摘要： Improved techniques for reducing delays faced by users of mobile devices due to unavailability of wireless networks are disclosed. The techniques facilitate the reduction of delays faced by users of mobile devices during unavailability of wireless networks. A first technique allows mobile devices to communicate with remote servers using asynchronous communications, namely asynchronous requests. Such asynchronous communications allow the processing at a mobile device to continue while the asynchronous request is processed in the background. A second technique pertains to the use of content channels with mobile devices. The content channels are stored and retained in cache memory so that their resources are guaranteed to be locally available, regardless of availability of wireless networks. A third technique pertains to improved list processing within mobile devices such that lists can be manipulated without server interaction. These various techniques can be used separately or in combination.
