Description

业务数据分流方法、装置、基站和存储介质 技术领域
本申请涉及移动通信技术领域，例如涉及一种业务数据分流方法、装置、基站和存储介质。
背景技术
第5代移动通信系统(the 5th Generation mobile communication system，5G)已经在多个国家开始商用部署，并且第4代移动通信系统(4G)和5G融合组网的方式是一种主要的组网方式。在4G和5G融合组网中，用户终端(User Equipment，UE)可以同时连接上4G基站和5G基站，即演进的通用陆地无线接入网络新无线双连接(Evolved-Universal Terrestrial Radio Access Network-New Radio Dual Connectivity，E-UTRA-NR Dual Connectivity，EN-DC)UE，一般称为双连接UE。
双连接UE与移动网络(包括基站及核心网)之间的控制面的信令(如接入或切换等)的空口传输都经过主节点(Master Node，MN)(MN又称锚点，属于4G基站)，而用户面的业务数据的空口传输，既可以单独经过MN，也可以单独经过辅节点(Secondary Node，SN)(SN属于5G基站)，或者同时经过MN和SN。通常情况下，由于5G带宽更大、频谱效率和速率更高，双连接UE的业务数据单独经过5G基站即可，但是当出现5G基站负荷高，或者双连接UE业务量大，或者双连接UE的5G空口信道条件恶化等情况后，5G基站可能无法满足此双连接UE的业务需求，此时，可以考虑将一部分业务数据分流给4G基站进行传输。
在业务数据分流机制中，容易出现反复引起分流的乒乓问题。而解决乒乓问题的改进方法通常都需要4G基站的底层识别4G-UE(只支持4G而不支持双连接的UE以及支持双连接但当前只连接到4G的UE)和双连接UE，并进行差异化处理。该处理对作为4G基站基础核心且已经成熟商用的媒体接入控制(Medium Access Control，MAC)层算法框架冲击较大。同时，由于协议上的分流点是设置在高层的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层，跨层到底层进行联动分流处理，再考虑到实际网络中，支持双连接的UE会在4G-UE和双连接UE两种UE形态下动态转换，高层状态的变化还要通知到底层进行相应调整，更是增大了复杂性和处理开销。

具体实施方式
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本申请的说明，其本身没有特有的意义。因此，“模块”、“部件”或“单元”可以混合地使用。
下文中将结合附图对本申请的实施例进行说明。
5G已经开始商用部署，其中非独立组网(Non-standalone，NSA)比独立组网(Standalone，SA)部署更早更多。图1为本申请实施例提供的一种5G组网标准中的Option 3序列的示意图，图2为本申请实施例提供的一种5G组网标准中的Option 7序列的示意图，图3为本申请实施例提供的一种5G组网标准中的Option 4序列的示意图。NSA的代表有Option 3序列和Option 7序列，如图1和图2所示，其中Option 3x是通常采用的5G组网部署的方式。如果核心网从4G的演进的分组核心网(Evolved Packet Core，EPC)升级到5G的5G核心网(5GC)，那么相应的Option 3x就会演进成Option 7x。SA的代表有Option 4序列，如图3所示。其中，图1-图3中的长期演进(Long Term Evolution，LTE)是由第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)组织制定的通用移动通信系统(Universal Mobile Telecommunications System，UMTS)技术标准的长期演进，NR表示新无线。演进的LTE(evolved LTE，eLTE)表示无线通信解决方案组合。
上述三种组网方式均融合了4G和5G的组网方式，UE可以同时连接上4G基站和5G基站。在本申请实施例中，定义支持双连接并且建立了双连接的UE为双连接UE，只支持4G而不支持双连接的UE(主要是现网中已有的老4G用户终端)以及支持双连接但当前只连接到4G的UE定义为4G-UE，只支持5G而不支持双连接的UE以及支持双连接但当前只连接到5G的UE定义为5G-UE。4G-UE和5G-UE都是单连接UE。以NSA的Option 3x为例，支持此组网的UE必须先接入作为MN的4G基站，完成控制面的信令接入后，然后由MN控制此UE接入作为SN的5G基站，此时UE就与4G和5G基站建立了双连接。
双连接UE与移动网络之间的控制面的信令的空口传输都经过MN，而用户 面的业务数据的空口传输，既可以单独经过MN，也可以单独经过SN，或者同时经过MN和SN。5G标准协议在业务面定义了四种承载(bearer)类型：主小区组(Master Cell Group，MCG)bearer，辅小区组(Secondary Cell Group，SCG)bearer，MCG split bearer，SCG split bearer。MCG split bear和SCG split bearer都是指可以在MN和SN同时进行业务数据的分流传输，MCG split bear是MN负责将业务数据分流给SN，而SCG split bearer是SN负责将业务数据分流给MN。上述业务数据的分流操作是在基站的PDCP层功能实体完成的，由负责业务数据分流的分流端基站的PDCP层将数据分流到被分流的受流端基站的无线链路控制(Radio Link Control，RLC)层进行传输。在MCG split bear下，分流端是MN，受流端是SN。在SCG split bearer下，分流端是SN，受流端是MN。图4为本申请实施例提供的一种5G组网标准中Option 3和Option 3x的业务承载及业务数据分流的示意图，图5为本申请实施例提供的一种5G组网标准中Option 7和Option 7x以及Option 4的业务承载及业务数据分流的示意图。图5中的SDAP表示服务发现应用规范(Service Discovery Application Profile)。图4中的X2和图5中的Xn表示分流的业务数据。
示例性的，以Option 3序列为例，Option 3的分流承载类型是MCG split bearer，业务数据从作为MN的4G基站分流给作为SN的5G基站。通常部署的Option 3x的分流承载类型是SCG split bearer，业务数据从作为SN的5G基站分流给作为MN的4G基站，即在Option 3x下，分流端是5G基站，受流端是4G基站。由于业务数据分流机制的设计对系统性能会有较大影响，因此，在进行业务数据分流时，需要考虑4G基站下4G-UE的业务负荷、4G基站和核心网间的传输带宽、时延及抖动、双连接UE的4G空口信道质量等因素。如果4G基站下的4G-UE的业务负荷已经较高，4G-UE的用户感知开始受到影响，则不适合将双连接UE的业务数据分流至4G基站，以避免影响4G-UE的用户感知。如果4G基站和核心网间的传输带宽较小、时延及抖动较大、或者双连接UE的4G空口信道质量较差，而分流算法与4G/5G的时延、宽带匹配较差，分流的业务数据在两条链路的时延不一致导致传输控制协议(Transmission Control Protocol，TCP)乱序、缓冲和重排，触发TCP超时而收缩窗口，就会引起双连接UE业务性能恶化，用户体验速率反而比不分流更低，所以要慎重考虑是否进行双连接UE的业务数据分流。4G/5G业务分流，必须要能给双连接UE带来更好的感知体验，如业务的速率提升或时延下降等，同时考虑兼顾分流端的整体性能，否则就应该回退(如减少甚至关闭)业务分流。
以业界5G网络通常部署的Option 3x为例，4G/5G业务分流采用SCG Split bearer，即5G基站是分流端，4G基站是受流端，5G基站负责将业务数据分流给4G基站分流。在考虑4G基站下4G-UE负荷的方案中，设置了1个允许分流 的低负荷门限THR_Low和1个禁止分流的高负荷门限THR_High，且THR_High>THR_Low。当4G基站统计到自己的负荷Load(包含了4G-UE和双连接UE的总负荷)降到THR_Low以下时，4G基站允许双连接UE进行4G/5G业务分流。而当Load达到或超过THR_High后，则会停止已有的4G/5G业务分流，并且禁止新的4G/5G业务分流。上述业务数据分流机制原理简单，但是会引发乒乓问题。示例性的，4G基站允许双连接UE进行4G/5G分流后，会引起4G基站Load抬升，使得4G基站Load超过THR_High而退出分流。退出分流后，4G基站Load又会下降，可能低于THR_Low而又重新开始分流，如此反复引起分流的乒乓问题，虽然可采用抑制乒乓问题的定时器或计数器方式，但不能从根本上解决乒乓问题。
针对上述业务数据分流机制中存在的乒乓问题，一种改进方法是当4G基站的Load达到或超过THR_High后，4G基站的底层MAC层对双连接UE减少资源分配和降低调度优先级，以此来降低分流带来的负荷。这种方法涉及对4G基站的底层MAC层算法的调整，对4G基站底层技术冲击较大。
另一种改进方法是4G基站对4G-UE和双连接UE所占用的负荷分别进行实时统计和控制，如果发现当前Load达到或超过THR_High，且双连接UE所占用的负荷超过一个预设门限THR_High_EN-DC，例如THR_High_EN-DC为THR_High的50％，则减少和限制双连接UE占用的资源。但这种方法需要4G基站在底层MAC层实时进行两类UE负荷的区分统计和资源调度调整，需要对4G基站的底层MAC层算法进行调整，同样对4G基站底层技术冲击较大。
还有一种改进方法是4G基站根据双连接UE的4G状态，如空口信道的质量，实时估算占用使得Load不超过THR_High的剩余资源可以承载的业务数据量，以此确定和控制4G分流的业务数据量，但这种方式同样涉及到对4G基站底层MAC层算法的调整，复杂度较高，对4G基站底层技术冲击较大。
由此可见，上述3种改进方法都需要4G基站的底层识别4G-UE和双连接UE，并进行差异化处理，对作为4G基站基础核心且已经成熟商用的MAC层算法框架冲击较大，而协议上的分流点是设置在高层的PDCP层，跨层到底层去进行联动分流处理，再考虑到实际网络中，支持双连接的UE会在4G-UE和双连接UE两种UE形态下动态转换，高层状态的变化还要通知到底层进行相应调整，更是增大了复杂性和处理开销。
为了解决业务数据分流机制中的乒乓问题，同时改进对4G基站底层技术冲击较大的缺陷。本申请中，在基站的PDCP层对业务数据进行分流控制，根据分流调整信息阶段性调整分流的业务数据量，无需对基站底层技术进行改动，不仅能够实现业务数据的自适应分流，而且不会产生乒乓问题，简单而有效， 适用于所有4G/5G融合组网类型，简化了业务数据分流机制，并提高了业务数据分流机制的高效性和适用性。
在一个示例性实施方式中，图6为本申请实施例提供的一种业务数据分流方法的流程示意图。该方法适用于在不改动底层技术的前提下，对业务数据自适应分流的情况。该方法可以由本申请提供的业务数据分流装置执行，该业务数据分流装置可以由软件和/或硬件实现，并集成在基站中，该基站可以作为受流端，可选的，受流端可以是4G基站，本申请实施例并不对受流端的基站类型进行限定。
如图6所示，本申请实施例提供的业务数据分流方法，包括：
S110、获取业务数据的当前负荷信息；其中，所述当前负荷信息包括当前统计负荷和当前测量负荷中的至少之一。
业务数据可以是双连接UE与移动网络之间的用户面的业务数据。当前负荷信息可以是受流端按照分流控制周期统计的统计负荷和/或实时测量的负荷信息，可以包括但不限于当前统计负荷和当前测量负荷中的至少之一。其中，当前统计负荷可以是根据分流控制周期所统计的负荷。分流控制周期可以是分流端设置的用于进行分流处理的周期，该分流控制周期的周期数值可以根据实际需求设定，本申请实施例并不对分流控制周期的周期数值进行限定。当前测量负荷可以是受流端实时测量的负荷。
在本申请实施例中，可以由受流端来获取业务数据的当前负荷信息。可选的，受流端的数量可以是多个，每个受流端可以和一个或多个分流端建立分流关系。可选的，可以由受流端的MAC层统计或测量当前负荷信息，并上报至受流端的RLC层。
S120、根据所述当前负荷信息与负荷门限阈值之间的数值关系，以及所述当前负荷信息匹配的负荷关联周期确定分流调整信息。
分流调整信息可以是受流端生成并发送给分流端的，用于分流端对分流给该受流端的分流业务数据量进行阶段性调整的信息。负荷门限阈值可以是受流端针对当前负荷信息所设定的门限阈值。可选的，负荷门限阈值的数量可以是多个，如3个或以上，本申请实施例并不对负荷门限阈值的取值以及数量进行限定。负荷关联周期可以是与当前负荷信息相匹配的周期，如用于周期性统计负荷的分流控制周期，或针对超高负荷所设定的超高负荷持续周期等，本申请实施例同样不对负荷关联周期的内容进行限定。
当受流端的RLC层获取到MAC层上报的当前负荷信息后，可以根据当前 负荷信息与负荷门限阈值之间的数值关系，以及当前负荷信息匹配的负荷关联周期确定分流调整信息。例如，当当前统计负荷小于多个负荷门限阈值中一个负荷门限阈值时，确定上调分流的分流调整信息。当当前统计负荷或当前测量负荷大于多个负荷门限阈值中一个负荷门限阈值时，确定下调分流的分流调整信息。当当前统计负荷位于两个负荷门限阈值之间，或当前测量负荷小于多个负荷门限阈值中一个负荷门限阈值时，确定不作调整的分流调整信息。
S130、将所述分流调整信息发送至分流端，以使所述分流端根据所述分流调整信息阶段性调整受流端的分流业务数据量。
分流业务数据量可以是分流端分流给受流端的业务数据量。
当受流端确定了分流调整信息后，可以将分流调整信息发送至分流端。可选的，分流端的数量可以是多个，每个分流端可以和一个或多个受流端建立分流关系。分流端可以通过PDCP层接收每个受流端的分流调整信息，同时通过PDCP层根据该分流调整信息阶段性调整该分流调整信息对应的受流端的分流业务数据量。
本申请实施例所涉及到的阶段性调整可以是按照设定步长阶段性地进行上调、下调或不作调整，而不是允许分流或禁止分流等针对分流业务数据量进行的刚性控制操作。例如，当受流端统计的当前统计负荷超过高负荷门限阈值时，分流端将根据该受流端确定并发送的分流调整信息、按照设定步长逐步下调发送给该受流端的分流业务数据量；当受流端统计的当前统计负荷低于低负荷门限阈值时，分流端将根据该受流端确定并发送的分流调整信息、按照设定步长逐步上调发送给该受流端的分流业务数据量，从而避免因直接允许或禁止分流导致的乒乓问题。
本申请实施例的分流端可以仅通过PDCP层对发送给受流端的分流业务数据量进行调整，而无需联动底层，实现简单且高效。同时，在本申请实施例中，分流端可以根据分流调整信息阶段性调整发送给受流端的分流业务数据量，从而解决业务数据分流机制存在的乒乓问题，实现业务数据的自适应分流。另外，本申请实施例所提供的业务数据分流方法适用于所有4G/5G融合组网类型，如Option 3/Option 4/Option 7序列，提高了业务数据分流机制的适用性。
本申请实施例中，受流端获取业务数据的当前负荷信息，根据当前负荷信息与负荷门限阈值之间的数值关系、以及当前负荷信息匹配的负荷关联周期确定分流调整信息，并将分流调整信息发送至分流端，以使分流端根据分流调整信息阶段性调整受流端的分流业务数据量，解决业务数据分流时的乒乓问题，实现业务数据的自适应分流，从而简化业务数据分流操作，并提高业务数据分流的高效性和适用性。
在一个示例性实施方式中，图7为本申请实施例提供的另一种业务数据分流方法的流程示意图。本实施例以上述实施例为基础进行说明，在本实施例中，给出了获取业务数据的当前负荷信息以及根据所述当前负荷信息与负荷门限阈值之间的数值关系，以及所述当前负荷信息匹配的负荷关联周期确定分流调整信息的一种可选的实现方式。如图7所示，本实施例的方法可以包括：
S210、获取业务数据的当前负荷信息。
S210可以包括以下至少之一：
S211、根据分流控制周期获取业务数据的所述当前统计负荷。
S212、实时测量当前负荷，以获取所述当前测量负荷。
在本申请实施例中，为了实现对受流端的周期性分流控制，受流端可以根据分流控制周期获取业务数据的当前统计负荷，以根据当前统计负荷确定匹配的分流调整信息。可选地，为了实现对受流端超高负荷的实时监控，受流端还可以实时测量当前负荷，以获取当前测量负荷。从而受流端可以根据当前测量负荷确定匹配的分流调整信息。
图7仅是一种实现方式的示意图，步骤S211和步骤S212之间并没有先后顺序关系，可以先实施步骤S211，再实施步骤S212，也可以先实施步骤S212，再实施步骤S211，还可以两者并行实施。
S220、根据所述当前负荷信息与负荷门限阈值之间的数值关系，以及所述当前负荷信息匹配的负荷关联周期确定分流调整信息。
所述负荷门限阈值可以包括低负荷门限阈值及高负荷门限阈值；所述负荷关联周期可以包括分流控制周期。
低负荷门限阈值可以是用于限定上调分流业务数据量的门限阈值，高负荷门限阈值可以是用于限定下调分流业务数据量的门限阈值。示例性的，可以设置低负荷门限阈值取值为60％，高负荷门限阈值取值为80％，本申请实施例并不对低负荷门限阈值及高负荷门限阈值的取值进行限定。
S220可以包括：
S221、在分流控制周期时刻，判断当前统计负荷是否小于低负荷门限阈值，若当前统计负荷小于低负荷门限阈值，则执行S222，若当前统计负荷不小于低负荷门限阈值，执行S223。
S222、将上调分流调整信息作为所述分流调整信息。
S223、判断当前统计负荷是否大于高负荷门限阈值，若当前统计负荷大于 高负荷门限阈值，则执行S224，若当前统计负荷不大于高负荷门限阈值，执行S225。
S224、将下调分流调整信息作为所述分流调整信息。
S225、将拒绝分流调整信息作为所述分流调整信息，或，设置所述分流调整信息为空。
分流控制周期时刻可以是一个完整的分流控制周期对应的周期终止时间点。
在本申请实施例中，在分流控制周期时刻，在确定当前统计负荷大于或等于低负荷门限阈值，且小于或等于高负荷门限阈值的情况下，将拒绝分流调整信息作为分流调整信息，或，设置分流调整信息为空；在分流控制周期时刻，在确定当前统计负荷小于低负荷门限阈值的情况下，将上调分流调整信息作为分流调整信息；在分流控制周期时刻，在确定当前统计负荷大于高负荷门限阈值的情况下，将下调分流调整信息作为分流调整信息。
上调分流调整信息可以是阶段性上调分流业务数据量的信息，下调分流调整信息可以是阶段性下调分流业务数据量的信息，拒绝分流调整信息可以是保持当前分流业务数据量不变，也即不对当前分流业务数据量进行调整的信息。
在本申请实施例中，如果到达分流控制周期时刻，且当前统计负荷大于或等于低负荷门限阈值，且小于或等于高负荷门限阈值，则受流端可以生成拒绝分流调整信息发送给分流端，或直接不向分流端发送任何调整信息；如果当前统计负荷小于低负荷门限阈值，则受流端可以生成上调分流调整信息发送给分流端；如果当前统计负荷大于高负荷门限阈值，则受流端可以生成下调分流调整信息发送给分流端。
所述负荷门限阈值还可以包括超高负荷门限阈值；所述负荷关联周期还可以包括超高负荷持续周期。
超高负荷门限可以是用于限定下调分流业务数据量的门限阈值，其取值要大于高负荷门限阈值。超高负荷门限阈值主要用于判断是否存在突发超高负荷的情况。示例性的，可以设置超高负荷门限阈值取值为90％。
S220还可以包括：
S226、判断当前测量负荷是否大于或等于超高负荷门限阈值，若当前测量负荷大于或等于超高负荷门限阈值，则执行S228，若当前测量负荷小于超高负荷门限阈值，执行S227。
受流端还可以在分流控制周期内，实时判断测量负荷是否大于或等于超高负荷门限阈值。其中，分流控制周期内可以是分流控制周期对应的周期时间段。
S227、保持当前分流控制周期的分流调整信息。
S228、判断当前测量负荷大于或等于超高负荷门限阈值的持续时间是否达到超高负荷持续周期，若当前测量负荷大于或等于超高负荷门限阈值的持续时间达到超高负荷持续周期，则执行S224，若当前测量负荷大于或等于超高负荷门限阈值的持续时间未达到超高负荷持续周期，执行S227。
超高负荷持续周期可以用于判断超高负荷的持续时间是否超过一定范围。可选的，超高负荷持续周期的周期时间要小于分流控制周期的周期时间。
如果受流端在分流控制周期内检测到当前测量负荷大于或等于超高负荷门限阈值，且当前测量负荷大于或等于超高负荷门限阈值的持续时间达到超高负荷持续周期，表明网络中发生了突发超高负荷的情况，此时可能未到达分流控制周期的终止时间点。因此，针对突发超高负荷，需要立即生成下调分流调整信息并发送至分流端，以使分流端立即根据下调分流调整信息下调受流端的分流业务数据量，避免影响用户感知。如果受流端检测到当前测量负荷小于超高负荷门限阈值，或者，当前测量负荷大于或等于超高负荷门限阈值的持续时间没有达到超高负荷持续周期，则表明网络中没有发生突发超高负荷的情况，此时可以保持当前分流控制周期的分流调整信息。也即，不向分流端发送任何分流调整信息。
图7仅是一种实现方式的示意图，步骤S221-S225和步骤S226-S228之间并没有先后顺序关系，可以先实施步骤S221-S225，再实施步骤S226-S228，也可以先实施步骤S226-S228，再实施步骤S221-S225，还可以两者并行实施。
S230、将所述分流调整信息发送至分流端，以使所述分流端根据所述分流调整信息阶段性调整受流端的分流业务数据量。
在本申请的一个可选实施例中，所述将所述分流调整信息发送至至少一个分流端，可以包括：按照分流控制周期或超高负荷持续周期，将所述分流调整信息发送至所有与受流端建立分流关系的分流端，或，按照分流控制周期或超高负荷持续周期，将所述分流调整信息发送至在当前分流控制周期或上一个分流控制周期内与受流端建立分流关系的分流端。
如果受流端的网络中没有发生突发超高负荷的情况，则受流端可以按照固定的分流控制周期发送分流调整信息至分流端。一旦受流端的网络中发生突发超高负荷的情况，则受流端可以在确定突发超高负荷的持续时间到达超高负荷持续周期后，立即将下调分流调整信息发送至分流端。受流端可以将分流调整信息发送至所有与受流端建立分流关系的分流端，或者，受流端还可以将分流调整信息仅发送至在当前分流控制周期(超高负荷持续周期所在的分流控制周 期)或上一个分流控制周期内与受流端建立分流关系的分流端。
采用上述技术方案，受流端通过固定的分流控制周期确定分流调整信息，以使分流端对发送至受流端的分流业务数据量进行周期性的调整；并在受流端检测到突发超高负荷时，受流端立即向分流端发送下调分流调整信息，以使分流端立即针对突发超高负荷情况下调发送至受流端的分流业务数据量，实现了对受流端分流业务数据量的精细化调整，能够有效避免乒乓问题，实现了业务数据的自适应分流，简化了业务数据分流机制，并提高了业务数据分流机制的高效性和适用性。
在一个示例性实施方式中，图8为本申请实施例提供的另一种业务数据分流方法的流程示意图。该方法适用于在不改动底层技术的前提下，对业务数据自适应分流的情况。该方法可以由本申请提供的业务数据分流装置执行，该业务数据分流装置可以由软件和/或硬件实现，并集成在基站中，该基站可以作为分流端，可选的，分流端可以是4G基站或5G基站，本申请实施例并不对分流端的基站类型进行限定。
如图8所示，本申请实施例提供的业务数据分流方法，包括：
S310、接收受流端发送的分流调整信息；其中，所述分流调整信息由受流端根据业务数据的当前负荷信息与负荷门限阈值之间的数值关系，以及所述当前负荷信息匹配的负荷关联周期确定；所述当前负荷信息包括当前统计负荷和当前测量负荷中的至少之一。
S320、根据所述分流调整信息阶段性调整所述受流端的分流业务数据量。
在本申请实施例中，分流端可以通过PDCP层接收受流端发送的分流调整信息，同时通过PDCP层根据分流调整信息阶段性调整受流端的分流业务数据量。例如，当受流端的当前统计负荷超过高负荷门限阈值时，分流端会按照设定步长逐步下调发送给受流端的分流业务数据量。当受流端的当前统计负荷低于低负荷门限阈值时，分流端会按照设定步长逐步上调发送给受流端的分流业务数据量，从而避免因直接允许或禁止分流导致的乒乓问题。
本申请实施例的分流端可以仅通过PDCP层对发送给受流端的分流业务数据量进行调整，而无需联动底层技术，实现简单且高效。同时，在本申请实施例中，分流端可以根据分流调整信息阶段性调整受流端的分流业务数据量，从而解决业务数据分流机制存在的乒乓问题，实现业务数据的自适应分流。另外，本申请实施例所提供的业务数据分流方法适用于所有4G/5G融合组网类型，如Option 3/Option 4/Option 7序列，提高了业务数据分流机制的适用性。
本申请实施例通过受流端获取业务数据的当前负荷信息，以根据当前负荷信息与负荷门限阈值之间的数值关系，以及当前负荷信息匹配的负荷关联周期确定分流调整信息，并将分流调整信息发送至至少一个分流端。分流端接收到受流端发送的分流调整信息后，根据分流调整信息阶段性调整受流端的分流业务数据量，解决业务数据分流机制存在的乒乓问题，实现业务数据的自适应分流，从而简化业务数据分流机制，并提高业务数据分流机制的高效性和适用性。
在一个示例性实施方式中，图9为本申请实施例提供的另一种业务数据分流方法的流程示意图。本实施例以上述实施例为基础进行说明，在本实施例中，给出了接收受流端发送的分流调整信息以及根据所述分流调整信息调整所述受流端的分流业务数据量的一种可选的实现方式。同时给出了对多个分流终端的当前分流业务数据量进行调整的一种可选的实现方式。如图9所示，本实施例的方法可以包括：
S410、接收受流端发送的分流调整信息。
在本申请的一个可选实施例中，所述接收受流端发送的分流调整信息，可以包括：接收所述受流端按照分流控制周期发送的分流调整信息；或，接收所述受流端按照超高负荷持续周期发送的分流调整信息。
示例性的，在受流端不发生突发超高负荷的情况下，分流端可以接收受流端按照固定的分流控制周期发送的分流调整信息。如果受流端发生突发超高负荷的情况，则分流端可以接收受流端按照超高负荷持续周期立即发送的分流调整信息。
S420、根据所述分流调整信息阶段性调整所述受流端的分流业务数据量。
所述分流调整信息包括拒绝分流调整信息、空分流调整信息、上调分流调整信息或下调分流调整信息；S420可以包括：
S421、在所述分流控制周期时刻，根据所述拒绝分流调整信息或空分流调整信息，拒绝调整所述受流端的当前分流业务数据量。
S422、在所述分流控制周期时刻，根据所述上调分流调整信息，按照分流数据调整步长上调所述当前分流业务数据量。
S423、在所述分流控制周期时刻，根据所述下调分流调整信息，按照分流数据调整步长下调所述当前分流业务数据量。
当前分流业务数据量也即分流端当前时刻分配给受流端的业务数据量。分流数据调整步长可以用于阶段性调整受流端的分流业务数据量。示例性的，分 流数据调整步长可以取值为10Mbps等。分流数据调整步长可以是固定值，也可以根据实际需求设置为可变值，本申请实施例并不对分流数据调整步长的取值以及取值方式进行限定。
示例性的，在受流端没有发生突发超高负荷的情况下，如果分流端在分流控制周期时刻接收到拒绝分流调整信息或空分流调整信息，则可以不对受流端的当前分流业务数据量进行调整。如果分流端在分流控制周期时刻接收到上调分流调整信息，则可以按照分流数据调整步长上调受流端的当前分流业务数据量。如果分流端在分流控制周期时刻接收到下调分流调整信息，则可以按照分流数据调整步长下调受流端的当前分流业务数据量。
S424、在所述超高负荷持续周期时刻，根据所述下调分流调整信息，按照分流数据调整步长下调所述当前分流业务数据量。
示例性的，在受流端发生突发超高负荷的情况下，分流端接收到受流端实时发送的下调分流调整信息后，可以按照分流数据调整步长下调当前分流业务数据量。
图9仅是一种实现方式的示意图，步骤S420包括的多个子步骤之间并没有先后执行顺序。
S430、确定参与分流的每个分流终端的当前分流增益。
S440、根据每个分流终端的当前分流增益，对所述每个分流终端的当前分流业务数据量进行调整。
分流终端可以是参与分流的双连接UE。当前分流增益可以是分流终端的分流操作所带来的增益。在本申请的一个可选实施例中，所述当前分流增益可以包括：当前速率分流增益、当前时延分流增益或当前频谱效率分流增益。其中，当前速率分流增益可以是分流终端当前的速率增益，当前时延分流增益可以是分流终端当前的时延增益，当前频谱效率分流增益可以是分流终端当前的频谱效率增益。
在本申请实施例中，分流端还可以实时确定参与分流的每个分流终端的当前分流增益，以根据每个分流终端的当前分流增益，对每个分流终端的当前分流业务数据量进行调整，以获取更好的整体分流增益，从而提高业务数据的处理效率。
在本申请的一个可选实施例中，所述当前分流增益可以包括高分流正增益、低分流正增益、低分流负增益或零增益；所述根据每个分流终端的当前分流增益，对所述每个分流终端的当前分流业务数据量进行调整，可以包括：在保证分流业务数据量上限阈值的情况下，提高所述高分流正增益对应的分流终端的 当前分流业务数据量；降低所述低分流正增益对应的分流终端的当前分流业务数据量；停止所述低分流负增益对应的分流终端的当前分流业务数据量，并维持设定分流停止时长；将所述零增益对应的分流终端按照设定增益处理方式进行增益处理。
高分流正增益可以是增益比较高的正分流增益，低分流正增益可以是增益比较低的正分流增益，而低分流负增益则可以是增益值为负的增益。零增益对应的分流终端既可以是新加入的需要分流的终端，也可以是一直参与分流且未退出分流而增益值为零的分流终端。分流业务数据量上限阈值可以是在上一分流控制周期中，分流端对每个受流端调整的分流业务数据量的上限值。设定分流停止时长可以是根据实际需求设定的时长，本申请实施例并不对设定分流停止时长的取值进行限定。设定增益处理方式可以是对零增益对应的分流终端进行增益处理的方式，如设定零增益对应的分流终端按照平均增益、预测增益或高增益处理当前分流业务数据量。
在本申请实施例中，还可以对参与分流的每个分流终端的当前分流业务数据量进行调整，示例性的，分流端需要在保证分流业务数据量上限阈值的情况下，提高高分流正增益对应的分流终端的当前分流业务数据量，降低低分流正增益对应的分流终端的当前分流业务数据量，并停止低分流负增益对应的分流终端的当前分流业务数据量，并维持设定分流停止时长，将零增益对应的分流终端按照设定增益处理方式进行增益处理。也即，对于增益高的UE将分配更多的分流业务数据量，增益低的UE则分配更少的分流业务数据量，增益低于预置门限的或为低分流负增益的则停止分流，并停止一定时间。新进入的双连接UE可以按平均增益或预测增益或高增益分配分流业务数据量，并在兼顾公平和效率的原则下进行分配。
本申请实施例所提供的业务数据分流方法，将负责控制分流的基站定义为分流端，将接收分流的基站定义为受流端。网络里可以设置多个分流端和多个受流端，每个分流端都可以和一个或多个受流端建立分流关系，每个受流端也可以和一个或多个分流端建立分流关系。网络里可以接入多种类型的UE，部分UE双连接到一个分流端和一个受流端，该部分UE中又有部分双连接UE进行了业务分流。受流端可以设置分流控制周期，以周期性地进行分流处理。受流端还可以设置分流数据调整步长，需要调整的分流业务数据量可以按照分流数据调整步长进行阶段性调整，包括上调或下调；对于不需要调整的分流业务数据量则可以不进行调整。
受流端设置周期性下调分流的高负荷门限阈值和周期性上调分流的低负荷 门限阈值，以实现对分流业务数据的周期性和阶段性调整。另外，受流端还可以设置突发性禁止分流的超高负荷门限阈值，超高负荷门限阈值高于高负荷门限阈值，同时设置超高负荷门限阈值对应的超高负荷持续周期，超高负荷持续周期长度小于分流控制周期。例如，通过定时器的方式设置超高负荷持续周期。受流端需要实时获取自身的负荷，并按照分流控制周期进行统计。受流端如果发现当前测量负荷达到或超过超高负荷门限阈值，且持续时间达到了超高负荷持续周期，则立即向所有与受流端建立了分流关系的分流端或上个分流控制周期到当前时刻与受流端实际发生了分流关系的分流端发送下调分流调整信息。相关分流端接收到下调分流调整信息后，可以按照分流数据调整步长下调分流业务数据量。
同时，如果受流端按照分流控制周期统计的当前统计负荷，达到或高于高负荷门限阈值，则按照分流控制周期时间点向所有与受流端建立了分流关系的分流端或所统计分流控制周期内与受流端实际发生了分流关系的分流端发送下调分流调整信息。相关分流端接收到下调分流调整信息后，可以按照分流数据调整步长下调分流业务数据量；如果受流端按照分流控制周期统计的当前统计负荷，达到或低于低负荷门限阈值，则按照分流控制周期时间点向所有与受流端建立了分流关系的分流端或所统计分流控制周期内与受流端实际发生了分流关系的分流端发送上调分流调整信息。相关分流端接收到上调分流调整信息后，可以按照分流数据调整步长上调分流业务数据量；如果受流端按照分流控制周期统计的当前统计负荷，介于高负荷门限阈值和低负荷门限阈值之间，则受流端在分流控制周期时间点不发送分流调整信息，或者在分流控制周期时间点向所有与受流端建立了分流关系的分流端或所统计分流控制周期内与受流端实际发生了分流关系的分流端发送拒绝分流调整信息。相关分流端接收到拒绝分流调整信息后，可以不调整分流业务数据量。
分流端根据当前时刻收到一关联受流端发送的分流调整信息对分流到此受流端的业务数据量进行调整，作为后续待调整分流业务数据量上限阈值，此分流业务数据量上限阈值最小值为0，即如果当前分流业务数据量为0，则不再下调分流业务数据量。
另外，分流端还可以根据参与分流的双连接UE的当前分流增益进行分流调整。如果一双连接UE当前分流增益较低，如低于平均分流增益，则降低此UE的分流业务数据量比例。如果一双连接UE当前分流增益为负值，则停止其分流并维持设定分流停止时长。当设定分流停止时长结束后可以重新对该双连接EU进行分流，以提高业务数据的处理效率。如果当前分流增益是正增益，且增益值比较高，则可以提升其分流业务数据量的比例，但须保证总的分流业务数据量不能超过分流业务数据量上限阈值。
在一个示例性实施方式中，图10为本申请实施例提供的一种分流端、受流端和双链接UE组成网络的示意图。如图所示，网络中有2个分流端S1和S2，2个受流端R1和R2，分流端和受流端两两之间都建立有分流关系，有4个接入此网络并建立了双连接的UE1、UE2、UE3、UE4，它们分别双连接到不同的分流端和受流端的组合，这些双链接UE都可以进行业务数据分流。
图11为本申请实施例提供的一种分流端S和受流端R之间的分流方法示意图。如图11所示，分流端S的PDCP负责控制分流的业务数据量，与受流端R的RLC层进行分流业务数据的收发。受流端R统计自身负荷，并生成分流调整信息反馈给分流端S。分流端S根据受流端R的分流调整信息来确定下一周期时刻或当前时刻可分流给R的数据量，并结合当前与分流端S和受流端R有双连接关系的UE的业务需求及其他一些情况，如分流增益等，重新分配确定每个UE的分流业务数据量。
在一个示例性实施方式中，图12为本申请实施例提供的一种受流端的业务数据分流处理的流程图，如图12所示，受流端R可以实时统计自身负荷并与低负荷门限阈值、高负荷门限阈值以及超高负荷门限阈值进行比较，产生周期性分流调整信息或突发性分流调整信息，发送给所有分流端或当前时刻存在分流的分流端。图13为本申请实施例提供的一种分流端的业务数据分流处理的流程图。如图13所示，分流端S可以计算每个双连接UE的分流增益并接收受流端R的周期性分流调整信息或突发性分流调整信息。考虑新进入的双连接UE或双连接UE退出，以及业务变化等情况，分流端S需要根据当前UE的业务数据分流需求以及每个UE当前分流增益情况重新分配每个UE的分流数据量，在保证不超过分流业务数据量上限阈值的前提下，增益高的UE将分配更多的分流数据量，增益低的UE则分配更少的分流数据量，增益低于预置门限的UE则停止分流，新进入的双连接UE可以按平均增益或预测增益或高增益处理，并在兼顾公平和效率的原则下分配分流业务数据量。可选的，可以设置受流端R的周期性允许分流的低负荷门限阈值：LoadTHR_Low＝60％；受流端R的周期性禁止分流的的高负荷门限阈值：LoadTHR_High＝80％；受流端R的突发性禁止分流的超高负荷门限阈值：LoadTHR_SupHigh＝90％；受流端R的分流控制周期：Τ＝60秒；受流端R的超高负荷持续定时器(也即超高负荷持续周期)：Τ0＝10秒。根据受流端R的容量能力，结合上述高低负荷门限阈值和分流控制周期的设置以及分流数据调整步长和高低负荷门限阈值差值的关系，设定受流端R的分流数据调整步长为

在一个示例中，假设网络中具有1个分流端S和1个受流端R，1个双连接UE，并且无突发超高负荷。UE在时刻t已双连接在分流端S和受流端R上并进行了业务数据分流，受流端R在t时刻的当前统计负荷Load(t)＝70％，介于高负荷门限阈值LoadTHR_High＝80％和低负荷门限阈值LoadTHR_Low＝60％之间。故在t时刻，受流端R不向分流端S发送分流调整信息或发送不作调整的分流调整信息。在t+Τ时刻，由于受流端R下的单连接UE的业务增加，当前统计负荷Load(t+Τ)＝85％，超过高负荷门限阈值LoadTHR_High＝80％。故在t+Τ时刻，受流端R向分流端S发送下调分流调整信息。分流端S收到此信息后，将上个周期内的分流业务数据量按分流数据调整步长
Figure PCTCN2021093519-appb-000004
进行下调，作为下个周期内分流业务数据量上限阈值。在t+2·Τ时刻，由于受流端R下单连接UE的业务继续增加，分流下调所释放的资源被单连接UE增加的业务所占用，使得当前统计负荷Load(t+2·Τ)＝81％，仍然超过高负荷门限阈值LoadTHR_High＝80％。故在t+2·Τ时刻，受流端R继续向分流端S发送下调分流调整信息。分流端S收到此信息后，将分流业务数据量按分流数据调整步长
Figure PCTCN2021093519-appb-000005
再进行下调。在t+3·Τ时刻，当前统计负荷Load(t+3·Τ)＝70％，介于高负荷门限阈值LoadTHR_High＝80％和低负荷门限阈值LoadTHR_Low＝60％之间。故在t+3·Τ时刻，受流端R不向分流端S发送分流调整信息或发送不作调整的分流调整信息。在t+4·Τ时刻，由于受流端R下单连接UE的业务下降，使得当前统计负荷Load(t+4·Τ)＝50％，低于低负荷门限阈值LoadTHR_Low＝60％。故在t+4·Τ时刻，受流端R向分流端S发送上调分流调整信息。分流端S收到此信息后，将分流的数据量按分流数据调整步长
Figure PCTCN2021093519-appb-000006
进行上调。在t+5·Τ时刻，当前统计负荷Load(t+5·Τ)＝70％，介于高负荷门限阈值LoadTHR_High＝80％和低负荷门限阈值LoadTHR_Low＝60％之间。故在t+5·Τ时刻，受流端R不向分流端S发送分流调整信息或发送不作调整的分流调整信息。
在一个示例中，假设网络中具有1个分流端S和1个受流端R，1个双连接UE，并且有突发超高负荷。UE在时刻t已双连接在分流端S和受流端R上进行了业务数据分流，受流端R在t时刻的当前统计负荷Load(t)＝70％，介于高负荷门限阈值LoadTHR_High＝80％和低负荷门限阈值LoadTHR_Low＝60％之间。故在t时刻，受流端R不向分流端S发送分流调整信息或发送不作调整的分流调整信息。在t+Τ时刻，由于受流端R下的单连接UE的业务增加，当前统计负荷Load(t+Τ)＝85％， 超过高负荷门限阈值LoadTHR_High＝80％。故在t+Τ时刻，受流端R向分流端S发送下调分流调整信息。分流端S收到此信息后，将上个周期内的分流业务数据量按分流数据调整步长
Figure PCTCN2021093519-appb-000007
进行下调，作为下个周期内分流业务数据量上限阈值。在t+Τ时刻到t+2·Τ时刻之间，由于受流端R下的单连接UE的业务继续快速增加，分流下调所释放的资源被单连接UE增加的业务所占用，可能由于单连接UE的业务增加很快，或者因为信道条件恶化，受流端R发现当前测量负荷

进行下调。在t+3·Τ时刻，当前统计负荷Load(t+3·Τ)＝70％，介于高负荷门限阈值LoadTHR_High＝80％和低负荷门限阈值LoadTHR_Low＝60％之间。故在t+3·Τ时刻，受流端R不向分流端S发送分流调整信息或发送不作调整的分流调整信息。在t+4·Τ时刻，由于受流端R下单连接UE的业务下降，使得当前统计负荷Load(t+4·Τ)＝50％，低于低负荷门限阈值LoadTHR_Low＝60％。故在t+4·Τ时刻，受流端R向分流端S发送上调分流调整信息。分流端S收到此信息后，将分流的业务数据量按分流数据调整步长
Figure PCTCN2021093519-appb-000011
进行上调。在t+5·Τ时刻，当前统计负荷Load(t+5·Τ)＝70％，介于高负荷门限LoadTHR_High＝80％和低负荷门限LoadTHR_Low＝60％之间。故在t+5·Τ时刻，受流端R不向分流端S发送分流调整信息或发送不作调整的分流调整信息。
在一个示例中，假设网络中具有1个分流端S和1个受流端R，3个双连接UE。UE1、UE2、UE3在时刻t都双连接在分流端S和受流端R上进行了业务分流，受流端R在t时刻的当前统计负荷Load(t)＝70％，介于高负荷门限阈值LoadTHR_High＝80％和低负荷门限阈值LoadTHR_Low＝60％之间。故在t时刻，受流端R不向分流端S发送分流调整信息或发送不作调整的分流调整信息。但分流端S在t时刻，已统计得到UE1的分流增益(假设为当前速率分流增益)为30％，UE2的分流增益为10％，而UE3的分流增益为-20％，即负增益。故从t时刻到t+Τ时刻之间，分流端S主动停止UE3的业务数据分流并维持设定分流停止时长Τ1，并将分流的业务数据量在UE1和UE2之间重新进行分配。由于UE1的分流增益比UE2高，所以UE1可分配的当前分流业务数据量和UE2可分配的当前分流业务数据量之比值，可在上个周期时刻的相应比值的基础上参照增益比值进行上调。例如，上个周期时刻UE1、UE2及UE3的当前分流业务数据量比值为 1:1:1，则当前周期时刻UE1和UE2的当前分流业务数据量比值可以设置为2:1。在t+Τ时刻，由于受流端R下的单连接UE的业务增加，当前统计负荷Load(t+Τ)＝85％，超过高负荷门限阈值LoadTHR_High＝80％。故在t+Τ时刻，受流端R向分流端S发送下调分流调整信息。分流端S收到此信息后，将上个周期内的分流业务数据量按分流数据调整步长
Figure PCTCN2021093519-appb-000012
进行下调，作为下个周期内分流业务数据量上限阈值。同时基于t+Τ时刻统计的UE进入或退出以及分流增益等情况对每个UE重新进行分流业务数据量的分配。其中UE1的分流增益变为10％，UE2的分流增益变为30％，而UE3已经退出双连接，并且有1个新的UE4进入，默认其分流增益为平均增益，即20％。分流端S基于这3个UE的分流增益重新分配t+Τ时刻到t+2·Τ时刻的分流数据量，增益高的UE分配的分流业务数据量更高，增益低的UE分配的分流业务数据量更低。
在一个示例中，假设网络中具有分流端S1和分流端S2，受流端R，2个双连接UE。UE1在时刻t双连接在分流端S1和受流端R上进行了业务数据分流，UE2在时刻t双连接在分流端S2和受流端R上进行了业务数据分流。受流端R在t时刻的当前统计负荷Load(t)＝85％，超过高负荷门限阈值LoadTHR_High＝80％。故在t时刻，受流端R同时向分流端S1和分流端S2发送下调分流调整信息。分流端S1和分流端S2收到此信息后，各自将上个周期内的分流业务数据量按分流数据调整步长

商用网络里业务负荷是动态变化的，并大部分具有比较稳定的业务模型。利用上述业务数据分流机制，当受流端的业务增加或信道条件恶化导致受流端负荷抬升达到高负荷门限时，需要减少双连接UE的业务分流，优先保障自身单连接UE的业务需求。如果自身单连接UE的负荷持续攀升，双连接UE分流减少所释放的资源就会被单连接UE及时补位占用，使得受流端负荷高居不下，分流业务数据量就会按着步长不断往下降，最多降至为0。如果单连接UE负荷逐步降低，当下降到低负荷门限阈值以下时，双连接UE分流的业务数据量就可以按步长逐步提升，让受流端的资源得到充分利用，这样分流就达到了比较稳定 的动态平衡，而不会出现乒乓现象。另外，分流端可以根据自身下每个双连接UE的分流增益情况，重新分配每个UE的分流业务数据量，可以让分流获得最大增益。
由此可见，本申请实施例所提供的业务数据分流方法限制在基站的PDCP层进行业务数据的分流控制，按合适的周期和步长调整分流数据量，不会产生乒乓现象，并且可以应对突发负荷进行及时调整。同时，基于用户终端的分流增益进行分流业务数据量调整，能够获得更好的整体分流增益。另外，本申请实施例所提供的业务数据分流方法也无需对基站底层技术进行改动，简单而有效，适用于所有4G/5G融合组网类型，如Option 3/Option 4/Option 7序列，即MCG split bear或SCG split bear，分流点所在基站类型可以是任意类型，如4G基站和/或5G基站。
