Abstract:
1. A reachability realization server that realizes reachability from a service-providing server held by a service-providing first user to a second user, comprising: a real-address-information receiving section that receives real-address information, which is capable of contacting there through to the second user, from a second terminal used by the second user; a service-provider storage section that stores therein server-identification information, which is capable of identifying at least one service-providing server, in association with service-identification information that is capable of identifying a plurality of services; a post-conversion-address-information generation section that generates post-conversion-address information, which the first user cannot specify, and which corresponds to said real-address information received by said real-address-information receiving section and said service-identification information; an access-request transfer section that transfers to said second user terminal an access request to said first user terminal based on said real address information extracted by said real-address-information extraction section; an address-information storage section that stores, in association with a specific state in a business flow, said post-conversion-address information generated by said post-conversion-address information in association with said real-address information of the second user; a real-address-information extraction section that extracts, upon receiving an access request including said post-address information from a first user terminal used by the first user, said real-address information corresponding to said post-conversion-address information included in said received access request from said address-information storage section; an access-request transfer section that transfers to said second user terminal said access request from said first user terminal based on said real-address information extracted by said real-address-information extraction section an update-process-information storage section that stores, in association with a specific state in a business flow, update-process information representing a processing of updating the information stored in said address-information storage section; an update-process-information extraction section that extracts, upon receiving event information including information representing said post-conversion-address information and a present state from said first user terminal, said update-process information from said update-process-information storage section based on the information representing said present state included in said received event information; an address-information update section that updates the information stored in said address-information storage section based on said update-process information extracted by said update-process-information extraction section and said post-conversion-address information included in said received event information; an access acceptance/rejection judgment section that judges, based on the information stored in said real-address-information storage section, access acceptance or rejection with respect to said access request from said first user terminal to said second user terminal; and a retrieval section that retrieves said real-address information of the second user based on said post-conversion address information received from said service-providing server.
