ABSTRACT:
A method, system, and medium are provided for increasing the robustness of communications sessions between mobile devices and communications networks through handoff diversity. Separating the handoff times through handoff diversity provides for continuous transmission of data and decreases the likelihood of dropped calls and lost data. In a communications session capable of communicating data through multiple channels, handoff diversity is implemented by ensuring that at least one communication channel's handoff is complete and transferring data prior to initiating a handoff within another channel. In one illustrative embodiment, the present invention configures the physical propagation environment of the channels to create diversity in channel-handoff occurrences. In another illustrative embodiment, the communications network or mobile device is configured to force channel-handoff diversity by delaying a handoff for one or more communication channels.
