Self-recovery method and device after disconnection of base station

A self-recovery method after disconnection of a base station, applied to a network management system side, comprising:

• the network management system receiving a request for acquiring an Internet Protocol, IP, address sent by a base station through an underlying communication protocol, wherein the request carries a unique identification of the base station;
• after receiving the request for acquiring the IP address, the network management system searching for the IP address corresponding to the unique identification in base station information which is saved in advance, and returning the searched IP address to the base station;
• the network management system establishing an IP link with the base station according to the IP address;
• and
• the network management system sending base station software and configuration data for information loading to the base station according to the request of the base station.

A self-recovery device after disconnection of a base station, arranged in a base station, comprising a link interruption detection module and a self-recovery module, wherein:

• the link interruption detection module is configured to, when the base station cannot connect with a network management system through a link, detect a cumulative time length for link interruption;
• and
• the self-recovery module is configured to, when the cumulative time length for link interruption detected by the link interruption detection module exceeds a designated time length, send a request for acquiring an Internet Protocol, IP, address to the network management system through an underlying communication protocol, wherein the request carries a unique identification of the base station;
• establish an IP link with the network management system according to the IP address returned by the network management system;
• and load base station software and configuration data according to information acquired from the network management system.

A self-recovery device after disconnection of a base station, arranged at a network management system side, comprising a self-recovery service module and a base station information table saving module, wherein:

• the self-recovery service module is configured to, when receiving a request for acquiring an Internet Protocol, IP, address sent by a base station through an underlying communication protocol, search for the IP address, corresponding to a unique identification of the base station in the request, in base station information which is saved in advance, and return the searched IP address to the base station;
• establish an IP link with the base station according to the IP address;
• and send base station software and configuration data for information loading to the base station according to the request of the base station;
• and
• the base station information table saving module is configured to save the IP address of the base station, the base station software and configuration data for information loading and a patch pack.
