Summary: | To provide a communication system capable of coping with an increase in the number of billing separations.SOLUTION: A communication system comprises: a communication terminal; a relay device that relays communication between the communication terminal and a server; and the server. Each of the relay device and the server stores a first table that associates a billing separation ID for identifying a billing destination for a packet communication charge with a transmission source port number of the communication terminal. When performing packet transmission, the communication terminal, on the basis of the first table and a second table that associates an application ID of each of a plurality of applications with a billing separation ID, transmits a packet including a transmission source port number corresponding to a billing separation ID associated with an application ID. The relay device identifies a billing separation ID associated with the transmission source port number identified on the basis of port number information contained in the packet received from the communication terminal; and generates a billing record associating the identified billing separation ID with the number of received packets.SELECTED DRAWING: Figure 1
【課題】課金分離数の増大に対応可能な通信システムを提供する。【解決手段】通信端末と、通信端末とサーバとの間の通信を中継する中継装置と、サーバとを備える通信システムであって、中継装置及びサーバは、パケット通信料金の課金先を識別する課金分離IDと、通信端末の送信元ポート番号とを対応付けた第1テーブルをそれぞれ記憶し、通信端末は、パケット送信する際に、第1テーブルと複数のアプリケーションそれぞれのアプリケーションIDと、課金分離IDとを対応付けた第2テーブルとに基づいて、アプリケーションIDと関連付けられた課金分離IDに対応する送信元ポート番号を含むパケットを送信し、中継装置は、通信端末から受信したパケットに含まれるポート番号情報に基づき特定した送信元ポート番号と対応づけられた課金分離IDを特定し、特定した課金分離IDと受信パケット数とを関連づけた課金レコードを生成する。【選択図】図1 |
