Description

一种新型服务质量架构在双连接***的配置方法及装置
相关申请的交叉引用
本申请基于申请号为201710312757.8、申请日为2017年05月05同日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及通信领域，具体涉及一种新型服务质量架构在双连接***的配置方法及装置、存储介质。
背景技术
第五代(the fifth Generation，5G)通信***在下一代核心网(NextGen Core Network，NG-CN)、下一代接入网(NextGen Radio Access Network，NG-RAN)与用户设备(User Equipment，UE)之间采用了一种新型的服务质量(Quality of Service，QoS)架构，其中，所述NG-RAN中至少包括可提供演进型通用陆地无线(Evolved Universal Terrestrial Radio Access，E-UTRA)接入的演进型长期演进(Evolved Long Term Evolution，eLTE)基站(Node B，NB)、与可提供新型无线(New Radio，NR)接入的下一代基站(Generation Node B，gNB)。
如图1示出了新型QoS架构，在该新型QoS架构中，NG-CN为每一个UE至少建立一个协议数据单元会话(Protocol Data Unit Session，PDU会话)，且利用非接入层(Non-Access Stratum，NAS)的数据包过滤器，NG-CN与UE会将上下行数据包分配到对应的QoS流(QoS Flow，QF)上，每个QF具有其QoS配置文件(QoS profile)(如可靠性、时延、速率等)。 在每个PDU会话的建立过程中，NG RAN为每个UE至少建立一个数据无线承载(Data Radio Bearer，DRB)，且利用接入层(Access Stratum，AS)的映射，NG-RAN与UE会将上下行QF分配到对应的DRB上，每个DRB具有其各自的数据包转发方式。
NG-RAN会将属于不同PDU会话的数据包映射到不同的DRB上，因此，在每个PDU会话的建立过程中，NG-RAN会为当前所建立的PDU会话至少建立一个默认数据无线承载(default DRB)，而是否建立专用数据无线承载(dedicated DRB)由NG-RAN自行决定。在下行方面，NG-RAN基于与NG-CN间的用户面接口(NG User Plane，NG-U)上所传输数据包的QF标识(QF Identity，QF ID)和与所述QF ID对应的QoS profile决定QF与DRB间的映射关系。在上行方面，UE将在无线接口(Uu)上传输的上行数据包以QF ID加以标记并承载于对应的DRB上发送给NG-RAN。进一步的，NG-RAN至少有两种方法可以控制QF上行数据包与DRB间的映射，即反射映射(Reflective mapping)方法与显示控制(Explicit Configuration)方法；而如果一个上行数据包没有上述两种方法需要的相关信息，那么UE可以将所述上行数据包映射在其隶属的PDU会话的default DRB上进行发送。
如图2示出了一种被称为双连接(Dual Connectivity，DC)的***架构形式，在所述DC***中，对于具备多收发机(multiple Rx/Tx)的UE，NG-RAN中UE当前的服务基站(称为第一网元)可以为所述UE选择一个合适的(比如无线信道的质量满足一定的门限)基站并添加给所述UE(将被添加的基站称为第二网元)，以使得两个基站能够共同为UE提供无线资源以进行用户面的数据传输。在有线接口方面，第一网元与NG-CN间会为UE建立控制面接口(NG Control Plane，NG-C)、第二网元与NG-CN间至多为UE建立NG-U接口，第一网元与第二网元之间会以理想或非理想 的接口(称为Xn接口)进行连接；在无线接口方面，第一网元与第二网元可以提供相同或不同的无线接入技术(Radio Access Technology，RAT)，并相对独立的对UE进行调度。
如图3示出了DC***中可配置的四种用户面承载类型。对某一承载而言，图3a示出了完整的层2(Layer 2，L2)协议栈都位于同一基站时的两种承载类型，在这种用户面模式中，第一网元与第二网元会分别与NG-CN建立NG-U接口；图3b、图3c分别示出了L2协议栈分别位于两个基站时的两种承载类型，在这种用户面模式中，仅第一网元会与NG-CN建立NG-U接口、而第二网元仅会通过Xn接口的用户面(Xn-U)与第一网元进行数据包的传输。进一步的，所述L2协议栈包括用于对QF与DRB进行映射的新AS子层、分组数据汇聚协议子层(Packet Data Convergence Protocol，PDCP)、无线链路控制子层(Radio Link Control，RLC)与媒体接入控制子层(Medium Access Control，MAC)。其中，对于图3a对应的用户面模式，L2协议栈都位于第一网元的承载称为主小区组(Master Cell Group，MCG)承载、L2协议栈都位于第二网元的承载称为辅小区组(Secondary Cell Group，SCG)承载；对于图3b、图3c对应的用户面模式，承载配置有两套RLC子层与MAC子层、并相对独立的分别位于两个基站，其中，图3b中对第二网元上仅配置有RLC子层和MAC子层的承载称为MCG分离承载(MCG split bearer)，图3c中对第一网元上仅配置有RLC子层和MAC子层的承载称为SCG分离承载(SCG split bearer)。
针对新型QoS架构下如何在双连接架构中实现用户面承载的建立并进行数据传输的技术问题，目前尚未提出有效的解决方案。

实施1
第一网元在为UE提供通信服务的过程中，收到NG-CN指示的PDU会话建立请求消息；第一网元进行无线资源管理、并可决定将所述PDU会话分流到第二网元进行传输。
如图8所示，本实例的实现过程可以包括：

这里，所述第一控制面消息至少包括所述PDU会话的信息、以及所述PDU会话中QF的相关信息。其中，所述PDU会话的信息至少可以包括所述PDU会话的标识、最大聚合比特速率、NG-CN为所述PDU会话分配的传输层地址与隧道端口地址。所述QF的相关信息至少可以包括所述QF的标识、QoS profile。
步骤802，第一网元进行分流决策；
具体的，第一网元根据所述第一控制面消息中携带的信息与其他获取的信息(如测量上报结果、负荷信息等)进行无线资源管理，如果第一网元判断需要对所述PDU会话进行分流(即应用DC模式)，那么第一网元继续执行分流决策。
这里，所述分流决策至少可以包括分流粒度、分流对象、以及分流承载类型。
其中，所述分流粒度可以包括但不限于以下之一：
a)将所述PDU会话中全部QF完整分流到第二网元；
b)将所述PDU会话中部分QF分流到第二网元；
c)将所述PDU会话中全部或部分QF的部分数据包分流到第二网元。
其中，在分流粒度选择b或c时，分流对象是指所述PDU会话中分流的部分QF。在分流粒度选择a时，所述分流对象指所述PDU会话中的全部QF。
其中，所述分流承载类型可以包括：SCG承载、SCG分离承载、MCG分离承载等。实际应用中，当所述分流粒度选择a或b时，所述分流承载类型可以是SCG承载和/或SCG分离承载；当所述分流粒度选择c时，所述分流承载类型可以是MCG分离承载。
本实例中，分流粒度选择为a或b，相应的分流承载类型为SCG承载和/或SCG分离承载，分流对象为所述PDU会话中分流的部分QF或所述PDU会话中的全部QF。
步骤803，第一网元根据所述分流决策，通过Xn接口向第二网元发送第三控制面消息(如第二网元添加请求、第二网元修改请求等)，所述第三控制面消息的作用是请求第二网元对分流资源进行接纳。所述第三控制面消息可以发生在第二网元添加程序中(如对应第二网元添加请求消息)、或第二网元修改程序中(如对应第二网元修改请求消息)。
其中，所述第三控制面消息中携带分流资源信息，所述分流资源信息中至少包括分流对象信息、分流承载类型信息。本实例中，分流粒度选择为a或b，相应的分流承载类型为SCG承载和/或SCG分离承载，分流对象为所述PDU会话中分流的部分QF或所述PDU会话中的全部QF。此时，分流资源信息中分流对象信息包含分流给第二网元的全部或部分QF的QF ID及其QoS profile。分流承载类型信息包含指示当前分流承载为SCG承载和/或SCG分离承载的信息。
如果所述分流粒度选择a，那么所述分流资源信息中还可以包括步骤801中所述PDU会话的信息；如果所述分流粒度选择b，那么所述分流资源信息中还可以包括所述QF在NG-U接口上被分配的传输层地址与隧道端 口地址信息。在所述两种选择时，所述分流资源信息中还可以包含第一指示以及安全相关信息，其中，所述第一指示用于通知第二网元建立一个默认数据无线承载，所述安全相关信息可以包括：第一网元为第二网元侧的无线资源安全而派生的密钥等。需要注意的是，实际应用中，在分流粒度选择b时，第一网元侧是否建立一个默认数据无线承载是可选的，但第一网元和第二网元中至少一个网元侧建立一个默认数据无线承载。
如果所述分流承载类型选择SCG分离承载，那么所述分流资源信息中还可以包括第一网元为分流QF提供的无线资源流量信息，所述无线资源流量信息可以表示为第一网元为DC划分的流量比特数值或比例数值、或者是UE的总流量数值信息。
步骤804，第二网元执行接纳、映射与资源配置；
具体的，第二网元接收到所述第三控制面消息后，首先根据其中携带的分流资源信息进行是否接纳的判断。实际应用中，第二网元可以接纳所述分流资源信息中分流对象信息所指示的部分QF或全部QF。只要第二网元的无线资源情况可以满足至少一个QF的请求，第二网元即允许接纳，否则不允许。
对于判断结果为接纳的QF，第二网元进行无线资源配置并得出相应的SCG无线资源配置信息。其中，所述SCG无线资源配置信息至少包括所述QF与SCG承载和/或SCG分离承载间的映射关系信息、SCG承载和/或SCG分离承载在第二网元的L2与物理层的协议栈配置信息、第二网元为所述QF分配的NG-U数据传输隧道的传输层地址与端口地址信息。
如果所述第三控制面消息的分流资源信息中包含第一指示且所述第一指示表示第二网元需为所述PDU会话建立默认数据无线承载时，那么第二网元需在SCG无线资源配置信息中标识哪一个SCG承载或SCG分离承载为默认数据无线承载。也就是说，所述SCG无线资源配置信息中还可以包 含用于指示哪一个分流承载为所述默认数据无线承载的标识。
对于SCG分离承载，第二网元还需作出不超过所述第三控制面消息中指示的无线资源流量信息的流量划分，并将所述流量划分的结果包含在所述SCG无线资源配置信息中。需要说明的是，对于SCG承载，第二网元在无线接口上建立各SCG承载的时间是由第二网元自行决定的，如果在当前过程中不予以建立，那么所述SCG无线资源配置信息中可以不必包括SCG承载的无线协议栈配置信息。
步骤805，第二网元向第一网元回复针对第三控制面消息的响应消息(如第二网元添加请求确认消息、或第二网元修改请求确认消息)，所述响应消息中包括所述SCG无线资源配置信息。
可选的，所述响应消息中还可以包括第二网元拒绝的QF的标识。
步骤806，第一网元与UE之间执行RRC连接重配置程序；
根据响应消息携带的信息，对第二网元配置的SCG分离承载，第一网元根据被接纳的QF与所述SCG分离承载的映射关系、隶属于各个SCG分离承载的QF的QoS profile、以及第二网元指示的流量划分结果，对所述SCG分离承载进行第一网元侧的无线资源配置、得出相应的MCG无线资源配置信息。
第一网元还需为各个SCG分离承载分配在Xn接口上传输分流数据的隧道的端口地址。
其中，如果有第二网元未接纳的QF，第一网元需决定对所述QF的操作，所述操作包括但不限于将所述QF释放。
第一网元将MCG无线资源配置信息(如果有)和SCG无线资源配置信息组合并生成RRC控制面请求信令(如RRC Connection Reconfiguration)，通过与UE间的无线接口发送给UE；如果UE对所述 RRC控制面信令所指示的资源配置成功，那么UE回复相应的RRC控制面确认信令(如RRC Connection Reconfiguration Complete)。
步骤807，第一网元收到UE回复的RRC控制面确认信令后，向第二网元发送Xn接口消息(如第二网元重配置完成消息)，所述Xn接口消息用于向第二网元指示UE成功应用了SCG无线资源配置信息。
其中，所述Xn接口消息还可以包括第一网元为各个SCG分离承载分配在Xn接口上的隧道的端口地址信息。
可选的，所述隧道的地址信息也可以携带在一条新的Xn接口消息中，并在收到来自第二网元的所述响应消息后由第一网元发送给第二网元。
步骤808，第一网元向NG-CN发送针对所述第一控制面消息的响应消息(如PDU会话资源建立请求响应)，所述响应消息中至少包括NG-RAN为接纳的QF分配的NG-U数据传输的地址信息与端口信息、以及拒绝接受的QF的标识(如果有)。
步骤809，UE与第二网元之间进行上行数据包传输。
对所述PDU会话，如果UE有上行数据包需要传输、而所述上行数据包没有任何指示信息以表明其对应于哪个承载时，如果对所述PDU会话仅在第一网元和第二网元中一侧建立了默认数据无线承载，那么UE将所述上行数据包映射在所述默认数据无线承载上进行传输；如果对所述PDU会话在第一网元或第二网元中两侧均建立了默认数据无线承载，那么UE可以根据第一网元指示的无线资源配置信息(如所述上行数据包是否属于分流对象)将所述上行数据包映射在对应的默认数据无线承载上进行传输。
实例2
第一网元在为UE提供通信服务的过程中进行无线资源管理。第一网元决定协同第二网元配置以MCG分离承载为用户面承载模式的架构，为UE 提供DC通信服务。
如图9所示，本实例的实现过程可以包括：
步骤901，对处于RRC_Connected的UE，第一网元执行分流决策，并通过Xn接口向第二网元发送第一控制面消息，以请求第二网元为指示的MCG分离承载提供无线资源，所述第一控制面消息携带分流资源信息；
在NG-C接口方面，所述第一控制面消息可能发生在PDU会话的建立过程中(即类似于实例1中的步骤801与步骤802、只是分流承载的类型选择为了MCG分离承载)、也可能发生在PDU会话的修改过程中(如NG-CN为所述PDU会话新添加一个QF)，或者NG-C接口方面无变化；在Xn-C接口方面，所述第一控制面消息可能发生在第二网元添加程序中、也可能发生在第二网元修改程序中(比如在步骤901发生之前，第一网元与第二网元已协同为UE建立了至少一个MCG分离承载)。
其中，所述第一控制面消息携带的分流资源信息可以包括：分流对象信息、分流承载类型信息，其中，由于当前需要配置MCG分离承载因而分流承载类型信息包含指示为MCG分离承载的信息，分流对象信息可以包含所述MCG分离承载中QF的QF ID及其QoS Profile信息、以及第一网元为所述MCG分离承载划分的无线资源流量信息；除此之外，所述分流资源信息还包括：第一网元对当前需要配置的MCG分离承载在第一网元侧的无线协议栈配置信息、第一网元为所述MCG分离承载在Xn-U接口(如果支持上行分离)分配的隧道端口地址信息。
步骤902，第二网元执行接纳与资源配置；
根据所述第一控制面消息中携带的分流资源信息，第二网元首先根据第一网元请求的无线资源进行接纳判决。如果第二网元可以接受至少一个所述MCG分离承载的添加，那么第二网元判断接受所述第一控制面消息的请求；否则拒绝。
对于接纳判决的结果为接纳的MCG分离承载，第二网元进行无线资源配置并得出相应的MCG无线资源配置信息，所述MCG无线资源配置信息中至少包括所述MCG分离承载在第二网元侧的L2(即RLC子层与MAC子层)与物理层的协议栈配置信息、第二网元为在Xn-U接口为所述MCG分离承载分配的隧道端口地址信息。
步骤903、第二网元将所述MCG无线资源配置信息携带在针对所述第一控制面消息回复的响应消息中(如第二网元添加请求确认消息、或第二网元修改请求确认消息)并通过Xn接口回复给第一网元；可选的，所述响应消息中还可以包括第二网元拒绝的MCG分离承载的标识；
步骤904，第一网元与UE之间执行RRC连接重配置程序；
根据所述响应消息中携带的MCG无线资源配置信息，第一网元可进行必要的无线资源配置，所述无线资源配置包括对被接受的MCG分离承载在第一网元侧的无线协议栈配置调整并得出相应的MCG无线资源配置信息、和/或对第二网元拒绝的MCG分离承载的操作。其中，所述操作包括但不限于将所述MCG分离承载配置为MCG承载并得出相应的MCG无线资源配置信息、或释放所述MCG分离承载(此时将所述MCG分离承载中的QF标识指示给NG-CN)。
本步骤中，第一网元可以将当前的MCG无线资源配置信息和之前获取的来自第二网元的SCG无线资源配置信息进行组合，生成RRC控制面请求信令并通过无线接口发送给UE；如果UE对所述RRC控制面请求信令所指示的资源配置成功，那么UE回复相应的RRC控制面确认信令给第一网元。
步骤905，第一网元接收到UE回复的RRC控制面确认信令后，第一网元向第二网元发送Xn接口消息(如，第二网元重配置完成消息)，所述Xn接口消息用于向第二网元指示UE成功应用了SCG无线资源配置信息。
在本实例中，默认数据无线承载仅会建立在第一网元侧，所述默认数据无线承载可以是MCG承载或MCG分离承载。因此，如果UE侧有上行数据包需要传输、而所述上行数据包没有任何指示信息以表明其对应于哪个承载，那么UE将所述上行数据包映射在建立于UE与第一网元间的无线接口上的默认数据无线承载上进行传输。
实例3
在DC***中，第一网元进行主要的无线资源管理，所述无线资源管理包括DC***中使用的用户面承载类型。比如，第一网元可决定改变某个承载的类型。
如图10所示，本实例的实现过程可以包括如下步骤：
步骤1001，第一网元执行分流决策，做出用户面承载类型改变的决定；
PDU会话建立(参考实例1的阐述)后，DC***中可能存在部分QF映射在一个MCG承载上、另一部分QF映射在一个SCG承载上的用户面模式。根据网络中不断变化的无线资源情况和/或第二网元的请求，第一网元可能做出用户面承载类型改变的决定，所述决定可以包括但不限于：将MCG承载改为SCG承载(或反之)、或将MCG承载改为SCG分离承载(或反之)、或将SCG承载改为SCG分离承载(或反之)。
其中，所述承载类型的改变会进一步的涉及到具体针对的QF。比如，将MCG承载改为SCG承载时，会涉及到：将所述MCG承载中的全部QF都分流到第二网元并映射到至少一个SCG承载上、还是仅将所述MCG承载中的部分QF分流到第二网元并映射到至少一个SCG承载上(而另一部分QF仍保留在所述MCG承载中)。也就是说，第一网元所做出的用户面承载类型改变决定需要包括具体的分流对象。
步骤1002，根据所述无线资源管理决策得出的用户面承载类型改变决 定，第一网元通过Xn接口向第二网元发送第二控制面消息，所述第二控制面消息可以是第二网元修改请求消息，用于请求第二网元接纳分流资源信息所指示的分流资源。
其中，所述第二控制面消息至少可以包括所述分流资源信息，所述分流资源信息中至少可以包括所述分流对象的信息(如QF ID及其QoS profile)、以及承载类型信息(如SCG bearer type)。
可选的，所述分流资源信息中还可以包括所述分流对象在第一网元侧与MCG承载的映射关系、以及MCG承载在第一网元侧的无线资源配置信息，这一部分内容可作为第二网元进行无线资源映射与配置的参考。
