Dual communications network base station apparatus

A dual communications network base station apparatus comprising:

• a first UTRA (universal mobile telecommunications system (UMTS) terrestrial radio access) network, transmitting and receiving first data including pairs information via a previously set first communications band;
• a second UTRA network transmitting and receiving second data including the pairs information via a second communications band different from the first communications band;
• a core network combining the first data and the second data from the first and second UTRA networks by using the pairs information during wireless reception, dividing the first data and the second data including the pairs information according to a previously set division rate during wireless transmission, and providing the corresponding UTRA network with the divided first data and the divided second data;
• and
• a server communicating data including the first data and the second data with the core network.
