[0202] In order to better understand the solution of the embodiment of the present application, the following contents are first described:

[0203] (1) 5G ProSe UE-to-Network Relay Infrastructure

[0204] Figure 1aThe figure shows the 5G ProSe UE-to-Network Relay infrastructure. When the UE is out of network coverage or the Uu interface signal quality is poor, it cannot connect to the network directly. It can connect to the network through a UE with relay function. The former is called Remote UE and the latter is called Relay UE. The Relay UE registers with the network, establishes a Protocol Data Unit (PDU) session and QoS flow to communicate with the network. The Remote UE communicates with the Relay UE through the PC5 interface (the communication interface between UEs), and forwards data through the PDU session and QoS flow of the Relay UE to achieve the purpose of communicating with the network.

[0205] (2) UE-to-Network Relay Architecture Based on N3IWF

[0206] exist Figure 1a Based on the UE-to-Network Relay infrastructure shown in the figure, in order to ensure end-to-end security, a UE-to-Network Relay architecture based on non-3GPP network functions (Non-3GPP InterWorking Function, N3IWF) was proposed in the research of the 5GProSe project.

[0207] Figure 1b The figure shows the UE-to-Network Relay architecture based on N3WIF. In this architecture, the Relay UE is still registered with the network, and establishes PDU sessions and QoS flows to achieve communication with the network. Unlike Figure 1, the PDU session of the Relay UE needs to support the connection to the N3IWF. The Remote UE establishes an IPSec connection with the N3IWF through the PDU session of the Relay UE, and the Remote UE sends NAS signaling messages and user plane data to the network through the IPSec connection.

[0208] (3) Connection establishment process based on N3IWF UE-to-Network Relay architecture

[0209] like Figure 1c As shown, the specific process is as follows:

[0210] 1. The Remote UE and Relay UE initiate a registration process and obtain ProSe policy and URSP policy information from the network. The policy information indicates whether the Remote UE accesses the 5GC through the N3IWF.

[0211] 2. The Remote UE performs a discovery process to discover the UE-to-Network Relay.

[0212] 3. The Remote UE selects the UE-to-Network Relay and establishes direct one-to-one communication. The communication interface between the Remote UE and the Relay UE is the PC5 interface. If a new PDU session needs to be created, the UE-to-Network Relay initiates a new PDU session establishment process.

[0213] 4. UE-to-Network Relay assigns an IP address to the Remote UE.

[0214] 5. The Remote UE selects N3IWF and determines the N3IWF IP address.

[0215] 6. The Remote UE uses the IKE process to establish an IPSec connection with the N3IWF and initiates the Non-access stratum (NAS) registration process. After the IPSec connection is established, the Remote UE can establish a PDU session and QoS flow with the network through NAS messages.

[0216] In the UE-to-Network Relay architecture based on N3IWF, the Remote UE establishes a PDU session and QoS flow with the network through NAS messages, and the PDU session and QoS flow are carried on the PDU session and QoS flow of the Relay UE. Figure 1d As shown, the transmission of the PDU transmitted between the Remote UE and the Remote UE UPF between the Remote UE and the N3IWF is carried on the PC5 connection (and PC5 QoS flow) between the Remote UE and the Relay UE and the PDU session (and Uu QoS flow) between the Relay UE and the Relay UEUPF. To meet the QoS requirements (such as latency, bit rate, etc.) of the QoS flow between the Remote UE and the Remote UE UPF, the PC5 QoS flow and Uu QoS flow of the Relay UE must also be able to meet the corresponding QoS requirements.

[0217] The prior art has not yet solved the problem of how to control the PC5 QoS flow between the Remote UE and the Relay UE and the QoS flow between the Relay UE and the Relay UE UPF to meet the QoS requirement of the QoS flow between the Remote UE and the Remote UE UPF.

[0218] See also Figure 2 , an embodiment of the present application provides a QoS control method, applied to a Remote UE, the method comprising:

[0219] Step 201: Determine PC5 QoS parameters and Packet Filter;

[0220] Step 202: Send PC5 QoS parameters and Packet Filter to Relay UE.

[0221] In an embodiment of the present application, the QoS establishment process is initiated by the Remote UE. Specifically, the Remote UE determines the PC5 interface quality of service (PC5 QoS) parameters and packet filter (Packet Filter), and sends the determined PC5 QoS parameters and Packet Filter to the Relay UE, so that the Relay UE can determine the target QoS parameters and target Packet Filter based on the PC5 QoS parameters and Packet Filter, and complete the establishment of the PC5 QoS flow between the Remote UE and the Relay UE and the QoS flow between the Relay UE and the Relay UE UPF, thereby meeting the QoS requirements of the QoS flow between the Remote UE and the Remote UE UPF.

[0222] In some implementations, the Packet Filter includes a non-3GPP InterWorking Function (N3IWF) IP address and a Security Parameter Index (SPI), where the Relay UE obtains the SPI from the N3IWF.

[0223] Furthermore, the method further includes: mapping the uplink data packet to the PC5 QoS flow according to the Packet Filter.

[0224] It is understandable that the above-mentioned Packet Filter can also be called Relay UE Packet Filter; at the same time, optionally, the Remote UE can also determine the Remote UE PC5 QoS rule (Rule) and the Uu interface service quality (Uu QoS) parameter, and the Uu QoS parameter can also be called Relay UE QoS parameter.

[0225] In some implementations, the sending of PC5 QoS parameters and Packet Filter to the Relay UE specifically includes: sending a first request message for establishing a new PC5 QoS flow to the Relay UE, the first request message including the PC5 QoS parameters and Packet Filter. Optionally, the first request message may be called a Link Modification Request message, which carries the PC5 QoS parameters and Packet Filter.

[0226] In some implementations, the above-mentioned determining PC5 QoS parameters specifically includes: determining PC5 QoS parameters according to the QoS parameters received from N3IWF and a mapping relationship between Uu QoS parameters and PC5 QoS parameters.

[0227] In an embodiment of the present application, the N3IWF sends the Uu QoS parameters to the Remote UE in advance. Specifically, the N3IWF may send the Uu QoS parameters to the Remote UE via a PDU session establishment accept message, and the message may also include a QoSRule.

[0228] Furthermore, the method further includes: receiving first QoS policy information from a policy control function (PCF), wherein the first QoS policy information includes a mapping relationship between Uu QoS parameters and PC5 QoS parameters.

[0229] In an embodiment of the present application, the mapping relationship between the Uu QoS parameters and the PC5 QoS parameters is obtained by the Remote UE by receiving the first QoS policy information from the PCF. In some implementations, the Remote UE can receive the first QoS policy information from the PCF through an access and mobility management function (Access Control And Mobility Management Function, AMF).

[0230] In an embodiment of the present application, after the Remote UE determines the PC5 QoS parameters and Packet Filter, it sends the determined PC5 QoS parameters and Packet Filter to the RelayUE, establishes a PC5 QoS flow between the Remote UE and the Relay UE, and a QoS flow between the Relay UE and the Relay UE UPF, so as to meet the QoS requirements of the QoS flow between the Remote UE and the Remote UE UPF.

[0231] See also Figure 3The embodiment of the present application provides a QoS control method, which is applied to a Relay UE session management function (Session Management Function, SMF), and the method includes:

[0234] In the embodiment of the present application, sending Uu QoS parameters and Uu QoS Rules to the Relay UE specifically includes: sending a PDU session request message to the Relay UE, where the PDU session request message includes the Uu QoS parameters and Uu QoS Rules.

[0235] The above determination of Uu QoS parameters and Uu QoS Rules specifically includes two cases: the QoS flow establishment process is initiated by the Remote UE, and the QoS flow establishment process is initiated by the Relay UE SMF.

[0236] For the case where the QoS flow establishment process is initiated by the Remote UE:

[0237] The above-mentioned determining of the Uu QoS parameter includes: receiving a first target QoS parameter from the Relay UE, where the first target QoS parameter is determined by the Relay UE; and determining the Uu QoS parameter according to the first target QoS parameter.

[0238] In the embodiment of the present application, the Relay UE SMF determines the Uu QoS parameter specifically based on the first target QoS parameter provided by the Relay UE, and the first target QoS parameter is determined by the Relay UE based on the PC5 QoS parameter received from the Remote UE.

[0239] The above-mentioned determination of the Uu QoS Rule includes: receiving a first target Packet Filter from the Relay UE, where the first target Packet Filter is determined by the Relay UE; and determining the Uu QoS Rule according to the first target Packet Filter, where the Uu QoS Rule includes a QoS flow identifier (QFI) and the first target Packet Filter.

[0241] In some implementations, the method further includes: sending a first target Packet Filter to a Relay UE user plane management function (User Plane Function, UPF), so that the Relay UE UPF maps the downlink IP packet to the corresponding QoS flow according to the first target Packet Filter. Specifically, the Relay UE SMF may send an N4 session request message to the Relay UE UPF, the message including the first target Packet Filter, and the UPF uses the first target Packet Filter to map the downlink IP packet to the corresponding QoS flow.

[0242] For the case where the QoS flow establishment process is initiated by the Relay UE SMF:

[0243] The above-mentioned determination of the Uu QoS parameters includes: determining the Uu QoS parameters according to a mapping relationship between a Differentiated Services Code Point (DSCP) and the QoS parameters and a DSCP value in a downstream IP packet sent by the N3IWF.

[0244] In the embodiment of the present application, the Relay UE SMF itself determines the Uu QoS parameters, specifically based on the mapping relationship between DSCP and QoS parameters and the DSCP value in the downlink IP packet sent by the N3IWF.

[0245] The determining of the Uu QoS Rule includes: determining the Uu QoS Rule according to the QFI and the Packet Filter.

[0247] In the embodiment of the present application, the QoS flow establishment process is initiated by the Remote UE or the Relay UE SMF. After the RelayUE SMF determines the Uu QoS parameters and the Uu QoS Rule, the determined Uu QoS parameters and the Uu QoS Rule are sent to the Relay UE to establish the PC5 QoS flow between the Remote UE and the Relay UE and the QoS flow between the Relay UE and the Relay UE UPF to meet the QoS requirements of the QoS flow between the Remote UE and the Remote UE UPF.
