Step 101: call controller receives the call protection business request information from terminal called, and described call protection business request information comprises: call protection is professional to be opened sign and effective time.
Step 102: call controller receives the calling sign indicating number from calling terminal.Described calling sign indicating number comprises to be called out the code generator sign and calls out first dynamic coding of code generator according to described effective time and the generation of dynamic coding algorithm.
Step 103: call controller is according to described effective time and described dynamic coding algorithm generating second dynamic coding.
Step 104: call controller judges whether described first dynamic coding and described second dynamic coding mate, if, execution in step 105, otherwise, execution in step 107.
Step 105: call controller obtains the terminal called Subscriber Number according to the terminal called Subscriber Number and the corresponding relation of calling out the code generator sign of described calling code generator sign and storage.After step 105, execution in step 106.
Step 106: call controller sends the terminal called Subscriber Number to mobile switching centre's (Mobile Switching Center is called for short MSC), so that MSC connects calling terminal and terminal called.
Step 107: call controller sends wrong Indication message to MSC.
In the embodiment of the invention one, calling terminal adopts the calling sign indicating number relevant with effective time to call out terminal called, according to effective time this callings sign indicating number being verified, verify by the time connection calling terminal and terminal called.Because the calling sign indicating number that is used to call out is relevant with effective time; therefore; calling out sign indicating number changes along with the variation of effective time; a calling sign indicating number is only effective in one period effective time; when surpassing this effective time, this callings sign indicating number can not be verified by, therefore can't get in touch with the user of this terminal called of use; thereby hidden the mobile phone users number, protected the mobile phone users privacy.
Fig. 2 is the flow chart of the method for calling of the embodiment of the invention two.In the embodiment of the invention two, being example with a concrete application scenarios is illustrated the detailed process of this method, in this scene, use the user of terminal called to go out to handle affairs, when he after parking in the garage, for other people can get in touch with themselves when generation scratch accident maybe needs to shift vehicle, need stay the contact method of oneself.With above-mentioned scene is example, and as shown in Figure 2, this method comprises following process.
Step 201: call controller storage terminal called Subscriber Number and the corresponding relation of calling out the code generator sign.
In this step, the user of use terminal called needed in advance terminal called and calling code generator to be bound before needs use the embodiment of the invention two described method of callings protections self privacy.A better embodiment of the concrete grammar of binding is: at call controller storage terminal called Subscriber Number and the corresponding relation of calling out the code generator sign.Wherein, terminal called can have the terminal of communication function for mobile phone etc. arbitrarily, and the terminal called Subscriber Number can be phone number etc.; Call out the code generator sign and can call out sequence number or other any type of identify label (Identity is called for short ID) of code generator for this.
Step 202: terminal called sends the call protection business request information to MSC.
In this step, when the user who uses terminal called need use call protection professional, open and call out code generator, and send the call protection business request information to MSC by terminal called also for it is provided with effective time.Wherein, the call protection business request information comprises: call protection is professional to be opened sign and effective time.Particularly, terminal called can adopt to default call protection service access code and send way of short messages, sends this call protection business request information.A kind of preferred implementation is, note sends with set form, and for example: the professional unlatching of call protection is designated " KSSY ", and be 2 hours effective time, then according to fixed format sends note " KSSY 2H ".For example; use the user of terminal called to go out to handle affairs; need adopt the embodiment of the invention two described method of callings to hide the mobile terminal user number of self when parking; then this user sends the call protection business request information by terminal called to MSC, uses the embodiment of the invention two described method of callings to hide the mobile terminal user number of self by this message request.In this step, can set effective time according to the user's who uses terminal called actual needs, for example can be set at 10 minutes, 1 hour or 1 day.For example, use the user of terminal called early beginning to park at 8 o'clock, expectation need be 2 hours the time of parking, and then be that morning 8 was up to early 10 o'clock effective time.
Step 203:MSC is to call controller forwarded call protection business request information.
In this step, MSC receives the call protection business request information that terminal called sends in the step 202, and this call protection business request information is forwarded to call controller.
Step 204: call controller receives the call protection business request information from terminal called.
In this step, call controller receives the call protection business request information from terminal called that MSC transmits.This call protection business request information comprises: call protection is professional to be opened sign and effective time.After call controller receives this message, know that promptly this terminal called need use the embodiment of the invention two described method of callings to hide the mobile terminal user number.
Step 205: call out code generator and obtain described effective time and generate the calling sign indicating number according to described effective time, described dynamic coding algorithm and calling code generator sign.
In this step, in calling out code generator, set in advance the dynamic coding algorithm.At first, call out code generator according to described effective time and default time marking strategy, the acquisition time sign.Then, call out code generator and generate first dynamic coding according to described time marking and described dynamic coding algorithm.At last, call out the code generator combination and call out code generator sign and described first dynamic coding, generate and call out sign indicating number, this is called out sign indicating number and forms by calling out code generator sign and above-mentioned first dynamic coding.
Step 206: calling terminal sends call request message to MSC.
In this step, comprise in the call request message: default call protection service access code and described calling sign indicating number.The user who uses terminal called stays the remarkable position of vehicle with calling out calling sign indicating number that code generator generates after parking, leave parking place then and handle affairs.Particularly, the user of terminal called can be positioned over the call controller that is provided with screen in the vehicle, should call out sign indicating number by the screen display of this call controller.If the scratch accident takes place afterwards or other people need the user of this use terminal called to shift vehicle; need use the user of terminal called to get in touch with this; this moment, other people can know that the user's of this use terminal called contact method is this calling sign indicating number; thereby other people send the call protection service access code and should call out sign indicating number to MSC by calling terminal; in order to call out this terminal called; particularly; a kind of preferred implementation of step 206 is; calling terminal connects MSC by place calls protection service access code; MSC returns voice suggestion to calling terminal; then, calling terminal is according to this voice suggestion incoming call sign indicating number.
Step 207:MSC call identifying protection service access code sends the calling sign indicating number to call controller.
Step 208: call controller receives the calling sign indicating number from calling terminal.
In this step, particularly, call controller is by the calling sign indicating number of MSC reception from calling terminal.This calling sign indicating number comprises to be called out the code generator sign and calls out first dynamic coding of code generator according to effective time and the generation of dynamic coding algorithm.
Step 209: call controller is according to described effective time and described dynamic coding algorithm generating second dynamic coding.
In this step, the dynamic coding algorithm is set in call controller in advance, this dynamic coding algorithm is identical with the above-mentioned dynamic coding that is provided with in calling out code generator.
Step 210: call controller judges whether described first dynamic coding and described second dynamic coding mate, if, execution in step 211, otherwise, execution in step 213.
In this step, second dynamic coding is that call controller is according to generating with the default dynamic coding identical with calling out code generator the effective time that receives from terminal called.Therefore, if first dynamic coding that receives also is to adopt generate identical effective time, then second dynamic coding should be identical with first dynamic coding, judges that second dynamic coding should be complementary with first dynamic coding.If first dynamic coding that receives is to adopt the time that surpasses the term of validity to generate, perhaps, be any other code that adopts other coded system to generate, then second dynamic coding should be different with first dynamic coding, judge that second dynamic coding should not match with first dynamic coding.
Step 211: call controller obtains the terminal called Subscriber Number according to the terminal called Subscriber Number and the corresponding relation of calling out the code generator sign of described calling code generator sign and storage.After step 211, execution in step 212.
Step 212: call controller sends the terminal called Subscriber Number to MSC, so that described MSC connects calling terminal and terminal called.
In this step, call controller gets access to after the terminal called Subscriber Number, sends it to the MSC in the existing communication network, so that MSC connects calling terminal and terminal called according to this terminal called Subscriber Number.Wherein, this call controller can be positioned at existing communication network, as a node in the existing communication network; Also can be positioned at the MSC of existing communication network, as a module that is integrated in the MSC; Can also be positioned at outside the existing communication network, be independent of existing communication network, be arranged on separately between terminal and the existing communication network.
Step 213: call controller sends wrong Indication message to MSC.
In this step, call controller sends wrong Indication message to MSC, thereby makes MSC return miscue message to calling terminal, and calling terminal can't be connected with terminal called.
Further; after step 204 is carried out; above-mentioned steps 205 is to the implementation of step 213 or after the step 213; can also carry out following steps simultaneously: call controller judges whether the current time belongs to described effective time; if; continue to carry out subsequent step, otherwise call controller cuts out the call protection business of terminal called correspondence.Further, after call controller cuts out the call protection business of terminal called correspondence, can also send the call protection business to this terminal called and close prompting message.A kind of preferred implementation is, this step step 204 to carry out simultaneously between the step 207, in this step, be judged as be after, continue to carry out above-mentioned steps 208.
In the embodiment of the invention two, call out code generator and generate first dynamic coding according to time marking of determining effective time and default dynamic coding algorithm, calling terminal adopts by calling out the calling sign indicating number calling terminal called that the code generator sign and first dynamic coding are formed, call controller according to the time marking of determining the effective time that receives from terminal called with call out the identical dynamic coding algorithm of code generator with this, first dynamic coding in this calling sign indicating number is verified, when checking is passed through, obtain the terminal called Subscriber Number by terminal called Subscriber Number of calling out the calling code generator sign in the sign indicating number and storing in advance and the corresponding relation of calling out the code generator sign, return the terminal called Subscriber Number to MSC, so that MSC connects calling terminal and terminal called.Because it is relevant with the dynamic coding algorithm with effective time to be used to call out the calling sign indicating number of terminal called, therefore, calling out sign indicating number changes along with the variation of time, only in effective time and the calling sign indicating number that has adopted default dynamic coding algorithm to generate just can be verified success, calling terminal could be connected with terminal called.When calling out sign indicating number above effective time; perhaps calling out sign indicating number is not when adopting default dynamic coding algorithm to generate, this callings yard all can not be verified by, calling terminal can't be connected with terminal called; thereby hidden the mobile phone users number, protected the mobile phone users privacy.
