Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
In embodiments of the present invention, the base station is that the UE configuration has the up persistent scheduling resource of some cycles, and the subframe that has disposed available up continuous dispatching for UE is called the chance point.In the embodiment of the invention, the base station resource release conditions is set, when satisfying the base station resource release conditions, the base station discharges up persistent scheduling resource, and UE resource release conditions is set, and when satisfying UE resource release conditions, UE discharges up persistent scheduling resource.The base station resource release conditions comprises: BS receives resource from UE and releases order the number of times of acknowledge message when reaching number of times that pre-determined number, BS receive the voice interruption indication continuously and reaching number of times thresholding, BS timer timing arrives; UE resource release conditions is: UE receives that resource from the base station releases order, UE is continuously when the chance point detects IP-based speech data VoIP and sends buffering area for empty number of times thresholding, UE timer timing arrives.Above-mentioned base station resource release conditions and UE resource release conditions can be carried out combination in any, and are bonded to the concrete scheme that resource discharges in the communication system.Below will the preferred embodiment that resource discharges be described in detail.
Be illustrated in figure 1 as the sketch map of first embodiment of the invention.Up persistent scheduling resource period Tn is made as 20ms (millisecond), and UE is provided with timer T11, and duration is made as 50ms, and the base station is provided with timer T12, and duration is made as 90ms more than or equal to the duration of UE.HARQ (mixing automatic repeat requests, Hybrid Automatic Retransmission Request) sends 4 sub-frame that are spaced apart with feedback, feedback and re-transmission, and the HARQ maximum transmission times is 3.
UE has the VoIP data to need to send, and the base station in subframe # 2 for UE has disposed available up persistent scheduling resource, then subframe # 2 is the chance point, UE sends the VoIP data to the base station in subframe # 2;
The base station has disposed available up persistent scheduling resource for UE in subframe # 2; But do not receive the VoIP data; Also do not receive data or other data higher than this VoIP data priority, hence one can see that in the base station takes defeat at this chance point, then starts timer T12; And to UE transmission NACK (Non-Acknowledgement, non-affirmation) message and mandate re-transmission resource;
After UE receives this NACK message,, the next one resends this VoIP data in having the subframe #10 of available ascending resource;
These VoIP data are received in the base station in subframe #10, stop (stop) timer T12, and in subframe # 14, send ACK (Acknowledgement confirms) message;
At next chance point, promptly among the subframe # 22, the base station is that UE has disposed available up persistent scheduling resource; At this moment; UE detects VoIP and sends buffering area for empty, and the VoIP data that promptly need not send have only the data lower than VoIP data priority to need to send; Then UE starts timer T11, and sends more lower-priority data to the base station;
The base station receives the data that are lower than VoIP priority in subframe # 22, learn the VoIP data that UE need not send, and then thinks to receive the voice interruption indication, starts timer T12, and sends ACK message;
At follow-up chance point; Be among subframe # 42 and the subframe # 62; UE has no data to need to send, and then UE sends empty BSR to the base station in subframe # 42 and subframe # 62, when timing (50ms) arrival of the timer T11 of UE; UE discharges up persistent scheduling resource, does not promptly re-use subframe #71 up persistent scheduling resource afterwards.Need to prove that above-mentioned empty BSR comprises VoIP buffering area among the UE and is empty indication, promptly indicate VoIP and send buffering area for empty, also like this at other embodiment of the present invention, repeat no more.
The base station receives empty BSR respectively in subframe # 42 and #62, learn the VoIP data that UE need not send, and thinks and receives the voice interruption indication, and then the base station is received 3 voice interruption indications continuously.
A kind of computational methods of preferred number of times thresholding are that the number of times thresholding in the present embodiment receives that at chance point the number of times of voice interruption indication reaches the number of times thresholding when the base station for
continuously for
; Then the base station is released to the up persistent scheduling resource of this UE configuration; And termination timing device T12, in follow-up subframe (like subframe #66), send ACK message and give UE.
In the present embodiment, the base station has guaranteed that to the judgement and the timing mechanism of voice interruption indication UE and base station can in time discharge up persistent scheduling resource.
It will be appreciated by those skilled in the art that the base station can receive after voice interruption indication reaches the number of times thresholding continuously, is released to the up persistent scheduling resource of this UE configuration.The base station also can be released to the up persistent scheduling resource of this UE configuration receiving continuously to wait for a period of time after voice interruption indication reaches the number of times thresholding again, and does not exceed invention scope of the present invention.
Need to prove; ACK message in the present embodiment and NACK message can be separate message, also can be included in other message, for example; The affirmation message of mixing automatic repeat requests (HARQ); The control messages of Radio Resource control (RRC) layer etc., also like this in other embodiment of the present invention, repeat no more.
Second embodiment of the invention is similar with first embodiment; Difference is that UE detects VoIP transmission buffering area when chance point subframe # 42 have the VoIP data, then UE termination timing device T11; And send the VoIP data at this chance point and give the base station; When the base station receives this VoIP, termination timing device T12, and send ACK message and give UE.
Be illustrated in figure 2 as the sketch map of third embodiment of the invention.Up persistent scheduling resource period Tn is made as 20ms, and UE is provided with timer T21, and duration is made as 50ms, and the base station is provided with timer T22, and duration is not less than the duration of UE, is made as 90ms.HARQ sends 4 sub-frame that are spaced apart with feedback, feedback and re-transmission, and the HARQ maximum transmission times is 3.
Present embodiment is similar with first embodiment; Difference is; The base station does not receive UE and retransmits the empty BSR that sends among resource place subframe # 70 and the subframe # 78 at chance point subframe # 62 and HARQ, and then 2 voice interruption indications are only received continuously in the base station on chance point and corresponding HARQ instance re-transmission resource, do not reach the number of times thresholding; Can not discharge up persistent scheduling resource, but in subframe #66, #74 and #82, send NACK message to UE;
UE reaches HARQ transmission maximum times 3 after subframe #82 receives NACK message, the transmission that then stops this empty BSR is attempted;
At subframe # 22 to (before being the T22 timing arrives) between the subframe #111; The base station does not receive the VoIP data; And the voice interruption indication that on chance point and corresponding HARQ instance re-transmission resource, receives does not continuously reach the number of times thresholding yet; Then the base station discharges up persistent scheduling resource when timer T22 timing arrives.
In the present embodiment, the base station has guaranteed that to the judgement and the timing mechanism of voice interruption indication the base station under the situation of empty BSR bust this, can in time discharge up persistent scheduling resource.
Be illustrated in figure 3 as the sketch map of fourth embodiment of the invention.Up persistent scheduling resource period Tn is made as 20ms; The base station is provided with timer T31; Duration is made as 90ms; And the base station is set receives 3 voice interruption indication back continuously and send and release order, it is 2 that the number of times thresholding is set, promptly the base station discharges up persistent scheduling resource after to the ACK message that releases order receiving 2 times continuously.HARQ sends 4 sub-frame that are spaced apart with feedback, feedback and re-transmission, and the HARQ maximum transmission times is 3.
UE sends the VoIP data at chance point (being subframe #2) and gives the base station; The base station does not receive any data in subframe # 2, then start timer T31, and sends NACK message and authorize the re-transmission resource to UE;
After UE receives this NACK message, in the re-transmission resource subframe #10 that authorizes, resend this VoIP data; These VoIP data are received in the base station in subframe #10, termination timing device T31, and in subframe # 14, send ACK message;
UE has only the data lower than VoIP data priority to need to send in the VoIP data that chance point (being subframe #22) need not send, and then UE sends more lower-priority data to the base station; The base station receives the data that are lower than VoIP priority in subframe # 22, then think and receive the voice interruption indication, starts timer T32, and sends ACK message;
UE still has no data to need to send at chance point (being subframe #42), and then UE sends empty BSR and gives the base station in subframe # 42; The base station does not receive empty BSR in subframe # 42, then send NACK message to UE, and UE re-transmission empty BSR is carried out resource authorization; Terminal UE receives NACK message and authorizes the back to retransmit empty BSR with retransmitting.The base station thinks to receive the voice interruption indication that at this empty BSR that subframe #50 receives re-transmission transmission ACK message is given UE;
UE still has no data to need to send at chance point (being subframe #62), and then UE sends empty BSR to the base station in subframe # 62; The base station receives this empty BSR in subframe # 62, think to receive the voice interruption indication, then sends ACK message and gives UE;
The base station has retransmitted in chance point and corresponding HARQ instance thereof and has received 3 voice interruption indications on the resource continuously, and then the resource Releasecmd message that releases order is sent to UE in the base station in subsequent subframe (like subframe #70);
UE does not receive this Release cmd message in subframe # 70, then in subframe #74, send NACK message to the base station; Because channel quality is relatively poor, this NACK message is made mistakes in transmission, and the base station receives ACK message;
The base station is sent Release cmd message once more and is given UE in subsequent subframe # 78, after UE receives this message, discharge up persistent scheduling resource, and sends ACK message at subsequent subframe #82 and give the base station; The base station receives this ACK message, and then the base station receives UE to the affirmation message that resource releases order continuous 2 times, reaches the number of times thresholding, and the base station is released to the up persistent scheduling resource of this UE configuration, and termination timing device T31.
In the present embodiment, when UE receives releasing order that the base station sends, discharge up persistent scheduling resource, and the base station discharges up persistent scheduling resource when receiving 2 UE to the affirmation of releasing order continuously.Therefore, present embodiment issues through releasing order and confirms, can provide UE to receive the reliability that releases order, thereby avoids being discharged by the resource that the affirmation transmission of messages failure of releasing order causes the collision problem of mistake and redistribute resources.
It will be appreciated by those skilled in the art that the base station receives m voice interruption indication back continuously and sends and release order to UE, the base station can receive continuously n UE to the affirmation of releasing order after, be released to the up persistent scheduling resource that this UE disposes.Wherein, m and n can be any positive integer, and specifically value can be confirmed according to factors such as carrier policy, channel quality, quality of services, and does not exceed invention scope of the present invention.
Be illustrated in figure 4 as the sketch map of fifth embodiment of the invention.Up persistent scheduling resource period Tn is made as 20ms; The base station is provided with timer T41; Duration is made as 90ms; And the base station is set receives 3 voice interruption indication back continuously and send and release order, and the number of times thresholding is set is 2, promptly the base station discharges up persistent scheduling resource after to the affirmation ACK message that releases order receiving 2 times continuously.HARQ sends 4 sub-frame that are spaced apart with feedback, feedback and re-transmission, and the HARQ maximum transmission times is 3.
Present embodiment is similar with the 4th embodiment, and difference is that UE sends empty BSR to the base station in subframe # 62, and the base station does not receive this empty BSR in subframe # 62, therefore send NACK message to retransmit resource for UE and mandate; UE resends empty BSR and still fails in follow-up subframe # 70 and subframe # 78; Then this message reaches HARQ maximum transmission times 3; UE no longer continues it is sent trial; Simultaneously, the number of times that the base station receives voice interruption indication continuously resets to 0, and promptly the base station is thought and received 0 voice interruption indication continuously;
UE still has no data to need to send at follow-up chance point (being subframe #82 and subframe #102), and therefore, UE sends empty BSR in subframe #82 and subframe # 102, and receives the ACK message of base station.At this moment, the base station receives 2 voice interruption indications continuously;
The base station at subframe # 22 to (before being the T41 timing arrives) between the subframe #111; The base station does not receive the VoIP data; And the voice interruption that receives continuously indication does not reach 3 times yet, and then the base station is sent resource and released order Release cmd message to UE when timer T41 timing arrives;
UE discharges up persistent scheduling resource after receiving this Release cmd message, and sends ACK message to the base station;
After the base station receives this ACK message, in subsequent subframe, send Release cmd message once more and give UE, and after the ACK message that receives the UE feedback, reach the number of times thresholding, be released to the up persistent scheduling resource of this UE configuration.
In the present embodiment, the timing mechanism of base station has guaranteed the base station under the situation of empty BSR bust this, can initiatively initiate the resource dispose procedure according to detecting, and avoids discharging the untimely wasting of resources that causes of up persistent scheduling resource.
