Method and apparatus for LTE handover reduction

摘要

A method of setting hand over (HO) parameters for a user equipment (UE) connected to a first cell of a base station (BS) may include receiving, at the BS, history data corresponding to the UE, the history data including, for each of a plurality of cells the UE was previously connected to, an entry including HO information of the UE at the cell; determining at the BS, an activity type of the UE based on the received history data; and setting, at the BS, the HO parameters for the UE based on the determined activity type, the HO parameters controlling the manner in which the UE detects conditions for initiating an HO event.

1. A method of setting hand over (HO) parameters for a user equipment (UE) connected to a first cell of a base station (BS), the method comprising:
receiving, at the BS, history data corresponding to the UE, the history data including, for one or more cells the UE was previously connected to, at least one entry including HO information of the UE at a respective one of the one or more cells; determining at the BS, an activity type of the UE, from among a plurality of activity types, based on the history data, the plurality of activity types including one or more high speed activity types and one or more low speed activity types, the history data indicating a total number of different cells visited by the UE in a reference amount of time, the determining including determining the activity type of the UE to be one of the one or more high speed activity types or one of the one or more low speed activity types based on the indicated total number of different cells visited by the UE in a reference amount of time; and setting, at the BS, the HO parameters for the UE based on the determined activity type, the HO parameters controlling the manner in which the UE detects conditions for initiating an HO event, wherein when the activity type of the UE is determined to be one of the one or more low speed activity types,
the determining an activity type of the UE further includes,
when the indicated total number of different cells visited by the UE in the reference amount of time is below a reference value, determining a location of the UE to be near a center of a cell, andwhen the indicated total number of different cells visited by the UE in the reference amount of time is at or above a reference value, determining a location of the UE to be near a border of a cell, andthe setting the HO parameters further includes setting the HO parameters based on the determined location of the UE.
