METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR POLICY CHARGING AND RULES FUNCTION (PCRF) NODE SELECTION
First Claim
1. A system for a policy charging and rules function (PCRF) node selection, the system comprising:
- a first PCRF selection node for receiving a first request message for which PCRF node selection is required, for determining whether to select a PCRF node or to delegate selection of the PCRF node, and, in response to determining to delegate selection of the PCRF node, for generating and sending a second request message based on the first request message; and
a second PCRF selection node for, in response to receiving the second request message from the first PCRF selection node, for determining whether to select the PCRF node, and, in response to determining to select the PCRF node, for selecting the PCRF node.

Abstract
The subject matter described herein includes methods, systems, and computer readable media for PCRF node selection. According to one aspect, a system for PCRF node selection is provided. The system includes a first PCRF selection node for receiving a first request message for which PCRF node selection is required. The first PCRF selection node determines whether to select the PCRF or to delegate selection of the PCRF. In response to a determination to delegate the selection of the PCRF, the first PCRF selection node generates and sends a second request message related to the first request message. The system further includes a second PCRF node for, in response to receiving the second request message from the first PCRF selection node, determining whether to select the PCRF or to delegate selection of the PCRF. In response to determining to select the PCRF, the second PCRF selection node selects the PCRF.
