The method of mobile communication of the present embodiment includes following below scheme:

1, starting procedure 0 includes the steps that following sequence is executed for judging roaming state:

0-1: the terminal requests registered network using default account A1；

0-2: control module B data-reading unit B1 obtains the user identity of the default account A1 of SIM card modules A The subscriber identity information of information and primary account number A2, user's body of the control unit B2 judgement default account A1 of the control module B Whether part information identical as the subscriber identity information of primary account number A2: determine if the two is identical terminal be located at ownership place L or from Ownership place L enters the roaming state of roaming place R, into process I；0-3 is entered step if the two difference；

0-3: control module B data-reading unit B1 obtains terminal current network login state and judges: if Terminal network succeeds in registration, then determines that the terminal is turned back in roaming place R, terminate all processes；If network registry loses It loses, then determines that the terminal leaves roaming place R, enter step 0-4；

0-4: control module B data-reading unit B1 obtains the national code CT1 and master for the network that terminal searching arrives The national code CT3, the control unit B2 of the control module B of account A2 judges whether CT1 is identical as CT3: if the two is identical Then determine to return to ownership place L after terminal leaves roaming place R, into process III；Determine that terminal leaves roaming if the two difference Enter another roaming place RB after ground RA, into process II.

It should be understood that starting procedure 0 includes three determination steps: " 1, default account A1 and the comparison of primary account number A2 are sentenced It is fixed ", " 2, use the judgement of default account A1 request network registry state " and " 3, local networks national code and primary account number A2 are national The comparison of code determines ", the sequence of these three determination steps can be arbitrary, the combination of the judgement result of these three determination steps The roaming state of i.e. confirmable terminal.But due to " 2, use default account A1 request network registry state judgement " and " 3, The comparison judgement of local networks national code and primary account number A2 national code " step is not need to carry out in a part of roaming state , thus present embodiment preferentially takes said sequence.The starting procedure 0 can also obviously be sentenced using other Disconnected rule, which compares and analyzes these parameters, obtains terminal roaming status, can also be selected by human-computer interaction by user specific Roaming state.

In addition, control unit B4 can also be by comparison default account A1 with attached account A3 in the starting procedure 0 Difference to judge roaming state indirectly.But it is so to will appear some decision errors, such as: when default account A1 and attached account While A3 difference, also it is different from primary account number A2 (when run error when or default account storage region damage when often Occur).Thus preferably comparison defaults account and primary account number to ensure the accurate roaming state of terminal in starting procedure O.

2, communication terminal be located at ownership place or enter the process flow I of roaming place R from ownership place L as shown in figure 5, include with The step of lower sequence executes:

I-0: communication terminal carries out network registry using the subscriber identity information of default account A1, if network registry at Function then enters step I-1；If network registry fails, needs user voluntarily to contact operator's solution, terminate all processes；

I-1: control module B data-reading unit B1 obtains the national code CT1 of the current registered network of terminal, default account The national code CT2 of the subscriber identity information of the subscriber identity information and default account A1 of A1, the control list of the control module B First B2 judges whether CT1 is identical as CT2: if identical, illustrating that user is located at ownership place L, terminates all processes；If different It causes, illustrates that user enters roaming place R from ownership place L, enter step I-2；

I-2: control module communication unit B3 sends the order for requesting attached account A3 to supporting module C, takes in order Subscriber identity information (IMSI/ICCID) with CT1 and default account A1；

I-3: supporting module communication unit C4 receives and sends the order to user after the order for requesting attached account A3 SIM card administrative unit C1；User SIM card administrative unit C1 transfers SIM card list from storage unit C5 and judges: if described The subscriber identity information of default account A1 is present in the SIM card list, then enters step I-4；If the default account The subscriber identity information of A1 is not present in the SIM card list, then terminates all processes；

I-4: supporting module communication unit C4 sends the order for requesting attached account A3 to roaming place SIM card resource management Unit C2, roaming place SIM card rm-cell C2 transfer roaming place number resource list and number resource from storage unit C5 The judgement of distribution status information: if there is the attached account A3 of corresponding distribution in the subscriber identity information of the default account A1, The attached account A3 is then released to distribute, enter step I-5 after the relations of distribution in the distribution status information of modification number resource；Such as The subscriber identity information that account A1 is defaulted described in fruit is then directly entered step I-5 there is no the attached account A3 distributed is corresponded to；

I-5: supporting module communication unit C4 sends the order for requesting attached account A3 to number application unit C3, number Application unit C3 transfers roaming place number resource list and the distribution status information judgement of number resource from storage unit C5: if If the number resource of the also available free CT1 of roaming place number resource list, enter I-6；If roaming place number resource arranges The number resource of the not idle CT1 of table, then terminate all processes；

The vacant number resource of I-6: number application unit C3 one CT1 of distribution returns to terminal as attached account A3 Control module B, and record the relations of distribution；

I-7: control module communication unit B3 sends the number resource received to data write unit B2, data write-in Attached account storage region is written in attached account A3 information by unit B 2；

I-8: control module communication unit B3 sends call forwarding order to server-side, all of current default account A1 Calling is transferred to attached account A3 up；

I-9: data-reading unit B1 reads attached account A3 information, and data write unit B2 writes attached account A3 information Enter to default account storage region, and control SIM card and carry out electricity, re-power, communication terminal will re-search for and registered network.

After network registry success, for the operator of roaming place, the present sim card is exactly that one of own net is general The call rate for enjoying ordinary user is called the number of local user or calling party's home country by general family.

Preferably, control module B and supporting module C can transmit information by aerial encryption channel and interact.Certainly, Control module B and supporting module C can also be interacted by other modes such as internet access.

In the process I, since default account A1 is identical as primary account number A2, the order of the attached account of request can also To be changed to carry the subscriber identity information of primary account number A2.
