Example Embodiment

[0044] Example 1

[0045] This embodiment provides a mobile phone, such as figure 1 As shown, it includes a Modem 1, a GSM module 2, a CDMA module 3, a WCDMA module 4, a receiving module 5 and a screening module 6.

[0046] When the SIM card is not inserted in the mobile phone, the GSM module 2 is used to send a generalized AT command request to the base station whose communication mode is GSM through the Modem; the CDMA module 3 is used to send a generalized AT command request through the Modem to the communication mode Send a generalized AT command request for a CDMA base station; the WCDMA module 4 is used to send a generalized AT command request to a base station with a WCDMA communication standard through the Modem.

[0047] Among them, the content of each AT command is different. Assuming that the area where the mobile phone is located is at the foot of Mount Tai, the base stations near this area are: when the communication mode is GSM, the first base station and the second base station allocated by the mobile phone operator China Mobile, the mobile phone operator The third base station allocated by China Unicom; when the communication format is CDMA, the fourth base station allocated by mobile phone operator China Telecom; when the communication format is WCDMA, the fifth and sixth base stations allocated by mobile phone operator China Unicom.

[0048] The content of the generalized instruction can be a request similar to "AT+CREG?". The instruction can query the base station number and cell ID (Identity, identification number, used to identify an object). To obtain more base station information, the content of the AT command needs to be rewritten for base stations of different communication standards.

[0049] The receiving module 5 is configured to receive base station information fed back by the base station that receives the AT command.

[0050] Due to factors such as distance or electromagnetic interference, not all base stations may be able to receive the base station information request. It is assumed that only the second base station receives the AT command request issued by the GSM module, and the fourth base station receives the request issued by the CDMA module. AT command request, the fifth base station receives the AT command request sent by the WCDMA module, so the second base station, the fourth base station and the fifth base station will feed back their own information to the receiving module.

[0051] Assume that the base station information fed back by the second base station, the fourth base station, and the fifth base station are base station number, base station signal strength, base station frequency, scrambling code, network type, mobile device country code, mobile network number, location area code, and base station Signal strength. Among them, the values of the base stations are all or partly different, and the base station information fed back can be presented in the form of a character string, and the base station information forms a multi-dimensional array.

[0052] The screening module 6 is used to screen out a piece of registrable information from the base station information, and the registrable information includes mobile device country code, mobile network number, location area code, base station number, and base station signal strength, so the registrable information Then, the mobile phone can be registered to a second base station of China Mobile, the fourth base station of China Telecom, or the fifth base station of China Unicom after the mobile phone is loaded into the SIM.

[0053] After screening the registrable information from the base station information fed back by the second base station, the fourth base station and the fifth base station, the base station with the strongest signal is selected for registration based on the magnitude of the base station signal strength value fed back, avoiding repeated insertion and removal The damage of the SIM card to the card slot also improves the call quality of subsequent calls at the user end.

[0054] This embodiment also provides a method for a mobile phone to obtain base station information, which is implemented using the mobile phone of Embodiment 1, such as figure 2 As shown, including the following steps:

[0055] Step 101: When the SIM card is not inserted in the mobile phone, the GSM module sends an AT command request through the Modem to the base station whose communication mode is GSM; after 3s, the CDMA module sends the communication mode to CDMA via the Modem. The base station sends an AT command request; after another 3s, the WCDMA module sends an AT command request to the WCDMA base station through the Modem; the content of these AT command requests is different, and the three modules are sent The order of requests is not restricted by this.

[0056] Step 102: The receiving module receives a piece of base station information fed back by the base station that received the AT command request;

[0057] That is, the base station information received from the second base station, the fourth base station, and the fifth base station is the base station number, base station signal strength, base station main frequency, scrambling code, network type, mobile device country code, mobile network number, location area code, and The signal strength of the base station, and the latitude and longitude position of the base station can be obtained by converting the actual geographic location, and the values in the information of the base stations are different in whole or in part.

[0058] Step 103: The screening module screens out a piece of registrable information from the base station information through a string index, and the registrable information is used for the mobile phone to register to a base station that feeds back the base station information.

[0059] Among them, the registrable information includes the country code of the mobile device, the mobile network number, the location area code, the base station number, and the base station signal strength, so that the mobile phone can register to the second base station with the GSM communication system and the communication system with the CDMA after the SIM is installed. The fourth base station and the fifth base station whose communication standard is WCDMA.

Example Embodiment

[0060] Example 2

[0061] This embodiment provides a mobile phone, such as image 3 As shown, the difference between the mobile phone of this embodiment and the first embodiment is that the mobile phone of this embodiment further includes a display module 7 and an update module 8. The display module 7 is used to display the registrable information on the screen of the mobile phone. The GSM module 2, CDMA module 3, or WCDMA module 4 is also used to periodically send the AT command request to the base station of each communication standard, such as every 20s; the update module 8 is used to update the base station information currently received by the receiving module Update the display of registerable information at the same time as the base station information received last time.

[0062] Correspondingly, this embodiment also provides a method for a mobile phone to obtain base station information, which is implemented using the mobile phone of Embodiment 2, such as Figure 4 As shown, the difference between this method and the method of Embodiment 1 is that: after step 103, the method further includes:

[0063] Step 104: The display module displays the registerable information on the screen of the mobile phone.

[0064] Step 105: After 20s, when the SIM card is not inserted in the mobile phone, the GSM module sends the AT command request to the base station whose communication mode is GSM through the Modem; after 3s, the CDMA module passes The Modem sends the AT command request to a base station whose communication mode is CDMA; After another 3s, the WCDMA module sends the AT command request to a base station whose communication mode is WCDMA through the Modem;

[0065] Step 106: The receiving module receives a piece of base station information fed back by the base station that receives the AT command request;

[0066] Step 107: The update module judges whether the base station information currently received by the receiving module is the same as the base station information received last time, if yes, go to step 108, if not, go to step 109;

[0067] Step 108: The display module continues to display the last registrable information, and then returns to step 105;

[0068] Step 109: The filtering module filters out the current registrable information from the base station information currently received by the receiving module through the string index, and the current registrable information is used for the mobile phone to register to a base station that feeds back the base station information. The base station, the display module updates the displayed last registrable information to the current registrable information, and then returns to step 105.

[0069] It can be seen that while achieving the effect of embodiment 1, this embodiment also has the following effects: the display module can display the registrable information in a page format, and the update module focuses more on the base station information received by the receiving module and the last time. If it is not updated at the same time, it will be continuously compared with the last base station information to form a loop. When the base station information received twice adjacently is the same, the filtering step of the current base station information obtained is omitted, and only for the received base station information. The base station information is updated and displayed under different conditions, which enables users to obtain the latest and most complete base station information as soon as possible, and improves the processing efficiency of the equipment.
