Please refer to FIG. 1 , which shows a schematic diagram of a 5G network system architecture provided by an embodiment of the present application. As shown in FIG. 1 , the system architecture 100 may be composed of UE, (R)AN, Core (core network) and DN (Data Network, data network). Among them, UE, (R)AN, and Core are the main components constituting the system architecture 100. Logically, they can be divided into user plane and control plane. The control plane is responsible for the management of the mobile network, and the user plane is responsible for the transmission of service data.

UE: It is the portal for mobile users to interact with the network. It can provide basic computing capabilities and storage capabilities, display service windows to users, and accept user operation input. The UE can use the next-generation air interface technology to establish a signal connection and a data connection with the (R)AN, thereby transmitting control signals and service data to the mobile network.

(R)AN: Similar to the base station in the traditional network, it is deployed close to the UE, provides the network access function for authorized users in a specific area, and can use different quality transmission tunnels to transmit user data according to the user's level, service requirements, etc. . The RAN can manage its own resources, utilize them rationally, provide access services for the UE on demand, and forward control signals and user data between the UE and the core network.

DN: It is a data network that provides business services for users. Generally, the client is located in the UE, and the server is located in the data network. The data network can be a private network, such as a local area network, or an external network that is not controlled by operators, such as the Internet (Internet), or a private network jointly deployed by operators, such as in order to configure IMS (IP Multimedia Core Network Subsystem). , IP Multimedia Network Subsystem) services.

Fig. 2 is a schematic diagram of a detailed architecture determined on the basis of Fig. 1, wherein the core network user plane includes UPF (User Plane Function, user plane function); the core network control plane includes AUSF (Authentication Server Function, authentication server function) , AMF (Core Access and Mobility Management Function, core network access and mobility management function), SMF (Session Management Function, session management function), UDM (Unified Data Management, unified data management), PCF (Policy Control Function, policy Control function), AF (Application Function, application function).

AUSF: perform security authentication of the UE;

AMF: UE access management and mobility management;

SMF: UE session management;

UDM: user subscription context management;

PCF: User Policy Management;

In the system architecture shown in Figure 2, the Uu interface is the reference point between the UE and the (R)AN, and the UE establishes an access stratum connection with the (R)AN through the Uu interface, and exchanges access stratum messages and wireless data transmission; The N1 interface is the reference point between the UE and the AMF. The UE establishes a non-access stratum (None Access Stratum, NAS) connection with the AMF through the N1 interface, and exchanges NAS messages; the N2 interface is the reference point between the (R)AN and AMF. It is used for sending NAS messages, etc.; the N3 interface is the reference point between (R)AN and UPF, which is used to transmit user plane data, etc.; the N4 interface is the reference point between SMF and UPF, which is used to transmit, for example, N3 connected Information such as tunnel identification information, data buffer indication information, and downlink data notification messages; the N6 interface is the reference point between the UPF and the DN, and is used to transmit data on the user plane.

It should be noted that the name of the interface between each network element in FIG. 1 and FIG. 2 is just an example, and the name of the interface in the specific implementation may be other names, which are not specifically limited in this embodiment of the present application. The names of each network element (for example, SMF, AF, UPF, etc.) included in FIG. 1 and FIG. 2 are only an example, and the functions of the network elements themselves are not limited. In 5G and other future networks, the above-mentioned network elements may also have other names, which are not specifically limited in this embodiment of the present application. For example, in a 6G network, some or all of the above-mentioned network elements may use the terminology in 5G, and may also use other names, etc., which will be uniformly described here, and will not be repeated below. In addition, it should be understood that the names of the messages (or signaling) transmitted between the above network elements are only an example, and do not constitute any limitation on the functions of the messages themselves.

In an example, the terminal device establishes an access layer connection with the (R)AN through the Uu interface, and then the terminal device can transmit service data through the network. When the service is initiated, the network layer of the terminal device can obtain the traffic data description parameters of the service from the upper layer (such as the operating system or application), for example, the IP (Internet Protocol, network protocol) information of the target server, the application identifier of the service, the requested Whether the connection is an SMS connection or an internet connection, etc. Then, the terminal device establishes a corresponding PDU session for the service according to the locally stored URSP rules to transmit service data. Among them, the URSP rule includes the correspondence between the traffic data description parameters and the PDU session parameters, so that the terminal device can determine the corresponding PDU session parameters according to the traffic data description parameters of the service, and further establish the corresponding PDU session according to the PDU session parameters for transmission. business traffic data.

3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) introduced the concept of relay communication in the R13 (Release 13, 13th version) ProSe (Proximity Service, short-range communication service) architecture. As shown in FIG. 3 , in relay communication, the remote terminal device accesses the network through the relay terminal device. When a terminal device has both the ability to connect to an external data network through 5G and other networks, and also has the ProSe capability, the terminal device can act as a relay terminal device, and another terminal device with ProSe capability acts as a remote terminal device. As shown in Figure 3, the remote terminal device can establish direct communication with the relay terminal device through the PC5 interface, and realize the interaction with the external network through the PDU session established between the relay terminal device and the 5G network.

In one example, the relay end device transmits traffic data received from the remote end device to the network through a PDU session. At this time, the relay terminal device also establishes a corresponding PDU session according to its locally stored URSP rules for data transmission. However, in relay communication, since the traffic data of the service is received from the remote terminal device, the relay terminal device cannot obtain the traffic data description parameters of the service from its own upper layer (such as the operating system or application), so it cannot use the local The stored URSP rules correctly set the PDU session parameters, thus making it impossible to send traffic data from remote end devices to the network.

Based on this, the embodiment of the present application provides a parameter configuration method, which can be used to solve the above technical problem. Hereinafter, the technical solutions of the present application will be introduced and described through several embodiments.

Please refer to FIG. 4 , which shows a flowchart of a parameter configuration method provided by an embodiment of the present application, and the method can be applied to the relay communication system shown in FIG. 3 above. The method may include the following steps.

Step 410, the remote terminal device sends parameter configuration information to the relay terminal device, where the parameter configuration information includes: a first data packet filter and a first flow data description parameter corresponding to the first data packet filter.

As can be seen from the above description, the remote terminal device can send traffic data of the service to the relay terminal device, and the relay terminal device sends the traffic data to the network (eg, the core network). In this embodiment of the present application, the relay terminal device transmits the traffic data from the remote terminal device to the network through the PDU session. It is precisely because the traffic data of the service comes from the remote terminal device, the relay terminal device cannot obtain the traffic data description parameters of the service from its upper layer (such as the operating system or application), and thus cannot correctly set the PDU session parameters and determine the PDU. session.

Therefore, in this embodiment of the present application, for the traffic data of the first service, the remote terminal device may send parameter configuration information to the relay terminal device, where the parameter configuration information is used to configure the traffic data description parameters of the first service for the relay terminal device . In one example, the parameter configuration information is carried in a control plane message. Optionally, the control plane messages include connection establishment messages and/or connection modification messages. The connection establishment message is used to request to establish a communication connection between the remote terminal device and the relay terminal device; the connection modification message is used to request to modify the communication connection between the remote terminal device and the relay terminal device. In an example, a control plane message (such as a connection establishment message and/or a connection modification message) carries a QoS (Quality of Service, quality of service) rule, and the parameter configuration information is carried in the QoS rule. This embodiment of the present application does not limit the sending manner of the parameter configuration information. Exemplarily, the parameter configuration information may also be independent of the QoS rules, for example, the parameter configuration information is independently used as a control plane message, or the parameter configuration information and the QoS rules are carried in the same control plane message and the parameter configuration information is independent of the QoS rules. It should be understood that these should all fall within the protection scope of the present application.

In this embodiment of the present application, the parameter configuration information includes: a first data packet filter, and a first flow data description parameter corresponding to the first data packet filter.

The first data packet filter is used to match traffic data related to the first service, so that the first data packet filter can be used to determine whether a certain traffic data is traffic data related to the first service. This embodiment of the present application does not limit the type of the first data packet filter. In an example, the first data packet filter includes an IP data packet filter, optionally, the IP data packet filter includes at least one of the following: the source IP address of the first service, the destination IP address of the first service, the first The source port number of a service, the destination port number of the first service, and the protocol type of the first service. In another example, the first data packet filter includes an Ethernet data packet filter, optionally, the Ethernet data packet filter includes at least one of the following: the source MAC (Media Access Control or Medium Access Control) of the first service , Media Access Control) address, the target MAC address of the first service, and the Ethernet type of the first service. In yet another example, the first data packet filter includes a short-range communication data packet filter, optionally, the short-range communication data packet filter includes at least one of the following: a source layer 2 identifier of the first service, a first service The target Layer 2 identifier and the service type of the first service.

The first traffic data description parameter is used to identify the traffic data related to the first service, so when a certain traffic data is the traffic data related to the first service, the traffic data description parameter corresponding to the traffic data is the first traffic data description parameter. This embodiment of the present application does not limit the content of the first traffic data description parameter. In an example, the first traffic data description parameter includes at least one of the following: application information of the first service, domain name information of the first service, connection information requested by the application of the first service, and connection information provided by the relay terminal device with the first service. Relay Service Code (RSC) corresponding to the business. Optionally, the application information of the first service includes any one of the following: an application identifier of the first service, and an application code of the first service. Optionally, the connection information requested by the application of the first service includes any one of the following: SMS connection, Internet connection.

After receiving the parameter configuration information, the relay terminal device can determine the first PDU session based on the first flow data description parameter, match the data packets related to the first service based on the first data packet filter, and transmit the first PDU session through the first PDU session. A service-related data package. For the introduction and description of the determination process of the first PDU session, the transmission process of the data packet, etc., please refer to the following method embodiments, and details are not repeated here.

To sum up, in the technical solutions provided by the embodiments of the present application, when the remote terminal device accesses the network through the relay terminal device and transmits the traffic data of the service to the network, the parameter configuration information is sent to the relay terminal device through the remote terminal device, Therefore, the traffic data description parameters of the service are configured for the relay terminal device, and the technical problem that the relay terminal device cannot obtain the traffic data description parameters of the service from its own upper layer is solved. It is precisely because the relay terminal device can obtain the traffic data description parameters of the service through the parameter configuration information, and then the relay terminal device can further correctly set the PDU session parameters based on the traffic data description parameters of the service, so as to determine the PDU session based on the PDU session parameters. Transmit traffic data from remote end devices to the network.

In addition, in this embodiment of the present application, the parameter configuration information includes a data packet filter and a flow data description parameter corresponding to the data packet filter. On the one hand, the relay terminal device can determine the PDU session based on the flow data description parameter, and on the other hand, it can determine the PDU session based on the flow data description parameter. The data packet filter matches the traffic data of the service, and then transmits the traffic data of the service to the network through the determined PDU session. Compared with directly adding the traffic data description parameters to the traffic data of the service, it may lead to problems such as excessively large service data packets. Data description parameters, so that the remote terminal equipment does not need to add traffic data description parameters to the traffic data of the service, does not need to change the design of the service data packet, and does not increase the size of the service data packet, which is compatible with the original service data packet. design.

In the following, the determination process of the first PDU session, the transmission process of the data packet, etc. will be introduced and described.

In an example, the above method further includes the following steps.

Step 420, the relay terminal device acquires a URSP rule, where the URSP rule includes a correspondence between the flow data description parameters of at least one service and the PDU session parameters.

The relay terminal device can obtain the URSP rules and store them locally for subsequent use. In this embodiment of the present application, the URSP rule includes the correspondence between the traffic data description parameters of at least one service and the PDU session parameters, so that based on the traffic data description parameters of a certain service, the relay terminal device can obtain the traffic data description parameters from the URSP rule. The PDU session parameter corresponding to the flow data description parameter of the item of service.

It should be noted that this embodiment of the present application does not limit the order of execution between step 420 and the foregoing step 410. In an example, step 420 is executed before the foregoing step 410. For example, when the relay terminal device is powered on, the Acquire URSP rules, or, at any time between booting up and receiving parameter configuration information, the relay terminal device acquires URSP rules. In another example, step 420 is performed after step 410 described above. In yet another example, step 420 and step 410 described above are performed simultaneously.

Step 430, the relay terminal device determines a first PDU session parameter based on the URSP rule, where the first PDU session parameter is a PDU session parameter corresponding to the first flow data description parameter.

In this embodiment of the present application, the parameter configuration information sent by the remote terminal device to the relay terminal device includes the first traffic data description parameter, so that the relay terminal device can obtain the PDU session parameter corresponding to the first traffic data description parameter based on the URSP rule , that is, the first PDU session parameter.

Step 440, the relay terminal device determines a first PDU session based on the first PDU session parameter, where the first PDU session is used to transmit traffic data matching the first data packet filter.

Based on the first PDU session parameters, the relay terminal device can determine the first PDU session. Since the first PDU session parameter is a PDU session parameter corresponding to the first traffic data description parameter, and the first PDU session parameter is used to identify traffic data related to the first service, the first PDU session can be used to transmit the first service The relevant traffic data, that is, the traffic data matching the first packet filter.

This embodiment of the present application does not limit the manner in which the relay terminal device determines the first PDU session. In an example, the above step 440 includes: the relay terminal device establishes the first PDU session based on the first PDU session parameter. In another example, the above step 440 includes: the relay terminal device modifies the first PDU session based on the parameters of the first PDU session. In yet another example, the above step 440 includes: the relay terminal device acquires the first PDU session from at least one existing PDU session based on the first PDU session parameter.

This embodiment of the present application also does not limit the timing at which the relay terminal device determines the first PDU session. Exemplarily, after receiving the parameter configuration information, the relay terminal device determines the first PDU session, regardless of whether it receives traffic data related to the first service at this time. Exemplarily, after receiving the parameter configuration information and the flow data related to the first service, the relay terminal device determines the first PDU session. In the following, descriptions will be given for these two cases respectively.

In an example, the above method further includes: the remote terminal device sends a data packet to the relay terminal device; the relay terminal device matches the packet header of the data packet based on the first data packet filter; If the packet filter matches, the relay terminal device transmits the packet through the first PDU session.

It should be understood that, in this example, the remote terminal device can either send the data packet to the relay terminal device after sending the parameter configuration information; also can send the data packet to the relay terminal device before sending the parameter configuration information; When the parameter configuration information is sent, a data packet is sent to the relay terminal device, which is not limited in this embodiment of the present application. When receiving the data packet and receiving the parameter configuration information, the relay terminal device may use the first data packet filter to match the packet header of the data packet. When the header of the data packet matches the first data packet filter, it can be determined that the data packet is traffic data related to the first service, so that the relay terminal device can transmit the data packet through the first PDU session.

In another example, before step 430, the method further includes: the remote terminal device sends a data packet to the relay terminal device; the relay terminal device matches the packet header of the data packet based on the first data packet filter; In the case that the packet header matches the first data packet filter, the relay terminal device determines that the flow data description parameter corresponding to the data packet is the first flow data description parameter.

That is, in this example, the relay terminal device determines the PDU session after receiving the data packet. In this embodiment of the present application, the parameter configuration information includes the first flow data description parameter. Therefore, the relay terminal device will determine the first PDU session only when the flow data description parameter corresponding to the data packet is the first flow data description parameter. . In this example, the order of sending data packets and parameter configuration information is still not limited, that is, the remote terminal device can send data packets to the relay terminal device either after, before or at the same time as sending the parameter configuration information. In the case of receiving the data packet and receiving the parameter configuration information, the relay terminal device may use the first data packet filter to match the packet header of the data packet. When the header of the data packet matches the first data packet filter, it can be determined that the flow data description parameter corresponding to the data packet is the first flow data description parameter. After that, the relay terminal device can determine the first PDU session parameter based on the first flow data description parameter, and further determine the first PDU session. Based on this, in this example, after the above step 440, the method further includes: the relay terminal device transmits data packets through the first PDU session.

In the following, the parameter configuration method provided by the embodiment of the present application is described with two examples.

Please refer to FIG. 5 , which shows a flowchart of a parameter configuration method provided by an embodiment of the present application, and the method can be applied to the relay communication system shown in FIG. 3 above. The method may include the following steps.

Step 510: The remote terminal device sends parameter configuration information to the relay terminal device, where the parameter configuration information includes: a first data packet filter and a first flow data description parameter corresponding to the first data packet filter. The first data packet filter is used to match the flow data related to the first service; the first flow data description parameter is used to identify the flow data related to the first service.

Step 520, the relay terminal device acquires a URSP rule, where the URSP rule includes a correspondence between the flow data description parameters of at least one service and the PDU session parameters. This embodiment of the present application does not limit the execution timing of step 520, and FIG. 5 only takes that step 520 is executed before step 510 as an example for description.

Step 530, the relay terminal device determines a first PDU session parameter based on the URSP rule, where the first PDU session parameter is a PDU session parameter corresponding to the first flow data description parameter.

Step 540, the relay terminal device determines a first PDU session based on the first PDU session parameter, where the first PDU session is used to transmit traffic data matching the first data packet filter.

Step 550, the remote terminal device sends a data packet to the relay terminal device. This embodiment of the present application does not limit the execution timing of step 550, and FIG. 5 only takes that step 550 is executed after step 540 as an example for description.

Step 560, the relay terminal device matches the packet header of the data packet based on the first data packet filter.
