During the period when a mobile wireless device is within the coverage area of a short range wireless access point, it sends a request for service to be obtained over the Internet from a network server. The short range wireless access point receives a response message over the Internet from the server, including a global/local parameter to notify the mobile wireless device whether the requested service is available outside the coverage area of the short range wireless access point. The access point forwards the response message to the mobile wireless device, which uses the information in the message to contact the server over the Internet to download web pages or to conduct other server operations. Regions outside the coverage area of the short range wireless access point are covered by regional cellular telephone access points, such as cellular telephone base stations. If the mobile wireless device detects that it has left the coverage area of the short range wireless access point while in contact with the server, it will determine whether the global/local parameter indicates that the service is global. If the parameter is global, then the mobile wireless device accesses a stored handover address, which is typically the telephone number of a protocol gateway connected between the cellular telephone network and the Internet. A cellular telephone connection is made by the mobile wireless device with the regional cellular telephone access point and a cellular telephone call is placed to the protocol gateway. When the call is completed over the telephone network, the mobile wireless device sends a message to the protocol gateway, which it forwards to the server. Depending on the request, the server responds by resuming the operations it had previously been conducting in its prior contact with the mobile wireless device.
