Abstract

This invention discloses a method for realizing beep users, including: A, a called mobile exchange center sends a beep request containing IMSI to a called user by a base station controller, B, the called user utilizes IMSI to connect it to the base station controller and sends a beep response containing ESN via the controller, C, the center receives the beep response and judge if the ESN is the same with that stored in the network side, if so, the normal process is carried out, otherwise, the call connection is removed to return to step A. This invention adds ESN in the called user response information, so that the call MSC judges if the user is legal based on said ESN, if not, it calls the user many times, which avoids interference of illegal users to legal users when illegal users are called.

Description

A kind of method that realizes calling user

Technical field

The present invention relates to the mobile communication technology field, be meant a kind of method that realizes calling user especially.

Background technology

Referring to shown in Figure 1, the detailed process of calling user is as follows in code division multiple access (CDMA) system:

Step 101: receive the paging request of caller MSC when called mobile switching centre (MSC) after, called MS C sends the paging request (Paging Request) that contains IMSI to base station controller (BSC);

After step 102:BSC receives this paging request, send the beep-page message (Page Message) that contains international mobile subscriber identification (IMSI) to the user;

Step 103: after the user receives this beep-page message, send the page-response message (Paging Response Message) that contains IMSI, ESN and authentication parameter to BSC;

After step 104:BSC receives this page-response message, send page response (PagingResponse) to MSC.

Step 105: after MSC receives this page response, according to wherein IMSI, ESN and authentication parameter this user is carried out authentication, if failed authentication, then execution in step 106, otherwise, call out to connect and set up, jump out this flow process;

Step 106: called MS C sends the request of taking out stitches (Clear Command) to BSC;

Step 107:BSC sends disconnect command (ReleaseOrder) to the user after receiving this request of taking out stitches;

Step 108: after the user receives this disconnect command, send disconnect command to BSC;

Step 109:BSC removes circuit, and sends to take out stitches to called MS C and finish message.

From said process as can be seen, as long as have identical IMSI, the BSC that the user just can the response to network side.But, in the actual operation process of Mobile Network Operation merchant, often meet a class disabled user, this class disabled user's characteristics are that the IMSI of IMSI and validated user is identical, the ESN difference.And because this user is illegal, authentication must be failed.Behind failed authentication, with dismantling call, this end of calling.

Therefore, all be in the paging range of certain calling,, will cause the calling of validated user to set up if the disabled user responds this paging earlier when disabled user and validated user are current.Thereby the rights and interests of validated user can not get effective guarantee.

Summary of the invention

In view of this, the object of the present invention is to provide a kind of method that realizes calling user, solve disabled user's interference to validated user when called.

In order to achieve the above object, the invention provides a kind of method that realizes calling user, this method comprises:

A. called mobile switching centre sends the paging request that contains IMSI by base station controller to the called subscriber;

B. the called subscriber who receives this paging request utilizes IMSI and base station controller foundation calling to be connected, and sends the page response that contains the ESN parameter to called mobile switching centre by base station controller;

C. after this page response is received by called mobile switching centre, judge whether the corresponding ESN of wherein ESN and this called subscriber of network side preservation is identical, if identical, then carries out normal handling, otherwise, remove the calling connection of setting up among the step B, return steps A.

Set in advance number of calls threshold value, if the ESN in the page response and network side preservation inequality among the step C, the calling of setting up in removing step B further comprises after connecting:

Whether C1, called mobile switching centre judge the number of calls greater than threshold value, if greater than, then jump out this flow process, otherwise, execution in step A.

Normal handling comprises described in the step C: called mobile switching centre carries out authentication to the user, if authentication is passed through, allow the user to converse, otherwise dismantling call connects.

Further comprise IMSI described in the step B in the page response, then the ESN of this called subscriber's correspondence of network side preservation described in the step C obtains by IMSI.

The present invention is by increasing ESN in called subscriber's response message, whether make called MS C judge this user according to this ESN is validated user, if not validated user, calling user repeatedly, thereby solved disabled user's interference to validated user when called, the calling that has guaranteed validated user is effectively normally set up, and has effectively ensured the interests of validated user.Simultaneously, improved network quality, can reduce the complaint of client operator.

Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.

Core concept of the present invention is: increase ESN the called subscriber in the page response that network side returns, network carries out verification to user's ESN number, if the user that paging is arrived is illegal, repeats to send beep-page message, repeatedly calling user.

Referring to shown in Figure 2, realize that method of the present invention may further comprise the steps:

Step 201: called mobile switching centre sends the paging request that contains IMSI by base station controller to the called subscriber;

Step 202: the called subscriber who receives this paging request utilizes IMSI and base station controller foundation calling to be connected, and sends the page response that contains IMSI and ESN to called mobile switching centre by base station controller;

Step 203: after this page response is received by called mobile switching centre, utilizing wherein, IMSI obtains corresponding ESN from network side, judge whether the ESN that receives is identical with the ESN of network side preservation, if it is identical, then carry out normal handling, otherwise, remove the calling of setting up in the step 202 and connect, return step 201.

Certainly, also can set in advance number of calls threshold value, for a calling, called MS C metered call called subscriber's number of times is when the ESN of ESN and network side preservation in the page response that MSC receives is inequality, after removing the calling connection of having set up, whether called mobile switching centre can judge the number of calls greater than the threshold value that sets in advance, if greater than, then approve with terminated call, otherwise, call out once more.

Describe technical scheme of the present invention in detail referring to the drawings and specific embodiments.

Referring to shown in Figure 3, present embodiment is the process of calling user in cdma system.Its concrete processing procedure is as follows:

Step 301: called MS C sends the paging request (PagingRequest) that contains IMSI to BSC.

After step 302:BSC receives this paging request, send the beep-page message (Page Message) that contains IMSI to the called subscriber.

Step 303: the called subscriber who receives this beep-page message sends the page-response message (Paging Response Message) that contains IMSI, ESN and authentication parameter to BSC;

After step 304:BSC receives this page-response message, send page response (PagingResponse) to MSC.

Step 305: after MSC receives this page response, judge whether ESN wherein is identical with the ESN of network side preservation, if identical, execution in step 310, otherwise, remove the calling of having set up and connect execution in step 306.

Step 306: called MS C sends the request of taking out stitches (Clear Command) to BSC.

Step 307:BSC sends disconnect command (ReleaseOrder) to the user after receiving this request of taking out stitches.

Step 308: after the user receives this disconnect command, send disconnect command to BSC.

Step 309:BSC removes circuit, and sends to take out stitches to called MS C and finish message, returns step 301.

Step 310: called MS C carries out authentication according to called subscriber IMSI, ESN and authentication parameter to this user, if the authentication success, then call setup is jumped out this flow process, otherwise, call failure.

In the above-described embodiments, step 301～304 are the called paging user procedures, MSC increases the judgement to page response user's ESN in step 304, if the ESN that the user registers in advance among this ESN and the called MS C is inconsistent, can conclude that then this user is illegal user.So, when utilizing method of the present invention to call out, if the disabled user responds earlier, after called MS C will confirm that the user is illegal according to the ESN in the response, initiate to remove all connections of disabled user, and carry out paging once more, wait for the response of validated user, up to the validated user response, this user again continues.

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.
