Description

COMMUNICATION SERVICE SYSTEM AND METHOD USING A SINGLE TELEPHONE NUMBER AND E- MAIL ADDRESS
BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a communication service system and a method of the same, and in particular to a communication service system using a single telephone number and electronic main address and a method of the same which are capable of integrally managing a voice and data communication by providing all directors and staff of a certain company which uses an exclusive communication network for a voice and data communication in the interiors of a plurality of local and abroad business sites for thereby performing a voice and data communication with a local and abroad business site through a single telephone number and electronic mail address by a corresponding director as well as with external telephone and computer users.
2. Description of the Background Art
Recently, a service which is implemented as another service in the same field such as voice re-selling service, internet telephone, and call-back service is called as a privileged communication service as a communication market is opened based on a basic communication negotiation of the WTO(World Trade Organisation).
The privileged communication service is a kind of an information communication system in which various good quality information communication services are provided at economical and reasonable prices to a customer compared to a conventional key communication company by buying and renting a communication facility or a service from a conventional key communication company, providing an additional service to a customer and selectively using an additional service through a network. In a view of a communication business company expedites and reinforce a competitiveness based on a development of a market. In addition, in a view of customer, it is possible to decrease a service charge and increase the quality of service. In a view of the nation, the local information communication network is developed. Recently, the companies do not limit their business ranges to a certain region or a certain nation but expand their business ranges to many countries. As the business is expanded, the use of the communication instrument such as a telephone and fax machine is increased, so that the costs related to the communication are increased.
Many companies try to save a local and abroad communication cost used by the directors and staff and install an exclusive communication network for an efficient voice and data communication between local and abroad business sites. However, in almost companies which install the exclusive communication network, a communication network use efficiency is not high(about 150%), and the costs required for operating the exclusive communication network are fixed. In the case that the exclusive communication network is expanded, a non-efficiency is more increased, and a communication cost and operational cost are sharply increased. In addition, in order to implement a more stable service compared to when the exclusive communication network is used, a compression equipment, management equipment, etc. should be continuously upgraded. In addition, the number of staff who perform a maintenance of the exclusive communication network should be increased, so that a lot cost for a communication infrastructure is needed. In addition, there is a limit for decreasing the cost for a communication of company staff and directors.
In addition, since the protocols between the voice communication and the data communication are different, it is impossible to combine and operate together the voice and data communications based on an exclusive communication network in a view of a corresponding company. In the case of the electronic mail, since the resource of the electronic main address is lack, and the domains by the nation are different, there is a limit for using the electronic mails through the integrated domains by all staff and directors. In addition, it is impossible to efficiently use the data communication due to the lack of an expert in a data security and international authentication. When a staff or director of a corresponding company is transferred , since the telephone number or electronic mail address used by a transferring staff or director must be changed, the cost is increased. In addition, in the case of a staff or director working in a cooperative section such as a sale or purchase section, when the telephone number or electronic main address are changed, it is needed to inform the changed information to each customer for thereby causing much inconvenience.

After the single telephone number and e-mail address provided to all staff and directors in the Step S1-5 are stored in the database form, the privileged communication service provider periodically receives a certain variation(new entrance, and retire of staff) of staff and directors from a corresponding company and updates the single telephone number and e-mail address. In a Step S2, the business site communication centre 20 is built in each business site by performing an exclusive communication network with respect to a certain company through the Step S1 , and then a single telephone number and e-mail address are provided to all staff and directors of a corresponding company. The privileged communication service provider installs more than one metro communication centre 30 capable of integrally managing a plurality of business site communication centres 20 installed in each business site by the nation of a certain company which made a contract of the exclusive communication contract.
In a Step S2-1 , the privileged communication service provider installs more than one metro communication centre 30 by the nation for integrally managing a plurality of business site communication centres 20 installed in the local and abroad business sites of a certain company which made a communication network contract. In a Step S2-2, an exclusive line is installed between the business site communication centres 20 by the nation and the metro communication centre 30 which integrally manage the same.
In a Step S2-3, the metro communication centre 30 installed in each nation is connected with the local and international network communication network 10 using a communication line installed by each nation communication service provider and international telephone line communication service provider which made a contract based on the use of the communication line.
In a Step S3, after the business site communication centre 20 is installed in each business site in the local and abroad regions with respect to a certain company through the Steps S1 and S2, and more than one metro communication centre 30 capable of integrally managing the business site communication centres 20 by the nation are installed, the privileged communication service provider controls a voice and data communication with the internal or external terminals 40 and 50 by the staff and directors of each business site communication centre 20 and a voice and data communication with the staff and directors of a certain company by the users of the external terminal 50 of each nation. In a Step S3-1 , the business site communication centre 20 installed in each business site in the side of the privileged communication service provider inputs a telephone number for requesting a voice and data communication with the other staff or director of the company or a user of the external terminal 50 using the internal terminal 40 such as a telephone or a computer by a staff or director of a corresponding business site communication centre 20 or judges whether an e-mail is made.
In a Step S3-2, when a certain staff or director inputs a telephone number or forms an e-mail, a corresponding business site communication centre 20 judges whether a telephone number ore-mail address inputted by a certain staff or director us a telephone number ore-mail address provided to a corresponding company or a telephone number of e-mail address of the external terminal 50.
In a Step S3-3, as a result of the judgement, in the case of the telephone number or e- mail address provided to a corresponding company, it is judged whether the telephone number or e-mail address inputted by a certain staff or director is a telephone number or e-mail address of the business site communication centre 20 of the same business site communication centre 20 or the same metro communication centre 30.
In a Step S3-4, as a result of the judgement, in the case of the telephone number or e- mail address of the other business site communication centre 20 of the same business site communication centre 20 or the same metro communication centre 30, the privileged communication service provider performs a voice and data communication with a corresponding staff or director by converting into an internal office telephone.
In a Step S3-5, as a result of the judgement of the Step S3-3, in the case that it is not the telephone number of e-mail address of the other business site communication centre 20 of the same business site communication centre 20 or the same metro communication centre 30, the privileged communication service provider outputs a voice or data communication request signal to the business site communication centre 20 of a corresponding staff and director through the metro communication centre 30 and the local and abroad international network communication network 10.
In a Step S3-6, as a result of the judgement of the Step S3-2, in the case that the telephone number or e-mail address inputted by a certain staff or director is not the telephone number or e-mail address provided to a corresponding company, the privileged communication service provider outputs a voice or data communication request signal of a certain staff or director to the user of the external terminal 50 through the metro communication centre 30 and the local and international network communication network 10 for thereby implementing a voice and data communication.
As a result of the judgement of the Step S3-1 , in a Step S3-7, if a staff or director of a certain company inputs a telephone number for a voice or data communication with the other staff or director of the company or a user of the external terminal 50 or does not form an e-mail, the privileged communication service provider judges whether the users of the external terminal 50 inputted a telephone number or e-mail address through the local and international network communication network 10 into the metro communication centre 30 installed in a corresponding nation. In a Step S3-8, when a telephone number or e-mail address are inputted by the user of the external terminal 50 for performing a voice or data communication with a certain staff or director, the metro communication centre 30 judges whether the telephone number or e-mail address inputted by the user of the external terminal 50 is the telephone number or e-mail address of the business site communication centres 20 connected with the metro communication centre 30.
In a Step S3-9, as a result of the judgement, in the case of the telephone number or e- mail address of the business site communication centres 20 connected with the metro communication centre 30, the privileged communication service provider implements a voice or data communication with a corresponding staff or director based on the telephone number or e-mail address inputted by the user of the external terminal 50.
In a Step S3-10, as a result of the judgement of the Step S3-8, in the case that the telephone number or e-mail address inputted by the user of the external terminal 50 is not the telephone ore-mail address of the business site communication centres 20 connected with the metro communication centre 30, the privileged communication service provider outputs a voice or data communication request signal to the business site communication centre 20 of a corresponding staff or director through the local and international network communication network 10 based on the information concerning the current local and abroad business site which is previously inputted by a corresponding staff or director without a user's additional operation of the external terminal 50.
In a Step 4, finally, after the voice and data communication with the users of the internal or external terminal 40 and 50 are performed by the staff and directors of each business site communication centre through the Step S3, and the voice and data communication are performed with the staff and directors of a certain company by the users of the internal or external terminals 40 and 50, the privileged communication service provider computes the local and abroad telephone rates and the costs related to the data communication maintenance used by a certain company based on the voice and data communication request by the staff or directors of the company and the users of the external terminal 50 and request the rates to a corresponding company, and a certain amount of the money is paid to each nation communication service provider and an international telephone network communication service provider for the use of the communication line.
In detail, in a Step S4-2, the privileged communication service provider computes the communication rates of a certain company based on the use of the local and international telephone communication performed by a voice and data communication requests of the staff and directors of the company and the users of the external terminal 50, and in a Step S4-2, computes the cost based on the data communication maintenance used by a certain company. In a Step S4-3, the privileged communication service provider judges whether the money request period(for example, one month) of the local and international telephone communication rates and data communication maintenance cost of the company which made a contract of the exclusive communication network is reached. As a result of the judgement, in a Step S4-4, the local and international rates and the data communication maintenance cost are requested to a corresponding company through the Steps S4-1 and S4-2.
In a Step S4-5, the privileged communication service provider which received the local and international communication rates and the data communication maintenance cost from a certain company pays a part of the money paid by the company to the communication service provider and the international telephone network communication service provider by the nation as the money for the use of the communication line.
