example 1

[0234] Example 1, such as Figure 10 shown, including the following steps:

[0235] Step 1001, when network slice 1 is congested, SMF1 sends slice congestion information to AMF to notify AMF that current network slice 1 is congested, and triggers AMF to start the following congestion control mechanism.

[0236] Step 1002, the user terminal sends a PDU session establishment request (PDU SessionEstablishmentRequest) to request the network to establish a PDU connection provided by the slice S-NSSAI_1 to the data network DDN3, and the request includes S-NSSAI_1 and DDN3.

[0237] Step 1003, the AMF judges that the slice S-NSSAI_1 is in a congested state, and the AMF sends a PDU session establishment rejection (PDUSession Establishment reject) message to the user terminal, and the message carries cause value: slice congestion, and the value of the backoff timer corresponding to the network slice.

[0238] Step 1004, the user terminal takes a corresponding backoff action according to...

example 2

[0246] Example 2, such as Figure 11 shown, including the following steps:

[0247] Step 1101, when network slice 1 is congested, SMF1 sends slice congestion information to AMF to inform AMF that current network slice 1 is congested, and triggers AMF to start the following congestion control mechanism.

[0248] Step 1102, the UE sends a PDU Session modification Request (PDU Session modificationRequest) (including S-NSSAI_1, PDU session ID1) message to the network to request modification to PDUsession 1 of slice S-NSSAI_1.

[0249] Step 1103, the AMF judges that the slice S-NSSAI_1 is in a congested state, and the AMF sends a PDU session modification reject (PDUSession modification reject) message to the user terminal, and the message carries cause value: slice congestion, and the value of the back-off timer corresponding to the network slice;

[0250] Step 1104, the user terminal takes a corresponding backoff action according to the rejection message.

[0251] Among them, if...

example 3

[0258] Example 3, such as Figure 12 shown, including the following steps:

[0259] Step 1201, when slice1 is congested, SMF1 sends slice congestion information to AMF to inform AMF that current slice1 is congested, and triggers AMF to start the following congestion control mechanism.

[0260] Step 1202, AMF sends a PDU session release command (PDU Session releaseet command) message to UE, the message carries cause value: slice congestion, and the value of the backoff timer corresponding to the network slice.

[0261] Step 1203, the user terminal takes a corresponding backoff action according to the rejection message.

[0262] Among them, if there is a slice backoff timer corresponding to S-NSSAI_1 running, the user terminal first stops the timer, and performs the following actions:

[0263] If the value of the backoff timer provided by the AMF is not 0 or not deactive, the user terminal sets the value of the slice backoff timer to the value of the backoff timer provided by ...

Abstract

Embodiments of the present invention provide a method, related equipment, and system for dealing with network slice congestion. The method includes: receiving a message containing slice congestion information sent by the network; The target network slice adopts backoff behavior. The embodiment of the present invention deals with the network slice congestion, which can avoid the aggravation of the network slice congestion, and further improve the overall performance of the communication system.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, related equipment and system for dealing with network slice congestion. Background technique [0002] As a core technology of future communication systems (such as 5G systems), network slicing allows operators to flexibly and dynamically provide various types of virtual network services on the same network infrastructure. [0003] Since the resources of different network slices in the network are independent, different network slices may be in different congestion situations. Services can be provided normally, and the access of the user terminal to the network slice 1 will lead to aggravation of network slice congestion. Contents of the invention [0004] Embodiments of the present invention provide a method, related equipment, and system for dealing with network slice congestion, so as to solve the technical problem of aggravated network slice con...
