Relay apparatus, relay method, and storage medium

A mobile communications system comprising:

• a first relay apparatus that relays communications between donor-cell base stations and a relay base station;
• and
• mobile networks respectively corresponding to a plurality of the respective donor-cell base stations to which the first relay apparatus connects,
• wherein each of the mobile networks includes a second relay apparatus that relays communications between a first core network which communicates with the donor-cell base stations, and a second core network which communicates with an external network;
• wherein the first relay apparatus includes:
• a first communication unit that receives uplink data associated with first identification information from a terminal device;
• and
• a division integration unit that determines to transmit the uplink data to the mobile network which is associated with the first identification information, among a plurality of the mobile networks;
• and
• wherein the second relay apparatus includes:
• a converter that converts a first parameter, which is included in the uplink data received from the first core network, into a second parameter on the basis of the first identification information;
• and
• a second communication unit that transmits the uplink data including the second parameter to the second core network associated with the first identification information.
