Problems solved by technology

[0012] That is, in the conventional hand-off method, operations of transmitting data and searching for adjacent base stations are repeated until an adjacent base station to which the terminal is to be handed off is detected, which wastes protection required in switching transmission / reception modes. time
The waste of this guard time will reduce the actual search time for the terminal to search for neighboring base stations
In addition, the frequency rate mode conversion increases the load on the base station and terminal

Embodiment Construction

[0031] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would unnecessarily obscure the invention.

[0032] In the mobile communication system according to the present invention, the base station apparatus has consecutive first and second frames each divided into a first interval and a second interval following the first interval, and in the first interval and the second interval of the first frame The frame data is transmitted in the second interval of the two frames, and the transmission of the frame data is stopped in the second interval of the first frame and the first interval of the second frame. In addition, the terminal device receives and processes the transmitted frame data during the first interval of the first frame and the second interval of the second frame, receives data from other The signal o...

Abstract

A mobile communication system transmitting data in frame unit includes a base station apparatus and a terminal apparatus. The transmitter comprises a controller having consecutive first and second frames each divided into a first interval and a second interval following the first interval. In a handoff mode, the controller transmits respective frame data in the first interval of the first frame and the second interval of the second frame and stops transmission of the data in the second interval of the first frame and the first interval of the second frame. Further, the terminal apparatus comprises a receiver for processing received data, a handoff determiner for determining a handoff target base station by analyzing a strength of the received signal, and a controller applying to the receiver a signal transmitted from a present base station in the first interval of the first frame and the second interval of the second frame and applying to the handoff determiner signals transmitted from other base stations in the second interval of the first frame and the first interval of the second frame.

Description

[0001] This application is a divisional application of an invention patent application with the filing date of December 4, 1998, the application number of 98811857.2, and the title of the invention entitled "Equipment and method for performing handover in a mobile communication system". technical field [0002] The present invention relates to a mobile communication system, in particular to a device and method for performing handoff in the mobile communication system. Background technique [0003] In mobile communication systems, there are several handoff methods for maintaining a call when a terminal (or mobile station) moves from a current cell (or base station) area to an adjacent cell area. One is a soft handoff method, and the other is a hard handoff method. In the soft handoff method, a terminal communicates by using the assigned channel from the handoff target base station to which the terminal is handing off and the assigned channel from the current base station curr...
