Context information collection management system

摘要

A context information collection and distribution system registers read identification information in a computer device that manages and controls an RFID tag reading device and is located in a lowest hierarchy in wide area network topology. The computer device located in the lowest hierarchy in the wide area network topology notifies a computer device located in a higher management domain hierarchy that the computer device located in the lowest hierarchy manages read identification information of a target. Further, the computer device located in the management domain hierarchy notifies a computer device located in much higher ID system hierarchy that the computer device located in the hierarchy just under the management domain hierarchy manages the read identification information of the target.

1. A context information collection management system for managing a target ID, the target ID including a first part and a second part, the first part identifying a type of a target and a domain to which the target belongs, a second part uniquely identifying the target, the context information collection management system comprising:
a first computer device that is disposed in a first hierarchy; second computer devices that are disposed in a second hierarchy just under the first hierarchy; third computer devices that are disposed in a third hierarchy just under the second hierarchy; and fourth computer devices that are disposed in a fourth hierarchy just under the third hierarchy, wherein each of the third computer devices
comprises a first table having a correspondence relationship between the first part, the second part and an ID of each of the fourth computer devices,obtains the target ID,when a combination of the first part and the second part included in the obtained target ID exists in the first table, transmits the obtained target ID to a specific fourth computer device having an ID corresponding to the existed combination among the fourth computer devices, andwhen the combination of the first part and the second part included in the obtained target ID does not exist in the first table, transmits the obtained target ID to any one of the second computer devices, and each of the second computer devices
comprises a second table having a correspondence relationship between the first part and an ID of each of the third computer devices,receives the target ID transmitted from any one of the third computer devices,when the first part included in the received target ID exists in the second table, transmits the received target ID to a specific third computer device having an ID corresponding to the existed first part among the third computer devices, andwhen the first part included in the received target ID does not exist in the second table, transmits the received target ID to the first computer device.
