Abstract

The invention discloses a method and system for starting sleep and wakeup modes. The method comprises the following steps that a communication terminal judges to start a work state or finish the work state; the communication terminal transmits a wakeup control signal to a GPRS (general packet radio service) module through a control pin if needing to start the work state, and the GPRS module generates interruption, starts a wakeup mode and forbids the control pin generating the interruption when detecting the wakeup control signal; the communication terminal transmits a sleep control signal to the GPRS module if finishing the work state; and the GPRS module starts the sleep mode and allows the control pin to generate the interruption after receiving the sleep control signal. Through the method for starting the sleep and wakeup modes, disclosed by the invention, the standby current of the GPRS module is reduced, and the great amount of consumed electric energy is avoided; and meanwhile, the heat of the GPRS module is relatively reduced when the standby current is reduced so that the service life of the GPRS module is prolonged.

Description

technical field

[0001] The invention relates to the field of wireless communication, in particular to a method and a system for a GPRS module to enter sleep and wake-up modes. Background technique

[0002] In recent years, with the rapid development of wireless communication technology, wireless communication equipment has been widely used in various fields, and the General Packet Radio Service (GPRS, General Packet Radio Service) module is one of them. The GPRS module is a device that realizes modulation and demodulation of packet switching communication. With this module, functions such as Internet access and location locking can be realized. In addition, the GPRS module can also be controlled by a modem command (AT command) to realize voice calls Features.

[0003] In the prior art, the GPRS module can be connected to an external communication terminal through an expansion interface to realize communication functions. For example, the GPRS module in the live star perform...
