  • Patent number: 10412128
    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).

  • Patent number: 10277384
    Abstract: Embodiments herein describe using an intermediate distribution frame (IDF) which is connected between a central controller and a plurality radio heads which each include at least one antenna for wireless communication with a user device. Instead of running separate cables to each of the radio heads, a single cable can be used to connect the IDF to the central controller and then separate cables can be used to connect the IDF to the radio heads. If the IDF is disposed near the radio heads, the amount of cables can be reduced. Moreover, the IDF may recover a clock signal used by the central controller and forward that clock to the plurality of radio head in order to synchronize the radio heads to the central controller.
