Embodiment two

Please refer to Fig. 2, it shows the method flow diagram of the network limits method that the embodiment of the invention two provides, this network limits method can be used for comprising the communication system of terminal and base station, and connect by wireless network between this terminal in communication system and base station; As the preferred embodiment of above-described embodiment, the network that the network that the present embodiment uses with terminal request and base station provide is the network under the heterogeneous networks pattern that provides of same operator, is example thereby carry out network limits, and this network limits method can comprise:

Step 201, terminal send authentication information to the base station;

The present embodiment take terminal be multi mode terminal as example, in the process of multi mode terminal work, the network service that provides in order to get access to the base station, multi mode terminal can send authentication information to the base station.Concrete, authentication information can comprise the IMSI(International Mobile Subscriber Identification Number of terminal, international mobile subscriber identity), certainly, when specific implementation, authentication information can also comprise other information of terminal, and the present embodiment is not done restriction to this.

Step 202, the authentication information that the base station receiving terminal sends;

The base station receives the authentication information that multi mode terminal sends accordingly.

Open an account under the network schemer whether step 203, base station provide in the base station according to the authentication information sense terminals;

Because multi mode terminal can be supported two kinds or two or more network schemers, and open an account under possible a kind of or certain several pattern therein of the SIM/USIM card that multi mode terminal uses, and the network schemer that provides when the base station be the SIM/USIM card of multi mode terminal do not open an account network schemer the time, the access of multi mode terminal will be refused in the base station, namely do not allow multi mode terminal to use network under the network schemer that the base station provides yet, so after the base station received the authentication information that multi mode terminal sends, the base station can be detected under the network schemer whether multi mode terminal provide in the base station according to authentication information and open an account.

Concrete, because the SIM/USIM that multi mode terminal uses is stuck in when opening an account under certain network schemer, operator can store the IMSI information of SIM/USIM card, so the step of opening an account under the network schemer whether multi mode terminal provide in the base station is detected in the base station according to authentication information, can comprise: the identical IMSI of IMSI in the authentication information that whether exists with the multi mode terminal transmission is detected in the base station in the database that prestores.Certainly, can also adopt other method to detect when specific implementation, the present embodiment is not done restriction to this.

Step 204, whether the base station is identical with the public land mobile network sign of base station according to the public land mobile network sign of authentication information sense terminals;

For the corresponding operator of SIM/USIM card of knowing the current use of multi mode terminal whether identical with the corresponding operator of network service that the base station provides, thereby judge the different network schemer whether network schemer that network of network pattern that the multi mode terminal current request uses and base station provide is provided by same operator, the base station can also be according to the PLMN(Public Land Mobile Network of authentication information sense terminals, public land mobile network) whether identical with the PLMN of base station.

Concrete, the base station is after receiving the authentication information that multi mode terminal sends, and the base station obtains the PLMN of multi mode terminal in can the IMSI from authentication information.Wherein, IMSI can comprise MCC(Mobile Country Code, Mobile Country Code MCC), MNC(Mobile Network Code, Mobile Network Code) and MSIN(Mobile Subscriber Identification Number, identification number of mobile subscriber), and PLMN can comprise MCC and MNC, so the PLMN of multi mode terminal can be read in the base station from IMSI.After the base station read the PLMN of multi mode terminal, whether the PLMN that multi mode terminal can be detected in the base station was identical with the PLMN of base station.

What need supplementary notes a bit is, when specific implementation, the base station can first execution in step 203 rear execution in step 204, also can first execution in step 204 and then execution in step 203, carried out to the multimode mobile phone as long as send feedback information in the base station, the present embodiment is not done restriction to its sequencing;

Need supplementary notes on the other hand, when specific implementation, the network that uses the base station to provide can be attempted asking in the base station for the terminal of telling periphery, the form transmitting system information of broadcast can periodically be passed through in the base station, the PLMN that comprises the base station in the system information, so in the present embodiment, after multi mode terminal receives system information, whether multi mode terminal can also identical with the PLMN of base station according to the PLMN of the detection of the PLMN in system information multi mode terminal, and send the detection result to the base station, base station this moment execution in step 204 not, but sending feedback information to the multimode mobile phone according to the testing result of the testing result that receives and step 203, the present embodiment is not done restriction to this.

Step 205, the base station sends feedback information to terminal according to testing result;

After the step of base station execution of step 203 and step 204, the base station can send feedback information to the multimode mobile phone according to the testing result of step 203 and step 204.Wherein, testing result can comprise open an account under the network schemer that multi mode terminal not do not provide in the base station and the PLMN of the PLMN of multi mode terminal and base station is identical, multi mode terminal provides in the base station network schemer under open an account and the PLMN of the PLMN of multi mode terminal and base station is identical and multi mode terminal less than under the network schemer that the base station provides, not opening an account and in different any of the PLMN of the PLMN of multi mode terminal and base station.

Concrete, because when the network under the network schemer that refusal multi mode terminal use base station, base station provides, the base station can send feedback information to the multimode mobile phone by the mode that sends the Reason For Denial value; So in the present embodiment, when testing result comprises that multi mode terminal is not opened an account and the PLMN of the PLMN of multi mode terminal and base station when identical under the network schemer that the base station provides, the base station can send is scheduled to the Reason For Denial value to the multimode mobile phone.Wherein, predetermined Reason For Denial value is newly-increased cause value in the corresponding communication protocol of network schemer that provides of base station.Such as, the network schemer that the base station provides be the LTE network schemer and this moment base station refusal multi mode terminal, then the base station can send Reason For Denial value newly-increased among communication protocol 3GPP24.301 corresponding to LTE to the multimode mobile phone; The network schemer that the base station provides is WCDMA network schemer and this moment during base station refusal multi mode terminal, and the base station can send Reason For Denial value newly-increased among communication protocol 3GPP24.008 corresponding to WCDMA to the multimode mobile phone.

Such as, multi mode terminal is supported GSM and two kinds of network schemers of LTE, the SIM/USIM card of the current use of multi mode terminal is mobile 2G card, only under the network schemer of GSM, open an account, and under the LTE network schemer, do not open an account, then when multi mode terminal request when to use mobile 4G network also be network under the LTE network schemer, provide the base station of mobile LTE network schemer can send Reason For Denial value #112 newly-increased among the 3GPP24.301 to the multimode mobile phone; Similarly, when multi mode terminal is supported GSM and two kinds of network schemers of WCDMA, the SIM/USIM card that multi mode terminal uses is the 2G card of UNICOM, only under the WCDMA network schemer, do not open an account opening an account under the GSM network schemer, then when multi mode terminal request when to use the 3G network of UNICOM also be network under the WCDMA network schemer, provide the base station of UNICOM's 3G network pattern can send Reason For Denial value #112 newly-increased among the 3GPP24.008 to the multimode mobile phone.

Under the network schemer that testing result provides in the base station for multi mode terminal, open an account, and the PLMN of multi mode terminal is identical with the PLMN of base station, then this moment, the base station can send confirmation to multi mode terminal, thereby so that the network under the network schemer that multi mode terminal use base station provides, the present embodiment repeats no more this;

Under the network schemer that testing result does not provide in the base station for multi mode terminal, open an account, and the PLMN of multi mode terminal is different from the PLMN of base station, be illustrated as then that multi mode terminal provides the operator of service this moment and be not same operator for the base station provides the operator of service, so the base station can adopt existing Reason For Denial value to be sent to terminal as feedback information, the present embodiment does not repeat them here.

What need supplementary notes is, the present embodiment is just to use #112 Reason For Denial value as example, when specific implementation, can also use any in the idle cause value in the communication protocol, and the Reason For Denial value of using among 3GPP24.301 and the 3GPP24.008 can be the same or different, and the present embodiment is not done restriction to this;

Step 206, terminal receives the feedback information that the base station sends;

Accordingly, multi mode terminal can receive the feedback information that the base station sends.

Step 207, if the feedback information that receives represents that terminal is not opened an account and the public land mobile network sign of terminal is identical with the public land mobile network sign of base station under network schemer, then limiting terminal asks to use the network under the network schemer again;

Under feedback information that multi mode terminal receives represents network schemer that multi mode terminal do not provide in the base station, open an account and the PLMN of multi mode terminal identical with the PLMN of base station, illustrate that then the operator that SIM/USIM card that multi mode terminal uses at this moment and base station provide network is same operator, open an account under the network schemer that just the SIM/USIM card does not provide in the base station, so this moment, multi mode terminal can the limit multimode mobile phone asks to use the network under the network schemer that the base station provides again.

Such as, the feedback information that multi mode terminal receives is #112, then multi mode terminal can know open an account under the network schemer that SIM/USIM card that multi mode terminal uses do not provide in the base station and the PLMN of SIM/USIM card identical with the PLMN of base station, so multi mode terminal will not reattempt the network of asking under the network schemer that the base station provides.

If the feedback information that multi mode terminal receives represents to open an account under the network schemer that multi mode terminal provides in the base station and the PLMN of multi mode terminal is identical with the PLMN of base station, then this moment, multi mode terminal can reside in the residential quarter that the base station covers, the network service that uses the base station to provide;

If the feedback information that multi mode terminal receives represents that multi mode terminal is not opened an account and the PLMN of multi mode terminal is different from the PLMN of base station under network schemer, then at this moment, multi mode terminal can continue to other base station transmission requests, thereby the network service that request uses other base station to provide, this and existing processing method are similar, and the present embodiment does not repeat them here.

Step 208 receives the predetermined trigger signal;

After multi mode terminal limit multimode mobile phone asked to use network under the network schemer that the base station provides again, multi mode terminal can receive the predetermined trigger signal.Wherein, the predetermined trigger signal can comprise the triggering signal of restarting multi mode terminal or network schemer that multi mode terminal is provided in the base station of refusing before this multi mode terminal under the triggering signal of opening an account.Concrete, because when the user opens an account multi mode terminal under a certain network schemer, multi mode terminal can be informed by the form of note or mail in the base station, so multi mode terminal can receive the triggering signal that multi mode terminal is opened an account accordingly under a certain network schemer.

Step 209 after receiving the predetermined trigger signal, is removed the restriction of terminal being asked to use again the network under the network schemer.

After multi mode terminal received the predetermined trigger signal, multi mode terminal can be removed the restriction of multi mode terminal being asked to use again the network under the network schemer.

Concrete, because after multi mode terminal is restarted, the SIM/USIM card that multi mode terminal uses may be replaced, SIM/USIM card in the multi mode terminal after also namely restarting may be the SIM/USIM card of opening an account under the network schemer that provides in the base station of refusing before this multi mode terminal, and this moment, the base station can allow the multi mode terminal request to use network under the network schemer, so after multi mode terminal receives the triggering signal of restarting multi mode terminal, multi mode terminal will be removed the restriction of multi mode terminal being asked to use again the network under the network schemer; Simultaneously, be in the confined process at multi mode terminal, the user may arrive operator and locate SIM/USIM with multi mode terminal and be stuck under the network schemer that the base station provides and open an account, and the multi mode terminal after opening an account can use the network under the network schemer that the base station provides, so receive after the triggering signal that multi mode terminal is opened an account under network schemer at multi mode terminal, multi mode terminal will be removed the restriction of multi mode terminal being asked to use again the network under the network schemer.

Need to prove, the present embodiment is just take above-mentioned predetermined trigger signal as example, when specific implementation, the user can arrange multi mode terminal according to the user demand of self, thereby so that multi mode terminal is also removed the restriction of multi mode terminal being asked to use again the network under the network schemer after the triggering signal that receives user's setting, the present embodiment is not done restriction to this.

Step 301, terminal send authentication information to the base station;

The present embodiment still is example take terminal as multi mode terminal.The network service that provides in order to get access to the base station, multi mode terminal can send authentication information to the base station.Concrete, authentication information can comprise the IMSI of terminal, and certainly, when specific implementation, authentication information can also comprise other information of terminal, and the present embodiment is not done restriction to this.

Step 302, the authentication information that the base station receiving terminal sends;

Open an account under the network schemer whether step 303, base station provide in the base station according to the authentication information sense terminals;

Need to prove, the concrete detecting step of base station is identical with detecting step in the step 203 of embodiment two, specifically please refer to step 203, and the present embodiment repeats no more this.

Step 304, the base station sends feedback information to terminal according to testing result;

After the detection of step 303 was carried out in the base station, the base station can send feedback information to terminal according to testing result.

Concrete, because during the network under the network schemer that refusal multi mode terminal use base station, base station provides, multi mode terminal can be refused by the mode that sends the Reason For Denial value in the base station, so in the present embodiment, under the network schemer that the testing result of base station does not provide in the base station for multi mode terminal, open an account, thereby when needing the refusal multi mode terminal, the base station can send predetermined Reason For Denial value to the multimode mobile phone.Wherein, predetermined Reason For Denial value is newly-increased cause value in the corresponding communication protocol of network schemer that provides of base station.Such as, the network schemer that the base station provides is LTE, and the base station detects multi mode terminal and does not open an account under the network schemer of LTE, and then the base station can send Reason For Denial value newly-increased among communication protocol 3GPP24.301 corresponding to LTE to the multimode mobile phone; The network schemer that provides when the base station is WCDMA, and the base station detects multi mode terminal and do not open an account under the network schemer of WCDMA, and then the base station can send Reason For Denial value newly-increased among communication protocol 3GPP24.008 corresponding to WCDMA to the multimode mobile phone.

Such as, multi mode terminal is supported GSM and two kinds of network schemers of LTE, the SIM/USIM card of the current use of multi mode terminal is only to open an account under the GSM network schemer and the card of not opening an account under the LTE network schemer, then when the network under the multi mode terminal request use LTE network schemer, the base station can send Reason For Denial value #112 newly-increased among the 3GPP24.301 to the multimode mobile phone; Similarly, when multi mode terminal is supported GSM and two kinds of network schemers of WCDMA, the SIM/USIM card that multi mode terminal uses is only to open an account under the GSM network schemer and the card of not opening an account under the WCDMA network schemer, then when the network under the multi mode terminal request use WCDMA network schemer, the base station can send Reason For Denial value #112 newly-increased among the 3GPP24.008 to the multimode mobile phone.

Open an account under the network schemer that the testing result of base station provides in the base station for multi mode terminal, then the base station can send confirmation to the multimode mobile phone, and the present embodiment does not repeat them here.

What need supplementary notes a bit is, the present embodiment is just to use #112 Reason For Denial value as example, when specific implementation, can also use any in the idle cause value in the communication protocol, and the Reason For Denial value of using among 3GPP24.301 and the 3GPP24.008 can be the same or different, and the present embodiment is not done restriction to this;

Need supplementary notes on the other hand, owing to being whether detect the PLMN of multi mode terminal by multi mode terminal identical with the PLMN of base station in the present embodiment, so the base station does not consider whether the PLMN of multi mode terminal is identical with the PLMN of base station when sending feedback information in the base station, just send feedback information as long as detecting opens an account under the network schemer that multi mode terminal do not provide in the base station, the present embodiment does not repeat them here.

Step 305, terminal receives the feedback information that the base station sends;

Step 306, whether the public land mobile network sign of terminal sense terminals is identical with the public land mobile network sign of the base station that gets access to;

For the corresponding operator of SIM/USIM card of knowing the current use of multi mode terminal whether identical with the corresponding operator of network service that the base station provides, thereby judge the different network schemer whether network schemer that network of network pattern that the multi mode terminal current request uses and base station provide is provided by same operator, when feedback information that multi mode terminal receives represented that multi mode terminal is opened an account under the network schemer that the base station provides, whether the PLMN that multi mode terminal can also detect multi mode terminal was identical with the PLMN of the base station that gets access to.Wherein, the multi mode terminal step of obtaining the PLMN of base station can comprise:

The first, receive the system information that the base station sends;

The network that uses the base station to provide can be attempted asking in the base station for the terminal of telling periphery, the base station can transmitting system information to the multimode mobile phone, corresponding, multi mode terminal can receive the system information that the base station sends.Wherein, carry the PLMN of base station in the system information.Concrete, the base station can be periodically by the form transmitting system information of broadcast, and corresponding, multi mode terminal can periodically receive the system information that the base station sends.

The second, from system information, read the PLMN of base station.

After multi mode terminal received the system information of base station transmission, multi mode terminal can read the PLMN of base station from system information.

Step 307, if the testing result of terminal represents terminal less than opening an account under the network schemer that provides in the base station for feedback information identical and that receive, then the terminal limitations terminal asks to use the network under the network schemer again;

If it is identical with the PLMN of base station that multi mode terminal detects the PLMN of multi mode terminal, and the feedback information that receives represents multi mode terminal less than opening an account under the network schemer that provides in the base station, illustrate that then the current corresponding operator of SIM/USIM card that uses of multi mode terminal is that same operator opens an account under the network schemer that do not provide in the base station of the SIM/USIM card that uses of multi mode terminal with the operator of network is provided as the base station, so multi mode terminal can the limit multimode mobile phone be asked the network under the network schemer that the base station provides again.

Need to prove, when reality realizes, in order to reduce the computation complexity of multi mode terminal, just step 306 can represent that at the feedback information that multi mode terminal receives multi mode terminal not carry out when opening an account under the network schemer that the base station provides, the present embodiment does not repeat them here.

Step 308 receives the predetermined trigger signal;

After multi mode terminal limit multimode mobile phone asked to use network under the network schemer that the base station provides again, multi mode terminal can receive the predetermined trigger signal.Wherein, the predetermined trigger signal can comprise the triggering signal of restarting multi mode terminal or network schemer that multi mode terminal is provided in the base station of refusing before this multi mode terminal under the triggering signal of opening an account.

Step 309 after receiving the predetermined trigger signal, is removed the restriction of terminal being asked to use again the network under the network schemer.

After multi mode terminal received the predetermined trigger signal, multi mode terminal can be removed the restriction of multi mode terminal being asked to use again the network under the network schemer.Step 209 among this step and the embodiment two is similar, specifically please refer to step 209, and the present embodiment does not repeat them here.
