Description

Priority processing method, equipment and storage medium for QoS (quality of service) rules

Technical Field

The present disclosure relates to communications technologies, and in particular, to a method, a device, and a storage medium for processing a priority of a Quality of Service (QoS) rule.

Background

In a fifth Generation mobile communication (5th Generation, 5G) network, a QoS model based on QoS flow (QoS flow) is proposed.

In a 5G network, a User Equipment (User Equipment, abbreviated to UE) may establish one or more Packet Data Unit (PDU) sessions (sessions) with the 5G network, and when or after the PDU Session is established, the network Equipment may establish a QoS flow (flow) for the UE to carry uplink and downlink Data, and the network Equipment configures one or more QoS rules (QoS rules) for each QoS flow, each QoS rule has a priority (Precedence), and each QoS rule includes one or more Packet filters (Packet filters). When UE needs to send uplink data, UE filters packet filters of QoS rules one by one according to the priority order of the QoS rules by using the transmission layer address of the data packet until a matched packet filter is found. The QoS flow to which the matched packet filter belongs is the bearer used by the uplink data, and provides the guaranteed quality of service for the QoS flow.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," and the like in the description and in the claims, and in the drawings, of the embodiments of the application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The 5G network is also called a New wireless communication system, New Radio, NR for short. The 5G network includes AN access network (AN for short) and a core network.

Fig. 1 is a schematic diagram of a 5G network architecture, and as shown in fig. 1, AN access network in a 5G system may be a radio access network (radio access network, abbreviated as (R) AN), and AN (R) AN device in the 5G system may be composed of a plurality of 5G- (R) AN nodes, where the 5G- (R) AN nodes may include: a new air interface base station (NR nodeB, abbreviated to gNB), a new generation evolved base station (NG-eNB), a Central Unit (CU), a Distributed Unit (DU), and the like, in a separate form, a gNB, a Transmission Receive Point (TRP), a Transmission Point (TP), an Access Point (AP) of a WIreless Fidelity (WiFi) network, or other nodes.

The core Network of the 5G Network includes Access and Mobility Management Function (AMF) Network elements, Session Management Function (SMF) Network elements, User Plane Function (UPF) Network elements, Policy Control Function (PCF) Network elements, Application Function (AF) Network elements, Unified Data Management (UDM) Network elements, Authentication Server Function (AUSF) Network elements, Network Slice Selection Function (Network Slice Selection Function, process NSSF) Network elements, and other functional units.

The AMF network element is mainly responsible for services such as mobility management, access management and the like. The SMF network element is mainly responsible for session management, address management and allocation of terminal devices, dynamic host configuration protocol functions, selection and control of user plane functions, and the like. The UPF network element is mainly responsible for routing and forwarding data packets, filtering messages, and executing QoS control related functions, etc., which are externally connected to a Data Network (DN) and a user plane. The PCF network element is mainly responsible for providing a unified policy framework for network behavior management, providing policy rules for control plane functions, obtaining registration information related to policy decisions, and the like. The AUSF is mainly responsible for authentication functions of the terminal device, and the like.

It should be noted that these functional units may work independently, or may be combined together to implement some control functions, such as access control and mobility management functions for access authentication, security encryption, location registration, etc. of the terminal device, and session management functions for establishment, release, and modification of a user plane transmission path, etc.

The functional units in the 5G network may communicate with each other through a next generation Network (NG) interface, for example: the method comprises the steps that terminal equipment can transmit control plane messages with AN AMF network element through AN NG interface 1 (N1 for short), AN AN equipment can establish a user plane data transmission channel with a UPF network element through AN NG interface 3 (N3 for short), the AN equipment can establish control plane signaling connection with the AMF network element through AN NG interface 2 (N2 for short), the UPF network element can perform information interaction with the SMF network element through AN NG interface 4 (N4 for short), the AMF network element can perform information interaction with the SMF network element through AN NG interface 11 (N11 for short), the SMF network element can perform information interaction with the network element through AN NG interface 7 (N7 for short), the UDM network element interacts with the AMF network element through AN interface 8 (N8 for short), and the UDM network element interacts with the SMF network element through AN interface 10 (N10 for short).

It should be noted that the network elements of the core network of the 5G network may include other functional units besides the functional units shown in fig. 1.

The embodiment of the application relates to a terminal device which can be: the mobile phone and the computer may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a smart phone, a Personal Digital Assistant (PDA), a computer, a laptop computer, a handheld communication device, a handheld computing device, a satellite wireless device, a wireless modem card, a Set Top Box (STB), a vehicle-mounted device, a wearable device (such as a smart watch, a smart band, and smart glasses), a smart home device, other devices for communicating on a wireless system, and the like.

In the prior art, after a terminal device and a network device establish a QoS flow (flow), a plurality of PCF network elements allocate a priority of a QoS rule (QoS rule) to the same terminal device, and each PCF independently allocates the priority of the QoS rule to the terminal device, which may cause the priorities of the QoS rules to be the same.

In order to solve the problem of the prior art, an embodiment of the present application provides a method for processing priorities of QoS rules, where a network element allocates priorities of QoS rules of terminal devices, so that it can be ensured that priorities allocated to different QoS rules of the same terminal device are not repeated. Or, the network element that allocates the priority of the second QoS rule to the terminal device obtains the priority of the first QoS rule that the terminal device has, and when allocating the priority of the second QoS rule, the priority of the first QoS rule that the terminal device has is not used, so that it can be ensured that the priorities allocated to different QoS rules of the same terminal device are not repeated.

Based on the network architecture shown in fig. 1, a method for processing the priority of the QoS rule is provided in an embodiment of the present application, and fig. 2 is a signaling flowchart of the method for processing the priority of the QoS rule provided in the embodiment of the present application, as shown in fig. 2, the method provided in the embodiment includes the following steps:

s101, the terminal equipment sends the NAS information to the AMF network element.

The first session management request may be carried in a Non-access stratum (NAS) message (message) sent by the terminal device to the AMF network element. The first session management request is for requesting to establish or modify a session, and unlike the prior art, in the present embodiment, the first session management request message includes a priority (precedence) of a first QoS rule that the terminal device has. In this embodiment of the present application, the priority of the first QoS rule that the terminal device has means: before the session is established or modified, the terminal device already has the priority of the QoS rule, the priority of the first QoS rule may be the QoS rule that the terminal device itself or another device has allocated to the terminal device, and the priority may be an index or an ID of the priority.

When the first session management request is for requesting a session to be established, the first session management request is also referred to as first session establishment request, and when the first session management request is for requesting a session to be modified, the first session management request is also referred to as first session modification request.

The NAS message is forwarded to the AMF network element by the AN, and it can be understood that the message sent to the core network element by the terminal device is forwarded through the AN, and similarly, the message sent to the terminal device by the core network element is also forwarded through the AN.

The NAS message further includes an identifier (ID for short) of the PDU session to be managed and an ID of the terminal device. When the first Session management Request is used to Request to establish a Session, the first Session management Request is, for example, a PDU Session Establishment Request (Packet Data Unit Session Establishment Request) message.

The priority of the first QoS rule may be allocated by the PCF network element or may be allocated by the terminal device. Or, a part of the priorities of the first QoS rules are assigned by the PCF network element, and another part of the priorities are assigned by the terminal device. Different from the prior art, in this embodiment, the terminal device may allocate a priority to the QoS rule by itself.

And S102, the AMF network element sends a second session management request to the SMF network element.

The sending, by the AMF network element, the second session management request to the SMF network element may be a call to a UE Context (UE Context) service of the SMF, for example: creation, modification, etc., may also be a piece of signaling.

The first session management request may be carried in the second session management request.

The second Session management Request transmitted between the AMF network element and the SMF network element may be a Create Session Request (Create Session Request) message, in this embodiment, the AMF network element only forwards the first Session management Request sent by the terminal device, and does not process the content of the first Session management Request.

And the second session management request sent by the AMF network element to the SMF network element comprises the ID of the terminal equipment.

S103, the SMF network element sends a third session management request to the PCF network element.

After receiving the second session management request, the SMF network element sends a third session management request to the PCF network element according to the first session management request, where the third session management request includes the ID of the terminal device and the priority of the first QoS rule. In an embodiment, the third session management request may further include an ID of the PDU session.

The content carried by the first session management request, the second session management request and the third session management request may be the same, but the protocol or interface used for transmitting each message may be different, and therefore, the first, second and third session management requests are used for distinguishing.

S104, the PCF network element determines the priority corresponding to a Policy Control and Charging (PCC) rule (rule) according to the priority of the first QoS rule.

When determining the priority corresponding to the PCC rule, the PCF network element does not use the priority of the first QoS rule, and in general, each PCC rule corresponds to one priority.

The priority corresponding to the PCC rule is used for determining the priority of the QoS rule, so that the uniqueness of the priority of the QoS rule in the terminal equipment can be ensured by ensuring the uniqueness of the priority corresponding to the PCC rule in the terminal equipment.

And S105, the PCF network element sends a response message of the third session management request to the SMF network element.

The response message of the third session management request includes the PCC rule and the priority corresponding thereto, and may further include a QoS parameter, a Service Data Flow Descriptor (Service Data Flow Descriptor), and the like.

After receiving the PCC rule, the SMF network element takes a priority corresponding to the PCC rule as a priority of a second QoS rule, the priority of the second QoS rule is different from the priority of the first QoS rule, a service data Flow Descriptor in the PCC rule is taken as a Packet Filter (Packet Filter) of the QoS rule, and a QoS parameter in the PCC rule is taken as a QoS Flow Descriptor (QoS Flow Descriptor).

If the SMF network element creates a QoS Flow for the terminal equipment, a QoS Flow Identifier (QFI for short) is allocated to the created QoS, and the QFI is used for uniquely identifying one QoS Flow in the session. If the SMF network element modifies the QoS flow for the terminal equipment, no QFI needs to be allocated.

S106, the SMF network element sends a response message of the first session management request to the terminal equipment.

The SMF network element sends a response message of the first session management request to the terminal device through the AMF network element, for example, the SMF network element sends a response message of the second session management request to the AMF network element, the response message of the second session management request includes the response message of the first session management request, and the AMF network element sends the response message of the first session management request to the terminal device.

The response message of the first Session management request is, for example, a PDU Session Establishment Accept (PDU Session Establishment Accept), the response message of the first Session management request includes the priority of the QFI, the QoS flow descriptor and the second QoS rule, and the QoS rule includes the priority of the second QoS rule.

The priority of the second QoS rule allocated at this time is different from the priority of the first QoS rule which the terminal equipment has, so that the priorities allocated to different QoS rules of the same terminal equipment can be ensured not to be repeated. When the terminal equipment transmits the uplink data, the terminal equipment cannot be matched with a plurality of QoS rules with the same priority, so that the normal transmission of the uplink data can be ensured.

And S107, the SMF network element sends a fourth session management request to the UPF network element.

The SMF network element converts the PCC Rule into a Packet Detection Rule (Packet Detection Rule), and carries the Packet Detection Rule in a fourth session management request to send to the UPF network element, so that the UPF network element sends downlink data according to the Packet Detection Rule.

In an embodiment, the UPF network element may return a response message of the fourth session management request to the SMF network element.

In this embodiment, in a session management process, a terminal device reports a priority of a first QoS rule that the terminal device has to a PCF network element, so that the PCF network element determines a priority corresponding to a PCC rule according to the priority of the first QoS rule, and sends the priority corresponding to the PCC rule to an SMF network element, where the priority corresponding to the PCC rule is used to determine a priority of a second QoS rule, and the uniqueness of the priority corresponding to the PCC rule in the terminal device is ensured. Therefore, even if a plurality of PCF network elements distribute the priority of the QoS rule to the terminal equipment, the priority distributed to the same terminal equipment can be ensured not to be repeated, and the normal transmission of the uplink data can be ensured.

Fig. 3 is a signaling flowchart of a method for processing priority of QoS rules according to a second embodiment of the present application, and as shown in fig. 3, the method according to the present embodiment includes the following steps:

s201, the terminal equipment sends an NAS message to an AMF network element.

The NAS message includes a first session management request requesting establishment or modification of a session. The NAS message may further include an ID of the PDU session to be managed and an ID of the terminal device.

Unlike the scheme of the first embodiment, the priority of the first QoS rule that the terminal device has is not included in the first session management request.

S202, the AMF network element sends a second session management request to the SMF network element.

The first session management request may be carried in a second session management request, where the second session management request includes an ID of the terminal device.

S203, the SMF network element sends a third session management request to the PCF network element.

After receiving the second session management request, the SMF network element sends a third session management request to the PCF network element, where the third session management request includes the ID of the terminal device.

And S204, the PCF network element sends a response message of the third session management request to the SMF network element.

The response message of the third session management request includes a PCC rule, and the PCC rule includes QoS parameters and a service data flow descriptor.

Different from the first embodiment, the PCC rule does not include the priority corresponding to the PCC rule, or the SMF ignores the priority in the PCC rule.

S205, the SMF network element sends a priority assignment request to the AMF network element.

The priority allocation request is used for requesting the AMF network element to allocate the priority of the second QoS rule to the terminal equipment, the priority allocation request comprises the ID of the terminal equipment and the number of the priorities requested to be allocated, and the number of the priorities requested to be allocated is the same as the number of the QoS rules.

S206, the AMF network element sends a response message of the priority allocation request to the SMF network element.

And after receiving the priority allocation request, the AMF network element allocates the priority of the second QoS rule to the terminal equipment according to the priority allocation request, and for one terminal equipment, only one AMF network element is associated, namely the terminal equipment and the AMF network element are in one-to-one correspondence.

Therefore, the priorities of all the QoS rules of the terminal device are allocated by the AMF network element, and the AMF network element stores the priority of the first QoS rule of the terminal device, so that the priority of the first QoS rule can not be used when allocating the priority of the second QoS rule to the terminal device, thereby ensuring that the priority of the second QoS rule is different from the priority of the first QoS rule.

Or, the allocation rule of the AMF network element can ensure that the priorities of the QoS rules allocated to the same terminal device are not repeated.

And the AMF network element carries the priority of the second QoS rule allocated for the terminal equipment in a response message of the priority allocation request and sends the response message to the SMF network element.

S207, the SMF network element sends a response message of the first session management request to the terminal equipment.

And the SMF network element takes the priority included in the priority allocation response as the priority of the second QoS rule, takes the service data flow descriptor in the PCC rule as a packet filter of the QoS rule, and takes the QoS parameter in the PCC rule as the QoS flow descriptor. And if the SMF network element establishes a QoS flow for the terminal equipment, QFI is distributed to the established QoS.

The SMF network element sends a response message of a first session management request to the terminal equipment through the AMF network element, wherein the response message of the first session management request is, for example, PDU session establishment acceptance, the response message of the first session management request comprises QFI, a QoS flow descriptor and a second QoS rule, and the second QoS rule comprises the priority of the second QoS rule.

And S208, the SMF network element sends a fourth session management request to the UPF network element.

And the SMF network element converts the QoS rule into a packet detection rule, and the packet detection rule is carried in the fourth session management request and is sent to the UPF network element, so that the UPF network element can send downlink data according to the packet detection rule.

In this embodiment, after receiving a first session management request sent by a terminal device, an SMF network element obtains a PCC rule from a PCF network element, and sends a priority assignment request to an AMF network element after obtaining the PCC rule, where the AMF network element assigns a priority of a second QoS rule to the terminal device, and sends the priority of the second QoS rule to the SMF network element by carrying the priority of the second QoS rule in a response message of the priority assignment request, where the priority of the second QoS rule is different from the priority of a first QoS rule that the terminal device has. In the method, the AMF network element uniformly allocates the priority to the QoS rule of the terminal equipment, so that the priority of the QoS rule allocated to the same terminal equipment is not repeated, and the normal transmission of the uplink data can be ensured.

Fig. 4 is a signaling flowchart of a method for processing priority of QoS rules according to a third embodiment of the present application, and as shown in fig. 4, the method according to the present embodiment includes the following steps:

s301, the terminal equipment sends the NAS message to the AMF network element.

The NAS message includes a first session management request.

S302, the AMF network element sends a second session management request to the SMF network element.

S303, the SMF network element sends the third session management request to the PCF network element.

The implementation manner of steps S301 to S303 is the same as that of steps S201 to S203 in the second embodiment, and is not described herein again.

S304, the PCF network element sends a query request to a User Data Repository (UDR) network element.

The UDR network element is configured to store user data of the terminal device, where the user data includes a priority of a first QoS rule that the terminal device has, and the UDR network element may use an ID of the terminal device as an index of the priority of the QoS rule to establish a correspondence between the two.

The inquiry request is used for requesting the priority of the first QoS rule from the UDR network element, the inquiry request comprises the ID of the terminal equipment, and the UDR network element inquires the priority of the first QoS rule of the terminal equipment according to the ID of the terminal equipment.

S305, the UDR network element sends a response message of the query request to the PCF network element, where the response message of the query request includes a priority of a first QoS rule that the terminal device has.

And after receiving the query request, the UDR network element queries the priority of the first QoS rule according to the identifier of the terminal equipment, and carries the priority of the first QoS rule in a response message of the query request to send the response message to the PCF network element.

S306, the PCF network element determines the priority corresponding to the PCC rule according to the priority of the first QoS rule.

And the PCF network element does not use the priority of the first QoS rule when determining the priority corresponding to the PCC rule, and the priority corresponding to the PCC rule is used for determining the priority of the QoS rule.

S307, the PCF network element sends a response message of the third session management request to the SMF network element.

The response message of the third session management request includes the PCC rule and the corresponding priority, and may further include a QoS parameter, a service data flow descriptor, and the like.

After receiving the PCC rules, the SMF network element takes the priority corresponding to the PCC rules as the priority of a second QoS rule, the priority of the second QoS rule is different from the priority of the first QoS rule, a service data flow descriptor in the PCC rules is taken as a packet filter of the QoS rules, and a QoS parameter in the PCC rules is taken as a QoS flow descriptor.

And if the SMF network element newly builds a QoS flow for the terminal equipment, QFI is distributed to the newly built QoS. If the SMF network element modifies the QoS flow for the terminal equipment, no QFI needs to be allocated.

S308, the SMF network element sends a response message of the first session management request to the terminal equipment.

The priority of the second QoS rule allocated to the terminal equipment every time is different from the priority of the first QoS rule of the terminal equipment, so that the priorities allocated to different QoS rules of the same terminal equipment can be ensured not to be repeated. When the terminal equipment transmits the uplink data, the terminal equipment cannot be matched with a plurality of QoS rules with the same priority, so that the normal transmission of the uplink data can be ensured.

S309, the SMF network element sends a fourth session management request to the UPF network element.

S310, PCF network element sends update request to UDR network element.

The update request is used for requesting to update the priority of the first QoS rule which the terminal device has and which is stored on the UDR network element, and the update request includes the ID of the terminal device and the priority corresponding to the PCC rule.

S311, the UDR network element updates the priority of the first QoS rule according to the updating request.

And after receiving the update request, the UDR network element takes the priority corresponding to the PCC rule in the update request as the priority of the QoS rule to be updated, and updates the priority of the first QoS rule stored locally. Therefore, the data requested from the UDR network element each time is the latest data, which can be ensured by the PCF network element or other PCF network elements corresponding to the terminal equipment.

In this embodiment, after receiving the third session management request sent by the SMF network element, the PCF network element sends an inquiry request to the UDR network element, where the inquiry request is used to request to inquire the priority of the first QoS rule that the terminal device has, and the PCF network element determines the priority corresponding to the PCC rule according to the priority of the first QoS rule, and sends the priority corresponding to the PCC rule to the SMF network element, where the priority corresponding to the PCC rule is used to determine the priority of the second QoS rule, and the uniqueness of the priority corresponding to the PCC rule in the terminal device can be ensured. Therefore, even if a plurality of PCF network elements exist, the priorities distributed to the same terminal equipment can be ensured not to be repeated, and the normal transmission of uplink data can be ensured.

In the third embodiment, the PCF network element requests the UDR network element for the priority of the first QoS rule. In other embodiments of the present application, after S302, the SMF network element may also send, according to the first session management request, an inquiry request to the UDR network element, where the inquiry request includes an identifier of the terminal device, and the SMF network element receives a response message of the inquiry request sent by the UDR network element, where the response message of the inquiry request includes a priority of the first QoS rule.

After acquiring the priority of the first QoS rule from the UDR network element, the SMF network element sends a third session management request message to the PCF network element, where the third session management request message includes the priority of the first QoS rule, and the subsequent steps refer to steps S306 to S311, which are not described herein again.

Fig. 5 is a signaling flowchart of a method for processing priority of QoS rules according to a fourth embodiment of the present application, and as shown in fig. 5, the method according to the present embodiment includes the following steps:

s401, the terminal equipment sends NAS information to the AMF network element.

The NAS message includes a first session management request.

S402, the AMF network element sends a second session management request to the SMF network element.

S403, the SMF network element sends the third session management request to the first PCF network element.

The implementation of steps S401 to S403 is the same as that of steps S201 to S203 in the second embodiment, and is not described here again.

S404, the first PCF network element determines the priority corresponding to the PCC rule according to the priority of the QoS rule which the terminal equipment has.

Wherein the priority of the first QoS rule is UDR network element, and the priority of the QoS rule of the terminal equipment is sent to the first PCF network element after being updated.

And when determining the priority corresponding to the PCC rule, the first PCF network element does not use the priority of the first QoS rule, and the priority corresponding to the PCC rule is used for determining the priority of the QoS rule.

S405, the first PCF network element sends a response message of the third session management request to the SMF network element.

S406, the SMF network element sends a response message of the first session management request to the terminal equipment.

S407, the SMF network element sends the fourth session management request to the UPF network element.

S408, the first PCF network element sends a first updating request to the UDR network element.

The first update request is used for requesting to update the priority of the first QoS rule of the terminal equipment stored on the UDR network element, and the first update request comprises the ID of the terminal equipment and the priority corresponding to the PCC rule.

And S409, updating the priority of the first QoS rule by the UDR network element according to the first updating request.

And after receiving the first updating request, the UDR network element updates the priority of the first QoS rule which the terminal device locally stores, by using the priority corresponding to the PCC rule included in the first updating request as the priority of the QoS rule to be updated.

For example, if priorities of three QoS rules are newly allocated to the terminal device, the UDR network element merges the newly allocated priorities of the three QoS rules with the priority of the first QoS rule of the terminal device stored locally.

S410, the UDR network element sends a second updating request to the second PCF network element, wherein the second updating request comprises the priority of the QoS rule to be updated.

In this embodiment, the first PCF network element and the second PCF network element are both PCF network elements corresponding to terminal devices, one terminal device generally corresponds to multiple PCF network elements, when the first PCF network element allocates a priority to a terminal device, the allocated priority is updated to the UDR network element, and the UDR network element synchronizes the allocated priority to other PCF network elements corresponding to the terminal device. Therefore, the priority of the QoS rule which is stored on all PCFs corresponding to the terminal equipment and is allocated to the terminal equipment is ensured to be the latest data.

The UDR network element may send only the priority of the QoS rule to be updated to the second PCF network element, e.g. if three new priorities are added, the three priorities are sent to the second PCF.

The UDR network element may also send the priorities of the first QoS rules to the second PCF network element, and after receiving the second update request, the second PCF network element replaces the locally stored priority of the first QoS rule with the priority of the first QoS rule included in the second update request.

The difference between this embodiment and the third embodiment is: after receiving the second session management request, the first PCF network element does not need to query the UDR network element for the priority of the first QoS rule. In this embodiment, the priority of the first QoS rule is sent to the first PCF network element by the UDR network element in advance, so that time and signaling overhead for the PCF network element to query the UDR network element for the priority of the first QoS rule are saved, and the allocation efficiency of the priority is accelerated.

In this embodiment, after the priority of the terminal device on the UDR network element is updated, the UDR network element may synchronize all PCF network elements corresponding to the terminal device, so as to ensure that the priorities of the first QoS rules stored in all PCFs corresponding to the terminal device are the latest data, and each PCF network element does not need to request the priority of the first QoS rule from the UDR network element, thereby saving time and signaling overhead.

It should be noted that, in other embodiments of the present disclosure, the UDR network element may also be a PCF network element, where the PCF network element is configured to perform unified management on the priority of the QoS rule of the terminal device, and the PCF network element stores the priority of the first QoS rule that the terminal device has, and a specific allocation process is the same as in the third and fourth embodiments, and is not described herein again. The PCF network element for uniformly managing the priority of the QoS rules of the terminal device is also referred to as a high-order PCF network element, a management PCF network element, or a second PCF network element.

In the foregoing embodiment, the terminal device sends the first session management request to the SMF, so as to trigger the SMF network element to acquire the priority of the second QoS rule of the terminal device from the first network element. In a possible implementation manner of the present application, the SMF network element may also be triggered by another core network element to acquire the priority of the second QoS rule of the terminal device from the first network element.

In an exemplary manner, the first network element is a PCF network element, the PCF network element sends an update message of the PCC rule to the SMF network element, and the SMF network element takes the updated priority of the PCC rule as the priority of the second QoS rule and sends the priority of the second QoS rule to the terminal device.

In another exemplary manner, the SMF network element receives an indication message sent by the core network element, where the indication message is used to indicate a priority for modifying or allocating the QoS rule to the terminal device, and the SMF network element obtains the priority of the second QoS rule from the first network element according to the indication message.

When the first network element is the AMF network element, the SMF network element requests the AMF network element to allocate the priority of the second QoS rule to the terminal device according to the indication message, and the allocation procedure refers to the description of embodiment two, which is not described herein again.

When the first network element is a PCF network element, the SMF network element requests the PCF network element to allocate the priority of the second QoS rule to the terminal device, and the allocation process refers to the description of the first embodiment, the third embodiment, and the fourth embodiment, which is not described herein again.

And S505, the UDR network element allocates the priority of the second QoS rule to the terminal equipment according to the priority allocation request.

In the method, the UDR network element uniformly distributes the priority of the QoS rule to the terminal equipment in the network, and the UDR network element distributes the priority of the second QoS rule with corresponding number to the terminal equipment according to the priority number of the request distribution included in the priority distribution request.

The UDR network element stores the priority of the first QoS rule that the terminal device has, and can not use the priority of the first QoS rule when allocating the priority of the second QoS rule to the terminal device, thereby ensuring that the allocated priority of the second QoS rule is different from the priority of the first QoS rule that the terminal device has. Or, the allocation rule of the UDR network element can ensure that the priorities of the QoS rules allocated to the same terminal device are not repeated.

S506, the UDR network element sends a response message of the priority allocation request to the PCF network element.

The response message of the priority allocation request includes the priority of the second QoS rule allocated to the terminal device.

The response message of the third session management request includes the PCC rule and the priority of the second QoS rule, and the PCC rule includes the QoS parameter and the service data flow descriptor. The PCC rule does not include the priority corresponding to the PCC rule, or the SMF ignores the priority in the PCC rule.

S508, the SMF network element sends a response message of the first session management request to the terminal device.

The SMF network element takes the priority of the QoS rule included in the response message of the third session management request as the priority of the second QoS rule, takes the service data flow descriptor in the PCC rule as the packet filter of the QoS rule, and takes the QoS parameter in the PCC rule as the QoS flow descriptor. And if the SMF network element establishes a QoS flow for the terminal equipment, QFI is distributed to the established QoS.
