Definitions
- This document relates to, but is not limited to, the field of communications, and in particular, to a user equipment scheduling method, apparatus, and system.
- the scheduling algorithm of the user equipment plays a key role in obtaining the resources that satisfy the service requirements and ensuring the overall system throughput in the cell.
- the main problem solved by the scheduling algorithm of the MAC layer is to decide which users to allocate to at what time.
- kind of wireless resources to communicate for example, the Long Term Evolution (LTE) standard system developed by the 3rd Generation Partnership Project (3GPP).
- the throughput generally refers to the amount of data transmitted per unit time.
- the fairness refers to whether all user equipments (User Equipments, UEs) of the cell have obtained certain service opportunities.
- the purpose of the MAC layer scheduling algorithm is to use the time-varying characteristics of the UE to obtain multi-user diversity gain, improve the overall throughput of the system, and ensure the fairness of the cell users. Therefore, a good scheduling algorithm should take into account both cell throughput and user fairness. .
- the current MAC layer scheduling algorithms mainly have the following three types:
- Max C/I Maximum carrier-to-interference ratio
- the Max C/I scheduling algorithm always assigns resource blocks (RBs) to the C/I maximum, that is, the UE with the best channel conditions.
- RBs resource blocks
- the biggest advantage of this algorithm is that it can obtain the maximum cell data throughput and resources. Utilization, but unfavorable is that the fairness of resource allocation is not considered at all, resulting in UEs with poor channel conditions being blocked for a long time. For example, a UE at the cell edge may not be as good as a UE at the cell center because the C/I is not as good as the UE at the cell center. There is no chance of being assigned an RB at all;
- the core of the RR scheduling algorithm is to assume that all UEs have the same scheduling priority, so as to ensure that resources are allocated to all UEs in the system with equal opportunities, so that the UEs occupy radio resources for communication in a certain order. From the perspective of resource occupation, the RR scheduling algorithm is the most fair, but since the channel conditions of the user are not considered, the reliability of the transmission is not high, resulting in extremely low cell throughput and resource utilization.
- the PF scheduling algorithm allocates a priority to each UE in the cell, and at each scheduling moment, the UE with the highest priority is preferentially scheduled.
- the PF scheduling algorithm not only considers the channel time-varying characteristics of the UE, but also ensures the balance between multi-user diversity and fairness of the system, so that the throughput of the system and the fairness of resource allocation can be considered.
- the above three scheduling algorithms only distinguish the scheduling priority of the UE according to the quality of the wireless channel, and do not consider the actual demand of the UE for the resource.
- the actual demand of the UE for resources is not directly related to the quality of the wireless channel.
- the actual demand of the UE for the resource may be reflected from the historical throughput of the UE in the cell, and the historical throughput of the UE in the cell is larger, which indicates that the actual demand of the UE for the resource is greater to some extent. Therefore, an algorithm for measuring the UE scheduling priority according to the historical throughput of the UE in the cell has emerged. If the historical throughput of the UE is higher, the scheduling priority of the UE is also higher.
- the above algorithm for measuring the UE scheduling priority according to the UE's historical throughput in the cell is used.
- the target base station cannot know that the UE is in the source.
- the base station corresponds to the historical throughput in the cell, and the historical throughput of the UE in the corresponding cell of the target base station can be referred to. Therefore, when the UE switches to the target base station, the target base station needs to count the historical throughput of the UE from zero, and cannot be based on the UE.
- the existing historical throughput is used to calculate the scheduling priority of the UE, so that the scheduling of the target base station to the UE may not meet the requirements of the UE for resources, resulting in a decrease in scheduling performance.

对于MAC层调度算法有两个重要的设计参数：一个是吞吐量，另一个是公平性。吞吐量一般是指单位时间内传输的数据量，公平性则是指在一段时间内小区所有的用户设备(User Equipment，UE)是否都获得了一定的服务机会。MAC层调度算法的目的就是利用UE的信道时变特性，获得多用户分集增益，提高***的总体吞吐量，保证小区用户公平性，因此一个好的调度算法应该同时兼顾小区吞吐量和用户公平性。
根据公平性的级别不同，目前的MAC层调度算法主要有以下三类：
最大载干比(C/I)调度算法(简称Max C/I算法)
Max C/I调度算法总是将资源块(Resource Block，RB)优先分配给C/I最大，即信道条件最好的UE，这种算法最大的好处是能够获得最大的小区数据吞吐量和资源利用率，但不利的是根本不考虑资源分配的公平性问题，从而导致信道条件不好的UE会被长期阻塞，例如处在小区边缘的UE由于C/I不如处于小区中心的UE，则可能一点被分配RB的机会都没有；
轮询(RoundRobin，RR)调度算法
RR调度算法的核心是假设所有UE具有相同的调度优先级，从而保证以均等的机会为***中所有UE分配资源，使UE按照某种确定的顺序占用无线资源进行通信。从占用资源的角度来说，RR调度算法是最公平的，但由于没有考虑到用户信道状况的不同，因此传输的可靠性并不高，导致小区吞吐量和资源利用率极低。
正比公平(Proportional Fair，PF)调度算法
PF调度算法为小区内每个UE都分配了一个优先级，在每一个调度时刻，会优先调度优先级别最高的UE。PF调度算法不仅考虑到UE的信道时变特性，还保证了***多用户分集和公平性之间的平衡，因此能够兼顾***的吞吐量和资源分配的公平性。
但是，上述三种调度算法都只根据无线信道的好坏情况来区分UE的调度优先级，而并未考虑到UE对资源的实际需求。事实上，UE对资源的实际需求与无线信道的好坏并无直接的关系。通常，UE对资源的实际需求可以从UE在小区内的历史吞吐量反映出来，UE在小区内的历史吞吐量越大，一定程度上说明UE对资源的实际需求越大。因此，目前一种根据UE在小区内历史吞吐量衡量UE调度优先级的算法应运而生，若UE的历史吞吐量越高，则该UE的调度优先级也越高。
然而，采用上述根据UE在小区内历史吞吐量衡量UE调度优先级的算法，当对UE进行小区切换，即将该UE的接入从源基站切换至目标基站时，由于目标基站无法获知UE在源基站对应小区内的历史吞吐量，又无UE在目标基站对应小区内的历史吞吐量可参考，因此在UE切换至目标基站的最初，目标基站需要从零统计UE的历史吞吐量，无法根据UE已有的历史吞吐量来计算UE的调度优先级，使目标基站对UE的调度可能无法满足UE对资源的需求，造成调度性能下降。

应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
第一实施例
参阅图1所示，为本发明第一实施例提供的一种用户设备(User Equipment，简称UE)调度方法的流程示意图。在本实施例中，该用户设备调度方法包括以下步骤：
步骤S1，在UE从源基站切换至目标基站的过程中，该源基站将该UE接入在源基站中的历史吞吐量信息传递至该目标基站；
步骤S2，当UE切换至目标基站后，该目标基站根据该历史吞吐量信息
确定该UE的调度优先级；
步骤S3，目标基站根据该调度优先级调度该UE。
通过本实施例的用户设备调度方法，可以在UE从源基站切换至目标基站时，使目标基站可以根据UE的历史吞吐量计算UE的调度优先级，从而提高目标基站对UE的调度性能。
下面针对上述各步骤的实现细节进行进一步的描述：
步骤S1所述的UE例如可以是智能手机、平板电脑或者其他类似的移动通信电子装置。
在一个实施例中，例如图2所示，所述UE 1、源基站2和目标基站3之间可以参照LTE(Long Term Evolution，长期演进)标准***的架构进行连接。可选的，LTE***由演进分组核心网(全称Evolved Packet Core，EPC)4、演进型的统一陆地无线接入网络(Evolved Universal Terrestrial Radio Access Network，E-UTRAN)和UE 1组成。其中，所述E-UTRAN中包括所述源基站2和目标基站3，源基站2和目标基站3之间通过X2接口进行互连，而源基站2和目标基站3又分别通过S1接口与核心网4相连。
通常UE 1通过接入到所述E-UTRAN中的一个基站中进行无线通信，当处于连接状态的UE 1从一个小区移动到另一个小区时，为了使UE 1的通信不中断，需要对UE 1进行所接入基站的切换操作。此时，UE 1在切换前所接入的基站即为所述源基站2，在切换后所接入的基站即为所述目标基站3。将UE 1从源基站2切换到目标基站3的过程包括以下步骤：
步骤a，源基站2根据UE 1的测量上报判定需要将UE 1向目标基站3进行切换；
步骤b，源基站2向目标基站3发送切换请求，请求将UE 1切换至目标基站3；
步骤c，目标基站3判定同意接入UE 1后，向源基站2发送同意切换的切换响应；
步骤d，源基站2接收到所述切换响应后，向UE 1发送连接重配消息；
步骤e，UE 1根据该连接重配消息成功切换至目标基站3时，向目标基
站3发送连接重配完成消息，从而通知目标基站3该UE 1成功接入目标基站3。
由于源基站2与目标基站3之间有直接通过所述X2接口直接互连通信和通过S1接口及核心网4间接互连通信两种方式。因此UE 1在源基站2和目标基站3之间进行切换的方式也对应有两种：一种是信令通过X2接口在源基站2和目标基站3之间直接传递的切换，被称为基于X2接口的切换，另一种是信令通过S1接口和核心网4在源基站2和目标基站3之间间接传递的切换，被称为基于S1接口的切换。
因此，若UE 1在源基站2和目标基站3之间采用所述基于X2接口的切换方式，则在所述步骤b中，源基站2向目标基站3发送切换请求的方式为通过X2接口直接向目标基站3发送。而在所述步骤c中，目标基站3向源基站2发送同意切换的切换响应的方式也为通过X2接口直接向源基站2发送。
若UE 1在源基站2和目标基站3之间采用所述基于S1接口的切换方式，则在所述步骤b中，源基站2向目标基站3发送切换请求的方式为将该切换请求经过所述S1接口和核心网4间接向目标基站3发送。而在所述步骤c中，目标基站3向源基站2发送同意切换的切换响应的方式也为经过所述S1接口和核心网4间接向源基站2发送。
步骤S1所述UE 1接入在源基站2中的历史吞吐量信息是指当判定需要将UE 1从源基站2切换至目标基站3的时刻，源基站2所统计得到的该UE 1的历史吞吐量信息。该历史吞吐量信息例如包括UE 1在设定的时间窗内的平均吞吐量，UE 1当前的瞬时吞吐量，UE 1在所述设定的时间窗内的最大平均吞吐量和最大瞬时吞吐量，等等。通常在一定的时间窗内，所述UE 1的最大平均吞吐量和最大瞬时吞吐量可以认为是常量，而UE 1在设定的时间窗内的平均吞吐量和UE 1当前的瞬时吞吐量可以认为是变量，该变量可以反映UE所需资源的多少。该历史吞吐量信息可以由源基站2在对UE 1进行介质访问控制(Media Access Control，MAC)层调度时统计得到。通常为了节约空口资源，在传递该历史吞吐量信息前，还需要将所得到的历史吞吐量信息进行编码，从而降低该历史吞吐量信息的数据量。
根据上述将UE 1从源基站2切换到目标基站3的过程描述，步骤S1中
源基站2将UE 1接入在源基站时的历史吞吐量信息传递至目标基站3的方法可以包括以下三种：
第一种：源基站2将该历史吞吐量信息经过UE 1传递至目标基站3。具体而言，经过步骤a，源基站2判定需要将UE 1切换至目标基站3，且切换方式为基于S1接口的切换或基于X2接口的切换，再经过步骤b和步骤c，源基站2向目标基站3发送切换请求，并且接收到目标基站3发送的同意切换的切换响应后，源基站2向UE 1发送携带有该历史吞吐量信息的连接重配消息，然后UE 1根据该连接重配消息成功切换至目标基站3时，向目标基站3发送携带有该历史吞吐量信息的连接重配完成消息，从而将该历史吞吐量信息传递至目标基站3。在一个实施例中，如图3所示，该连接重配消息可以为相关RRC(Radio Resource Control，无线资源控制协议)连接中常用的RRC连接重配置消息RRCConnectionReconfiguration，该连接重配完成消息可以为RRC连接重配置完成消息RRCConnectionReconfigurationComplete。
第二种：源基站2将该历史吞吐量信息经过核心网4传递至目标基站3。具体而言，经过步骤a，源基站2判定需要将UE 1切换至目标基站3，且切换方式为基于S1接口的切换时，经过步骤b，源基站2经过所述核心网4向目标基站3发送携带有该历史吞吐量信息的切换请求，从而将该历史吞吐量信息传递至目标基站3。
第三种：源基站2将该历史吞吐量信息经过X2接口直接传递至目标基站3。具体而言，经过步骤a，源基站2判定需要将UE 1切换至目标基站3，且切换方式为基于X2接口的切换时，经过步骤b，源基站2经过所述X2接口直接向目标基站3发送携带有该历史吞吐量信息的切换请求，从而将该历史吞吐量信息传递至目标基站3。
步骤S2中目标基站3根据该历史吞吐量信息确定UE 1的调度优先级，具体而言，步骤S2可以将所述历史吞吐量信息作为UE 1接入目标基站3时历史吞吐量的初始值，利用根据历史吞吐量确定UE 1调度优先级的算法，从而计算出UE 1在目标基站3中初始的调度优先级。例如，假设该历史吞吐量信息包括UE 1在设定的时间窗内的平均吞吐量R(t)，UE 1当前的瞬时吞吐量r(t)，UE 1在所述设定的时间窗内的最大平均吞吐量Rmax和最大瞬时吞吐
量rmax，则该根据历史吞吐量确定用户设备调度优先级的算法可以为根据上述R(t)、r(t)、Rmax和rmax计算出参考因子P，该参考因子P可以反映当R(t)或r(t)越大，则参考因子P越大，并进一步根据该参考因子P确定UE 1的调度优先级越高。该参考因子P的计算公式例如如下：
P＝R(t)*r(t)/(Rmax*rmax)。
当然，UE 1的调度优先级也可以根据其他公式得到，例如指数或对数型公式，但要符合若该历史吞吐量信息指示的历史吞吐量越高，则目标基站确定该用户设备的调度优先级越高的原则。
步骤S3中目标基站3根据所确定的调度优先级调度UE 1。该调度优先级是根据UE 1接入在源基站2时的历史吞吐量信息确定的，根据上述原则可知，若UE 1接入在源基站2时的历史吞吐量越高，则UE 1接入在目标基站3时的调度优先级也越高，从而使UE 1从源基站2切换至目标基站3时，目标基站3可以根据UE1的历史吞吐量计算UE1的调度优先级，从而提高目标基站3对UE1的调度性能。
