Description

Slice information processing method, system, related network equipment and storage medium

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a slice information processing method, system, related network device, and storage medium.

Background

A User Equipment (UE) routing Policy (URSP) is used for UE routing Policy Selection. At present, when a slice subscription is opened, a user generates user URSP Data including slice information through a Business Operation Support System (BOSS), writes the user URSP Data into a Policy Control Function (PCF), a Unified Data Repository (UDR), and issues the user URSP Data to a UE in a slice Business process, so as to assist the UE in placing correct Business on a proper slice for bearing.

On the other hand, this method is used for writing the URSP data into the network through the BOSS, and when the user desires to adjust, the user must make a service subscription change through the BOSS again, which results in long change period and low efficiency. Moreover, when a user changes a service subscription, professional knowledge such as URSP and slicing needs to be known, which requires a high demand for the user. On the other hand, the URSP adopts a static pre-write mode, and cannot perform slice adjustment according to the service quality condition actually used by the user.

Step 614: and the UE selects the slice according to the URSP data and initiates the service by using the selected slice.

Example two

FIG. 7 is a schematic interaction flow diagram of a slice information processing method according to an embodiment of the present invention; the example is that URSP is issued according to the service quality measurement result for non-specified users so as to realize slice selection. This example is made on the premise that the UE has established a session with the application node. As shown in fig. 7, the method includes:

step 701: the application node issues a service measurement request to the NEF and receives a response message fed back by the NEF. Wherein the service measurement request includes service measurement data, and the service measurement data includes: the service application may include information such as an application identifier, a measurement indicator category (which may include packet loss rate, delay, jitter, bandwidth, and the like, for example), a measurement type (which may include 1 measurement, multiple measurements, or periodic measurements, for example), a measurement time period, and a service application address list.

The service measurement data is also the measurement information in the above embodiment.

Step 702: the NEF generates service measurement content (for example, the service measurement content can include an application destination address, a measurement result notification address, a measurement index category, a measurement type, a measurement interface (such as N3 and N6 interfaces), a measurement time period, associated slice information, Protocol Data Unit (PDU) session information, a related user identifier and the like) according to the received service measurement Data, allocates a measurement identifier to be associated with information such as an application identifier, a measurement timestamp and the like, supports issuing a service interface quality measurement request (NEF _ ServiceInfQoSMeasure) message to the SMF, and the service interface quality measurement request message carries information such as the measurement identifier and the service measurement content; and receiving a response message fed back by the SMF.

The service measurement content is also the first relevant information about the service interface quality measurement of the user equipment in the above embodiment.

Step 703: after receiving the service interface quality measurement request message, the SMF records the NEF address, the measurement identifier and other information, and issues a user plane service interface quality measurement request (SMF _ UInfQoSMeasure) message to the UPF, where the user plane service interface quality measurement request message carries the user plane service quality measurement content (which may include an application destination address, a measurement index type, a measurement interface (N3, N6 interface), a measurement time period, associated PDU session information, etc.), the measurement identifier, the measurement result notification address and other information.

The content of the service quality measurement of the user plane is also the second related information used for indicating the UPF to perform the service interface quality measurement of the user plane in the above embodiment.

Step 704: and after receiving the user plane service interface quality measurement request message, the UPF performs user plane service interface quality measurement.

Specifically, the UPF detects whether a corresponding PDU session exists according to a service application address (IP address or URL) list, acquires a source address (i.e., the address of the UE) for establishing the PDU session if it is detected that the PDU session has been established between the UE and the application node, detects whether information such as a corresponding service flow IP transmission/reception packet exists, starts to measure, according to a measurement interface specified by measurement content, an N3 interface, an N6 interface, or an N3 interface + an N6 interface according to a measurement index type, a measurement type, and a measurement time period requirement in the measurement content, indexes such as bandwidth, delay, packet loss, jitter, and the like of a specified service data flow, and sets a measurement timer according to a measurement duration.

And for the measurement of a plurality of interfaces, reporting the quality measurement results of the plurality of interfaces is supported.

After receiving the service measurement result, the SMF acquires information such as slice identification and user identification associated with the PDU session according to the PDU session information and the UE address information, and combines the measurement results of multiple interfaces. According to the measurement result, the address is informed to send a service interface quality measurement result (smf _ servicelnfQoSMeasure) message to the NEF; the service interface quality measurement result message may include a service flow measurement result, and the service flow measurement result may include a measurement identifier, associated slice information, a user identifier, PDU session information, an application destination address, a UE source address, an actual measurement duration, a measurement interface, a measurement indicator type (e.g., bandwidth, delay, packet loss, and jitter), a measurement indicator value, a measurement state (e.g., measurement is in progress, measurement is completed, and measurement is abnormal), and the like.

Step 706: after receiving the service flow measurement result, the NEF sends the service flow measurement result to the application, where the service flow measurement result includes information such as an application identifier, associated slice information, a related user identifier, an application destination address, PDU session information, a UE source address, an actual measurement duration, a measurement interface, a measurement indicator type (e.g., bandwidth, delay, packet loss, and jitter), a measurement indicator value, and a measurement state (e.g., during measurement execution, measurement end, and measurement abnormality).

Step 708: and the application node issues a service reselection slice instruction according to the service flow measurement result, the URSP detection result and the SLA analysis of the user.

The service reselection slice indication is also the slice change indication in the foregoing embodiment.

Step 709: the NEF constructs URSP data based on the service flow quality measurement result (such as associated slice information, user identification and the like) according to the received service reselection slice indication, and sends the URSP data to the PCF to which the UE belongs; the PCF sends the URSP data to the UE via the AMF.
