Method and system for identifying application detection and control function mode

摘要

A method for identifying an Application Detection Control (ADC) function mode is disclosed. The method is applicable to a scenario where a roaming UE accesses a visited network from a visited location, and includes that: when a Visit Policy And Charging Rule Function entity (V-PCRF) creates an S9 session, the V-PCRF informs a Home Policy And Charging Rule Function entity (H-PCRF) of an ADC (ADC) function mode supported by a visited network; and the H-PCRF determines, in accordance with the ADC function mode supported by the visited network, whether to provide the ADC rule to the visited network. A system for identifying an ADC function mode is disclosed. With the method and the system, when a user is in a visited access scenario, a network system can perform a correct application detection function on the user.

1. A method for identifying an Application Detection Control (ADC) function mode, the method being applicable to a scenario where a roaming UE accesses a visited network from a visited location, the method comprising:
when a Visit Policy and Charging Rules Function (V-PCRF) creates an S9 session, informing, by the V-PCRF, a Home Policy and Charging Rules Function (H-PCRF) of an ADC function mode supported by the visited network; and determining, by the H-PCRF, whether to provide an ADC rule to the visited network in accordance with the ADC function mode supported by the visited network, wherein the ADC function mode is one of a solicited application reporting mode and an unsolicited application reporting mode; wherein when the visited network supports the solicited application reporting mode, (i) informing, by the V-PCRF, through an S9 session establishment indication message the H-PCRF that the visited network supports the solicited application reporting ADC function mode; and (ii) sending, by the H-PCRF, the ADC rule to the V-PCRF through an S9 session establishment acknowledgement message; and wherein when the visited network supports the unsolicited application reporting mode, (i) informing, by the V-PCRF, through an S9 session establishment indication message the H-PCRF that the visited network supports the unsolicited application reporting ADC function; and (ii) sending, by the H-PCRF, an S9 session establishment acknowledgement message including no ADC rule to the V-PCRF.
