Abstract

PURPOSE:To eliminate the need for the user to make redialing for many number of times while the throughput is decreased till a throughput secured by a network by revising the throughput to a throughput to be secured by a network so as to make call connection with an incoming user when the network cannot secure the throughput requested by the caller user. CONSTITUTION:When a call is given from a packet terminal (a) to a packet terminal (c), a caption (e) is a CR packet of the packet terminal (a) and the throughput is 4.8kbps. A caption (f) is a CR packet whose throughput is selected to be 2.4kbps secured between packet exchanges A, B, the throughput is revised to 2.4kbps and a CN packet (g) (throughput is 2.4kbps) is used for negotiation with the packet terminal (c). The result is informed to the packet terminal (a) by using a CA packet (h) and CC packets i, j. The packets h, i, j have the throughput of 2.4kbps.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はパケット交換網の呼接続制御方式に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a call connection control method for a packet-switched network.

〔従来の技術〕[Conventional technology]

従来、パケット交換網におけるスループットネゴシェー
ションは、ユーザ間で行われ、発ユーザから要求された
スループット値を網が確保できない場合には、網は呼接
続を拒否するようになっていた。Conventionally, throughput negotiation in a packet-switched network was performed between users, and if the network could not secure the throughput value requested by the calling user, the network would reject the call connection.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

このように発ユーザから要求されたスループット値を網
が確保できない場合には、網は呼接続を拒否するため、
発ユーザは網が確保できるスループット値までスループ

いう問題がある。In this way, if the network cannot secure the throughput value requested by the calling user, the network will reject the call connection.
There is a problem in that the calling user has to call again many times while lowering the throughput value to a throughput value that can be secured by the network.

〔課題を解決するための手段〕[Means to solve the problem]

本発明のパケット交換網の呼接続制御方式は、発ユーザ
が要求するスループット値をパケット交換網が確保でき

ト値に変更して相手ユーザと呼接続を行う構成である。The call connection control method for a packet-switched network of the present invention is configured such that when the packet-switched network cannot secure the throughput value requested by the calling user, the throughput value is changed to the throughput value that can be secured by the packet-switched network and the call is connected to the other user. It is.

FIG. 3 is a diagram illustrating a call connection sequence when a call is made to . Here, e is a CR packet of terminal a, and the throughput is 4.8 Kbps. f is a CR packet when the throughput that can be secured between packet switches A and B is 2.4 Kbps, the throughput is changed to 2.4 Kbps, and the CN packet (throughput 2.4 Kbps
) Negotiate with terminal C using g, and the result is terminal a using CA packet h and CC packets i and j.
will be notified. Packets h, i, and j have a throughput of 2.
It is 4Kbps.
