Therefore can in advance MCC, geographical position and one-to-one relationship therebetween be stored in the way of list inquiry. For example, by global positioning system (GlobalPositioningSystem, GPS), mobile phone detects that user is in Australia, then can get a MCC by this list of inquiry is 505. Then continue at step S102.
In step s 102, the 2nd MCC in a MCC and terminal RPLMN is contrasted by terminal. PLMN is made up of the decimal numeral mobile network code of MCC and two to three (MobileNetworkCode, MNC). Wherein MNC is for identifying the mobile network belonging to mobile client, and the MNC such as China Mobile is 00,02,04,06. For a mobile phone, generally require the multiple PLMN of maintenance, these networks and public switched telephone network interconnection, form the communication network of whole distract or Country Scale, have great importance. And in numerous PLMN, RPLMN has the highest priority, namely when carrying out PLMN and selecting, terminal will select RPLMN at first. And that RPLMN preservation is terminal PLMN in registration before shutdown last time or off-grid. Therefore the MCC in RPLMN often have recorded the conventional country belonging to ground of mobile phone, and when mobile phone detects that the MCC in MCC and the RPLMN that current geographic position is corresponding differs, it was shown that mobile phone there occurs roaming. Then continue at step S103.

Namely the PLMN wherein contracted can provide the user the operator of network service, and such terminal is known which network operation chamber of commerce of this roaming place provides network service. Also to shield the MCC network formats do not supported and frequency range simultaneously, such as due to Africa mobile communication technology comparatively falls behind does not support 4G network, when a mobile phone supporting 4G network then can shield 4G network and frequency range thereof when Africa, to reduce useless web search. And for example in China, it is provided that there are China Mobile, CHINAUNICOM etc. in the operator of 4G network. Wherein the 4G frequency range of China Mobile is 1880-1900MHz, 2320-2370MHz, 2575-2635MHz, and the 4G frequency range of CHINAUNICOM is 2300-2320MHz, 2555-2575MHz, it can be seen that their frequency range is mutually different. Owing to the 4G network coverage face of CHINAUNICOM is wider, it is thus possible to the 4G Virtual network operator in certain area only has CHINAUNICOM, therefore the spectrum mask that CHINAUNICOM does not support can be fallen when this mobile phone is in this area, to reduce useless frequency band search. So can improve terminal and obtain the speed of network service. Then continue at step S104.
In step S104, the PLMN contracted in step S103 is set to RPLMN by terminal, thus RPLMN is revised as RPLMN accurately. So can search for the identical community of PLMN and RPLMN targetedly, thus improving roaming place terminal to obtain the speed of network service.
The registered public land mobile network method of this preferred embodiment is by being modified as roaming place PLMN by terminal RPLMN from conventional ground PLMN when terminal is in roaming, to improve the accuracy of RPLMN, and by shielding network formats and the frequency range that roaming place is not supported, thus jointly improve roaming place terminal to obtain the speed of network service.

Refer to the flow chart of the second preferred embodiment of the registered public land mobile network amending method that Fig. 2, Fig. 2 are the present invention. The method is for modifying to the RPLMN of terminal. Wherein, this terminal can be the electronic equipment equipped with SIM such as mobile phone, panel computer. The registered public land mobile network amending method of this preferred embodiment includes:
Step S201, obtains the MCC that terminal current geographic position is corresponding;
Step S202, contrasts the 2nd MCC in a MCC and terminal RPLMN;
Step S203, as MCC and the two MCC differs, then obtains the PLMN contracted corresponding to a MCC, and shields the MCC network formats do not supported and frequency range;
Step S204, is set to RPLMN by the PLMN contracted.
Step S205, it is judged that whether there is first community corresponding with RPLMN in cell data base;
Step S206, as step S205 judges to exist in cell data base first community corresponding with RPLMN, then searches for the first community near terminal;
Step S207, it may be judged whether search the first community near terminal;
Step S208, as step S207 judges to search the first community, then by endpoint registration the first community;
Step S209, judges to be absent from cell data base first community corresponding with RPLMN such as step S205 or step S207 judges not search the first community, then the second community near search terminal.
Step S210, it is judged that whether the PLMN of the second community is identical with RPLMN;
Step S211, as step S210 judges that PLMN and the RPLMN of the second community is identical, then by endpoint registration the second community;
Step S212, as step S210 judges that PLMN and the RPLMN of the second community differs, then prompting user's registration failure.
The idiographic flow of each step the following detailed description of the registered public land mobile network amending method of this preferred embodiment.
In step s 201, the MCC that terminal current geographic position is corresponding is obtained. Wherein, the country that the terminal that current geographic position refers to is currently located. MCC is made up of three decimal numbers, it was shown that the country of mobile user affiliation, for instance 460 represent China, and 505 represent Australia. Therefore can in advance MCC, geographical position and one-to-one relationship therebetween be stored in the way of list inquiry. For example, by GPS, mobile phone detects that user is in Australia, then can get a MCC by this list of inquiry is 505. Then continue at step S202.
In step S202, the 2nd MCC in a MCC and terminal RPLMN is contrasted by terminal. PLMN is made up of the decimal numeral MNC of MCC and two to three. Wherein MNC is for identifying the mobile network belonging to mobile client, and the MNC such as China Mobile is 00,02,04,06. For a mobile phone, generally require the multiple PLMN of maintenance, these networks and public switched telephone network interconnection, form the communication network of whole distract or Country Scale, have great importance. And in numerous PLMN, RPLMN has the highest priority, namely when carrying out PLMN and selecting, terminal will select RPLMN at first. And that RPLMN preservation is terminal PLMN in registration before shutdown last time or off-grid. Therefore the MCC in RPLMN often have recorded the conventional country belonging to ground of mobile phone, and when mobile phone detects that the MCC in MCC and the RPLMN that current geographic position is corresponding differs, it was shown that mobile phone there occurs roaming. Then continue at step S203.

Also to shield the MCC network formats do not supported and frequency range simultaneously, such as due to Africa mobile communication technology comparatively falls behind does not support 4G network, when a mobile phone supporting 4G network then can shield 4G network and frequency range thereof when Africa, to reduce useless web search. And for example in China, it is provided that there are China Mobile, CHINAUNICOM etc. in the operator of 4G network. Wherein the 4G frequency range of China Mobile is 1880-1900MHz, 2320-2370MHz, 2575-2635MHz, and the 4G frequency range of CHINAUNICOM is 2300-2320MHz, 2555-2575MHz, it can be seen that their frequency range is mutually different. Owing to the 4G network coverage face of CHINAUNICOM is wider, it is thus possible to the 4G Virtual network operator in certain area only has CHINAUNICOM, therefore the spectrum mask that CHINAUNICOM does not support can be fallen when this mobile phone is in this area, to reduce useless frequency band search. So can improve terminal and obtain the speed of network service.
Preferably, as identical in MCC and the two MCC, then illustrate that terminal is not roamed, therefore without RPLMN is modified.
In step S204, the PLMN contracted in step S203 is set to RPLMN by terminal, thus RPLMN is revised as RPLMN accurately. Then continue at step S205.
In step S205, whether terminal judges cell data base exists first community corresponding with RPLMN. Wherein, community is the minimum territorial unit inside mobile management, and effective coverage distance of a such as base station is 10 kms, then with this base station for the center of circle, circle this base station i.e. that 10 kms are radius covers " community " that formed, and in this community, mobile phone can communicate with this base station. Due to, when user roams, first stop is all big harbour, air harbor and railway terminal, therefore terminal can obtain community and the relevant information thereof of these areas adjacent in advance, wherein relevant information includes the information such as network formats, frequency range, PLMN, position, again these communities, relevant information and incidence relation thereof are set up association and be stored in cell data base, the community that during for roaming, mobile phone quick obtaining can be registered, thus reducing the time obtaining network service. If cell data base exists multiple community corresponding with RPLMN, then can in conjunction with the positional information of these communities, the community that prioritizing selection is nearest with terminal current location, to improve the accuracy of community. When there is first community corresponding with RPLMN in terminal judges cell data base, then proceed to step S206; In terminal judges cell data base, it is absent from first community corresponding with RPLMN, then proceeds to step S209.
In step S206, as step S205 judges to exist in cell data base first community corresponding with RPLMN, then terminal can nearby search for this first community targetedly, thus providing search efficiency. Then continue at step S207.
In step S207, whether terminal judges nearby searches the first community. As searched, proceed to step S208; As do not searched, proceed to step S209.
In step S208, as step S207 judges to search the first community, then by this first community of endpoint registration, to obtain network service.
In step S209, cell information owing to prestoring is comprehensive not, it is possible to cause being absent from first community corresponding with RPLMN in cell data base, or due to the first community from terminal position too away from, cause that terminal searching is less than the first community, then the second community near terminal searching. Due to the network formats do not supported roaming place already in step S203 and spectrum mask, therefore substantially increase search efficiency. Then continue at step S210.
In step S210, whether the PLMN of terminal judges the second community is identical with RPLMN, as identical, proceeds to step S211; Step S212 is then proceeded to such as difference.
In step S211, as step S210 judges that PLMN and the RPLMN of the second community is identical, illustrate that terminal can be passed through this second community and obtain network service, therefore register the second community.
In step S212, as step S210 judges that PLMN and the RPLMN of the second community differs, illustrate do not have community can provide network service to terminal, therefore prompting user's registration failure.

Judge to exist in cell data base first community corresponding with RPLMN as the first community exists judge module 406, then the first cell search module 407 can nearby search for this first community targetedly, thus providing search efficiency. Call the first cell searching judge module 408 subsequently.
Then, the first cell searching judge module 408 judges whether nearby to search the first community. As searched, call registration the first community module 409; As do not searched, call the second cell search module 410.
As the first cell searching judge module 408 judges to search the first community, then register the first community module 409 by this first community of endpoint registration, to obtain network service.
Cell information owing to prestoring is comprehensive not, may result in cell data base is absent from first community corresponding with RPLMN, or due to the first community from terminal position too away from, cause that the first cell search module 407 is searched for less than the first community, then can pass through the second cell search module 410 and search for the second neighbouring community. The network formats do not supported roaming place already due to acquisition and shroud module 404 and spectrum mask, therefore substantially increase search efficiency. Call public land mobile network judge module 411 subsequently.
Thereafter, public land mobile network judge module 411 judges that whether the PLMN of the second community is identical with RPLMN, as identical, calls registration the second community module 412; Registration failure reminding module 413 is then called such as difference.
As public land mobile network judge module 411 judges that PLMN and the RPLMN of the second community is identical, illustrate that terminal can be passed through this second community and obtain network service, therefore register the second community module 412 by endpoint registration the second community.
As public land mobile network judge module 411 judges that PLMN and the RPLMN of the second community differs, illustrating do not have community can provide network service to terminal, therefore registration failure reminding module 413 points out user registration failure.
On the basis of the first preferred embodiment, the registered public land mobile network device of this preferred embodiment is further by being modified as roaming place PLMN by terminal RPLMN from conventional ground PLMN when terminal is in roaming, to improve the accuracy of RPLMN, and further by shielding network formats and the frequency range that roaming place is not supported, jointly improve roaming place terminal and obtain the speed of network service.
