Abstract

The invention discloses a method of ascribing to HLR when subscribers who have one card with multiple numbers roam to a subscription area, the method comprises such steps that (a) after the subscribers access a system, a service mobile switching center originates the request of operations and starts to operate by routing to the home location register of the account opening place of the subscribers via the international mobile subscriber identifier (IMSI) of the subscribers, and after the success operation, the next step is carried out; the mobile switching center hereafter referred to as MSC and the home location register hereafter referred to as HLR; (b) if the subscribers subscribe the HLR of the current location of the subscribers, the HLR of the account opening place of the subscribers fabricates a virtual local operation request, the destination address is the address of the HLR of the current location of the subscribers and the source address is the address of a service MSC, so that the request of the virtual local operation is transmitted to the subscription HLR; (c) after the HLR of the current location of the subscribers receives the request of the local operation, the operation response is returned to the service MSC; (d) after receiving the response message, the MSC processes the response message so as to obtain the subscription information of the roaming area of the subscribers.

Description

The implementation method of user with one card multi number belonging to HLR when roaming to contract signing place

Technical field

The present invention relates to mobile communication core net field, particularly the one-card multi-number user attaching is in the method for HLR.

Background technology

High speed development along with mobile communication technology and market, increasing business people need shuttle in different areas or country, and mobile phone is as the communication modes of convenient and general, brings long-distance, the roaming telephone expenses of great number to the client, and the telephone expenses of great number also influence business and carry out simultaneously.This problem can apply for that a card and a plurality of mobile number solve by the client, and this promptly is the said One Card Multinumber of the present invention.

The mode of One Card Multinumber is a lot, has a kind of user of being to have only a mobile phone, a mobile phone card, bundlees the situation of a plurality of mobile numbers.Fig. 1 is wireless network networking structure figure of the present invention, MSC1 (mobile services switching centre) and HLR1 (attaching position register) belong to service area 1, MSC2 and HLR2 belong to service area 2, the voice of two service areas link to each other by GMSC/STP (GMSC (gateway mobile switching center)/Signalling Transfer Point) with signaling, wherein dotted line is represented signaling link, solid line is represented voice speech channel, and the cellphone subscriber uses local mobile number respectively at service area 1 and service area 2.For supporting the One Card Multinumber user normally to use local mobile number to finish business such as calling in a plurality of areas, do not produce wandering fee, need the HLR of user attaching in a plurality of areas.For realizing a plurality of HLR of user attaching, when the user moves to any MSC, require MSC to initiate operations such as registration, authentication to a plurality of HLR of user attaching, and this is not normal protocol processes flow process, therefore all MSC want the upgrade software support in the net, this is very difficulty, very big, the extremely difficult realization of cost obviously, more is not that operator wishes to realize.

Summary of the invention

Technical problem to be solved by this invention provides a kind of implementation method of user with one card multi number belonging to HLR when roaming to contract signing place.

In order to solve the problems of the technologies described above, the implementation method of ownership attaching position register when the invention provides a kind of one-card multi-number user and roaming into contract signing place may further comprise the steps:

(a) behind the subscriber access system, serving mobile switching center is initiated operation requests, being routed to user's ground attaching position register of opening an account with user's international mobile subscriber identity IMSI operates, carry out next step after operating successfully, described mobile switching centre is hereinafter to be referred as MSC, and described attaching position register is hereinafter to be referred as HLR;

(b) the current on-site HLR if the user has contracted, the then described user ground HLR constructing virtual local operation request of opening an account, destination address is the address of the current location HLR of user, and source address is the address of service MSC, and virtual local operation request is sent to signatory HLR;

(c) after user location HLR receives the local operation request, to the response of service MSC return;

(d) described MSC handles it after receiving response message, obtains the CAMEL-Subscription-Information of user roaming place.

Further, said method also can have following characteristics: in described step (a), if the HLR operation failure, then to service MSC return failure response message.

Further, said method also can have following characteristics: in described step (b), if the user does not have other signatory HLR, then return service MSC operation success response.

Further, said method also can have following characteristics: in described step (c), before the constructing virtual operation requests, judge with user location HLR and receive whether the time interval of the operation requests message of service MSC reaches default time value, if, then send the pseudo operation request, otherwise, wait for that the described time interval sends the pseudo operation request after arriving the Preset Time value again.

Further, said method also can have following characteristics: described time value is the maximum duration of the wait-for-response of MAP agreement regulation.

Further, said method also can have following characteristics: after described step (e), further comprising the steps of: judge user non-current on-site other HLR that whether contracted, if, constructing virtual other places operation requests then, destination address is the address of non-current on-site other HLR.

Further, said method also can have following characteristics: described registration, authentication or the position of being operating as upgraded.

Adopt that the present invention can make that the user registers at the service area of signatory arbitrary HLR, after position renewals, authentication etc. operates successfully, the while can also be initiated these operations such as grade to other all HLR that contract.

Embodiment

The present invention invents the user ground HLR (attaching position register) that opens an account the user and serves MSC (mobile switching centre), initiates operation such as registrations grade to other signatory HLR, thereby solves the problem of a plurality of HLR of user attaching.

In conjunction with Fig. 2 and Fig. 3, the message flow that the One Card Multinumber user initiates to register is described, position renewal, authentication operations etc. also are same as this flow process, and other flow processs are with the existing protocol flow process.

For convenience of description, if service MSC in the local roaming list of certain HLR, claims this HLR to be " the local HLR of service MSC ".

The present invention is to the requirement of operator, and just upgrading, all carry out the HLR software in this professional area.For accounting system, except the CAMEL-Subscription-Information of this HLR that will contract to any one HLR simultaneous user that the One Card Multinumber user contracts, also will be to user the open an account HLRIN of other all HLR that ground HLR simultaneous user contracts and this locality roaming MSCIN tabulation of these HLR, described HLRIN and MSCIN are respectively the addresses of attaching position register and mobile switching centre, be used for MAP message route, generally distribute by operator.

After network must be guaranteed to open an account ground HLR registers successfully, just can initiate the log-on operation of other each signatory HLR by the ground HLR agency that opens an account, in addition, the local HLR of service MSC if the user has contracted, then initiate log-on operation to this HLR earlier, so that service MSC obtains the CAMEL-Subscription-Information of user roaming place, use local mobile number to rise and exhale.

Relation between all HLR that certain service MSC that the user inserts and user contract (comprising the ground HLR that opens an account) has only two kinds, and a kind of is that service MSC is the local MSC (as Fig. 2) of certain HLR of contracting of user, and for example the signatory Nanjing of user also roams into Nanjing; Another kind is that service MSC is not any HLR of contracting of user local MSC (as Fig. 3) of (comprising the ground HLR that opens an account), as user not signing Shanghai, but roams into Shanghai.

The flow process of first kind of situation as shown in Figure 2, MSC1 is user's service MSC, user contract HLR, HLR1 and HLR2, wherein, HLR be the user open an account ground HLR, HLR1 is MSC1 location HLR, HLR2 is the strange land HLR that is different from HLR and HLR1, and registering flow path may further comprise the steps:

Step 201, the One Card Multinumber subscriber access system, service MSC1 initiates the registration request, with user IMSI (international mobile subscriber identity) be routed to the user open an account ground HLR register, if the failure of HLR log-on operation is then returned the registration failure response message to MSC1, flow process finishes, otherwise carries out next step;

Step 202 judges whether to also have other signatory HLR, if, carry out next step, otherwise, service MSC1 registration success response returned;

If other signatory HLR are arranged, then finish local HLR registration earlier, finish nonlocal HLR registration again; If there are not other HLR ownership to illustrate that then the user only belongs to the ground HLR that opens an account.

Step 203, whether judge wherein has the current location HLR of user, if, execution in step 204, otherwise execution in step 207;

Step 204, the local registration request of HLR constructing virtual, the HLRIN of the HLR1 that use HLR preserves (the local HLR of service MSC) is as destination address, and virtual this locality registration request that structure is good sends to HLR1;

The virtual local register request message content of HLR structure is removed the HLRIN of the HLR1 that uses the HLR preservation as destination address, so that be routed to outside the HLR1, and the registration request of sending fully with MSC1, source address is still the MSCIN of MSC1.

The user can trigger by accounting system and revise HLR, makes it preserve the HLRIN of all signatory HLR.

Step 205, HLR1 handles virtual registration message with handling the normal registration message flow after receiving local registration request, returns register response to MSC1;

Step 206, MSC1 handles it after receiving response message, obtains the CAMEL-Subscription-Information of user roaming place, exhales so that use the subscriber's local mobile number to rise;

Step 207, the other places registration request of HLR constructing virtual, the HLRIN of the HLR2 that preserves with HLR sends to HLR2 as destination address.

First returns to service MSC in order to guarantee first virtual register response, and this request will wait for after HLR sends previous virtual registration message that " MAP waits for the maximum duration of register response " of Map (MAP) agreement regulation sends to HLR2 afterwards.This request message source address is not done requirement, can fill in the HLRIN of HLR, and the response message of HLR2 can turn back to HLR like this, and just HLR does not handle the response message that HLR2 returns.Other subsequent treatment are handled with MAP.

The flow process of second kind of situation as shown in Figure 3, MSC1 is user's service MSC, signatory HLR of user and HLR2, wherein, HLR be the user open an account ground HLR, HLR1 is MSC1 location HLR, HLR2 is the strange land HLR that is different from HLR and HLR1, and registering flow path may further comprise the steps:

Step 301, behind the One Card Multinumber subscriber access system, service MSC1 initiates the registration request, is routed to the user ground HLR that opens an account with user IMSI;

Step 302 is after HLR carries out the normal registration operation, if the local HLR (HLR1) of user not signing MSC1 then directly returns register response and gives MSC1;

Step 303 judges whether the user also has other signatory HLR, if (as HLR2 among the figure) carries out next step, otherwise this flow process finishes;

Step 304, the other places registration request of HLR constructing virtual, the HLRIN of the HLR2 that preserves with HLR is routed to HLR2 as destination address;

This request will be waited for a period of time after HLR receives the register request message of MSC1 and be sent, so that the enrollment response message of HLR2 is not handled by MSC1, the time of wait can be " MAP waits for the maximum duration of register response " of Map agreement regulation.The registration request that the MAP content of this message is sent with MSC1, the HLRIN of the HLR2 that preserves with HLR is as destination address, so that be routed to HLR2, source address is not done requirement, can be the HLRIN of HLR, just HLR does not handle the response message that HLR2 returns.Other subsequent treatment are handled with MAP.
