  • Patent number: 10750561
    Abstract: The present invention provides a user equipment for use in a cellular network and a method for initiating a radio link abandonment in user equipment in advance of a radio link failure. The present invention includes establishing and maintaining a communication connection between the user equipment and a cellular network via a serving cell base station in support of a data flow via a radio link. The availability of other potential serving cell base stations including the availability of preferred potential serving cell base stations is then monitored. At least one of an uplink condition and a downlink condition of the data flow via the radio link are then monitored. Based upon the determined at least one of the uplink condition and the downlink condition, any impending degradation of the radio link is then predicted. When an impending degradation of the radio link is predicted, and a preferred potential serving cell base station is available, the radio link is abandoned prior to a radio link failure.

  • Patent number: 10021618
    Abstract: A method and apparatus for providing wireless access to a radio access network for a user equipment (UE) obtains, at a server (102), a plurality UE upload cell messages from a plurality UEs (106) served by different cells (402). Each UE upload cell message includes cell specific data and corresponding UE specific data for a specific cell. The method and apparatus aggregate network cell data based at least on the cell specific data and the corresponding UE specific data (404). For example, the method and apparatus may aggregate the cell specific data and the corresponding UE specific data for each serving cell, such that the observances by the UEs are grouped together according to each serving cell. A UE may then receive cell information that is based on the aggregated network cell data (506) to, for example, re-order a scan list or cell roaming list, or bias a cell measurement.

  • Publication number: 20090170498
    Abstract: A method, apparatus, and electronic device for establishing a cellular connection are disclosed. A processor 104 may select a primary telecommunication cell. A primary radio 212 may decode a primary connection parameter for the primary telecommunication cell. The primary radio 212 may execute an initial primary connection attempt with the primary telecommunication cell. The primary radio 212 or a secondary radio 214 may decode a secondary connection parameter for a secondary telecommunication cell prior to a subsequent primary connection attempt.
