[0001]

[0001] The present invention relates to a radio base station apparatus directly connected to an existing public communication network.

[0002]

2. Description of the Related Art Conventionally, in a mobile communication network such as a portable telephone network and a PHS (Personal Handy Phone System), when a service area of a mobile communication service is to be newly established, one or more radio base stations for transmitting and receiving radio signals are required. And at least one mobile communication exchange for accommodating the radio base station and performing mobile communication processing specific to mobile communication, such as authentication processing for authenticating the validity of the mobile terminal. Accordingly, it is necessary to construct a new mobile communication network in a service area to be newly established.

Here, a call connection operation of a conventional mobile communication network including a mobile communication process executed by a mobile communication exchange will be described with reference to FIG. 13 and FIG. It will be described using FIG.

As shown in FIG. 13, when a call is originated from a mobile terminal, the mobile terminal first transmits a control signal called a call setup signal to the mobile communication exchange via the radio base station.

A control signal exchanged between a mobile terminal and a radio base station is a protocol (hereinafter, referred to as a "radio section protocol") predetermined as a protocol for a radio section of a mobile communication network. The control signal exchanged between the wireless base station and the mobile communication exchange is based on a protocol predetermined as a protocol for a wired section of the mobile communication network (hereinafter, “wired section protocol”). The wireless base station converts the call setup signal (call setup signal according to the wireless section protocol) received from the mobile terminal into a call setup signal according to the wired section protocol. After conversion, it is transmitted to the mobile communication exchange.

The mobile communication exchange analyzes a call setup signal received from a mobile terminal via a radio base station, and, based on the call setup signal, information necessary for call connection with an existing public communication network, and a call origination signal. The information necessary to authenticate the validity of the original mobile terminal is extracted. Specifically, such information is information such as a caller telephone number and a callee telephone number. Then, after extracting the information, the mobile communication exchange generates a control signal to be transmitted to the mobile terminal (here, it is a call setting acceptance signal) and transmits the generated call setting acceptance signal to the radio base station. Transmit to the mobile terminal via the station. At this time, the mobile communication exchange generates a call setting reception signal according to the wired section protocol, and the radio base station generates the call setting reception signal (the call setting reception signal according to the wired section protocol) received from the mobile communication exchange. After the protocol is converted into a call setting acceptance signal according to the wireless section protocol, the signal is transmitted to the mobile terminal.

Subsequently, the mobile communication exchange generates a random number for authentication, generates a control signal to be transmitted to the mobile terminal (here, an authentication request signal), and generates the generated authentication request signal. Is transmitted to the mobile terminal via the radio base station. The generated random number is set in the authentication request signal. At this time, the mobile communication exchange generates an authentication request signal according to the wired section protocol, and the radio base station converts the authentication request signal (authentication request signal according to the wired section protocol) received from the mobile communication exchange into the wireless section protocol. After the protocol conversion into an authentication request signal according to the above.

[0008] Further, the mobile communication exchange, based on the caller telephone number extracted from the call setting signal, stores information (for example, an authentication key) required for authentication processing in an internal storage device or an externally installed storage device. The authentication data is calculated using the authentication key extracted from the device and the random number generated earlier and transmitted to the mobile terminal.

On the other hand, the mobile terminal which has received the authentication request signal from the mobile communication exchange via the radio base station transmits an authentication key (an authentication key of the mobile terminal stored in the mobile communication exchange side) stored in an internal memory in advance. When the authentication data is calculated using the same key as the key) and the random number set in the authentication request signal, an authentication response signal in which the calculated authentication data is set is sent to the radio base station. To the mobile communication exchange via At this time, the wireless base station converts the authentication response signal (authentication response signal according to the wireless section protocol) received from the mobile terminal into an authentication response signal according to the wired section protocol, and then transmits the authentication response signal to the mobile communication exchange. I do.

[0010] The mobile communication exchange analyzes an authentication response signal received from the mobile terminal via the radio base station, and extracts authentication data calculated by the mobile terminal. Then, the mobile communication switch compares the authentication data calculated by the mobile terminal with the authentication data calculated by itself, and determines the validity of the mobile terminal of the transmission source.

When the authentication result is OK and the validity of the mobile terminal is confirmed, as shown in FIG. 14, the mobile communication exchange switches the control signal to be transmitted to the mobile terminal (here, the call signal Is generated, and the generated call signal is transmitted to the mobile terminal via the radio base station. At this time, the mobile communication exchange generates a paging signal according to the wired section protocol, and the radio base station uses the paging signal received from the mobile communication exchange (paging signal according to the wired section protocol) according to the wireless section protocol. The protocol is converted to a call signal and then transmitted to the mobile terminal.

When the mobile terminal receives a call signal from the mobile communication exchange via the radio base station, it transmits a response signal to the mobile communication exchange via the radio base station. At this time, the wireless base station converts the response signal (response signal according to the wireless section protocol) received from the mobile terminal into a response signal according to the wired section protocol, and then transmits the response signal to the mobile communication exchange.

The mobile communication switch analyzes a response signal received from the mobile terminal via the radio base station, and generates a control signal to be transmitted to the mobile terminal (here, a response confirmation signal). The generated response confirmation signal is transmitted to the mobile terminal via the radio base station. At this time, the mobile communication exchange generates a response acknowledgment signal according to the wired section protocol, and the radio base station generates a response acknowledgment signal (a response acknowledgment signal according to the wired section protocol) received from the mobile communication exchange.
Is converted into a response acknowledgment signal according to the wireless section protocol, and then transmitted to the mobile terminal.

As a result, the state between the mobile terminal and the mobile communication exchange is changed to a call state.

Thereafter, the mobile communication exchange generates and generates a control signal (here, a call setting signal) to be transmitted to the existing public communication network based on the information extracted from the call setting signal. A call setting signal is transmitted to the existing public communication network. The control signal exchanged with the existing public communication network follows a protocol (hereinafter, referred to as "inter-network protocol") predetermined as a protocol between the existing public communication network and the mobile communication network. Therefore, the mobile communication exchange generates a call setup signal according to the network protocol.

The existing public communication network which has received the call setting signal from the mobile communication exchange transmits a call setting acceptance signal to the mobile communication exchange.

The mobile communication exchange analyzes the call setting acceptance signal received from the existing public communication network, and a control signal to be transmitted to the existing public communication network (here, a call signal).
Is generated, and the generated call signal is transmitted to the existing public communication network. At this time, the mobile communication exchange generates a call signal in accordance with the inter-network protocol.

The existing public communication network which has received the call signal from the mobile communication exchange transmits a response signal to the mobile communication exchange.

The mobile communication exchange analyzes the response signal received from the existing public communication network, and generates and generates a control signal (here, a response confirmation signal) to be transmitted to the existing public communication network. A response confirmation signal is transmitted to the existing public communication network. At this time, the mobile communication exchange sends a response confirmation signal,
Generated according to the network protocol.

As a result, the state of communication between the existing public communication network and the mobile communication exchange is changed to a communication state, so that communication between the mobile terminal and the destination can be performed.

As described above, in the conventional mobile communication network, the radio base station performs protocol conversion between the mobile terminal and the mobile communication switch. In addition, the mobile communication exchange generates a control signal to be transmitted to the radio base station in accordance with a wired section protocol and transmits the control signal to the existing public communication network in the mobile communication processing executed to realize the call connection operation. Since a control signal to be generated is generated according to an inter-network protocol, as a result, protocol conversion between the wireless base station and the existing public communication network is performed.

As an example of the prior art relating to a mobile communication network, there is a mobile communication system described in Japanese Patent Application Laid-Open No. Hei 7-131842.

The mobile terminal 200 is connected to the radio base station 100
When the mobile station moves from the radio wave reach area a to the radio wave reach area of the radio base station 100b,
Since a detects that the radio wave level from the mobile terminal 200 has fallen below the threshold value, a transmits a handover request signal to the wireless base station device 100b via the individual line 800.

[0147] In the radio base station apparatus 100a,
The radio wave level from the mobile terminal 200 is monitored by the radio signal transmitting / receiving unit 102, and the handover request signal is generated by the CC 107 that detects that the radio wave level from the mobile terminal 200 has fallen below the threshold, and the individual line IF Transmitted by the unit 109.

The authentication process is performed.

When the authentication result is OK and the validity of the mobile terminal 200 is confirmed, the radio base station apparatus 100 notifies (transfers) the position information of the mobile terminal 200 to the management apparatus 901. In addition, the transfer of the position information
This is performed under the control of C107.

Thereafter, when a position information registration end signal is returned from management device 901, radio base station device 100
Transmits a location registration acceptance signal to the mobile terminal 200.

If the authentication result is NG, the radio base station apparatus 100 transmits a location registration acceptance rejection signal in which the reason for the facility rejection is set internally to the mobile terminal 200, and the management apparatus 901 Does not take any action. However, if the management device 901 also needs to collect authentication NG information, the NG information may be transferred.
