Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
The basic design of the method for the invention is: network side is receiving that the LTE terminal is after the business transmission service request of its transmission, the up logic channel that is used for business data transmission according to this request for above-mentioned LTE terminal configuration N bar, and configuration result is handed down to the LTE terminal, wherein, the configuration information (comprising precedence information) that comprises the up logic channel of this N bar in the configuration result; After the LTE terminal is received, if judging in the up logic channel of this N bar has the priority of the up logic channel of M bar identical, then after the uplink authorization resource that obtains the network side distribution, successively the up logic channel of above-mentioned N bar is dispatched transmission according to priority order from high to low, and when being dispatched to the up logic channel of above-mentioned M bar, from the up logic channel of this M bar, choosing the logic channel that is not scheduled in the last scheduling process and carry out the priority scheduling transmission prior to the up logic channel of other M-1 bar.Wherein, N 〉=M 〉=2.
The LTE terminal can be dispatched transmission to the up logic channel of this M bar according to any order when being dispatched to the up logic channel of above-mentioned M bar first, until the up logic channel of this M bar has all been dispatched or the uplink authorization resource is used up.
Preferably, the LTE terminal can be the up logical channel assignment dispatching sequence of this M bar when the priority of judging the up logic channel of above-mentioned M bar is identical; When being dispatched to the up logic channel of this M bar each time, this LTE terminal can be dispatched successively according to current dispatching sequence and be sent the up logic channel of this M bar, up to the uplink authorization resource use up or the up logic channel of this M bar all scheduling finish (if authorization resources is enough, may send the total data on the up logic channel of M bar, if authorization resources is not enough, also may only send the partial data on the most forward up logic channel of dispatching sequence).After this finishing scheduling, the LTE terminal can be readjusted the dispatching sequence of the up logic channel of above-mentioned M bar, and the adjustment mode can adopt any one in the following dual mode:
Mode one:
After the dispatching sequence of the logic channel dispatched in the up logic channel of this M bar placed the logic channel of not scheduling.Owing to before the dispatching sequence of this logic channel that is not scheduled is positioned at the logic channel of having dispatched, can guarantee that then this logic channel that is not scheduled can preferentially be scheduled in the scheduling next time.
For example: 4 up logic channels that priority is identical: A, B, C, D, and the initial schedule of LTE terminal distribution order also be A, B, C, D}, promptly channel A can be scheduled at first, D is scheduled at last.If in this scheduling process, only dispatched A and B, then after scheduling is finished, according to mode one, the dispatching sequence of A and B must be placed the back of C and D, as adjusted dispatching sequence be: { C, D, A, B}, then in next scheduling process, dispatch, can guarantee that channel C and D can be by priority schedulings according to this adjusted dispatching sequence.
Mode two:
Last position is put in the dispatching sequence's adjustment that dispatching sequence in the up logic channel of this M bar is positioned at primary up logic channel.
For example: 4 up logic channels that priority is identical: A, B, C, D, and the initial schedule of LTE terminal distribution order also be A, B, C, D}, promptly channel A can be scheduled at first, D is scheduled at last.As shown in Figure 1, if only dispatched A and B in this scheduling process, then after scheduling is finished, according to mode two, the dispatching sequence of A must be placed the back of D, promptly adjusted dispatching sequence is: { B, C, D, A}.According to this kind adjustment mode, make that each bar in the up logic channel of M bar can both impartial acquisition have precedence over the chance that the up logic channel of other (M-1) bar is scheduled.
In addition, can also carry out scheduling controlling to the up logic channel of above-mentioned M bar in the following way:
The LTE terminal can be the up logical channel assignment dispatching sequence of this M bar when the priority of judging the up logic channel of above-mentioned M bar is identical; When being dispatched to the up logic channel of this M bar the i time,, then the up logic channel that the dispatching sequence is in the j position is carried out priority scheduling at this if the value of i is not equal to the integral multiple of M; If the value of i equals the integral multiple of M, then the up logic channel that the dispatching sequence is in the M position is carried out priority scheduling at this, can dispatch according to the dispatching sequence the up logic channel of other M-1 bar then, exhaust until intact up logic channel of M bar of whole scheduling or uplink authorization resource.Wherein, the value of j equals the mould of i and M, i.e. j=imodM, and i is a positive integer.For example, article 4, the identical up logic channel of priority: A, B, C, D, and the initial schedule of LTE terminal distribution order also is { A, B, C, D}, then when the 4th is dispatched to the up logic channel of this M bar, priority scheduling channel D, when the 5th is dispatched to the up logic channel of this M bar, priority scheduling channel A.
Further be illustrated with an application example of the present invention below.
The LTE terminal is after network side requested service transmission service, and network side is the up logic channel of terminal configuration N bar, and has many up logic channels that priority is identical in the up logic channel of this N bar.As shown in Figure 2, when carrying out the uplink scheduling transmission, the MAC layer of the LTE protocol stack in the LTE terminal carries out following processing:
1) according to the priority of logical channels of network configuration, the up logic channel of N bar to configuration sorts from high to low, logical channel number after the ordering first is kept at array abConfigLogchId[N successively] in, as shown in Figure 3, wherein the M of an equal priority logic channel (comprise M1, M2,---, MM) sequencing determine at random;
2) after the MAC layer is received the up transmission indication that physical layer reports, make counting variable i=0;
3) whether judge remaining uplink authorization resource greater than 0, if, then scheduling to send logical channel number be abConfigLogchId[i] logic channel on data; Otherwise execution in step next step;
4) judge the logic channel abConfigLogchId[i of this scheduling] whether be the logic channel (whether the value of promptly judging i equals 0) of first scheduling, and with the preceding once logical channel number of scheduling is abConfigLogchId[i-1] the priority of logic channel whether identical, if i is not equal to 0 and inequality with previous priority, then exchange the element abConfigLogchId[i among the array abConfigLogchId] and abConfigLogchId[i-1] value; Otherwise, carry out next step;
5) make counting variable i add 1;
6) judge whether not intact N the logic channel (whether the value of promptly judging i is less than N) of poll, if then forward step 3 to, otherwise forward step 2 to.
A plurality of logic channels that the present invention has provided All factors being equal, preference will be give to level carry out the concrete dispatching method that uplink scheduling sends, can simply, effectively realize 3GPP 36321 agreements regulations to All factors being equal, preference will be give to a level logic channel, the demand of equal service should be provided, thereby better meet the demand of client a plurality of voice and packet data concurrent service services.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
