Methods, systems, and computer readable media for sharing identification information of network nodes in an IMS network are disclosed. One method includes determining, by a packet data network gateway (PGW), policy and charging rules function (PCRF) identification information corresponding to a PCRF node designated to support an IMS-based subscriber session requested by a user equipment device and establishing, by the PGW, a subscriber Gx session with the PCRF node corresponding to the determined PCRF identification information. The method further includes determining, by the PGW, application function (AF) identification information corresponding to an AF server designated to support the IMS-based subscriber session and generating, by the PGW, a create session response message including at least the PCRF identification information and the AF identification information. The method also includes sending, by the PGW, the create session response message containing the at least the PCRF identification inform.
