Abstract:
A user device registers with a proxy-call session control function device (P-CSCF) associated with an Internet protocol (IP) multimedia subsystem (IMS). The user device forwards a request to the P-CSCF requesting a session via the IMS for an IMS call. If a response to the request is not received from the P-CSCF during a time period after forwarding the request, the user device attempts to newly register with the P-CSCF. If the new registration is successful, the user device re-forwards the request to the P-CSCF. Otherwise, if the new registration with the P-CSCF is unsuccessful, the user device registers with a different P-CSCF and forwards the request to the second P-CSCF.

Claim (Index 1):
A method comprising:\n forwarding, by a processor associated with a user device, a registration request to an Internet protocol (IP) multimedia subsystem (IMS) to assign the user device to a proxy-call session control function device (P-CSCF) associated with the IMS; receiving, at the processor, information identifying a plurality of P-CSCFs including the P-CSCF; forwarding, by the processor, a message to the P-CSCF requesting a session via the IMS for an IMS call; determining, by the processor, that a response to the message is not received from the P-CSCF during a particular time period; registering, by the processor and based on determining that the response is not received during the particular time period, the user device with a second P-CSCF of the plurality of P-CSCFs; and sending, by the processor, the message to the second P-CSCF based on registering the user device with the second P-CSCF.
