Embodiment 1

[0032] An embodiment of the present invention provides a method for receiving indication information, figure 1 It is a flowchart of a method for receiving indication information according to an embodiment of the present invention, such as figure 1 shown, including:

[0033] Step S102, receiving at least one of the following indication information: the first indication information carried by the policy control function PCF in the policy request response message; the second indication information carried by the PCF in the policy delivery message, wherein the first indication The information is used to notify the UE of receiving the UE routing policy URSP rule, and the second indication information is used to notify the UE that delivery of the URSP rule is completed.

[0034] Through the above steps, at least one of the following indication information is received: the first indication information carried by the policy control function PCF in the policy request response message;...

Embodiment 2

[0045] In this embodiment, a device for receiving indication information is also provided, and the device is used to implement the above embodiments and preferred implementation modes, and what has been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0046] figure 2 is a structural block diagram of a device for receiving indication information according to an embodiment of the present invention, such as figure 2 As shown, the device includes:

[0047] The receiving module 20 is also configured to receive at least one of the following indication information: the first indication information carried by the policy control function PCF in the policy request response m...

Embodiment 3

[0078] Figure 5 It is a schematic flow diagram of the PCF actively initiating a policy update process according to the preferred embodiment 2 of the present invention, such as Figure 5 shown, including:

[0079] In step S701, the PCF detects that the UE policy is updated, and sends a UE policy update notification to the AMF.

[0080] In step S703, the AMF returns a response message to the PCF.

[0081] Step S705, the PCF sends the UE policy to the UE via the AMF. If it is the last UE policy message containing the URSP rule, the PCF carries the last URSP flag in the message and sets it to true, otherwise the last URSP flag is set to false, or Does not carry the last URSP flag.

[0082] In step S707, the UE returns a success message to the PCF via the AMF.

[0083] In steps S709 and S711, when the last URSP flag is true in step S705, the UE matches the service flow with the URSP rule, and selects the matching PDU session for service flow transmission, and initiates the PDU...

Abstract

The invention provides an indication information receiving method and device and a storage medium, and the method comprises the steps: receiving at least one of the following indication information: first indication information carried by a PCF (Policy Control Function) in a policy request response message, wherein the PCF carries second indication information in the strategy issuing message, thefirst indication information is used for notifying the UE to receive a UE routing selection strategy URSP rule, and the second indication information is used for notifying the UE that the URSP rule isissued completely. By adopting the technical scheme, the problem that the established or selected PDU session is inappropriate due to the fact that the UE directly establishes the PDU session or selects the existing session for the service flow before the UE does not receive the URSP rule or does not completely receive the URSP rule in the prior art is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for receiving indication information, and a storage medium. Background technique [0002] User Equipment (referred to as UE for short) registration process: UE initiates registration to Access and Mobility Management Function (Access and Mobility Management Function, referred to as AMF for short), AMF returns a registration acceptance response, and at the same time registers with the Policy Control Function (Policy Control Function) Function, PCF for short) requests UE policy. [0003] The UE policy issued by the PCF includes UE Route Selection Policy (UE Route Selection Policy, URSP for short) rules. The UE selects a suitable PDU session for the service flow according to the URSP rule. If there is no suitable PDU session, a new PDU session is created. [0004] The following application scenarios exist in related technologies: (1) UE initiates the establish...
