Abstract

A mobile communication system is disclosed which comprises: an information terminal unit; a plurality of mobile stations, each of which communicates with the information terminal unit; a packet mobile switching center which communicates with the plurality of mobile stations through a radio access network; a packet mobile gateway switching center which communicates with the packet mobile switching center through a mobile data network; and a content server which communicates with the packet mobile gateway switching center through the Internet; wherein the information terminal unit downloads or uploads data from or to the content server through the plurality of mobile stations.

Claims

1. A mobile communication system, comprising:

an information terminal unit;

a plurality of mobile stations, each of which communicates with said information terminal unit;

a packet mobile switching center which communicates with said plurality of mobile stations through a radio access network;

a packet mobile gateway switching center which communicates with said packet mobile switching center through a mobile data network; and

a content server which communicates with said packet mobile gateway switching center through the Internet;

wherein said information terminal unit downloads or uploads data from or to said content server through the plurality of mobile stations.

2. An information terminal unit which communicates with a plurality of mobile stations,

wherein said plurality of mobile stations communicate with a packet mobile switching center through a radio access network,

wherein said packet mobile switching center communicates with a packet mobile gateway switching center through a mobile data network,

wherein said mobile gateway switching center communicates with a content server through the Internet, and

wherein said information terminal unit downloads or uploads data from or to said content server through said plurality of mobile stations.

3. A first mobile station which communicates with an information terminal, while at least a second mobile station communicates with said information terminal,

wherein at least said first and second mobile stations communicate with a packet mobile switching center through a radio access network,

wherein said packet mobile switching center communicates with a packet mobile gateway switching center through a mobile data network,

wherein said mobile gateway switching center communicates with a content server through the Internet, and

wherein said information terminal unit downloads or uploads data from or to said content server through at least said first and second mobile stations.

4. A packet mobile switching center which communicates with a plurality of mobile stations through a radio access network,

wherein said plurality of mobile stations communicate with an information terminal unit,

wherein said packet mobile switching center communicates with a packet mobile gateway switching center through a mobile data network,

wherein said mobile gateway switching center communicates with a content server through the Internet, and

wherein said information terminal unit downloads or uploads data from or to said content server through the plurality of mobile stations.

5. A packet mobile gateway switching center which communicates with a packet mobile switching center through a mobile data network,

wherein said packet mobile switching center communicates with a plurality of mobile stations through a radio access network,

wherein said plurality of mobile stations communicate with an information terminal unit,
