Problems solved by technology

Because the start, stop, and timeout of the timer all require message interaction with the timer task, which requires the scheduling of the operating system, which invisibly increases a lot of system overhead, and at the same time brings a great negative effect on the operating efficiency of the RLC task. influences
As a result, the performance of the terminal protocol stack software system is reduced, and the data transmission rate cannot reach a higher level.

Embodiment Construction

[0021] First of all, the scope of application of the present invention is described: the present invention is applicable to various wireless communication systems, including systems such as GSM / GPRS / EGPRS systems, TD-SCDMA systems and WCDMA; its corresponding terminals use various terminal protocol stack software and systems For communication, the GPRS protocol in the GSM / GPRS system is only one of them, and the terminal protocol stack software of other wireless communication systems is also suitable for the present invention (including the EGPRS protocol, which is the same as GPRS in the protocol framework).

[0022] Second step, explain the working principle of the present invention:

[0023] (1) In the terminal protocol stack software, set the overtime value of each timer that needs to be managed and the data structure of the timer queue, and modify the start and stop functions of the timer. The modified function does not need to send messages to the timer module task, but ...

Abstract

The invention relates to one terminal wireless communication agreement stack software timer management method, which comprises the following steps: setting needed timer super value and timer queen data structure and when the timer is started, according to the started system frame number and relative super value computing the super value; the timer computes whether to process on super time result according to the physical layer message frame number and super time value. The invention uses timer queen to take place of timer module.

Description

technical field [0001] The invention relates to a communication terminal, in particular to a method for managing a terminal wireless communication protocol stack software timer. Background technique [0002] When designing and implementing the wireless communication protocol stack in the embedded system software, we need to use the timer module to manage the timer unit Timer specified in the wireless communication protocol. The timer module usually uses the interrupt or crystal oscillator of the embedded system to measure time, and after the set hardware counter time arrives, it notifies the task to which the relevant timer belongs to perform corresponding timer timeout processing. The timer is a very important data structure in the protocol stack, basically every protocol module has a corresponding timer unit. The operating system used by the terminal protocol stack software regards the timer module as a task. Every time a timer unit of a certain protocol stack task is sta...
