Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
VoLTE in current TD-LTE mobile communication system is end-to-end speech solution of the framework on an LTE network under the conditions of full IP.VoIP VoPs have and periodically reach, the characteristics of bag size is relatively fixed.Speech business can be spaced 20ms arrival in the activation phase, and at quiet period interval, 160ms is reached, as shown in Figure 1.Now using the mode of dynamic dispatching, it is required for SR to carry out uplink service triggering every time, substantial amounts of SR scheduling can be carried out.
In prior art, specified according to 36.321 agreements, when terminal has upstream data to need to send, need to base station transmission SR to carry out the resource bid of new data transmission, the MAC cycle of base station by interlayer interface message indicate PL carry out SR detections, if detecting SR, PL distributes transmission that certain ascending resource carry out BSR and a part of upstream data to the UE by interlayer interface message informing MAC；If being not detected by SR, PL does not notify that MAC, MAC do not carry out any scheduling yet.Now if there is SR missing inspections, voice packet can increase the time delay in a SR cycle because of dispatching, and cause user to perceive and be deteriorated.Especially in the case where load of base station is larger, SR losss can increase, and the perception of voice user can be worse.
That is, the speech business of SR detection schemes is identical with the processing mode of data service in prior art, does not consider the speech business particularity high to delay requirement, the service-aware of user can be affected in the case of SR missing inspections.When especially speech business adopts dynamic dispatching, voice packet almost all is triggered by SR, increases the dependence to SR accuracys, for this purpose, the optimization that SR detections how are carried out to speech business becomes the problem for needing to solve.
Fig. 2 shows the schematic flow sheet of the uplink scheduling request missing inspection method of the VOLTE business that one embodiment of the invention is provided, as shown in Fig. 2 the uplink scheduling request missing inspection method of the VOLTE business of the present embodiment is as described below.
201st, when the SR that UE sends is detected in base station, base station MAC layer sends interlayer interface message to PL layers, carry in the interlayer interface message for informing that whether the UE is the first information of voice user, and when the UE is voice user, also carry for informing that whether speech business is second information of activation phase；So that the PL layers are according to interlayer interface message detection SR；
If the 202, the UE is voice user, and the MAC layer receives the SR response messages that PL interlayers were sent every the SR cycles, and whether the SR that detection is carried in the SR response messages is the information of genuine SR；
In the present embodiment, PL layers determine that UE is voice user after interlayer interface message is received, and when determining that speech business is in the activation phase, if now PL layers detect SR, the SR that detection is carried in the SR response messages reported to the MAC layer when arriving in the SR cycles is the information of true SR；
If PL layers are not detected by SR, and the default SR piling moment in cycle A drives piles when arriving SR, then the SR that detection is carried in the SR response messages for reporting to the MAC layer when arriving in the SR cycles is the information of false SR；
In addition, it is necessary to explanation is：If PL layers are not detected by SR, and the default SR piling moment in cycle A does not arrive, and do not drive piles SR, then PL layers do not report SR response messages to MAC layer.
If UE is voice user, and determine that speech business is in quiet period, then SR is not detected by PL layers, and the default SR piling moment in cycle B drives piles when arriving SR, then the SR that detection is carried in the SR response messages for reporting to the MAC layer when arriving in the SR cycles is the information of false SR.
The SR piling cycles of the present embodiment can be the integral multiple in the SR cycles；It is preferred that, the SR piling cycles are same with SR cycle phases, and the SR piling cycles include：SR piling cycles A of correspondence activation phase and the SR piling cycle B of correspondence quiet period.
203rd, MAC layer distributes transmission that ascending resource carry out BSR and upstream data for UE according to the SR response messages.

In the present embodiment, PL layers are as follows for the process of voice user：It is A in piling cycle activation phase SR to arrange voice user, the span of A can be made dispatching cycle identical with SR, default setting is the cycle of SR configurations, voice user's quiet period SR piling cycle is B, the same A of span of B, dispatching cycle identical with SR, default setting is that quiet period voice packet sends cycle 160ms.
If the speech business of UE is in the activation phase, no matter SR detects whether that too drastic biopsy is surveyed, and PL reports the SR response messages that MAC detects SR, indicates whether it is genuine SR in the SR response messages when arriving in the SR cycles；
If the speech business of UE is in quiet period, if SR all only activation detections in the time of continuous quiet period SR piling cycle B, PL active reportings detect the SR response messages of SR, the SR of vacation are designated as in the SR response messages to MAC.
It should be noted that UE to base station send SR when, if sent together with SR and ACK, CQI etc., situation of the base station side for list frame scheduling ACK+SR, the ACK contents that vacation SR is carried in not affecting the message in the SR response messages that PL layers are reported；
Situation of the base station side for list frame scheduling CQI+SR, in the SR response messages that PL layers are reported, vacation SR is reported and CQI can be caused to report.For this purpose, the SR response messages that PL layers are reported in only activation detection in the present embodiment carry the information of false SR.
The method of the present embodiment can make SR still can dispatch out voice packet in the case of missing inspection in time, it is ensured that the time delay of voice packet, improve voice quality, while not affecting on data user.
