TA orders are sent in duration section in section, otherwise, stop sending TA orders.
In the step of above-described embodiment, when TATimer timing length is long less than DRX cycle, base station passes through the
Two counters record the second time span that terminal is under inactive state, in the second time span are more than the second threshold value
In the case of, base station send TA orders the step of can include：Base station judges the state of terminal, wherein, when terminal is from inactive
When state enters active state, base station sends TA orders in the case where the second time span is more than the second threshold value；Work as terminal
When being constantly under active state, if TATimer timing length time-out, base station sends TA orders.
Preferably, sending the step of TA orders in above-described embodiment in the duration can include：Judge that the duration determines
When device whether reach start the time, wherein, reach start the time in the case of, base station send TA orders.
It can be seen from above-described embodiment, in implementation process, base station dispatcher knows the DRX configuration parameter of terminal, can
According to DRX configurations and terminal up-downgoing dispatch situation, DRX associated timer operation conditions is calculated, and know that terminal is
It is no to be in the DRX activity times.Scheduler is needed to safeguard two counters to each UE for being configured with DRX, and respectively UE is not adjusted
Degrees of data time counter, UE are in DRX inactive time counters.UE does not dispatch the effect of data time counter and is：
If UE does not have data dispatch (exceed using the timer and set threshold value as basis for estimation) within the quite a while, can recognize
Small for UE data volumes, base station side Maintenance free UE uplink synchronous (can so save system resource), UE can pass through when necessary
Again access way obtains synchronous.UE is in the effect of DRX inactive times counter and is：When base station sends TA order timers
When duration is less than DRX cycle, it is impossible to ensure in the TA order timer expiry times, have an onDurationTimer operation
Chance, namely cannot be guaranteed UE can be in the DRX activity times.To make TA orders have an opportunity to send, base station is entered every time in UE
Judged when entering DRX active states, if UE is in DRX inactive times counter and is more than setting threshold value, then it is assumed that TA
The soon overtime possibility of order timer is bigger, it is necessary to issue TA orders at this moment.
