Communication control device, communication control method, communication system, and terminal device which takes into account at least one proximate multi-mode terminal serviced by a plurality of communication services

A communication control method performed by a communication control device configured to control a secondary communication service to be provided at an area where at least a part of coverage of the secondary communication service is overlapped with a coverage of a first primary communication service, the method comprising:

• at least one of:
• transmitting instructions to a terminal device to switch subscriber identity module (SIM) information corresponding to the first primary communication service to SIM information corresponding to a second primary communication service, or
• receiving information pertaining to the terminal device switching between the SIM information, and
• increasing a transmission power of the secondary communication service upon performing the switching from the subscriber identity module (SIM) information corresponding to the first primary communication service to the SIM information corresponding to the second primary communication service in the terminal device using a communication service by using any SIM information switched between a plurality of SIM information.

A communication system comprising:

• a terminal device configured to use a communication service by using any subscriber identity module (SIM) information switched between a plurality of SIM information corresponding to a plurality of primary communication services;
• and
• a communication control device configured to include:
• a CPU for controlling a transmission power of a secondary communication service to be provided at an area where at least a part of coverage of the secondary communication service is overlapped with a coverage of a first primary communication service;
• and
• communication interface configured to:
• transmit instructions to a terminal device to switch subscriber identity module (SIM) information corresponding to the first primary communication service to SIM information corresponding to a second primary communication service, or
• receive information pertaining to the terminal device switching between the SIM information,
• wherein the CPU increases the transmission power of the secondary communication service upon performing the switching from the SIM information corresponding to the first primary communication service to the SIM information corresponding to the second primary communication service in the terminal device.
