Mobile communication system and base station device thereof

Abstract

The invention provides a mobile communication system and a base station device thereof for improving the performance of a mobile communication terminal to move in a high speed. In the base station device, a communication control part respectively allocates random base station identifiers to a plurality of wireless connection parts which form honeycombs capable of wireless connecting, transmits communication data from a gateway device, and allocates random wireless channel to the wireless connection parts allocated with the base station identifiers according to each wireless connection with the mobile communication terminal. Thus, an independent channel can set a common channel corresponding to the base station identifiers. Viewing from the mobile communication terminal, the communication with the wireless connection part dispersed and configured in a geographic area is like the communication with the base station. Thus, various processes about handover are omitted and the wireless connection parts connecting with the destination are switched, thereby reducing the time for processing the handover, and capable of continuously communicating under the condition that the mobile communication terminal moves in the high speed.

Description

technical field [0001] The present invention relates to a mobile communication system and a base station device in which a mobile communication terminal PS is wirelessly accommodated in a base station device, and a communication environment is formed between a communication network and the mobile communication terminal via a gateway device. Background technique [0002] The systems for forming areas of the mobile communication system are roughly classified into a macro cell system and a micro cell system. A typical target of the former is a so-called portable telephone system, and the radius of each wireless area reaches several kilometers. On the other hand, for example, PHS (Personal Handy-Phone System: Personal Handy-Phone System) adopts the latter method, and the area radius is at most about several hundred meters, which is very small. [0003] In the microcell system, base stations are frequently added or removed according to changes in regional communication needs. F...

Problems solved by technology

In this document, the size of the paging area is variable to cope with repeated handovers on the border of the paging area. However, since handovers also occur within the paging area, it is not fundamental to improve the performance of high-speed mobility. response

In addition, a scheme has been proposed in which the mobile communication terminal can predict the base station to be connected to next, but it is difficult to deal with the case where the terminal moves unexpectedly
