Embodiments of the present invention are described below with reference to the accompanying drawings. The QoS management method and the related equipment provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent lte communication system.

Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network device 12, where the terminal 11 may be a user terminal or other terminal-side devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited, and the terminal may be a terminal-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device). The network device 12 may be any one of a Policy Control Function (PCF), a Session Management Function (SMF), and a base station. When the network device is a base station, the network device may be a 5G base station, or a later-version base station, or a base station in another communication system, or referred to as a node B, an evolved node B, or a Transmission Reception Point (TRP), or an Access Point (AP), or another vocabulary in the field, and the network device is not limited to a specific technical vocabulary as long as the same technical effect is achieved. In addition, the network device 12 may be a Master Node (MN) or a Secondary Node (SN). It should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the network device is not limited. The base station may also be referred to as a Next Generation Radio Access Network (NG-RAN).

Referring to fig. 2, fig. 2 is a flowchart of a QoS management method according to an embodiment of the present invention, where the QoS management method is applied to an SMF, and as shown in fig. 2, the QoS management method includes the following steps:

step 201, sending a QoS rule, a first QoS flow class parameter and a QoS flow class parameter set to a terminal;

step 202, sending a first QoS text and a QoS text set to a base station;

In the embodiment of the present invention, the execution sequence of the step 201 and the step 202 may be set according to actual needs, and is not further limited herein. For example, step 202 may be performed before step 201, may be performed after step 201, or may be performed simultaneously with step 201 and step 202.

It should be understood that specific Network entities on the Network side may include one or more Network entities of a Unified Data Management Function (UDM), a PCF, a Network Exposure Function (NEF), an Application Function (AF), a Unified Data Repository (UDR), an Access and Mobility Management Function (AFM), a User Plane Function (UPF), and a base station, in addition to the SMF.

It should be noted that the QoS flow class parameter set may include one or more candidate second QoS flow class parameters, and since the network side device configures the terminal with one or more candidate second QoS flow class parameters, the terminal may select one QoS flow class parameter to request the network device to dynamically adjust the QoS of the PC5 according to the relationship between the actually measured QoS flow class parameter and the second QoS flow class parameter, so as to implement QoS adjustment on the PC5 interface controlled by the network, and meet the continuity of the traffic on the PC5 interface.

Optionally, in an embodiment, the method further includes:

receiving a target PCC rule sent by a policy control function;

deriving the first QoS flow level parameter, the set of QoS flow level parameters, the QoS rule, the first QoS text and the set of QoS text according to the target PCC rule;

wherein the target PCC rules include a first PCC rule that the policy control function requests service requirement translation according to a PC5 interface provided by an application server, and a second PCC rule that the policy control function translates according to a PC5 interface alternative service requirement provided by the application server, the first PCC rule corresponding to the first QoS flow class parameter and the first QoS text, and the second PCC rule corresponding to the QoS flow class parameter set and the QoS text set.

In the embodiment, in the short-distance discovery mechanism, the terminals can request the establishment of the connection of the PC5 from the application server; or application server triggered PC5 connection establishment. At this time, the application server may determine the service requirement provided to the PCF according to the communication service information corresponding to the PC5 connection setup. For example, in this embodiment, in order to meet the continuity requirement of the communication service on the PC5 interface when the communication service is the NCIS service, the application server may provide the PCF with a request service requirement of the PC5 interface and an alternative service requirement of the PC5 interface, and may instruct the PCF to assist the QoS adjustment on the PC5 interface.

Specifically, after receiving a PC5 interface request service requirement And a PC5 interface candidate service requirement provided by an application server, a PCF may authorize service information of the application server, And then convert the PC5 interface request service requirement provided by the application server into a first PCC rule, where the first PCC rule carries a PC5 interface QoS parameter, And the PC5 interface QoS parameter may include a 5GQoS Identifier (5G QoS Identifier, 5QI), an Allocation And Retention Priority (ARP), And a Guaranteed Bit Rate (GBR) or a maximum Bit Rate (maximum Bit Rate, MBR). Meanwhile, the PCF converts the service requirement for the PC5 interface candidate into a second PCC rule, where the second PCC rule carries the QoS parameter for the PC5 interface candidate. After obtaining the first PCC rule and the second PCC rule, the PCF sends the first PCC rule and the second PCC rule to the SMF.

According to the first PCC rule and the second PCC rule, the SMF derives a QoS rule, a first QoS flow level parameter and a QoS flow level parameter set which are configured to the terminal, and a first QoS text and a QoS text set which are configured to the base station. The first QoS flow class parameter may also be referred to as a bundled PC5QoS flow class parameter, among others. After the SMF derives the QoS rule, the first QoS flow class parameter, the QoS flow class parameter set, the first QoS text, and the QoS text set, the SMF may configure the QoS rule, the first PC5QoS flow class parameter, and the QoS flow class parameter set to the UE in a Protocol Data Unit (PDU) session establishment procedure or a PDU session modification procedure, and configure the first QoS text and the QoS text set to the base station.

Further, after the configuration of the QoS of the PC5 is completed, the terminal may detect, in real time or periodically, a QoS flow class parameter actually currently met, and send a request to the network side according to the QoS flow class parameter actually met, so that the network side adjusts the QoS on the PC5 interface.

Specifically, in an embodiment, in a case that the base station is a base station in a relay scenario, after the sending the first QoS text and the QoS text set to the base station, the method further includes:

receiving a second index which is sent by a base station and matched with a first index in the QoS text set, wherein the first index is an index which is matched with a third QoS flow grade parameter in the QoS flow grade parameter set, and the third QoS flow parameter is a QoS flow grade parameter which is actually met by a terminal when a PC5 connection is detected;

and initiating a Protocol Data Unit (PDU) session change process according to the second index so as to change the User Plane Function (UPF) and the corresponding QoS of the base station.

Specifically, in another embodiment, when the base station is a base station in a relay scenario and the base station receives the third QoS flow parameter sent by the terminal, the base station directly sends the third QoS flow parameter to the PCF, and the PCF triggers the SMF to initiate a protocol data unit PDU session change process or a PC5 link release process controlled by the network.

For a better explanation, the following description will be made in detail with respect to a relay environment and a non-relay environment.

Scheme 1: in the case that the base station is a base station in a non-relay scenario, the base station may perform the following actions:

receiving first information sent by a terminal;

scheduling radio resources according to the first information;

the first information is a third QoS flow class parameter or a first index in the QoS flow class parameter set corresponding to the third QoS flow class parameter, and the third QoS flow class parameter is a QoS flow class parameter that is actually satisfied by the terminal detecting that the PC5 connection is connected.

Optionally, in an embodiment, when the first information is the first index, the scheduling, by the base station, radio resources according to the first information includes:

and scheduling related wireless resources according to the second QoS text matched with the first index in the QoS text set.

In another embodiment, in the case that the first information is the third QoS flow class parameter, the scheduling, by the base station, radio resources according to the first information includes:

and scheduling related wireless resources according to the third QoS flow grade parameter.

Scheme 2: in the case that the base station is a base station in a relay scenario, the base station may perform the following actions:

receiving first information sent by a terminal;

sending second information according to the first information, wherein the second information is used for triggering the session management function to initiate a Protocol Data Unit (PDU) session change process or initiate a network-controlled PC5 link release process;

In this embodiment, optionally, when the first information is the third QoS flow class parameter, the second information is the third QoS flow class parameter;

and when the first information is the first index, the second information is a second index of the QoS texts matched with the first index in the QoS text set.

It should be noted that the specific content of the first information may be determined by the terminal. In this embodiment, when the third QoS flow class parameter matches a second QoS flow class parameter in the QoS flow class parameter set, the first information is the first index;

the first information is the third QoS flow class parameter when the third QoS flow class parameter does not match a second QoS flow class parameter in the set of QoS flow class parameters.

For example, the terminal may detect the QoS flow class parameter on the current PC5 link, obtain a third QoS flow class parameter, and determine whether PC5QoS degradation or restoration is required according to the relationship between the third QoS flow class parameter and the first QoS class parameter. When downgrading or restoration is required, the third QoS flow class parameter may be matched to the second QoS flow class parameter in the set of QoS flow class parameters.

And if a second QoS flow class parameter in the QoS flow class parameter set is matched with the third QoS flow class parameter, the terminal reports a first index, wherein the first index is the index of the second QoS flow class parameter matched with the third QoS flow class parameter in the QoS flow class parameter set. It should be understood that the third QoS flow class parameter matching the second QoS flow class parameter may be understood as the third QoS flow class parameter and the second QoS flow class parameter having equal or close values.

If the second QoS flow class parameter matching the third QoS flow class parameter is not found in the QoS flow class parameter set, the terminal may directly transmit the third QoS flow class parameter.

For non-relay scenarios: if the base station receives that the first information reported by the UE is the first index, the base station retrieves a second QoS text matched with the first index in the QoS text set according to the first index, and then schedules related wireless resources according to the matched second QoS text to adjust the QoS of the PC 5. And if the first information reported by the UE and received by the base station is the third QoS flow grade parameter, the base station schedules the related wireless resources according to the third QoS flow grade parameter so as to adjust the QoS of the PC 5.

For the relay scenario: if the base station receives that the first information reported by the UE is the first index, the base station searches a second QoS text matched with the first index in the QoS text set according to the first index, then the base station initiates a PC5QoS notification process to notify the SMF of the second index corresponding to the matched second QoS text, and then the SMF initiates a PDU session change process to change the UPF and the QoS corresponding to the base station. If the base station receives the first information reported by the UE as the third QoS flow grade parameter, then the base station initiates a PC5QoS notification process to notify the PCF of the third QoS flow grade parameter, and the PCF triggers the SMF to initiate a PDU session change process or a network-controlled PC5 link release process. The behavior of the specific PCF depends on the reported third QoS flow class parameter.

In order to better understand the implementation process of the present invention, the following describes the QoS-related configuration flow of PC5 connection establishment and the PC5QoS downgrading or restoring flow in detail through specific examples.

As shown in fig. 3, the QoS-related configuration flow for PC5 connection establishment includes the following steps:

step 31, optionally, PDU session context establishment, authentication and authorization are performed between the terminal and the network device.

At step 32, the application server generates a PC5 communication service requirement. Specifically, after the PC5 proximity communication is found, the terminal and the proximity terminal need to establish PC5 communication based on the traffic demand, or the application server notifies the terminal and the proximity terminal to establish PC5 communication, and then the application server generates PC5 communication service demand.

Step 33, PDU session management policy is established or changed. Specifically, the application server interacts with the core network, and the PCF authorizes the service information of the application server. During the interaction, the application server may provide the PC5 communication service requirement to the core network, and according to the service information, the application server may further provide the PC5 alternative communication service requirement. If the application server provides the PC5 alternative communication service requirement, the application server may instruct the PCF to be responsible for QoS regulation on PC 5.

At step 34, the PCF derives PCC rules for PC5 communication. Specifically, the PCF derives a first PCC rule with PC5QoS parameters associated with PC5 communications based on the PC5 communications service requirements provided by the application server. If the application server provides the PC5 alternative communication service requirement, the PCF further derives a second PCC rule with an alternative PC5QoS parameter set associated with PC5 communication.

Step 35, PCF policy change process. Specifically, the PCF initiates a policy change procedure and provides PC5 communication-related PCC rules to the SMF.

At step 36, the SMF derives PC5 related parameters. Specifically, the SMF derives relevant parameters for PC5 communication, such as PC5QoS text and PC5QoS flow class parameters, according to the PCC rule (e.g., the first PCC rule) related to PC5 communication provided by the PCF. If the PCC rule (e.g., the second PCC rule) has an alternative PC5QoS parameter set in it, the SMF further derives an alternative PC5QoS text and an alternative PC5QoS flow class parameter.

At step 37, the SMF initiates a PDU session setup or change procedure. Specifically, the PC5QoS text and the alternative PC5QoS text can be provided to the NG-RAN through an N2 interface; the PC5QoS flow class parameter, the alternative PC5QoS flow class parameter and the QoS rule are provided to the terminal through the N1 interface.

Further, as shown in fig. 4, after the QoS related configuration established by the PC5 connection, the QoS of the PC5 can be degraded or restored, specifically, the degradation or restoration of the QoS of the PC5 includes the following steps:

in step 41, the terminal decides to downgrade or restore the QoS according to the QoS detection on the PC5 interface.

Step 42, the terminal sends a QoS downgrade or restore request to the NG-RAN. Specifically, if the UE detects that the QoS parameter (e.g., GFBR, PDB, PER) of the current PC5QoS flow does not satisfy the QoS flow class parameter configured by the network, the UE requests the network to perform resource configuration for QoS degradation; if the current PC5QoS flow of the UE is adjusted to the QoS flow grade parameter of a low grade, the UE detects that the QoS parameter (such as GFBR, PDB, PER) of the current PC5QoS flow meets the QoS flow grade parameter configured by the network, and the UE requests the network to execute the resource configuration of QoS recovery.

The NG-RAN performs either step 43a or step 43b depending on the current scenario.

In step 43a, the NG-RAN schedules resources according to the index or QoS parameters. Specifically, in a non-relay scenario, the NG-RAN matches the PC5QoS text according to an index of a PC5QoS stream level parameter provided by the UE, and performs PC5QoS stream resource allocation based on the PC5QoS text NG-RAN. If the UE provides the QoS parameters (such as GFBR, PDB, PER) of the currently detected PC5QoS flow, the NG-RAN performs PC5QoS flow resource allocation according to the QoS parameters of the currently detected PC5QoS flow provided by the UE.

Step 43b, the NG-RAN initiates a notification process to report the QoS parameters met on the PC5QoS text index or the actual PC5 interface. Specifically, in a relay scenario: the NG-RAN triggers the notification procedure and provides the matching PC5QoS text index to the core network, and then the SMF initiates the PDU session change procedure. If the UE provides the QoS parameters of the currently detected PC5QoS flow, the NG-RAN provides the QoS parameters of the actually detected PC5QoS flow to the PCF in a notification process, and then the PCF triggers the SMF to initiate a PDU session change or release process.

After the execution 43b the SMF performs 44, step 44, a PDU session change or release procedure. Further, the terminal may have step 45, to perform a PC5 link release procedure. Specifically, if the SMF in the core network performs the PDU session release procedure, the terminal may perform the PC5 link release procedure.
