LOCAL SERVICE HANDOVER
Document Type and Number:
WIPO Patent Application WO2003039009
Kind Code:
A3
Abstract:
The technical features mentioned in the abstract do not include a reference sign between parentheses (PCT Rule 8. 1 (d)). When a mobile wireless device (100) is within the area of a short-range wireless access point (140A), it sends a request for service to be obtained from a network server (180). The access point receives a response from the server (180), including a global/local parameter to notify the mobile device (100) whether the requested service is available outside the area of the access point (140A). Regions outside the area of the access point are covered by cellular telephone base station (148). If the mobile device (100) detects that it has left the area of the access point (140A) while in contact with the server (180), it will determine whether the parameter indicates that the service is global. If it is global, then the mobile device (100) makes a cellular connection to the server (180).
