摘要:
A data communication system and data communication method capable of drastically improving the quality of a dynamic image service to be offered to a user. The data communication system comprises a mobile communication terminal (1-2), an application server (1-1) for fetching data open to the public on a network (1-7) in accordance with a request from the mobile communication terminal (1-2) and conducting a data rate conversion for delivery to the mobile communication terminal (1-2) and conducting data delivery and transferring the fetched data to a predetermined transferred destination, and a home server (1-5) provided in a base of a possessor of the mobile communication terminal (1-2) for receiving the data, fetched by the application server (1-1) and transferred, through the network (1-7) and accumulating the data to regenerate the data as needed.

摘要:
Concentrated use of wireless resources by location registrations carried out by slave mobile stations all together when a plurality of slave mobile stations present in a moving body provided with a master mobile station while bridging adjacent location registration areas is prevented. For this purpose, a mobile communications system 1 comprises: at least a broadcast information transmitting function unit (21) for notifying to the slave mobile stations (3) that the slave mobile stations are slaved to the master mobile station (2), a link maintaining function unit (31) for holding master-slave relationships, home location registers (5, 6) provided with expansion areas (52, 62) for holding the mobile station link information, and a mobile station link information forwarding function unit (41) for forwarding the address information of the master mobile station (2).
摘要:
A mobile unit transmits a request for position registration to a network when moving from a first area to a second area. When the number of incoming calls does not exceed a threshold and the number of movements between the first area and the second area exceeds a threshold, a mobile switchboard combines the first area and the second area into an extended area, and informs the mobile unit of the extended area.

摘要:
An access network selection method in a communications network having access networks is disclosed that includes notifying devices in calling-side and called-side networks of the identifiers of currently available access networks and user preferences; making a list of candidates for an access network to be assigned to the called-side terminal, and transmitting the list to the device in the calling-side network; determining an access network to be assigned to the calling-side terminal in response to reception of the list, and notifying the calling-side terminal of the determined access network; notifying the device in the called-side network of the type of the access network assigned to the calling-side terminal; and determining the access network to be assigned to the called-side terminal in response to reception of the signal of the type of the access network assigned to the calling-side terminal, and notifying the called-side terminal of the determined access network.
