Embodiments of the present invention provide a method, an apparatus, and a system for determining a policy and charging rule function entity. The method includes: receiving, by a first PCRF, a first request message transmitted by a first routing agent device, where the first request message carries an IP address of a user; inquiring a pre-stored corresponding relationship between the IP address of the user and an identity of a PCRF currently serving the user according to the IP address of the user, and determining an identity of a second PCRF currently serving the user; and transmitting a message carrying the identity of the second PCRF to the first routing agent device. The method realizes that session information of the same user can be routed to the same PCRF when a biplane DRA is under a multi-PCRF networking, and provides reliable DRA signaling network networking.

Method, apparatus and system for determining policy and charging rule function entity

A method for detecting a message loop, a routing agent apparatus, and a networking system. The method for detecting a message loop includes: receiving a request message sent by a network element apparatus; acquiring routing information for sending the request message to a server apparatus; detecting whether a next-hop link for sending the request message in the routing information and a link for receiving the request message belong to a same link set; and sending a response to the network element apparatus that a message loop is detected, when it is detected that the link for sending the request message in the routing information and the link for receiving the request message belong to a same link set. The technical solutions disclosed herein can improve the efficiency of detecting the message loop and thus have strong practicability.
