Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

First, terms referred to in the embodiments of the present application are briefly described:

5G network system architecture:

referring to fig. 1 in combination, the 5G network system includes: user Equipment (3 GPP naming of mobile terminal) (User Equipment, UE), (radio) access Network ((R) AN), user Plane Function (UPF), data Network (DN), and control Plane Function.

Wherein the control plane functions include: access and Mobility Management Function (AMF), session Management Function (SMF), policy Control Function (PCF), and Unified Data Manager (UDM), application Function (AF), network Slice Selection Function (NSSF), authentication service Function (AUSF).

The UE is connected with the AN through a Uu air interface, exchanges Access layer information and performs wireless data transmission, and is connected with the AMF through AN N1 interface and a Non Access Stratum (NAS) and exchanges NAS information. The AMF is a mobility management function in the core network, the SMF is a session management function in the core network, and the AMF is also responsible for forwarding the slave session management related messages between the UE and the SMF besides carrying out mobility management on the UE. The PCF is a policy management function in the core network, and is responsible for formulating policies related to mobility management, session management, charging, and the like for the UE. The UPF is a user plane function in the core network, and performs data transmission with AN external data network through AN N6 interface and performs data transmission with the AN through AN N3 interface.

And after the UE accesses the 5G network through the Uu port, the service data is transmitted through the network. When service is initiated, a network layer of the UE obtains a QoS requirement of the service from an upper layer (e.g., an operating system or an application), the UE converts the QoS requirement of the service into a QoS parameter of a Uu interface, for example, 5QI, and sends the QoS parameter to a network, and a Protocol Data Unit (PDU) session is established under the control of the SMF for Data transmission. The 5QI may be mapped to a range of QoS characteristics such as delay, error rate, priority, etc.

In the network architecture shown in fig. 1, the terminal device and the operator network directly communicate over the Uu air interface.

PC5 unicast link:

proximity-based Services (ProSe) refers to a scheme for supporting communication between devices whose physical addresses are close to each other. In particular, the purpose of Prose is to discover nearby application operating devices and ultimately support application-related data exchange. For example, proSe can be considered as applied to applications such as Social Networking Services (SNS), commerce, and games.

ProSe may also be referred to as Device to Device (D2D) communication. That is, proSe refers to a communication scheme for establishing a direct link between a plurality of terminal devices, thereby directly exchanging user data (e.g., audio, multimedia data, etc.) between the terminal devices without going through a network. The ProSe communication may include UE-to-UE communication, peer-to-Peer (P2P) communication, and so on. In addition, proSe Communication can be applied to Machine (M2M) Communication, machine Type Communication (MTC), and the like. Thus, proSe is seen as a solution to reduce the base station burden due to the rapid increase in data traffic. In addition to this, by employing ProSe, effects such as reduction of procedures of a base station, reduction of power consumption of devices participating in ProSe, improvement of data transmission speed, increase of network capacity, load distribution, enlargement of cell coverage, and the like can be expected.

The ProSe capable terminal device can communicate directly with another ProSe capable terminal device over a PC5 unicast link, i.e. a PC5 interface. The two terminal devices respectively determine the QoS requirement corresponding to the service data transmission according to the QoS requirement of the service, and PC5QoS data streams capable of guaranteeing the corresponding QoS requirement are established between the two terminal devices for service data transmission, so that the service quality of the communication of the service in the PC5 is guaranteed. The QoS parameters of the PC5QoS data flow include PQI, which can be mapped to a range of QoS characteristics such as delay, error rate, priority, etc.

As shown in fig. 2, two terminal apparatuses perform near field communication. UE1 and UE2 are in direct communication through PC5 unicast link, and PC5QoS data stream #1, PC5QoS data stream #2 and PC5QoS data stream #3 are established between two terminal devices for transmitting service data.

When a terminal device has both the capability of connecting to an external data network through a 5G network and the ProSe capability, the terminal device may serve as a relay terminal (relay UE), and another Remote terminal (Remote UE) having the ProSe capability may establish a direct connection with the relay UE through a PC5 interface and interact with the external network through a PDU session established by the relay UE and the 5G network.

As shown in fig. 3, the terminal device accesses the operator network through the relay terminal. The Remote UE accesses the wireless access network through the Relay UE.

When two terminal devices with ProSe capability are far away and cannot establish communication directly through a PC5 interface, communication transfer can be carried out through a Relay UE with ProSe capability.

As shown in fig. 4, one terminal apparatus performs near field communication with another terminal apparatus through a relay terminal. The relay UE can directly communicate with the UE1 through the PC5 interface, and can also directly communicate with the UE2 through the PC5 interface, so that the UE1 and the UE2 can perform service interaction through the relay UE.

Fig. 5 is a block diagram illustrating a communication system provided by an exemplary embodiment of the present application, which may include: a network device 12 and a first terminal 14, a second terminal 16 and a relay terminal 18.

The access network includes a number of network devices 12. Network device 12 may be a base station, which is a device deployed in an access network to provide wireless communication functions for terminals. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ, for example in LTE systems, referred to as eNodeB or eNB; in a 5G NR-U system, it is called gNodeB or gNB. The description of "base station" may change as communication technology evolves. For convenience of this embodiment, the above-mentioned apparatuses for providing a terminal device (at least one of the first terminal 14, the second terminal 16 and the relay terminal 18) with a wireless communication function are collectively referred to as a network device.

The first terminal 14, the second terminal 16, and the relay terminal 18 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of user equipment, mobile Stations (MSs), terminals (terminal devices), and so forth.

The network device 12 and the first terminal 14 may communicate with each other via some air interface technology, such as a Uu interface. The network device 12 can communicate with the first terminal 14 through the relay terminal 18, the relay terminal 18 and the first terminal 14 are connected through a PC5 interface, and the network device 12 and the relay terminal 18 communicate with each other through a Uu interface. The first terminal 14 can communicate with the second terminal 16 through the relay terminal 18, and the relay terminal 18 is in a PC5 interface with the first terminal 14, and the second terminal 16 is in a PC5 interface with the relay terminal 18.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: global System for Mobile Communication (GSM) System, code Division Multiple Access (CDMA) System, wideband Code Division Multiple Access (WCDMA) System, general Packet Radio Service (GPRS), long Term Evolution (Long Term Evolution, LTE) System, LTE Frequency Division Duplex (FDD) System, LTE Time Division Duplex (TDD) System, advanced Long Term Evolution (Advanced Long Term Evolution, an LTE-a) System, a New Radio (NR) System, an Evolution System of the NR System, an LTE (LTE-based Access to Unlicensed spectrum) System on an Unlicensed Frequency band, an NR-U System, a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) Communication System, a Wireless Local Area Network (WLAN), a Wireless Fidelity (WiFi), a next generation Communication System, or other Communication systems.

Generally, the conventional Communication system supports a limited number of connections and is easy to implement, however, with the development of Communication technology, the mobile Communication system will support not only conventional Communication but also, for example, device-to-Device (D2D) Communication, machine-to-Machine (M2M) Communication, machine Type Communication (MTC), vehicle-to-Vehicle (V2V) Communication, and Vehicle networking (V2X) system, etc. The embodiments of the present application can also be applied to these communication systems.

The technical scheme 1:

fig. 6 is a flowchart illustrating a QoS parameter setting method according to an exemplary embodiment of the present application. The method can be applied to a communication system as shown in fig. 5, and comprises the following steps:

step 610, the first network device sends configuration information to the first terminal, where the configuration information includes: and the first information comprises access scene information.

The first QoS information is QoS information between the first terminal and the opposite terminal, which is determined by the first terminal for the service to be transmitted. Optionally, in an access scenario in which the first terminal completes communication with another communication device through the relay terminal, the peer device is the relay terminal, and the first QoS information is QoS information between the first terminal and the relay terminal.

Alternatively, the first QoS information may need to correspond to QoS information between the first terminal and a destination of the communication. Such as: when the parameter in the QoS information is a delay, the delay corresponding to the first QoS information is less than a delay that needs to be guaranteed between the first terminal and a destination of the communication (when the first terminal implements the destination of the communication through the relay terminal); or, the delay corresponding to the first QoS information is equal to the delay that needs to be guaranteed between the first terminal and the destination of the communication (in the case that the first terminal directly communicates with the destination of the communication).

The first information is information having a correspondence relationship with the first QoS information. In a possible implementation manner, the first information includes access scenario information, and the access scenario information is used to indicate an access scenario of the first terminal. That is, the correspondence between the access scenario information and the first QoS information is dynamically configured by the first network device. Optionally, the access scenario includes: an access scenario in which a first terminal directly communicates with another communication device; or an access scenario in which the first terminal communicates with another communication device through the relay terminal.

Optionally, the different access scenario information corresponds to different first QoS information. Such as: when the access scenario information is access scenario information 1), the first QoS information is: the time delay is A seconds; when the access scenario information is access scenario information 2), the first QoS information is: the time delay is B seconds; the values of A and B are different.

Step 620, the first terminal determines the first QoS information corresponding to the service according to the corresponding relationship.

Wherein, the corresponding relation includes: the first information comprises access scene information, and the access scene information is used for indicating an access scene of the first terminal.

In one implementation, the correspondence is determined based on configuration information from the first network device, as shown in step 610. In another implementation, the correspondence is predefined in a standard.

When the first terminal needs to determine corresponding QoS information (namely first QoS information) for a service to be transmitted, access scene information corresponding to the current service is determined according to an access scene of the first terminal, and then the first QoS information corresponding to the access scene information is searched according to the obtained corresponding relation.

Step 630, the first terminal sends the first QoS information to the peer device.

The opposite terminal device is a device that directly communicates with the first terminal. Optionally, in an access scenario in which the first terminal completes communication with another communication device through the relay terminal, the peer device is the relay terminal.

The first QoS information is used to set QoS parameters between the first terminal and the peer device. Optionally, the first terminal sends the first QoS information to the peer device, and requests the peer device to perform QoS parameter setting between the first terminal and the peer device according to the first QoS information. Optionally, the first terminal performs QoS parameter setting between the first terminal and the peer device by sending the first QoS information to the peer device.

In summary, in the method provided by this embodiment, when determining the first QoS information corresponding to the service to be transmitted, the first terminal may determine, according to the correspondence between the pre-obtained access scenario information and the first QoS information, the corresponding first QoS information according to different access scenarios, and send the first QoS information to the peer device in the access scenario, so that when the first terminal accesses another communication device through the relay terminal, the relay terminal may obtain the first QoS information corresponding to the access scenario, where the first QoS information is used to set QoS parameters between the first terminal and the relay terminal, thereby avoiding a problem that, in an access scenario of this type, an actual transmission quality of the service cannot meet a transmission quality required by the service because the first terminal directly sends the QoS information between the first terminal corresponding to the service and a destination end of communication to the relay terminal.

The embodiment of the present application does not limit the specific implementation form of the network element of the network function for near field communication management.

The access scene information is used for indicating an access scene of the first terminal.

The first network device may be implemented as a PCF network element or a network element for network functions of near field communication management, which enables sending the configuration information to the first terminal by performing step 711 or step 712. Illustratively, the network element of the network function for near field communication management performs user plane interaction with the first terminal and sends configuration information to the first terminal. Illustratively, the PCF network element performs control plane interaction with the first terminal, the PCF network element sends the configuration information to the AMF network element, and the AMF includes the configuration information in the NAS message and sends the NAS message to the first terminal.

Optionally, the first QoS information includes, but is not limited to: at least one of 5G service quality identification (5GQoSIDications, 5QI), PC 5G service quality identification (PC 5G QoS indications, PQI), priority, bandwidth, time delay and error rate.

Wherein, 5QI is a QoS identifier introduced for a 5G network architecture, and 5QI may be mapped as: time delay, error rate, bandwidth and other parameters. The PQI is a QoS identifier introduced for near field communication between a terminal device and another terminal device, and may be mapped as: time delay, error rate, bandwidth and other parameters.

Step 720, the first terminal determines the first QoS information corresponding to the service according to the corresponding relationship.

In one implementation, the correspondence is determined based on configuration information from the first network device, as shown in steps 711 and 712. In another implementation, the correspondence is predefined in a standard.

Wherein, the corresponding relation includes: a correspondence between the first information and the first QoS information. The first information is information having a correspondence relationship with the first QoS information.

In a possible implementation manner, the first information includes access scenario information, and the access scenario information is used to indicate an access scenario of the first terminal. The access scenario information includes at least one of:

1) A first terminal directly accesses to an operator network;

2) The first terminal and the second terminal carry out near field communication;

3) A first terminal accesses to an operator network through a first relay terminal;

4) The first terminal performs near field communication with the second terminal through the second relay terminal.

When the access scenario information is 1), corresponding to fig. 1, the air interface between the first terminal and the operator network is a Uu interface; when the access scenario information is 2), corresponding to fig. 2, both the first terminal and the second terminal are terminal devices with ProSe capability, and an air interface between the first terminal and the second terminal is a PC5 interface; when the access scenario information is 3), corresponding to fig. 3, the first terminal and the first relay terminal are both terminal devices with ProSe capability, an air interface between the first terminal and the first relay terminal is a PC5 interface, and an air interface between the first relay terminal and the operator network is a Uu interface; access scenario information is 4), corresponding to fig. 4, the first terminal, the second relay terminal, and the second terminal are all terminal devices with ProSe capability, an air interface between the first terminal and the second relay terminal is a PC5 interface, and an air interface between the second relay terminal and the second terminal is also a PC5 interface.

In another possible implementation manner, the first information includes access scenario information and service description information. The service description information is used for identifying a service; the service description information includes but is not limited to: at least one of an application identifier, an application type, a service identifier, a service type, a service code, an Internet Protocol (IP) triplet, an IP quintet, a service capability description, and a domain name.

Illustratively, reference is made in combination to the following table one:

The correspondence is a correspondence between first information including access scenario information and service description information, and the first QoS information. The first terminal can determine the first QoS information corresponding to the service by looking up the corresponding relationship shown in the table one.

The access scene information corresponding to the service comprises: and under the condition that the first terminal is directly accessed to the operator network, the opposite terminal equipment is an SMF network element.

The access scene information corresponding to the service includes: and under the condition that the first terminal and the second terminal carry out near field communication, the opposite terminal equipment is the second terminal.

The access scene information corresponding to the service includes: and under the condition that the first terminal is accessed to the operator network through the first relay terminal, the opposite terminal equipment is the first relay terminal. Optionally, upon receiving the first QoS information, the first relay terminal will determine QoS requirements corresponding to the traffic between the first relay terminal and a data network communicating through the operator network.

The access scene information corresponding to the service includes: and under the condition that the first terminal is accessed to the second terminal through the second relay terminal, the opposite terminal equipment is the second relay terminal. Optionally, after receiving the first QoS information, the second relay terminal determines a QoS requirement corresponding to the service between the second relay terminal and the second terminal.

In summary, in the method provided in this embodiment, the corresponding relationship may be predefined in the standard, or the configuration information is from the configuration information sent by the first network device, where the configuration information is from a PCF network element or a network element with a network function for short-range communication management, so that the first terminal may obtain the corresponding relationship in different ways, thereby improving flexibility of the configuration of the corresponding relationship.

Next, the above-described technical means 2 will be explained as an example. In this embodiment, the QoS information includes, but is not limited to: time delay, error rate, bandwidth and other parameters.

step 1010, the terminal device sends the second QoS information and the third QoS information to the relay terminal.

A terminal device (for Remote UE) determines an end-to-end QoS requirement of an initiated service according to an application trigger, and the terminal device splits QoS information corresponding to the end-to-end QoS requirement into second QoS information (corresponding to the QoS requirement from the terminal device to a relay terminal) and third QoS information (corresponding to the QoS requirement from the relay terminal to the data network through an operator network), for example, 100ms of delay is split into 10ms of delay from the terminal device to the relay terminal, and 90ms of delay from the relay terminal to the data network through the operator network.

The terminal device initiates the establishment or modification of the PC5 connection to the relay terminal, including the QoS requirements from the terminal device to the relay terminal (i.e. the second QoS information) and the QoS requirements corresponding to the communication of the relay terminal with the data network through the operator network (i.e. the third QoS information).

Specific parameters in the second QoS information include, but are not limited to, PQI values. For example, if the following PQI mapping relationship is defined, the terminal device may provide a PQI =90 delay requirement representing 10ms, but of course, the specific parameter may not be the PQI, but may be a direct delay requirement of 10ms or other parameters that can be mapped, and the second QoS information is used for setting the QoS parameter between the terminal device and the relay terminal. As shown in table six:

watch six

PQI value	Priority level	Time delay	Error rate
90	2	10ms	10 ^-4

Specific parameters in the third QoS information include, but are not limited to, a 5QI value. For example, if the following 5QI mapping relationship is defined, the terminal device may provide a delay requirement that 5QI =45 represents 90ms, and of course, the specific parameter may not be 5QI, but may be a requirement that the direct delay is 90ms or other parameters that can be mapped. The third QoS information is used for the relay terminal to request the network device for QoS parameter setting corresponding to communication between the relay terminal and the data network through the operator network. As shown in table seven:

watch seven

5QI value	Priority level	Time delay	Error rate
45	2	90ms	10 ^-4

Optionally, the terminal device further sends service description information corresponding to the service to the relay terminal, where the service description information is not limited to the information that can be used to describe the specific service, such as the application identifier, the application type, the service identifier, the service type, the service code, the IP triplet, the IP quintet, the service capability description, and the domain name.

And step 1020, the relay terminal sends the third QoS information to the SMF network element.

And the relay terminal initiates the establishment or modification of the PDU conversation to the 5G network according to the received QoS information. The request message sent by the relay terminal to the SMF network element includes the third QoS information received from the terminal device, for example, 5QI information 5QI =45, or a request with a delay of 90ms.

Optionally, the relay terminal further sends service description information corresponding to the service to the SMF network element.

In step 1030, the smf element feeds back the third QoS parameter.

And the SMF network element determines a third QoS parameter corresponding to the communication between the relay terminal and the data network through the operator network according to the request received from the relay terminal, and sends the third QoS parameter to the relay terminal through the establishment or modification flow of the PDU session.

Step 1040, the relay terminal feeds back the second QoS parameter.

The relay terminal determines a second QoS parameter for controlling the terminal device to the relay terminal, and transmits the second QoS parameter to the terminal device through the establishment or modification flow of the PC5 connection.

It is understood that the above step 1040 may be performed before steps 1020 and 1030.
