Description

  The present invention relates to a radio base station apparatus, control method, control program, and communication system, and more particularly to a radio base station apparatus installed in a communication area where radio communication radio waves are weak, a control method thereof, a control program, and a communication system. .

In a mobile communication system, a base station apparatus connected to an exchange station apparatus through a dedicated line and a terminal apparatus existing within the communication area perform wireless communication.
However, even within the communication area of the base station device, in a place where radio waves are weak or shielded (hereinafter referred to as “weak radio wave area”) such as in a building or underground, the terminal device and the base station When wireless communication is not established between station devices and a terminal device exists in such a weak radio wave area, mobile communication with the terminal device is interrupted.

Conventionally, as a technology that enables mobile communication in the weak radio wave area as described above, a mobile communication system including a femtocell access point, which is a radio base station apparatus having an extremely small communication area, has been proposed. Yes. The femtocell access point is a very small wireless base station device having a communication range of about several tens of meters, and is connected to a mobile communication network via a broadband line that is a fixed communication network.
A femtocell access point installed in a weak radio wave area or the like performs wireless communication with a terminal device that cannot wirelessly communicate with a normal base station device, and realizes mobile communication by this terminal device.

  For example, in a mobile communication system of a so-called third generation (hereinafter referred to as “3G”) mobile phone that realizes packet communication including video communication and data communication as well as voice communication, it is within the communication area of the 3G base station. By installing a femtocell access point in the weak radio wave area, a 3G terminal device existing within the communication area of the femtocell access point can communicate with a normally installed 3G base station device. Despite being impossible, it is connected to the 3G communication network via the femtocell access point, and mobile communication by the 3G terminal device can be performed.

  On the other hand, in order to ensure communication quality or provide a stable communication service, the communication partner, such as a communication service provider, is a communication path type, for example, data communication via a broadband line or data communication via a narrowband line. It may be necessary to be able to distinguish whether it is. In a mobile communication system including a femtocell access point as described above, whether the communication service provider is mobile communication via a broadband line via the femtocell access point or a base station that is normally installed It is necessary to distinguish and recognize the type of communication path, whether it is mobile communication via a station device.

On the other hand, Patent Document 1 discloses a technique for adding header information including an address identifier unique to a base station to an upstream communication signal. Patent Document 2 does not allow a mobile phone to make a call. There is disclosed a technique for notifying a communication network of a unique identification code possessed by a micro base station capable of making a call even in a zone.
Patent Document 3 discloses a data transmission technique for performing packet communication by converting the content of user data in accordance with the transmission status of the communication so that the communication service can be received stably. .

Japanese Patent Application Laid-Open No. 2000-115829 JP 2006-261722 A JP 2005-328441 A

However, as disclosed in Patent Document 1, when a communication system is constructed by sequentially connecting a plurality of base stations to a shared communication line that connects a base station controller and a base station, This is intended to improve the line efficiency by flexibly changing the transmission rate assigned to each connected base station, and does not specify the type of communication path in mobile communication.
In addition, the technique disclosed in Patent Document 2 discloses a radio base station that is normally installed by notifying a communication network of an identification code unique to the micro radio base station when the micro radio base station is activated. The base station operates in the same way as in the above, but the communication partner of the mobile communication is the type of communication path, that is, whether the communication is via this microminiature base station, or is normally installed. It is not possible to specify whether the communication is via a wireless base station.
The technique disclosed in Patent Document 3 is a data transmission method that monitors the communication status, determines the optimum data size for the communication status, and converts the content content so as to match the optimum data size. The type of communication path with the terminal device is not specified.

Therefore, in the conventional technology as described above, whether the communication path with the terminal device is via a dedicated line via a base station device that is normally installed, or via a broadband line via a femtocell access point Since the communication partner such as a server device that provides the service cannot be recognized as to whether the communication is performed, there is a possibility that the communication quality in the mobile communication system and the stable provision of the communication service may be hindered.
In order to solve the above problems, the present invention provides a radio base station apparatus that allows a communication partner to recognize the type of a communication path with a terminal apparatus without changing the specifications of the communication infrastructure and the terminal apparatus, and its control It aims to provide a method.

[Connection authentication operation]
The radio signal transmission / reception unit 210 receives the radio band signal transmitted from the terminal device A and outputs communication data from the radio band signal, but receives the communication data received from the terminal device A for the first time, that is, the terminal authentication request. When it does (S201), the terminal authentication part 240 performs connection authentication of the terminal device A (S202 to S204).

  When the identification information included in the terminal authentication request received by the wireless signal transmission / reception unit 210 does not match the identification information registered in the connection-permitted terminal information (“No” in S202), the terminal authentication unit 240 Connection with the terminal device A that is the transmission source of the communication request is not permitted. Therefore, the radio signal transmitting / receiving unit 210 ends the reception operation of the radio band signal transmitted by the terminal device A (S203).

  On the other hand, when the received identification information matches the identification information registered in the connection-permitted terminal information (“YES” in S102), the terminal authentication unit 240 connects to the terminal device A that is the transmission source of this communication request. And an authentication response is transmitted to the terminal device A (S204). Thereafter, the femtocell access point 20 starts wireless communication with the terminal device A that has received the authentication response.

[User plane data conversion operation]
Next, the radio signal transmission / reception unit 210 receives the radio band signal transmitted from the terminal device A, and outputs communication data from the radio band signal (S205).
The operation selection unit 222 selects an operation to be executed based on the content of the communication request included in the communication data output from the wireless signal transmission / reception unit 210, that is, the request content of the user plane data of this communication data (S206).

The data conversion unit 220 outputs communication data including information indicating the type of communication path converted by the conversion rule application unit 224 to the network side transmission / reception unit 230 (S209).
The network side transmission / reception unit 230 transmits the communication data output from the data conversion unit 220 to the broadband line B-1 to transmit to the server device E as communication data in packet communication (S210). Therefore, the communication partner receiving this communication data can determine the type of the communication path based on the contents of the user plane data of the communication data.

[Specific example of user plane data conversion]
Here, conversion of user plane data in accordance with the conversion rule will be described with reference to an example of the conversion rule shown in FIG. In this example, “44001009012345678” represents the identification information of the terminal device A.

If the message “User-Agent: *” is included in the content of the user plane data of the communication data transmitted from the terminal device A having “44001009012345678”, the conversion rule search unit 223 stores the message in the conversion rule storage unit 221. A conversion rule corresponding to the content of the user plane data is searched from the conversion rules that have been set, and the existence of the corresponding conversion rule is confirmed. The conversion rule application unit 224 converts a part of the user plane data into “User-Agent: femto / mobile-phone” in accordance with the conversion rule confirmed by the conversion rule search unit 223.

[Conversion rule update]
Next, the update operation of the conversion rule stored in the conversion rule storage unit 221 will be described.
When the content of the communication request for the communication data transmitted from the terminal device A is a conversion rule update request, the operation selection unit 222 selects a corresponding conversion rule from the conversion rules stored in the conversion rule storage unit 221. The operation by the conversion rule update unit 225 to be updated is selected (“rule update request” in S206).

  At this time, when the conversion rule update operation is selected by the operation selection unit 222, the conversion rule search unit 223 performs conversion corresponding to the conversion rule update request received from the conversion rule stored in the conversion rule storage unit 221. A rule is searched (S211). Here, the conversion rule corresponding to the update request is the conversion rule stored in association with the identification information of the terminal device A that is the transmission source of the conversion rule update request, or the conversion included in the received communication data This is a conversion rule searched by the conversion rule search unit 223 based on the updated contents of the rule.

As a result of the conversion rule search performed by the conversion rule search unit 223, the conversion rule update unit 225 executes a corresponding conversion rule update process (S212).
