技术领域technical field

本申请涉及通信技术领域，尤其涉及一种资源传输保障方法、装置及***。The present application relates to the field of communication technologies, and in particular, to a resource transmission guarantee method, device, and system.

背景技术Background technique

在现有5G网络架构进行通信传输时，主要通过网络切片提供网络资源保障，使用户面网络设备能够根据配置的网络切片进行资源保障。其中，终端设备在使用网络切片进行通信传输之前，事先定义了协议数据单元(protocol data unit，PDU)会话(session)与网络切片的对应关系，从而在进行通信传输时，根据服务质量(quality of service，QoS)流(flow)所属的PDU session确定适用的网络切片。例如，如图1所示，PDU session1对应的网络切片是网络切片1，PDU session2对应的网络切片是网络切片2。即所述PDU session1中的只能按照所述网络切片1的属性进行通信传输，所述PDU session2中的QoS Flow只能按照所述网络切片2的属性进行通信传输。When the existing 5G network architecture performs communication transmission, network resource guarantee is mainly provided through network slicing, so that user plane network equipment can guarantee resources according to the configured network slice. Among them, before the terminal device uses the network slice for communication and transmission, the corresponding relationship between the protocol data unit (protocol data unit, PDU) session (session) and the network slice is defined in advance, so that during communication and transmission, according to the quality of service (quality of service, QoS) flow (flow) belongs to the PDU session to determine the applicable network slice. For example, as shown in Figure 1, the network slice corresponding to PDU session 1 is network slice 1, and the network slice corresponding to PDU session 2 is network slice 2. That is, in the PDU session1, only communication and transmission can be performed according to the attributes of the network slice 1, and the QoS Flow in the PDU session2 can only be communicated and transmitted according to the attributes of the network slice 2.

然而，在实际通信传输过程中，每个业务流期望得到的资源传输配置不一定与所在PDU session对应的网络切片的属性相符。However, in the actual communication transmission process, the expected resource transmission configuration of each service flow may not necessarily match the attributes of the network slice corresponding to the PDU session in which it is located.

但目前的资源传输保障方法无法根据QoS Flow灵活的进行资源传输配置，无法满足实际需求。However, the current resource transmission guarantee method cannot flexibly configure resource transmission according to QoS Flow, and cannot meet actual needs.

具体实施方式detailed description

在现有5G网络架构进行通信传输时，主要通过网络切片提供网络资源保障，使用户面网络设备能够根据配置的网络切片进行资源保障。When the existing 5G network architecture performs communication transmission, network resource guarantee is mainly provided through network slicing, so that user plane network equipment can guarantee resources according to the configured network slice.

其中，终端设备在使用网络切片进行通信传输之前，事先定义了协议数据单元(protocol data unit，PDU)会话(session)与网络切片的对应关系，从而在进行通信传输时，根据服务质量(quality of service，QoS)流(flow)所属的PDU session确定适用的网络切片。例如，如图1所示，PDU session1对应的网络切片是网络切片1，PDU session2对应的网络切片是网络切片2。即所述PDU session1中的只能按照所述网络切片1的属性进行通信传输，所述PDU session2中的QoS Flow只能按照所述网络切片2的属性进行通信传输。Among them, before the terminal device uses the network slice for communication and transmission, the corresponding relationship between the protocol data unit (protocol data unit, PDU) session (session) and the network slice is defined in advance, so that during communication and transmission, according to the quality of service (quality of service, QoS) flow (flow) belongs to the PDU session to determine the applicable network slice. For example, as shown in Figure 1, the network slice corresponding to PDU session 1 is network slice 1, and the network slice corresponding to PDU session 2 is network slice 2. That is, in the PDU session1, only communication and transmission can be performed according to the attributes of the network slice 1, and the QoS Flow in the PDU session2 can only be communicated and transmitted according to the attributes of the network slice 2.

因此，目前的资源传输保障方法无法根据QoS Flow灵活的进行资源传输配置，无法满足实际需求。Therefore, the current resource transmission guarantee method cannot flexibly configure resource transmission according to QoS Flow, and cannot meet actual needs.

综上，现有通过网络切片提供资源传输保障的方式是基于PDU会话粒度进行设置的，其中，一个PDU会话中可以包含一个或多个QoS流。To sum up, the existing method of providing resource transmission guarantee through network slicing is set based on PDU session granularity, wherein one PDU session may contain one or more QoS flows.

而基于PDU会话粒度提供不同的资源预留保障或传输通道隔离方式，无法满足实际需求。However, providing different resource reservation guarantees or transmission channel isolation methods based on PDU session granularity cannot meet actual needs.

为解决该问题，本申请实施例提供一种资源传输保障的方法、装置及***，用以提供一种基于QoS流粒度提供不同的资源预留保障或传输通道隔离方式。To solve this problem, the embodiments of the present application provide a method, device, and system for resource transmission guarantee, so as to provide different resource reservation guarantee or transmission channel isolation methods based on QoS flow granularity.

Each network slice is carried from the wireless access network. The network is logically isolated from the core network to adapt to various types of applications. A network slice can be divided into at least three parts: wireless network sub-slice, bearer network sub-slice and core network sub-slice. Among them, network slicing is based on the concept of logic, which is the reorganization of resources. The reorganization is to select the required virtual machines and physical resources for a specific communication service type according to SLA (Service Level Agreement).

It is a security mechanism of the network and is used to solve network delay and A technique for problems such as blocking.

QoS的保证对于容量有限的网络来说是十分重要的，特别是对于流多媒体应用，例如VoIP和IPTV等，因为这些应用常常需要固定的传输率，对延时也比较敏感。The guarantee of QoS is very important for networks with limited capacity, especially for streaming multimedia applications, such as VoIP and IPTV, because these applications often require a fixed transmission rate and are sensitive to delays.
