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.

Abstract: Embodiments of user equipment and a method for network access selection based on IMS service are generally described herein. In some embodiments, the method includes a UE receiving a message from an ANDSF server comprising an ANDSF MO that includes an inter-system routing policy (ISRP) based on an Internet Protocol (IP) Multimedia Subsystem (IMS) service identifier. The UE may then offload IMS traffic from the cellular network to a non-cellular network based on the IMS service identifier and the ISRP.

Abstract: A fast high-density data compression circuit adapted to semiconductor integrated circuits of the memory type including an ABIST unit. This circuit, which compares the data-out signals output by the memory unit with the expected data generated by the ABIST unit to deliver a signal on a cycle by cycle basis, which is indicative of the fail/no fail status of the memory unit.
