Abstract

PURPOSE:To set an optimum call and to economize communication fee and to prevent transmission delay by informing transmission quantity to be communicated and data length to a gateway device beforehand. CONSTITUTION:When a user A on a local area network LAN 1 communicates with the user B on a packet switching network 5 through the gateway device 2, the transmission quantity to be communicated, its data length and other information necessary for setting a call are exchanged between the communicating means 3 of the user A on the LAN 1 and the communicating means 4 of the gateway device 2, and the gateway device 2 sets the call between the user A and the user B according to this information. Thus, the call can be set by the optimum data length, and the transmission delay can be prevented.

Description

法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a method for setting up a call to a packet switching network, and in particular to a gateway that interconnects a local area network (hereinafter referred to as LAN) and a packet switching network. The present invention relates to a method for setting up a call that a device performs to a packet switching network.

要である。In the above gateway device, when communicating data from the LAN via the packet switching network, it is necessary to set up a call with the other party on the packet switching network.

かった。In the pricing system of a packet-switched network, large-sized data becomes cheaper when a call is set up and communicated by negotiating a larger data length. However, in the conventional technology, a call is set up with a fixed data length, so there is a problem that data of various lengths cannot be handled advantageously in terms of charges. Furthermore, like charges, propagation delays in a packet-switched network vary depending on call setup, and conventional techniques lack flexibility in this regard as well.
