The information provided by the embodiments of this application will be discussed below through some embodiments and their application scenarios in conjunction with the accompanying drawings. The information processing method is described in detail.

As shown in Figure 2, the embodiment of the present application provides an information processing method, including the following steps:

Step 201, when the first network function determines that the protocol data unit (Protocol Data Unit, PDU) session of the terminal is not executed according to the first URSP rule, send a URSP rule re-evaluation instruction to the terminal, or send the second network The function sends the detection information of the user plane of the PDU session; wherein, the first URSP rule is a URSP rule configured by the network side device for the terminal, and the URSP rule re-evaluation indication is used to instruct the terminal to perform URSP rule re-evaluation process.

The first network function can detect whether the PDU session of the terminal is executed according to the first URSP rule, and if it is detected that the PDU session of the terminal is not executed according to the first URSP rule, in one implementation, the URSP rule can be sent to the terminal Re-evaluation indication, URSP rule re-evaluation indication includes the identity number (Identity, ID) of the PDU session, instructs the terminal to perform the re-evaluation process of the URSP rule of the PDU session, and the re-evaluation process can make the PDU session of the terminal follow the first URSP rule implement. In another implementation, the first network function sends the detection information of the user plane of the PDU session to the second network function, and the second network function performs the next step of processing based on the detection information, for example, sends the latest URSP rule to the terminal, Or, trigger the terminal to update the URSP rules.

The first network function may be an SMF, and the second network function may be a PCF, for example, a PCF in terms of access management, or a PCF in terms of session management.

The PDU session of the terminal is not executed according to the first URSP rule, which can be understood as one of the following:

(1) The PDU session of the terminal does not match the first URSP rule, that is, the PDU session of the terminal does not execute the first URSP rule, for example, the terminal does not perform the creation and association of the PDU session according to the first URSP rule;

(2) The terminal's PDU session executes the first URSP rule, but the first URSP rule is not correctly executed. For example, the application data of the terminal's PDU session matches the first URSP rule, but the wrong DNN and wrong slice information are selected, Wrong at least one entry in the route descriptor.

(3) The terminal's PDU session executes the first URSP rule, but the first URSP rule is not executed accurately, for example, the application data of the terminal's PDU session matches the first URSP rule, but the terminal At least one of the following is also performed: the application data selects the highest priority routing descriptor; an existing PDU session is selected; lower priority routing descriptors are not evaluated.

In this embodiment, when the first network function determines that the PDU session of the terminal is not executed according to the first URSP rule, it sends a URSP rule re-evaluation indication to the terminal, or sends the user plane of the PDU session to the second network function detection information; wherein, the first URSP rule is a URSP rule configured by a network side device for the terminal, and the URSP rule re-evaluation indication is used to instruct the terminal to perform a URSP rule re-evaluation process.

The PDU session does not correctly execute the first URSP rule, which may include two situations. In one case, the terminal’s PDU session executes the first URSP rule, but the first URSP rule is not correctly executed, for example, the application data of the terminal’s PDU session The first URSP rule is matched, but at least one of the wrong DNN, wrong slice information, and wrong routing descriptor is selected; in another case, the terminal’s PDU session executes the first URSP rule, but the first URSP rule is not accurately executed. A URSP rule, for example, the application data of the PDU session of the terminal matches the first URSP rule, but the terminal also performs at least one of the following: the application data selects the highest priority routing descriptor; selects the existing PDU session; does not compare Low priority route descriptors are evaluated. The third information may indicate the first case or indicate the second case.
