Sensor network management system

A computer system including wireless terminals, wireless base stations connected to said wireless terminals through a first wireless communication network, and a name server computer and a task server computer connected to said wireless base stations through a second communication network, wherein said name server computer comprises:

• a wireless terminal combination rule for combining a plurality of wireless terminals so that they can be looked up as a logically single wireless terminal, and wireless terminal combination rule management means for managing said wireless terminal combination rule;
• a wireless base station combination rule for combining a plurality of wireless base stations so that they can be looked up as a logically single wireless base station, and wireless base station combination rule management means for managing said wireless base station combination rule;
• a wireless terminal and wireless base station combination rule for combining a plurality of wireless terminals and base stations so that they can be looked up as a correspondence relation of a logically single wireless terminal and a logically single wireless base station, and wireless terminal and wireless base station combination rule management means for managing said wireless terminal and wireless base station combination rule;
• and
• wireless terminal and wireless base station combination control means for interpreting a reference request to said logically single wireless terminal by using said wireless terminal combination rule, said wireless base station combination rule and said wireless terminal and wireless base station combination rule, deciding the combination of a plurality of said wireless terminals and said wireless base stations, sending said wireless terminal reference request for the combination so decided, receiving the result of said reference request sent, and generating the result of said reference request for said logically single wireless terminal by combining said result information received in accordance with said interpretation.

A communication method of a computer system including a plurality of terminals, a plurality of base stations communicating with said terminals through a first network and a server communicating with said base stations through a second network, wherein:

• said terminal has a memory for storing a terminal identifier for identifying said terminal itself;
• said base station has a memory for storing a terminal identifier of said terminal with which said base station communicates and a relay identifier in association with each other;
• said server has a memory for storing, in association with one another, an identifier of said base station, and said terminal identifier and said relay identifier stored in said base station in association with each other;
• when communication is made with a specific terminal from any part inside said second network, said memory of said server is retrieved and said relay identifier is sent to said base station on the basis of said relay identifier and said identifier of said base station associated with a terminal identifier representing said specific terminal;
• and
• said base station retrieves said memory on the basis of said relay identifier received and gains access to said terminal having said terminal identifier associated with said relay identifier.
