Problems solved by technology

Inquiry, paging, and operational exchange processes can be factors that delay data communication time and can degrade system performance, which are directly related to data loss
[0021] Moreover, referring to the hard handover throughput (throughput) shown in FIG. 6, it can be seen that when the hard handover method is adopted, even when the handover is completed to initiate reconnection, due to the transmission control protocol (TCP) exponential back -off) still causes greatly reduced throughput

Embodiment Construction

[0038] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0039] FIG. 7 is a schematic diagram briefly showing a wireless communication system according to an embodiment of the present invention.

[0040] Referring to FIG. 7 , the wireless communication system includes: a first communication device 61 , a wireless communication device 63 and a second communication device 65 . The first communication device 61 , the wireless communication device 63 and the second communication device 65 are each equipped with a Bluetooth technology system. Also, the first communication device 61 and the second communication device 65 may be connected through a separate wired network. Here, when the devices 61 and 65 are connected to each other not through a separate wired network but through a wireless network, the first communication device 61 and the second communication device 65 are preferably separated from each other within a com...

Abstract

Disclosed is a wireless communication system capable of minimizing the hand-off throughput for wireless communication systems. The wireless communication system according to the present invention includes a first communication device for carrying out an inquiry and paging with respect to a wireless communication device located within a communication allowance range, and starting a connection with the wireless communication device; and a second communication device for receiving and transmitting data with the wireless communication device when the wireless communication device connected with the first communication device is cut off by a hard hand-off.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2002-68344 filed with the Korean Intellectual Property Office on November 6, 2002, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a system and method for increasing the communication speed of a wireless communication system, in particular to a system and method for supporting handover due to movement of mobile equipment in a time division duplex (TDD) wireless communication system. Background of the invention [0003] Bluetooth (Bluetooth) is synonymous with wireless data communication technology covering telecommunications, networking, computing and consumer fields. Bluetooth technology uses a single wireless connection within a local area, replacing the multiple cable connections required between devices. For example, if Bluetooth wireless technology is used in...
