2. Description of the Related Art In recent years, with the increase in communication needs and the development of communication technology, information communication such as television telephone communication has been performed between a plurality of communication terminal devices using an information communication network such as a public telephone network or the Internet. Performing systems are widespread.

By the way, a communication terminal device used in this type of system generally starts transmission with a communication terminal device of the other party at the time of transmission speed, coding method, image format, and per unit time. Attribute information such as the number of transmission frames is transmitted and received between the own terminal and the partner terminal. Then, the attribute information of the partner terminal obtained thereby is compared with the attribute information of the own terminal to determine common attribute information, and communication is performed by setting the common attribute information as a parameter.
International standards for communicating this attribute information include, for example, H.264 of ITU-T. 245.

[0004]

[0005] However, this H.264 standard has a problem. 24
The communication procedure represented by 5 is defined so as to correspond to various kinds of communication, so that the structure is complicated and communication messages are redundant. For this reason, transmitting and receiving the attribute information every time communication is started causes a long negotiation time to reduce the use efficiency of the system, and the user has to bear extra communication costs. It is not preferable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to reduce the time required for negotiation to improve the use efficiency of the system and reduce the burden of communication costs on the user. A communication system and a communication terminal device thereof are provided.

[0006]

In order to achieve the above object, a communication terminal device according to the present invention stores own terminal identification information storage means for storing own terminal identification information, and stores attribute information of the own terminal. In addition to the self-terminal attribute storage unit, the communication terminal includes a partner information storage unit that stores identification information of a communication partner and attribute information of the communication partner in association with each other, and a parameter setting unit. Prior to the communication with the communication partner, the parameter setting means reads the attribute information of the communication partner from the partner information storage means, and stores the attribute information of the communication partner and the attribute information stored in the own terminal attribute storage means. The configuration is such that parameters are set based on the attribute information of the terminal.

With this configuration, each communication terminal device sets parameters using the attribute information of the communication partner stored in the partner information storage means of the communication terminal device in advance. Therefore, there is no need to transmit and receive the attribute information to and from the communication partner, which greatly reduces the time required for negotiation.

In the invention, the parameter setting means may further include a judgment means for judging whether or not attribute information of the communication partner is stored in the other party information storage means, and an attribute information learning means. If it is determined that the attribute information of the communication partner is not stored, a procedure for acquiring the attribute information of the communication partner with the communication partner is executed, and the acquired attribute information is stored in the communication partner. It is also characterized in that the information is stored in the partner information storage means in association with the identification information.

With this configuration, when the attribute information of the communication partner is not stored in the partner information storage means, the attribute information is acquired from the communication partner, and the attribute information is stored in the partner information storage device of the own device. It is newly stored in the means. That is, with this learning function, the attribute information of the partner information storage means is enhanced every time communication is performed.

Further, according to the present invention, when the attribute information learning means determines that the attribute information of the communication partner is not stored by the determining means, the attribute information of the own terminal is read from the own terminal attribute storage means. It is also characterized in that it is transmitted to a communication partner.

With this configuration, the acquisition of the attribute information from the communication partner terminal device and the storage of the attribute information of the own terminal in the partner terminal device are simultaneously performed. Usually, when the attribute information of the communication partner is not stored in the own terminal, the attribute information of the own terminal is often not stored in the communication partner. Therefore, as described above, by transmitting the attribute information of the own terminal to the communication partner at the same time as the acquisition of the attribute information from the communication partner, efficient attribute information management as a whole system becomes possible.

Further, according to the present invention, the partner information storage means comprises a first storage section and a second storage section, and the first storage section divides the attribute information into a plurality of groups and stores these groups. The second storage unit stores the attribute information identifier of the attribute information group of the communication partner in association with the identification information of the communication partner, while storing the attribute information identifier in association with the attribute information identifier for identifying the group. Features.

With this configuration, when the communication partner has a plurality of attribute information groups, these attribute information groups can be registered in association with one communication partner.

By providing such means, attribute information can be transmitted and received between communication terminal devices using a time zone where the traffic of the information communication network is relatively low, such as at night, for example. New attribute information is stored.

On the other hand, an information communication system according to the present invention comprises a plurality of communication terminal devices interconnected via an information communication network, and information information connected to these communication terminal devices via the information communication network. A management device, wherein the information management device stores attribute information of the plurality of communication terminal devices in association with the identification information of the communication terminal device, and stores attribute information from the communication terminal device. When an inquiry for acquisition arrives, attribute information notifying means for reading the corresponding attribute information from the attribute information storage means according to the content of the inquiry and notifying the communication terminal device of the inquiry source is provided, and Prior to the communication with the communication partner, the communication terminal device sends the inquiry for acquiring the attribute information of the communication terminal device as the communication partner to the information management device. Sent to and is characterized in that a parameter setting means for setting based on the parameter and the attribute information of the attribute information and the own terminal notified from the information management apparatus to the inquiry.

[0017] With this configuration, when the attribute information of the communication partner is unknown, each communication terminal device can acquire the attribute information of the desired communication partner from the information management device and set parameters. .

According to the present invention, the communication terminal further includes means for sending a request for registration of attribute information to the information management device, and the information management device receives a request for registration of attribute information from the communication terminal. In this case, a means for storing attribute information in the attribute information storage means in response to the request is further provided. With this configuration,
Attribute information can be registered in the information management device from each communication terminal device. Therefore, for example, when trying to transmit the attribute information of the own terminal to the partner terminal, when the partner terminal is in use or when the partner terminal is not activated due to power-off or the like, the attribute information of the own terminal is compared with the partner terminal. It becomes possible to transmit and register to the information management device instead of the terminal.

Next, the operation of the apparatus configured as described above will be described. Here, a case will be described as an example where communication terminal device TM11 performs communication for a videophone with communication terminal device TM21.

In the setup sequence before starting communication, the communication terminal device TM11 firstly transmits its own terminal identification information to the communication partner terminal device TM21, and sends a request for transmission of the identification information. In response, the terminal device TM21 of the communication partner returns the identification information of the terminal itself.

During the communication after the completion of the setup, the identification information may be transmitted from the communication partner terminal device TM21 without transmitting the identification information transmission request from the communication terminal device TM11.

When the identification information arrives from the terminal device TM21 of the communication partner, the communication terminal device TM11 accesses the partner terminal identification / attribute information storage unit 103 by the operation attribute determining unit 104, and identifies the identification information of the terminal device TM21 of the communication partner.
