在无线网络中，为保证用户设备(User Equipment，UE)能够接入无线网络并获取所需的服务，在UE接入无线网络时，可以为UE配置网络节点(例如无线网络节点、控制面节点和用户面节点等)和服务质量(Quality of Service，QoS)参数。
在为UE配置网络节点的过程中，以为UE配置网关为例，通常可以根据UE在无线网络中的位置和无线网络中的网关的状态，为UE配置网关。具体的，移动性管理实体(Mobility Management Entity，MME)接收域名系统(Domain Name System，DNS)服务器发送的UE所在区域的所有网关的能力和所有网关的负载大小，然后MME根据这些网关的能力和这些网关的负载大小，在这些网关中为UE配置网关，例如MME为UE配置这些网关中能力最强且负载最小的网关。
然而，上述方法中，由于MME根据UE在无线网络中的位置和无线网络中的网关的状态为UE配置的网关可能不能满足UE的业务需求，例如，网关的传输速率可能低于UE传输业务所需要的传输速率，因此可能导致UE的业务无法顺利地传输。

具体实施方式
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
本发明的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一控制面节点和第二控制面节点等是用于区别不同的控制面节点，而不是用于描述控制面节点的特定顺序。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本发明的描述中，除非另有说明，“多个”的含义是指两个或两个以上。例如，多个无线性能参数是指两个或两个以上的无线性能参数。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行详细地描述。
首先对本发明实施例提供的一种终端接入网络的方法、装置及系统中涉及的一些概念进行解释说明。其中，本发明实施例中的网络可以为无线网络。
UE的无线接入能力等级：是指UE接入网络时采用的无线性能参数的等级。UE的每个无线接入能力等级对应UE的多个无线性能参数，该多个无线性能参数能够表示UE在网络中的上行传输的传输能力和下行传输的传输能力。示例性的，UE的无线接入能力等级可以包括等级1(Category 1，Cat 1)至Cat 12、Cat 0、Cat M1和Cat NB1，与每个无线接入能力等级对应的多个无线性能参数可以包括UE的下行峰值速率、上行峰值速率、天线数量、双工模式、接收带宽以及发射功率等。如表1所示，为UE的无线接入能力等级 和UE的多个无线性能参数的示例性的对应关系。
表1
Figure PCTCN2016113896-appb-000001
本发明实施例中，UE的无线接入能力等级还可以用于指示UE的类型。其中，Cat 1至Cat 12对应采用了长期演进(Long Term Evolution，LTE)技术的无线终端，例如智能手机终端；Cat 0、Cat-M1和Cat NB对应于几类物联网终端，其中，Cat 0对应采用了机器类通信(Machine-type Communications，MTC)技术的终端，例如配置有MTC模块的智能水表终端，Cat M1对应于采用了增强型机器类通信(enhance Machine-type Communications，eMTC)技术的终端，例如配置了eMTC模块的智能手表，Cat NB对应于采用了窄带物联网(Narrow Band Internet of Things，NB-IoT)技术的终端，例如配置了NB-IoT通信模块的智能电表终端。
服务质量(Quality of Service，QoS)：是指网络能够为网络中通信的设备(例如UE)提供服务的能力。
QoS参数：是指可以体现网络中服务质量的优劣的参数。在不同的网络中，QoS参数中可能包括不同的参数项。例如，在第三代 (3rd Generation，3G)移动通信网络(以下均简称为3G网络)中，QoS参数可以包括：最大比特速率(Maximum Bit Rate，MBR)、最大传输单元、传输差错率、传输时延、保证比特速率(Guaranteed Bit Rate，GBR)、数据流处理优先级等。在第四代(4th Generation，4G)移动通信网络(以下均简称为4G网络)中，QoS参数可以包括服务质量分类标识(QoS Class Identifier，QCI)、分配和保持优先级(Allocation and Retention Priority，ARP)、GBR、MBR、每个接入点名称(Access Point Name，APN)的最大汇聚比特速率(Aggregation Maximum Bit Rate，AMBR)，即APN-AMBR、UE的最大汇聚比特速率(UE-AMBR)等参数项。在未来的第五代(5th Generation，5G)移动通信网络(以下均简称为5G网络)中，QoS参数可能包括上述3G和/或4G网络中的QoS参数(例如，包括与3G网络和/或4G网络中相同的QoS参数，或者包括与3G和/或4G网络中具有相同功能而名称不同的QoS参数等)，或者其他的与3G和/或4G网络中功能不同的QoS参数，例如最大数据流比特速率、优先级、传输时延、传输差错率等。
示例性的，以4G网络为例，对上述QoS参数中的各个参数项作示例性的说明。对于4G网络中的QoS参数，其中，QCI用于表示数据包的转发方式，例如数据包的调度权重(即数据包的调度优先级)和队列管理门限(如数据包队列的长度)等。ARP用于在网络中资源不足，且要建立新的承载时，网络中的节点(如网关或基站)会根据ARP来决定是否在删除已经建立的承载之后再建立新的承载(例如，删除已经建立的优先级较低的承载，并建立新的优先级较高的承载)，还是拒绝建立新的承载。GBR指在网络中建立的承载为GBR承载，且网络资源不足时能够为UE提供的保证业务传输的传输速率。MBR指能够为UE提供的最大的传输速率，可以用于限制UE的业务的传输速率。APN-AMBR指对于一个APN上所有的非保证速率(None Guaranteed Bit Rate，Non-GBR)承载的传输速率的总和的最大值，通常，网络中可能有多个APN，每个APN都对 应一个APN-AMBR。UE-AMBR是指对于一个UE的所有APN上所有的Non-GBR承载的传输速率的总和。
通常，当终端设备接入网络时，以该终端设备为UE为例，可以通过为UE配置网络节点(例如无线网络节点、控制面节点和用户面节点等)和QoS参数使得UE能够接入网络并获取所需的服务。在为UE配置网络节点的过程中，以为UE配置网关为例，通常MME可以为UE配置UE所在区域的所有网关中能力最强且负载最小的网关。然而，MME按照该方法为UE配置的网关可能并不能满足UE的业务需求，如此可能导致UE的业务无法顺利地传输。
为了解决上述问题，本发明实施例提供一种终端接入网络的方法、装置及系统。当UE接入网络时，在为UE配置接入信息(例如控制面节点、用户面节点和QoS参数等中的至少一项)的过程中，网络中为UE提供服务的网络设备可以首先获取UE的无线接入能力等级，然后网络设备再根据UE的无线接入能力等级，为UE配置满足UE的无线接入能力等级的接入信息，从而UE可以根据该接入信息接入该网络(即该网络设备所在的网络)。与现有技术相比，本发明实施例提供的终端接入网络的方法中，由于网络设备可以根据UE的无线接入能力等级为UE配置满足UE的无线接入能力等级的接入信息，而满足UE的无线接入能力等级的接入信息可以使得UE顺利地接入网络并且能够满足UE的业务需求，因此能够保证UE的业务顺利地传输。
需要说明的是，本发明实施例中，网络设备为UE配置UE接入网络的接入信息之后，UE即可根据该接入信息接入该网络设备所在的网络。
本发明实施例提供的终端接入网络的方法及装置可以应用于无线通信系统中。参考图1，为本发明实施例提供的一种无线通信系统的架构示意图。如图1所示，该无线通信系统可以包括：UE 10、RAN设备11、控制面节点12、用户面节点13以及策略功能设备14等。其中，UE 10与RAN设备11连接，RAN设备11与控制节点 12和用户节点13连接，用户面节点13可以与控制面节点12和策略功能设备14连接，用户面节点用户面节点13和策略功能设备14均与核心网连接。RAN设备11可以为基站；控制面节点12可以为MME，也可以为服务通用分组无线服务技术(General Packet Radio Service，GPRS)支持节点(Serving GPRS Support Node，SGSN)，也可以为接入和移动功能(Access and Mobility Function，AMF)设备；用户面节点13可以为网关(包括服务网关(Serving Gateway，SGW)和分组数据网关(Packet Data Network Gateway，PGW))，也可以为用户面功能(User Planel Function，UPF)。在该无线通信系统中，RAN设备11、控制面节点12、用户面节点13和策略功能设备14为UE 10提供服务，UE可以通过RAN设备与其他设备(例如控制面节点12、用户面节点13和策略功能设备14)之间传输数据，控制面节点12具有接入控制、移动性管理、承载管理、用户面节点的选择等功能，用户面节点13具有转发数据、分配UE的IP地址等功能。在实际应用中上述各个设备之间的连接可以为无线连接，为了方便直观地表示各个设备之间的连接关系，图1中采用实线示意。

Q1、第二控制面节点将该至少一个用户面节点中任意一个用户面节点作为第一用户面节点配置UE。
Q2、第二用户面节点将至少一个用户面节点中负载最小的用户面节点作为第一用户面节点配置给UE。
需要说明的是，本发明实施例中，由于第二控制面节点从至少一个用户面节点中为UE配置第一用户面节点的方法与上述实施例中第二控制面从多个备选用户面节点中为UE配置第一用户面节点的方法(即上述P1或P2)类似，因此，对于Q1和Q2的具体描述可以参见上述对于P1和P2的相关描述，此处不再赘述。
本发明实施例中，上述第二控制面节点在确定出第一用户面节点，并将第一用户面节点的标识发送给网络中的RAN设备之后，RAN设备可以获知该第一用户面节点是可以为该UE提供服务的用户面节点，从而完成为UE配置第一用户面节点，进而RAN设备可以将该UE的数据通过该第一用户面节点传输到网络中的其他UE。
本发明实施例提供的终端接入网络的方法，当UE接入网络时，在为UE配置第一用户面节点的过程中，网络中为UE提供服务的第二控制面节点可以首先获取UE的无线接入能力等级，然后第二控制面节点再根据UE的无线接入能力等级和网络中UE所在区域的所有用户面节点支持的UE无线接入能力等级，为UE配置支持UE的无线接入能力等级的第一用户面节点，或者第二控制面节点根据UE的无线接入能力等级和网络中UE所在区域的所有用户面节点支持的UE类型，为UE配置支持该UE的无线接入能力等级指示的UE的类型的第一用户面节点，或者，第二控制面节点根据UE的无线 接入能力等级和网络中UE所在区域的所有用户面节点支持的峰值速率，为UE配置支持该UE的无线接入能力等级指示的UE的峰值速率的第一用户面节点。与现有技术相比，本发明实施例提供的终端接入网络的方法中，由于第二控制面节点为UE配置的支持UE的无线接入能力等级、支持该UE的无线接入能力等级指示的UE的类型或支持该UE的无线接入能力等级指示的UE的峰值速率的第一用户面节点可以使得UE顺利地接入网络，因此可以保证UE的业务顺利地传输。
场景三：为UE配置QoS参数
本发明实施例中，UE接入网络时，当接入信息为QoS参数时，网络设备为策略功能设备或控制面节点(例如第二控制面节点)，以接入信息为第一QoS参数为例，该第一QoS参数可以包括第一子QoS参数和第二子QoS参数中的至少一种。第一子QoS参数可以包括优先级，第二子QoS参数可以包括UE的最大比特速率。由于网络设备(即策略功能设备或控制面节点)为UE配置第一子QoS参数和第二子QoS参数的方法不同，因此本发明实施例分别以网络设备为UE配置第一子QoS参数和第二子QoS参数为例对本发明实施例提供的UE接入网络的方法进行说明。
需要说明的是，本发明实施例中，上述策略功能设备为UE配置第一子QoS参数的方法与控制面节点为UE配置第一子QoS参数的方法是类似的，本发明实施例以网络设备为策略功能设备，接入信息为第一子QoS参数中的优先级为例，对本发明实施例提供的终端接入网络的方法进行示例性的说明。
结合图5，如图14所示，上述图5所示的S101-S102可以替换为S401-S403，即在场景三中，策略功能设备为UE配置第一子QoS参数可以通过S401-S403实现。具体的，本发明实施例提供的终端接入网络的方法可以包括：
S401、策略功能设备获取UE的无线接入能力等级。
对于UE的无线接入能力等级的具体描述，可以参见上述实施 例(对UE的无线接入能力等级的概念介绍)中对UE的无线接入能力等级的相关描述，此处不再赘述。
结合图14，如图15所示，本发明实施例中，上述图14所示的S401具体可以通过S401a-S401c实现：
S401a、第二控制面节点获取UE的无线接入能力等级。
对于S401a的具体描述，可以参见上述实施例的场景二中对于S301的相关描述，此处不再赘述。
S401b、第二控制面节点向策略功能设备发送UE的无线接入能力等级。
S401c、策略功能接收控制面节点发送的UE的无线接入能力等级。
本发明实施例中，第二控制面节点可以通过用户面节点将UE的无线接入能力等级发送给策略功能设备，即第二控制面节点将UE的无线接入能力等级发送给用户面节点，用户面节点接收到第二控制面节点发送的UE的无线接入能力等级之后，用户面节点将该UE的无线接入能力等级发送给策略功能设备。
需要说明的是，本发明实施例中，上述S401b和S401c中的用户面节点可以为上述实施例的场景二中为UE配置的第一用户面节点，也可以为网络中能够为UE提供服务的其他用户面节点，本发明实施例不作具体限定。
本发明实施例中，策略功能设备获取到UE的无线接入能力等级之后，该策略功能设备可以根据UE的无线接入能力等级为UE配置优先级。
S402、策略功能设备确定与UE的无线接入能力等级对应的优先级。
S403、策略功能设备为UE配置优先级。
本发明实施例中，在上述第二控制面节点中预先保存有多个UE的无线接入能力等级与多个UE的优先级之间的对应关系的信息，当第二控制面节点获取UE的无线接入能力等级之后，第二控制面 节点可以根据UE的无线接入能力等级和该对应关系的信息，从该对应关系的信息中确定与该UE的无线接入能力等级对应的UE的优先级，并将该优先级配置给UE。
可选的，本发明实施例中，上述UE的优先级可以包括不同种类的优先级。例如，在4G网络中，UE的优先级可以包括QCI优先级和ARP。可以理解的是，对于根据UE的无线接入能力等级为UE配置QCI优先级或ARP的方法均可以通过上述S401-S403实现。
可选的，本发明实施例中，也可以由第二控制面节点为UE配置优先级，第二控制面节点为UE配置优先级的方法可以参见上述S401-S403所述的方法，本发明实施例不再赘述。
本发明实施例提供的终端接入网络的方法，当UE接入网络时，在为UE配置第一子QoS参数(即优先级)的过程中，网络中为UE提供服务的策略功能设备或第二控制面节点可以首先获取UE的无线接入能力等级，然后策略功能设备或第二控制面节点根据UE的无线接入能力等级，为UE配置与该UE的无线接入能力等级对应的第一子QoS参数。与现有技术相比，本发明实施例提供的终端接入网络的方法中，由于策略功能设备或第二控制面节点为UE配置的与该UE的无线接入能力等级对应的第一子QoS参数可以使得UE顺利地接入网络，因此可以保证UE的业务顺利地传输。
需要说明的是，本发明实施例中，上述策略功能设备为UE配置第二子QoS参数的方法与控制面节点为UE配置第二子QoS参数的方法是类似的，本发明实施例以网络设备为策略功能设备，接入信息为第二子QoS参数中的UE的最大比特速率为例，对本发明实施例提供的终端接入网络的方法进行示例性的说明。
结合图5，如图16所示，上述S101-S102可以替换为S501-S503，即在场景三中，策略功能设备为UE配置第二子QoS参数可以通过S501-S503实现。具体的，本发明实施例提供的终端接入网络的方法可以包括：
S501、策略功能设备获取UE的无线接入能力等级。
本发明实施例中，UE的无线接入能力等级可以指示UE的峰值速率，即策略功能设备获取到UE的无线接入能力等级之后，该策略功能设备可以获知该UE的峰值速率。
对于S501的具体描述，可以参见上述对于S401的相关描述，此处不再赘述。
S502、策略功能设备确定UE的最大比特速率。
S503、策略功能设备为UE配置最大比特速率。
本发明实施例中，策略功能设备获取到UE的无线接入能力等级之后，该策略功能设备可以根据UE的无线接入能力等级指示的UE的峰值速率确定最大比特速率。具体的，策略功能设备将小于或等于该UE的无线接入能力等级指示的UE的峰值速率的速率确定为最大比特速率。
可选的，本发明实施例中，具体可以根据UE的实际业务的需求为UE确定一个小于或等于该UE的无线接入能力等级指示的UE的峰值速率的速率作为UE的最大比特速率。
可选的，本发明实施例中，上述策略功能设备为UE配置最大比特速率时，还可以通过比较UE的无线接入能力等级指示的UE的峰值速率与UE的签约信息中预设的最大比特速率(以下称为第一比特速率)，并将UE的无线接入能力等级指示的UE的峰值速率与第一比特速率中较小的一个作为最大比特速率配置给UE。
可选的，本发明实施例中，上述UE的最大比特速率可以包括各种不同的最大比特速率。例如，在4G网络中，最大比特速率可以包括MBR、APN-AMBR和UE-AMBR。可以理解的是，对于根据UE的无线接入能力等级为UE配置MBR、APN-AMBR和UE-AMBR的方法均可以通过上述S501-S503实现。
可选的，本发明实施例中，当最大比特速率为UE-AMBR时，策略功能设备可以首先计算其确定的多个APN-AMBR之和(以下均称为第二比特速率)，然后策略功能设备通过比较UE的无线接入能力等级指示的UE的峰值速率、UE的签约信息中预设的最大比特速 率(即上述第一比特速率)和第二比特速率，将UE的无线接入能力等级指示的UE的峰值速率、第一比特速率和第二比特速率最小的一个作为最大比特速率配置给UE。
可选的，本发明实施例中，还可以由第二控制面节点为UE配置最大比特速率，第二控制面节点为UE配置最大比特速率的方法可以参见上述S501-S503所述的方法，本发明实施例不再赘述。
本发明实施例提供的终端接入网络的方法，当UE接入网络时，在为UE配置第二QoS参数(即UE的最大比特速率)的过程中，网络中为UE提供服务的策略功能设备或第二控制面节点可以首先获取UE的无线接入能力等级，然后策略功能设备或第二控制面节点根据UE的无线接入能力等级指示的UE的峰值速率，确定出最大比特速率，并为UE配置该最大比特速率。与现有技术相比，本发明实施例提供的终端接入网络的方法中，由于策略功能设备或第二控制面节点为UE配置的满足UE的无线接入能力等级的第二子QoS参数可以使得UE顺利地接入网络，因此可以保证UE的业务顺利地传输。
