Internet based remote diagnostic system
First Claim
1. A remote diagnostic communication system comprising:
- a centrally located diagnostic center;
a point-of-presence (POP) server located on a network coupled to said centrally located diagnostic center;
at least one remote site for collecting diagnostic data and for initiating a local connection to said POP server to transfer said diagnostic data to said POP server so that said diagnostic data can then be retrieved from said POP server by said centrally located diagnostic center; and
a paging channel between said centrally located diagnostic center and said at least one remote site for prompting said at least one remote site to initiate said local connection to said POP server.

Abstract
Public or private remote access infrastructures in a communication system are used to facilitate communications between a remote site and a centrally located diagnostic center using only local telephone calls. The diagnostic center as well as one or more remote sites at which monitored equipment is located are coupled to a wide area network (WAN). When data are to be transferred from a remote site to the central diagnostic center, the remote site initiates a local telephone call to a point-of-presence (POP) server on the WAN backbone. This could be an Internet Service Provider (ISP) if the Internet is used, or an intranet if a private network is used. Data are then transferred to the POP server. To complete the transfer, the diagnostic center retrieves the data from the POP server using the public or private wide-area network (the Internet or intranet). The data transfer can be performed either on a scheduled basis, or when an alarm condition is detected at the remote site. The central diagnostic center can use a wireless paging service to prompt the remote site to couple to the POP server.

6. A method for communicating diagnostic data between a remote site and a central diagnostic center while avoiding use of long distance telephone services, the method comprising the steps of:
-
coupling a centrally located diagnostic center to a network;
placing at least one remote diagnostic monitoring station at a remote site for collecting diagnostic data at said remote site;
initiating a local coupling between said at least one remote diagnostic monitoring station and a point-of-presence (POP) server on said network;
transferring said diagnostic data from said at least one remote diagnostic monitoring station to said POP server for retrieval therefrom by said centrally located diagnostic center; and
initiating a page from said centrally located diagnostic center to said at least one remote diagnostic monitoring station for prompting said at least one remote diagnostic monitoring station to couple to said POP server wherein the step of initiating a local coupling is performed by said at least one remote diagnostic monitoring station.
