Long and short distance combined wireless communication system and method thereof

Abstract

This invention provides a combined long and short distance wireless communication system and method thereof. A dual distance terminal provides subscribers with the long and short distance wireless communication service and guarantees that the service isn't interrupted when switching between different networks occurs. A remote distance base station provides the dual distance terminal with remote distance wireless access. A short distance AP provides the dual distance terminal with short distance wireless access. A dual distance network server connects the remote distance base station and the short distance AP to switch between networks and make the dual distance terminal access the network to which is switched. The present invention enables the dual distance terminal within the coverage of the long and short distance wireless system to communicate with the long distance networks and automatically switch to short distance wireless local area networks (WLAN) when the dual distance terminal enters the short distance WLAN so that seamless switch is achieved. The subscribers having different priority levels access different short distance WLANs with different levels after authority identification.

Description

technical field [0001] The invention relates to a wireless communication system and its realization, in particular to a wireless communication system which combines long-distance and short-distance wireless communication technologies and realizes seamless switching links, and belongs to the field of communication technology. Background technique [0002] The current communication network mechanism, GSM / GPRS and future 3G are long-distance communication. The main characteristics of long-distance communication are: large coverage area, low laying costs, high operating costs, low transmission rate, etc. It manifests itself in the concept of "ocean". At present, such as 802.11 and BT, etc., are short-distance communication methods. It is characterized by limited coverage, high laying costs, low operating costs, and high transmission rates in office areas and specific commercial areas. It is manifested as the concept of "islands", which are isolated one by one and obviously ha...
