Portable internet radio access station including multiple management processors and method of controlling the multiple management processors

A portable internet RAS including a plurality of management processors, comprising:

• first and second management processors operating coupled with each other;
• and
• an operation state determining unit determining an operation state of the first and second management processors based on an obstruction in the first and second management processors,
• wherein the plurality of management processors includes the first and second management processors,
• wherein the first management processor comprising:
• a first call processing database storing a call processing information of the portable internet RAS;
• and
• a first database synchronizing unit synchronizing the first call processing database with a second call processing database based on the operation state, and
• wherein the second management processor comprising:
• the second call processing database storing the call processing information of the portable internet RAS;
• and
• a second database synchronizing unit synchronizing the second call processing database with the first call processing database based on the operation state.

A portable internet RAS comprising a plurality of management processors,

• wherein the plurality of management processors includes the first and second management processors,
• wherein the first management processor is initialized in an active state and the second management processor is initialized an auxiliary active state,
• wherein when an obstruction is sensed in the first management processor, the first management processor is transited from the active state to an inactive state and the second management processor is transited from the auxiliary active state to a single active state, and
• wherein when the obstruction is sensed in the second management processor, the first management processor is transited from the active state to the single active state and the second management processor is transited from the auxiliary active state to the inactive state.

A method of controlling first and second management processors of a portable internet RAS, comprising:

• sensing an obstruction in the first and second management processors;
• when the obstruction is sensed in one of the first and second management processors, marking a call processing information relating to the other one of the first and second management processors;
• and
• when the one is restored from the obstruction, dumping the marked call processing information from the one to the other one.

A method of controlling a plurality of management processors including first and second management processors of a portable internet RAS, comprising:

• (a-1)initializing the first management processor in an active state and the second management processor in an auxiliary active state;
• (a-2)sensing an obstruction in the first and second management processors;
• and
• (a-3)transiting the first management processor from the active state to an inactive state and transiting the second management processor from the auxiliary active state to a single active state when the obstruction is sensed in the first management processor.
