After power up, the system and method for reducing the time for starting the acquisition of the cellular network

摘要

The selected system solution for use in a wireless device, the system selection file is read universal integrated circuit card (UICC), and can be converted to the preferred list. Specify the relative priority of the 3GPP2 system and 3GPP system, priority list, can manage the system selected by the device. Conventionally, generation of a priority list may be executed at power up each device. However, to read the file system selected from the UICC, and can generate a priority list, takes a time, and can adversely affect the performance of the device. For certain aspects of the present disclosure, but only if the system selection file is changed, the priority list may be generated after power. Therefore, the power of the device is turned on, in particular, the time to acquire the wireless device may be reduced when the system selection file is maintained the same as before.
