The memory may include a Read-Only Memory (ROM) and a Random Access Memory (RAM) and provides an instruction and data for the processor. A part of the memory may further include a nonvolatile RAM. For example, the memory may further store information of a device type. The processor may be configured to execute the instruction stored in the memory, and when the processor executes the instruction, the processor may execute each step corresponding to the terminal equipment in the abovementioned method embodiments.
In an implementation process, each step of the method may be completed by an integrated logic circuit of hardware in the processor or an instruction in a software form. The steps of the method disclosed in combination with the embodiments of the disclosure may be directly embodied to be executed and completed by a hardware processor or executed and completed by a combination of hardware and software modules in the processor. The software module may be located in a mature storage medium in this field such as a RAM, a flash memory, a ROM, a programmable ROM or electrically erasable programmable ROM and a register. The storage medium is located in the memory, and the processor reads the instruction in the memory, and completes the steps of the method in combination with hardware. No more detailed descriptions will be made herein to avoid repetitions.
It is to be understood that the above descriptions about the embodiments of the disclosure are made with emphasis on differences between each embodiment and the same or similar parts which are not mentioned may refer to each other and will not be elaborated herein for simplicity.
