Description

Information processing method, device, equipment and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information processing method, an information processing apparatus, information processing equipment, and a computer-readable storage medium.

Background

The 5G network provides a concept of network slicing, that is, a logical network supporting a certain service, and four types of slices, such as eMBB (Enhanced Mobile Broadband), URLLC (Ultra-Reliable and Low Latency Communications), mliot (mass IoT, large-scale internet of things), and V2X (vehicle to external information exchange), are currently defined. The Network Slice is identified as S-NSSAI (Single Network Slice Selection Assistant Information).

Slice selection is performed in two processes, one is a registration process in which the network selects the AMF (Access and Mobility Management Function) serving the UE (User Equipment) and determines the network slice that the UE is allowed to use; second, a PDU (Protocol Data Unit) Session establishment process, in which the AMF selects a slice and an SMF (Session Management Function) in the slice, and then the SMF is responsible for completing establishment of a user plane connection.

The maximum downlink throughput is the downlink maximum data rate supported by the network slice, and the maximum uplink throughput is the uplink maximum data rate supported by the network slice. To control the maximum data rate of a network slice, the network may control the rate of each UE within the slice. However, there is no relevant solution on how to control the rate of the UE within a slice.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

Referring to fig. 1, fig. 1 is a flowchart of an information processing method according to an embodiment of the present invention, applied to an NWDAF, as shown in fig. 1, including the following steps:

step 101, information of the slice is acquired.

Wherein the information of the slice comprises at least one of: a rate of slices obtained from an OAM or RAN node or UPF, an average or peak slice rate of UEs of different priorities obtained from an AMF or PCF or RAN node, an average or peak slice rate of UEs obtained from a PCF, AMF, RAN or session management function SMF.

In an embodiment of the invention, the NWDAF may obtain the rate of slicing from the OAM. For example, the NWDAF may subscribe to the OAM for the rate of slices and then receive the rate of slices returned by the OAM.

Step 102, determining a rate-related analysis result of the UE in the slice according to the slice information and the slice information;

and 103, sending the analysis result related to the speed of the UE in the slice to a target network element.

The rate-related analysis result of the UE in the slice may include a rate range, a maximum rate, a range of the maximum rate, a variation trend of the UE slice rate, and the like.

In this embodiment of the present invention, the NWDAF may obtain the rates of the UEs with different priorities in the slice from the OAM or RAN node or UPF, and then send the rates of the UEs with different priorities in the slice to the target network element.

In practical applications, the target network element may be a PCF, an AMF, an OAM, a UDM, a UDR, or the like. If the target network element is a PCF, in the embodiment of the present invention, the NWDAF may receive a slicing rate analysis subscription request sent by the PCF, and obtain the slicing rate according to the slicing rate analysis subscription request. And then, the NWDAF sends a rate-related analysis result of the UE in the slice to a target network element according to the slice rate analysis subscription request.

In order to improve the accuracy of controlling the rate of the UE in the slice, in the embodiment of the present invention, the NWDAF obtains the information of the UE, obtains an analysis result related to the rate of the UE in the slice according to the information of the slice and the information of the UE, and obtains an analysis result related to the rate of the UE in the slice by using different strategies. Wherein the information of the UE comprises at least one of service behavior of the UE, subscription information of the UE, priority of the UE and capability of the UE.

The service behavior of the UE may be an application identifier, a network slice identifier, a data network name, and a UE behavior. The UE behavior may be a desired UE movement trajectory, power indication, traffic attributes, and the like.

In practical applications, the internal processing logic of the NWDAF is: the slicing rates of the UEs with different priorities are analyzed in a random sampling manner, and at this time, the NWDAF needs to consider the rate of the UE in the slice, the service behavior of the UE, subscription information of the UE, the priority of the UE, the capability of the UE, and the like. And then the NWDAF adjusts the slicing rates which can be used by the UE with different priorities according to the slicing information, and ensures that the sum of the slicing rates which can be used by the UE with different priorities does not exceed the slicing rate.

In the embodiment of the invention, according to the acquired slice information, the NWDAF sends the analysis result related to the speed of the UE in the slice to the target network element, thereby realizing the control of the speed of the UE in the slice.

Referring to fig. 2, fig. 2 is a flowchart of an information processing method provided by an embodiment of the present invention, and is applied to a target network element. The target network element may be a PCF or an AMF, etc. As shown in fig. 2, the method comprises the following steps:

and step 201, acquiring a speed-related analysis result of the UE in the slice from the NWDAF.

Specifically, if the target network element is a PCF, an OAM, a UDM, or a UDR, the PCF or OAM may send a slice rate analysis subscription request to the NWDAF, and receive an analysis result related to a rate of the UE in a slice, which is sent by the NWDAF according to the slice rate analysis subscription request.

Step 202, determining the speed of the target UE in the slice according to the analysis result related to the speed of the UE in the slice; or determining a PCC strategy, an MA PDU session strategy or a UE strategy of the target UE according to the analysis result related to the speed of the UE in the slice; or determining the rate of the target UE in the slice according to the analysis result related to the rate of the UE in the slice, and sending the rate to the PCF.

In practical applications, if the target network element is PCF or OAM, then PCF or OAM may determine the rate of the target UE within a slice according to the analysis result related to the rate of the UE within the slice sent by NWDAF. Wherein the target UE refers to any UE in a slice.

Or, in order to improve the accuracy of control, the PCF or OAM may further determine the rate of the target UE in the slice in combination with the UE information obtained from the AMF or UDM, and specifically, the PCF or OAM obtains the UE information and determines the rate of the target UE in the slice according to the rate of the UE in the slice and the UE information.

Wherein the information of the UE comprises at least one of service behavior of the UE, subscription information of the UE, priority of the UE and capability of the UE.

Specifically, the PCF may determine the rate of the target UE within the slice according to the rate of the UE within the slice and information of the UE. In the decision process, the PCF may make the decision according to a preset policy.

In practical applications, if the target network element is the AMF, the AMF may obtain the slice rate of the subscription of the UE and the priority of the UE from the UDM, and send the slice rate of the subscription of the UE and the priority of the UE to the PCF.

In addition, if the target network element is an AMF or a PCF, it may also send the average or peak slicing rate of UEs of different priorities to the NWDAF; or sending the average or peak slicing rate of the UE to the NWDAF.

Referring to fig. 3, fig. 3 is a flowchart of an information processing method according to an embodiment of the present invention, and is applied to OAM. As shown in fig. 3, the method comprises the following steps:

step 301, the rate of the slice is obtained from the RAN node or the UPF.

Upon receiving a subscription request for the NWDAF, the OAM may obtain the rate of the slice from the RAN node or the UPF.

Step 302, sending the slice rate to the NWDAF.

In response to a subscription request of the NWDAF, the OAM may send the rate of the slice to the NWDAF.

In addition, in order to further improve the accuracy of rate control of the UE within a slice, the OAM may further obtain, from the RAN node or the UPF, a rate of the UE within the slice, and send the rate of the UE within the slice to the NWDAF.

Referring to fig. 4, fig. 4 is a flowchart of an information processing method according to an embodiment of the present invention, and the information processing method is applied to a RAN node or a UPF. As shown in fig. 4, the method comprises the following steps:

step 401, sending the rate of slicing to OAM or NWDAF.

For example, a RAN node or a UPF receives a subscription request of OAM, and sends a slicing rate to the OAM according to the subscription request.

In addition, the RAN node or UPF may also send the rate of the UE within the slice to the OAM or to the NWDAF.

For example, the RAN node or UPF may send the rate of the UE within the slice to the OAM or to the NWDAF according to a subscription request of the OAM or the NWDAF.

In addition, the RAN node may also send to the NWDAF an average or peak slicing rate for UEs of different priorities; or sending the average or peak slicing rate of the UE to the NWDAF.

For example, the RAN node or UPF may send the average or peak slice rate of UEs of different priorities to the OAM or to the NWDAF according to a subscription request of the OAM or the NWDAF.

Referring to fig. 5, fig. 5 is a flowchart illustrating a PCF dynamically adjusting a rate of a UE within a slice according to an analysis result of an NWDAF according to an embodiment of the present invention. As shown in fig. 5, the process specifically includes:

501. the PCF subscribes to slice rate analysis from the NWDAF.

Specifically, the PCF sends NWDAF _ analysis subscription to the NWDAF for subscribing to rate analysis of the slice. Wherein the PCF may provide the slice identification to the NWDAF; if not, it indicates that the PCF subscribes to the rate analysis result of all slices.

502. NWDAF subscribes to the OAM for the slice rate.

503. The OAM obtains the rate of the slice and the rate of the UE within the slice from the RAN node or UPF and performs data processing.

For example, OAM calculates the average slice rate from the rate of slices provided by the RAN node or UPF. If the PCF provides the slice identification, the NWDAF provides the slice identification to the OAM.

504. The OAM informs the NWDAF of the rate of the slice and the rate of the UE within the slice.

505. The NWDAF performs data analysis according to the information provided by the OAM and the UE priority, and determines the data rate that the UE with different priorities can use in a slice, i.e. the rate of the UE in the slice, such as the maximum uplink bit rate of the slice of the UE, the maximum downlink bit rate, the slice aggregation bit rate of the UE, and the like.

The NWDAF firstly analyzes the rate of the UE in the slice, and determines the slice rates used by the UE with different priorities according to the rate of each UE in the slice, the service behavior of the UE and the subscription priority of the UE, which are acquired from the UDM or the AMF and provided by the OAM.

In this process, the NWDAF may determine the slicing rates used by UEs with different priorities in a random sampling manner. Then, the NWDAF adjusts the slicing rates that the UEs with different priorities can use according to the slicing rates, so as to ensure that the sum of the rates of the UEs with different priorities in the slice does not exceed the slicing rate.

506. The NWDAF sends the data analysis results to the PCF.

Specifically, the NWDAF sending NWDAF _ analysis description _ Notify to the PCF by the NWDAF may include: slice identity, UE priority/area, UE rate within a slice.

507. And the PCF updates the rate of the UE in the slice according to the analysis result of the NWDAF. The PCF sends an Npcf _ AMFPolicyControl _ UpdateNotify message to the AMF, and the parameters comprise AM strategy association ID, slice identification and the rate of the UE in the slice.

508. The AMF sends an N2 request to the RAN, the message including the slice identity and the UE's rate within the slice.

509. The RAN returns an N2 reply to the AMF.

Referring to fig. 6, fig. 6 is a flowchart illustrating an AMF determining a rate of a UE in a slice for the UE during a registration procedure according to an embodiment of the present invention. The method specifically comprises the following steps:

601. the UE sends a registration request to the AMF.

602. The AMF sends a numm _ SDM _ Get Request (numm _ SDM _ Get _ Request) to the UDM, the message including a SUPI (Subscription Permanent Identifier).

603. The UDM returns a Nudm _ SDM _ Get reply message (Nudm _ SDM _ Get _ Response) to the AMF, the message including the slice rate of the subscribed UE, the UE priority.

604. The AMF sends an Npcf _ amplilicocontrol _ Create Request message (Npcf _ amplilicocontrol _ Create _ Request) to the PCF, and the parameters are a slice identifier, a slice rate of the subscribed UE, a UE priority or a UE location.

605. The PCF may modify the rate of the UE within the slice according to operator policy.

Meanwhile, the PCF may send an Npcf _ amplilicocontrol _ Create reply message (Npcf _ amplilicocontrol _ Create _ Response) to the AMF. Wherein, the message is carried as a slice identifier, and the rate of the UE within the slice.

In particular, the PCF may adjust the rate of the UE within the slice based on the information obtained from the AMF and the rate of the NWDAF active UE within the slice in the manner of the embodiment shown in fig. 5.

606. The AMF sends an N2 message to the RAN, the message including the slice identity, the UE's rate within the slice, and a registration accept message.

607. The RAN sends a registration accept message to the UE.

Referring to fig. 7, fig. 7 is a flowchart of OAM obtaining a slice rate from a RAN node or UPF according to an embodiment of the present invention. The method specifically comprises the following steps:

701. OAM sends subscription/measurement request message to RAN node or UPF, and the parameters are slice rate and reporting threshold.

702. When the RAN node or the UPF finds that the slicing rate reaches a reporting threshold, the RAN node or the UPF sends information/event report to the OAM.

And then, when OAM reports to NWDAF, the area and the slicing rate in the area can also be reported to NWDAF.

In an embodiment of the present invention, the NWDAF determines the analysis result related to the slicing rate of the UE, such as the range of the slicing rate of the UE, the maximum value of the slicing rate of the UE and the duration of the rate, the time or duration that the slicing rate of the UE reaches/exceeds the maximum value, the maximum value or range of the slicing rates of UEs with different priorities, and the like, where the slicing rate may be an uplink rate or a downlink rate.

The NWDAF sends an analysis result related to the slicing rate of the UE to the first PCF, the first PCF determines the maximum value of the UE strategy or the slicing rate of the UE according to the analysis result, and sends the maximum value of the UE strategy or the slicing rate of the UE to the AMF, the AMF sends the UE strategy to the UE, and the AMF sends the maximum value of the slicing rate of the UE to the RAN.

The NWDAF sends an analysis result related to the slicing rate of the UE to a second PCF (the same as or different from the first PCF), and the second PCF determines a PCC strategy or an MA PDU session strategy according to the analysis result and sends the strategy to the SMF. When the first and second PCFs are different, both may have previously communicated the analysis.

The NWDAF may also send the analysis result related to the slicing rate of the UE to the OAM or UDM or UDR, which network functions determine the slicing rate of the UE (e.g., the range of the slicing rate of the UE, the maximum value of the slicing rate of the UE, etc.) and then send this information to the PCF.

When the second PCF finds that the slice rate of the UE reaches the maximum value, the second PCF may determine whether the UE has established an MA PDU session for the slice, and if so, the second PCF may implement offloading of part of traffic of the slice to the non-3 GPP access by updating an MA PDU session policy, for example, setting the first priority access as the non-3 GPP access, or setting the activated access as the non-3 GPP access. If the UE does not establish a MA PDU session, the second PCF may send a first request message to the SMF, and the SMF adds a non-3 GPP-accessed connection to the PDU session according to the request message. The second PCF may choose to move low priority data traffic to the non-3 GPP access.

When the second PCF discovers that the slice rate of the UE reaches a maximum value, the second PCF may send a PCC rule to the SMF that reduces the bit rate of the guaranteed bit rate QoS flow.

When the first PCF finds that the slice rate of the UE reaches a maximum, the first PCF decides the UE policy, e.g. sets the preferred access technology for transmitting the slice traffic to a non-3 GPP access, or includes in the UE policy an indication to establish an MA PDU session for the slice.

An event that the slice rate of the UE reaches a maximum value may be communicated between the first PCF and the second PCF.
