Description

一种多无线接入网络下提供业务与接受业务的方法及设备
本申请要求在2015年6月10日提交中国专利局、申请号为201510316287.3、发明名称为“一种多无线接入网络下提供业务与接受业务的方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域，特别涉及一种多无线接入网络下提供业务与接受业务的方法及设备。
背景技术
图1为双连接无线资源控制(Radio Resource Control，RRC)协议架构示意图，如图所示，所谓双连接架构，指用户设备(User Equipment，UE)101同时与两个基站有无线链路(即Uu接口)，其中仅有一个基站中有此UE专用的RRC实体，称为主基站(Master eNB，MeNB)102；另一个基站没有此UE专用的RRC实体，称为辅基站(Secondary eNB，SeNB)103。在MeNB基站下，可以有一组小区为UE提供资源用于网络服务，这组服务小区称为主小区组(Master Cell Group，MCG)；同时，在SeNB基站下，也有一组小区为UE提供无线资源用于网络服务，这组服务小区称为辅小区组(Secondary Cell Group，SCG)。
由于仅在主控基站MeNB中有UE专用的RRC实体，因此RRC连接只在UE与MCG之间存在，而在UE与SCG之间没有RRC连接。传输RRC信令消息的信令承载信令无线承载(Signalling Radio Bearer，SRB)只能在UE跟MeNB之间建立。
现有技术的不足在于：在目前的无线通信系统中，无论是长期演进(Long Term Evolution，LTE)双连接架构，还是LTE/无线局域网(Wireless Local Area Network，WLAN)聚合架构，一个用户终端只能同一个接入节点建立无线控制面连接RRC，即使在双连接架构下，UE也仅能跟MeNB建立RRC连接，网络不支持UE同时与多个无线接入技术(Radio Access Technique，RAT)设备接入节点建立RRC连接。为了使不同RAT接入节点之间要能进行协调和数据传输，这要求不同RAT设备间需建立接口，并使用标准协议进行通讯。这就要求所有RAT接入节点都要进行升级，而这将会增加运营商的网络成本。
另外，现有一些双模终端设备可以跟网络建立两条控制连接，但这些双模终端设备从逻辑功能上相当于两个独立的UE实体，其中每个UE仅能跟网络建立一条控制面连接。

具体实施方式
下面结合附图对本发明的具体实施方式进行说明。
未来，随着新一代移动通信系统(5-Generation，5G)的引入，会出现多种无线接入技术长期共存的现象，如5G、4G LTE、WiFi等，如何协同使用各种无线技术，提升网络整体运营效率和用户体验是多RAT协同技术所需要解决的问题。网络可以同时通过多种无线接入技术为用户提供业务，并能够基于用户所接受的业务类型和特点，智能地选择合适的接入技术。另外，要求用户在多个接入网络间的无缝切换，确保在用户移动过程中吞吐量不降低，业务不中断。但是用户以及业务网络无需感知这个过程。
基于此，本发明实施例中提出了一种多无线接入网络下为终端设备提供业务的方案，以及多无线接入网络下接受业务的方案，方案中，用户的终端设备可以实现运营商同时利用多种无线接入技术为用户提供业务，并实现多种无线接入技术间的无缝切换。下面进行说明。
在说明过程中，将分别从终端设备与接入节点侧的实施进行说明，但这并不意味着二者必须配合实施，实际上，当终端设备与接入节点分开实施时，其也各自解决终端设备侧、接入节点侧的问题，只是二者结合使用时，会获得更好的技术效果。

步骤203、通过所述终端设备与该无线接入网络的接入节点建立的控制面连接，为向所述终端设备提供的业务建立数据承载；
步骤204、通过该数据承载向所述终端设备提供业务。
实施中，针对每一个业务，根据每一个业务的承载参数在各无线接入网络中确定与为所述终端设备提供的每一个业务相适应的无线接入网络；针对每一个无线接入网络，通过所述终端设备与该无线接入网络的接入节点建立的控制面连接，为向所述终端设备提供的业务建立数据承载，并通过该数据承载向所述终端设备提供业务。

下面还将通过各实例对如何确定与业务相适应的无线接入网络的实施，此处不再赘述。

该测量报告是用于供网络侧设备确定与业务相适应的无线接入网络的，下面还将通过各实例进行说明，此处不再赘述。
上述方案中，终端设备可同时跟多个RAT建立多个RRC连接，其中每个RAT建立一条控制面连接，不同RAT间的控制面连接彼此独立，网络通过每个RAT的控制面连接控制和管理该RAT的数据承载，以及RAT特定的配置参数。实施中，RAT包括但不限于LTE系统，5G系统等。为更好地理解上述方案的实施，下面对可能的实施环境举一例进行说明。
图4为多连接的网络架构示意图，如图所示，在新一代无线通讯系统(5G)的一种架构中，有一个集中控制实体，称为本地控制中心(Local Control Center，LCC)，和一个集中数据实体，称为本地数据中心(Local Data Center，LDC)，LCC和LDC都连接-到核心网，LDC还连接到因特网(Internet)。
LCC，用于管理终端设备的控制面连接；LDC，用于根据LCC的指示为终端设备建立数据承载，并在该数据承载上传输业务数据。在本例中，管理控制面连接的网络侧设备与管理数据承载的网络侧设备分别由LCC与LDC负责，但是，实施中，控制面连接管理与数据承载管理只是功能上的划分，因此LCC与LDC可以是分离的，也可在一个物理实体设备上。
下面结合实例对具体的实施进行说明。
实施例1：实施中，在终端设备侧，还可以进一步包括：向第一无线接入网络的第一接入节点发起RRC连接请求；根据第一接入节点反馈的指令通过第一无线接入网络的第一接入节点建立网络侧设备与终端设备间的第一控制面连接。
在网络侧设备上，若与终端设备建立的控制面连接是通过第一无线接入网络的第一接入节点建立的与终端设备的控制面连接，与向所述终端设备提供的业务相适应的无线接入网络是第二无线接入网络，且未建立控制面连接时，还可以进一步包括：通过第一接入节点建立的控制面连接指示所述终端设备与第二无线接入网络建立控制面连接；

根据指示向第二无线接入网络的第二接入节点发起RRC连接请求；
根据第二接入节点反馈的指令通过第二无线接入网络的第二接入节点建立网络侧设备与终端设备之间的第二控制面连接；所述接收网络侧设备通过控制面连接发送的建立数据承载的指示，是通过第二控制面连接发送的。
本实施例中，将以LCC、LDC为网络侧设备，终端设备为UE为例，说明在两个RAT之间为UE的业务选择一个与其相适应的RAT，并进行业务的实施方式。例中，UE将分别与RAT1、RAT2建立控制面连接，其中RAT2的控制面连接是根据RAT1的控制面连接的指示来建立的，数据承载是通过RAT2建立的，并通过RAT2提供业务。
图5为多控制连接建立过程实施流程示意图，如图所示，可以包括如下步骤：
步骤501、基于用户的业务要求，UE跟RAT1建立RRC连接，具体实施中，RAT1 可以是4G LTE，也可以是5G系统；
步骤502、RAT 1的接入节点跟LCC，以及LCC跟核心网(Core Network，CN)之间建立该UE特定的控制面连接(或称为信令连接)；
步骤503、RAT1的接入节点为UE设置测量配置；
步骤504、UE跟核心网之间进行鉴权和认证；
步骤505、LCC为UE创建上下文，包含RAT1控制面连接信息；
步骤506、UE上报测量报告，测量报告包括RAT1小区的测量结果，以及对其它RAT邻区的测量结果；
步骤507、UE发起新业务，向网络发送业务承载资源修改请求，要求网络为该业务分配适合的承载资源；
步骤508、在各无线接入网络中确定与向终端设备提供的业务相适应的无线接入网络，本例中，LCC根据所请求业务承载的QoS参数，UE上报的测量结果(包括RAT1小区的无线信号测量结果，及RAT2小区的无线信号测量结果)，以及LCC控制的各RAT小区的无线资源负荷状况，选择合适的无线接入技术为该业务提供数据传输，例中选择的是RAT2；
步骤509、LCC指示UE接入到RAT2，这条消息是通过RAT1的接入节点发送到UE的，消息中可以包含LCC希望UE接入的RAT2小区的系统信息，如物理信道配置，随机接入配置信息等；
步骤510、根据网络侧LCC的指示，UE跟RAT2的接入节点建立RRC连接；
步骤511、RAT 2的接入节点跟LCC以及LCC跟CN之间建立该UE的控制面连接(或称为信令连接)；
步骤512、RAT2的接入节点为UE设置测量配置；
步骤513、LCC更新UE的上下文，保存RAT1控制面连接和RAT2控制面连接信息；
步骤514、LCC分别与RAT2接入节点和LDC进行信令交互，为UE建立该业务的专用数据承载；
步骤515、RAT2接入节点跟UE之间建立无线数据承载；
步骤516、承载建立完成后，UE经RAT2的接入节点跟LDC之间进行业务数据传输。
实施例2：本例中，将说明实施例1的情况下，UE发起实时在线视频业务的实施，例中RAT1为LTE网络，RAT2为5G网络，RAT1的接入节点为LTE宏基站(LTE macro eNB)，RAT2的接入节点为5G节点(5G node)。例中，UE首先经LTE macro eNB跟网络建立一条控制面连接，之后经5G node跟网络建立另一条控制面连接。
图6为实时在线视频业务时多控制连接实施网络环境示意图，如图所示，结合实施例1，在该网络环境下，实施流程可以如下：
1)UE在LTE网络和5G网络的共同覆盖下，UE跟LTE macro eNB建立RRC连接；
2)macro eNB跟LCC建立此UE的控制面连接；
3)UE跟核心网进行鉴权和认证；4)LCC为UE创建上下文；
5)UE上报测量报告，其中包括当前和相邻LTE小区的无线信号质量测量结果，以及周围5G小区的无线信号质量测量结果；
6)UE发起实时在线视频的业务，向网络发送业务承载资源修改请求；
7)LCC本地控制中心根据用户业务承载QoS及保障比特速率(Guaranteed Bit Rate,GBR)等参数，发现该业务的保障比特速率超过网络预先设定的对应于5G系统的阈值，因此决定5G网络最适合传输此类业务，检查UE上报的测量结果，有一个5G小区信号质量满足阈值，选择5G小区为该业务提供数据传输；
8)LCC通过UE当前LTE系统的控制面连接指示UE接入到指定的5G小区，这条信令消息包含LCC指定的5G小区的系统信息，如物理信道配置，随机接入配置信息等；

12)LCC分别向5G接入节点和LDC触发信令消息，为UE建立5G专用数据承载；
13)5G接入节点通过5G RRC连接指示UE建立无线数据承载；
14)UE通过5G接入节点和LDC建立的数据承载传输实时视频业务数据。
实施例3：前述实施例1、2中，是在RAT1不存在控制面连接情况下的实施，但若RAT1存在控制面连接时，终端设备可以通过RAT1的控制面连接指示建立RAT2的控制面连接，例如，UE首先经5G node跟网络建立一条控制面连接，然后经LTE macro eNB跟网络建立另一条控制面连接。
本实施例跟实施例1流程相似，区别在于UE先经5G node跟网络建立第一条控制面连接，在用户发起业务后，LCC决定由LTE网络传输业务，然后UE依据网络的指示通过LTE macro小区跟LCC以及CN建立第二条控制面连接，网络为UE建立经过LTE macro eNB到LDC的专用数据承载，在此承载上传输业务数据。
实施例4：本例将说明UE发起两个业务，分别通过两个RAT的数据路径传输的实施。
实施中，在网络侧设备上，若存在第一控制面连接与第二控制面连接时，可以通过所述终端设备与第二无线接入网络的第二接入节点建立的控制面连接，为向所述终端设备提供的业务建立数据承载。其中，第一控制面连接是通过第一无线接入网络的第一接入节点建立的，第二控制面连接是通过第二无线接入网络的第二接入节点建立的。
在终端设备上，在接收网络侧设备通过控制面连接发送的建立数据承载的指示时，则通过第二控制面连接接收指示。
并且，实施中，根据业务的承载参数在各无线接入网络中确定与向所述终端设备提供的业务相适应的无线接入网络，可以是根据以下参数之一或者其组合确定的：测量报告、业务的数据承载的QoS参数、所述终端设备所属用户预设的接入策略、各无线接入网络的无线资源负荷状况。本例中，终端设备所属用户预设的接入策略亦即用户喜好。
图7为双业务时多控制连接实施网络环境示意图，如图所示，结合实施例1、2，在该网络环境下，实施流程可以如下：
1)在实施例2的数据路径1传输实时在线视频业务的基础上，UE又发起了基于IP的语音传输(Voice over IP，VOIP)业务；2)LCC根据该业务的QoS参数，QoS等级指示(QoS Class Indicator，QCI)值为1，检查用户喜好(可以是签约信息的一部分)，对于QCI为1的业务，用户希望由LTE系统传输，因此LCC决定由LTE网络提供业务传输；3)LCC与LTE macro eNB以及LDC进行信令交互，为此UE建立一条新的数据承载或者修改已有的数据承载，并设置传输路径2；4)当LTE系统中的承载新建或修改完成后，UE通过该承载对应的数据路径2传输VOIP业务。
LCC针对每一个业务，根据每一个业务的承载参数在各无线接入网络中确定与为终端设备提供的每一个业务相适应的无线接入网络；针对每一个无线接入网络，通过终端设备与该无线接入网络的接入节点建立的控制面连接，为向所述终端设备提供的业务建立数据承载，并通过该数据承载向终端设备提供业务。
实施例5：本例将说明随着UE移动，5G控制面连接切换到另一个5G接入节点的实施。
图8为终端设备发生切换时多控制连接实施网络环境示意图，如图所示，结合实施例1，在该网络环境下，实施流程如下：
1)随着UE移动，移出5G接入节点1范围，进入5G接入节点2覆盖区域；
2)基于UE的测量报告，网络将5G控制面连接及数据路径切换到接入节点2，于此同时，LTE控制面连接保持不变。也即，在保持了RAT2的控制面连接，也保持了RAT1的控制面连接时，可以在RAT1、RAT2中确定与向终端设备提供的业务相适应的无线接入网络，并且，继续保持两个控制面连接。
实施例6：本例将说明随着UE移动，5G控制面连接被去激活，以及被重新激活的实施，也即，实施中可以进一步包括：根据各业务的承载参数在各无线接入网络中确定与为所述终端设备提供的各业务不相适应的无线接入网络；若存在通过该不相适应的无线接入 网络的接入节点建立的与终端设备的控制面连接，将该控制面连接和/或数据承载标识为不可用。
具体的，可以根据各无线接入网络的负荷，和/或运营商的策略，将各无线接入网络的接入节点建立的与终端设备的控制面连接和/或数据承载标识为不可用或可用。
图9为激活与去激活时多控制连接实施网络环境示意图，如图所示，结合实施例1、2、5，在该网络环境下，实施流程可以如下：
基于实施例1、2，随着UE移出5G覆盖范围，UE上报的测量结果显示5G系统的信号变差，而LTE信号保持较好的质量，则LCC将5G控制面连接及数据承载去激活，实施中的去激活是指控制面连接和/或数据承载相应的上下文信息仍然保留，但标志为不可使用。
随后，LCC指示LTE macro eNB为UE建立业务的数据承载，然后通知LDC将数据传输路径切转到LTE macro eNB。之后，当UE又移动到5G覆盖范围内，UE上报的测量结果显示5G系统的信号变好，LCC重新激活原来的5G控制面连接及数据承载，例中的激活是指原有的控制面连接/数据承载上下文信息不变，重新被标志为可使用，然后通知LDC将数据传输路径切转到5G接入节点。
实施例7：本例将说明在5G控制连接保持的同时，LTE macro eNB和LTE微基站(LTE pico eNB)为UE提供双连接的实施。
图10为LTE中双业务时的多控制连接实施网络环境示意图，如图所示，结合实施例1、2，在该网络环境下，实施流程如下：
1)在实施例2的数据路径1传输实时在线视频业务的基础上，UE又发起了文件传输协议(File Transfer Protocol，FTP)业务；2)LCC基于业务特点，判断由LTE网络提供业务传输，检查UE上报的测量报告，发现有LTE pico小区信号满足阈值；3)LCC与LDC信令交互，为此UE建立一条新的数据承载和路径；4)LCC指示macro eNB由pico eNB独自或者macro eNB和pico eNB共同为该业务建立数据承载；5)macro eNB收到指示，使用现有LTE双连接技术，跟pico eNB协调，为UE建立非分离或分离无线数据承载；6)UE通过建成的数据承载传输FTP业务数据。
实施例8：本例将说明在5G控制面连接保持的同时，LTE macro eNB和WiFi接入点(WiFi Access Point，WiFi AP)为UE提供数据承载聚合的实施。
图11为数据承载聚合时多控制连接实施网络环境示意图，如图所示，结合实施例1、2、7，在该网络环境下，实施流程如下：
实施例8跟实施例7的区别在于，在UE发起FTP业务后，LTE宏基站跟WiFi AP为 UE提供数据承载聚合，操作流程相同。
数据传输路径2从LDC到macro eNB，从macro eNB开始有两个分支，一个分支是通过LTE空口直接到UE，另一个分支是由macro eNB通过接入节点间接口到WiFi AP，再通过WiFi空口到UE。
