Claim:
1. A method for anticipating the loss of connectivity between a mobile device and a wireless short-range access point among a plurality of such wireless access points, the method comprising: collecting identifiers of access points to which the mobile device was successively associated without loss of connectivity and the duration of each of these associations so that reproducing a plurality of paths corresponding to the mobile device movements within the coverage areas of the access points to which the said mobile device was successively associated without loss of connectivity, each path comprising a root access point at which a connectivity is originated and a dead-end access point at which the connectivity is lost; detecting a current access point to which the mobile device is currently associated; identifying the paths comprising the current access point; computing risks of losing the connectivity when following each of the identified paths from the current access point to the root access point or to the dead-end access point of each of the identified paths, the risk of losing connectivity when following a path from a first access point to a second access point being the inverse of the sum of the collected durations of association corresponding to the access points comprised in the path from the first access point to the second access point; and triggering a handover based on a computed risk of the computed risks.
