Abstract:
IMS emergency call routing techniques are described. In one embodiment, for example, an apparatus may comprise at least one memory and logic for a P-CSCF node, at least a portion of the logic comprised in circuitry coupled to the at least one memory, the logic to cause the P-CSCF node to receive an SIP INVITE message from a roaming UE, the SIP INVITE message associated with an attempt to place an emergency call via an unauthenticated IMS session, the logic to cause the P-CSCF node to obtain a PSAP callback number for the UE from a PCRF node via an Rx interface, identify a PSAP callback parameter for the UE based on the PSAP callback number, insert the PSAP callback parameter into the SIP INVITE message, and forward the SIP INVITE message to a PSAP. Other embodiments are described and claimed.

Claim (Index 13):
The at least one computer-readable storage medium of  claim 12 , comprising instructions that, in response to being executed at the P-CSCF node, cause the P-CSCF node to:\n send a Diameter protocol AA-Request message to the PCRF node to initiate an Rx session establishment procedure; and receive a Diameter protocol AA-Answer message from the PCRF node, the Diameter protocol AA-Answer message to comprise the PSAP callback number for the UE.
