Embodiment Construction

[0064] The present invention provides a method and device. The basic idea is to store the downloadable files corresponding to the main control software used to increase the speed of the baseband processor and the business instruction data blocks used to realize the terminal business in the external memory. During the wake-up process of the terminal , under the control of the main control software, directly copy the service instruction data block from the external memory to the processor memory and load the service instruction data block through direct memory access (DMA) or memory copy mode.

[0065] As mentioned in the second solution above, the baseband processor must parse each block header field one by one, and then execute machine instructions, and the process of parsing one by one is obviously time-consuming. In particular, the conditional judgment of the read machine instructions is more obvious. Those skilled in the art know that the processing of a machine instruction...

Abstract

The invention provides a method for waking up a terminal, comprising steps of: storing the downloadable documents accelerating a base band processor and corresponding to the main control software guiding the operation of service software, and the service command data block for realizing terminal service in an external memory in advance; in the wake up process of the terminal, under the control ofthe main control software, accelerating the base band processor, adopting direct memory access or memory copy mode to directly copy the service command data block from the external memory to the memory of the processor, and guide the operation of the service command. The invention further provides a device waking up a terminal. Via the invention, a base band processor can directly operate the service command data block as machine instruction stored in the memory of the processor, to eliminate analysis, thereby realizing quick loading and guided operation of the service software in the wake upprocess of a terminal, to reduce the wake up time and prolong the standby time of the terminal.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and device for realizing wake-up of a terminal. Background technique [0002] When the mobile terminal is in the non-business state, that is, when there is no call or data transmission, it can also be said that in the standby process, in order to save power, it needs to enter the sleep state. However, due to the needs of network synchronization and network paging, the terminal also needs to be configured according to the network Periodically wake up to work state. [0003] figure 1 The state transition diagram of the terminal is shown. As shown in the figure, the terminal periodically switches between the sleep state and the working state. This cycle can be collectively referred to as the paging time, which is set to T, where the time spent in the sleep state is set to be T S , and the working state takes time T W . The working state includes three ...
