First Claim
1. 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.

Abstract
A network service connecting system is provided which is capable of eliminating waste in establishing association between a wireless user terminal and an access point. A service ID (Identification) producing section produces a service ID containing a service application ID and a service vendor ID. A Probe request transmitting section transmits the service ID to the access point. A data storing section holds data on associated relations among service, a service vendor, and a V-LAN (Virtual Local Area Network) switch. When a Probe request receiving section receives a service ID, an SSID (Service Set Identification) judging section, by referring to the above data on the associated relation, judges whether an ID of the service vendor is contained in the service ID. If it is contained, a Probe response transmitting section transmits an SSID to the wireless user terminal.

9. A network service connecting computer program making a wireless user terminal enabled by an access point to be connected to a service vendor on a network via a wireless LAN perform a first step of producing a service ID 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 and perform a second step of searching, by using said service ID, for an access point existing in an area where said wireless user terminal is communicable,
wherein said first step further comprises a step in which said wireless user terminal adds detecting option information indicating whether or not said service application ID contained in said service ID is indispensable to said application to said service ID for every said service application ID.

12. A network service connecting computer program making an access point which enables a wireless user terminal to be connected to a service vendor on a network via a wireless LAN perform a first step of judging, when receiving a service ID transmitted from said wireless user terminal, by referring to a table which stores 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-ID being an ID of a V-LAN switch serving as a mediator for connection between said service vendor and said access point, whether or not said service vendor ID associated with said service application ID contained in said service ID is contained in said service ID, performs a second step of selecting, only when judging said service vendor ID corresponding to said service application ID to be contained in the service ID in said first step, a VLAN-ID corresponding to said service vendor ID, and perform a third step of transmitting, only when judging said service vendor ID corresponding to said service application ID to be contained in the service ID in said first step, an SSID (Service Set Identification) set at said access point to said wireless user terminal,
wherein, in said first step, by referring to said table, judgment is made as to whether or not said service vendor ID is contained in said service ID, said service vendor ID corresponding to said service application ID to which a detecting option indicating that said service application ID is indispensable to said application has been added is contained in said service ID.

16. A wireless user terminal enabled by an access point to be connected to a service vendor on a network via a wireless LAN comprising:
-
a first unit to produce a service ID 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; and a second unit to search, by using said service ID, for an access point existing in an area where said wireless user terminal is communicable, wherein said first unit further comprises a unit to add detecting option information indicating whether or not said service application ID contained in said service ID is indispensable to said application to said service ID for every said service application ID. - View Dependent Claims (17, 18)
