Control apparatus, signal transmission system and control method

A signal transfer system comprising:

• one or more base stations configured to accommodate one or more wireless terminals;
• one or more transfer devices configured to transfer uplink communication of the one or more wireless terminals received via the one or more base stations to an upper side;
• a transfer device controller configured to controls the one or more transfer devices;
• an information acquirer configured to acquire wireless control information related to wireless communication between the one or more base stations and the one or more wireless terminals for each of traffic flows from the one or more wireless terminals to an upper device;
• a control determiner configured to estimate a delay value occurring in a wireless section for each of packets on a basis of the wireless control information acquired for each of the traffic flows, and performs a delay control instruction for executing adjustment processing of adjusting a packet interval of a plurality of packets by adding a delay to each of the packets using the estimated delay value for each of the packets;
• and
• a delay controller configured to execute the adjustment processing in accordance with the delay control instruction of the control determiner.

A control method performed by a transfer device controller in a signal transfer system including one or more base stations that accommodate one or more wireless terminals, one or more transfer devices that transfer uplink communication of the one or more wireless terminals received via the one or more base stations to an upper side, and a transfer device controller that controls the one or more transfer devices, the control method comprising:

• acquiring wireless control information related to wireless communication between the one or more base stations and the one or more wireless terminals for each of traffic flows from the one or more wireless terminals to an upper device;
• estimating a delay value occurring in a wireless section for each of packets on a basis of the acquired wireless control information for each of the traffic flows;
• and
• performing a delay control instruction for executing adjustment processing of adjusting a packet interval of a plurality of packets by adding a delay to each of the packets using the estimated delay value for each of the packets.
