Network connection communication system

A network connection communication system that provides selected services using one or more communication terminals through a connection over a choice of a plurality of networks, the system comprising:

• one or more processors;
• and
• memory, including instructions executable by the one or more processors to cause the system to at least provide:
• a display screen on a communication terminal including:
• a set of buttons for selecting a first network from the plurality of available networks, and an indicator for displaying a balance of usage units for a corresponding service;
• a connection unit for establishing connections for the communication terminals over the plurality of networks based on the number of available usage units for the corresponding service;
• a time management means for modifying and managing the number of usage units for the corresponding service that are ready for use or already used for the communication terminal;
• a unit converter for converting and modifying the number of usage units for the corresponding service based on usage over connections established within the plurality of networks;
• and
• a database for storing a plurality of communication coefficients for connections over the plurality of networks, wherein the plurality of communication coefficients may reduce or increase the number of usage units for the corresponding service in view of existing network conditions among the plurality of networks;
• wherein the unit converter, upon a change of a second network to be used, converts the number of usage units of the service by employing at least two communication coefficients from the plurality of communication coefficients relating to the second network, the converted number of usage units of the service being on the display screen on the first terminal;
• wherein the control unit, the time management unit, the unit converter, and the database are stored in the memory;
• wherein the usage units of the corresponding service are in the form of a number of times of allowed network connections with a partner with whom communication is desired over the connection;
• and
• wherein the at least two communication coefficients comprise at least two of the following:
• a service type that includes electronic mail service or web browsing service,
• a communication scheme type that includes a wired network type or a wireless network type,
• a terminal type that includes a PC-type or a non-PC type, and
• a network utilization ratio indicative of a degree of network congestion.
