Network, private branch exchange, wireless LAN terminal, and multiprotocol communication terminal control method therefor
First Claim
1. A network comprising:
- at least one session initiation protocol (SIP) terminal for performing communication based on a session initiation protocol that implements connection-oriented communication in which communication is performed upon confirmation of a connection with another terminal in an internet protocol (IP) network;
a private branch exchange for performing call connection processing between terminals;
a database; and
a wireless local area network includingan access point that is connected to the private branch exchange through a transmission path, andat least one wireless local-area-network terminal that belongs to the access point and notifies of unique identifier information of the access point;
wherein the private branch exchange comprises at least one session-initiation-protocol protocol control module, obtained by modularizing processing of the session initiation protocol through use of a scheme of a back-to-back user agent (B2BUA) that acts as a proxy user agent and incorporated as one component; and
a location-information management module, incorporated as one component, for managing the unique identifier information of which the wireless local-area-network terminal notifies,wherein the unique identifier information of the access point comprises a basic service set identifier (BSSID), andwherein the location-information management module collects the unique identifier information that comprises the BSSID, and records the unique identifier information in the database.

Abstract
A standard-SIP (session initiation protocol) protocol control module and an expanded sip protocol control module are provided so as to correspond to respective Sip protocol corresponding terminals, such as wireless LAN terminals compliant with the SIP. A signal (a request) from each Sip protocol corresponding terminal is converted into a signal according to a protocol of an IP-PBX and is sent to a PBX basic-connection-processing providing module. A signal (a response for the request or a request to the Sip protocol corresponding terminal) from the PBX basic-connection-processing providing module is converted into an Sip protocol signal and is sent to the Sip protocol corresponding terminal. A location-information management module collects a basic service set identifier (BSSID) from each wireless LAN network and stores the BSSID information into a database.
