Embodiment
Key idea of the present invention is: when terminal is in descending active period, the base station dopes terminal, and to be in the probability of up quiet period big, thus, the base station discharges the ascending resource of allocating in advance to this terminal that continues, if terminal will send upstream data in descending active period, then terminal needs to send " ascending resource request for allocation " to base station application ascending resource; When terminal is in descending quiet period, the probability that base station prediction terminal is in up active period is big, thus, the base station is allocated lasting ascending resource in advance for this terminal, if terminal does not have upstream data to send in descending quiet period, then terminal needs transmission " ascending resource discharges request " to come the requirement base station that preallocated ascending resource piece is discharged.Scheduling for downlink resource is similar with it, so locate to repeat no more.
Technical scheme of the present invention comprises following steps as shown in Figure 5:
The resource allocation of step 502, change downlink or uplink direction.
Hereinafter will introduce the scheduling scheme of ascending resource, for the scheduling of downlink resource scheduling scheme with reference to ascending resource.
As shown in Figure 6, be specific embodiment of the invention uplink scheduling method flow chart, specifically comprise:
Step 601: the downlink data transmit status of terminal is at first judged and write down in the base station: i.e. quiet period or active period;
Step 602: base station waits time T;
Step 603: the base station judges whether the downlink data transmit status of current terminal change has taken place, if do not change, returns step 602; If change has taken place, enter step 604;
Step 604:, then enter step 605 if the downlink data transmit status of terminal has changed quiet period over to by active period; Otherwise,, then enter step 606 if the downlink data transmit status of terminal has changed active period over to by quiet period;
Step 605: the resource requirement according to active period is a terminal continuous dispatching ascending resource, and by downlink signaling notice terminal ascending resource scheduling mode change has taken place; Return step 602.
Step 606: the resource requirement according to quiet period is a terminal continuous dispatching ascending resource, and by downlink signaling notice terminal ascending resource scheduling mode change has taken place; Return step 602.
Need to prove: stand-by period T can come definite according to giving out a contract for a project of business at interval, as: for the VoIP business, because the transmission time interval of the downlink data packet of its active period is 20ms, then T can be set to 20ms.
As from the foregoing, the transfer point of downlink data transmit status is determined in the base station: comprise that the downlink data transmission sends the transfer point that is transferred to active period by quiet period by transfer point and the downlink data that active period transfers quiet period to.Transfer point in the downlink data transmit status, the base station is that terminal is allocated lasting ascending resource in advance and notified terminal by downlink signaling, be specially: when the downlink data transmission transfers quiet period to by active period, the base station sends one " ascending resource continuous dispatching message " and gives terminal, simultaneously, the base station is a terminal continuous dispatching ascending resource by the resource requirement (comprising resource size and frequency) of active period; When the downlink data transmission transferred active period to by quiet period, the base station sent one " ascending resource continuous dispatching cancellation message " and gives terminal, and simultaneously, the base station is a terminal continuous dispatching ascending resource by the resource requirement (comprising resource size and frequency) of quiet period.
