System and method for reduced interruption time in mobile communications

A method for a base station to reduce a communication interruption time of one or more mobile communication devices that are communicating with a core network through the mobile communication base station when the mobile communication base station is stopping operation, the method comprising:

• determining that the base station is stopping operation;
• switching to a backup power source if the base station is stopping operation due to loss of power;
• and
• transmitting a message to the mobile communication devices connected to the base station that they should switch to a fallback cell, since the base station is stopping operation.

A mobile communication device wirelessly connected to a cell operated by a base station, the mobile communication device comprising:

• a radio module configured to establish a wireless connection to a cell;
• a processor;
• and
• a memory, the memory comprising a set of instructions that when executed by the processor cause the mobile communication device to:
• determine a fallback cell;
• obtain parameters to quickly establish a wireless connection to the fallback cell;
• determine that the base station is stopping operation;
• and
• use the parameters to quickly establish a wireless connection to the fallback cell.

A base station of a mobile communication system comprising:

• a radio module configured to communicate wirelessly with one or more mobile communication devices;
• a network interface configured to communicate with a core network;
• a backup power source;
• a processor;
• and
• a memory, the memory comprising a set of instructions that when executed by the processor cause the base station to:
• determine that the base station is stopping operation;
• switching to the backup power source if the base station is stopping operation due to loss of power;
• and
• transmit a message to the mobile communication devices communicating with the base station that they should switch to a fallback cell, since the base station is stopping operation.
