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 1):
A computer-implemented method for use in a mobile telecommunications network to manage security associations in a mobile device for Internet Protocol Multimedia Subsystem (IMS) services, the method comprising:\n registering the mobile device to receive one or more IMS services via the mobile telecommunications network,\n wherein the registering includes negotiating a first pair of security associations that enable the mobile device to receive the one or more IMS services, and \n wherein the first pair of security associations includes an expiration time after which the first pair of security associations are no longer valid; \n storing the negotiated first pair of security associations; receiving, via the mobile telecommunications network, a request for at least one IMS service; permitting access to the at least one IMS service based at least in part on the stored first pair of security associations; re-registering the mobile device to receive one or more IMS services via the mobile telecommunications network,\n wherein the re-registering includes negotiating a second pair of security associations that enable the mobile device to receive the one or more IMS services, and \n wherein the second pair of security associations includes an expiration time after which the second pair of security associations are no longer valid; \n storing the negotiated second pair of security associations; deleting the negotiated first pair of security associations stored on the mobile telecommunication network; receiving, via the mobile telecommunications network, a request for another of the one or more IMS services; and permitting access to the other IMS service based at least in part on the stored second pair of security associations.
