Description

一种传输数据流的无线承载处理方法及装置
本申请要求在2016年7月22日提交中国专利局、申请号为201610589413.7、发明名称为“一种传输数据流的无线承载处理方法及装置”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，特别涉及一种传输数据流的无线承载处理方法及装置。
背景技术
图1为现有长期演进(Llong Term Evolution，LTE)系统中承载模型示意图。如图所示，现有LTE中的承载涉及到多层映射，从EPS Bearer(EPS承载；EPS：Evolved Packet System，演进分组系统)与接入网E-RAB(E-UTRAN Radio Access Bearer，E-UTRAN无线接入承载，E-UTRAN：Evolution-Universal Terrestrial Radio Access Network，演进的全球地面无线接入网)之间一对一映射，接入网E-RAB和空口Radio Bearer(无线承载)之间也是一对一映射。
现有LTE系统中每个EPS bearer在空口只能与一个空口Radio Bearer映射，此外在S1-U接口会为每个EPS bearer建立一个单独的隧道，当一一映射时，无论配置还是数据包传输都比较简单，采取一对一的管道机制即可。但在5G系统中，核心网传输到无线接入网(Radio Access Network，RAN)侧的数据流，不再使用与RAN侧承载一一映射的方式，核心网下发的有可能是更细的数据流，因此RAN侧需要决定自己的承载映射方法，并完成配置过程，便于后续数据的正确传输和业务质量的保证。

具体实施方式
在现有系统中，核心网的EPS承载和接入网的无线承载之间是一一映射的关系，接入网根据S1消息中的承载配置信息来配置空口的无线承载。而在5G系统中，目前核心网希望使用更灵活的数据流管理机制，意味着核心网的数据不再满足与接入网承载之间一对一的简单映射关系。本发明实施例中将给出一种接入网在新的架构下进行无线承载建立和维护的方案，以适应核心网灵活的数据流机制，保障业务的服务质量，提升系统效率和用户体验。下面结合附图对本发明的具体实施方式进行说明。
在本发明实施例提供的技术方案中，核心网控制实体通过信令过程，将核心网的数据属性配置给接入网节点，接入网节点决定核心网数据到无线承载的映射，并进行无线承载的建立和维护过程，接入网节点进行上行和下行无线承载的管理和配置。
其中，核心网控制实体是指在5G系统中负责核心网相关控制功能的实体，例如，类似于LTE系统中的MME(Mobility Management Entity，移动性管理实体)。
接入网节点是指在5G系统中接入网侧负责控制功能的实体，可以是分布式的接入节点，例如，类似于LTE系统中的eNB节点，也可以是集中式的接入网集中控制节点。
在下行数据传输处理时，对于新出现的会话数据流，在数据发送之前，可以先进行信令过程，由核心网控制实体向接入网控制实体配置该数据流的QoS属性，继而接入网控制实体根据该QoS属性决定是否有合适的数据无线承载(Data Radio Bearer，DRB)，如果没有，则建立新的DRB，并通知接入网用户面实体(一般来说，接入网控制实体和用户面实体是统一的，例如都是eNB)将该数据流在该DRB上传输；
在上行数据传输处理时，UE(User Equipment，用户设备)先与核心网控制实体交互需要传输的上行数据流，由核心网控制实体决定其QoS属性，核心网控制实体需要将上行的QoS属性配置给接入网控制实体，也会配置给UE；继而接入网控制实体根据该QoS属性决定是否有合适的DRB，如果没有，则建立新的DRB，并通知UE将该数据流在该DRB上传输。上述DRB建立过程，是接入网节点和UE之间的过程。
实施中涉及到核心网的实体时，一般而言，核心网控制实体是管理核心网的控制面过程，所有信令相关的过程与它有关，核心网用户面实体是进行数据传输的节点，所以数据均从它进行传输。涉及到接入网节点时，一般情况下，接入网节点和接入网用户面节点是一个节点，例如都是eNB，从执行和逻辑角度来说，控制节点进行信令过程，用户面节点进行数据传输。为了更好的说明本发明实施例提供的技术方案，实施例中将对二者是一个节点以及二者分离的实施方式都进行说明。
在说明过程中，将分别从核心网控制实体侧与接入网节点侧、UE侧的实施进行说明，然后还将给出三者配合实施的实例以更好地理解本发明实施例中给出的方案的实施。这样的说明方式并不意味着三者必须配合实施、或者必须单独实施，实际上，当核心网控制实体侧与接入网节点侧、UE侧分开实施时，其也各自解决核心网控制实体侧与接入网节点侧、UE侧的问题，而三者结合使用时，会获得更好的技术效果。
在说明过程中，将分别说明UE至核心网的上行数据传输以及核心网至UE的下行数据传输，并将以实例进行具体实施说明。具体的，下行实施方式将会在下述的实施例1、2、3、4中进行说明，上行实施方式将会在下述的实施例5中进行说明。
图2为核心网控制实体侧的传输数据流的无线承载处理方法实施流程示意图，如图所示，可以包括：
步骤201、在核心网与UE之间有数据流需要传输时，核心网控制实体确定传输数据流所需的服务质量参数；
步骤202、核心网控制实体将所述服务质量参数传递至接入网节点。
图3为接入网节点侧的传输数据流的无线承载处理方法实施流程示意图，如图所示，可以包括：
步骤301、确定核心网控制实体传递至接入网节点的服务质量参数；
步骤302、根据所述服务质量参数对无线承载进行处理，用以传输核心网与UE间所需传输的数据流。
实施中，将所述服务质量参数传递至接入网节点，可以是通过承载建立消息将所述服务质量参数传递至接入网节点的；进一步的具体实施方式将会在下述的实施例1中进行说明。
或，将所述服务质量参数传递至接入网节点，是通过在向接入网节点发送的数据包中携带所述服务质量参数后传递至接入网节点的；进一步的具体实施方式将会在下述的实施例2中进行说明。
实施中，所述服务质量参数可以包括以下信息之一或者其组合：该数据流的服务质量 要求、该数据流的传输属性、特殊数据包的特征。
进一步的具体实施方式将会在下述的实施例1中进行说明。
实施中，在核心网与UE之间需要传输的数据流是上行数据流时，所述服务质量参数是根据UE通知所述核心网控制实体的上行数据流传输要求确定的。进一步的具体实施方式将会在下述的实施例5中进行说明。
图4为UE侧的传输数据流的无线承载处理方法实施流程示意图，如图所示，可以包括：
步骤401、在UE上根据接入网节点的要求对无线承载进行处理，所述接入网节点的要求是接入网节点根据核心网控制实体传递至接入网节点的服务质量参数进行要求的；
步骤402、通过所述无线承载传输核心网与UE间所需传输的数据流。
UE在传输下行数据时，实施方式可以参见接入网节点的实施描述，但实施中，在核心网与UE之间需要传输的数据流包含上行数据流时，还可以进一步包括：确定UE需要传输的上行数据流并通知核心网控制实体。
实施中，将所述传输要求通知核心网控制实体，是通过NAS信令通知的。
实施中，还可以进一步包括：接收通知，所述通知中包含了传输上行数据流的上行无线承载的各相关参数，以及上行数据流与上行无线承载之间的映射关系。
具体的涉及上行数据流传输的实施方式将会在实施例5中进行说明。
下面通过实例用以说明具体的实现方式。
首先对实施中涉及到的E-RAB的建立流程以及RRC(Radio Resource Control，无线资源控制)连接重配置过程进行简要说明，具体的可以参见其他技术文献。
图5是E-RAB的建立流程示意图，如图所示，MME在S1接口向eNB(演进基站)发起E-RAB的建立、修改和释放的过程，在E-RAB的建立和修改过程中，MME会告知eNB该RAB的速率参数和QoS(Quality of Service，服务质量)参数等，以便于eNB进行算法实现，来保证该承载的业务质量。
图6为使用RRC连接重配置过程示意图，如图所示，在接入网过程中，接入网配置承载一般是使用RRC连接重配置过程，配置专用无线承载。
实施例1：
本实施例以下行数据为例，说明无线承载的建立过程。
本例中，将服务质量参数传递至接入网节点，是通过承载建立消息将所述服务质量参数传递至接入网节点的。
具体实施中，当UE有下行数据需要传输，通常先由核心网用户面实体触发核心网控 制面实体，进行相关传输的建立过程，可以如下：
1、核心网控制面实体将服务质量参数传递至接入网节点，服务质量参数可以包括以下信息之一或者其组合：该数据流的服务质量要求、该数据流的传输属性、特殊数据包的特征。
具体的，核心网控制面实体在发现有新的下行数据流需要传输，而这个数据流的相关传输和配置并没有建立好，此时核心网控制面实体先向接入网节点发送承载建立消息，同时携带：
该数据流的服务质量要求：告知接入网节点该数据流的服务质量要求，包括QoS参数、业务优先级和速率参数等，QoS参数一般包括数据传输的时延特性和误块率，业务优先级包含业务优先级级别、是否可以抢占和被抢占属性，速率参数包含业务最大速率和保障比特速率等属性，还可以配置UE聚合速率；
该数据流的传输属性：告知接入网节点该数据流的一些传输属性，例如如果是IP数据包，可以以IP五元组的方式来给出该数据流的属性，如目标IP地址和端口号，原IP地址和端口号，和其他IP头部特点。以这些特点，接入网节点可以很容易的识别出哪些数据是属于这个数据流的，从而对这些数据流进行配置的业务质量保障；对于非IP数据流，也需要将这些数据流的显示属性配置给接入网节点，以便于识别该数据流。另外，也可以采取数据包中携带流标识的方式，来区分数据流，例如一个数据流是数据流1，另一个数据流是数据流2，数据流标识在数据包中携带，通过控制面的过程配置好数据流1的传输参数和服务质量，后续接收到携带该数据流标识的数据，就可以按照配置进行传输和处理。
特殊数据包的特征：还可以告知接入网节点，一些特殊数据包的特征，例如特殊数据包的包头或者包内容中携带哪些特殊的标识或者符号，用以标识特殊数据包，并可以对这些特殊数据包的服务等级做单独配置，例如提高优先级等，典型的应用是对于微信数据中的红包数据可以设置很高的优先级，以避免拥塞。
2、核心网控制面实体接收来自接入网节点的承载建立确认消息，则认为数据传输已经配置好，后续可以正常进行传输。
下面对对应的接入网节点的实施进行说明。
1、在通过信令面消息(例如承载建立消息)将所述服务质量参数传递至接入网节点时，根据所述服务质量参数对无线承载进行处理，可以包括：
在已有的接入网与UE之间的无线承载中搜寻满足所述服务质量参数要求的无线承载，在搜寻到满足所述服务质量参数要求的无线承载后，使用该无线承载传输核心网控制实体所需传输至UE的数据流；
或，在已有的接入网与UE之间的无线承载中搜寻满足所述服务质量参数要求的无线承载，在搜寻不到满足所述服务质量参数要求的无线承载后，根据接入网的资源确定是否能够建立满足所述服务质量参数要求的无线承载，若能建立则建立无线承载，并使用该无线承载传输核心网控制实体所需传输至UE的数据流。
具体的，接收来自核心网控制面实体的数据流建立信令，从中获取该数据流的服务质量要求，例如传输时延和误块率要求、业务优先级等，根据这些属性，先在已有的无线承载中搜寻，是否有满足相同传输条件的无线承载已经建立，如果没有则需要发起无线承载建立过程，并根据数据流的速率属性，对该数据流进行接纳，如果认为可以承载该数据流的传输，则认为接纳成功，如果资源不够，则接纳失败。
对于接纳的判断，根据接入网的资源确定是否能够建立满足所述服务质量参数要求的无线承载，可以是根据接入网的资源是否能够满足所述数据流所需的比特速率要求进行确定的。
具体的，接纳的过程，主要是判断接入网的无线资源是否能够保证该业务的速率要求。一般来说，保障比特速率是需要一定的资源预留来保障的，接入网节点可以根据保障比特速率要求和资源的占用情况，判断是否可以接纳该数据流。另外，即使是非保障比特速率要求，例如best effort(尽力而为)的业务，也是需要一定的基本速率要求的，可以以基本速率来判断是否能接纳该数据流。如果资源允许，则接纳成功，否则，则接纳失败。
对于接入网节点在判断新建的数据流是否已经有无线承载对应时，一般有如下方式：如果空口没有任何专用无线承载，则对于新建立的数据流，需要建立一个新的无线承载进行空口传输；如果空口已经有一些专用无线承载，则遍历所有的已有无线承载，比较已有的无线承载与新建数据流的服务质量是否相同，如果相同，可以考虑将数据流映射到已有的无线承载上，如果没有相同的，则需要建立新的无线承载。
判断服务质量是否相同的方式，一般来说，需要时延要求、误块要求、优先级等参数均相等，认为服务质量相同，例如最大传输时延要求都是300ms、误块率要求10-6、传输优先级相同，则认为服务质量要求相同，可以复用在一个无线承载。
另外，在一些实现中，也允许相近的服务质量映射到一个无线承载中，例如当时延要求都是300ms时，已有DRB误块率要求为10-6，而新建业务误块率要求为10-5，则也可以将新建数据流映射到该已有DRB中。或者时延相近，或者优先级相近，都可以考虑进行同类映射，具体取决于算法。
实施中，建立无线承载，可以包括：在与UE根据所述服务质量参数要求建立无线承载后，向核心网返回应答所述信令面消息的确认承载建立的消息，例如承载建立确认消息。
具体的，当接入网节点在其已有的无线承载中没有找到对应于该新建数据流的无线承载，并决定为其建立一个新的无线承载时，接入网节点发起空口无线承载建立过程，可以如下：
接入网节点向UE发送无线承载建立消息，携带无线承载的标识，例如承载ID，还需要携带与承载的数据流服务质量对应的传输配置，例如层2的传输模式AM/UM(Acknowledged Mode/Unacknowledged Mode，确认模式/非确认模式)、最大ARQ/HARQ(Automatic Repeat reQuest/Hybrid Automatic Repeat reQuest，自动重传请求/混合自动重传请求)传输次数、承载的对应的优先级等等。UE按照配置建立无线承载，之后向网络反馈完成信令。
2、接纳成功并且无线承载建立成功之后，接入网节点向核心网控制实体返回建立确认消息；后续根据配置进行数据传输。
实施中，若接入网节点与接入网用户面节点是分离的，还可以进一步包括：将建立的无线承载与所述数据流的对应关系通知接入网用户面节点。
具体的，如果接入网节点和接入网用户面节点是分离的，则接入网节点需要将DRB和数据流的对应关系通知给接入网用户面节点，例如满足什么特性的数据流需要映射到索引(index)为1的DRB上。
当传输相关的配置建立完成之后，对于后续的数据流，接入网用户面节点按照已经配置好的数据流和DRB的映射关系，对接收到的数据进行正确的映射，以确保相应的数据流可以匹配到对应的DRB进行传输，保证其传输质量。
实施中，在所述服务质量参数包括特殊数据包的特征时，还可以进一步包括：根据特殊数据包的特征和/或根据接入网节点上预设的数据包处理规则对所述数据流中的数据包进行识别；对识别出的数据包按对该数据包的要求进行处理。
具体的，对于数据流中的一些特殊的数据包，可以根据核心网配置的特殊包的识别方法，或者是接入网自己配置的识别方法，对数据包的包头部或者包内容部分进行解析，一旦发现是特殊的数据包，则可以进行特殊的处理，例如提升其传输优先级。典型的应用是可以对微信中的红包数据进行高优先级处理，以避免拥塞。提高优先级的处理，可以是将该特殊包直接映射到更高优先级的DRB上，且该DRB其余服务质量不低于原有DRB的服务质量，另一种方式是仍旧映射到原DRB上，但对该数据包进行高优先级处理，例如插入队列最前面，或者打一个特殊标签。
实施例2：
本实施例是基于包内信令的无线承载建立过程的，本例中，将服务质量参数传递至接 入网节点，是通过在向接入网节点发送的数据包中携带所述服务质量参数后传递至接入网节点的。
在本实施例中，核心网并不针对每个数据流进行控制平面的建立过程，而是采取一些预配置或者协商好的方式，以包内的信息来决定数据包的服务等级。举例说明，例如定义一些服务质量与包内域值的对应关系，以表格说明，包内的flow type(流类型)域取值为1，代表优先级为1，传输误块率10-6，传输时延要求100ms的业务；flow type取值为2，代表优先级为1，传输误块率10-6，传输时延要求300ms的业务，等等。甚至速率的信息也可以包含在该映射中。这个映射关系可以是标准规定好，或者采取一些公共信令的过程进行配置。
在实施中，在通过在向接入网节点发送的数据包中携带所述服务质量参数后传递至接入网节点时，根据所述服务质量参数对无线承载进行处理，可以包括：在已有的接入网与UE之间的无线承载中搜寻满足所述服务质量参数要求的无线承载，在搜寻到满足所述服务质量参数要求的无线承载后，使用该无线承载将核心网控制实体传输至的数据包传输至UE；或，在已有的接入网与UE之间的无线承载中搜寻满足所述服务质量参数要求的无线承载，在搜寻不到满足所述服务质量参数要求的无线承载后，建立满足所述服务质量参数要求的无线承载，并使用该无线承载将核心网控制实体传输至的数据包传输至UE。
具体的，当数据包到达时，接入网节点接收到该数据包，读取数据包中的相应的域，获得上述的flow type，并根据之前的配置或者约定，从flow type中获得服务质量信息，如果现有已经有无线承载用于该种质量的业务的传输，则将数据包直接发送到该无线承载上传输，如果没有对应的无线承载，则为其建立一个新的无线承载，并根据服务质量对该新的无线承载进行L1/L2的各种配置，建立完成之后，将数据包发送到该无线承载上传输。也即，建立无线承载，并使用该无线承载将核心网控制实体传输至的数据包传输至UE，可以包括：建立一个新的无线承载，并根据所述服务质量参数要求进行L1以及L2配置，配置完成后，使用该无线承载将核心网控制实体传输至的数据包传输至UE。
实施中，若接入网节点与接入网用户面节点是分离的，是将核心网控制实体传输至接入网用户面节点的数据包，在无线承载建立完成后，使用该无线承载将所述数据包传输至UE。
具体的，上述是假设接入网用户面节点和控制面节点合一，如果二者是分离的，则用户面节点接收数据包，如果没有对应承载，则通知控制面节点建立对应的无线承载。
实施中，还可以进一步包括：根据设置的定时器释放建立的无线承载。具体的，接入网可以设置相关的定时器，对于长期没有数据传输的无线承载，接入网可以进行无线承载 释放。
实施例3：
本实施例说明了无线承载修改过程。本例中，在已有的接入网与UE之间的无线承载中搜寻能够满足所述服务质量参数要求的无线承载，使用无线承载重配置流程对能够满足所述服务质量参数要求的无线承载中的某一无线承载进行重配置，在使之满足所述服务质量参数要求后，使用该无线承载传输核心网控制实体所需传输至UE的数据流。例如，在已有的接入网与UE之间的无线承载中搜寻满足所述服务质量参数要求的无线承载，若搜索不到满足所述服务质量参数要求的无线承载，则使用无线承载重配置流程对已有的无线承载中能够满足所述服务质量参数要求的无线承载中的某一无线承载进行重配置，在使之满足所述服务质量参数要求后，使用该无线承载传输核心网控制实体所需传输至UE的数据流。
具体的，对于核心网来说，新数据包到达，总是发起向接入网的建立过程。请求过程参见实施例1。
而对于接入网来说，在接收到核心网的建立请求之后，如果发现已经有相应的无线承载可以进行该数据流的传输，则此时并不需要进行无线承载的新建，而是根据需要对无线承载进行适当的修改，即可完成。修改可以包括：
当新数据流有速率要求时，此时需要将新的速率要求反映到该无线承载上，例如将新增加的速率与原有的速率进行加和，即得到合并的新速率，需要将该新速率要求配置给相关的无线承载。一般来说，速率的变化，仅需要接入网节点更新内部记录，以影响后续的调度等操作，无需通知UE；
如果新数据流的加入，造成原有的无线承载的配置参数有所改变，则需要将新的配置参数通知给UE；
需要将该数据流的属性与无线承载ID进行绑定，后续对于该属性的数据流在该无线承载上传输。
如果需要通知UE，则可以用例如RRC重配置消息对UE的无线承载进行重配置，在重配置完成之后，接入网节点向核心网控制节点返回该数据流传输建立完成。后续可以正常传输该数据流。
类似的，当核心网向接入网节点通知，有一个已有的数据流结束。接入网接收到该信令，查找该数据流对应的无线承载，并在该无线承载中去掉该数据流，例如无线承载对应的速率中减去该数据流得速率要求，在该无线承载所传数据的属性中去掉已结束数据流的属性，以及可能的其他配置更改。如果该数据流去掉之后，该对应无线承载中仍旧有数据， 则需要保留该无线承载，根据需要发起无线承载重配置。并在重配置完成之后，向核心网返回数据流结束确认消息。
类似的，当核心网向接入网节点通知，一个已有的数据流需要更新，例如服务质量发生变化。接入网接收到该信令，查找该数据流对应的无线承载，根据变化的信息，决定是否需要对该无线承载进行重配置，如果需要进行重配置过程，则在重配置完成之后，向核心网返回数据流更新完成。
实施例4：
本实施例说明了无线承载释放过程。本例中可以包括：根据设置的定时器释放建立的无线承载；和/或，在接到核心网控制实体通知数据流传输结束时，释放建立的无线承载。
具体的，当核心网向接入网节点通知，有一个已有的数据流结束。接入网接收到该信令，查找该数据流对应的无线承载，如果无线承载去掉该数据流之后，没有任何其他数据需要承载，则可以对该无线承载进行释放。则释放过程可以如下：
1、接入网节点通知UE，释放该无线承载；
2、接收UE返回的完成信令。
之后，接入网节点可以向核心网控制实体返回，数据流结束完成信令。
实施中，当该无线承载也是该UE的最后一个无线承载时，说明UE的数据都已经结束，此时可以直接释放该UE的RRC连接，过程与上述类似。
另外，除了核心网控制实体触发的释放，接入网控制实体还可以对无线承载设置定时器，超时之前，一直都没有任何数据在该数据承载上发送，则可以出发无线承载的释放。接入网节点需要通知UE释放承载，也需要通知核心网控制实体。
实施例5：
本实施例说明了上行无线承载管理过程。
一般来说，无线承载是双向的，即既有下行也有对应的上行。对于无线承载的下行方向，其参数配置和速率保障，数据流到无线承载的映射方式，是由接入网节点执行的。而对于无线承载的上行方向，其参数配置是由接入网节点决定，而由UE执行，速率保障既需要接入网节点的调度保障，也需要UE内部执行一定的优先级策略，数据流到无线承载的映射方式是由接入网节点配置的，但是映射这个动作是由UE执行的。
因此，对于上行无线承载来说，在建立时，接入网节点需要将相关的参数配置，上行无线承载的速率参数，上行无线承载的映射方式通知给UE。
如果是配合下行数据而建立的对应的上行承载，则是随着下行数据流的到达，更新和结束，来相应进行上行承载的建立和维护，具体过程同前实施例，区别在于前面实施例在 建立修改和释放下行无线承载时，需要对其上行无线承载也进行相应的操作。特别的，下行无线承载可能只需要配置传输参数，对于速率参数和数据流到无线承载的映射方式，不需要UE知道，可以不配置给UE，而对于上行无线承载来说，除了需要UE配合的传输参数，还需要配置速率参数和数据流到无线承载的映射方式。映射方式同前面下行的映射方式，包含对于特殊数据的处理。也即，实施中，在核心网与UE之间需要传输的数据流包含上行数据流时，还可以进一步包括：
建立或重配置传输上行数据的上行无线承载时，通过接入网节点通知UE该上行无线承载的各相关参数，以及上行数据流与上行无线承载之间的映射关系。
如果除了对应于下行数据的上行数据包之外，其它的由上行触发的新数据流，这类新数据流到达，通常过程如下：UE首先通过NAS非接入层过程，通知核心网有新数据到达，新数据的属性，然后由核心网来决定该数据的传输服务质量，并向接入网节点发起上行数据流对应的传输层建立过程。
核心网向接入网节点通知上行数据流的传输层建立和维护过程，与前述下行的流程类似。区别在于，对于上行无线承载，除了需要UE配合的传输参数，还需要配置速率参数和数据流到无线承载的映射方式。
当上行无线承载建立好之后，对应的上行数据由UE根据数据包的属性将其映射到对应的无线承载中去。例如对于数据包的包头中，相关的域及其组合满足已经配置的要求，则将其映射到规定的上行无线承载中去。也可以对数据包的内容部分有一定解析，对特殊包进行提升优先级等特殊处理。
实施中，可以使用RRC信令通过接入网节点通知UE。
具体的，接入网节点和UE之间的信令过程一般使用RRC信令过程。
