Description

调整服务质量的方法、装置和*** 技术领域
本发明涉及无线通信技术，特别涉及一种调整服务质量的方法、装置和***。
背景技术
在移动通信技术中，可以通过服务质量流(Quality of Service Flow，QoS Flow)为粒度对业务服务质量进行保障，以满足不同的业务需求，例如不同的业务需求需要满足不同的时延，丢包率或抖动等服务质量。在通信过程中，承载业务数据的QoS Flow对服务质量的需求可能发生变化。通过调整QoS Flow的服务质量，可以在合理分配网络资源的同时，满足变化的业务需求。
例如，在视频监控应用中，终端(例如：监控摄像头)可以与监控服务器之间建立PDU会话。为了保证监控视频传输的质量，网络侧设备，例如PCF，根据签约信息或者应用服务器的需求，可以为视频监控的QoS Flow设置保证比特速率(gurantee bitrate,GBR)，使网络为该视频监控的数据流分配GBR资源，保证数据流传输的服务质量。另外，为了减少数据传输量，监控摄像头可以内置视频处理算法，对监控视频的数据流执行初步处理，例如人脸识别。监控摄像头将捕捉到的有价值的视频数据流发送到视频监控服务器进行进一步处理。因此，在数据传输过程中，可能不是一直存在高价值的数据包，从而出现某段时间内监控摄像头没有数据传输。可能造成为数据流分配的GBR资源的浪费。此时，可以调整该数据流的服务质量。
然而频繁调整QoS Flow的服务质量会有频繁的信令交互，时延高，效率低。

AMF网元是一种用于接入和移动性管理的网元。该网元主要用于接入控制、移动性管理、附着与去附着、和SMF网元选择。该网元可以作为N1和N2信令连接的锚点为SMF提供N1/N2 SM消息的路由。
SMF网元是一种用于会话管理的网元。该网元主要用于提供会话管理的控制面功能，如会话创建、修改、释放。该网元可以为用户分配IP地址、选择和重定向UPF网元。
UPF网元是一种用于用户面处理的网元。该网元主要用于用户面的业务处理，例如数据包的路由转发、QoS映射和执行。该网元可以从DN接收用户数据，通过接入网设备传输给UE；该网元还可以通过接入网设备从UE接收用户数据，转发到DN。该网元中为UE提供服务的传输资源和调度功能由SMF网元管理控制。
PCF网元是一种用于策略控制的网元。该网元主要用于提供统一的策略框架以管理网络行为，提供策略规则给控制层网络功能，同时负责获取与策略决策相关的用户签约信息。
接入网设备是一种为终端设备提供无线通信功能的设备。接入网设备包括但不限于：演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、施主基站(donor evolved nodeB，DeNB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(base band unit，BBU)，无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等。还可以为5G，如新空口(new radio，NR)***中的下一代NB(generation，gNB)或传输点(如TRP或TP)，5G***中基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如BBU或分布式单元(distributed unit，DU)等。

AF网元是一种用于应用服务的功能设备。该功能设备主要用于与3GPP核心网交互来提供服务，例如影响数据路由决策，策略控制功能或者向网络侧提供第三方的一些服务。
终端设备，可以简称为终端，是具有无线收发功能的设备，在本申请实施例中可称为UE。终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。终端设备可以是手机、平板电脑、带无线收发功能的电脑、VR终端、AR终端、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、运输安全中的无线终端、智慧城市中的无线终端、智慧家庭中的无线终端等。
接入网设备通过用户面接口N3和UPF相连，用于传送UE的数据；接入网设备通过控制面接口N2和AMF建立控制面信令连接；AMF通过N1接口与UE建立信令连接；AMF通过N11接口与SMF相连，AMF作为N1和N2信令连接的锚点为SMF提供N1或N2接口SM消息的路由；UPF通过N4接口与SMF相连。
如图2所示，在5G网络中，UE可以通过接入网设备与核心网侧的UPF之间建立至少一个PDU会话(PDU session)。一个PDU会话至少包括一个QoS流。一个QoS流可以用QFI来标识，QFI在每个PDU会话中唯一。一个QoS流的传输单元是数据 包。相同QoS流上的数据包获得相同的QoS保障(如包时延，误包率，优先级等)，不同的QoS保障需要不同的QoS流来提供。
PCF可以根据UE的签约信息、应用服务器的需求等信息为QoS流确定QoS参数。QoS参数包括GBR，MBR、ARP等。配置有GBR的数据流是需要保证传输比特率的。例如当网络发生拥塞时，保证该GBR数据流的传输资源。在通信过程中，,接入网设备、或者UE、或者核心网侧设备可以触发PDU会话修改过程以修改PDU会话中的数据流的服务质量。图3示出了一种PDU会话的修改流程，该流程包括：
S101:SMF触发PDU会话修改以修改QoS流的QoS。
该步骤可以基于本地配置的策略或者可以基于接收到了来自接入网设备的触发信令。例如当接入网设备向SMF通知其释放了特定QoS流的资源，SMF则可以触发PDU会话修改。在该示例中，接入网设备通过AMF向SMF发送N2消息，该N2消息中包括QFI，用户位置信息与QOS QoS Flow被释放的指示信息。
S102：SMF与PCF进行SM策略修改过程。
SMF向PCF发送Npcf_SMPolicyControl_Update_request消息。
该消息中可以包括SMF更新的策略信息。
PCF向SMF发送Npcf_SMPolicyControl_Update_response消息，消息中包括PCF授权的更新的策略信息。

S103：SMF向接入网设备发送N2 Session Request消息。
该消息中包括N2 SM information，NAS消息等。其中，N2 SM information包括新的QoS参数。
接入网设备接收到新的QoS参数后，根据新的QoS参数为该PDU会话的QoS流进行QoS调整。
S104：接入网设备向UE发送AN-specific resource modifcation消息。
该消息中包括PDU session modification command/Ack.
S105：接入网设备向SMF发送N2 session response消息。
该消息中包括N2 SM information、UE位置等信息。
S106：SMF可能向UPF发送Nsmf_PDUSession_UpdateSMContext Request消息。
Nsmf_PDUSession_UpdateSMContext Request消息包括新的QoS参数。UPF可以根据该新的QoS参数对该PDU会话的QoS流进行QoS调整。
S107：UPF向SMF发送Nsmf_PDUSession_UpdateSMContext Response消息。
上述过程具体可以参考3GPP标准23.502 v16.2.0章节4.3.3.2的内容。
上述QoS的调整过程中网元之间交互信令量较多，涉及的网元设备较多。鉴于视频监控业务的特点，在视频监控数据传输与数据停止传输以及数据重新传输的过程中可能需要频繁调整QoS Flow的服务质量，从而导致上述过程的频繁执行，使得各网元间信令交互频繁，调整QoS的时延高，效率低下。鉴于此，本申请实施例提供一种调整服务质量的方法，用于提高QoS调整的效率。在本申请中，PDU会话是会话的一种， QoS流是数据流的一种。本申请实施例提供的方案不但可适用于QoS流的QoS调整，也可以适用于其他数据流的QoS调整。为了便于叙述，本申请中，对PDU会话的QoS调整是对PDU会话中QoS流的QoS调整的简称。
图4是本申请提出的一种调整服务质量方法的流程示意图。该方法能够用于为数据流调整QoS。例如将原特定QoS参数的数据流的传输资源释放，或者，将原特定QoS参数的数据流的QoS参数修改为不同的QoS参数。与图3所示方法不同的是，图4所示的方法通过网络中的网元或者设备自行进行本地QoS调整，不触发PDU会话修改流程，降低了信令开销，提高了数据处理和传输效率。该方法可应用于视频监控、视频传输等场景时，能够在视频传输时及时调整QoS、提高网络资源利用率的同时，降低这一过程所带来的时延，提高了QoS调整的效率。
如图4所示，该方法包括：
S201：UE向AMF发送PDU会话建立请求。
S202：AMF向SMF发送PDU会话创建会话上下文请求消息。
在S202中，AMF可选择SMF，并向选择的SMF发送该PDU会话创建会话上下文请求消息。
