Description
Technical field
The present invention relates to the mobile communication technology field, be specifically related to a kind of method of sense terminals high-speed moving state.
Background technology
In moving communicating field, terminal is carried out information interaction with wireless mode and base station, and the position of terminal itself can be moved.In order to improve communication quality better, be in the terminal in moving, need not stop to detect the mobile status of self, and, adjust the various parameters relevant with mobile status according to detected mobile status.At GSM, time division duplex-low spreading rate (TDD-LCR, Time Division Duplexing-LowChip Rate) and Long Term Evolution (LTE, Long Term Evolution) etc. in the mobile communication system, judge that the principle that terminal enters high-speed moving state is:
If at T
CRmaxTime period, the number of times of sub-district gravity treatment/switching has surpassed N
CR_H, terminal enters high-speed moving state.Here, the number of times of described sub-district gravity treatment/switching is meant that the number of times sum of sub-district gravity treatment and sub-district switching takes place terminal.
If terminal is in the high-speed moving state, the principle that the judgement terminal withdraws from high-speed moving state is: at T
CRmaxTime period, sub-district gravity treatment/switching times no longer surpasses N
CR_H, judge that terminal does not meet the high-speed moving state criterion, but continue to keep high-speed moving state; Up to lasting T
CRmaxhystTime detects terminal always and does not all meet the high-speed moving state criterion, judges that then terminal withdraws from high-speed moving state, enters normal mobile state.
Above-mentioned parameter T
CRmax, N
CR_HAnd T
CRmaxhystEqual system messages that issues from the sub-district.
In the prior art, use duration to be T
CRmaxTime window the terminal mobile status is detected: the sub-district gravity treatment that takes place in this time window and the number of times of switching have surpassed N
CR_H, judge that then terminal has entered high-speed moving state.In the above-mentioned detection method with T
CRmaxTime window is that unit detects, be easy to cause the judgement time-delay, promptly can not in time judge terminal and enter high-speed moving state, and then also just can not immediately impose relevant parameter, thereby also just not reach the purpose that high-speed mobile detects the terminal in the high-speed mobile.
Fig. 1 shows the schematic diagram of prior art sense terminals mobile status.Three transverse axis among Fig. 1 all are the gravity treatment of representing detected terminal mobile status, time and terminal respectively/switching time points.As shown in Figure 1, in the time period of t0～t1, suppose that the gravity treatment/switching times accumulative total of terminal surpasses N
CR_H, promptly at t1 constantly, terminal has entered high-speed moving state; Because prior art is with T
CRmaxTime window is a unit, and (time difference is T to needs between t0 and the t2 constantly to t2
CRmax), could judge that terminal has entered high-speed moving state, therefore, the above-mentioned determination methods of prior art causes when the mobile status of sense terminals easily judges time-delay, can not detect the mobile status of terminal reality immediately, exactly.
