Patent number: 11012894Abstract: In an example method, a base station determines that a UE is CSFB capable and that the base station is currently serving a relay on a first carrier of a plurality of carriers. The base station provides a coverage area on which to serve UEs, and the coverage area operates on the plurality of carriers. Based on at least the determining that the UE is CSFB capable and that the base station is currently serving the relay on the first carrier, the base station assigns the UE to operate on a carrier of the plurality of carriers other than the first carrier rather than having the UE operate on the first carrier on which the base station is currently serving the relay.Type: GrantFiled: November 9, 2018Date of Patent: May 18, 2021Assignee: Sprint Spectrum L.P.Inventors: Siddharth S.

Patent number: 10764933Abstract: A system and method is provided for a predictive connectivity layer. In the disclosed embodiments, resources, such as bandwidth, processing, and memory, at a network node are dynamically allocated based on one or more predicted user behaviors. A predicted user behavior may be determined based on one or more previous actions of a user or a group of users at the network node. For example, if a user accesses the network node to download a particular web site at the same time every morning, the predictive technique may determine that the user will attempt to download the same web site the next morning, and therefore cache a copy of the web site before the user's next attempt to access the network through the network node. Similarly, the network node may predict an amount of bandwidth or other resources to allocate based on previous behavior of one or more users.Type: GrantFiled: May 9, 2016Date of Patent: September 1, 2020Assignee: Federated Wireless, Inc.Inventors: Sepehr Mehrabanzad, Iyad Tarazi, Deepak Das
