When carrying out switching between standard, also need to determine the network formats of second number, and when the network formats of the network formats of second number and first number is inequality, after the network authentication information setting is the authentication information of second number, the mode of operation of smart card is set to the network formats of the second number correspondence, so that terminal is determined to switch the back network formats and connect network.
Usually all be provided with function corresponding in the smart card and obtain network state, when to get access to network state be the limiting network service or do not have network when service, if the user still uses the number of current standard, the network service nature that obtains is not good, at this moment just can be according to setting in advance, switch to the number of other standard, thereby obtain preferable network service.
Certainly, for making the user further obtain effect network service preferably, can also connect under the network case of successful, carrying out number according to network informations such as country code, wireless access ways switches, make the network formats after switching be complementary, and then obtain network service preferably with the network information that is obtained.
Also can carry out number according to the information of home location of number and switch, make that the number after switching is consistent with the current location of user, can further be convenient to user's use like this.
Further, in order to better meet user's demand, the user can manually carry out standard and switch, and switches on the number of the network formats that the user needs, thereby obtains corresponding service.
Concrete:
Receive under the network formats of first number network state be the limiting network service or do not have network service after, determine to be specially second number that switches to:
When network state is the limiting network service,, determine that second number that switches to is, with the number of the corresponding network formats of country code according to the switching law that sets in advance;
When no network is served, according to the switching law that sets in advance, determine that second number that switches to is, be different from the number of first number according to the definite network formats of priority orders.
Certainly,, also can pass through to receive user's switching command triggering number switching, make that switching is more flexible for further satisfying user's demand.
Switching law is provided with when smart card dispatches from the factory usually, can certainly be provided with according to user's demand and change.
For example, a kind of preferable being set to: can be on 3G or 4G smart card, the switch application of the number of different network formats is set, set up the memory space of number data relevant information for the data of each number, it is the number information memory block, as be provided with GSM (Global System for Mobilecommunication, global system for mobile communications) standard, WCDMA (Wide-band Code DivisionMultiple Access, WCDMA access system) standard, the CDMA2000 standard, TD-SCDMA (Time Division Synchronized Code Division Multiple Access, when the time-division synchronous CDMA system) standard is with certain 4G standard, then can set up 5 memory spaces, and in these 5 memory spaces, store the GSM number data respectively, the WCDMA number data, the CDMA2000 number data, TD-SCDMA number data and 4G number data, difference according to network formats, number data is also different, as GSM standard number information storage area stores KI KI, international mobile subscriber identity IMSI, network authentication data such as short message centre number, 3G number information memory space is number storing authentication five-tuple then, difference according to the 3G network standard, the key element of being stored also may be different, and 4G number information memory block is respective stored 4G number authentication key element then.
For easy to use, a primary number can be set, if the user is longer in time within Chinese territory, then can use the TD-SCDMA number as primary number, when the each power-on reset of terminal, use this primary number to connect network, it is the 3G pattern that the smart card mode of operation is set, terminal is carried out the authentication of mobile phone terminal and 3G network according to the unified authentication process of formulating of International Telecommunication Union, attempt logging in network, certainly, according to actual conditions, other 3G standard number or 2G number, 4G number also can be set as primary number.
The rule that number switches can be set to:
When the success of initial log network, can further obtain the network information of current network, and then select the network formats of coupling more, and switch to corresponding number, the network information of the current network of being obtained can comprise: country code, the employed radio access technology types of current network etc., the type of wireless access technology may be 3G access technology, GSM access technology or LTE (Long Term Evolution, Long Term Evolution) access technology etc.
When triggering switching by radio access technology types, after the logging in network success, obtain radio access technology types, if the number of current use is not to should radio access technology types, smart card second number that will be defined as to switch to then to number that should radio access technology types, from the data that read second number in the information storage area of this second number under the corresponding catalogue of second number, with the network authentication information setting is the authentication information of second number, and the mode of operation of smart card is set to the network formats of the second number correspondence, use refreshing instruction afterwards, make terminal logging in network again, and then finish the process of the switching of standard internetwork number.
When triggering switching by country code, can be after the logging in network success, obtain current country code of providing services on the Internet, if in the network formats that smart card is supported, when the network formats that mates more with this country code is arranged, second number that will be defined as switching to the number of network formats that should country code, and switch.
When triggering switching by information of home location, can be after the logging in network success, obtain current regional information of providing services on the Internet, if the information of home location and the current regional information of first number of current use do not meet, and in the number that smart card is supported, when the number with this area's information matches is arranged, second number that the sign indicating number of corresponding this area information is defined as switching to, and switch, with use and the saving user rate of further being convenient to the user.
In order further to solve the problem that after start, can't obtain the network service with the 3G number as the intelligent card subscriber of primary number, the state that smart card is further served by registered network Service events monitoring network, when the network state after user's start is no network service or limiting network service, second number that the number of another network formats is defined as switching to then, and make terminal use second number to attempt logging in network again, thereby make the 3G intelligent card subscriber that has the networks with different systems number, can obtain preferable network service as much as possible.
When carrying out the number switching, smart card at first needs to determine second number that will switch to according to formulating good switching law, again according to switching flow, from the data that read second number in the information storage area of this second number under the corresponding catalogue of second number, with the network authentication information setting is the authentication information of second number, and the mode of operation of smart card is set to the network formats of the second number correspondence, and last triggering terminal is logging in network again.
The common employed triggering terminal mode of logging in network again is: send refreshing information to terminal, certainly those skilled in the art also can be by alternate manner triggering terminal logging in network again, for example utilize the signal of smart card pin to change, perhaps end communicating by letter of smart card and terminal room according to a preconcerted arrangement, when terminal does not receive the data that smart card sends in a period of time, logging in network again.Other triggering terminal well known to those skilled in the art mode of logging in network again is multiple in addition, just repeats no more at this.
Terminal is after receiving refreshing information, at first read the repositioning information of smart card, it is the mode of operation of smart card, definite network formats that will switch to, read the data of this number and pass through the corresponding network formats instruction realization and the data interaction of network side from corresponding catalogue again, and then finish network entry.
Further, because may be when carrying out the number switching, the user still has business to carry out under first number, for make switch back first number from second number after, can in time recover this business, can be before carrying out the number switching, preserve the number information memory block of the data of first number before switching earlier to the first number correspondence, like this, when switching back first number, can use the data of storing in the number information memory block of the first number correspondence to continue business in first number by second number.
Be that example is elaborated with the flow process that switches to the 2G number by the 3G number, switches back the 3G number more below:
Terminal is after start, according to setting in advance, usually use 3G USIM number logging in network earlier, after receiving the incident that triggers the switching of standard internetwork number, definite needs switch in the GSM network formats of 2G, then switching flow is: at first determine the number of 2G number for switching to, again from USIM (Universal Subscriber Identity Module, whole world Subscriber Identity Module) reads authentication sequence under the application catalogue and count 3G network number critical datas such as SQN, backup to 3G number information memory block, read KI KI from 2G number information memory block then, international mobile subscriber identity IMSI and short message centre number SMSC, being set to GSM uses under the catalogue, afterwards, by the smart card repositioning information is set, the mode of operation of smart card is set to the GSM standard, and terminal can be judged the type of smart card according to the repositioning information of smart card, be 2G pattern or 3G pattern, last smart card sends refreshing information to terminal by the REFRESH instruction.
Terminal is after receiving refreshing information, determine that according to the repositioning information of smart card mode of operation is the GSM standard, then read the number data under the GSM application catalogue, carry out network authentication according to GSM11.11, realize the data interaction of 2G network formats, obtain the service of 2G network.
When receiving the incident that triggers the switching of standard internetwork number and needing switch back the 3G network standard, then at first determine the number of 3G number for switching to, read international mobile subscriber identity IMSI from 3G number information memory block again, short message centre number SMSC, KI KI, the key OPC of operator, authentication sequence is counted SQN, the rotation constant ROT of authentication arithmetic, information such as authentication arithmetic constant group CONST, being set to USIM uses under the catalogue, can certainly preserve current business datum earlier and read the 3G data again to USIM application catalogue, afterwards, the repositioning information of smart card is set, promptly, the mode of operation of smart card is set to the USIM standard, at last, smart card sends refreshing information to terminal by the REFRESH instruction.
Terminal is after receiving refreshing information, determine that according to the repositioning information of smart card mode of operation is the USIM standard, then read the number data under the USIM application catalogue, carry out network authentications according to 3GPP 31.102, realize the data interaction of 3G network standard, obtain the 3G network service.
Owing in 3G number information memory block, store the 3G network number critical data of backup, so after obtaining the 3G network service, can directly use these data to continue to switch to the session of 3G network terminal and 3G network before the 2G standard, thereby further facilitate user's use.
