Embodiments of the present application describe various embodiments in connection with a terminal device and a network device, wherein: a terminal device can also be called a user equipment, access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, user device, or the like. The terminal device may be a Station (ST) in a WLAN, may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA) device, a handheld device with wireless communication functionality, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device, and a next generation communication system, such as a terminal device in an NR network or a terminal device in a future evolved public land mobile network (Public Land Mobile Network, PLMN) network, etc.

By way of example, and not limitation, in embodiments of the present application, the terminal device may also be a wearable device. The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wear by applying wearable technology and developing wearable devices, such as glasses, gloves, watches, clothes, shoes and the like. The wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also can realize a powerful function through software support, data interaction and cloud interaction. The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.

The AN device 102 may be a device for communicating with a mobile device, where the AN device 102 may be AN Access Point (AP) in a WLAN, a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, AN evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, a relay station or AN Access Point, a vehicle device, a wearable device, a base station (gNB) in AN NR network, or a network device in a PLMN network for future evolution, etc.

In the embodiment of the present application, the network device provides services for a cell, and the terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource, or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station), and the cell may belong to a macro base station, or may belong to a base station corresponding to a Small cell (Small cell), where the Small cell may include: urban cells (Metro cells), micro cells (Micro cells), pico cells (Pico cells), femto cells (Femto cells) and the like, and the small cells have the characteristics of small coverage area and low transmitting power and are suitable for providing high-rate data transmission services.

In the embodiment of the application, the terminal equipment with ProSe capability can directly communicate with another terminal equipment with ProSe capability through a PC5 interface. When one terminal device can be connected with an external data network through a 5G network and has ProSe capability, the terminal device can serve as a Relay terminal, and another remote terminal with the ProSe capability can establish direct connection with a Relay UE through a PC5 interface and interact with the external network through PDU session established by the remote terminal with the 5G network. The system architecture is shown in fig. 2. AS shown in fig. 2, the remote terminal is connected to the relay terminal through a PC5 interface, and the relay terminal is connected to the next generation evolved radio access network (Next Generation Evolutional Radio Access Network, NG-RAN) through a Uu interface, thereby connecting to a 5G core network (5G Core Network,5GC), and the 5GC is connected to the application server (application server, AS) through an N6 interface.

Fig. 2 is an illustration of a 5G communication system, but of course, the present invention is not limited to this, and may be applied to other 3GPP communication systems, such as a 4G communication system, or a future 3GPP communication system. In addition, in the embodiment of the present application, the Application Server (AS) in fig. 2 may also be other terminal devices or the external public security internet.

It should be noted that, the relay terminal establishes a PDU session with the 5G network, and the remote terminal performs data interaction with the external network through the PDU session of the relay terminal. The network element serving the relay terminal determines QoS control for the PDU session of the relay terminal according to the subscription information of the relay terminal.

However, the network element serving the relay terminal cannot obtain the subscription information of the remote terminal, and thus cannot perform effective QoS control on data transmission of the remote terminal. For example, assume that the UE-AMBR subscribed by the remote terminal is 100Mbps, that is, when the remote terminal directly performs data interaction with the external network through the 5G network, the sum of the maximum code rates of all non-GBR services at the allowed UE level is 100Mbps, and assume that the UE-AMBR subscribed by the relay terminal is 500Mbps. Because the network element serving the relay terminal cannot obtain the subscription information of the remote terminal, when the remote terminal performs data transmission through the PDU session of the relay terminal, the remote terminal may be capable of transmitting 500Mbps data, which far exceeds the subscription limit of 100Mbps of the remote terminal and the 5G network.

Based on this, when the remote terminal performs data interaction with the external network through the relay terminal, the PCF of the relay terminal, the AMF of the relay terminal, the SMF of the relay terminal and the functions of the relay terminal are further perfected, so as to improve the management and control capability of the network to the remote terminal and the system performance of the relay terminal.

For example, the PCF of the relay terminal may determine the first quality of service QoS control information of the relay terminal by being based on the at least one subscription information.

Therefore, the access network device of the relay terminal or the user plane function UPF of the relay terminal can control the QoS of the relay terminal based on the first QoS control information determined by the PCF, so that the relay terminal can control the data transmission of the remote terminal, and correspondingly, the management and control capability of the network to the remote terminal and the system performance of the relay terminal can be improved.

For example, the PCF of the relay terminal may determine the second quality of service QoS control information of the remote terminal by based on the at least one subscription information.

Therefore, the access network device of the relay terminal, the user plane function UPF of the relay terminal or the relay terminal can control the QoS of the remote terminal based on the second QoS control information determined by the PCF, and accordingly, the management and control capability of the network to the remote terminal and the system performance of the relay terminal can be improved.
