Inventor: LU QIANXI
IPC: H04W84/06
Filed: 2019-10-10
Abstract: The present application discloses an ephemeris information-based serving cell reselection method and apparatus, and a storage medium. Said method comprises: acquiring satellite ephemeris information, and determining, according to the satellite ephemeris information, at least one adjacent cell of the current serving cell; and when it is detected that serving cell reselection is required, selecting a first target serving cell from the at least one adjacent cell, so as to perform cell reselection. The solution utilizes the properties of the satellite ephemeris information, i.e. being able to be used for accurately calculating, predicting, depicting and tracking the operation state, such as the time, position and speed, of a satellite/flight object, to determine a satellite currently or subsequently serving a serving cell, so as to further determine at least one adjacent cell of the current serving cell, and even in cases where the satellite moves at a high speed and the network topology changes rapidly,can ensure that when a cell reselection is required at a user terminal, a cell reselected from adjacent cells can effectively provide good communication services to the user terminal and avoid unnecessary cell reselection.
