ABSTRACT:
Techniques for controlling and managing network access are used to enable a wireless communication device to selectively communicate with several wireless networks. A portable communication device constructed according to the invention can communicate with different networks as the device is moved through the areas of coverage supported by the different networks. As a result, the device can take advantage of services provided by a particular network when the device is within the area of coverage provided by that network. Thus, the device can selectively switch to networks that provide, for example, high speed Internet access, different quality of service, low cost service and/or different services (e.g., voice, data, multimedia, etc.). A multi-mode controller in the device may be used to alternately poll different networks to determine whether the device is within the area of coverage of a network and to selectively establish communications with those networks.
