Embodiments of the present invention provide a method, an apparatus, and a system for determining a policy and charging rule function entity. The method for determining the policy and charging rule function entity 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, by the first PCRF, 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, by the first PCRF, a message carrying the identity of the second PCRF to the first routing agent device, so that the first routing agent device transmits the first request message to the second PCRF according to the identity of the second PCRF. The method for determining the PCRF in embodiments of the present invention can route sessions of the same user to the same RCPF, thereby solving a problem and realizing 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 providing reliable DRA signaling network networking. |
