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 1):
An apparatus, comprising:\n at least one memory; and logic for a proxy call session control function (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:\n receive a session initiation protocol (SIP) INVITE message from roaming user equipment (UE), the SIP INVITE message associated with an attempt to place an emergency call via an unauthenticated internet protocol multimedia subsystem (IMS) session; \n obtain a public safety answering point (PSAP) callback number for the UE from a policy and charging rules function (PCRF) node via an Rx interface; \n identify a PSAP callback parameter for the UE based on the PSAP callback number; \n insert the PSAP callback parameter into the SIP INVITE message; and \n forward the SIP INVITE message to a PSAP.
