First Claim
Patent Images
1. A method of wireless communication in a TD-SCDMA system, comprising:
- determining to perform a handover from a source cell to a target cell;
establishing a link with the target cell while maintaining a call with the source cell;
terminating a link corresponding to the call with the source cell after the link with the target cell is established; and
continuing the call utilizing the established link with the target cell.

Abstract
A system and method enable make-before-break handover from a source cell to a target cell in a TD-SCDMA system. According to various aspects of the present disclosure, a wireless link is established with the target cell while maintaining the call with the source cell. The communication between the mobile station and the respective source and target cells may be multiplexed utilizing time division multiplexing or frequency division multiplexing. When utilizing time division multiplexing, the allocation between the respective source and target cells may be made slot-by-slot in a subframe, or subframe-by-subframe in a radio frame.
