Combined long and short distance wireless communication system and its method
First Claim
1. A combined long and short distance wireless communication system comprising:
- a dual distance terminal for providing subscribers with long and short distance communication services;
at least one remote distance base station for providing remote distance wireless access for said dual distance terminal;
at least one short distance access point (AP) for providing short distance wireless access for said dual distance terminal; and
a dual distance network server for connecting said at least one remote distance base station and said at least one short distance AP to execute network switching for said dual distance terminal and enabling said dual distance terminal to access the network to which it is switched, storing data that may be missed during switching and sending the stored data to said dual distance terminal after said terminal switching is completed.

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.

8. A wireless communication method using combined long and short distance wireless communication systems, comprising steps:
-
detecting a dual distance terminal to determine whether it is located in a service area covered by a short distance access point;
entering a short distance communication network through the short distance access point in the case where the dual distance terminal is located within the service area covered by the short distance access point, and informing a dual distance home server of the position of the dual distance terminal;
searching for a base station for a long distance communication service if the dual distance terminal is not located in the area covered by any one of the short distance access points, entering a long distance communication network through a base station for a long distance communication service, and informing the dual distance home server of the position of the dual distance terminal;
switching between a long distance communication network and a short distance communication network when the dual distance terminal enters the short distance network service area from the long distance network service area, or enters the long distance network service area from the short distance network service area, and storing data that may be missed during switching, and sending the stored data to a dual distance terminal via said data service function entity after said network switching is completed. - View Dependent Claims (9, 10, 11, 12, 13, 15, 16, 18, 19, 21, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
