JPS6382150A - Remote station control system for adding new service to existing communication network - Google Patents

Abstract

PURPOSE:To economically add a new service function by providing a 2nd exchange station controlling a new service to an existing exchange station additionally and providing one or over of remote stations controlled by the 2nd exchange station so as to connect the existing exchange station and the 2nd exchange station. CONSTITUTION:Remote stations a-d and a new exchange station Y having a new service function and having a function controlling the remote stations a-d are provided corresponding to existing exchange stations A-D and X. Then a subscriber NEW desiring a new service is accommodated in the remote stations to offer the new service to the subscriber under the control of the new station Y. The addition of new service is attained independently of the existing exchange stations A-D and X and the scale of station is decided by the number of subscribers desiring new service.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a remote station control method when adding a certain type of new service to an existing communication network, and particularly relates to a remote station control method for adding a certain type of new service to an existing communication network. A new station was installed for the purpose of introducing
This invention relates to a remote station control method in which this station controls a remote station that has a function for adding a new service χ.

(Prior Art) Conventionally, when a new service is to be added to a completed communication network, the entire communication network has been improved as necessary.

(Problems to be Solved by the Invention) In the conventional method of completely improving the entire communication network as described above, the cost associated with the improvement is immeasurable, and since the communication network in service is being remodeled, great care must be taken when remodeling. The drawbacks were that caution was required and modifications that would result in interruption of service were not possible.

Furthermore, even if only some subscribers desire the new service, it is necessary to remodel all stations, and in this case the economic loss becomes even more significant.

In general, communication networks are composed of various types of conversion stations, and some old exchange stations have the disadvantage that they cannot be modified to introduce new services.

An object of the present invention is to provide a remote station that can economically and easily add a remote station with new service functions without making any improvements to the existing exchange when adding new service functions to an existing exchange. The objective is to provide a station control system.

(Means for Solving the Problems) In order to achieve the above object, the remote station control system according to the present invention provides an existing exchange with a second exchange that controls the new service, and One or more remote stations controlled by the station are provided.

The switching center is configured to connect the existing switching center and the second switching center.

(Actual flow side) Next, the present invention will be explained with reference to the drawings.

The figure is a schematic diagram showing an embodiment of a remote station control method when adding a new service to an existing communication network according to the present invention.

Corresponding to existing exchanges A, B, O, D and X, remote stations a, b, c, d and new service functions are provided, and remote stations al b e Cjd? A new exchange Y with the ability to control? Equip. Subscribers NEWi who wish to receive the new service are accommodated in these remote stations, and the new service is provided to the subscribers under the control of the new station Y.

Therefore, it is possible to add new services regardless of the conventional exchanges A, B, O, D, and X, and remote stations a,
The scales of b, c, and d can be determined depending on the number of subscribers who desire the new service.

(Effects of the Invention) As explained above, the present invention provides a new exchange having a new service function and a remote station control function, and uses this to control remote stations accommodating subscribers who wish to receive new services. This has the effect of economically adding new service functions by determining the same scale of remote stations according to the number of subscribers who wish to receive the new service without modifying the communication network.

Further, even if the conventional switching center is an old type and cannot be modified to add new services, the nine objectives can be achieved by installing a remote station.

It is a schematic diagram showing a flow side.
