Description

Information service network systems and information service methods.

The present invention relates to a service network system and a service method thereof, and more particularly, to an information service network system and an information service method for transmitting predetermined service information to a user terminal through a network.

In general, the configuration of the information service network system is in accordance with the configuration shown in FIG. 1 is a block diagram of a conventional information service network system. Here, the information service network system is composed of a network management server 100, terminals 110, ... N, and servers 130, ... M. The network management server 100 manages the terminals 110,... N and servers 130,... M on the network, and the servers 130,... Connect it. If the communication environment on the network is a TCP / IP environment, SNMP (Simple Network Management Protocol) is used as the network management protocol. If the OSI environment, CMIP is used as the network management protocol. In order to use a network management protocol such as SNMP or CMIP, not only the network management server 100 but also each terminal (110, ... N) is a kind of management in which items of information flowing in a network transmission path called a management information base (MIB) are defined. The information databases 101, 111, n are stored so that the information on the network is transmitted in accordance with the information in the management information database. The terminals 110,... N request data to be transmitted through the network, and display the data on an output device such as a monitor when the data is transmitted. On the network using the network management protocol such as SNMP or CMIP, the daemon handlers 112 and n + 2 that execute the SNMP or CMIP communication protocol should be installed in the terminal. The servers 130, ... M are computers that provide the services of the servers 130, ... M themselves to the terminals 110, ..., N on the network.

Terminals 110, ... N, which are connected on the network and receive information from the servers 130, ... M, are directly connected to the user, such as a TV receiver receiving video information from a cable TV station. It is designed to have a relatively small amount of memory without a disk to reduce the price because it is a device to be burdened, but as described above, the memory burden according to the MIB (101, 111, n) storage and network management protocols such as SNMP or CMIP There is bound to be a CPU burden due to the daemon processors 102 and n + 1 running. The addition of memory and the use of high-performance CPUs are important factors in raising handset prices. In addition, protocols such as SNMP and CMIP do not allow changes, additions, and deletions on MIBs (101, 111, n), which are network management items, on the network. There was a problem that it was difficult to take information from the server (130, ... M).

The present invention has been made to solve the above problems, the network management protocol and the network management database and its protocol processor is transmitted online when the network is connected without the resident in the terminal, thereby reducing the memory and CPU burden of the terminal The object of the present invention is to provide an information service network system and an information service method that can easily change a network protocol and its management database.
