Abstract

A communication device having a communication module as data circuit-terminating equipment connecting to a wireless packet communication network, and a controller interposed between the communication module and a data terminal equipment. The controller controls communication performed by the data terminal equipment using the communication module. The controller extracts, from a communication message sent from the data terminal equipment to a first management server, identification information of the data terminal equipment, stores the extracted identification information in a storage, and transmits the extracted identification information to a second management server by using the communication module when communication is not performed between the data terminal equipment and the first management server.

Claims

1. A communication device comprising a communication module as data circuit-terminating equipment connecting to a wireless packet communication network, and controller interposed between the communication module and data terminal equipment, the controller controlling communication performed by the data terminal equipment using the communication module, wherein:

the controller extracts, from a communication message sent from the data terminal equipment to a first management server, identification information of the data terminal equipment, stores the extracted identification information into a storage, and transmits the extracted identification information to a second management server by using the communication module when communication is not performed between the data terminal equipment and the first management server.

2. The communication device according to claim 1, wherein the controller obtains position information about an installation place by using a position information service offered in the wireless packet communication network, stores the position information into the storage together with the identification information, and transmits the position information to the second management server together with the identification information.

3. The communication device according to claim 1, further comprising position information obtaining means for obtaining position information about an installation place,

wherein the controller obtains position information from the position information obtaining means, stores the position information into the storage together with the identification information, and transmits the position information to the second management server together with the identification information.

4. The communication device according to claim 1 wherein the identification information comprises information for identification of the data terminal equipment in communication between the data terminal equipment and the first management server, and the communication corresponds to an application layer of an OSI reference model.

5. A communication management system comprising:

a communication device including a communication module as data circuit-terminating equipment connecting to a wireless packet communication network, and controller for controlling communication using the communication module;

data terminal equipment which performs communication with the communication device;

a first management server which performs centralized control of the data terminal equipment; and

a second management server which performs centralized control of the communication device,

wherein the controller extracts, from a communication message sent from the data terminal equipment to the first management server, identification information of the data terminal equipment, stores the extracted identification information into a storage, and transmits the extracted identification information to the second management server by using a communication module when communication is not performed between the data terminal equipment and the first management server, and

wherein the second management server stores, into a storage, identification information of the communication device and the identification information of the data terminal equipment received from the communication device relationally.
