Abstract
The present invention discloses a user paging method for preventing illegal users from interfering. A mobile exchange center sends an A-interface paging request message to a base station controller after receiving a user's call request; the base station controller records electronic serial number parameters, and sends an air interface paging request message comprising an international mobile user identification code to all mobile terminals in the paging range after receiving the A-interface paging request message; the mobile terminals compare the international mobile user identification code in the air interface paging request message with the own international mobile user identification code; when the two international mobile user identification codes are coincident, the coincident mobile terminal returns an air interface paging response message. The base station controller compares an electronic serial number in the air interface paging response message with the recorded electronic serial number after receiving the air interface paging response message of the mobile terminal; when the two electronic serial numbers are coincident, the base station controller sends an A-interface paging response message to the mobile exchange center; the mobile exchange center makes an authentication; after the authentication is successful, connection between the user and the mobile terminal is established.
Description
Technical field
The present invention relates to a kind of mobile communication technology, specifically, relate to the calling user method that a kind of disabled user of preventing disturbs.
Background technology
Below with reference to Fig. 1 the detailed process of calling user in the prior art is described in detail.
Referring to Fig. 1, the detailed process of calling user is as follows in the CDMA2000 communication system:
Step 101: receive the paging request of voice, note or grouping, positioning service of this mobile subscriber terminal when the mobile switching centre (MSC) that certain mobile subscriber visits ground after, contain international mobile subscriber identity (International Mobile Subscriber Identity, paging request IMSI) to base station controller (BSC) transmission;
After step 102:BSC receives this paging request, initiate paging to mobile subscriber terminal;
Step 103: after mobile subscriber terminal is received this beep-page message, judge whether IMSI entrained in the paging request message is consistent with the IMSI of oneself, when unanimity, then to base station controller send contain IMSI, Electronic Serial Number (Electronic Serial Number, ESN) and the page-response message of authentication parameter;
Step 104:BSC sends page-response message to MSC;
Step 105:MSC carries out authentication according to the IMSI in the page-response message, ESN and authentication parameter to this user, if the authentication success is then carried out follow-up Business Processing and continued;
When authentication does not have when successful, then continue to carry out the following step:
Step 106: if failed authentication, MSC sends clear command to BSC, and indication BSC discharges this and calls out, and the originating end to business sends professional release message simultaneously, stop this business continue continue;
Step 107:BSC initiates to take out stitches to mobile subscriber terminal, discharges air resource;
Step 108: mobile subscriber terminal returns the response of taking out stitches;
Step 109:BSC returns to remove to MSC and finishes.
From said process as can be seen, as long as have identical IMSI, the paging request that mobile subscriber terminal just can response to network issues is returned page-response message by BSC to MSC.
But, in the actual operation process of Mobile Network Operator, often meet some illegal mobile phone users, the characteristics of these illegal mobile phone users are to have identical IMSI with some legal mobile phone users, but the ESN difference.This illegal mobile phone users its IMSI and ESN for network do not match, authentication must be failed after it is by normal paging, thereby cause MSC to discharge the foundation of this business, therefore, when illegal mobile phone users with legal mobile phone users is current when all being in certain professional paging range, and during this paging of response earlier of illegal mobile phone users, will cause the business of legal mobile phone users to set up.
For addressing the above problem, present technology is that MSC is carried out particular processing, basic handling mechanism is, receive the page-response message of illegal mobile phone users as MSC, and judge when its ESN is incorrect, remove this disabled user's paging to BSC, be equivalent to neglect this disabled user's page response, continue to wait for the page response of validated user.
But there is following shortcoming in this processing method:
1, increased the complexity of MSC parallel processing page response.
MSC is from receiving the page-response message of BSC, to finishing authentication, it might not be a processed continuously process, during this time, may have mutual with attaching position register (HLR), for example do not have user's data in the VLR Visitor Location Register of MSC (VLR) database, or VLR does not support authentication arithmetic.When MSC finishes in the authentication process of illegal mobile subscriber terminal at wait HLR, received the page response of legal mobile phone users again, MSC just needs a plurality of page responses of parallel processing for same paging, like this, causes logic error easily.Under certain extreme case, when having the legal mobile phone users of a plurality of illegal mobile phone users and, a plurality of mobile phone users respond paging simultaneously, in this case, MSC selects legal mobile phone users from a plurality of mobile phone users if desired, refuse other illegal mobile phone users, processing is very complicated.
2, be subjected to the restriction of BSC treatment mechanism.
The BSC equipment of different manufacturers is differentiated to the treatment mechanism of paging, and the BSC equipment of the equipment producer that has is only supported to send a page response to MSC to the paging request of some mobile phone users.Like this, when disabled user and validated user are positioned at same BSC coverage, if the response paging earlier of illegal mobile phone users, the page-response message of the legal mobile phone users in back may directly can be abandoned by BSC so, can not send to MSC.
3, the signal resource between waste MSC and the BSC.
Because page-response message to illegal mobile phone users, BSC also needs to be sent to MSC, when MSC discern this mobile phone users illegal after, need to send to the release of BSC again, so can bring adverse effect to the utilization ratio of signal resource and the flow of message.
Summary of the invention
Technical problem solved by the invention provides the calling user method that a kind of disabled user of preventing disturbs, and this method does not need base station controller or mobile switching centre are made complicated the transformation, just can solve disabled user's interference to validated user when paging.
Technical solution of the present invention comprises the steps:
Prevent that the calling user method that the disabled user disturbs from comprising the steps:

(5) mobile switching centre carries out authentication according to A interface paging response message, and authentication parameter includes international mobile subscriber identity and Electronic Serial Number;
(6) after the authentication success, set up being connected of user and portable terminal.
Preferably, step (4) further comprises:
When illegal air interface paging response message prior to the response of legal air interface paging response message, base station controller abandons this illegal air interface paging response message, up to the air interface paging response message response paging of validated user.
Preferably, step (4) further comprises:
When the air interface paging response message response of the air interface paging response message of validated user prior to the disabled user, base station controller sends A interface paging response message to mobile switching centre, this A interface paging response message contains international mobile subscriber identity and Electronic Serial Number, and base station controller no longer receives the air interface paging response message of the portable terminal that contains identical international mobile subscriber identity.
Preferably, in the step (1), call request comprises voice, note, grouping or positioning service.
Preferably, in the step (3), the air interface paging response message that portable terminal returns contains international mobile subscriber identity and Electronic Serial Number.
Preferably, in the step (5), behind the A interface paging response message of mobile switching centre's As-received station control, do not need to judge again the legitimacy of Electronic Serial Number.
The present invention makes BSC oneself just can judge and mask disabled user's page response, and need not to carry out extra complicated special processing by MSC again by increase effective identification disabled users' such as ESN data parameters in paging request message.
Solve disabled user's interference problem to validated user when the paging by the inventive method and have following advantage:
1, change simply more effective to MSC than original technology.
Because MSC has all obtained paged user's parameters such as ESN when sending the paging request, so the present invention do not need MSC is carried out complicated change, only need with the interface message of BSC in increase these parameters and get final product.
Though 2 need BSC to write down and compare parameter such as ESN, in the prior art of comparing, need some BSC producer to change a paging and only return a page response mechanism and want much simple to MSC.
3, for disabled user's page response, between the interface of BSC and MSC, do not transmit, save signal resource and message traffic between BSC and the MSC.
Description of drawings
Fig. 1 is the flow chart of mobile phone users paging in the prior art;
Fig. 2 is the flow chart of preferred embodiment of the present invention paging.
Embodiment
When MSC initiates subscriber paging, with user's ESN etc. other effectively data parameters and IMSI of identification disabled users together bring BSC, carry out record by BSC.When BSC receives page response from the user, at first carry out the isoparametric legitimacy verification of ESN, the page response for disabled user's terminal is shielded by BSC.
With reference to shown in Figure 2, in the preferred embodiment, the A interface is the interface between mobile switching centre and the base station controller, and air interface is the interface between base station and the mobile phone terminal.
Prevent that the calling user method that the disabled user disturbs from comprising the steps:
Step 201: after the call request of user to portable terminal received by mobile switching centre (MSC), send A interface paging request message, contain Electronic Serial Number (ESN) parameter in this A interface paging request message to base station controller (BSC).
Specifically, when MSC that certain mobile subscriber visits ground receive this user's voice, note or terminals such as grouping, positioning service are called for ask after, in the paging request message (PagingRequest) that sends to BSC, except that original IMSI parameter, need to increase the ESN parameter.
Step 202: after base station controller (BSC) is received A interface paging request message, recording electronic serial number (ESN) parameter.
Step 203:BSC all portable terminals in paging range send air interface paging request message, contain international mobile subscriber identity (IMSI) in this air interface paging request message.
Step 204: after the portable terminal in the paging range is received air interface paging request message, portable terminal compares international mobile subscriber identity in the air interface paging request message (IMSI) and self international mobile subscriber identity (IMSI), if unanimity then return air interface paging response message.The air interface paging response message that portable terminal returns contains IMSI, ESN and other parameter.
Here hypothesis has the IMSI of two terminals of validated user and disabled user consistent with the IMSI in the air interface paging request message, and illegal terminal is prior to validated user terminal response air interface paging request message.
Step 205: after the air interface paging response message of the portable terminal that base station controller (BSC) is received, the Electronic Serial Number that has write down (ESN) in Electronic Serial Number in this air interface paging response message (ESN) and the step 202 is compared.If it is inconsistent that BSC judges two ESN, then this air interface paging response message is regarded as disabled user's air interface paging response message by BSC, and BSC abandons the disabled user's that receives air interface paging response message.
Step 206: the terminal response air interface paging request message of validated user, send air interface paging response message.
After step 207:BSC receives the air interface paging response message of legal terminal, the ESN of record in its ESN and the step 202 is compared, find consistent, send A interface paging response message (PagingResponse) to MSC, have IMSI, ESN and other authentication parameters that the user terminal band is come in this A interface paging response message.
Step 208:MSC carries out higher level authentication according to IMSI, ESN in the A interface paging response message and other authentication parameters to this validated user.
After MSC receives BSCA interface paging response message, do not need to judge again the isoparametric legitimacy of ESN, directly carry out higher level authentication using.
Step 209: if the authentication success, MSC carries out follow-up Business Processing and continues.
Like this, being connected of user and portable terminal set up successfully, professional normal foundation of validated user.
When authentication does not have when successful, then continue to carry out the following step:
A:MSC sends clear command to BSC, and indication BSC discharges this and calls out, and the originating end to business sends professional release message simultaneously, stop this business continue continue;
B:BSC initiates to take out stitches to mobile subscriber terminal, discharges air resource;
C: mobile subscriber terminal returns the response of taking out stitches;
D:BSC returns to remove to MSC and finishes.
When responding air interface paging request message as a plurality of illegal terminal users whiles or prior to the legal terminal user, the inventive method can all mask all illegal terminal users by BSC, receives only legal terminal user's air interface paging response message.After BSC confirms that according to the parameters such as ESN in the terminal air interface paging response message user is illegal, shield illegal air interface paging response message successively, up to legal users air interface paging response message response, transmit A interface paging response message again to MSC this user that continues to continue.This processing method does not need MSC and BSC are carried out complexity transformation, and avoid the signal resource that causes in the interface of disabled user's page response between BSC and MSC in the paging and the waste of message traffic, simply solved the problem that the disabled user disturbs legal subscriber paging efficiently.
When illegal air interface paging response message prior to the response of legal air interface paging response message, base station controller abandons this illegal air interface paging response message, up to legal users response air interface paging request message; When legal air interface paging response message responds prior to illegal air interface paging response message, base station controller sends A interface paging response message to mobile switching centre, this A interface paging response message contains international mobile subscriber identity and Electronic Serial Number, and base station controller no longer receives the air interface paging response message of the portable terminal that contains identical international mobile subscriber identity.
