    Abstract: 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.

    Abstract: A method, a device, and a non-transitory storage medium provide to store packet data network (PDN) connection data pertaining to a user equipment connected to a network; store locale-to-packet data network gateway (PGW) data, wherein the locale-to-PGW data includes mappings between locales and PGWs to be used when the user equipment is located in the locales; receive a locale update pertaining to the user equipment; query the locale-to-PGW data in response to the locale update; determine, based on a result of the query, whether the user equipment is to be re-anchored to a different PGW than a PGW to which the user equipment is currently anchored; invoke a re-anchoring procedure, in response to a determination that the user equipment is to be re-anchored to the different PGW; and omit to invoke the re-anchoring procedure, in response to a determination that the user equipment is not to be re-anchored.
