Description

The present invention relates to a transmission management system that transmits a destination name in communication between transmission terminals to a transmission terminal.

2. Description of the Related Art In recent years, a video conference system has become widespread as an example of a transmission system that performs communication via a communication network in response to a request for reducing travel expenses and travel time. In the video conference system, communication of content data such as image data and audio data is performed between video conference terminals as an example of a transmission terminal, and a video conference can be realized.

When starting communication such as a video conference, there is known a method of requesting the start of communication by selecting a specific destination from a destination list indicating the names of candidate destinations (see Patent Document 1). ). In this method, a transmission management system that controls the start of communication creates a destination list indicating the names of candidate destinations, sends the destination list to the transmission terminal, and causes the transmission terminal to select a specific destination. As a destination name managed by the transmission management system, a geographical name such as "Japan", a business office name such as "Tokyo business office", or a terminal name such as "AB terminal" has been used.

However, the name of the destination that can be easily identified may differ depending on the communication. For example, when communication within the same organization uses the team name used within the organization as the destination name, or when communication between different organizations uses the company name as the destination name, it becomes easier to identify the destination. There is. In the conventional transmission system, since the common name is used as the name of the destination provided to each user, there arises a problem that the name of the destination corresponding to the communication cannot be provided.

In the invention according to claim 1, the first destination name information indicating the name of the destination corresponding to the identification information of the destination in the communication between the transmission terminals is stored in association with the identification information used for login, The second destination name information different from the first destination name information input from the transmission terminal that has accepted the reservation, and the second destination name information corresponding to the identification information of the destination is stored as the reservation of the communication. A destination name information management unit that stores the information in association with the destination, a receiving unit that receives a login request based on the identification information from a transmission terminal that can communicate with the destination, and the identification after the transmission terminal logs in based on a login request. Transmission means for transmitting first destination name information corresponding to identification information of the destination associated with information to the transmission terminal in association with the destination, and stored in the destination name information management means. The first destination name information and the second destination name information that are different from each other are destination name information different from the IP address of the transmission terminal, and the transmitting unit is configured to transmit the communication information identified based on the identification information. The management system is characterized in that the second destination name information corresponding to the identification information of the destination associated with the reservation is transmitted to the transmission terminal.

As described above, according to the present invention, the transmission management system manages a plurality of destination name information indicating the name of the destination for one destination, and at least one of the plurality of destination name information is managed. The destination name information is extracted and transmitted to the transmission terminal. In this case, since the transmission management system can manage the destination name information corresponding to the communication for one destination, it is possible to provide the destination name information according to the communication. Play.
