Claim Text:
1. A communication system for establishing a connection between a base station and a plurality of virtual LANs (VLANs) provisioned in an Ethernet network, comprising: a plurality of gateways each belonging to a different one of the plurality of VLANs and connecting the one of the plurality of VLANs with another network, and configured to include service-ID associating information in which a service-ID identifying each of one or more services to be provided is stored in association with a VLAN identifier identifying a VLAN to be used for providing the each of the one or more services; a base station configured to connect with the Ethernet network; and a switch configured to: the switch, upon receiving from the base station a first VLAN frame including a predetermined VLAN-ID that is to be set to a VLAN tag of a VLAN frame and is not assigned to any one of the plurality of VLANs, broadcasts the first VLAN frame including the predetermined VLAN-ID to all the plurality of gateways via the plurality of VLANs before establishing connections with the plurality of VLANs; each gateway, upon receiving the first VLAN frame including the predetermined VLAN-ID from the switch through a VLAN to which the each gateway belongs, transmits the service-ID associating information stored in the each gateway to the switch, the switch, upon receiving the service-ID associating information from each gateway, transfers the received service-ID associating information to the base station, the base station stores the received service-ID associating information in a memory thereof, and the base station, for a given service-ID identifying a service to be provided, selects, from among the plurality of VLANs, at least one VLAN that is associated with the given service-ID by the service-ID associating information stored in the memory, and establishes a connection with the selected at least one VLAN so as to provide a service identified by the given service-ID using the selected at least one VLAN.
