Patent number: 9608860Abstract: Example implementations are directed to systems and methods involving a mobility management entity (MME) pool. In example implementations, the MME of the pool can be configured as a backup for a fraction of subscribers associated with other MME in the pool. Upon detection of the failure of an MME in the pool, the surviving MME messages eNodeBs and other peer network nodes that it will take over the impacted subscribers such that the subscribers do not need to conduct a reattachment process. Multiple MME codes per MME can be used to partition the subscribers for backup, which can thereby lead to geo-redundancy for the MME.Type: GrantFiled: March 28, 2016Date of Patent: March 28, 2017Assignee: AFFIRMED NETWORKS COMMUNICATIONS TECHNOLOGIES, INC.Inventors: Haibo Qian, Fred Rink, Michael Brown

Patent number: 8004459Abstract: Embodiments provide systems and methods for determining the geolocation of an emitter on earth. A solution is obtained from two TDOA measurements that need not be acquired at the same time.

Determining a geolocation solution of an emitter on earth based on weighted least-squares estimation
Patent number: 7663547Abstract: Embodiments provide systems and methods for determining the geolocation of an emitter on earth based on weighted least-squares estimation based on two TDOA and two FDOA measurements, none of which need to be acquired at the same time. The four TDOA and FDOA measurements and the errors in each of the measurements are determined. Weights for the errors in the TDOA and FDOA measurements are determined, and the weights are applied in a weighted errors function. The weights account for the errors in the measurements and the errors in the satellite positions and velocities, and are dependent on the localization geometry. The weighted errors function is minimized to determine the location estimate of the unknown emitter.Type: GrantFiled: April 13, 2007Date of Patent: February 16, 2010Assignee: Glowlink Communications Technology, Inc.Inventors: Dominic K.
