Patent ID: 7200362

Claim:
A network service connecting method by which an access point enables a wireless user terminal to be connected to a service vendor on a network via a wireless LAN (Local Area Network), said method comprising: a first step in which said wireless user terminal produces a service ID (Identification) containing a service application ID being an ID of service required for execution of a specified application selected by said wireless user terminal and a service vendor ID being an ID of said service vendor holding authentication information which is required for said wireless user terminal to be connected to said service vendor; a second step in which said wireless user terminal, by using said service ID, searches for an access point existing in an area where said wireless user terminal is communicable; a third step in which an access point having received said service ID, by referring to a table storing data on associated relations among a service application ID, a service vendor ID of a service vendor providing service identified by said service application ID, and a VLAN (Virtual Local Area Network)-ID being an ID of a V-LAN switch serving as a mediator for connection between said service vendor and said access point, judges whether or not a service vendor ID corresponding to a service application ID included in said service ID is contained in said service ID; a fourth step in which said access point, only when judging said service vendor ID corresponding to said service application ID to be contained in the service ID in said third step, selects a VLAN-ID corresponding to said service vendor ID; and a fifth step in which said access point, only when judging said service vendor ID corresponding to said service application ID to be contained in the service ID in said third step, transmits an SSID (Service Set Identification) set at said access point to said wireless user terminal.
