Description

Parameter configuration method, device, equipment and storage medium

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a parameter configuration method, device, equipment and storage medium.

Background

In a 5G (5 th-Generation, fifth Generation mobile communication technology) Network system architecture, a terminal device (UE) establishes AN Access layer connection with AN (R) AN (Radio) Access Network through a Uu interface, and then, the terminal device may transmit service data through a Network.

When a service is initiated, the network layer of the terminal device may obtain the traffic data description parameters of the service from an upper layer (such as an operating system or an application), and then establish a corresponding PDU (Protocol Data Unit ) session for the service according to the locally stored urs (UE Route Selection Policy, user routing policy) rule for transmission of service data. The URSP rule includes a correspondence between the flow data description parameter and the PDU session parameter, so that the terminal device can determine a corresponding PDU session parameter according to the flow data description parameter of the service, and further establish a corresponding PDU session according to the PDU session parameter to transmit the flow data of the service. In Relay communication, a Remote UE (Remote terminal device) accesses a network through a Relay UE (Relay terminal device). In the related art, a relay terminal device transmits traffic data received from a remote terminal device to a network through a PDU session. At this time, the relay terminal device also establishes a corresponding PDU session according to its locally stored urs rule for data transmission.

However, in the relay communication, since the traffic data is received from the remote terminal device, the relay terminal device cannot obtain the traffic data description parameter of the traffic from its own upper layer (e.g., an operating system or an application), and thus cannot correctly set the PDU session parameter using the locally stored urs rule, and thus cannot realize the transmission of the traffic data from the remote terminal device to the network.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

The technical scheme provided by the embodiment of the application can be applied to various communication systems, for example: GSM (Global System of Mobile Communication, global system for mobile communications), CDMA (Code Division Multiple Access ) system, WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) system, GPRS (General Packet Radio Service ), LTE (Long Term Evolution, long term evolution) system, FDD (Frequency Division Duplex, LTE frequency division duplex) system, TDD (Time Division Duplex, LTE time division duplex) system, UMTS (Universal Mobile Telecommunication System, universal mobile telecommunications system), wiMAX (Worldwide Interoperability for Microwave Access ) communication system, 5GS (5 th-Generation System, fifth generation mobile telecommunications system) or New air interface (New Radio, NR) system, or subsequent other evolved systems, etc.

Referring to fig. 1, a schematic diagram of a 5G network system architecture according to an embodiment of the present application is shown. As shown in fig. 1, the system architecture 100 may be composed of UEs, (R) AN, core, and DN (Data Network). The UE, (R) AN, core are main components constituting the system architecture 100, and logically they can be divided into two parts, i.e. a user plane and a control plane, where the control plane is responsible for management of the mobile network, and the user plane is responsible for transmission of service data. In fig. 1, the NG2 reference point is located between the (R) AN control plane and the Core control plane, the NG3 reference point is located between the (R) AN user plane and the Core user plane, and the NG6 reference point is located between the Core user plane and the data network. Wherein:

UE: the method is an entrance for interaction between the mobile user and the network, can provide basic computing capacity and storage capacity, displays a service window for the user, and accepts user operation input. The UE may establish a signal connection, a data connection with the (R) AN using a next generation air interface technology, thereby transmitting control signals and traffic data to the mobile network.

(R) AN: similar to a base station in a traditional network, the network access function is provided for authorized users in a specific area by being deployed at a position close to the UE, and user data can be transmitted by using transmission tunnels with different qualities according to the level of the users, the service requirements and the like. The RAN can manage own resources, reasonably utilize, provide access service for the UE according to the requirement, and forward control signals and user data between the UE and a core network.

Core: and the system is responsible for maintaining subscription data of the mobile network, managing network elements of the mobile network, and providing session management, mobility management, policy management, security authentication and other functions for the UE. Providing network access authentication for the UE when the UE is attached; when the UE has a service request, network resources are allocated to the UE; updating network resources for the UE when the UE moves; and when the UE is idle, providing a quick recovery mechanism for the UE: releasing network resources for the UE when the UE is detached; when the UE has service data, a data routing function is provided for the UE, such as forwarding uplink data to the DN: or receives the downlink data of the UE from the DN and forwards the downlink data to the (R) AN, so as to be sent to the UE.

DN: is a data network for providing business services for users, and generally, a client is located in a UE, and a server is located in the data network. The data network may be a private network, such as a local area network, or an external network not under the control of an operator, such as the Internet, or a proprietary network co-deployed by an operator, such as for configuring 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 functions); the core network control plane includes AUSF (Authentication Server Function ), AMF (Core Access and Mobility Management Function, core network access and mobility management function), SMF (Session Management Function ), UDM (Unified Data Management, unified data management), PCF (Policy Control Function ), AF (Application Function, application function). The functions of these functional entities are as follows:

UPF: executing user data packet forwarding according to the routing rule of the SMF;

AUSF: performing 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;

AF: user application management.

In the system architecture shown in fig. 2, the Uu interface is a reference point between the UE and the (R) AN, and the UE establishes AN access layer connection with the (R) AN through the Uu interface, and interacts with AN access layer message and wireless data transmission; the N1 interface is a reference point between the UE and the AMF, the UE establishes non-access stratum (None Access Stratum, NAS) connection with the AMF through the N1 interface, and NAS information is interacted; the N2 interface is a reference point of (R) AN and AMF and is used for sending NAS information and the like; the N3 interface is a reference point between (R) AN and UPF, and is used for transmitting data of user plane, etc.; the N4 interface is a reference point between the SMF and the UPF, and is used for transmitting information such as tunnel identification information, data buffer indication information, downlink data notification message, and the like of the N3 connection; the N6 interface is a reference point between the UPF and the DN, and is used for transmitting data of the user plane, etc.

It should be noted that the names of interfaces between the network elements in fig. 1 and fig. 2 are only an example, and the names of interfaces in the specific implementation may be other names, which are not limited in particular in the embodiment of the present application. The names of the individual network elements (e.g., SMF, AF, UPF, etc.) included in fig. 1 and 2 are also merely examples, and the functions of the network elements themselves are not limited. In 5G and other networks in the future, the foregoing network elements may also be named, which is not specifically limited in the embodiments of the present application. For example, in a 6G network, some or all of the above network elements may use the terminology in 5G, possibly use other names, etc., which are described in detail herein, and will not be described in detail herein. Furthermore, it should be understood that the names of the transmitted messages (or signaling) between the various network elements described above are also merely an example, and do not constitute any limitation on the functionality of the messages themselves.

In one example, the terminal device establishes AN access stratum connection with the (R) AN through a Uu interface, after which the terminal device may conduct transmission of service data through the network. When the service is initiated, the network layer of the terminal device may obtain the traffic data description parameters of the service from an upper layer (such as an operating system or an application), for example, IP (Internet Protocol, network protocol) information of the target server, an application identifier of the service, whether the requested connection is a short message connection or an internet connection, and the like. Then, the terminal device establishes a corresponding PDU session for the service according to the locally stored URSP rule to transmit the service data. The URSP rule includes a correspondence between the flow data description parameter and the PDU session parameter, so that the terminal device can determine a corresponding PDU session parameter according to the flow data description parameter of the service, and further establish a corresponding PDU session according to the PDU session parameter to transmit the flow data of the service.

The 3GPP (3 rd Generation Partnership Project, third generation partnership project) introduced the concept of relay communication in the R13 (Release 13 ) ProSe (Proximity Service, short range communication service) architecture. As shown in fig. 3, in relay communication, a remote terminal device accesses a network through a relay terminal device. When a terminal device has both the capability of connecting to an external data network via a network such as 5G and ProSe capability, the terminal device may act as a relay terminal device and another ProSe capable terminal device may act as a remote terminal device. As shown in fig. 3, the remote terminal device may establish direct communication with the relay terminal device through a PC5 interface, and implement interaction with an external network through a PDU session established between the relay terminal device and a 5G network or the like.

In one example, the relay terminal device transmits traffic data received from the remote terminal 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 urs rule for data transmission. However, in the relay communication, since the traffic data is received from the remote terminal device, the relay terminal device cannot obtain the traffic data description parameter of the traffic from its own upper layer (e.g., an operating system or an application), and thus cannot correctly set the PDU session parameter using the locally stored urs rule, and thus cannot realize the transmission of the traffic data from the remote terminal device to the network.

Based on this, the embodiment of the application provides a parameter configuration method, which can be used for solving the technical problems. The following describes the technical solution of the present application through several embodiments.

Referring to fig. 4, a flowchart of a parameter configuration method according to an embodiment of the present application is shown, and the method may be applied to the relay communication system shown in fig. 3. The method may comprise the following steps.

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

As is apparent from the above description, the remote terminal device may send traffic data to the relay terminal device, and the relay terminal device may send the traffic data to a network (e.g., a core network). In the embodiment of the application, the relay terminal equipment transmits traffic data from the remote terminal equipment to the network through the PDU session. 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 an upper layer (such as an operating system or an application) of the relay terminal device, and thus cannot correctly set the PDU session parameters and determine the PDU session.

Therefore, in the 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 parameter 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 message comprises a connection setup message and/or a connection modification message. The connection establishment message is used for requesting to establish communication connection between the remote terminal equipment and the relay terminal equipment; the connection modification message is used to request modification of the communication connection between the remote terminal device and the relay terminal device. In one example, control plane messages (e.g., connection setup messages and/or connection modification messages) carry QoS (Quality of Service ) rules in which parameter configuration information is carried. The embodiment of the application does not limit the sending mode of the parameter configuration information. For example, the parameter configuration information may also be independent of the QoS rule, e.g., the parameter configuration information is independent of the QoS rule as a control plane message, and e.g., the parameter configuration information is carried in the same control plane message as the QoS rule and the parameter configuration information is independent of the QoS rule. It should be understood that these are all intended to be within the scope of the present application.

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

The first packet filter is configured to match traffic data associated with the first service, so that the first packet filter may be configured to determine whether a certain traffic data is traffic data associated with the first service. The type of the first packet filter is not limited in the embodiments of the present application. In one example, the first packet filter comprises an IP packet filter, optionally comprising at least one of: the method comprises the steps of a source IP address of a first service, a target IP address of the first service, a source port number of the first service, a target port number of the first service and a protocol type of the first service. In another example, the first packet filter comprises an ethernet packet filter, optionally the ethernet packet filter comprises at least one of: the source MAC (Media Access Control or Medium Access Control, medium access control) address of the first service, the destination MAC address of the first service, the ethertype of the first service. In yet another example, the first packet filter comprises a near field communication packet filter, optionally comprising at least one of: the method comprises the steps of a source layer two identifier of a first service, a target layer two identifier of the first service and a service type of the first service.

The first traffic data description parameter is used for identifying traffic data related to the first service, so that when certain traffic data is traffic data related to the first service, the traffic data description parameter corresponding to the traffic data is the first traffic data description parameter. The content of the first flow data description parameter is not limited in the embodiments of the present application. In one example, the first traffic data description parameter includes at least one of: application information of the first service, domain name information of the first service, connection information of an application request of the first service, and a relay service code (Relay Service Code, RSC) corresponding to the first service, which is provided by the relay terminal device. Optionally, the application information of the first service includes any one of the following: application identification of the first service, application coding of the first service. Optionally, the connection information requested by the application of the first service includes any one of the following: and (5) short message connection and Internet connection.

After receiving the parameter configuration information, the relay terminal device may determine a first PDU session based on the first traffic data description parameter, match a first service related data packet based on the first packet filter, and transmit the first service related data packet through the first PDU session. For description about the determining procedure of the first PDU session, the transmission procedure of the data packet, etc., please refer to the following method embodiments, which are not repeated here.

In summary, according to the technical scheme provided by the embodiment of the 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 remote terminal device sends the parameter configuration information to the relay terminal device, so that 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 an upper layer of the relay terminal device is solved. The relay terminal equipment can obtain the flow data description parameters of the service through the parameter configuration information, and further the relay terminal equipment can further correctly set PDU session parameters based on the flow data description parameters of the service so as to determine PDU session based on the PDU session parameters, thereby realizing the transmission of the flow data from the remote terminal equipment to the network.

In addition, in the embodiment of the present application, the parameter configuration information includes a packet filter and a flow data description parameter corresponding to the packet filter, where the relay terminal device may determine, on one hand, a PDU session based on the flow data description parameter, and on the other hand, may match, based on the packet filter, flow data of a service, and then transmit, to the network, the flow data of the service through the determined PDU session. Compared with the problem that the traffic data description parameters are directly added into traffic data of the traffic, the traffic data packets can be excessively large, and the like, in the embodiment of the application, because the remote terminal equipment configures the traffic data description parameters of the traffic to the relay terminal equipment through the parameter configuration information, the remote terminal equipment does not need to add the traffic data description parameters into the traffic data of the traffic, does not need to change the design of the traffic data packets, does not increase the size of the traffic data packets, and is compatible with the design of the original traffic data packets.

Next, description will be made with respect to a determination procedure of the first PDU session, a transmission procedure of the data packet, and the like.

In one example, the above method further comprises the following steps.

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

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

It should be noted that, in the embodiment of the present application, the execution sequence between the step 420 and the step 410 is not limited, and in one example, the step 420 is performed before the step 410, for example, the relay terminal device acquires the urs rule at the time of starting up, or the relay terminal device acquires the urs rule at any time between starting up and receiving the parameter configuration information. 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.

In step 430, the relay terminal device determines a first PDU session parameter based on the urs p rule, the first PDU session parameter being a PDU session parameter corresponding to the first traffic 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 a first flow data description parameter, so that the relay terminal device may obtain, based on the urs rule, a PDU session parameter corresponding to the first flow data description parameter, that is, a first PDU session parameter.

In step 440, the relay terminal device determines a first PDU session based on the first PDU session parameter, the first PDU session being used for transmitting traffic data matching the first packet filter.

Based on the first PDU session parameters, the relay terminal device may determine a 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 may be used to transmit the traffic data related to the first service, i.e. the traffic data matched with the first packet filter.

The manner in which the relay terminal device determines the first PDU session in the embodiment of the present application is not limited. In one example, the step 440 includes: the relay terminal device establishes a first PDU session based on the first PDU session parameter. In another example, the step 440 includes: the relay terminal device modifies the first PDU session based on the first PDU session parameter. In yet another example, the step 440 includes: the relay terminal device acquires a first PDU session from the existing at least one PDU session based on the first PDU session parameter.

The embodiment of the application also does not limit the time for determining the first PDU session for the relay terminal equipment. The relay terminal device, upon receiving the parameter configuration information, illustratively determines the first PDU session, regardless of whether first service related traffic data is received at this time. The relay terminal device, upon receiving the parameter configuration information and receiving the first service related traffic data, illustratively, determines a first PDU session. The following description will be made for these two cases, respectively.

In one example, the method further comprises: the remote terminal device sends a data packet to the relay terminal device; the relay terminal equipment matches the packet header of the data packet based on the first data packet filter; in case that the header of the data packet matches the first data packet filter, the relay terminal device transmits the data packet through the first PDU session.

It should be appreciated that in this example, the remote terminal device may send a data packet to the relay terminal device after sending the parameter configuration information; or before sending the parameter configuration information, sending a data packet to the relay terminal equipment; the data packet may also be sent to the relay terminal device while the parameter configuration information is being sent, which is not limited in the embodiment of the present application. When receiving the data packet and the parameter configuration information, the relay terminal device may match the packet header of the data packet by using the first data packet filter. And under the condition that the packet head of the data packet is matched with the first data packet filter, determining that the data packet is traffic data related to the first service, so that the relay terminal equipment can transmit the data packet through the first PDU session.

In another example, before the step 430, the method further includes: the remote terminal device sends a data packet to the relay terminal device; the relay terminal equipment matches the packet header of the data packet based on the first data packet filter; and under the condition that the packet head of the data packet is matched with the first data packet filter, the relay terminal equipment determines the flow data description parameter corresponding to the data packet as 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 a first flow data description parameter, so the relay terminal device determines 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 sending sequence of the data packet and the parameter configuration information is not limited yet, that is, the remote terminal device may send the data packet to the relay terminal device either after, before or simultaneously with the sending of the parameter configuration information. In the case of receiving the data packet and receiving the parameter configuration information, the relay terminal device may match the packet header of the data packet using the first data packet filter. Under the condition that the packet head of the data packet is matched with the first data packet filter, the flow data description parameter corresponding to the data packet can be determined to be the first flow data description parameter. The relay terminal device may then determine the first PDU session parameter based on the first traffic data description parameter and further determine the first PDU session. Based on this, in this example, following step 440 described above, further includes: the relay terminal device transmits data packets through the first PDU session.

The parameter configuration method provided in the embodiment of the present application will be described in two examples.

Referring to fig. 5, a flowchart of a parameter configuration method according to an embodiment of the present application is shown, and the method may be applied to the relay communication system shown in fig. 3. The method may comprise the following steps.

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

In step 520, the relay terminal device obtains a urs rule, where the urs rule includes a correspondence between a flow data description parameter and a PDU session parameter of at least one service. The execution timing of step 520 is not limited in the embodiment of the present application, and fig. 5 is only described as an example in which step 520 is executed before step 510.

In step 530, the relay terminal device determines a first PDU session parameter based on the urs p rule, the first PDU session parameter being a PDU session parameter corresponding to the first traffic data description parameter.

In step 540, the relay terminal device determines a first PDU session based on the first PDU session parameter, the first PDU session being used to transmit traffic data matching the first packet filter.

In step 550, the remote terminal device sends the data packet to the relay terminal device. The execution timing of step 550 is not limited in this embodiment, and fig. 5 is only described as an example in which step 550 is executed after step 540.

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

In step 570, the relay terminal device transmits the data packet through the first PDU session in case that the header of the data packet matches the first data packet filter.

Referring to fig. 6, a flowchart of a parameter configuration method according to an embodiment of the present application is shown, and the method may be applied to the relay communication system shown in fig. 3. The method may comprise the following steps.
