Abstract:
Managing Security Parameter Information (SPIs) to prevent race condition failures begins where a system negotiates SPIs along with associated expiration times, and re-negotiates new SPIs as necessary. The system prevents race conditions that would otherwise occur when both an old SPI and a new SPI are active at the same time. The system accomplishes this by managing the storage and deletion of old SPIs such that only active SPIs are stored on the system for use by a User Equipment (UE) or Proxy Call Session Control Function (P-CSCF).

Claim (Index 14):
A mobile device adapted to manage security parameters that enable the mobile device to receive Internet Protocol Multimedia Subsystem (IMS) services via a mobile telecommunications network, the mobile device comprising:\n an input device; an output device; memory storing programmed instructions; a processor coupled to the memory, input device and output device, wherein the processor is configured to execute the programmed instructions to perform operations including:\n requesting registration of the mobile device to receive one or more IMS services via the mobile telecommunications network; negotiating a first pair of security associations that includes an expiration time; \n storing the first pair of negotiated security associations; \n receiving a request for an IMS service; \n permitting access to the requested IMS service based at least in part on the stored first pair of security associations; \n requesting re-registration of the mobile device to receive one or more IMS services via the mobile telecommunications network; \n negotiating a second pair of security associations that includes an expiration time; \n storing the second pair of negotiated security associations; \n deleting the first pair of negotiated security associations; \n receiving a request for another of the one or more IMS services; and \n permitting access to the other IMS service based at least in part on the stored second pair of security associations.
