Description

覆盖增强CE功能的实现方法及设备 技术领域
本发明实施例涉及物联网技术领域，尤其涉及一种覆盖增强CE功能的实现方法及设备。
背景技术
随着物联网技术的快速发展，为支持不同场景的物联网应用(如地下室、管线等弱覆盖场景)，第三代合作伙伴计划(3rd Generation Partnership Project，简称3GPP)引入了覆盖增强(Coverage enhancement，简称CE)技术。但终端并不总是位于覆盖比较差的地方，因此通过划分不同的覆盖等级(3GPP TR23.720中称为Coverage Enhancement Level，3GPP TS 36.300中称为Coverage Class)，如图1A所示(图1A为CE等级划分示意图)，不同的CE等级采用不同的调制编码方式和不同的重复/传播方式(例如CE等级值越大，则表示终端的覆盖越差，所需重传次数越多，对应的调制编码方式可靠性要求更高)，以保障覆盖的前提下，可以提高系统的容量(如系统能同时接入的用户数或最大传输速率等)、节省终端的电池耗电和降低时延。
通常情况下，终端的CE等级可以是静态的或者动态的；其中，对于静态CE等级，则在CE等级一旦选定之后，一定时间内不会再改变，主要适用于比较固定、低移动性的终端，例如水表、电表等终端(信号覆盖不会频繁改变)；对于动态CE等级，则随着终端的移动性，信号覆盖可能会频繁改变(即CE等级可能需要对应调整)。
传统CE功能的实现方式中，对于动态CE等级，终端在某个小区所使用的CE等级通常是终端根据自身的无线信道质量变化来调整CE等级，并通过该CE等级对应的无线信道资源接入网络(即终端仅根据自身的无线信道质量使用CE功能)，例如：可预先设定多个无线信道质量门限值，若终端的无线信道质量小于等于预设门限值1，则终端使用CE等级3；若终端的无线信道质量大于预设门限值1且小于等于预设门限值2(预设门限值2大于预设门限值1)，则终端使用CE等级2。但由于覆盖增强技术采用多次重传等技术，每次重传 都会消耗额外的无线信道资源，尤其对于终端数量较多且带宽较窄的物联网应用场景，可供接入的无线信道资源非常有限；因此，终端仅根据自身的无线信道质量使用CE功能，并不能保证终端对无线信道资源的合理利用，无线信道资源的使用效率较低。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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清楚地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请中涉及的终端，即用户设备(User Equipment，简称UE)，可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(PCS，Personal Communication Service)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL，Wireless Local Loop)站、个人数字助理(PDA，Personal Digital Assistant)等设备。 无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
本申请中涉及的第一无线接入网节点和第二无线接入网节点，均可以为独立设置在无线接入网侧(Radio Access Network，简称RAN)的设备，例如：基站、无线网络控制器(Radio Network Controller，简称RNC)等，也可以为无线接入网侧上述各种设备中的一个功能模块。可选地，第一无线接入网络节点为终端当前接入的无线接入网络节点；第二无线接入网络节点为终端接入的历史无线接入网络节点(即终端在接入第一无线接入网络节点之前，所接入的无线接入网络节点)。
基站(例如，接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(Base Transceiver Station，简称BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，本申请并不限定。
本申请中涉及的核心网节点可以为MME。
本申请实施例主要适用于采用CE技术的应用场景。本申请实施例主要应用于演进分组系统(Evolved Packet System，简称EPS)，EPS网络架构采用端到端全互联网协议(Internet Protocol，简称IP)组网和扁平化网络结构，并充分考虑了和现有2G/3G网络的兼容性。图1B为EPS网络架构示意图，如图1B所示，主要网络实体包括：演进的通用陆基无线接入网(Evolved universal terrestrial radio access network，简称EUTRAN)、移动性管理实体(Mobility Management Entity，简称MME)、服务网关(Serving Gateway，简称S-GW)以及分组数据网络网关(Packet Data Network Gateway，简称P-GW)等。1)EUTRAN由多个基站组成的网络，用于实现无线物理层功能、资源调度和无线资源管理、无线接入控制以及移动性管理功能；其中，基站 通过用户面接口S1-U和S-GW相连，用于传送用户数据；基站通过控制面接口S1-MME和MME相连，采用S1-AP协议实现无线接入承载控制等功能；基站通过LTE-Uu接口和终端相连；2)MME主要用于负责用户即会话管理的所有控制平面功能，包括NAS信令及安全、跟踪区的管理以及P-GW与S-GW的选择等；3)S-GW主要用于负责终端的数据传输、转发以及路由切换等，并作为终端在基站之间切换时的本地移动性锚定点(对于每一个终端，每个时刻仅有一个S-GW为之服务)；4)P-GW作为PDN连接的锚定点，用于负责终端的IP地址分配、终端的数据报文过滤、速率控制以及生成计费信息等；5)归属签约用户服务器(Home Subscriber Server，简称HSS)用于存储用户签约信息的数据库；6)服务GPRS支持节点(Serving GPRS Support Node，简称SGSN)主要用于2G/3G终端的数据传输、转发以及路由切换等；7)策略与计费规则功能单元(Policy and Charging Rules Function，简称PCRF)主要用于业务的服务质量(Quality of Service，简称QoS)策略控制以及计费策略控制。
考虑到每次CE需要消耗更多无线信道资源，为了保证终端对无线信道资源的合理利用，本申请实施例中，网络侧通过根据CE授权信息控制终端使用CE功能(即并非所有终端都能使用CE功能，例如：只有签约了CE功能的终端才能使用，或者CE优先级更高的集团用户的终端才能使用等)，或终端自身根据CE授权信息使用CE功能，从而确保终端能够在授权范围内恰当使用CE功能，从而提高无线信道资源的使用效率。
下面结合附图通过具体实施例对本发明实施例提供的覆盖增强CE功能的实现方法及设备进行详细说明。
图2为本发明覆盖增强CE功能的实现方法实施例一的流程示意图。如图2所示，本实施例的方法可以包括：
S201、第一无线接入网络节点获取终端的CE授权信息。
本步骤中，在终端根据自身的无线信道质量确定CE等级并根据该CE等级对应的无线资源发起随机接入请求后，第一无线接入网络节点(可选地，第一无线接入网络节点为终端当前接入的基站)获取终端的CE授权信息，可选地，CE授权信息包括以下至少一种：CE指示信息、授权CE等级范围，当然，CE授权信息还可包括其它信息(例如CE状态等，CE状态CE状态用 于指示动态CE或者静态CE)，本申请实施例中对此并不作限制；其中，CE指示信息用于指示终端是否允许使用CE功能，授权CE等级范围用于指示终端所允许使用的CE等级范围。可选地，授权CE等级范围可以是一个具体的CE等级限制(例如终端允许使用的CE等级不超过CE等级3)；或者，授权CE等级范围也可以是一个CE模式(例如，假设CE模式A表示终端可以使用CE等级0和CE等级1，CE模式B表示终端可以使用CE等级2和CE等级3，若授权CE等级范围为CE模式A，即表示终端允许使用的CE等级不超过CE等级1)。可选地，授权CE等级范围还可以为其它表示形式，本申请实施例中对此并不作限制。
可选地，第一无线接入网络节点获取终端的CE授权信息可通过以下几种可实现方式：
第一种可实现方式：第一无线接入网络节点从本地获取已保存的终端的CE授权信息。可选地，若第一无线接入网络节点中已保存该终端的CE授权信息，则第一无线接入网络节点直接从本地获取该终端的CE授权信息；可选地，第一无线接入网络节点中已保存的该终端的CE授权信息可以为：第一无线接入网络节点在该终端接入之前从核心网节点(如该终端当前附着的MME或者之前附着的MME)获取该终端的CE授权信息并保存在本地，或者第一无线接入网络节点在该终端接入之前从该终端的历史无线网络接入节点(如第二无线网络接入节点)获取该终端的CE授权信息并保存在本地(可选地，可以为第二无线网络接入节点在接收到第一无线接入网节点发送的用于请求获取CE授权信息的消息后返回的，或者为第二无线网络接入节点在无线网络接入节点切换过程中主动发送给第一无线网络接入节点)。当然，第一无线接入网络节点中已保存的该终端的CE授权信息还可以通过其它方式获取，本申请实施例中对此并不作限制。

第三种可实现方式：第一无线接入网络节点接收核心网节点(如该终端当前附着的MME或者之前附着的MME)发送的终端的CE授权信息。可选地，第一无线接入网络节点在接收到终端发送的随机接入请求后，通过向核心网节点请求该终端的CE授权信息，并接收核心网节点返回的该终端的CE授权信息。对应地，核心网节点在接收到第一无线接入网络节点发送的用于请求CE授权信息的请求消息后，核心网节点根据终端的签约信息(如包括终端是否签约CE功能和/或终端签约的CE等级范围等)以及CE能力信息(如终端是否支持CE功能)，确定终端的CE授权信息，并将该终端的CE授权信息发送给第一无线接入网络节点，以使第一无线接入网络节点根据CE授权信息确定终端的CE等级是否符合授权。可选地，签约信息和/或CE能力信息还可能包括其它信息，本申请实施例中对此并不作限制。

可选地，在第四种可实现方式中，若CE授权辅助信息包括：终端签约的CE等级范围，第一无线接入网络节点根据CE授权辅助信息和/或本地策略确定授权CE等级范围；其中，本地策略包括以下至少一种：无线信道资源支持CE信息以及无线信道资源使用状态，当然，本地策略还可包括其它信息，本申请实施例中对此并不作限制。例如，若CE授权辅助信息指示终端已签约CE等级范围不超过CE等级3，但由于支持CE功能的剩余可用无线信道资源不足以支持CE等级3，则第一无线接入网络节点仍然拒绝终端使用CE等级3(即授权CE等级范围用于指示终端允许使用的CE等级低于CE等级3)。
