The present invention provides an Internet address and a radio resource to a mobile data host in a next generation mobile communication network when the Internet is required as a mobile data host of a next generation mobile communication (IMT-2000) network subscriber. Traffic channel) to provide an Internet service.

In general, the transmission control protocol / network protocol (TCP / IP) and routing technologies used in Internet services are designed under the assumption that the host (computer) and routers that perform Internet services are always fixed and move the host. Changes to protocols and routers are required to apply to communication environments.

In the conventional technology of accessing the Internet to a mobile data host requiring mobility, a matching device performing an agent function in a network is moved when a fixed Internet address is given to the mobile data host and an Internet connection is required to the mobile data host. Finding the location of a data host and routing it using a tunneling technique to connect to the mobile data host using a fixed (static) internet address assignment method, and the mobile data host without a fixed internet address If the mobile data host moves to a specific area by assigning the name of, the agent managing the area assigns an Internet address, and when the mobile data host requests the Internet connection using a fixed name, the network matching device corresponds to the name. To provide Internet access Dynamic Internet address allocation method was proposed.

They transmit data over packet-switched connection-less connections and are suitable for use in networks with narrow wireless areas, such as computer networks.

When the mobile data host enters the wireless communication area using the dynamic Internet address allocation method, it connects to the mobile router's subnetwork through the connection between the mobile access station and the mobile data host managing the area. The Internet address of the mobile data host is given by merging the assigned network address with the host number assigned by the mobile router. At this time, when the Internet host requests the mobile data host to access the Internet, the Internet service is provided using the Internet address assigned to the mobile data host (the Internet address is always assigned).

The prior art as described above is suitable for providing an Internet service to a mobile data host in an environment in which a wireless control area (cell) uses only a small number of narrow Internet addresses. However, since the wireless control area is narrow, the frequent load registration process and handover process are required during the movement of the mobile data host (eg, while the vehicle is in operation), thereby increasing the load of the system and degrading service quality.

In other words, if the conventional technology described above is applied to a next-generation mobile communication system that simultaneously provides a voice service and a data service requiring reliability by using limited radio resources and insufficient Internet addresses in a wide radio area (cell), the performance of the system may be improved. There is a problem in that it is not possible to provide Internet services to most mobile data hosts.

The present invention has been made in order to solve the above-mentioned problems. In the case where the Internet host attempts to access the Internet with the mobile data host owned by the subscriber of the mobile communication network, the mobile data is transmitted using the mobile subscriber's mobile phone number in the mobile communication network. An object of the present invention is to provide a method of providing Internet address assignment and Internet incoming service in a next-generation mobile communication network that provides an Internet service by searching or assigning an Internet address dynamically allocated to a host and efficiently using a traffic channel.
