Abstract

The invention discloses a method and a device for realizing a GSM0710 protocol in a LINUX kernel, and relates to an electronic information product. The method comprises the following steps: a TTY logic channel driving module used for driving a GSM0710 specification logic channel is arranged to open or close a logic channel corresponding to a piece of TTY equipment; a TTY interface driving module communicating with a wireless communication module interface is arranged to receive data from a wireless communication module and send data from the TTY equipment to the wireless communication module; and a TTY line discipline driving module is arranged to intercept and process the data received by the TTY interface driving module from the wireless communication module and send the data after processing to the TTY logic channel driving module. By adopting the method and the device of the invention, by directly realizing the GSM0710 specification in a LINUX kernel, redundant data copying and system calling are avoided, and the system performance is improved.

Description

technical field [0001] The invention relates to electronic information products, in particular to a method and device for realizing the GSM0710 protocol in the LINUX kernel. Background technique [0002] In today's intelligent information construction, intelligent terminal equipment has been widely used in various industries. And these intelligent terminals generally have the requirement of wireless networking, so as to be able to flexibly communicate with the corresponding platform, and realize various services. [0003] Devices with wireless networking capabilities need to process (receive and send) various data streams at the same time, such as AT command streams, GPRS data streams, etc. These data streams are independent of each other. By adopting the standard multiplexing protocol defined by the GSM0710 specification, the transmission equipment is divided into multiple logical link channels to transmit these data streams at the same time. Each logical channel has an i...
