Patent ID: 8320268

Claim:
A communication control apparatus for controlling a communication path for a radio communication apparatus by using a first radio IP network which dynamically assigns a first care-of IP address to the radio communication apparatus according to a position of the radio communication apparatus, and a second radio IP network which assigns a second care-of IP address to the radio communication apparatus, the communication control apparatus comprising: a relay configured to receive IP packets transmitted at predetermined intervals from the radio communication apparatus to a communication destination via the first radio IP network and via the second radio IP network, and to relay the received IP packets to the communication destination; an uplink bandwidth ratio calculator configured to calculate an uplink bandwidth ratio based on a received number of the IP packets from the first radio IP network and the second radio IP network received by the relay from the radio communication apparatus within a monitoring period, the uplink bandwidth ratio indicating a ratio of a bandwidth of the first radio IP network to a bandwidth of the second radio IP network, receiving the IP packets between completion of the monitoring period and completion of a next monitoring period based on the bandwidths of the first and second radio IP networks within the monitoring period; and an uplink transmission controller configured to transmit, to the radio communication apparatus, uplink bandwidth ratio information from which the uplink bandwidth ratio calculated by the uplink bandwidth ratio calculator is contained within.
