Table 1
For example, portable terminal is the double model double standby phone of the TD (TD-SCDMA)/G (GSM)+W (WCDMA)/G (GSM) of the B of operator, needs the W network of the SIM card of the restriction A of operator.It is A that information acquisition unit 201 is obtained the operator that judges SIM card for IMSI number, the first judging unit 2021 is judged as restriction operator, the second judging unit 2022 is further judged the duplexer control signal again, first question blank 1 specifically, find out the frequency range of present duplexer control signal, for example be the W frequency range of the UMTS TRX2 in the table 1 (ANT_SEL＜0...3〉be 1011); Then judge that based on a restriction band table whether the W frequency range is the restriction frequency range, has suffered because the W frequency range has been arranged in advance the restriction band table, so the judged result of the second judging unit 2022 is yes.
The various examples of the control module 202 among Fig. 4 can be attached in the portable terminal among Fig. 1, Fig. 2, Fig. 3.
Refer again to Fig. 5, Fig. 5 is the encryption method in one embodiment of the invention, is used for encrypting portable terminal, and portable terminal for example can be the portable terminal among Fig. 1-4 and various example thereof.
As shown in Figure 5, encryption method comprises:
Step 51: the information of obtaining the SIM card that is inserted in deck;
Step 52: according to the information of SIM card, control opening or closing of radio-frequency antenna switch.
Wherein, in step 51, can be obtained by the communication process of acquisition of information module 201 monitoring primary processors 10 and SIM card, for example obtain IMSI number, judge the operator of SIM card etc.
Step 521: whether the operator of judging SIM card is restriction operator;
Step 522: when step 521 when the determination result is NO, then the duplexer control signal is outputed to the radio-frequency antenna switch.
Wherein, in step 521, judge when whether operator is restriction operator, can show to judge based on a restriction operator, in restriction operator table, search coupling, be restriction operator if operator in restriction operator table, then is judged to be the operator of SIM card, otherwise the operator that then is judged to be SIM card is unrestricted operator.
Please continue with reference to figure 6, further, step 52 also comprises:
Step 523: whether the frequency range of judging the duplexer control signal is the restriction frequency range;
Step 524: if then close the corresponding band of radio-frequency antenna switch.
Certainly, if step 523 when the determination result is NO, then carry out step 522.
Wherein, in step 523, determining whether to limit frequency range can judge based on a duplexer truth table, such as table 1, the concrete process of judging and how to use table 1 when the structure function of aforementioned description portable terminal and encryption device, to introduce in detail, succinct for specification is not described in detail in this.
Please refer to Fig. 7, Fig. 7 is the concrete steps of step 524, comprising:
Step 5241: the duplexer control signal after replacement duplexer control signal obtains to reset;
Step 5242: the duplexer control signal after will resetting is exported to the radio-frequency antenna switch.
In step 5241, can be based on the replacement duplexer information of showing to reset, for example when the W frequency range is the restriction frequency range, reset cell 2023 finds replacement duplexer control signal corresponding to W frequency range at the replacement table, for example reset to the SLEEP pattern, i.e. (ANT_SEL＜0...3〉be 0000) so just reached the purpose of hardware lock network frequency locking section.In other embodiments, those skilled in the art can be according to predetermined policy reset antenna control signal, for example other patterns in the table 1.
In another embodiment, step 524 can directly disconnect the duplexer control signal, is not transferred to the radio-frequency antenna switch.
When the encryption method of the present embodiment is applied to portable terminal shown in Figure 2, can also judge that whether SIM card is the restriction SIM card, if so, then disconnects the SIM card signal according to the information of SIM card.Therefore, can on the basis of realizing lock network frequency locking section, realize simultaneously the function of pintle hook lock.
One embodiment of the invention adopts a kind of hardware encipher device to encrypt a portable terminal, by the technique effect that opens or closes to realize hardware lock network frequency locking section of control radio-frequency antenna switch.Therefore, safe, and can the heterogeneous networks of frequency range and same operator be locked.
Further, also adopted the pintle hook lock module, can lock the restriction card, so can on the basis that reaches lock network frequency locking section, reach simultaneously the effect of pintle hook lock.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
