It should be understood that the terms "system" and "network" in this article are often used interchangeably in this article. The term "and/or" in this article is only an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, exist alone B these three situations. In addition, the character "/" in this text generally indicates that the associated objects before and after are in an "or" relationship.

In order to understand this application more clearly, the following briefly introduces the relevant content of the NCIS business to facilitate subsequent understanding of the solution of this application. However, it should be understood that the content introduced below is only for a better understanding of this application, and should not specifically limit this application.

NCIS services are mainly aimed at applications such as Augmented Reality (AR)/Virtual Reality (VR), games, etc., and have high requirements for service quality such as broadband speed, delay, packet loss rate, and high-speed codec. For example, for VR games, a 10Mb/s rate is required, and the packet loss rate cannot exceed 10E-4. The session established for the NCIS service is an NCIS session, and UEs in the same NCIS session can be considered to form an NCIS group, for example, a team in a game.

The UEs in the NCIS group can use different communication methods, for example, communication methods close to each other, communication methods far away from each other, etc. These methods can be used alone or in combination.

Communication methods that are close to each other, for example, you can use Device-to-Device (D2D) technology for broadcast or multicast, or establish a sidelink sidelink (also known as using PC5 interface) for one-to-one communication (single broadcast).

A communication method far away from each other, for example, the adopted communication link is UE-network-server-peer network-peer UE (also referred to as using Uu interface). Among them, Uu interface can support variable bandwidth from 1.4MHz to 20MHz, U means user network interface, u means universal.

For UEs that belong to the same group, these UEs can be from the same Public Land Mobile Network (PLMN) or from different PLMNs. For example, there are 5 UEs in an NCIS group, of which 3 are UEs of PLMN1 and 2 are UEs of PLMN2, then these 3 UEs of PLMN1 can communicate directly with each other on the PC5 interface using D2D technology, and at the same time It can communicate with two PLMN2 UEs using the Uu interface.

However, when UEs use the NCIS service for communication, the QoS mechanism of the PC5 interface of the NCIS service is not clear, so the quality of the communication cannot be guaranteed.

The embodiments of this application can be applied to data transmission for NCIS services, but it should be understood that the embodiments of this application can also be applied to data layer transmission of other services, for example, (Vehicle to Anything, V2X) services.

The wireless communication method provided by the embodiment of the present application will be described in detail below with reference to FIG. 2.

As shown in FIG. 2, a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application is shown, and the method may include steps 210-220.

210. The first terminal device determines the QoS parameter according to the address of the first server of the first application to which the first data belongs or the identity (ID) of the first application.

In the embodiment of the present application, the first terminal device may determine the corresponding QoS parameter according to the address of the first server of the first application to which the first data belongs, or may determine the QoS parameter according to the ID of the first application.

The first data in the embodiments of the present application may be chat application data or game application data, the corresponding first application may be a chat application or a game application, etc., and the first server of the corresponding first application may be a chat application server or Game application server, etc. The address of the first server of the first application to which the first data belongs can be the address of the chat application server or the address of the game application server, etc., and the ID of the first application can be the ID of the chat application or the game application ID etc.

In the embodiment of this application, when the same server address exists under different applications, the server address used to determine OoS parameters mentioned in the embodiment of this application may be the application ID + other used to distinguish the server from the application. Server information (this information can be an address). In different applications, when the same server address does not exist, the server address used to determine the OoS parameter mentioned in the embodiment of the present application may only include the server address but not the application ID.

Similarly, in the embodiment of the present application, when the same application ID exists under different operating systems, the embodiment of the present application mentions that the application ID used to determine OoS parameters may be the operating system ID + used to distinguish the application from Information about other applications of the operating system (the information can be an ID). Under different operating systems, when the same application ID does not exist, the application ID used to determine the OoS parameter mentioned in the embodiment of the present application may only include the application ID but not the ID of the operating system.

The QoS parameters in the embodiments of the present application may include broadband rate, time delay, packet loss rate, high-speed encoding and decoding, and so on. It should be understood that the first terminal device in the embodiment of the present application may select a QoS parameter group corresponding to the first data from multiple groups of QoS parameters.

Wherein, the broadband rate, time delay, etc. in each group of QoS parameters in the multiple groups of QoS parameters may be different. Taking the broadband rate in QoS parameters as an example, the broadband rates of multiple sets of QoS parameters can be 10Kb/s, 10Mb/s, and 10Gb/s, etc. Different applications may require different broadband rates.

For example, when the text data of the chat application is transmitted between the first terminal device and the second terminal device, the requirement on the broadband rate during the chat process may be relatively low, and the broadband rate of 10Kb/s may meet the requirement; and For game applications between terminal devices, the required broadband rate may be relatively high. Generally, a broadband rate of more than 10Mb/s is required to meet the requirements and make the game process smoother.

Therefore, the first terminal device can determine the appropriate QoS parameters according to the addresses of the servers of different applications or the IDs of different applications.

It should be understood that the numerical values in the embodiments of the present application are only examples, and may also be other numerical values, which should not specifically limit the present application.

It should be understood that in this embodiment of the application, the first terminal device may also send the first data to the second terminal device through other interfaces, which is not specifically limited in this application.

Specifically, FIG. 3 is a schematic diagram of data communication between the first terminal device and the second terminal device through the PC5 interface.

When the first terminal device performs data communication for the NCIS service through the PC5 interface, the data packet first reaches the NCIS layer, and combines the QoS rules matched by the PC5 interface to form the Service Data Adaptation Protocol (SDAP), which is carried on the side chain wireless bearer in. The side chain radio bearer may include a packet data convergence layer (Packet Data Convergence Protocol, PDCP), a radio link control layer (Radio Link Control, RLC), a media access control layer (Media Access Control, MAC), and a port physical layer ( Physical, PHY).

Optionally, in some embodiments, the first data includes the address of the first server or the ID of the first application.

In the embodiment of the present application, before the first terminal device sends the first data to the second terminal device, the QoS parameter may be determined according to the address of the first server of the first application to which the first data belongs or the ID of the first application. In order to use the determined QoS parameters to send the first data to the second terminal device through the PC5 interface.

The address of the first server of the first application to which the first data belongs or the ID of the first application may be included in the first data. For example, the first terminal device sends a piece of voice data to the second terminal device through a chat application. The voice data may include the address of the chat application server or the ID of the chat application. In this case, the first terminal device may first The address of the chat application server or the ID of the chat application included in the voice data determines the required QoS parameters, and then sends the voice data to the second terminal device through the PC5 interface according to the determined QoS parameters. Wherein, the first data may exist in the form of a data packet.

In the embodiment of the present application, the first data sent by the first terminal device through the PC5 interface may include the address or the due ID of the server, so that the second terminal device can obtain the first data according to the address of the server or the ID of the application. The application to which the data belongs.

For example, when the use scope of the first rule indicates that the first rule applies to all communications between PC5 interfaces, when the terminal device needs to send data to the second terminal device through any one of the PC5 interfaces, it can be based on The first rule determines QoS parameters.

In the case where the use scope of the first rule indicates that the first rule applies to communication between at least one PC5 interface, when the terminal device needs to send data to the second terminal device through any one of the at least one PC5 interface, it can be based on The first rule determines QoS parameters.

As shown in FIG. 7, a schematic flowchart of a wireless communication method according to an embodiment of the present application is shown.

As shown in Fig. 7, the wireless communication method may include steps 701-706.

701. The UE sends a registration request message to the AMF to request registration to the network. The request message carries the capability to support the NCIS service and the radio access technology (RAT) supported by the PC5 interface. The wireless communication technology may be LTE and/or NR.

702. The AMF establishes a UE policy link with the PCF, where the policy link includes the ID of the UE, the NCIS service capability, and the RAT supported by the PC5 interface.

703. The AMF sends a registration success message to the UE to notify the UE that the registration is successful. Wherein, step 702 can also be performed after 703.

704. The PCF asks the UDM for the subscription information of the UE, where the subscription information includes the ID of the UE.

705. If the UE has the NCIS service capability and the contract allows the UE to use the NCIS service, the PCF determines the QoS rule of the PC5 interface according to the information contained in the application function.

Among them, the information in the application function can include: PC5 information indication (indicating whether other parameters are only used for PC5 interface), group information, UE information, QoS requirements and application server address or application ID + server address (or it can be a It can distinguish the QoS parameters. In the subsequent steps, the corresponding relationship between the QoS requirements and the application server address or application ID + server address can also be multiplexed. Uu interface.

PCF uses the information provided above to write the target address in the packet filter in the QoS rules of the PC5 interface as the address of the server. The address of the server can be the server address that does not include the application ID or the application ID + Differentiate the server from the information of other servers in the application; convert QoS requirements into QoS parameters, where the QoS parameters can be included in the QoS rules of the PC5 interface, or they can be separate parameters.

In the embodiment of this application, when there is no server with the same address in different applications, the target address in the packet filtering in the QoS rule of the PC5 interface can be written as the address of the server, and the address of the server can be different. The address of the server that includes the application ID. When different applications have the same server address, the target address in the packet filtering in the QoS rule of the PC5 interface can be written as the address of the server. The address of the server can be the application ID + used to distinguish the server from Information about other servers of the application.

Of course, in some cases, the system may also set a default QoS rule, and the default QoS rule indicates the correspondence between the applied ID settings and the QoS parameters.

In the embodiments of this application, when there are no identical application IDs under different operating systems, the target address in the packet filtering in the QoS rule of the PC5 interface can be written as the application ID, and the application ID can be excluding The application ID of the operating system ID. When having the same application ID under different operating systems, the target address in the packet filtering in the QoS rule of the PC5 interface can be written as the application ID. The application ID can be the operating system ID + used to distinguish the application from Information about other applications of the operating system.

QoS rules can be applied to UE, PC5 interface, application or group.

After determining the foregoing rules, the PCF stores the foregoing determined packet filtering, QoS parameters, and the use range of the QoS rules in the UE policy container, and sends the policy container and the ID of the UE to the AMF.

706. The AMF sends the UE's policy container to the UE through DL NAS transmission.

As shown in FIG. 8, another schematic flowchart of a wireless communication method according to an embodiment of the present application is shown.

As shown in FIG. 8, the wireless communication method may include steps 801-804.

801. The UE sends a PDU session establishment request message to the SMF. The request message contains the session ID, NCIS indication, and group ID. The NCIS indication is used to indicate that the session is used for NCIS services, and the form of expression may be for the NCIS data network. Name (Data Network Name, DNN) and/or Single-Network Slice Selection Auxiliary Information (S-NSSAI), and the group ID is the NCIS group ID to which the UE belongs.

802. The SMF sends a session establishment request message to the PCF, which contains the UE ID, session ID, group ID, and NCIS indication.

803, PCF generates PCC rules for Uu interface, according to business information, for example, NCIS instructions, information provided by AF, for PC5 information instructions, indicate whether it can be used for PC5 interface, group information, UE information, QoS requirements and server address ( Or it can be a parameter that can distinguish QoS. In the subsequent steps, the provided parameters can be used to determine the QoS when filtering data to determine whether the QoS-related parameters in the PCC rule can be used for the PC5 interface. If Yes, add the PC5 indication to the PCC rules to indicate that it can be used for the PC5 interface. The server address mentioned here may be a server address that does not include an application ID or an application ID + information used to distinguish the server from other servers of the application.

Of course, in some cases, the system can also set default QoS rules, that is, the correspondence between application ID and QoS parameters. The application ID can be an application ID that does not include the operating system ID or an operating system ID + used to distinguish the application. Information about other applications of the operating system.

QoS rules can be applied to UE, PC5 interface, application or group.

The PCF sends a session establishment response to the SMF, which can include PCC rules and the scope of use of QoS.

804. The SMF determines the QoS rule according to the PCC rule. If there is a PC5 indication in the PCC rule, the PC5 indication and the range of use are included in the QoS rule. SMF puts the QoS rules in the successful establishment of the PDU session and sends them to the NAS layer of the UE.

The above process explains the determination of the PC5 interface QoS rules in the NCIS service. The following will introduce how the UE uses the determined QoS rules for data transmission. Figure 9 shows a schematic diagram of the UE using the NCIS service to perform data transmission through the PC5 interface. As shown in Figure 9, steps 901-904 may be included.

901. After receiving the QoS rule, the NAS layer of the UE transmits the QoS rule indicated by the PC5 to the PC5 layer.

902. When an application in the UE needs to transmit data, the application determines that it needs to use the PC5 interface to transmit data, calls the application programming interface (API) of the PC5 interface, and provides data, the server address corresponding to the data, and the server address It can be the address of the server that does not include the application ID or the application ID + information that distinguishes the server from the application server.

903. The operating system includes the application data in the PDU (Internet Protocol (IP) or Ethernet), and the destination address and port number in the header of the PDU.

In the case of unicast, the PDU includes the address port number of the peer UE; in the case of multicast, the PDU includes the address port number corresponding to the group.

The operating system sends the packaged PDU and the server address corresponding to the data to the PC5 layer, for example, the D2D layer, the V2X layer, the NCIS layer, etc. .

904. The PC5 layer uses packet filtering on the PDU to determine the corresponding QoS flow. When matching, the server address is used as the destination address and port number instead of the address port number in the header. After determining the QoS flow, the PC5 determines the data and quality of service. The flow ID (QoS Flow ID, QFI) is sent to the access layer (Access Stratum, AS).
