Abstract
This invention provides a method for indicating service state to terminals including: a terminal reads the attribute information in a current user ID card and judges if the attribute information of the current ID card of the user is the same with that of one user ID card in all user ID cards kept in an internal storage of said terminal to determine if the current user ID card carries out service process or signaling process in the network system by other access mode or other terminals in the time when it is used in said terminal last time and the terminal this time to decide to indicate the service state in the stored attribute information to users, or decides to enquire the service state corresponding to the current user ID card from the network system to indicate the service state to the user.
Description
Technical field
The present invention relates to the communication technology, relate in particular to the technology of service station indication of terminal.
Background technology
In communication services such as existing for example unconditional call forwarding, mobile phone users is after activating the unconditional call forwarding business, all are that called Circuit Service calling all directly arrives the target terminal that the unconditional call forwarding business sets with this portable terminal, portable terminal can't be received these callings, and can't know these callings have taken place.If activating the user under the situation of unconditional call forwarding business, portable terminal can not remind the present residing unconditional call forwarding state of user in some way, then the user may not remind because obtain, and not in good time cancellation unconditional call forwarding business, the Circuit Service that causes not receiving described portable terminal is called out, and can bring unnecessary loss to the user like this.
Generation for fear of above-mentioned situation, China's Telecommunication's ANSI is at GSM/GPRS (GlobalSystem for Mobile communications/General Packet Radio Service, global mobile communication system/general grouping wireless service) in the industry standard that terminal technology requires, requires portable terminal to be in user's unconditional call forwarding business under the situation of state of activation and can correctly point out current unconditional call forwarding state.
Because 3GPP (Third Generation Partnership Project, the 3rd generation cooperative programme) (Release 4 for R4, the 4th edition) before SIM-ME (Subscriber Identity Module-MobileEquipment, Subscriber Identity Module-mobile device) interface specification 51.011 (V4.1.0) and 11.11 and USIM (Universal Subscriber Identity Module, universal subscriber identity module) using standard 31.102 (V4.0.0) is not at SIM (Subscriber Identity Module, Subscriber Identity Module) definition is used for preserving the file of user's unconditional call forwarding state in card or the usim card, so, according to these standards a large amount of SIM card that manufactures and designs and UICC (the UniversalIntegrated Circuit Card that comprises the USIM application, Universal Integrated Circuit Card) unconditional call forwarding state that all can not recording user, wherein, the UICC that comprises the USIM application is usim card, in the present invention, SIM card and usim card are referred to as the user ID card.The SIM-ME interface specification 51.011 (V4.1.0) that 3GPP R4 is later and USIM using standard 31.102 (V4.0.0) are though increased the file EF that definition is used for preserving user's calling transfer state
CFIS(Elementary File of Call Forwarding IndicationStatus, the constituent instruments that comprise the calling transfer indicating status), but because this document is an optional file, so, still may be according to a part of SIM card and usim card that these standards are produced because of not supporting EF
CFISFile and unconditional call forwarding state that can not recording user.
Because SIM card inserts the gsm system except being used for the GSM terminal, can also be used for 3G (ThirdGeneration, 3G (Third Generation) Moblie) terminal inserts the 3G system, the SIM card of unconditional call forwarding state that therefore, can not recording user not only can influence user's gsm service, also can influence the 3G business.Equally, according to a large amount of 2G (Second Generation, second generation mobile communication) of the design of the Version Spec before the 3GPP R4 or 3G terminal owing to can not read or upgrade EF in SIM card and the usim card
CFISFile, and can't pass through EF
CFISFile correctly writes down and indicates user's unconditional call forwarding state.A part also may be because of not supporting EF according to the 2G or the 3G terminal of the later Version Spec design of 3GPP R4
CFISFile can not pass through EF
CFISFile correctly writes down and indicates user's unconditional call forwarding state.2G or 3G terminal according to the later Version Spec design of 3GPP R4 may not supported EF because of the SIM or the usim card that use yet
CFISFile and can not pass through EF
CFISFile correctly writes down and indicates user's unconditional call forwarding state.
Because a large amount of EF that do not support
CFISSIM card and the existence of usim card, and can not visit and upgrade EF
CFISThe 2G of file and the existence of 3G terminal, cause portable terminal can not correctly indicate the unconditional call forwarding state in some cases, make the mobile subscriber wish that the demand of understanding the unconditional call forwarding state by the correct prompting of portable terminal is difficult to be met.
In order to address the above problem, the multiple technologies scheme has appearred in the art, wherein a kind of scheme as shown in Figure 1, Fig. 1 is at every turn the start shooting flow chart of method of time indication unconditional call forwarding state of portable terminal.
In step S101, portable terminal is at for example NVRAM (Non-Volatile Random AccessMemory, nonvolatile random access memory) reserved storage space in the internal storage, be used for preserving ICC ID (Integrated Circuit (s) the Card Identifier in SIM card or the usim card, integrated circuit card sign) or IMSI (International Mobile Subscriber Identity, IMSI International Mobile Subscriber Identity) and user's unconditional call forwarding state information.
Enter step S102, during mobile terminal-opening, whether identical by the user ID of preserving in the more described portable terminal with the user ID of current SIM card or usim card, whether the previous user who judges the described portable terminal of use is identical with the active user, if the user ID of preserving in the described portable terminal is identical with the user ID of current SIM card or usim card, then described portable terminal after residing network not initiatively to network inquiry user's unconditional call forwarding state, enter step S105, otherwise, enter step S103.
In step S103, described portable terminal is removed the user ID and the unconditional call forwarding state information of preserving in the internal storage, and preserves active user's sign.
Enter step S104 behind the completing steps S103, described portable terminal is after residing network, immediately on one's own initiative to network inquiry user's unconditional call forwarding state, and the described unconditional call forwarding state that inquires is kept in the internal storage, this process can the position upgrade or Routing Area Update success back or follow-up Circuit Service calling procedure in carry out.
Enter step S105 behind the completing steps S104, described portable terminal enters holding state and reads the unconditional call forwarding state information of preserving in the internal storage.
Enter step S106, judge whether the unconditional call forwarding state that reads is state of activation, if, enter step S107, otherwise, step S108 entered.
In step S107, it is state of activation that described portable terminal is indicated the unconditional call forwarding state by man-machine interface to the user.
In step S108, to indicate the unconditional call forwarding state be unactivated state to described portable terminal or the unconditional call forwarding state is not carried out any indication to the user by man-machine interface.
Please refer to the step S102 of technique scheme, if terminal determines to use the previous user of portable terminal identical with the active user, portable terminal can be not initiatively to network inquiry user's unconditional call forwarding state, but directly read the unconditional call forwarding state information of preserving in the internal storage, in other words, the active user's that thinks of Ci Shi portable terminal unconditional call forwarding state is the unconditional call forwarding state of preserving in the internal storage.In actual applications, the mobile subscriber might preceding once use described portable terminal after, activate by other terminal or under other access module again or cancelled the unconditional call forwarding business, and described portable terminal preceding once use described mobile subscriber's SIM or usim card after, do not use other SIM card or usim card, in this case, when described mobile subscriber reuses described portable terminal, because described portable terminal detects active user's tag card when start identical with previous user ID card, so, described portable terminal can be not initiatively after start the unconditional call forwarding state to the network inquiry user, but directly whether indicate by man-machine interface according to the calling transfer state information decision of preserving in the portable terminal, and the calling transfer state that this moment, described portable terminal was preserved may be inconsistent with actual calling transfer state, and then indicated wrong calling transfer state to the user, and, if described portable terminal uses described SIM card or usim card always, then after the user initiatively made a call transfer renewal or inquiry, described portable terminal is the indicating call transfering state correctly.
In addition, when when described mobile terminal-opening, detecting active user's tag card or active user tag card different and being to use first user ID card of described portable terminal with previous user ID card, if described portable terminal just is being shut down after the sign that keeps active user's tag card and before carrying out calling transfer status poll success or is cutting off the power supply, then as long as described portable terminal uses described SIM card or usim card always, during start next time of described portable terminal, identical because of detecting the user ID of preserving in the portable terminal with the user ID of current SIM card or usim card, just no longer to the calling transfer state of network inquiry active user tag card, the user initiatively make a call shift to upgrade or inquiry before, described portable terminal is indicating call transfering state correctly all.

The attribute information that method of the present invention need be judged active user's tag card whether be kept at the terminal inner memory in the attribute information of one of them user ID card of all user ID cards identical, determine according to judged result active user's tag card is applied to whether carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the terminal at preceding terminal and this of once being applied to, and then whether decision needs to network system inquiry business state, we can say, the attribute information of judging active user's tag card whether be kept at the terminal inner memory in the identical purpose of attribute information of one of them user ID card of all user ID cards, exactly in order to determine active user's tag card is applied to whether carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the terminal at preceding terminal and this of once being applied to, and may comprise the process that changes service condition in these Business Processing processes or the signaling procedure, thereby the business state information that causes preserving in the terminal may be not correct, in this case, terminal has only the current business state to network inquiry active user tag card, and could guarantee provides correct service condition indication to the user who uses terminal.And in existing method, terminal does not judge active user's tag card is applied to whether carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the terminal at preceding terminal and this of once being applied to, furtherly, under the situation whether terminal of existing method may take place to change at the service condition of not judging the user ID card, the service condition of once preserving before directly using, thereby the accuracy rate of existing method service station indication is lower than method of the present invention.
In the conventional method, terminal is only preserved the user ID and the service condition of a user ID card, if described user ID is stuck between a preceding VAS application-to-terminal service and this VAS application-to-terminal service, also VAS application-to-terminal service of other user ID card is arranged, when then described user ID is stuck in this VAS application-to-terminal service, even described user ID is stuck between a preceding VAS application-to-terminal service and this VAS application-to-terminal service and did not use on other terminal, terminal is as long as find that the user ID of described user ID card is different with the user ID of the user ID card of preservation, just to the described user ID card of network inquiry corresponding service state.And in the method for the invention, terminal can be preserved the attribute information of a plurality of user ID cards, if active user's tag card once was applied in the terminal, may still preserve the attribute information of described user ID card in the terminal, so, even once being applied to described terminal and this before described user ID is stuck in is applied to and has other user ID card also to be applied under the situation of described terminal between the described terminal, described terminal meeting is identical because of the attribute information of one of them user ID card that the attribute information and the terminal of the described user ID card of discovery have been preserved, and need not again to the described user ID card of network inquiry corresponding service state.In addition, in the method for existing some service station indication, terminal the time is not done any judgement just to the state of network inquiry business in start, and in the method for the invention, terminal only at definite active user's tag card preceding when once being applied to terminal and this and being applied in network system, carry out Business Processing process or signaling procedure between the terminal, just to the state of network inquiry business by other terminal or other access module.So method of the present invention can be saved network signaling overhead with respect to existing method.
In addition, in the method for the invention, terminal does not rely on the EF that whether can support for example to write down the unconditional call forwarding business state information in SIM card or the usim card
CFISThe file of record traffic state informations such as file, the state of indicating services correctly just, existing problem when having avoided existing method only according to the content service station indication of the business state information file in the user ID card.
In addition, method of the present invention can and be improved the problem that exists in the existing method with existing method coexistence.When the user ID card of supporting business status information file is applied to not support the terminal of this document, because this terminal is not supported the business state information file in the user ID card, can't upgrade the information in this document, so behind the state of this terminal modifications business, information in the user ID card in the business state information file no longer conforms to actual conditions, when this user ID card was applied to only not adopt the terminal of the inventive method according to business state information file service station indication, this terminal can be indicated the service condition with virtual condition does not conform in the business state information file to the user.If but this user ID card is when being applied to adopt the terminal of the inventive method, terminal can use from network inquiry to service condition upgrade the business state information of the mistake of preserving the business state information file in the user ID card, make this user ID card only be applied to according in the terminal of business state information file service station indication the time, this terminal is service station indication correctly just also again.

KcGPRSIn (constituent instruments that comprise KcGPRS) file, when being applied to the GSM terminal, the user ID card also can be come out by the GSM terminal recognition thereby make the user ID clamping go into Business Processing process or the signaling procedure that 3G network carries out.
Need to prove, can preserve the attribute information of a plurality of user ID cards in the internal storage of terminal, certainly, the attribute information of preserving all should be the attribute information that once was applied in the user ID card in the terminal, what, can decide according to the capacity and the actual needs of internal storage as for the attribute information that needs to preserve a user ID card in the internal storage.If terminal is when preserving the attribute information of active user's designation card, there is not available memory space in the internal storage of terminal, after then deleting a user ID card attribute information of preserving the earliest in the terminal inner memory, preserve the attribute information of active user's designation card again.
Behind the completing steps S201, enter step S202, attribute information by judging active user's tag card whether be kept at the terminal inner memory in certain attribute information identical, determine described active user's tag card is applied to whether carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the described terminal at preceding described terminal and this of once being applied to.Active user's tag card here is to make a comment or criticism to be applied to user ID card in the terminal, if the attribute information of active user's tag card is identical with attribute information in being kept at the terminal inner memory, and the corresponding information content is identical, determine that then active user's tag card is applied to not carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the described terminal at preceding described terminal and this of once being applied to, otherwise, carried out Business Processing process or signaling procedure.Because the attribute information of mentioning in step S201 has a plurality of information, for example user ID, security parameter etc., so must judge to each information in the attribute information, the attribute information that could determine active user's tag card whether be kept at internal storage in attribute information identical, thereby determine further active user's tag card is applied to whether carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the described terminal at preceding described terminal and this of once being applied to.
User ID is the identity symbol of user ID card, when starting up of terminal, need to judge whether active user's tag card was used in terminal, so, when the attribute information of attribute information that compares active user's tag card and described preservation, what at first compare just should be user ID, if user ID exists in internal storage, illustrate that then active user's tag card used really in described terminal, continue relatively other information, if user ID does not exist in internal storage, the service condition of not preserving active user's tag card in the described terminal then is described, terminal need be inquired about described active user's tag card corresponding service state to network system, and the sign and the described service condition that inquires of active user's tag card is kept in the internal storage of described terminal.
If user ID is preserved in internal storage, whether the security parameter that then continues to judge active user's tag card is identical with the security parameter of active user's tag card of preserving in the terminal, if, can determine that active user's tag card is applied to not carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the described terminal at preceding described terminal and this of once being applied to, otherwise, determine that active user's tag card is applied to carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the described terminal at preceding described terminal and this of once being applied to, at this moment, terminal need be inquired about active user's tag card corresponding service state to network system, and upgrades the service condition of preserving in the terminal inner memory with the service condition that inquires.
If security parameter is identical, whether the positional information that then also can further judge active user's tag card is identical with the positional information of active user's tag card of preserving in the terminal, if, can determine further that then active user's tag card is applied to not carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the described terminal at preceding described terminal and this of once being applied to, otherwise, can determine that active user's tag card is applied to carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the described terminal at preceding described terminal and this of once being applied to, terminal need be inquired about described active user's tag card corresponding service state to network system, and upgrades the service condition of preserving in the terminal inner memory with the service condition that inquires.
In actual applications, terminal except that urgent call other any business or during signaling procedure, in order to prevent that disabled user's tag card from inserting, the commercial network system generally all can stick into capable authentication to user ID, SIM card or usim card when authentication according to the length of receiving from network side be the random number of 128 bits generate new security parameter and be kept at SIM card or usim card respective file in.Even do not carry out authentication in certain 3G Business Processing process or the signaling procedure, encryption and KI in the security parameter do not change, but START
CSOr START
PSIn one also can change; Cause the encryption in the security parameter identical even the random number of using when carrying out authentication in certain 3G Business Processing process or the signaling procedure is identical with KI, but with Business Processing process and signaling procedure in the relevant START of number of data blocks that transmits
CSOr START
PSAlso may be different; Cause the encryption in the security parameter identical with KI even the random number of using when carrying out authentication in certain Business Processing process or the signaling procedure is identical, CKSN, the CKSNGPRS of network two sub-distribution, KSI also may be different.Because user's mobility can cause the variation of lane place and Routing Area Identifier in the user ID card, the heavily distribution of Temporary Mobile Subscriber Identity can cause the variation of Temporary Mobile Subscriber Identity in the user ID card in Business Processing process and the signaling procedure, the sub-district of different access technologies is used different Location Area Identitys usually, terminal uses different access technologies to carry out Business Processing process or signaling procedure can cause the lane place in the user ID card and the variation of Routing Area Identifier, so combining position information can reduce the constant harmful effect that brings of security parameter that the randomness because of authentication parameter may cause, judge more accurately user ID be stuck in before once and this use whether carry out certain Business Processing process or signaling procedure between this terminal, wherein, the probability that security parameter is constant is less than 2
-128In sum, when once being applied to described terminal and this before the user ID card and being applied to described terminal, the identical probability of above-mentioned all parameters is much smaller than 2
-128, can ignore, in other words, utilize these parameters, before can identifying user ID basically and being stuck in once and this use any Business Processing process or the signaling procedure that whether carried out between this terminal except that urgent call.Therefore, in the realization of the inventive method, can select for use the combination of the little a part of parameter of recurrence probability in above-mentioned security parameter and the location parameter judge user ID be stuck in before once and this use any Business Processing process or the signaling procedure that whether carried out between this terminal except that urgent call.Positional information comprises circuit domain temporary mark or the packet domain temporary mark that the user is given in the lane place at user place or Routing Area Identifier and network allocation, the reason that causes positional information to change mainly contains two: one, active user's tag card by accessing terminal to network after the lane place or the route district at place variation has taken place, for example user terminal resident in consolidated network the diverse location district or user terminal selecting different access modules inserted different 2G or the 3G networks of Location Area Identification, and carried out location area updating or Routing Area Update process; Two, network in Business Processing process or signaling procedure for the user has distributed new user's temporary mark, as TMSI, P-TMSI or P-TMSI signature.
Need illustrate, very low just because of the each probability that generates identical security parameter during with the network system authentication of active user's tag card, so the step of judgement positional information is inessential, if but increased this step, the technique effect that the present invention is produced would be more obvious.
Behind the completing steps S202, enter step S203, the result definite according to step S202, decision is indicated service condition in the attribute information of preservation to the user, perhaps, decision is indicated the service condition that inquires to the user behind network system inquiry active user tag card corresponding service state.If terminal is determined active user's tag card and is applied to not carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the described terminal at preceding described terminal and this of once being applied to, because during starting up of terminal, active user's tag card and network system have been carried out authentication or data and Signalling exchange have been taken place, security parameter can change, so the security parameter of active user's tag card that terminal is preserved in need the current safety parameter update terminal with active user's tag card, and indicate service condition in the attribute information of preservation to the user.If terminal is determined active user's tag card and is applied to carry out Business Processing process or signaling procedure by other terminal or other access module in network system in time between the described terminal at preceding described terminal and this of once being applied to, terminal is being inquired about active user's tag card corresponding service state to network system, and after the service condition that inquires being kept at the internal storage of terminal, current safety parameter in active user's tag card could be preserved or, indicate the service condition that inquires to the user at last with the security parameter of active user's tag card of having preserved in the current safety parameter update terminal in active user's tag card.
In addition, if attribute information also comprises positional information, terminal is preserved the positional information of the active user's tag card that also needs in the security parameter current location information in active user's tag card preserved or preserved with the renewal of the current location information in active user's tag card in said process.
Need to prove, need be if terminal is judged by user ID, security parameter and the positional information of preserving in comparison user ID card and the terminal after start to the network inquiry service condition, then terminal is before service condition inquiry and preserving successfully, should not preserve security parameter in the user ID card and positional information or with the security parameter in the user ID card and updating location information security parameter and positional information.This be because, if terminal need be to the network inquiry service condition, the service condition that active user's tag card of the current business state of not preserving active user's tag card in the terminal as yet or preservation then is described may not be the current business state, if terminal is just being preserved to the network inquiry service condition and before preserving successfully or is being upgraded security parameter and positional information and be shut down immediately or cut off the power supply, when then described terminal reuses the start of described user ID card, can be because the user ID of preserving in user ID card and the terminal, corresponding security parameter and positional information are all identical, just can be not again to the current business state of network inquiry user ID card correspondence, and directly the possible incorrect service condition of preserving in the terminal is indicated to the user as the current business state of user ID card correspondence.So, in order to guarantee the service condition of terminal to user's indicating correct, need be if terminal is judged when start to the network inquiry service condition, then terminal is before service condition inquiry and preserving successfully, can not preserve security parameter in the user ID card and positional information or the more security parameter and the positional information of correspondence in the new terminal.
In actual applications, terminal can be indicated active user's tag card corresponding service state by man-machine interface, in general, when service condition is state of activation, terminal has suggested in man-machine interface, certainly, terminal can be state of activation or unactivated state at service condition also, carries out different promptings in man-machine interface.
In addition, behind the completing steps S203, terminal is when each activation, cancellation or inquiry business state, and described terminal needs to preserve in described internal storage or renewal active user tag card corresponding service state; After carrying out Business Processing or signaling procedure at every turn, the security parameter that described terminal is preserved in need the current safety parameter update terminal inner memory with active user's tag card; When the updating location information of each user ID card, described terminal is upgraded the positional information of preserving in the described terminal inner memory with the current location information of active user's tag card.
It should be noted that also method of the present invention is applicable to unconditional call forwarding business or call blocking business etc.
