Communication terminal and method for performing a cell search
First Claim
1. A communication terminal comprising:
- a determiner configured to determine cell search control information including at least one of a radio access technology (RAT) to be searched for, a search duration, a number of search iterations, or a number of antennas to be used for the search based on information about radio conditions at a position of the communication terminal and historical information about presence of radio cells at the position of the communication terminal, wherein the historical information about presence of radio cells comprises information about radio cells to which the communication terminal has previously connected at the position of the communication terminal; and
a transceiver, coupled to the determiner, and configured to perform a cell search based on the determined cell search control information to identify a radio cell of the RAT to be searched for, and to cause the communication terminal to move a connection from a previous radio cell of a previous RAT to the radio cell of the RAT to be searched for.

Abstract
According to an example, a communication terminal is described comprising a determiner configured to determine cell search control information including at least a radio access technology to be searched for, a search duration, a number of search iterations, a number of antennas to be used for the search and based on at least one of information about the current radio conditions that the communication terminal is experiencing, position of the terminal, historical information about the presence of the radio cells at the position of the communication terminal, communication terminal attach history in terms of moving from some specific RATs/cells to other specific RATs/cells, proximity sensors'"'"' information and a transceiver configured to perform a cell search based on the determined cell search control information.

18. A method for performing a cell search comprising:
-
determining cell search control information including at least one of a radio access technology (RAT) to be searched for, a search duration, a number of search iterations, or a number of antennas to be used for the search based on information about radio conditions at a position of a communication terminal and historical information about presence of radio cells at the position of the communication terminal, wherein the historical information about presence of radio cells comprises information about radio cells to which the communication terminal has previously connected at the position of the communication terminal; performing a cell search based on the determined cell search control information to identify a radio cell of the RAT to be searched for; and causing the communication terminal to move a connection from a previous radio cell of a previous RAT to the radio cell of the RAT to be searched for.

19. A non-transitory computer readable storage medium having recorded instructions thereon which, when executed by a processor, cause the processor to:
-
determine cell search control information including at least one of a radio access technology (RAT) to be searched for, a search duration, a number of search iterations, or a number of antennas to be used for the search based on information about radio conditions at a position of a communication terminal and historical information about presence of radio cells at the position of the communication terminal, wherein the historical information about presence of radio cells comprises information about radio cells to which the communication terminal has previously connected at the position of the communication terminal; perform a cell search based on the determined cell search control information to identify a radio cell of the RAT to be searched for; and cause the communication terminal to move a connection from a previous radio cell of a previous RAT to the radio cell of the RAT to be searched for.

20. A communication terminal comprising:
-
a determiner configured to determine cell search control information corresponding to a cell search, the cell search control information including a number of antennas to be used for the cell search based on at least one of information about radio conditions at a position of the communication terminal or historical information about presence of radio cells at the position of the communication terminal, wherein the determiner is configured to set the number of antennas to be used for the cell search to a single antenna if a reception strength at the communication terminal is above a first predetermined threshold and to set the number of antennas to be used for the cell search to multiple antennas if the reception strength is below the first predetermined threshold; and a transceiver, coupled to the determiner, and configured to perform the cell search based on the determined cell search control information to identify a radio cell of a second radio access technology (RAT), and to cause the communication terminal to move a connection from a previous radio cell of a first RAT to the radio cell of the second RAT.
