Abstract
A method for handling IMS registrations at a P-CSCF after PCRF database failure includes receiving a SIP REGISTER request message after a PCRF database failure and determining that the SIP REGISTER request message is for an existing user. The method further includes obtaining a list of user contacts having entries in a registration cache of the P-CSCF corresponding to an address of record in the SIP REGISTER request message, testing reachability of the user contacts in the list, and freeing resources of the P-CSCF for the user contacts determined to be unreachable.
