Gateway apparatus and system

A system comprising:

• a monitoring apparatus;
• a gateway apparatus;
• and
• a plurality of base stations apparatuses connected to the monitoring apparatus via the gateway apparatus, wherein
• the monitoring apparatus transmits second configuration information for the plurality of base stations apparatuses via a first inter-device interface configured to communicate with the gateway apparatus,
• the gateway apparatus has a memory and a processor coupled to the memory, the processor configured to generate first configuration information when the second configuration information is received from the monitoring apparatus, the processor generating the first configuration information by performing protocol conversion of converting the second configuration information into a format adapted to a second inter-device interface for the plurality of base station apparatuses, the processor further configured to transmit the generated first configuration information to the plurality of base station apparatuses via the second inter-device interface,
• the processor is further configured to divide the plurality of base station apparatuses into predetermined groups, the processor transmitting the second configuration information to the plurality of base station apparatuses at a different timing for each of the groups, and
• the plurality of base station apparatuses controls communications with subordinate terminal apparatuses based on reception of the first configuration information received from the gateway apparatus.
