Description

启用反向映射机制方法、终端设备和网络设备Enable reverse mapping mechanism method, terminal device and network device

技术领域technical field

本申请涉及通信领域，并且更具体地，涉及启用反向映射机制的方法、终端设备和网络设备。The present application relates to the field of communications, and more particularly, to a method, a terminal device and a network device for enabling a reverse mapping mechanism.

背景技术Background technique

第五代移动通信技术(5G，5th generation mobile networks或5th generation wireless systems、5th-Generation)网络中考虑对多种新业务的支持，可能导致向用户设备(UE，User Equipment)配置的服务质量(QoS，Quality of Service)规则构造复杂、更新频繁，为此5G网络中引入了反向映射QoS控制的可选机制。主要思想是在下行数据包头添加QoS流标识(QFI，QoS Flow Identity)及反向映射指示，UE根据收到的下行数据自行产生QoS规则，用于上行数据的传输，从而减少会话管理功能(SMF，Session Management Function)和UE的信令交互。Considering support for a variety of new services in the fifth generation mobile communication technology (5G, 5th generation mobile networks or 5th generation wireless systems, 5th-Generation) network may lead to the quality of service ( QoS (Quality of Service) rules are complex in structure and frequently updated. For this reason, an optional mechanism for reverse mapping QoS control is introduced into the 5G network. The main idea is to add a QoS flow identifier (QFI, QoS Flow Identity) and a reverse mapping indication to the downlink data packet header, and the UE generates QoS rules by itself according to the received downlink data for the transmission of uplink data, thereby reducing the session management function (SMF). , Session Management Function) and UE signaling interaction.

具有临近业务(Prose，Proximity-based Services)能力的UE可以通过PC5无线接口与具有Prose能力的另外一个UE直接通信。当一个UE既具有通过5G网络连接外部数据网络，还具有Prose能力时，这个UE可以充当中继UE(relay UE)，另外一个具有Prose能力的远程UE(remote UE)可以通过PC5接口与relay UE建立直接连接，并通过relay UE与5G网络建立的协议数据单元(PDU，Protocol Data Unit)会话与外部网络交互。多个remote UE可以通过同一个relay UE接入第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)网络，这会导致relay UE与3GPP网络交互频繁，例如对于每个remote UE的业务，SMF都要想relay UE发送相应的QoS规则，relay UE与3GPP网络之间信令拥塞的可能性大大增加。现有技术无法针对这种情况为UE启用反向映射机制。A UE with Proximity-based Services (Prose, Proximity-based Services) capability can communicate directly with another UE with Prose capability through the PC5 wireless interface. When a UE has both the connection to the external data network through the 5G network and the Prose capability, the UE can act as a relay UE (relay UE), and another remote UE with Prose capability (remote UE) can communicate with the relay UE through the PC5 interface Establish a direct connection and interact with the external network through the protocol data unit (PDU, Protocol Data Unit) session established by the relay UE and the 5G network. Multiple remote UEs can access the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) network through the same relay UE, which will lead to frequent interactions between the relay UE and the 3GPP network. If the relay UE sends the corresponding QoS rules, the possibility of signaling congestion between the relay UE and the 3GPP network is greatly increased. The existing technology cannot enable the reverse mapping mechanism for the UE for this situation.

图1A是本申请实施例的应用场景一的示意图。图1A示例性地示出了5G网络***架构。其中，UE通过Uu无线接口与接入网络(AN，Access Network)进行接入层连接，交互接入层消息及无线数据传输，UE通过N1口与移动性管理功能(AMF，Access and Mobility Management Function)进行非接入层(NAS，None Access Stratum)连接，交互NAS消息。AMF是核心网中的移动性管理功能，会话管理功能(SMF，Session Management Function)是核心网中的会话管理功能，AMF在对UE进行移动性管理之外，还负责将从会话管理相关消息在UE和SMF之间的转发。策略控制功能(PCF，Policy Control Function)是核心网中的策略管理功能，负责制定对UE的移动性管理、会话管理、计费等相关的策略。用户面功能(UPF，User Plane Function)是核心网中的用户面功能，通过N6接口与外部数据网络进行数据传输，通过N3接口与AN进行数据传输。FIG. 1A is a schematic diagram of an application scenario 1 of an embodiment of the present application. FIG. 1A exemplarily shows a 5G network system architecture. Among them, the UE connects with the access network (AN, Access Network) through the Uu wireless interface, exchanges access layer messages and wireless data transmission, and the UE communicates with the mobility management function (AMF, Access and Mobility Management Function through the N1 interface) ) to connect to a non-access stratum (NAS, None Access Stratum) and exchange NAS messages. AMF is the mobility management function in the core network, and the session management function (SMF, Session Management Function) is the session management function in the core network. In addition to the mobility management of the UE, the AMF is also responsible for sending messages from session management to Forwarding between UE and SMF. The Policy Control Function (PCF, Policy Control Function) is a policy management function in the core network, and is responsible for formulating policies related to the mobility management, session management, and charging of the UE. The User Plane Function (UPF, User Plane Function) is the user plane function in the core network. It transmits data to the external data network through the N6 interface, and transmits data to the AN through the N3 interface.

UE接入5G网络之后，位于核心网的SMF通过控制信令将QoS规则发送给UE，UE使用QoS规则对上行业务数据进行匹配，将上行业务数据映射到合适的QoS流进行QoS控制。5G网络中考虑对多种新业务的支持，可能导致向UE配置的QoS规则构造复杂、更新频繁，为此5G网络中引入了反向映射QoS控制的可选机制。反向映射机制的主要思想是在下行数据包头添加QFI及反向映射指示，UE根据收到的下行数据自行产生QoS规则，用于上行数据的传输，从而减少了SMF和UE的信令交互。After the UE accesses the 5G network, the SMF located in the core network sends the QoS rules to the UE through control signaling. The UE uses the QoS rules to match the uplink service data, and maps the uplink service data to the appropriate QoS flow for QoS control. Considering the support of a variety of new services in the 5G network, the QoS rules configured to the UE may be complicated in structure and frequently updated. For this reason, an optional mechanism for reverse mapping QoS control is introduced into the 5G network. The main idea of the reverse mapping mechanism is to add QFI and reverse mapping instructions to the downlink data packet header. The UE generates QoS rules according to the received downlink data for the transmission of uplink data, thereby reducing the signaling interaction between the SMF and the UE.

图1B是本申请实施例的应用场景二的示意图。如图1B所示，具有Prose能力的UE可以通过PC5无线接口与具有Prose能力的另外一个UE直接通信。当一个UE既具有通过5G网络连接外部数据网络，还具有Prose能力时，这个UE可以充当relay UE，另外一个具有Prose能力的remote UE可以通过PC5接口与relay UE建立直接连接，并通过Relay UE与5G网络建立的PDU会话与外部网络交互。图1C是本申请实施例的应用场景三的示意图，如图1B所示，remote UE通过relay UE，即ProSe 5G UE-to-Network Relay与5G网络建立PDU会话。FIG. 1B is a schematic diagram of an application scenario 2 of an embodiment of the present application. As shown in FIG. 1B , a Prose-capable UE can communicate directly with another Prose-capable UE through the PC5 wireless interface. When a UE has both the connection to the external data network through the 5G network and the Prose capability, the UE can act as a relay UE, and another remote UE with Prose capability can establish a direct connection with the relay UE through the PC5 interface, and communicate with the relay UE through the Relay UE. The PDU session established by the 5G network interacts with the external network. FIG. 1C is a schematic diagram of application scenario 3 of the embodiment of the present application. As shown in FIG. 1B , the remote UE establishes a PDU session with the 5G network through the relay UE, that is, the ProSe 5G UE-to-Network Relay.

现有图1B的技术方案中，多个remote UE可以通过同一个relay UE接入3GPP网络，这会导致relay UE与3GPP网络交互频繁，例如对于每个remote UE的业务，SMF都要想relay UE发送相应的QoS规则，relay UE与3GPP网络之间信令拥塞的可能性大大增加。In the existing technical solution of Figure 1B, multiple remote UEs can access the 3GPP network through the same relay UE, which will lead to frequent interaction between the relay UE and the 3GPP network. For example, for each remote UE service, the SMF needs to relay the UE. By sending the corresponding QoS rules, the possibility of signaling congestion between the relay UE and the 3GPP network is greatly increased.

上述应用场景是本申请实施例可能应用的场景示例，本申请实施例不局限于上述应用场景，且不局限于5G网络场景。上述相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。The above application scenarios are examples of scenarios to which the embodiments of the present application may be applied, and the embodiments of the present application are not limited to the above application scenarios, and are not limited to 5G network scenarios.
