Problems solved by technology

In particular, 3G (Third Generation: Third Generation) services using the 2GHz frequency band have insufficient electromagnetic wave propagation characteristics compared to 2G (Second Generation: Second Generation), and indoor areas that become blind spots will increase.
[0003] In this situation, in order to make the indoor area of ​​3G service equal to that of 2G service, it is necessary to introduce many indoor systems, but it is difficult to implement in terms of cost because many mobile communication operators need to be equipped accordingly

Embodiment Construction

[0106] use figure 1 with figure 2 The shown network structure diagram illustrates the mobile communication system in the first embodiment of the present invention. The LAN 20, which is a private network connected to a personal computer (PC) 110, etc., is constructed of Ethernet(R) (registered trademark) (Ethernet(R)), passes through a firewall 900, and a VPN (Virtual Private Network) gateway as a relay node. Way) 100 and connected to the Internet 10. On the other hand, the mobile communication core network 30 is connected to the Internet 10 via a radio base station control station (radio base station control station: referred to as Radio Network Controller) 70 and a mobile network gateway 120.

[0107] The wireless base stations 60 to 63 are connected to the LAN 20 as a private network (a private network, such as a network privately constructed by a company or the like), so that when communicating between the wireless base station control station 70 and the wireless base station...

Abstract

When a mobile terminal (80) calls or is called, a VPN gateway (100) as a relay node which has received the mobile communication control signaling judges reception in linkage with a policy server (200) as a band control mechanism in a LAN (20) which is a private network. When the reception is permitted, the communication line is provided to the mobile terminal (80) or a preparatory shared key is dynamically generated by a key exchange mechanism between a radio base station and a radio base control station (70) and the radio base control station (70) reports the preparatory shared key to the VAN gateway (100).

Description

Technical field [0001] The present invention relates to a mobile communication system that is composed of a wireless base station control station and a wireless base station connected to the wireless base station control station and provides mobile communication services to mobile terminals that can be connected to the wireless base station. A mobile communication system that provides mobile communication services to of users. In addition, it also relates to a relay node and a radio base station control station used in the mobile communication system, as well as a program and a mobile communication method for realizing the functions of the mobile communication system, the relay node, and the radio base station control station. Background technique [0002] In a mobile communication system, it is difficult for electromagnetic waves to reach indoors such as buildings, so users who use mobile terminals indoors cannot receive stable mobile communication services. In order to provide ...
