Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal communication base station system, for example, a personal handy phone (Pe).
It is applicable to the rsonal Handy Phone system.

[0002]

2. Description of the Related Art In recent years, personal handy phones (PH
P) System research and development is underway. This is a simple mobile phone system, for example, which digitizes a cordless phone that is becoming popular in the home, and allows a child device to be taken outdoors to use public services like a mobile phone. Therefore, it is said to be the trump card for personalization of communication, "one per person", and its trend is drawing attention for its practical application and commercialization.

In the current relationship between a base unit and a handset of a cordless telephone, the base unit plays the role of a base station connected to the public network, and the handset plays the role of a mobile station. The idea of this PHP system is to install a large number of base stations outdoors so that no matter where you take them out, you can enter any one of the base station areas. The aim is to be able to use as a mobile phone.

In order to realize the services of the PHP system as described above, there has been a demand for a mechanism for realizing the services without newly installing dedicated equipment or dedicated lines.

As one example of the above-mentioned request, a technique disclosed in Japanese Patent Laid-Open No. 3-214823 "Personal Communication Base Station Configuration" has been proposed.

The gist of the invention of this document is "a base station in a digital public telephone as a base station in personal communication for directly calling a large number of unspecified subscriber terminals moving in an unspecified place and setting a communication path. It is configured to embed the station,
The public telephone has a function as a personal communication base station in addition to a call originating / receiving function as a telephone, and among the subscriber digital lines 2B + D from an exchange to the public telephone, a D channel for transmitting control information is connected to the public telephone. Even when the public telephone is shared by the base station and the public telephone is in use, the location of the personal communication terminal passing through the same station zone can be registered. ”

It is considered that the technique as described in this document can be realized to some extent by utilizing the existing public telephone and public telephone line.

[0008]

However, it goes without saying that according to the technique of the above-mentioned document, the base station function cannot be realized in a place where a public telephone is not installed. Therefore, if the service area of the base station function of the public telephone is widened, the installation interval of the public telephone can be widened, but in this case, it is necessary to relatively increase the transmission power of the base station and the mobile station. Therefore, the mobile station has a large power load, and it is difficult to reduce the size and weight.

Due to such difficulties, it is not appropriate to arrange public telephones having a base station function at too wide an installation interval.

Further, according to the above-mentioned document, it is described that the position of the subscriber wireless terminal can be registered through the D channel even during a call on the public telephone having the base station function. It is considered that the subscriber wireless terminal device cannot make a call while the public telephone having the base station function is busy.

Further, in the technique of the above-mentioned document, when making a call between the speaker of the public telephone and the subscriber wireless terminal, it is considered that the call is made after the line connection is made through the exchange. Therefore, for example, there is a problem that the above-mentioned call cannot be performed when the exchange has a failure.

Due to various problems as described above, PHP
There is a demand for a specific mechanism that makes the system easier and more practical.

The present invention has been made in view of the above problems, and an object of the present invention is to have a simple structure and to be easily compared with a conventional one, a communication device configured in an ISDN public network, and a mobile device. It is to provide a personal communication base station system capable of efficiently communicating with a terminal device, a wired terminal device, or the like, or between a mobile terminal device and a wired terminal device.

[0014]

In order to achieve the above object, the present invention is a base station function device in which a communication device and a mobile terminal device configured in an ISDN public network are connected to an ISDN public line. Through the above, a personal communication base station system capable of performing personal communication has been realized with the following characteristic configuration.

That is, the above base station functional device is provided with the following means. First, the basic interface accommodating means for accommodating the basic interface signals of the ISDN line for the mobile terminal device and the wired terminal device is provided.

Is output to the wired terminal device or an information channel signal from the wired terminal device is provided to the basic interface accommodating means by the second information channel.

The mobile terminal device and the wired terminal device are characterized in that the communication processing can be performed in parallel by using the base station function device.

In the above personal communication base station system, the base station function device is managed in any one of the ISDN public networks, and the communication device or the wired terminal device and the mobile terminal device which are configured in the ISDN public network. It is also preferable to configure a base station function control device that assists and controls the communication with the.

The above-mentioned basic interface signal is
For example, it means a basic interface signal of 2B channel + D channel.

As described above, the base station function device is ISD.
It can also be applied to a terminal adapter or a line terminating device that accommodates a basic interface of N lines.

[0023]

In the personal communication base station system of the present invention, the corresponding control means is a control channel (D channel).
From the information such as call control information and packet information, the correspondence of the mobile terminal device or the correspondence of the wired terminal device is determined. Then, based on this determination, mobile terminal device corresponding control information, wired terminal device corresponding control information, and the like are generated as necessary and given to the mobile terminal device corresponding means, the wired terminal device corresponding means, and the like.

That is, for example, when the call control information for the mobile terminal device is first given to the correspondence control means, the mobile terminal device correspondence control information is generated. Further, for example, when the call control information for the wired terminal device is first given to the correspondence control means, the wired terminal device corresponding control information is generated. Furthermore, assuming, for example, that the call control information from the mobile terminal device and the call control information from the wired terminal device are given to the corresponding control means at exactly the same time, in such a case, one of them is given priority. One of them can be put on hold.

And, the mobile terminal device corresponding control information is
For example, it is control information for enabling communication between the mobile terminal device and the base station function device and enabling a call through the information channel (B channel). Further, the wired terminal device compatible control information is, for example, control information for enabling communication between the wired terminal device and the base station function device and enabling a call through the B channel.

When the mobile terminal device corresponding control information is given, the mobile terminal device corresponding means performs a calling operation to the mobile terminal device and a transmission / reception operation for a call through the B channel. Further, the wired terminal device corresponding means, when given the wired terminal device corresponding control information, performs a calling operation to the wired terminal device and a transmission / reception operation for a call through the B channel.

From the above, the control channel is shared by the control of the mobile terminal device and the control of the wired terminal device, so that both controls are not started at the same time, but both calls can be performed at slightly different timings. And the mobile terminal device and the wired terminal device are connected to each other in parallel at almost the same time.
It is possible to talk with different communication devices configured in the SDN public network.

When the wired terminal device and the mobile terminal device communicate with each other, for example, by either call signal,
The response control means makes a determination for the line connection processing,
Necessary control information can be given to the mobile terminal device corresponding means or the wired terminal device corresponding means to start communication through the B channel.

A base station that manages the base station function device in any of the ISDN public networks and assists and controls the communication between the communication device or the wired terminal device configured in the ISDN public network and the mobile terminal device. By configuring the function control device, when a plurality of base station function devices are installed, it is naturally necessary to manage the mobile terminal device to which each base station function device belongs. Therefore, when such a mobile terminal device is managed and a mobile terminal device having a communication device or a wire terminal device of the ISDN public network is called, the managed information (position information etc.) is used to minimize the It becomes possible to establish a line connection to the base station function device with which the mobile terminal device is registered in time.
