Embodiment
Embodiment of the present invention network equipment determines the target UE activating low deferred traffic; For the low deferred traffic transport layer of described target UE distributes specific transfer resource, sent by pre-assigned described specific transfer resource when there being low deferred traffic to make described target UE.The low deferred traffic transport layer being the target UE activating low deferred traffic due to embodiment of the present invention network equipment allocates specific transfer resource in advance, thus shortens the wait time delay of sparse burst service transmission;
Further, the embodiment of the present invention can also improve system spectral resources utilance, be conducive to operator's existing cellular network while support traditional business, the support of superposition to low deferred traffic transfer function, reduce carrier network upgrade cost, greatly accelerate the support of existing carrier network to low delay transport service.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As shown in Figure 1, the system of the embodiment of the present invention one business transmission comprises:
Network equipment 10, for determining the target UE activating low deferred traffic; For the low deferred traffic transport layer of described target UE distributes specific transfer resource, sent by pre-assigned described specific transfer resource when there being low deferred traffic to make described target UE;
Activate the target UE 11 of low deferred traffic, for determining the pre-assigned specific transfer resource for low deferred traffic transport layer of network equipment; After having low deferred traffic packet to arrive, send low deferred traffic packet by pre-assigned described specific transfer resource.
Preferably, for improving spectrum utilization efficiency, the described network equipment of the embodiment of the present invention is specific transfer resource, the transfer resource multiplexing identical time that the general service transport layer being his subscriber equipment with described network equipment is distributed and the frequency resource of the low deferred traffic transport layer distribution of described target UE.
Wherein, " low deferred traffic transport layer " and " general service transport layer " are two kinds of separate RAT (wireless access type), and therefore both are at frame structure, and the aspects such as synchronization scenario can be completely independently.
Such as " low deferred traffic transport layer " can be similar to the 802.11 Non-alignment Frame structures that existing local area network (LAN) extensively adopts, and also can be the novel short frame structure for Future cellular networks; And " general service transport layer " can be existing LTE access net system." low deferred traffic transport layer " identical eat dishes without rice or wine running time-frequency resource multiplexing with " general service transport layer ", and network equipment needs to possess the ability of two kinds of dissimilar signals being carried out to demodulation, and subscriber equipment can be supported " low delay transport layer " and " general service transport layer " two kinds of access waies simultaneously simultaneously.
Except aforesaid way, it is collaborative that " the low deferred traffic transport layer " and " general service transport layer " of the embodiment of the present invention also can carry out to a certain degree, be included in modulation and compile coding scheme design, and frame structure and frame synchronization aspect, base station transceiver design complexities can be reduced like this, reduce " low deferred traffic transport layer " impact on " general service transport layer ".
When transmitting, the frame structure that low deferred traffic transport layer can be consistent with general service transport layer can be also completely separate frame structure.That is, described target UE transmits the frame structure that low deferred traffic uses on described specific transfer resource, and on described specific transfer resource, transmit the frame structure that general service uses identical or different with other subscriber equipmenies described.Be introduced respectively below.
The frame structure that situation one, low deferred traffic transport layer and general service transport layer are consistent, specifically see Fig. 2.
Wherein, low deferred traffic is owing to being sparse transmission, and therefore during low deferred traffic transport layer transmission, the actual running time-frequency resource ratio taken is very low; And general service layer is owing to having converged a large amount of general service (such as voice, Streaming Media, word class business), therefore general service transport layer has been transmitted utilizing all obtainable running time-frequency resources.
In order to reduce influencing each other between low deferred traffic transport layer and general service transport layer, one preferably mode is:
Described network equipment adjusts the uplink transmission time lead of low deferred traffic transport layer and general service transport layer respectively, minimally synchronous between transmission unit when arriving described network equipment to make the data of low deferred traffic transport layer and general service transport layer.
Network equipment is by adjusting low deferred traffic transport layer and general service transport layer uplink transmission time lead, when ensureing that the data of low deferred traffic transport layer and general service transport layer arrive network equipment, minimally phase mutually synchronization (angle that is, between low deferred traffic transport layer and general service transport layer, minimum transmission units receives from network equipment is completely overlapping) between transmission unit.
The frame structure of situation two, low deferred traffic transport layer and general service transport layer is separate, specifically see Fig. 3.
Wherein, low deferred traffic is owing to being sparse transmission, and therefore during low deferred traffic transport layer transmission, the actual running time-frequency resource ratio taken is very low.In addition low delay transport layer can adopt and carry out based on the method for synchronization frame format that sends; Also can adopt and carry out based on asynchronous system the frame format that sends.
Because the frame structure of low deferred traffic transport layer and general service transport layer is separate, therefore network equipment does not need the coordination low deferred traffic transport layer and general service transport layer being carried out to any synchronization aspects.
In force, after subscriber equipment activates low deferred traffic, low deferred traffic transmission configuration process can be triggered.
In low deferred traffic transmission configuration process, network equipment is that the low deferred traffic transport layer of described target UE (activating the subscriber equipment of low deferred traffic of living) distributes specific transfer resource.
After uplink business data bag is committed to the transport layer of subscriber equipment from the high level of subscriber equipment, uplink business data bag is directly sent to network equipment by pre-assigned described specific transfer resource by subscriber equipment, and detailed process can see Figure 13.
In force, if the low deferred traffic of described target UE deexcitation, described network equipment is released to the described specific transfer resource that described target UE distributes.
Concrete, when after the low deferred traffic of target UE deexcitation, trigger low deferred traffic transmission configuration dispose procedure.
In dispose procedure, the specific transfer resource distributing to target UE is discharged in resource pool by network equipment again, and the target UE activating low delay transmission configuration to other for subsequent allocations uses, and detailed process can see Figure 14.
Due to inner in low delay transport layer, for not mutually orthogonal situation may appear in the resource of different target user equipment allocation, so the situation about colliding of low delay transport layer inside can be there is.In order to less collision situation occurs, embodiments provide three kinds of processing modes, be introduced respectively below.
Mode one, network equipment are that the uplink of different subscriber equipment distributes completely orthogonal transfer resource, in this case, meet completely orthogonal between two between the specific transfer resource that different target UEs transmits low delay transport layer data, specifically can see Fig. 4.
Concrete, if the quantity of described target UE is not more than the quantity of the specific transfer resource that system can be distributed, described network equipment is that different described target UEs distributes completely orthogonal specific transfer resource.
Mode two, in force, under the sum of system access target UE is greater than the configurable orthogonal specific transfer resource situation of system, network equipment can be chosen as new target UE, distributes a transfer resource distributed, specifically can see Fig. 5.
Concrete, if the quantity of described target UE is greater than the quantity of the specific transfer resource that system can be distributed, described network equipment distributes the specific transfer resource having distributed to target UE described in other for described target UE.
May collision be there is in the uplink between the target UE of multiplexing identical orthogonal specific transfer resource in this case, network equipment can by the orthogonal specific transfer resource being the multiplexing low delay of target UE that low delay utilization ratio of transmission resources is low, to lower the probability that collision occurs, improve transmission reliability, when configuring the orthogonal specific transfer resource of the multiplexing identical low delay of different target UEs, consider different target UE business data packet characteristic effusive-flow time, the target UE that the overlapping probability of business data packet due in can be made minimum forms resource multiplex.
That is, described network equipment distributes for described target UE the specific transfer resource having distributed to target UE described in other, comprising:
Described network equipment determines the capacity occupancy of each specific transfer resource distributing to target UE described in other;
Described network equipment is the specific transfer resource that described target UE partition capacity occupancy is minimum.
In force, if need multiplexed resource, a specified threshold can being set, the low deferred traffic collision probability on specific transfer resource can be controlled, in rational level, also can ensure systematic function by rationally arranging thresholding like this.
Concrete, if need multiplexing, after judging whether there is the described target UE of receiving in the capacity occupancy of each specific transfer resource, capacity occupancy is not more than the specific transfer resource of specified threshold, if had, then distribute specific transfer resource for new target UE; Otherwise, refuse as new target UE distributes specific transfer resource.
In force, under the sum of system access target UE is greater than the configurable orthogonal specific transfer resource situation of system, network equipment can be chosen as new target UE and distribute non-orthogonal transfer resource, be new target UE, distribute a transfer resource distributed
Concrete, when described network equipment is different described target UE distribution non-orthogonal specific transfer resource, described network equipment determines the capacity occupancy of each specific transfer resource distributing to target UE described in other; The capacity occupancy of the specific transfer resource that described target UE needs, and the capacity occupancy of each specific transfer resource, for different described target UEs distributes non-orthogonal specific transfer resource.
In force, mode one and mode two can be combined:
1, suppose that current area has 10 groups of distributable orthogonal specific transfer resources, network equipment is when needing to distribute orthogonal specific transfer resource for new target UE, first the orthogonal specific transfer resource (unappropriated orthogonal low delay utilization ratio of transmission resources is 0%) be not assigned with is checked whether, if had, then preferential the orthogonal specific transfer resource be not assigned with is distributed to new target UE.
If 2 all orthogonal specific transfer resources have all been assigned at least one target UE, then the capacity occupancy of network equipment to specific transfer resource has sorted.
The mode that network equipment calculates the capacity occupancy of specific transfer resource calculates according to " burst service mean interval information ", " the burst service mean interval information " of such as subscriber equipment 1 is 1 second, and the minimum time interval of system is 1 millisecond, then the capacity occupancy of current goal subscriber equipment to the specific transfer resource distributed is 0.1%, the capacity occupancy distributing to all target UEs of the capacity occupancy of this specific transfer resource is added, just obtains the capacity occupancy of this specific transfer resource.
3., after network equipment judges whether there is the described target UE of receiving in the capacity occupancy of each specific transfer resource, capacity occupancy is not more than the specific transfer resource of specified threshold.
In force, after network equipment determines that orthogonal specific transfer resource is distributed to target UE, by in the contextual information of the particular channel of the information record of target UE, calculate and preserve the load information (the capacity occupancy of namely orthogonal low delay transfer resource) of each orthogonal low delay transfer resource, to carry out uplink receiving use, and follow-up when being the access of new target UE Resources allocation use (considering that whether resource is by existing subscriber's hold facility), specifically see table 1.
Table 1
In force, described network equipment meet reshuffle condition after, all specific transfer resources are reshuffled.
The condition of reshuffling has a lot, enumerates several below.
Condition one, determine, under the part or all of target UE in current system reconfigures transfer resource or transmission plan situation, to reshuffle all specific transfer resources when network equipment, specifically can see Figure 15.
Such as, can ensure that each specific transfer resource is no more than specified threshold by code reassignment, the occupancy of No. 1 and No. 2 resource is such as had now to be all 0.5%, existingly carry out again the subscriber equipment 3 that a resources occupation rate is 1%, suppose if the special thresholding of each private resource is 1%, if unregulated words subscriber equipment 3 just can not be received, because the words that subscriber equipment 3 is multiplexed to No. 1 or No. 2 resource all can exceed thresholding, if but the business on existing No. 1 and No. 2 is all multiplexed in No. 1 resource, No. 1 just becomes 1%, such No. 2 resources just can have been received subscriber equipment 3, rear No. 2 resource occupation are received to become 1%.Therefore need to reshuffle in this process and just can complete.
If the target UE quantity that condition two activates low deferred traffic along with current area constantly reduces, such as target UE moves out current area and covers or the low deferred traffic of target UE deexcitation, can reshuffle all specific transfer resources, specifically can see Figure 16.
Such as, current have specific transfer resource not distribute to target UE, and the specific transfer resource distributed to have multiple subscriber equipment to carry out multiplexing.
Preferably, in order to control the impact that low delay transport layer is transmitted normal transmission layer service, the mode that network equipment can be controlled by call access control and load controls the ratio (such as sparse resource accounts for 1% of whole transfer resource ratio) that the sparse bag transmission of low delay transport layer takies whole low delay transfer resource.For the transmitting of low delay transport layer preferentially can be ensured under ensureing to transmit the situation that collides between low delay transport layer and general service transport layer, preferably method is for low delay transport layer distributes a higher power grade, and namely described network equipment is that low deferred traffic transport layer distributes the received power (specifically see Fig. 6) being greater than general service transport layer.
In Fig. 6, under ensureing that the transmission of low deferred traffic and general service transmit the situation that collides, network equipment can successfully solve low deferred traffic, then network equipment is that the transmission of low deferred traffic distributes different received power grades with general service transmission, realize in low deferred traffic transmission time base station to the object of the received power of low deferred traffic higher than the certain thresholding of general service, thus ensure the preferential receipt to low deferred traffic.Network equipment can by low time delay transfer resource preparation parameter mode, and the received power grade expected by network equipment when low delay activates low time delay transmission preparation, or occurs to notify in low time delay transmission preparation renewal process.
Except aforesaid way, also can eliminate based on non-orthogonal enhancing interference and strengthen transceiver technology by using, ensure that network equipment still can simultaneously correctly correctly receive the data of low delay transport layer and the data of general service transport layer when low delay transport layer and the transmission of general service transport layer business collide.
