Fig. 3 is IMSI information amending method flow chart of the embodiment of the present invention, IMSI information amending method as shown in Figure 3,
Comprise the following steps：
Step 300, wireless terminal establish machine by cable on reaching the standard grade, and carry out initial work.
In general, establish by cable in terminal of starting shooting after the completion of initializing after machine, into working condition.
After start, terminal carries out band scan, and selection is resided in suitable cell.The launch position in resident cell
Registration and the process of route registration, obtain normal network service.Prior art is initialized as in terminal after electricity, the present invention is not done
It is described in further detail.
Step 301：Net pattern information is looked in acquisition, and judgement looks for whether net pattern is designated as automatically；
When looking for net pattern information to be designated as automatic, step 302, when looking for net pattern to be designated as manual, flow knot are performed
Beam.
In the present embodiment, look for net pattern to be divided into manually and automatically, it can be factory preset to look for net pattern, can also by with
Family is voluntarily set.Net pattern information is looked for be stored in the nonvolatile storage (Nonvolatile Memory, NV) of terminal
Obtain present terminal looks for net pattern, wherein 0 represents that it is automatic to look for net pattern, 1 represents that it is manual to look for net pattern, and the present invention is to this
Do not limit.
Step 302, obtain current radio resource control (Radio Resource control, RRC) state；
Step 303, obtain the Mobile Country Code MCC of terminal first (Mobile Country Code, MCC), the first mobile network
Number (Mobile Network Code, MNC), the 2nd MCC and the 2nd MNC；
In the present embodiment, wherein, the first MCC refers to the MCC of home network, and the first MNC refers to home network
MNC, the 2nd MCC refer to the MCC of registered network, and the 2nd MNC refers to the MNC of registered network.
, can be from the IMSI of terminal or single one piece of memory block if IMSI is not changed in the present embodiment
Present terminal home network MCC and MNC are obtained in domain, if IMSI is changed, it is necessary in the single one piece of storage region of follower
Obtain the MCC and MNC of home network；Registered network MCC and MNC are obtained in cell broadcast messages.IMSI is international mobile subscriber
Identification code, it is stored at the beginning in SIM card, it is necessary to which home network MNC and MCC are backed up single one after first time plug-in card
In block storage region.IMSI includes MCC fields, MNC fields, identification number of mobile subscriber (Mobile Subscriber
Identification Number, MSIN) field and other fields.For example Chinese user carries mobile terminal to Japan, registration
In day present networks, the home network MCC obtained from IMSI is 460 (Chinese Mobile Country Code MCCs), from cell broadcast messages
The registered network MCC of middle acquisition is 440 (Japanese Mobile Country Code MCCs).
It should be noted that the order of step 303 does not limit, complete to realize that the present invention is real before step 305
The purpose of example is applied, is illustrated in the embodiment of the present invention by taking step 303 as an example, does not investigate other embodiments.
Step 304, whether at the idling mode to judge present terminal.
If it is, step 305 is performed, if not, continuing executing with step 304.
In the present embodiment, current RRC state is obtained from RRC state event notification message signaling.Such as 0 instruction state be
Idle pulley, 1 is designated as connection mode.Network service is obtained, is normally resided in after network, from physical layer RRC state event
The RRC state of present terminal is obtained in notification message signaling, RRC state value 1 represents connection mode, and 0 represents idle pulley.It is empty
Not busy pattern refers to present terminal and is attached on network, obtains network service, but does not have signaling connection between network non-access stratum,
Terminal can carry out cell selection and network selection at the idling mode.Connection mode, which refers between terminal and network, short message, electricity
The related service connection such as words, data, network side and terminal can transmit data.
Step 305, when the RRC state is designated as idle pulley, judge whether terminal is resided on visited network；
Wherein, judge whether terminal is resided on the network of visit to specifically include：
Judge whether the first MCC and the 2nd MCC are identical；
If the first MCC and the 2nd MCC are differed, judge that terminal is resided on the network of visit, and perform step 306,
If the first MCC and the 2nd MCC are identical, judge that terminal is not resident in return to step 302 on the network of visit；
Step 306, MCC fields in the IMSI and MNC fields be respectively modified as the 2nd MCC and the 2nd MNC；
Step 307, the identification information formed according to the 2nd MCC in the IMSI and the 2nd MNC initiate to look for net to ask.
The MCC and MNC of original home network in IMSI are replaced with the MCC and MNC of registered network, other fields are kept not
Become, terminal obtains normal network service.Reside on network, obtain network service, bottom stops search home network.
Step 308：Show roaming state；
Terminal at the idling mode, obtains proper network service.MCC, MNC and the MCC of registered network for being obtained in IMSI,
MNC is identical, and terminal stops on the home network, and the home network search timer before stopping, physical layer stops to home network
The frequency sweep search of network, but really roaming state, this step will show roaming state to user.
Step 309, in the case of the first MCC and the 2nd MCC identicals, by MCC fields and movement in IMSI
Network code MNC fields revert to the first MCC and the first MNC.
MCC and MNC fields in IMSI information are unable to accurate representation home network information, therefore actual home network MCC is deposited
Store up in the NV regions of terminal, in the case of non-roaming, MCC and MNC fields in IMSI will be reverted into actual home network
MCC and MNC information.
This implementation provides a kind of IMSI information amending method, by the method for IMSI Dynamic Matchings, initiates new to look for net
Request, is attached on network and obtains normal service, search of the bottom to home network under idle pulley is stopped at, so as to reduce end
The battery electric quantity of end at the idling mode.
User carries mobile terminal device and gone abroad, and after starting up of terminal registered network, is registered on the network of visit, in sky
Bottom is ceaselessly to home network search under not busy pattern, applies this programme this when, bottom to the MCC fields in IMSI and
MNC fields enter line replacement, initiate to look for net again, can so make mobile terminal resident on the home network, bottom stops to returning
Belong to the search of network, and the service that conveniently can be brought using local network.The setting applies in general to travelling merchants' use
Family, particularly that user for often going out international difference.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
