AI Technical Summary

Problems solved by technology

Additionally, part of the identity information must be spent on site information
This causes problems such as a reduction in the portion allocated to wireless terminals and difficulty in accommodating an increase in the number of users
[0010] Also, if each site in the network includes multiple controllers, the process of knowing which controller manages the identification information is complicated
Then, it can be expected that the response characteristics from each site will be degraded and users will not receive adequate service

Embodiment Construction

[0044] figure 1 is a connection diagram of the roaming system according to the first embodiment of the present invention. figure 2 is the block diagram showing the controller. image 3 is a diagram showing an exemplary configuration of the server 20 .

[0045] The wireless network includes multiple stations, and each station corresponds to an area Z with a radius of several kilometers to tens of kilometers around the base station. Each base station has any number of controllers 10 . These controllers 10 are interconnected by a network N.

[0046] The controller 10 of the base station timely accepts information transmitted to and receives information from wireless terminals existing in the corresponding station. Performing data communication between the controllers 10 of these sites realizes a so-called wide area network.

[0047] Each wireless terminal is registered in its home site. The area where the wireless terminal usually resides is the main site of the wireless t...

Abstract

There is provided a system for judging validity of a radio terminal according to identification information on the radio terminal and providing a service. A radio network is divided into a plurality of zones. For each of the zones, there is arranged a server for storing in a particular zone, the position of the directory containing identification information on each radio terminal without storing identification information on the radio terminal registered in other zone. By communication between the server and zone controllers, the identification information on the radio terminal is confirmed and a service is provided. Thus, it is possible to realizing a roaming system capable of performing an ideal roaming without increasing the volume of the system resource.

Description

technical field [0001] The invention relates to data communication in a wireless network, in particular to a roaming system, a mobile communication system and a mobile communication control method. Background technique [0002] A wireless network includes multiple sites, and each site corresponds to an area with a radius of several kilometers to tens of kilometers around the base station. The base station in each station promptly accepts information transmitted to and receives information from wireless terminals present in the station. Data communication is performed between base stations at these sites to realize a so-called wide area network. [0003] Each wireless terminal is registered with its home site. The area where the wireless terminal usually resides is the main site of the wireless terminal. Once a wireless terminal has a certain area as its home site, servers belonging to the corresponding base station can provide services available in the site. [0004] In ...
