Network management system and network management information collecting method
First Claim
1. A method for seamlessly collecting information from a mobile node in wireless network environment, in which a Manager gets the information related to network devices by polling Agents comprising:
- seamlessly collecting the information, which the Agent has stored during the period of the disconnection between the Manager and the Agent, by sending the Agent a request for a label-specified data pertaining to the period of the disconnection when detecting recovery of the connectivity after the connectivity between the Manager and the Agent is lost, and judging the reboot status of the Agent when detecting discontinuous data in the information collected from the Agent; and
seamlessly collecting the information at a minimum time lag, when a time lag between the Manager and the Agent occurs, by continuing to resend requests for the label-specified data at pre-configured intervals Tn upon the Manager receiving a response of “
no data”

Abstract
This invention aims to provide a technique that, in wireless network environments, enables the Manager to collect network management information (MIB data in the case of SNMP based network management), which the Agent has stored during periods of disconnection, after connectivity to the mobile nodes has recovered. In a wireless network environment, the Agent (201) has a unit for storing the management information related to network devices with appropriate label information, while the Manager (101) has a unit for sending the Agent a request for a label-specified data, and getting the data which the Agent has stored in Management Information Store 207. The above unit enables the Manager (101) to seamlessly collect the information pertaining to the period of disconnection, which the Agent (201) has stored in Management Information Store 207, after detecting recovery of the connectivity.

4. A Network Management System, comprising:
-
microprocessors programmed to perform as; a Manager which gets the information related to network devices by polling Agents in wireless network environment by sending the Agent a request for a label-specified data at pre-configured Polling-intervals P and receiving the data pertaining the label-specified data from the Agent; and an Agent which samples the relevant probes for management information at pre-configured time intervals P′
, appends appropriate label information to the sampled management information, and stores the labeled sampled information in a Management Information Store,wherein the Manager comprises seamlessly collecting the information, which the Agent has stored during the period of the disconnection between the Manager and the Agent, by sending the Agent a request for a label-specified data pertaining to the period of the disconnection when detecting recovery of the connectivity after the connectivity between the Manager and the Agent is lost, and judging the reboot status of the Agent when detecting discontinuous data in the information collected from the Agent; and seamlessly collecting the information at a minimum time lag, when a time lag between the Manager and the Agent occurs, by continuing to resend requests for the label-specified data at pre-configured intervals Tn upon the Manager receiving a response of “

7. A SNMP Network Management System, comprising:
-
microprocessors programmed to perform as; a SNMP Manager which gets the information related to network devices by polling SNMP Agents in wireless network environment by sending the SNMP Agent a request for a label-specified data at pre-configured Polling-intervals P and receiving the data pertaining the label-specified data from the SNMP Agent; and a SNMP Agent which samples the relevant probes for management information at pre-configured time intervals P′
, appends appropriate label information to the sampled management information, and stores the labeled sampled information in a Management Information Store,wherein the SNMP Manager comprises seamlessly collecting the information, which the SNMP Agent has stored during the period of the disconnection between the SNMP Manager and the SNMP Agent, by sending the SNMP Agent a request for a label-specified data pertaining to the period of the disconnection when detecting recovery of the connectivity after the connectivity between the SNMP Manager and the SNMP Agent is lost, and judging the reboot status of the SNMP Agent when detecting discontinuous data in the information collected from the SNMP Agent; and seamlessly collecting the information at a minimum time lag, when a time lag between the SNMP Manager and the SNMP Agent occurs, by continuing to resend requests for the label-specified data at pre-configured intervals Tn upon the SNMP Manager receiving a response of “
no data”
