Abstract

A content providing system that provides content to a user terminal via a network includes a content providing server that is connected to the network and provides content, an SIP proxy server that is connected to the network and relays transmission and reception between the user terminal and the content providing server, and a monitoring server that is connected to the network and stores monitoring information regarding transmission and reception between the user terminal and the content providing server, the monitoring information being transmitted from the SIP proxy server.

Claims

1. A content providing system that provides content to a user terminal via a network, the content providing system comprising:

a content providing server that is connected to the network and provides content;

an SIP proxy server that is connected to the network and relays transmission and reception between the user terminal and the content providing server; and

a monitoring server that is connected to the network and stores monitoring information regarding transmission and reception between the user terminal and the content providing server, the monitoring information being transmitted from the SIP proxy server,

wherein the monitoring server determines a number of users at a regular time interval from a number of successes and a number of errors with respect to an INVITE method, and the monitoring server sends a notification regarding the number of the users to the content providing server that obtains a network bandwidth based on the notification; and

wherein the monitoring information includes a SIP method type, a SIP response type, and an IP address.

2. A monitoring server that is connected to a network to which a content providing server that provides content and an SIP proxy server that relays transmission and reception between a user terminal and the content providing server are connected, the monitoring server comprising:

a monitoring-information reception unit that receives monitoring information regarding transmission and reception between the user terminal and the content providing server, the monitoring information being sent from the SIP proxy server; and

a monitoring-information storage unit that stores the monitoring information received by the monitoring-information reception unit,

wherein the monitoring server further comprises a processing unit and a notification unit,

wherein the processing unit determines a number of users at a regular time interval from a number of successes and a number of errors with respect to an INVITE method, and the notification unit sends a notification regarding the number of the users to the content providing server that obtains a network bandwidth based on the notification; and

wherein the monitoring information includes a SIP method type, a SIP response type, and an IP address.

3. The monitoring server according to claim 2,

wherein the monitoring information is information regarding a SIP response transmitted from the content providing server to the user terminal in response to an SIP method transmitted from the user terminal to the content providing server.

4. An SIP proxy server that is connected to a network, to which a content providing server that provides content is connected, and relays transmission and reception between a user terminal and the content providing server, the SIP proxy server comprising:

a monitoring-information transmission unit that transmits, to a monitoring server that is connected to the network, monitoring information regarding transmission and reception between the user terminal and the content providing server,

wherein the monitoring server determines a number of users at a regular time interval from a number of successes and a number of errors with respect to an INVITE method, and the monitoring server sends a notification regarding the number of the users to the content providing server that obtains a network bandwidth based on the notification; and

wherein the monitoring information includes a SIP method type, a SIP response type, and an IP address.

5. The SIP proxy server according to claim 4,

wherein the monitoring information is information regarding an SIP response transmitted from the content providing server to the user terminal in response to an SIP method transmitted from the user terminal to the content providing server.
