AI Technical Summary

Problems solved by technology

That is, the mobile communication system has the advantages of wide service area and high-speed mobility, but it is disadvantageous when downloading large-capacity data such as animation and music due to the high initial price and charging according to usage.
[0009] On the other hand, the wireless LAN system has the advantages of realizing high-speed data communication and providing services at a low price or at a fixed price due to the simple system construction; However, it consumes a large amount of frequency resources (bandwidth) and becomes a local area (for example, a hot spot area of ​​hundreds of meters) service area.

Abstract

Have: the 1st mobile communication terminal (100) (for example: portable information terminal), it has the 1st wireless LAN interface (30,31) that can provide one or more wireless LAN client functions; The 2nd mobile communication terminal ( 200) (for example: mobile phone), which has a second wireless LAN interface (18, 19) that can provide wireless LAN access point or wireless LAN client function. When the user is located in the wireless LAN hotspot area (32), the user performs wireless LAN access using the first mobile communication terminal (100). On the other hand, when the user is located at the border of the wireless LAN hotspot area (32), the wireless access is automatically maintained via the second mobile communication terminal (200). Accordingly, it is possible to enjoy the respective advantages of the mobile communication system and the wireless LAN system at the same time.

Description

technical field [0001] The present invention relates to a wireless communication system, which comprises: a first mobile communication terminal (for example: a portable information terminal), which has a wireless LAN interface capable of providing one or more wireless LAN client functions; a second mobile communication terminal (for example, : mobile phone) having a wireless LAN interface that can provide a wireless LAN access point or wireless LAN client function. Background technique [0002] At present, there are wide-area coverage data communication services with a speed of hundreds of Kbps, which use W-CDMA (Wideband Code Division Multiple Access: Wideband Code Division Multiple Access), GSM (Global System for Mobile Communications: Global System for Mobile Communications), GPRS (General Packet Radio Service: General Packet Radio Service), CDMA2000 and other mobile communication systems. [0003] In addition, there is currently a high-speed data communication service w...
