If the terminal equipment is off-line, firstly searching the serving cell frequency point and the adjacent cell frequency point in the frequency point record list, if the searching is successful, the network searching is successful, the terminal equipment resides in the searched cell, then initiating a registration process, and after the corresponding process is executed, ending the process.
202. Judging whether the search frequency point is searched successfully or not; if not, go to step 203, if yes, stay in the searched cell and initiate the registration process.
203. Searching first frequency range information corresponding to the HPLMN and the RPLMN; if the first frequency band information is not searched, turning to step 204; and if the first frequency band information is searched successfully, residing in the searched cell and initiating a registration process.
204. If the first frequency band information is searched unsuccessfully, searching second frequency band information corresponding to the non-HPLMN and the non-RPLMN, wherein the second frequency band information is different from the first frequency band information; if the second frequency band information is not searched, go to step 208; if the second frequency band information is successfully searched, go to step 205.

211. A first distance between the second location information and the first location information is obtained.
If the terminal equipment moves, whether the movement of the terminal equipment can preliminarily consider that the nearby network changes or not is further judged according to the distance.
For example, the first distance may be N meters, and N is an integer, where N may be set by a user according to actual circumstances. When the terminal device is in a high-speed moving state, it can be considered that the first distance of the terminal device is also larger in the process of moving from the non-HPLMN to the HPLMN.

Touch panel 1131, also referred to as a touch screen, can collect touch operations of a user on or near the touch panel 1131 (for example, operations of the user on or near touch panel 1131 by using any suitable object or accessory such as a finger or a stylus pen), and drive corresponding connection devices according to a preset program. Alternatively, the touch panel 1131 may include two parts, namely, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 1180, and can receive and execute commands sent by the processor 1180. In addition, the touch panel 1131 can be implemented by using various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 1130 may include other input devices 1132 in addition to the touch panel 1131. In particular, other input devices 1132 may include, but are not limited to, one or more of a physical keyboard, function keys (e.g., volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.
The display unit 1140 may be used to display information input by the user or information provided to the user and various menus of the cellular phone. The display unit 1140 may include a display panel 1141, and optionally, the display panel 1141 may be configured in the form of a Liquid Crystal Display (LCD), an organic light-Emitting diode (OLED), or the like. Further, the touch panel 1131 can cover the display panel 1141, and when the touch panel 1131 detects a touch operation on or near the touch panel, the touch panel is transmitted to the processor 1180 to determine the type of the touch event, and then the processor 1180 provides a corresponding visual output on the display panel 1141 according to the type of the touch event. Although in fig. 6, the touch panel 1131 and the display panel 1141 are two independent components to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 1131 and the display panel 1141 may be integrated to implement the input and output functions of the mobile phone.
The handset may also include at least one sensor 1150, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 1141 according to the brightness of ambient light, and the proximity sensor may turn off the display panel 1141 and/or the backlight when the mobile phone moves to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.
WiFi belongs to short-distance wireless transmission technology, and the cell phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 1170, and provides wireless broadband internet access for the user. Although fig. 6 shows the WiFi module 1170, it is understood that it does not belong to the essential constitution of the handset, and can be omitted entirely as needed within the scope not changing the essence of the invention.
The processor 1180 is a control center of the mobile phone, and is connected to various parts of the whole mobile phone through various interfaces and lines, and executes various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 1120 and calling data stored in the memory 1120, thereby performing overall monitoring of the mobile phone. Optionally, processor 1180 may include one or more processing units; preferably, the processor 1180 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated within processor 1180.
The phone also includes a power supply 1190 (e.g., a battery) for powering the various components, and preferably, the power supply may be logically connected to the processor 1180 via a power management system, so that the power management system may manage charging, discharging, and power consumption management functions. Although not shown, the mobile phone may further include a camera, a bluetooth module, etc., which are not described herein.
