Abstract

To create a network that connects a plurality of radio systems to create optimal systems for various environments, and that seamlessly integrates the resulting systems together in order to provide more efficient and advanced service in general. A basic access network 11 enables communication 13 between a basic access component provided in a mobile host 10 and widely disposed basic access network base stations, and comprises a basic access network channel implemented with a two-way radio interface and a basic access network protocol also used by a common core network of the network system.

Claims

1. A network system that seamlessly integrates radio systems, the system being characterized in that a basic access network enables communication between a basic access component provided in a mobile host and widely deployed basic access network base stations, and

comprises a basic access network channel implemented with a two-way radio interface;

and

a basic access network protocol to communicate with the common core network or-the rest of the integrated network.

2. A seamless integrated network system for radio systems according to claim 1, characterized in that a mobile host in said basic access network comprises:

only a basic access component, or comprises the basic access component, as well as

a radio module that can be connected to at least two other radio systems, a locator, a controller, and a user interface, and

the basic access component is formed by software radio or hardware.

3. A seamless integrated network system for radio systems according to claim 1, characterized in that:

said basic access network has transmission base stations and reception base stations disposed therein;

each of said transmission base stations transmits downlink data to the basic access component provided in the mobile host located in an area within a radius of several to several tens of kilometers of the transmission base station, and

each of said reception base stations receives uplink data from the basic access component provided in the mobile host located in an area within a radius of several to several tens of kilometers of the reception base station.

4. A seamless integrated network system for radio systems according to claim 2, characterized in that:

said basic access network has transmission base stations and reception base stations disposed therein;

each of said transmission base stations transmits downlink data to the basic access component provided in the mobile host located in an area within a radius of several to several tens of kilometers of the transmission base station, and

each of said reception base stations receives uplink data from the basic access component provided in the mobile host located in an area within a radius of several to several tens of kilometers of the reception base station.

5. A seamless integrated network system for radio systems according to claim 1, characterized in that:

said basic access network has at least one, a combination, or all of;

a function for invoking said mobile host;

a function for processing a notification of locational information from said communication terminal;

a function for notifying said mobile host of minimum information based on the locational information and required to find a radio system; and

a function for supporting minimum information particularly required by the mobile host to perform handover with a heterogeneous radio system.

6. A seamless integrated network system for radio systems according to claim 2, characterized in that:

said basic access network has at least one, a combination, or all of;

a function for invoking said mobile host;

a function for processing a notification of locational information from said communication terminal;

a function for notifying said mobile host of minimum information based on the locational information and required to find a radio system; and

a function for supporting minimum information particularly required by the mobile host to perform handover with a heterogeneous radio system.

7. A seamless integrated network system for radio systems according to claim 3, characterized in that:

said basic access network has at least one, a combination, or all of;

a function for invoking said mobile host;

a function for processing a notification of locational information from said communication terminal;

a function for notifying said mobile host of minimum information based on the locational information and required to find a radio system; and

a function for supporting minimum information particularly required by the mobile host to perform handover with a heterogeneous radio system.

8. A seamless integrated network system for radio systems according to claim 4, characterized in that:

said basic access network has at least one, a combination, or all of;

a function for invoking said mobile host;

a function for processing a notification of locational information from said communication terminal;

a function for notifying said mobile host of minimum information based on the locational information and required to find a radio system; and

a function for supporting minimum information particularly required by the mobile host to perform handover with a heterogeneous radio system.
