US 2022/0191765 A1 · COMMUNICATION METHOD, APPARATUS, AND SYSTEM

Abstract

In a communication method, a policy control network element receives first information from a terminal device, where the first information is a banned application identifier, a banned PSI, a URSP identifier, or an allowed application identifier. The policy control network element obtains a first URSP of the terminal device from a data storage network element. The policy control network element determines a second URSP of the terminal device based on the first information and the first URSP. Based on this solution, when deciding a URSP of the terminal device, the policy control network element considers the first information reported by the terminal device, so that a proper URSP can be determined for the terminal device. In addition, this helps avoid signaling overheads caused because the terminal device and a policy control network element side continuously update and maintain a URSP that the terminal device does not need to use.

Dependent claims

A communication method, comprising:

receiving, by a policy control network element, first information from a terminal device, wherein the first information is a banned application identifier, a banned policy section identifier (PSI), a banned user route selection policy (URSP) identifier, or an allowed application identifier;
obtaining, by the policy control network element, a first URSP of the terminal device from a data storage network element;
and
determining, by the policy control network element, a second URSP of the terminal device based on the first information and the first URSP.

1 more element

A communication apparatus, comprising:

at least one processor;
and
a memory storing executable instructions;
the processor being configured to execute the executable instructions to:
receive first information from a terminal device, wherein the first information is a banned application identifier, a banned policy section identifier (PSI), a banned user route selection policy (URSP) identifier, or an allowed application identifier, and obtain a first URSP of the terminal device from a data storage network element;
