Abstract

A communication speed control system to be placed between service providing servers on the Internet and smartphones, the communication speed control system including: a traffic storing unit a non-regulated IP address storing unit for registering IP addresses of the servers a packet reading unit for extracting an IP address of the server from the packet; a traffic management unit for calculating cumulative data traffic of the IP address in question a handling rule management unit for determining that a band limitation is required when the cumulative data traffic exceeds a threshold value and the IP address in question is not registered as a non-regulated IP address, and determining that a band limitation is not required when the cumulative data traffic does not exceed the threshold value and a packet transmission unit for transmitting a packet at a normal communication speed.

Claims

1. A communication speed control system to be placed between a plurality of service providing servers arranged on the Internet and a plurality of mobile phones associated with a specific carrier, the communication speed control system comprising:

traffic storing means in which data traffic between the individual mobile phones and the individual service providing servers is successively stored in association with IP addresses of the service providing servers;

non-regulated IP address storing means for registering the IP addresses of specific service providing servers as non-regulated IP addresses in advance;

means for, when a packet is exchanged between a specific service providing server and a specific mobile phone, extracting an IP address of the service providing server from the packet;

means for calculating cumulative data traffic associated with the extracted IP address by reference to the traffic storing means;

means for, when this cumulative data traffic exceeds a predetermined threshold value, checking whether or not the IP address in question is registered as a non-regulated IP address by reference to the non-regulated IP address storing means;

means for determining that a band limitation is required when the cumulative data traffic associated with the IP address exceeds the threshold value and the IP address in question is not registered as a non-regulated IP address in the non-regulated IP address storing means, and determining that the band limitation is not required when the cumulative data traffic does not exceed the threshold value, or when the IP address in question is a non-regulated IP address even if the cumulative data traffic exceeds the threshold value; and

means for transmitting a packet toward a destination at a normal communication speed when the band limitation is not required, and transmitting the packet toward the destination at a slower speed than normal when the band limitation is required.

2. The communication speed control system of claim 1, further comprising communication log acquisition means for successively storing date and time of the packet transmission, the data traffic, and the IP address of the service providing server in the traffic storing means.
