameters in these two instruction flows and the instruction can referring in the CDMATIA/EIA-41D standard agreement to the agreement of short message handling process.
Owing in HLR, increase the identical of short message handling process, do not repeat them here with other standard agreement message flow of increase.
3, the operation flow of change HLR position renewal increases the differentiation of roaming character and the function logic that sends SMS message according to judged result.
Processing logic when to the effect that transforming HLR to user position update, promptly after receiving REGREQ message, handle according to following service logic according to the roaming state informing business processing capacity parameter of the MSCID/VLRID of the current location that comprises in the message, the previous position renewal MSCID/VLRID that in database, keeps and user's registration.
IF (the roaming character of MSC1 and MSC2 (in this area, domestic, the world) is different, and user A is signatory and activated the roaming state informing business)
{
IF (user roams in the area outside the area)
{
Content of short message is set is " roaming into the other places ";
}
ELSE IF (user roams into this locality from the other places)
{
Content of short message is set is " roaming into this locality ";
}
ELSE IF (user goes abroad from National roaming)
{
Content of short message is set is " roaming into external ";
}
ELSE IF (user is domestic from abroad roaming into)
{
Content of short message is set is " roaming into domestic ";
}
Content of short message required coding according to standard agreement and be kept in the SMS_BearerData parameter in the SMDPP message;
Utilize SMDPP message that short message is sent to MC;
}
Then, user A just can with receive the same this short message that receives of common short message service process.
The core content of the embodiment of the invention is on the basis of existing network HLR, increase is to registration of the parameter of roaming state informing business and business processing logic: promptly during according to the handling process of standard mobility protocol process user location update message, according to being provided with of user called signaling is carried out intercept analysis at HLR.
At this moment, HLR will support following function:
1), HLR can support the signatory management of " roaming state informing business ", comprise signatory/go to contract/activation;
2), HLR has the short message transmitting capacity;
3), HLR wants to discern user's roaming character, the roaming state that promptly will have the ability to differentiate the user be in the district, internal and international;
4), HLR more wants and can send corresponding roaming state announcement information according to roaming character in the new technological process in user's position;
Below be that the basis describes how to realize the present invention just with CDMA ANSI-41D agreement flow process.
Suppose that user A is signatory and activated roaming state informing business function, as shown in Figure 1, the embodiment of the invention may further comprise the steps:
The first, the user initiates position updating request to MSC/VLR, and this MSC/VLR initiates position updating request to user attaching HLR;
This step specifically comprises as the step 1 among Fig. 2,2,
1, behind the MSC1/VLR1, initiates position updating request REGREQ outside mobile subscriber A MSC2/VLR2 in distinguishing roams into and distinguishes to MSC1/VLR1;
2, MSC1/VLR1 initiates position updating request REGNOT[MSCID1 to the ownership HLR of user A]; These message flow steps and message interface CDMA standard agreement complete and of the prior art is consistent.
The second, HLR receives this location update request message, judges whether this user roaming has taken place.
Shown in the step 3 among Fig. 2, i.e. REGCANC[MIN], specifically may further comprise the steps:
3.1, HLR receiving position update inquiry information;
3.2, judge whether this user roaming has taken place; If continue so, otherwise carry out the common process flow process; Whether HLR discerns the user according to the MSCID2/VLRID2 that preserves the MSCID1/VLRID1 that reports in the message and last time is transregional (state) roaming.
Wherein said common process flow process more specifically is meant according to the normal place of ANSI-41D protocol requirement upgrades business flow processing, in view of this standard common process flow process all is that ANSI-41D is explicitly provided, the those of ordinary skill of same domain is perfectly clear, and does not repeat them here.
3.3, HLR judge called whether signatory and activated the roaming state informing business, if carry out next step so, otherwise carry out the common process flow process.If the user is signatory and activated the roaming state informing business, then identify follow-up flow process 6, promptly step 3 need send the roaming state informing message.
No matter whether above-mentioned flow process finally needs to send SMS message, according to standard agreement, HLR initiates cancel location message to the MSC2/VLR2 of user attaching, shown in the step 4 among Fig. 2,5, specifically comprises:
4, MSC2/VLR2 deletion user profile, and feedback execution result, i.e. regcanc;
5, HLR is handed down to ownership MSC1/VLR1, i.e. regnot[Profile according to standard agreement every service profile that the user is current].
Three, whether decision sends SMS message HLR according to the roaming judged result.
If user's roaming, the HLR structure comprises the short message of current roaming state information, and this short message is sent to the MC of short message service center;
Shown in the step 6 among Fig. 2, i.e. SMDDP[MDN, SMS BearerData],
If 6 in step 2, HLR judges that the user is trans-regional roaming and contracts and activated the roaming state informing business that HLR just sends to user A with content default, that comprise the current roaming state information with the short message form so; Certainly, content of short message can be set flexibly by operator, such as for return local user from the other places, can increase out of Memory such as salutatory or weather forecast.
Then, MC sends to the user with this short message.
When finishing this step, MC will send notice to HLR, and this notice expression MC correctly receives short message just now, shown in the step 7 among Fig. 2,8,
7, the expression of MC feedback has correctly received short message; Be SMDDP[Result];
8, MC sends to user A according to the short message handling process of standard with this short message.Thereby user A can learn the notice that current roaming state has switched.
The foregoing description is at cdma network, for the GSM network, realizes that principle is identical.
