Handover proactive association clearing support method and system

摘要

A handover proactive association clearing support method and system supports minimizing handover times for at least one netsurfing end system, and optimizing a given market satisfaction function (MSF0) potentially depending on Internet-applications for whichever underlying HO technique, by potentially establishing pre-HO for free x/yz-, netsurfing x/yz-, and/or Sxyzj-association, called “clearing” them. An HO of an Ayz is optimal if its HO-time is “basically zero” and it complies with MSF0. The technical innovation of the method and system comprises for an Ayz determining any time its optimal HOs. This permanent predetermination of optimal HOs implies assessing permanently all parameters. Thus, when an Ayz must perform an HO, these pre-HO operations of the method/system would have already identified at least one optimal HO for it to a sharedIADx and/or an Sxyzj available to it and established the resp. x/yz-, netsurfing x/yz-, and Sxyzj-associations.

1. A method for proactively establishing associations of a netsurfing end-system having a home Integrated Access Device (IAD) to at least one shared IAD and/or at least one application service, prior to a handover of said netsurfing end-system between IADs or between application services, comprising:
checking for a signal indicating that the netsurfing system may perform a handover within a given time t1>0 to either a shared IAD and/or to a network application service different from an IAD or application currently being used by the netsurfing end-system; in response to receiving said signal, and prior to any handover operation, establishing an association of at least one shared IAD and/or network application service with said netsurfing end-system via said home IAD; whereby a time required to complete handovers of said netsurfing end-system between shared IADs or network application services is reduced relative to a time required to complete such handovers without such pre-handover associations.
