Embodiment 1

[0045] This embodiment provides a mobile phone, such as figure 1 As shown, it includes a Modem1, a GSM module 2, a CDMA module 3, a WCDMA module 4, a receiving module 5 and a screening module 6.

[0046] When the mobile phone is not inserted with a SIM card, the GSM module 2 is used to send a generalized AT instruction request to the base station of GSM through the Modem; A generalized AT command request is sent for a CDMA base station; the WCDMA module 4 is used to send a generalized AT command request to a base station whose communication system is WCDMA 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 the area are: when the communication system is GSM, the first base station and the second base station assigned by the mobile phone operator China Mobile, the mobile phone operator The third base station allocated by China Unicom; th...

Embodiment 2

[0061] This embodiment provides a mobile phone, such as image 3 As shown, the difference between the mobile phone of this embodiment and Embodiment 1 is that the mobile phone of this embodiment also includes a display module 7 and an update module 8, and the display module 7 is used to display the registrable information on the screen of the mobile phone. The GSM module 2, the CDMA module 3 or the WCDMA module 4 are also used to periodically send the AT command request to the base station of each communication system, such as every 20s; the update module 8 is used for the base station information currently received by the receiving module The display of registrable information is updated when it is different from 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 by using the mobile phone in Embodiment 2, such as Figure 4 As shown, the d...

Abstract

The invention discloses a method for obtaining the information of a base station through a cellphone, and the cellphone. The cellphone comprise a Modem, a GSM module, a CDMA module, a WCDMA module, a receiving module, and a screening module. The GSM module, the CDMA module and the WCDMA module are used for sending a base station information request to base stations with different communication modes through the Modem when an SIM card is not inserted into the cellphone. The receiving module is used for receiving the base station information fed back by a base station receiving the base station information. The screening module is used for screening out registerable information from the base station information. The cellphone can send a request to the base station when the SIM card is not inserted into the cellphone, screens out registerable information from a plurality of pieces of obtained base station information, selects one base station with the highest signal intensity for registration according to the registerable information, prevents the repeated inserting and pulling of the SIM card from causing the damage to a card slot, and improves the quality of the subsequent communication of a user side.

Description

technical field [0001] The invention relates to a method for a mobile phone to obtain base station information without a SIM (Subscriber Identity Module, customer identification module) card and the mobile phone. Background technique [0002] At present, the mobile phone usually sends a request message to a base station in the signal coverage area where the mobile phone is located through the SIM card in the state of having a SIM card, so that the mobile phone is directly registered with the base station, thereby realizing communication between the mobile phone and the mobile phone. Since the user does not know which operator's mobile phone signal strength is better, this method of only registering to a certain base station will generally not obtain the base station with the best signal strength, which will cause trouble for the user to make a call. [0003] If the SIM card is inserted and removed repeatedly to test and compare, so that the mobile phone is registered to the ...
