Abstract
The invention discloses a method which solves a problem that the service can not be used after the subscriber GPRS service is changed. The method of the invention adopts two proposals to solve the problem of a terminal that a PS Attach flow is not re-started before re-botting: proposal 1: the type in the HLR used for closing and starting the GPRS function of the terminal is modified, the closing is changed into cancelling the tying of terminal APNID, the network accessing authorization of PS domain is remained, and the starting is changed into the re-tying of APNID; the proposal 2: the reason value of message requested by SGSN refusing terminal is changed into the accessing failure caused by other unusualness.
Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the professional after changing method that can't use of user's gprs service.
Background technology
The next complete gprs service flow process of normal condition will be passed through following five key steps:
Step 1, PS Attach flow process;
Step 2, PDP activation;
Step 3, set up that TCP connects and the Transmission TCP packet;
Step 4, PDP deactivation process;
Step 5, PS Deattach flow process;
PS Attach success flow process is seen shown in Figure 1.In PS Attach flow process, SGSN is accomplished to the authentication of HLR and obtains the PS subscription data.
PS Attach flow process is the basic procedure that terminal is used GPRS.If do not finish this flow process, follow-uply just can not carry out PDP activation, also can not set up TCP and connect and send the tcp data bag.
The change of user's gprs service function is at present all carried out in HLR.The prior art scheme all adopts the network insertion pattern (NAM) of modification user in HLR to realize to closing and opening of user GPRS function.
When attempting initiating the gprs service failure, PS Attach flow process is seen Fig. 2 as the user who does not possess the gprs service authority (the GPRS function as the user is closed the back).Mobile phone is initiated " Attach Request " Attach Request message to SGSN, through sign identification " Identity Request " (optional) and authentication " Authentication Request " (optional) flow process, HLR notice SGSN inserts user data (IMSI and GPRS subscription data).Because this user does not have the access capability in PS territory, SGSN returns " Attach Reject " message to the user, refusing user's adhere to request.
The defective of prior art: when the user who does not possess the gprs service authority attempts initiating gprs service, after the PS Attach failure, mobile phone can be received SGSN " Attach Reject " message, and the cause value in the message is 7 (" GPRSSERVICES NOT ALLOWED ").According to the ETSI standard, in case receive this refuse information, mobile phone just is changed to " GU3ROAMING NOT ALLOWED " with self " GPRS update mode ", and the P-TMSI that stores in the deletion mobile phone, P-TMSI signature, RAI and GPRS ciphering key sequence number.So far mobile phone thinks that this SIM card do not have the gprs service ability.Do not drive mobile phone if do not close again, just can not initiate any PS Attach flow process once more.
Consider from user's perception angle, after showing as the user who does not possess the gprs service function and attempting initiating the gprs service failure,,, can be in the state that can't adhere to GPRS network always there not be the pass to open under the prerequisite of mobile phone even opened the gprs service function afterwards.Have only the user to close out mobile phone again, just can adhere to GPRS network.This defective has influenced GSM user to a certain extent in gprs service use perception after changing.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is exactly to make the GSM user with gprs service function after attempting initiating the gprs service failure, as the gprs service functional rehabilitation, need not to close out again mobile phone and just can normally use gprs service.
For achieving the above object, technical scheme of the present invention is achieved in that
The professional after changing method that can't use of a kind of user's of solution gprs service is characterized in that:
The user initiates to adhere to request;
The gprs service function is not opened, the binding of HLR cancellation user APNID, the network insertion authority in reservation user's PS territory; Perhaps, the gprs service function is not opened, and SGSN returns cause value, and mobile phone continues to attempt carrying out again network attachment;
The gprs service functional rehabilitation, the user normally uses gprs service
The professional after changing method that can't use of above-mentioned solution user gprs service, change the mode of closing and opening user GPRS function among the HLR: user GPRS function is closed the binding into cancellation user APNID, keeps the network insertion authority in user's PS territory; User GPRS function is opened and is bound APNID again for the user.
The professional after changing method that can't use of above-mentioned solution user gprs service, revising in SGSN is correlated with adheres to the Reason For Denial value: former cause value " GPRS SERVICES NOT ALLOWED " is revised as " Mandatoryinformation element error ", " Information element non-existent or notimplemented ", " Conditional IE error ", " Protocol error ", " unspecified " or the like.
This method can reach following effect by the modification to the conventional network equipment handling process:
A, do not have a gprs service function GSM user after attempting initiating the gprs service failure, if opened the gprs service function afterwards, need not to close out again mobile phone and just can normally use gprs service, improved the use perception of user's gprs service;
B, can not bring any influence to the user who opens GPRS;
C, GPRS user's all kinds of service application are had no effect.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
The present invention proposes technical scheme following two kinds of implementations:
Mode one: change the mode of closing and opening user GPRS function among the HLR.
At present, the change of user's gprs service function is all carried out in HLR.Closing and open all of user GPRS function realizes by the user network access module of revising among the HLR (NAM).[the user network access module that defines in HLR has two kinds: CS (Circuit Switched) territory and PS (Packet Switched) territory].The network insertion authority mode of closing employing cancellation user PS territory of original GPRS function; The network insertion authority of recovering user PS territory is adopted in the unlatching of GPRS function, and binds APNID again.
The mode of closing and opening user GPRS function among the new HLR is in the following way: 1. user GPRS function is closed the binding into cancellation user APNID, keeps the network insertion authority in user's PS territory; 2. user GPRS function is opened and is bound APNID again for the user.New and old scheme contrasts the new and old scheme of the GPRS function change that sees the following form.
| New departure | Original scheme | |
| The GPRS function is closed | The binding of cancellation user APNID, the network insertion authority in reservation user's PS territory | The network insertion authority in cancellation user PS territory |
| The GPRS function is opened | Again bind APNID | Recover the network insertion authority in user PS territory, and bind APNID again |
Mode two: in SGSN, revise the relevant Reason For Denial value of adhering to.
Adhere to request when the user's initiation that does not possess the gprs service authority, after the PS Attach failure, SGSN can return " Attach Reject " message, and wherein cause value is 7 (" GPRS SERVICES NOT ALLOWED ").SGSN revises this cause value, avoids mobile phone to receive being handled to cause not reattempting behind this Reason For Denial code carrying out network attachment again.Cause value can be revised as 96:Mandatory information element error, 99:Information element non-existent or not implemented,, 100:Conditional IEerror, 111:Protocol error, unspecified or the like.
Above-mentioned two kinds of schemes can select one and use.
Key point of the present invention: change the mode of closing and opening user GPRS function among the HLR; In SGSN, revise the cause value that the user who does not possess the gprs service authority adheres to the request refusal.
PS ATTACH flow process:
1) user initiates to adhere to request: if the user does not have legal P-TMSI, the user can be with IMSI; If the user has legal P-TMSI, the user should use the Routing Area Identifier of P-TMSI and pairing, if having P-TMSI signature simultaneously, also should be with.
2) if the user uses P-TMSI to adhere to, and adhered to from last time and to have changed SGSN, new SGSN should send the identification request to old SGSN, with the P-TMSI that goes up the user and corresponding Routing Area Identifier and old P-TMSI signature.Old SGSN responds identification response message, comprises user's IMSI and authentication collection.
3) if the user is unknown at old SGSN, new SGSN should initiate the identification request and give the user, identity type indication IMSI.The user should report that the IMSI of oneself gives SGSN.
4) if user's MM Context does not exist at network side, authentication process is necessary.
5) if the SGSN number changes after separating last time, or adhere to user's the first time, SGSN should notify HLR (position renewal).
SGSN sends a UpdateLocation message (having SGSN number, SGSN address, IMSI) and gives HLR;
It is Update Procedure that HLR transmission Cancel Location (having IMSI, cancellation type) message puts the cancellation type for old SGSN simultaneously;
6) HLR sends and inserts user contracting data message (having IMSI, GPRS subscription data) to new SGSN;
7) if all subscription data inspections are passed through, SGSN constructs the MM context for the user, responds HLR simultaneously and inserts subscription data acknowledge message (having IMSI).
Explanation of nouns:
APNID:Access Point Name ID, i.e. the APN sign of the signatory customization of user
GPRS:General Packet Radio Service, the wireless universal packet service
HLR:Home Location Register attaching position register
PDP:Packet Data Protocol packet data protocol
SGSN:Service GPRS Support Node Serving GPRS Support Node
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
