Description
Technical field
The present invention relates to network communications technology field, particularly a kind of methods, devices and systems of channel unit scheduling.
Background technology
HSDPA (High Speed DownlinkPackages Access, high speed downlink packet access technology) be to realize improving WCDMA (Wideband Code Division Multiple Access, the Wideband Code Division Multiple Access (WCDMA) access) the of paramount importance technology of network high-speed downlink message transmission rate, be 3GPP (3rd GenerationPartner Project, third generation partner program) the asymmetric demand of up-downgoing data service puts forward in order to satisfy in the R5 agreement, it can be on the basis that does not change existing WCDMA system network architecture, improve user's downstream data traffic speed greatly, theoretical maximum can reach 14.4Mbps.
After introducing HSDPA, the shortage of the uplink capacity that causes for the growth that reduces because of the down link load, further improve the up average throughput and the capacity of single user and system, and shortening postpones, thereby carry out multimedia service and bag transfer of data better, introduced HSUPA (HighSpeed Uplink Packet Data Access, high speed uplink bag data insert) technology again.This is that 3GPP is organized in a kind of new technology that improves up transfer rate of introducing in the R6 agreement, it adopts up fast dispatch, HARQ (the Hybrid Automatic Repeat Request of Node B, the automatic re-transmission of mixing), soft handover, 2msTTI (Transmission Time Interval, Transmission Time Interval) lack the frame transmission technology, the peak-peak speed that can support in theory is 5.76Mbps.
As shown in Figure 1, be the protocol architecture of existing HSUPA.After in the WCDMA system, having introduced HSUPA, at UE (User Equipment, subscriber equipment) side, increased MAC (MediumAccess Control, the medium access control) layer entity MAC-es, MAC-e entity, be used for realizing retransmitting and function such as MAC-d PDU (Protocol Data Unit, protocol Data Unit) is multiplexing such as HARQ.In order to support the fast dispatch of Node B, the MAC-e entity of UTRAN (Universal MobileTelecommunications System Territorial Radio Access Network, universal terrestrial access network) side has moved down into Node B; In order to support the grand diversity of HSUPA, MAC-es is positioned at SRNC (Server Radio Network Controller, service wireless network controller).Increase E-DCH (Enhanced-Dedicated Channel, the dedicated channel of enhancing) transmission channel between MAC layer and the physical layer and carried transmission data block.
HSUPA has increased several physical channels in physical layer, uplink physical channel has increased E-DPCCH (E-DCH Dedicated Physical Control Channel, the Dedicated Physical Control Channel that strengthens) and E-DPDCH (E-DCH Dedicated Physical Data Channel, the Dedicated Physical Data Channel that strengthens), down physical channel has increased E-AGCH (E-DCH Absolute Grant Channel, the E-DCH absolute grant channel), E-RGCH (E-DCH Relative Grant Channel, E-DCH relative authorization channel), E-HICH (E-DCH HARQ Acknowledgement Indicator Channel, E-DCHHARQ confirms indicating channel).Up E-DPDCH is used to carry the transmission data of HSUPA user uplink; Up E-DPCCH carries the signaling of following of demodulating data channel E-DPDCH.Descending E-AGCH is a common signal channel, is served the maximum available transmission rate of sub-district indication UE or the power at E-DCH wireless connections place by the user; Descending E-RGCH is a dedicated channel, the fastest can be by the uplink speed of 2ms time rapid adjustment UE; Descending E-HICH is a dedicated channel, ACK/NACK (Acknowledgement/Negative Acknowledgement confirms/deny) information whether feedback user receiving process data are correct.CE (Channel Element, Channel Elements) refers to Channel Elements, a CE equals an AMR (Adaptive Multi-rate, adaptive multi-rate) voice of 12.2k, comprise the resource that 3.4k DCCH (DedicatedControl Channel, Dedicated Control Channel) consumes on base band.When cell initial was set up, Node B can tell up available credit of RNC (Radio Network Controller, radio network controller) and the consumption rule of credit by " Audit response " message, as shown in Figure 2.Wherein Xiang Guan information as shown in Table 1 and Table 2,

The CE resource sum that Node B can use by the present Node B of the cell in the table 1 " UL Capacity Credit " notice RNC.Table 2 has provided the CE consumption rule of Node B to different SF, and Node B notify RNC by cell, and CE resource sum in the RNC associative list 1 and the consumption rule in the table 2 just can be carried out access to UE.For R99 is professional, RNC distributes the CE resource according to cell " Min UL channelisation code length " and its corresponding CE consumption rule that NBAP (Node B Application Protocol, NodeB application protocol) message is carried.
After having introduced HSUPA, RNC can dispose each user " Maximum Set ofE-DPDCHs " when foundation/reconfiguring radio link, as shown in table 3, its meaning is equal to " the Min ULchannelisation code length " among the R99, the distribution method of CE is consistent with the CE distribution method of R99 business, and the CE that carries out the user according to " Maximum Set ofE-DPDCHs " distributes and access.

| Maximum Set of E-DPDCHs | ENUMERATED (vN256，vN128，vN64， vN32，vN16，vN8， vN4，v2xN4，v2xN2， v2xN2plus2xN4，...) |
In actual commercial net, can be between operator and the equipment supplier according to License, promptly the number of CE is paid.After HSUPA is introduced into, compare the R99 business, owing to adopted the HARQ technology among the HSUPA, adopted quick re-transmission in physical layer, reduced the propagation delay time of packet, and retransmission data packet may can merge, improved demodulation performance, increased network capacity, this is the advantage of HARQ, but the re-transmission of HARQ causes in order to obtain identical MAC layer speed, and HSUPA need consume more CE than R99, promptly will reach identical MAC layer speed, the CE that HSUPA consumes increases along with increasing of number of retransmissions.Simultaneously, soft hand-off also is used among the HSUPA, and soft hand-off does not interrupt transfer of data continuously, has macro diversity, can improve up capacity.But at soft handover area, link is set up in UE and a plurality of sub-district, takies several times CE resource, and is therefore bigger to the consumption of CE resource.More than 2 be to cause HSUPA to consume the big main cause of CE resource.
When having adopted uplink enhanced link to carry out transfer of data, up speed has obtained improving significantly when up, correspondingly, the consumption of CE resource is also increased significantly, and in this case, up CE resource can become the bottleneck that influences number of users and throughput.In the prior art, the distribution method of CE is the fixed allocation method, no matter promptly how many actual speed rate of user is, all fixedly takies " Maximum Set ofE-DPDCHs " corresponding CE number.Its shortcoming mainly contain following some:
RNC basis " Maximum Set ofE-DPDCHs " was carried out the access of UE when 1, the user inserted, and under the certain situation of the configured number of CE, the number of users of access is fewer like this.
2, because HSUPA user's speed is fast-changing according to the mandate indication of Node B, when actual speed rate during well below speed that " Maximum Set ofE-DPDCHs " supports, method according to the CE fixed allocation can reduce the CE service efficiency greatly, under certain CE configuration, the final throughput of system also can lowly be affected owing to the service efficiency of CE.
Therefore, the shortcoming of prior art is: according to " Maximum Set ofE-DPDCHs " user is carried out access and make that the number of users of access is few, in addition, make the efficient of the CE utilization of resources low according to the method for CE fixed allocation, thereby make that the throughput of system is lower.

Embodiment
The embodiment of the invention provides a kind of method of channel unit scheduling, and by the embodiment of the invention, the base station is adjusted the CE that distributes to the user according to user's speed, has improved the service efficiency of CE.In addition, RNC is according to default admittable regulation, for example: GBR (Guaranteed Bit Rate, guarantee bit rate) information or GBR, MBR (Maximum Bitrate, maximum bit rate) and MinSF (MinimumSpreading Factor, minimal frequency spreading factor) minimum value in is carried out user's access, has increased the number of users of access significantly.
As shown in Figure 3, for the embodiment of the invention to the flow chart that the user carries out the method for access, can may further comprise the steps:
S301 obtains the current available CE sum in base station.
When cell initial was set up, RNC received the current available CE sum in this base station that the base station issues by cell " UL Capacity Credit ".
S302, according to default admittable regulation and current base station can with the CE sum user is carried out access.
Should default admittable regulation can comprise the user is carried out access according to the minimum value among GBR information or GBR, MBR and the MinSF.For HSUPA, NBAP message can dispose GBR according to user's traffic performance, and is as shown in table 4.
Table 4MAC-es Guaranteed Bit Rate
| The IE group name | Presence bit | Scope | IE type and index | Semantic description |
| MAC-es Guaranteed Bit Rate | INTEGER(0..2^24-1，...) | Unit: bit/s |
Because GBR is the key factor that the base station is considered when scheduling, therefore GBR can be guaranteed as far as possible, more can embody professional QoS (Quality of Service than Maximum Set ofE-DPDCHs, service quality) requirement, and GBR is also much smaller than the maximum rate that Maximum Set ofE-DPDCHs is supported generally speaking, therefore when the user inserts, RNC carries out the qos requirement that user's access not only can embody the user according to GBR, compare when carrying out user's access, carry out user's access according to GBR and can also increase the access number of users significantly according to Maximum Set ofE-DPDCHs.
Ordinary circumstance, because GBR is much smaller than MBR, so the CE number of MBR correspondence is greater than the CE number of GBR correspondence, and MinSF is basic corresponding with MBR, therefore the CE number of MinSF correspondence also is greater than the CE number of GBR correspondence, can increase the access number of users significantly so carry out user's access according to GBR.For example: if the CE sum that the base station issues is 32, user's Maximum Set of E-DPDCHs is configured to 2SF4, GBR is configured to 64kbps, if the CE number that 2SF4 consumes is 16 CE, the SF of 64kbps correspondence is SF16, and the CE number of its consumption is 2, so according to prior art, RNC can only 2 such HSUPA users of access, and the scheme that adopts the embodiment of the invention to provide, RNC can 16 users of access.
Preferably,, also can carry out access to the user according to the minimum value among GBR, MBR and the MinSF in order further to increase the number of users of access, as the formula (1),
CE
Init＝min{CE(GBR)，CE(MBR)，CE(MinSF)}(1)
Wherein CE (GBR) is the CE of GBR correspondence; CE (MBR) is the CE of MBR correspondence; CE (MinSF) is meant the CE of MinSF correspondence.
Above-mentioned the user is carried out the method for access, RNC carries out access according to default admittable regulation and current available CE sum to the user, has increased the number of users of access significantly.
As shown in Figure 4, the flow chart for the dispatching method of embodiment of the invention Channel Elements can may further comprise the steps:
S401 obtains the current available Channel Elements CE sum in base station.
When cell initial was set up, RNC received the current available CE sum in this base station that the base station issues by cell " UL Capacity Credit ".
S402, according to default admittable regulation and current base station can with the CE sum user is carried out access.
Should default admittable regulation can comprise the user is carried out access according to the minimum value among GBR information or GBR, MBR and the MinSF.For HSUPA, NBAP message can dispose GBR according to user's traffic performance, and is as shown in table 4.Because GBR is the key factor that the base station is considered when scheduling, therefore GBR can be guaranteed as far as possible, more can embody professional qos requirement than Maximum Set of E-DPDCHs, and GBR is also much smaller than the maximum rate that Maximum Set ofE-DPDCHs is supported generally speaking, therefore when the user inserts, RNC carries out the qos requirement that user's access not only can embody the user according to GBR, compare when carrying out user's access, carry out user's access according to GBR and can also increase the access number of users significantly according to Maximum Set ofE-DPDCHs.
Ordinary circumstance, because GBR is much smaller than MBR, so the CE number of MBR correspondence is greater than the CE number of GBR correspondence, and MinSF is basic corresponding with MBR, therefore the CE number of MinSF correspondence also is greater than the CE number of GBR correspondence, can increase the access number of users significantly so carry out user's access according to GBR.For example: if the CE sum that the base station issues is 32, user's Maximum Set of E-DPDCHs is configured to 2SF4, GBR is configured to 64kbps, if the CE number that 2SF4 consumes is 16 CE, the SF of 64kbps correspondence is SF16, and the CE number of its consumption is 2, so according to prior art, RNC can only 2 such HSUPA users of access, and the scheme that adopts the embodiment of the invention to provide, RNC can 16 users of access.
Preferably, in order further to increase the number of users of access, can carry out access to the user according to the minimum value among GBR, MBR and the MinSF, as the formula (1).
S403 to the user of access, adjusts the CE that distributes to the user according to user's speed.After the user was by the RNC access, the base station was adjusted the CE that distributes to the user according to user's speed.This user's speed can be Mean Speed or instant speed.For example, the base station is adjusted the Mean Speed of promptly adding up user in a period of time according to user's Mean Speed to the CE that distributes to the user, and judges the relation of needed CE of this Mean Speed and the current user's of distributing to CE.Above-mentioned a period of time can be preestablished by the base station, also can rule of thumb be worth artificial setting, and the length of how setting is during this period of time determined according to the implementation of reality.If the needed CE of Mean Speed is far smaller than the current user's of distributing to CE, just explanation is owing to the reason of interface-free resources or IUB resource or the data source of user own, user's reality has not needed so many CE, in order to improve the utilization ratio of CE, at this moment just can reduce the CE that distributes to the user, certainly can not reduce the CE that distributes to this user unlimitedly, CE after guaranteeing to reduce can satisfy the demand of customer service, and at this moment just saved CE from the CE that distributes to this user can be distributed to other has the user who needs.In addition, the base station also can be adjusted the CE that distributes to the user according to user's instant speed.Such as in the speed that detects the user sometime, the speed of distributing to the user is adjusted according to the speed in this moment.
Further, for the HSUPA user of a base station, it can be divided into two classes according to the attribute of its Radio Link, a class is the user of service RLS, and another kind of is the user of non-service RL.User for service RLS, if Mean Speed or the instant needed CE of speed are equal to or greater than the current user's of distributing to CE, then CE may become the principal element of limited subscriber speed, at this moment just need to increase the CE that distributes to this user, in order to guarantee the utilance of CE, as long as the CE after increasing can satisfy the needs of service RLS customer service, not needing increases CE too much for service RLS.The CE number of distributing to the user is adjusted in time according to user's speed in the base station, has improved the service efficiency of CE.For example: Fig. 5 has provided the throughput of a ftp business and the CE distribution condition under the embodiment of the invention and the prior art, and service interval is initiated.Fig. 5 (a) is user's a actual throughput rates, solid line among Fig. 5 (b) is represented the CE number that distributes for the user by existing scheme by fixed allocation, as can be seen in a period of time, no matter how user's throughput changes, all distribute to 16 CE of user regularly, dotted line among Fig. 5 (b) represents to distribute to according to the scheme that the embodiment of the invention provides user's CE number, distributing to user CE number as can be seen by Fig. 5 (b) changes along with the variation of user's throughput, when user's throughput is higher, distribute to 16 CE of user, when user's throughput hangs down, distribute to about 2～3 CE of this user, the base station just has more residue CE resource allocation to give other users like this.
And according to 3GPP agreement 25.309, for the user of service RLS, the base station can send scheduling authorization increases user's speed, and for the non-user who serves RL, the base station is merely able to allow user's speed reduce.User for non-service RL, the base station is how dispatch it the service RLS sub-district of not knowing the user, therefore how much speed of also not knowing next moment user definitely is, no matter distribute how many CE therefore for non-service RL user, all might be able to not satisfy next CE demand of user's reality constantly.Therefore when the user of service RLS need increase, can seize the CE that distributes to non-service RL user, the CE that increases for service RLS user can be fully utilized to improve the throughput of system like this.For example: according to the scheme of the embodiment of the invention, two kinds of situations of difference emulation: a kind of is the CE that does not seize non-service RL user; Another is the CE that seizes non-service RL user; Under following scenario, carry out emulation: the Wrap-Around scene, 135UEs, Full Buffer, 128CE/NodeB, simulation result is as shown in table 5.
The system throughput that obtains under table 5 Different Strategies
| System throughput (Mbps) | |
| The system throughput that prior art obtains (not seizing non-service RL user's CE) | 7.82 |
| The system throughput that the embodiment of the invention obtains (seizing non-service RL user's CE) | 18 |
Behind the CE that seizes non-service RL user, the throughput of system is increased to 18M from 7.82M, improves highly significant as can be seen from Table 5.
The method of above-mentioned channel unit scheduling, RNC carries out user's access according to the default current available CE sum of admittable regulation and base station, increased the number of users of access significantly, the CE that distributes to the user is adjusted in time according to user's speed in the base station, has improved the service efficiency of CE.And the CE to service RLS user and non-service RL user has carried out differentiated treatment, when belonging to that the CE that serves RLS user need increase and current when not having unnecessary CE, the CE that belongs to non-service RL user can be seized, thereby make CE be distributed to service RLS user fully, improved the throughput of system widely.
