  • Cell Selection Method and Apparatus
    Publication number: 20230051540
    Abstract: Embodiments of this application provide a cell selection method and an apparatus, and relate to the communications field. A terminal may determine a first measurement frequency and a 5G anchor cell at the first measurement frequency based on prior historical information. The terminal may shorten evaluation duration corresponding to a 5G anchor cell that meets a preferred condition at a first measurement frequency, so as to improve a probability that the terminal camps on the 5G anchor cell.

  • METHOD AND APPARATUS FOR CONTROLLING MAP-SIDE AGGREGATION OF USER TASK IN A MAPREDUCE COMPUTING PLATFORM
    Publication number: 20190026327
    Abstract: The present disclosure relates to a method and apparatus for controlling map-side aggregation of a user task in a MapReduce (MR) computing platform. The method for controlling map-side aggregation of a user task in an MR computing platform includes: receiving a submitted user task; detecting whether the received user task satisfies a preset map-side aggregation enabling condition; and controlling, according to a result of the detection, whether map-side aggregation of the user task is to be enabled.
