Description
Technical field
The present invention relates to a kind of standby wakeup method, especially a kind of standby wakeup method based on tdma system. Belong toWireless communication technology field.
Background technology
Along with the development of wireless control technology and business, the needed function of wireless terminal device is also more and more. In various nothingsIn line communication system, conventionally all adopt TDMA(TimeDivisionMultipleAccess, time division multiple acess) system, timeDivide multiple access to refer to that becoming each frame of periodic frame (Frame) to be divided into several time slots time division sends to base station againSignal, is meeting under timing and synchronous condition, base station can in each time slot, receive respectively each mobile terminal signal andNot mixed disturbing. Meanwhile, the signal that base station is sent to multiple mobile terminals is all arranged in order to give in fixed time slot and transmits, each movementTerminal as long as receive in the time slot of specifying, and in the signal on Jiu Nenghe road, handle is issued its signal distinguishing and receives.
At wireless communication field, hand-held Terminal Type equipment is limited to battery factor, often need in the time of standby, enter power save mode,To maintain lower power consumption. Energy-conservation have a various ways, and wherein a kind of power save mode is intermittent duty, and communicating terminal is being treatedWhen machine, other function device is closed, and only maintains the break-make of receiving function, opens and receives a period of time, closes while receiving one sectionBetween, move in circles. Opening in time of reception, if receive certain specific type wireless signal, be referred to as to wake up mark at every turn,Equipment is waken up, and enters normal operating conditions; Wake mark up if terminal device is not received, close and connect to certain hourReceive, reenter sleep state.
In radio digital communication, waking mark up is a kind of specific bit sequence, and launch terminal is in the normal communication of transmissionBefore appearance, first send one and wake mark up, to wake receiving terminal up. Under the energy saver mode of intermittent duty, especiallyIn tdma system, launch terminal is interrupted transmitting, therefore has the problem of waking hit rate up, in order to ensure waking up,Often need to repeat to send multiple marks that wake up.
Summary of the invention
