具体实施方式 Detailed ways

[0018] 由于在LTE系统中当用户终端接入网络后,其并不持续占用为其分配的物理信道资源,因此为了保证接入网络的用户终端占用的物理信道资源的合理分配,减小物理资源的利用率,本发明实施例提供了一种LTE网络规划仿真方法,该方法中根据接入的用户终端当前进行的业务的优先级,将用户终端划分到不同的优先级业务队列中,针对每个优先级队列中的用户终端,确定该用户终端的优先级,按照优先级在该业务队列中为用户终端分配相应的物理信道资源。 [0018] Since when the user terminal accesses the network, it does not continuously occupy the physical channel resources assigned in the LTE system, so in order to ensure a reasonable allocation of physical channel resources occupied by the user terminal to access network, to reduce the physical utilization of resources, the present invention provides a LTE network planning simulation method according to the access priority user terminals for current traffic, the user terminal will be divided into different priority service queue for each user terminal in the priority queue, determining the priority of the user terminal, assign the corresponding physical channel resources to the user terminals in the service according to the priority queue. 由于在本发明实施例中当用户终端接入后,按照用户终端的优先级进行物理信道资源的分配,因此可以保证需要物理信道资源的用户终端可以分配到相应的资源,从而降低了物理信道资源的浪费,提高了物理信道资源的利用率。 Since the embodiment when a user of the present invention after the terminal accesses, assigned physical channel resources according to the priority of the user terminal, thereby ensuring that require physical channel resource user terminal may be assigned to the appropriate resources, thereby reducing the physical channel resources waste, improve the utilization of physical channel resources.

[0019] 下面结合说明书附图,对本发明实施例进行详细说明。 [0019] the following description in conjunction with the accompanying drawings, embodiments of the present invention will be described in detail.

[0020] 图1为本发明实施例提供的LTE网络规划仿真过程,该过程包括以下步骤: [0020] FIG 1 LTE network planning simulation process according to an embodiment of the present invention, the process comprising the steps of:

[0021] SlOl :根据接入的每个用户终端当前进行的业务的优先级,将用户终端划分到对应的优先级业务队列中。 [0021] SlOl: According to the priority of each user's access terminal is currently performed service, the user terminal will be divided into a corresponding priority queue service.

[0022] 在本发明实施例中将每种业务划分了优先级,因此当用户终端接入后,根据每个用户终端当前进行的业务的优先级,可以将每个用户终端划分到对应的优先级业务队列中。 [0022] prioritizes operations in each of the embodiments in the embodiment of the present invention, so when a user terminal accesses, according to the priority of each user terminal is currently performed service, for each user terminal may be divided into a corresponding priority business class queue.

[0023] S102:针对每个优先级业务队列中的每个用户终端,根据该用户终端的保证比特率(Guaranteed Bit Rate,GBR)业务是否得到保证、信干比(SINR)对应的每个资源块(RB) 的比特数、以及上个设定时间长度中该用户终端的的吞吐率,确定该优先级队列中该用户终端的优先级。 Each terminal of each user for each resource priority service queue, in accordance with guaranteed bit rate of the user terminal (Guaranteed Bit Rate, GBR) traffic guaranteed whether the signal to interference ratio (SINR) corresponding to: [0023] S102 bits block (RB), and a set length of time the throughput of the user terminal determines the priority of the priority queue for the user terminal.

[0024] 确定该优先级队列中该用户终端的优先级具体包括:确定信干比对应的每个资源块的比特数与上个设定时间长度中该用户终端的吞吐率的商;根据该商,及该用户终端的保证比特率业务是否得到保证,确定该优先级队列中该用户终端的优先级。 [0024] The priority queue to determine the priority of the user equipment specifically includes: determining the number of bits corresponding to the SINR of each resource block is set the length of time the user terminal throughput provides last; According to this whether the provider, and the guaranteed bit rate service guaranteed user terminal, determines the priority of the priority queue for the user terminal.

[0025] S103 :根据确定的每个用户终端的优先级,为用户终端分配物理信道资源。 [0025] S103: The priority determination for each user terminal, a user terminal is assigned to physical channel resources.

[0026] 在本发明实施例中在当用户终端接入网络后,由于其并不持续占用专用的物理信道资源,因此当用户终端接入后,采用该动态方法重新为接入的用户终端分配物理信道资源,可以使物理信道资源的利用率提高,并且也有利提高其他用户终端的业务体验。 [0026] In the embodiment of the present invention when the user terminal accesses the network, since it is not continuously occupy dedicated physical channel resource, so when a user terminal accesses, using the method of dynamic re-allocation of user terminals in the access physical channel resources, utilization can be made to improve the physical channel resources, and is also advantageous to improve the service experience of other user terminals.

[0027] 当用户终端接入后对用户终端重新分配物理信道资源时,首先根据根据该接入的每个用户终端当前进行的业务的优先级,将用户终端划分到对应的优先级业务队列中。 When [0027] When the access terminal user terminal reallocated physical channel resources to users, according to the first priority to each user according to the service of the access terminal is currently performed, the user terminal will be divided into a corresponding priority queue service . 即在本发明实施例中针对每种业务对物理信道资源的需求,将业务进行了优先级的划分。 I.e., for each service in the embodiment need for physical channel resources will be prioritized traffic is divided in the present invention.

[0028] 由于在本发明实施例中将每种业务划分了优先级,因此根据接入的每个用户终端进行的业务,可以将用户终端划分到对应的优先级队列中,例如用户终端A当前进行的业务的优先级为2级,用户终端B当前进行的业务的优先级为1级,用户终端C当前进行的业务的优先级为2级,用户终端D当前进行的业务的优先级为3级,则根据每个用户终端当前进行的业务的优先级,将用用户终端B划分到第一优先级的业务队列中,将用户终端A和用户终端C划分到第二优先级的业务队列中,将用户终端D划分到第三优先级的业务队列中。 [0028] Since in the embodiment of the present invention in each embodiment, prioritized traffic, according to the service and therefore access to each user terminal, the user terminal may be classified into a corresponding priority queue, for example, the user terminal A is currently priority service made for stage 2, priority service user terminal B is currently carried out for the level 1, the priority of service of the user terminal C is currently performed for the stage 2, priority service user terminal D currently performed 3 level, the priority of each user terminal in accordance with the ongoing traffic, the user terminal B by dividing the first queue priority traffic, the user terminal a and the user terminal C is divided into a second priority service queue the user terminal D is divided into third priority traffic queue.

[0029] 将每个接入的用户终端根据当前进行的业务的优先级,划分到对应的优先级业务队列中后,需要根据业务队列的优先级为用户终端分配物理信道资源。 After [0029] The access terminal of each user according to the priority of the ongoing operations, the division corresponding to the priority service queue assigned physical channel resources required for the user terminal according to the service priority queue. 具体的为,按照业务队列的优先级,首先为优先级较高的业务队列中的用户终端分配物理信道资源,之后再为优先级较低的业务队列中的用户终端分配物理信道资源。 Specifically, for the priority queue according to the service, the first terminal is assigned physical channel resources to higher priority queue service user, then assign the physical channel resources and then lower priority traffic queue user terminal.

[0030] 而具体的在对每种业务队列中的用户终端分配物理信道资源时,为了保证对物理信道资源要求较高的用户终端首先被分配物理信道资源,在本发明实施例中还可以确定每种优先级的业务队列进行物理信道资源分配的用户终端的顺序,当确定了用户终端的顺序后,按照确定的用户终端的顺序依次分配物理信道资源。 When [0030] the specific terminal assigned physical channel resources for each traffic queue users, in order to ensure the user a higher physical channel resources required by the terminal are first assigned physical channel resources, this embodiment may also be determined in the present invention order of the user terminal for each service priority queues assigned physical channel resources, when the user terminal determines the order assigned physical channel resources to determine the order that the user terminal.

[0031] 在每种优先级的业务队列中确定分配物理信道资源的用户终端的顺序时,可以确定该优先级的业务队列中每个用户终端的优先级。 When the physical channel resources assigned sequentially user terminals [0031] determined in each queue priority traffic, it may determine the priority of the priority queue for each service user terminal. 当在每个优先级业务队列中确定了每个用户终端的优先级后,根据该队列的业务被分配的物理信道资源,按照每个用户的优先级, 分配相应的物理信道资源。 When the determined priority of each user terminal traffic in each priority queue, traffic in accordance with the physical channel resources assigned queue according to the priority of each user is assigned a respective physical channel resources.

[0032] 由于在本发明实施例中将业务划分了优先级,而用于分配的物理信道资源的数量是有限的,因此可以根据每种业务的优先级,为每种业务分配相应数量的物理信道资源,例如当业务的优先级比较高时,可以为该业务分配较多的物理信道资源。 [0032] Since the embodiment of the present invention will, prioritized traffic, and the number of channel resources allocated for a physical channel is limited, it is possible according to the priority of each service, a corresponding number of physical distribution service for each channel resources, e.g., when the high priority service, that service can allocate more physical channel resources. 当某优先级的业务队列被分配的物理信道资源,已经被高优先级的用户终端占用完后,该物理信道资源的分配过程结束,此时认为该优先级业务队列中未被分配物理信道资源的用户终端在该时刻不需占用物理信道资源。 When the physical channel resources of a priority traffic queue assigned, has been a high priority user terminals occupied after the end of the dispensing process to the physical channel resources, in which case that this priority service queue is not allocated physical channel resources user terminal at that time without physical channel resources occupied.

[0033] 具体的在本发明实施例中在每个优先级业务队列中确定每个用户终端的优先级时,是根据该用户终端的保证比特率业务是否得到保证、信干比对应的每个资源块的比特数、以及上个设定时间长度中该用户终端的的吞吐率确定的,由于上述确定用户终端优先级的因素,可以反映用户终端对物理信道资源的需求情况。 [0033] Specifically in the embodiment is determined for each user terminal in each priority queue in priority traffic embodiment of the present invention, whether guaranteed service according to a guaranteed bit rate of the user terminal, each corresponding signal to interference ratio number of bits of resource blocks, and a set length of time the user terminal throughput determined, since the user terminal determines the priority factors can reflect the user terminal needs for physical channel resources. 因此当根据上述各个因素确定了用户终端的优先级后,优先级较高的用户终端其对物理信道资源的需求较强烈,需要首先满足优先级最高的用户终端的物理信道资源需求。 Therefore, when the priority is determined based on the respective user terminal factors, the higher priority user terminal needs its physical channel resources, relatively strong need to meet the resource requirements of the physical channel of the highest priority user terminal.

[0034] 在根据用户终端的保证比特率业务是否得到保证、信干比对应的每个资源块的比特数、以及上个设定时间长度中该用户终端的的吞吐率,确定每个用户终端的优先级时,可以根据下述公式进行计算, [0034] In the GBR traffic whether the user terminal is assured, the number of bits SIR corresponding to each resource block, and a set length of time the throughput of the user terminal, each user terminal is determined when the priority can be calculated according to the formula,

RBrate RBrate

[0035] Pue =-+ Ji1 [0035] Pue = - + Ji1

Hi StoryThroughput ΰ Hi StoryThroughput ΰ

[0036] 上述公式中Pue为确定的用户终端的优先级,RBrate为该SINR对应的每个资源快的比特数,Fqcb为QoS调度公平因子,当用户进行的业务为GBR业务,并且该GBR业务得到保证时,该Fws的值为0,当该GBR业务未得到保证时,该Fqcb的值为1,当该用户进行的业务非GBR业务时,该Fws的值为0,HistoryThroughput为该用户终端在上个设定时间长度的吞吐量,具体根据该用户在该设定时间长度内的流量信息确定。 [0036] The above formula is the priority Pue, RBrate user terminal determines the number of bits for each fast resource corresponding to the SINR, Fqcb QoS scheduling fairness factor is, when the traffic of GBR traffic for the user, and the GBR traffic when assured, Fws the value 0, when the GBR traffic is not guaranteed, the Fqcb value of 1, when the user performs non-GBR traffic service, the Fws value 0, HistoryThroughput for the user terminal in a certain length of time set on, the user is specifically determined according to the length of the traffic information within a set time. 该设定的时间长度可以为传输时间间隔(TTI),该HistoryThroughput的取值具体为,当该用户终端在上个设定时间长度被调度了,该用户终端在该设定时间长度中的的吞吐率,即为该被调度的用户终端在该时间长度中的实际吞吐量,当该用户终端在上个设定时间长度未被调度时,且该用户终端在上个设定时间按间隔吞吐率不为O时,该用户终端的在上个设定时间长度的吞吐率为(l-α ) XHistoryThroughput,α为0. 1与0. 5之间的数值,较佳的α可以取值为0. 1。 The length of time may be set as a transmission time interval (the TTI), the value of HistoryThroughput specifically, when the length of a user terminal in the set time is scheduled, the user terminal in the set length of time throughput, i.e. the actual scheduled user terminals in a certain length of time, when the user terminal is set at a length of time not scheduled, and the user terminal over a set time intervals throughput when the rate is not is O, in a set length of time the user terminal throughput is (l-α) XHistoryThroughput, α is a number between 0.1 and 0.5, preferably a value of [alpha] can be 0.1.

[0037] 由于在LTE系统中,当用户终端接入后并不持续占用物理信道资源,因此在本发明实施例提供的LTE网络规划仿真方法中,对接入的用户终端按照优先级重新分配物理信道资源,而非使接入的用户终端持续占用专用的物理信道资源,因此当用户终端接入后,采用该动态方法重新分配物理信道资源,可以使物理信道资源的利用率提高,并且也有利提高其他用户终端的业务体验。 [0037] Since in the LTE system, when a user terminal access is not continuously occupy the physical channel resources, the LTE network planning simulation method provided in the embodiment, the user of the access terminal re-allocated physical embodiment in accordance with the priority of the present invention, channel resources, rather than having the user access terminal continuously occupy dedicated physical channel resource, so re-allocated physical channel resources when the user terminal accesses, using the dynamic method, it allows the utilization of physical channel resources increases, and is also advantageous improve the service experience of other user terminals.

[0038] 另外,在本发明实施例中根据用户终端进行的业务的优先级,以及每个用户终端对物理信道资源的需求,依次调度每个用户终端,图2为本发明实施例提供的用户终端的调度过程,该过程包括: [0038] Further, in priority, and each user service performed according to embodiments of the present invention, a user terminal according to the terminal need for physical channel resources, each user terminal scheduled turn, the user 2 according to an embodiment of the present invention terminal scheduling process, the process comprising:

[0039] S201 :在仿真过程中进行预处理,即进行N次迭代处理,其中N为不小于1的整数。 [0039] S201: pre-processing in the simulation process, i.e., processing for N iterations, where N is an integer not less than 1.

[0040] 为了便于获取用户终端在上个设定时间长度中的数据信息,在采用本发明实施例提供的方法对用户终端进行调度之前,需要进行N次2迭代处理,以便获取相应的数据信肩、ο [0040] In order to facilitate access to information in the user terminal data on a set length of time, before the user terminal scheduling method according to an embodiment of the present invention, the need for N 2 times an iterative process, in order to obtain the corresponding data channel shoulder, ο

[0041] S202:根据待调度的每个用户终端当前进行的业务的优先级,将用户终端划分到对应的优先级业务队列中。 [0041] S202: The priority of each user terminal is currently scheduled to be performed by the service, the user terminal will be divided into a corresponding priority queue service.

[0042] S203 :按照业务队列的优先级,调度每个用户终端。 [0042] S203: service priority according to the scheduling queues for each user terminal.

[0043] 由于在本发明实施例中将每种业务划分了优先级,因此根据待调度的每个用户终端进行的业务,可以将用户终端划分到对应的优先级队列中,例如用户终端A当前进行的业务的优先级为1级,用户终端B当前进行的业务的优先级为1级,用户终端C当前进行的业务的优先级为3级,用户终端D当前进行的业务的优先级为2级,则根据每个用户终端当前进行的业务的优先级,将用户终端A和用户终端B划分到第一优先级的业务队列中,将用户终端D划分到第二优先级的业务队列中,将用户终端C划分到第三优先级的业务队列中。 [0043] Since in the embodiment of the present invention in each embodiment, prioritized traffic, so according to the service for each user terminal scheduled to be performed, the user terminal may be classified into a corresponding priority queue, for example, the user terminal A is currently priority service made for level 1, the priority of service of the user terminal B is currently carried out for the level 1, the priority of service of the user terminal C is currently performed for level 3, the priority of service of the user terminal D is currently carried out for the 2 level, the priority of each user terminal in accordance with the ongoing traffic, the user terminal a and the user terminal B is divided into a first queue priority traffic, the user terminal D is divided into a second priority service queue, the user terminal C is divided into the third priority traffic queue.

[0044] 当将用户终端划分到对应的优先级业务队列中后,根据每种业务队列的优先级, 对每个用户终端进行调度。 [0044] When the user terminal is divided into a corresponding priority queue service, according to each traffic priority queue, performs scheduling for each user terminal. 例如上述过程中将用户终端A和用户终端B划分到第一优先级的业务队列中,将用户终端D划分到第二优先级的业务队列中,将用户终端C划分到第三优先级的业务队列中。 For example in the above-described process the user terminal A and the user terminal B is divided into a first queue priority traffic, the user terminal D is divided into a second queue priority traffic, the user terminal C is divided into the third priority traffic queue. 由于业务队列的优先级分别为第一优先级的业务队列、第二优先级的业务队列和第三优先级的业务队列,因此按照业务队列的优先级,应该首先调度第一优先级业务队列中的用户终端,之后是第二优先级的业务队列中的用户终端,再其次才是第三优先级业务队列中的用户终端。 Since the service priority queues are a first priority service queue, the second priority service queue and the third priority service queue, so according to the service priority queue, a first priority should first scheduling service queue the user terminal after the user terminal of the second priority service queue, and then followed by the user terminal of the third priority service queue.
