Telecommunication system and operating method
First Claim
1. A method configured for reducing handover in a telecommunication system, the method comprising:
- providing a plurality of cells;
providing a base station and at least one relay station in each of the plurality of cells, each of the at least one relay station being configured to provide a multi-hop relay function;
determining that a mobile station moves from a first cell toward a second cell of the plurality of cells, the first cell and the second cell overlapping one another in an overlap region;
determining whether there is a second relay station in the overlap region provided in the second cell in a moving path when the mobile station moves from a first relay station provided in the first cell into the overlap region;
providing communication service to the mobile station by a first station and the first relay station provided in the first cell in the absence of the second relay station in the overlap region in the moving path; and
providing communication service to the mobile station by the first station provided in the first cell and the second relay station provided in the second cell in the presence of the second relay station in the overlap region in the moving path.

Abstract
A telecommunication system includes a first cell and a second cell overlapping one another in an overlap region, a first base station in the first cell, a second base station in the second cell, a first relay station configured to provide a multi-hop relay function between the first base station and a first point in the overlap region closer to the second base station than the first base station, and a second relay station configured to provide a multi-hop relay function between the second base station and a second point in the overlap region closer to the first base station than the second base station, wherein the first base station and the first relay station in the first cell provide communication service to the mobile station till the mobile station moves to the first point in the overlap region.

15. A method configured for reducing handover in a telecommunication system, the method comprising:
-
providing a plurality of cells; providing a base station and at least one relay station in each of the plurality of cells; providing each of the at least one relay station with a first transceiver for communication with a first base station and a second transceiver for communication with a second base station; determining that a mobile station moves from a first cell toward a second cell of the plurality of cells, the first cell and the second cell overlapping one another in an overlap region; and maintaining communication between the first base station and the mobile station till the mobile station moves away from the first cell. - View Dependent Claims (16, 17, 18, 19)
