The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone.

For a clearer understanding of the present application, the following description will be given for brief description of related contents regarding NCIS services, so as to facilitate subsequent understanding of the schemes of the present application. It should be understood that the following description is only for better understanding of the present application and should not be construed as limiting the present application in any way.

The NCIS service is mainly aimed at applications such as augmented Reality (Augmented Reality, AR)/Virtual Reality (VR), games, and the like, and has high requirements on service quality such as broadband rate, time delay, packet loss rate, high-speed encoding and decoding, and the like. For example, for VR games, a 10Mb/s rate is required, and the packet loss rate may not exceed 10E-4. The session established for the NCIS service is an NCIS session, and UEs in the same NCIS session may be considered to constitute an NCIS group, for example: team formation in game.

The UEs in the NCIS group may use different communication methods, for example, a communication method of approaching each other, a communication method of separating from each other, etc., and these methods may be used alone or in combination.

Communication approaches in close proximity to each other may be, for example, broadcast or multicast using Device-to-Device (D2D) technology, or set up side-chain sidelink (also referred to as using a PC5 interface) for 1-to-1 communication (unicast).

The communication means far from each other, for example, the communication link employed is UE-network-server-peer network-peer UE (also referred to as using Uu interface). Wherein the Uu interface can support variable bandwidths of 1.4MHz to 20MHz, U denotes a user network interface, and U denotes a general purpose.

For UEs belonging to the same group, these UEs may be from the same public land mobile network (Public Land Mobile Network, PLMN) or from different PLMNs. For example, there are 5 UEs in an NCIS group, 3 of which are PLMN1 UEs and 2 of which are PLMN2 UEs, the 3 PLMN1 UEs may communicate directly with each other over the PC5 interface using D2D technology, while communicating with the 2 PLMN2 UEs using Uu interface.

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

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

The wireless communication method provided in the embodiment of the present application is described in detail below with reference to fig. 2.

As shown in fig. 2, a schematic flow chart of a wireless communication method 200 provided in accordance with an embodiment of the present application is shown, which may include steps 210-220.

210, the first terminal device determines the QoS parameter according to an address of a first server of a first application to which the first data belongs or an Identity (ID) of the first application.

In this 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.

In the embodiment of the present application, the first data may be data of a chat application or data of a game application, the corresponding first application may be a chat application or a game application, the corresponding first server of the first application may be a chat application server or a game application server, an address of the first server of the first application to which the first data belongs may be an address of the server of the chat application or an address of the server of the game application, and an ID of the first application may be an ID of the chat application or an ID of the game application.

In the embodiment of the present application, when the same server address exists under different applications, the server address for determining the OoS parameter mentioned in the embodiment of the present application may be application id+information (the information may be an address) for distinguishing the server from other servers of the application. In a case where the same server address does not exist under different applications, the server address for determining the OoS parameter mentioned in the embodiment of the present application may include only the address of the server and 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 for determining the OoS parameter may be the operating system id+information (the information may be an ID) for distinguishing the application from other applications of the operating system. When the same application ID does not exist under different operating systems, the application ID for determining the OoS parameter mentioned in the embodiment of the present application may include only the application ID and not the ID of the operating system.

The QoS parameters in the embodiments of the present application may include wideband rate, delay, packet loss rate, high-speed codec, etc. It should be understood that the first terminal device in the embodiment of the present application may select the QoS parameter set corresponding to the first data from the plurality of sets of QoS parameters.

Wherein the wideband rate, delay, etc. may be different in each of the plurality of sets of QoS parameters. Taking the wideband rate in the QoS parameters as an example, the wideband rates of the multiple sets of QoS parameters may be 10Kb/s, 10Mb/s, 10Gb/s, etc., respectively, and different wideband rates may be required for different applications.

For example, when text data of a chat application is transmitted between a first terminal device and a second terminal device, the requirement on the broadband rate in the chat process may be relatively low, and the requirement may be met by the broadband rate of 10 Kb/s; for the application of games between terminal devices, the wideband rate which may be needed is high, and the wideband rate above 10Mb/s is generally needed to meet the requirement, so that the game process is smooth.

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

It should be understood that the numerical values in the embodiments of the present application are only illustrative, but may be other numerical values, and should not be limited to the specific values.

220, the first terminal device sends the first data to the second terminal device through the PC5 interface according to the QoS parameter.

In this embodiment of the present application, after the first terminal device determines the required QoS parameters, the first terminal device may send the first data to the second terminal device through the PC5 interface. It should be understood that, in the embodiment of the present 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 showing the data communication between the first terminal device and the second terminal device through the PC5 interface.

When the first terminal device performs data communication through the PC5 interface aiming at NCIS service, the data packet firstly reaches the NCIS layer, forms a service data communication protocol (Service Data Adaptation Protocol, SDAP) by combining the QoS rule matched with the PC5 interface, and is borne in the side-chain radio bearer. 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 medium access control layer (Media Access Control, MAC), and a port Physical layer (PHY).

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

In this 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, so that the determined QoS parameter is used to send the first data to the second terminal device through the PC5 interface.

Wherein an address of a first server of a first application to which the first data belongs or an ID of the first application may be included in the first data. For example, the first terminal device may send a piece of voice data to the second terminal device through the chat application, where the voice data may include an address of a server of the chat application or an ID of the chat application, in which case the first terminal device may first determine a required QoS parameter according to the address of the server of the chat application or the ID of the chat application included in the voice data, and then send the voice data to the second terminal device through the PC5 interface according to the determined QoS parameter. Wherein the first data may be in the form of a data packet.

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

In the method for wireless communication provided in the embodiment of the present application, since the first data sent by the first terminal device to the second terminal device includes the address of the first server of the first application to which the first data belongs or the ID of the first application, the first terminal device can determine the required QoS parameter according to the address of the first server or the ID of the first application, and further can send the first data to the second terminal device according to the QoS parameter, so that the quality of data communication can be ensured.

Optionally, in some embodiments, as shown in fig. 4, the wireless communication method 200 may further include step 230. Wherein this step 230 may be performed prior to step 210.

230, the first terminal device obtains the first data including the address of the first server at an application layer.

In the embodiment of the present application, the first terminal device may acquire, at an application layer, first data including an address of the first server. For example, the first terminal device may send voice data to the second terminal device through the chat application, where the voice data may be stored in the application layer, and the first terminal device may obtain voice data including an address of the chat application server in the application layer, so that the first terminal device determines a required QoS parameter according to the address of the chat application server.

Optionally, in some embodiments, the determining, by the first terminal device, a QoS parameter according to an address of a first server of a first application to which the first data belongs or an ID of the first application includes: the first terminal equipment determines a QoS parameter corresponding to the first data based on the address of the first server and at least one first rule, wherein the first rule indicates the corresponding relation between the address of the server and the QoS parameter.

In this embodiment of the present application, when the first terminal device determines the QoS parameter, the QoS parameter may be determined according to an address of a first server of a first application to which the first data belongs and at least one first rule, where the first rule may indicate a correspondence between the address of the server and the QoS parameter.

In this embodiment of the present application, the first rule may indicate a correspondence between an address of the server and QoS parameters. Wherein a server address may correspond to a set of QoS parameters, a set of QoS parameters may correspond to one or more server addresses, or a server address may correspond to multiple sets of QoS parameters.

For example, if one server address corresponds to a set of QoS parameters, for example, the address of the server of the chat application corresponds to QoS parameter set 1, the address of the server of the game application corresponds to QoS parameter set 2, and when the first terminal device determines that the server address to which the first data belongs is the server address of the chat application, the first terminal device may determine from the correspondence that the QoS parameter set corresponding to the address of the server of the chat application is QoS parameter set 1; if one server address corresponds to multiple sets of QoS parameters, for example, the address of the chat application server corresponds to QoS parameter set 1 and QoS parameter set 2, the address of the game application server corresponds to QoS parameter set 3 and QoS parameter set 4, and when the first terminal device determines that the server to which the first data belongs is the chat application server, the first terminal device can determine that the QoS parameter set corresponding to the address of the chat application server is QoS parameter set 1 and QoS parameter set 2 from the corresponding relationship, and then determine a proper QoS parameter set from QoS parameter set 1 and QoS parameter set 2 to transmit data.

In this embodiment of the present application, each first rule may be a correspondence between a set of QoS parameters and at least one address (i.e., a set of QoS parameters may correspond to a plurality of addresses), or may also be a correspondence between a plurality of sets of QoS parameters and a plurality of addresses.

In the embodiment of the present application, there may be a plurality of first rules, for example, the first rule 1 indicates a correspondence between an address of a chat application server and QoS parameters, the first rule 2 indicates a correspondence between an address of a game application server and QoS parameters, and so on.

Optionally, in some embodiments, the terminal device determines the at least one first rule based on a range of use of each first rule.

In this embodiment of the present application, the usage range of each first rule in each at least one first rule may be different, so the terminal device may determine the at least one first rule according to the usage range of the first rule.

Optionally, in some embodiments, the usage scope of the first rule indicates that the first rule applies to all communications of the PC5 interface, the first rule applies to at least one PC5 connected communication, the first rule applies to at least one group.

In this embodiment, when communication is performed between terminal devices through the PC5 interfaces, there may be multiple PC5 interfaces, and the usage range of the first rule may indicate that the first rule is applicable to communication between all PC5 interfaces, may indicate that the first rule is applicable to communication between at least one PC5 interface, and may also indicate that the first rule is applicable to at least one group.

For example, in the case where the usage range of the first rule indicates that the first rule applies to communications between all PC5 interfaces, when the terminal device needs to transmit data to the second terminal device through any one of the PC5 interfaces, the QoS parameter may be determined according to the first rule.

In case the usage range of the first rule indicates that the first rule applies to the communication between the at least one PC5 interface, the QoS parameter may be determined according to the first rule when the terminal device needs to send data to the second terminal device through any one of the at least one PC5 interface.

The usage range of the first rule may indicate that the first rule is applicable to at least one group, since the first terminal device may belong to different groups, e.g. group 1, group 2 and group 3, while the usage range of the first rule is group 1 and group 2, and when the terminal device needs to communicate within group 1 or group 2, the first terminal device determines QoS parameters according to the first rule.

The above embodiment illustrates that the first terminal device may determine the QoS parameter according to the address of the first server of the first application to which the first data belongs, and of course, the first terminal device may determine the QoS parameter according to the ID of the first application, and the determination of the QoS parameter by the first terminal device according to the ID of the first application will be described below.

Optionally, in some embodiments, the determining, by the first terminal device, a QoS parameter according to an address of a first server of a first application to which the first data belongs or an ID of the first application includes: the terminal equipment determines a QoS parameter corresponding to the first data based on the ID of the first application and at least one second rule, wherein the second rule indicates the corresponding relation between the ID of the application and the QoS parameter.

In this embodiment of the present application, when the first terminal device determines the QoS parameter, the QoS parameter may be determined according to an ID of a first application to which the first data belongs and at least one second rule, where the second rule may indicate a correspondence between the ID of the application and the QoS parameter.

In the embodiment of the present application, the second rule may indicate a correspondence between the applied ID and the QoS parameter. Wherein, an application ID may correspond to a set of QoS parameters, a set of QoS parameters may correspond to one or more application IDs, or an application ID may correspond to multiple sets of QoS parameters.

In this embodiment of the present application, each second rule may be a correspondence between a set of QoS parameters and at least one application ID (i.e., a set of QoS parameters may correspond to a plurality of addresses), or may be a correspondence between a plurality of sets of QoS parameters and a plurality of application IDs.

In the embodiment of the present application, there may be a plurality of second rules, for example, the second rule 1 indicates a correspondence between an ID of a chat application and QoS parameters, the second rule 2 indicates a correspondence between an ID of a game application and QoS parameters, and so on.

Optionally, in some embodiments, the determining, by the terminal device, the QoS parameter corresponding to the first application based on the ID of the first application and at least one second rule includes: and under the condition that the QoS parameter corresponding to the first data is not determined based on the address of the first server and at least one first rule, or under the condition that the application layer does not provide the address of the first server, the first terminal equipment determines the QoS parameter corresponding to the first application based on the ID of the first application and at least one second rule.

In this embodiment of the present application, in a case where the first terminal device does not determine the QoS parameter corresponding to the first data according to the address of the first server, the QoS parameter corresponding to the first application may be determined based on the ID of the first application and at least one second rule. The first terminal device does not determine the QoS parameter corresponding to the first data according to the address of the first server, which may be that the application layer provides the address of the first server and the first terminal device fails to determine the QoS parameter corresponding to the first data according to the address of the first server, or that the application layer does not provide the address of the first server, which results in the first terminal device failing to determine the QoS parameter corresponding to the first data.

The second rule in the embodiment of the present application may be a rule preset in the system, so that when the first terminal device cannot determine the QoS parameter according to the address of the server, the determination may be based on the second rule.

Optionally, in some embodiments, as shown in fig. 5, the wireless communication method 200 may further include step 240. Wherein this step 240 may be performed before step 220, in particular before step 230, between

steps

230 and 210, or between

steps

210 and 220.

240, determining the sequence of the first data in the data to be sent based on the priority of the group corresponding to the first data.

In this embodiment of the present application, when the first terminal device needs to send multiple data to be sent, the first terminal device may determine, according to the priority of the group corresponding to the first data, the order of the first data in the data to be sent.

Alternatively, the group to which the data corresponds may refer to a group to which the transmitting terminal device and the receiving terminal device of the data belong in common.

For example, the first terminal device may belong to multiple groups at the same time, for example, may belong to group 1, group 2 and group 3, and the priority orders of the 3 groups are sequentially reduced, that is, the priority of group 1 > the priority of group 2 > the priority of group 3. For example, the transmission order of the data of the receiving end terminal device belonging to the group 1 is earlier than the transmission order of the data of the receiving end terminal device belonging to the group 2.

The priority of the group in the embodiment of the application may be determined by the PCF according to information provided by an application function, where the priority of the group may be filtered along with a packet, qoS parameters, and an application range of QoS rules are stored in a UE policy container, and the PCF sends the container and an ID of the UE to the AMF; the priority of the group in the embodiment of the application may also be determined by the PCF according to the service information, and the priority of the group may be included in the session establishment response sent by the PCF to the SMF along with policy charging control (Policy Charging Control, PCC) rules.

Optionally, in some embodiments, as shown in fig. 6, a wireless communication method 600 may include steps 610-620.

The network device issues 610 information to the terminal device, said information comprising at least one first rule for PC5 interface communication.

For example, if at least one first rule includes 5 first rules, information including the 5 first rules is carried in a PDU Session Establishment Accept message, where the message may include first indication information, and the first indication information may include 5 second indication information, where the 5 second indication information may indicate whether each of the 5 first rules can be used to indicate communication of the PC5 interface. Wherein it is possible that all of the 5 first rules are available for communication of the PC5 interface, it is also possible that 3 of the 5 first rules are available for communication of the PC5 interface, and the remaining 2 first rules are not available for communication of the PC5 interface.

Wherein it is possible that all of the 5 second rules are available for communication of the PC5 interface, it is also possible that 3 of the 5 second rules are available for communication of the PC5 interface, and the remaining 2 second rules are not available for communication of the PC5 interface.

In the method for wireless communication provided by the embodiment of the application, for the session established by the NCIS service, the QoS parameters are determined according to the server addresses of different applications or the IDs of different applications, and then the data communication between the terminal devices is realized according to the determined QoS parameters, so that the quality of the data communication can be ensured.

As shown in fig. 7, a schematic flow chart of a wireless communication method of 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 requesting registration in the network, the request message carrying capability to support NCIS services, and a wireless communication technology (Radio Access Technology, RAT) supported by the PC5 interface, where the wireless communication technology may be LTE and/or NR.

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

703, the amf sends a registration success message to the UE, informing the UE that the registration is successful. Step 702 may also be performed after 703.

And 704, the PCF requests subscription information of the UE from the UDM, wherein the subscription information comprises the ID of the UE.

705, if the UE has NCIS service capability and the subscription allows the UE to use the NCIS service, the PCF determines QoS rules for the PC5 interface based on the information contained in the application function.

The information in the application function may include: for PC5 information indication (indicating whether other parameters are only used for the PC5 interface), group information, UE information, qoS requirements and application server address or application id+server address (or may be a parameter capable of differentiating QoS, it may be enough to determine QoS when filtering data in a subsequent step) where the QoS requirements and application server address or application id+server address correspondence may also be for multiplexing Uu interfaces.

Using the information provided above, the PCF writes the destination address in packet filtering (packet filter) in QoS rules of the PC5 interface as the address of a server, which may be a server address that does not include an application ID or information that is an application id+other servers for distinguishing the server from the application; the QoS requirements are translated into QoS parameters, which may be included in the QoS rules of the PC5 interface or may be separate parameters.

In this embodiment of the present application, when the server addresses are not the same in different applications, the destination address in the packet filtering in the QoS rule of the PC5 interface may be written as the address of the server, where the address of the server may be the address of the server that does not include the application ID. When having the same server address under different applications, the destination address in the packet filtering in the QoS rules of the PC5 interface may be written as the address of the server, which may be the application id+information for distinguishing the server from other servers of the application.

Of course, in some cases, the system may also set default QoS rules that indicate the correspondence of the applied ID settings to QoS parameters.

In this embodiment of the present application, when under different operating systems, there is no application ID that is the same, the destination address in the packet filtering in the QoS rule of the PC5 interface may be written as the application ID, and the application ID may be an application ID that does not include the operating system ID. When under different operating systems, having the same application ID, the destination address in packet filtering in QoS rules of the PC5 interface may be written as an application ID, which may be an operating system id+information for distinguishing the application from other applications of the operating system.

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

After determining the rule, the PCF filters the determined packet, stores the QoS parameters and the usage range of the QoS rule in a 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 NAS transport of DL.

As shown in fig. 8, another schematic flow chart diagram of a wireless communication method of 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, where the request message includes a session ID, an NCIS indication, and a group ID, where the NCIS indication indicates that the session is for an NCIS service, and the expression may be a data network name (Data Network Name, DNN) for NCIS and/or Single network slice selection assistance information (Single-Network Slice Selection Auxiliary Information, S-nsai), and the group ID is an NCIS group ID to which the UE belongs.

802, the smf sends a session setup request message to the PCF, including an indication of the UE's ID, session ID, group ID, NCIS.

803, the pcf generates a PCC rule for the Uu interface, and determines, according to the service information, for example, the NCIS indication, the AF provided information, the PC5 information indication, whether the PC5 interface is available, the group information, the UE information, the QoS requirement and the server address (or may be a parameter capable of differentiating QoS, where the QoS may be determined when the data is filtered by applying the provided parameter in a subsequent step), whether the QoS related parameter in the PCC rule is available for the PC5 interface, and if so, adding the PC5 indication in the PCC rule to indicate that the PC5 interface is available. Wherein the server address mentioned here may be a server address excluding the application ID or an application id+information for distinguishing the server from other servers of the application.

Of course, in some cases, the system may also set a default QoS rule, that is, a correspondence between an application ID and a QoS parameter, where the application ID may be an application ID that does not include an operating system ID or an operating system id+information for distinguishing the application from other applications of the operating system.

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

The PCF sends a session establishment response to the SMF, which may contain PCC rules, qoS usage ranges.

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

The above procedure illustrates the determination of the QoS rule of the PC5 interface in the NCIS service, and how the UE uses the determined QoS rule to perform data transmission will be described as shown in fig. 9, which is a schematic diagram of the UE performing data transmission through the PC5 interface using the NCIS service. As shown in fig. 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 PC5 to the PC5 layer.

902, when an application in the UE needs to transmit data, the application determines that the data needs to be transmitted by using a PC5 interface, invokes an application program interface (Application Programming Interface, API) of the PC5 interface, and provides data, where the server address corresponds to a server address, where the server address may be an address of a server that does not include an application ID or information that is an application id+distinguishes the server from a server of the application.

903, the operating system includes the applied data in a PDU (network protocol (Internet Protocol, IP) or ethernet), a destination address and port number in the header of the PDU.

If unicast, the PDU includes the address port number of the opposite terminal UE; in case of multicast, the PDU includes an address port number corresponding to the group.

The operating system sends the packed PDU and the server address corresponding to the data to the PC5 layer, which may be, for example, a D2D layer, a V2X layer, an NCIS layer, etc. .

904, the PC5 layer uses packet filtering on the PDUs to determine the corresponding QoS flows, using the server address AS destination address and port number when matching instead of using the address port number in the header, and the PC5 sends the data, the ID of the quality of service Flow (QoS Flow ID, QFI) to the Access Stratum (AS) after determining the QoS flows.
