Specific embodiment
The method and communication equipment of a kind of scheduling of resource distribution are the embodiment of the invention provides, for determining feedback acknowledgment Information emergency the second target device higher, the first equipment be the second target device distribute radio bearer resources, for First equipment feedback acknowledgment information, improves the resource utilization of system.
In order that those skilled in the art more fully understand the present invention program, below in conjunction with the embodiment of the present invention Accompanying drawing, is clearly and completely described to the technical scheme in the embodiment of the present invention, it is clear that described embodiment is only The embodiment of a part of the invention, rather than whole embodiments.Based on the embodiment in the present invention, should all belong to the present invention The scope of protection.
Technical solution of the present invention is mainly used in the scheduling method for wireless resource and equipment of access system of eating dishes without rice or wine, for example UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System).The present invention is proposed The up-downgoing resource allocation system frame diagram based on TCP state information it is as shown in Figure 1.Mainly include core network server, base Stand and terminal (user equipment, UE), the system framework also includes：Transport layer, PDCP (Packet Data Convergence Protocol, packet data convergence protocol)/RLC (Radio Link Control, wireless spread-spectrum technology) layer, MAC (Medium Access Control, medium education) layer and physical layer, it should be appreciated that as shown in Figure 1, also including application layer etc. other Layer, it is simply not shown.
Wherein, each layer functions of modules is as follows：
Application layer：Simulated environment parameter configuration module major function is that the parameter to be used in simulation process sets Put；The function of reading segment modules is mainly the information read included in each segment.
Transport layer：TCP initiator blocks determine the transmission rate of packet according to the situation for returning to ACK；Information extraction Module major function is：(1) extract TCP in TCP layer and send client information；(2) client information is sent according to TCP and estimates ACK feedback feelings Condition；(3) above- mentioned information is passed into MAC layer to be used for up-downgoing scheduling of resource allocation algorithm.
MAC layer：Up-downgoing resource is allocated and packet scheduling.
Below in the prior art, the dispatching algorithm of common several resource allocations does a brief summary, following institute Show：
(1) proportional fair scheduling (PF)
Proportional fair scheduling (Proportional Fair) can be that each user in cell distributes one preferentially Level.In each scheduling instance, priority user high can preferentially be scheduled.On the one hand PF dispatching algorithms make full use of subscriber channel Time-varying characteristics, on the other hand ensure that the balance between system multi-user diversity and fairness, therefore as radio communication system That is commonly used in system dynamic reads resource scheduling algorithm.
Its mathematic(al) representation is as shown in Equation 1：
Wherein, riRepresent user's current peak transfer rates of i, RiRepresent the Mean Speed that up to the present user i counts, j Represent the numbering of the user that selection is scheduled.
(2) polling dispatching algorithm (RR)
Polling dispatching algorithm (Round Robin), is also fair time dispatching algorithm.The algorithm core assumes that institute is useful Family has identical priority, it is ensured that all users distribute the resource of equal number in equal chance as system.For example, During one comprising the K system of user, can guarantee that the Probability p (k) that each user is scheduled is 1/K using RR algorithms.From Take for the angle of resource, RR dispatching algorithms are most fair, so, generally using the result of RR dispatching algorithms as the time The upper bound of fairness.
(3) max carrier to interference scheduling algorithm (Max C/I)
Max carrier to interference algorithm is also called Max C/I (Maximum Carrier to Interference) dispatching algorithm. The guiding theory of the algorithm is：By all users to be serviced, its carrier/interface ratio prediction to induction signal is received according to base station end Value carries out sequence from high to low, and is scheduled in this order.
Carrier/interface ratio：C/I=carrier signal strengths/interference signal intensity
Carrier/interface ratio typically reflects signal during spatial, and receiving terminal receives the quality of signal.Due to when any Carve, total energy ensures that the best user of carrier/interface ratio enjoys service power, and Max C/I algorithms can be described as one kind and typically utilize multi-user Diversity, makes the maximized dispatching algorithm of power system capacity.But, those users bad to channel condition, such as distance service base station Farther out, or in cell edge, or the user in deep fading, then it is very possible because cannot get send opportunity all the time and one Directly it is waited for.
Due to not accounting for any fairness, the main application of Max C/I algorithms is to hold as system under study for action The limiting value of amount, so that other dispatching algorithms are compared.
(4) improved weight limit time delay priority algorithm (M-LWDF)
Based on by the effective using being considered of the delay character of packet data package and channel condition, to reach most preferably The thought of scheduling, adjusts in improved weight limit time delay preferential (Modified Largest Weighted Delay First) In degree algorithm, the calculating of User Priority will not only be dependent on the quality condition of present channel, it is necessary to including data to be transmitted The associated time delays factor of queue.
In M-LWDF algorithms, user i t priority computing formula as shown in Equation 2：
Wherein, Q represents the qos parameter of user；RiT () is maximum transmitted speed λs of the user i in tiIt is the average of user i Throughput；DiT () is queue time delay Ts of the user i in t packetiIt is maximum delay that user i can tolerate.Can from above formula To find out, M-LWDF algorithms are that effective compromise has been done between channel throughput and buffer queue time delay, equivalent to PF algorithms The linear weighted function based on time delay factor is done.
Existing LTE descending resource allocation methods only considered the fairness between radio channel state or user, not Consider TCP uplink ACK feedbacks, the dispatching algorithm of several resource allocations sketched as described above.This can cause underlying resource point With can not be good fit with TCP, systematic function be limited.For example, when Cell Edge User uplink ACK feedback is by limited time, LTE is descending Resource distribution module still may be that the user distributes more Radio Resource.And the increase of user's downstream rate can not only add The limited problem of acute uplink ACK transmission, and other uplink ACKs can be influenceed to feed back the resource allocation of smooth user, cause be The reduction of system goodput.
In system framework as shown in Figure 1 above proposed by the present invention, the signaling that can be added between transport layer and MAC layer connects Mouth, i.e. TCP message extraction module, to will be seen that transmission layer state in resource allocation, mainly obtain user equipment anti- Present the rate information of ACK.If in addition, realizability of this framework in live network can be improved using TCP agent.Ying Li Solution, the status information that transport layer is obtained here can also be by other functional modules to realize.
On the basis of this framework, the present invention proposes the resource allocation algorithm that tcp state is perceived from two angles of up-downgoing To improve systematic function, specially：
A. descending resource allocation method only considered the fairness between radio channel state or user, not consider The feedback of TCP uplink ACKs.But when Cell Edge User uplink ACK feedback is received in limited time, LTE downlink resource distribute modules Still may be that the user distributes more Radio Resource.And the increase of user's downstream rate can not only aggravate uplink ACK biography Defeated limited problem, and other uplink ACKs can be influenceed to feed back the resource allocation of smooth user, cause system goodput Reduction.For problem above, we have proposed a kind of descending resource allocation method based on TCP uplink ACK feedback informations.It is logical The feedback velocity of statistics uplink ACK is crossed, is that downlink resource distribution is provided with maximum service speed.In the limitation of maximum service speed Under the conditions of resource allocation is carried out to user, it is to avoid by excessive RB (radio bearer, Radio Bearer) resource allocation to up ACK limited users, so as to improve resource utilization ratio.
B. in order to avoid network congestion, the transmission rate of TCP is determined according to the situation of feeding back ACK.Therefore, if Can not effectively distribute resource transmission more urgent ACK, will result in the low situation of network resource utilization.Asked to solve this Topic, we have proposed a kind of ascending resource distribution for perceiving tcp state and packet scheduling strategy.In eNodeB sides, the strategy passes through The tcp state of acquisition estimates wait situations of the different user ACK in upstream queue and according to time delay thresholding to ack msg Bag carries out emergency differentiation.The state of the emergency, channel quality and TCP transmitting terminals of comprehensive ACK, carries out ascending resource distribution.
Technical solution of the present invention is further described by way of example below, as shown in Fig. 2 for the present invention is real One embodiment schematic diagram of the method for scheduling of resource distribution in example is applied, including：
In embodiments of the present invention, after each user equipment receives the first tcp data bag, determine that each user equipment feeds back The remaining waiting time of confirmation ACK, confirmation ACK is corresponding with the first tcp data bag, can be real by step 201 and 202 It is existing, it is as follows：
201st, the first equipment obtains each second equipment and receives the delivery time of the first packet that the first equipment sends, surpasses Shi Chongchuan durations and current time；
In embodiments of the present invention, the first equipment obtains each second equipment and receives the first packet that the first equipment sends Delivery time, Retransmission timeout duration and current time；Can be that base station obtains the TCP numbers that each user equipment is received According to the delivery time of bag, Retransmission timeout duration and current time.It should be understood that the first equipment here can be base station, or User equipment, when the first equipment is base station, the second equipment is user equipment, and when the first equipment is user equipment, second sets Standby is base station, following, is base station with the first equipment, and the second equipment is to illustrate as a example by user equipment.
Exemplary, it is assumed that k-th N of user equipment transmissionkIndividual TCP bags are not received by ACK confirmations.Per number T is designated as according to the transmission time of bagk,n,1≤k≤K,1≤n≤Nk.The Retransmission timeout time of each user equipment is designated as RTOk。
202nd, the first equipment is calculated every according to transmission time of the first packet, Retransmission timeout time and current time Remaining waiting time from individual second equipment to the first equipment feedback acknowledgment information ACK；
In embodiments of the present invention, the first equipment obtains each second equipment and receives the first packet that the first equipment sends Delivery time, Retransmission timeout duration and after current time, transmission time, time-out weight of first equipment according to the first packet Biography time and current time, calculate remaining waiting time of each second equipment to the first equipment feedback acknowledgment information ACK.I.e. Base station calculates each user equipment and treats instead according to transmission time of the first tcp data bag, Retransmission timeout time and current time The remaining waiting time of feedback confirmation ACK.
It is exemplary, when starting in a uplink scheduling cycle, base station calculate can tolerate either with or without the TCP bags being identified Residual waiting time dk,n, as shown in Equation 3.
dk,n=RTOk+Tk,n-system_time,1≤k≤K,1≤n≤Nk(formula 3)
Wherein, system_time is current system time, RTOkRepresent the Retransmission timeout time of user equipment k.
Further, the patient residual waiting time thresholding of TCP bags can also be calculated for d_thk, as shown in Equation 4：
d_thk=η × RTOk(formula 4)
Wherein, η is internal constant between (0,1).
203rd, remaining waiting time and/or transfer control protocol TCP shape of first equipment according to feedback acknowledgment information ACK State, is the second target device distribution radio bearer resources, to cause that the second target device is set using radio bearer resources to first Standby feedback acknowledgment information ACK, the second target device is that remaining waiting time is minimum and/or transport layer controls layer protocol tcp state The second equipment in preset condition.
