Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in more detail by the following examples.

The main thought of the present invention is, utilize Number Assignment Module (the NumberAssignment Module of a wireless terminal in the professional change of the parameter management of eating dishes without rice or wine (OTAPA) same wireless terminal in the aerial download technology, NAM) parameter, thus identical wireless terminal eliminated.

Wireless terminal of the present invention can be MS, also can be fixed radio terminal (FWT).On the one hand, wireless terminal can be the wireless terminal in wireless terminal, the wireless terminal in the cdma system or Wideband Code Division Multiple Access (WCDMA) (WCDMA) system in the gsm system.On the other hand, wireless terminal can be the wireless terminal of separation between machine and card, also can be the wireless terminal of machine engaging one.

The NAM parameter can be international mobile subscriber identity (International Mobile SubscriberIdentity, IMSI) or KI (A_Key) etc., or their combination.

Be the example explanation with the NAM parameter among the change MS below.Shown in Figure 1 is the related mobile communications network logic networking diagram of the embodiment of the invention.Referring to Fig. 1, the mobile communication network device that present embodiment relates to comprises: a MS among the identical MS, base station sub-system (BSS), mobile switching center (MSC/VLR), attaching position register/AUC (HLR/AC), Customer Service Center (CSC), the parameter management entity of eating dishes without rice or wine (Over-the-Air Service ProvisioningFunction, OTAF), can further include accounting system.

Fig. 2 is for utilizing the schematic flow sheet of NAM parameter among the OTA technology change MS in the embodiment of the invention.With reference to Fig. 2, this flow process may further comprise the steps:

Step 101, MS is initiated to the calling of CSC, and perhaps CSC is initiated to the calling of MS, and the calling of setting up between MS and the CSC connects.Wherein, can be accounting system by analyze call log information, detect have identical portable terminal after, send change directive to CSC, and after CSC receives the change directive of accounting system, make a call to MS.Or mobile phone users is found to exist maybe may have identical portable terminal by often receiving abnormal call, initiatively makes a call to CSC then.

After setting up the calling connection, can further include CSC carries out password authentification to MS process.For example, CSC imports the service password of this MS by the voice suggestion user, and the user is by MS input password and send to CSC, and CSC judges whether the password of being inputed is correct, if correct, then by password authentification, execution in step 102; Otherwise, not by password authentification, can the prompting user after process ends.That change in the present embodiment is the MS that password authentification is passed through, and goes up in actual applications and also can change password authentification unpassable MS.

Step 102, CSC sends the request of change NAM parameter to OTAF.

Step 103, OTAF confirms needs initiation OTAPA flow process according to this request, for obtaining the current routing iinformation of user, to the HLR/AC request of sending SMS message (SMSREQ) message, comprising MS sign (MSID), Electronic Serial Number (ESN) and professional indication parameters such as (SRVIND).

Step 104, HLR/AC returns the short message address (SMSADDR) of the current MSC/VLR of living in of MS in response message smsreq.

Step 105, data-message (OTASP DataMessage) the parameter management request (OTAPA Request) of promptly eating dishes without rice or wine that provides is provided OTAF structure air traffic, and it is packaged in short message carrying data (SMS_BearerData) parameter, send to MSC/VLR by short message point-to-point (SMDPP) message.Also comprise MSID, ESN, SRVIND, behavior sign indicating number (ACTCODE) etc. in the SMDPP message, wherein ACTCODE instruct MS C/VLR carries out resource allocation.

Step 106, if MS is in Idle state, MSC/VLR need set up channel for MS, if the user is in conversation state, then can directly use the current business channel.In the present embodiment, MS and CSC are in talking state, so MSC/VLR directly uses current Traffic Channel.MSC/VLR is OTAPA Request from SMS_BearerData parameter acquiring OTASP Data Message, and sends MS to by BSS.

If the NAM of MS is in the protection attitude, then MS returns response message network is verified, to prevent to be subjected to the interference of illegal network.BSS receives the idle message of MS and is bundled in User Part (ADDSUserPart) parameter, is sent to MSC/VLR by transmitting (ADDS Deliver) message, and execution in step 107 is to the network verification process of step 111 then.

If the NAM of MS is in the protection attitude; then MS directly returns response message; BSS receives the idle message of MS and is bundled in the ADDSUserPart parameter; be sent to MSC/VLR by ADDS Deliver message; execution in step 112 and subsequent step thereof then, promptly not execution in step 107 to the network verification process of step 111.

Step 107, the OTASP Data Message that MSC/VLR obtains in the ADDSUserPart parameter is OTAPA response (OTAPA Response), and it is bundled in the SMS_BearerData parameter, smdpp sends to OTAF by response message.

Step 108, OTAF checks the message content of eating dishes without rice or wine in the SMS_BearerData parameter, finds that the NAM of MS is protected, therefore sends OTASP request (OTASPREQ) message initiated authentication verification process to the HLR/AC of correspondence.

Step 109, HLR/AC calculates and generates base station authentication parameter (AUTHBS), and returns to OTAF in response message otaspreq.

Step 110, OTAF structure OTASP Data Message promptly confirms request (ValidationRequest), wherein comprising value is the authentication OTAPA parameter (AUTH_OTAPA) of AUTHBS.OTAF is packaged in Validation Request in the SMS_BearerData parameter, sends to MSC/VLR by SMDPP message.Also comprise parameters such as MSID, ESN, SRVIND in the message.

Step 111, MSC/VLR is Validation Request from SMS_BearerData parameter acquiring OTASP Data Message, and is sent to MS by BSS.

MS calculates AUTHBS after receiving message, if identical with AUTH_OTAPA, thinks that then network is legal, returns response message.BSS receives the MS idle message, and it is bundled in the ADDSUserPart parameter, is sent to MSC/VLR by ADDS Deliver message.

Step 112, the OTASP Data Message that MSC/VLR obtains in the ADDSUserPart parameter is Validation Response, and it is bundled in the SMS_BearerData parameter, smdpp sends to OTAF by response message.

Step 113, OTAF begins to start NAM parameter change process, structure OTASP DataMessage is download request (Download Request), and it is packaged in the SMS_BearerData parameter, send to MSC/VLR by SMDPP message, also carry the new NAM parameter of CSC request change in the message.

Step 114, MSC/VLR transmits OTASP Data Message message to MS by BSS, and MS returns response message after receiving new NAM parameter, and BSS sends ADDSDeliver message to MSC/VLR.

Step 115, the OTASP Data Message that MSC/VLR obtains in the ADDSUserPart parameter promptly downloads response (Download Response), and is bundled in the SMS_BearerData parameter, and smdpp sends to OTAF by response message.Above-mentioned steps 113 to step 115 sends new NAM parameter to MS for OTAF, or perhaps MS downloads new NAM parameter.

As those skilled in the known, in concrete A_Key change flow, can relate to repeatedly the mutual and random number of SMDPP and calculate back and forth,, not be explained in detail here because corresponding regulation is arranged in standard.

Step 116, OTAF need to confirm MS with the NAM parameter write storage unit of downloading, the memory cell of SIM card that this MS installed or UIM card for example, structure OTASP Data Message promptly carries out request (Commit Request), and be packaged in the SMS_BearerData parameter, send to MSC/VLR by SMDPP message.

Step 117, MSC is bundled to the SMS_BearerData content of parameter in the ADDSUserPart parameter, sends to BS by ADDS Deliver message.BS obtains the ADDSUserPart content of parameter, sends OTASP Data Message message to MS.

MS successfully writes the memory cell of MS with the parameter of downloading, and responds corresponding OTASP DataMessage.BS sends ADDSDeliver message to MSC, comprises OTASP Data Message message content among the parameter A DDSUserPart.

Step 118, MSC/VLR structure OTASP Data Message promptly carries out response (CommitResponse), and it is bundled in the SMS_BearerData parameter, and smdpp sends to OTAF by response message.Above-mentioned steps 116 to step 118 is that the OTAF instruct MS is with the parameter write storage unit.

Step 119, OTAF determine to need finishes the OTAPA process, and structure OTASP Data Message wherein is packaged in OTAPA ending request (OTAPA Request[STOP]) in the SMS_BearerData parameter, sends to MSC/VLR by SMDPP message.

Step 120, MSC/VLR transmits OTASP Data Message to MS.

Step 121, the OTASP Data Message of MSC/VLR packing MS response, and OTAPA response (OTAPA Response) is bundled in the SMS_BearerData parameter, smdpp sends to OTAF by response message.Above-mentioned steps 119 to step 121 is the OTAPA flow process between end OTAF and the MS.

To step 131, OTAF utilizes the OTAPA flow process to change the NAM parameter among the MS by step 103.

Step 122, OTAF will operate successful result and send to CSC.

Step 123 discharges CSC and is connected with calling between the MS.Why keep calling out being connected to change to operate always and finish, its objective is that the user in order to ensure user who carries out password authentification and actual change is same user.

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 done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
