Abstract
A wired telephone which is equipped with a universal subscriber identification module (USIM) card, reads subscriber identification information from the USIM card when call origination is performed, and transmits a call setup request message including the subscriber identification information; When the call setup request message is received from the fixed telephone, it is determined whether the caller is a mobile communication subscriber by using the subscriber identification information included in the call setup request message. If the caller is a mobile communication subscriber, And a wired exchange for performing call processing according to a call setup request message if the subscriber is available, thereby constituting a communication system for providing a wired telephone service to the mobile communication subscriber. Accordingly, the mobile communication subscriber can use the wired telephone service using the USIM card even when the subscriber does not subscribe to the wired telephone service.
Mobile communication subscriber, fixed telephone service
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a communication system for providing a fixed line telephone service to a mobile communication subscriber, and more particularly, to a system and method for allowing a mobile communication subscriber to use a fixed line telephone service using a USIM card, To a wired telephone.
Currently, WCDMA mobile communication services are being provided to users. WCDMA (Wideband Code Division Multiple Access) mobile communication service refers to 3G mobile communication service that provides high quality video call and high speed data service based on WCDMA system.
A Universal Subscriber Identification Module (USIM) card, which is basically installed in a mobile communication terminal to which the WCDMA system is applied, is an essential component responsible for subscriber authentication in a WCDMA mobile communication service. The USIM card includes an International Mobile Subscriber Identity (IMEI), an electronic serial number (ESN), which is a unique number of a mobile communication terminal, a communication service provider, a user password, roaming information, user related information (personal telephone number, phonebook, Key), service information of a communication provider and a content provider, and the like.
Until recently, these USIM cards had a USIM lock. The USIM lock prevents the use of the WCDMA mobile communication service by not passing the information stored in the USIM card to the terminal when the USIM card is not installed in the predetermined terminal. Recently, the USIM lock is released and the subscriber can use the USIM card in any terminal to use the WCDMA mobile communication service.
Accordingly, the user can use the USIM card to use the WCDMA mobile communication service through any wireless terminal, but can not use the wired telephone service. Conventionally, a communication system for a one-phone service has been proposed in which a mobile communication service and a wired telephone service can all be utilized through one wireless terminal.
1 is a diagram illustrating a communication system for a conventional one-phone service.
Referring to FIG. 1, the one-
The one-
The outgoing call is transmitted to a wired terminal (not shown) or the
However, the user must be subscribed not only to the mobile communication network service but also to the wired telephone service, and the access point for the one-phone service must be provided. Since this access point terminal is very expensive, there is a disadvantage in that it takes a lot of cost for the user to use the one-phone service.
Therefore, if the user can use the landline telephone service by using the USIM card, the user can use the landline telephone service as well as the mobile communication service by using one USIM card.
An object of the present invention is to provide a method and a communication system for allowing a user to use a wired telephone service as well as a mobile communication service using a USIM card.
According to an aspect of the present invention, there is provided a communication system including a universal subscriber identification module (USIM) card, the subscriber identification information being read from the USIM card when call origination is performed, The mobile communication terminal of claim 1, wherein the call setup request message includes a call setup request message including identification information, and a call setup request message, the call setup request message including a subscriber identification information included in the call setup request message, And a wired exchange for performing call processing according to a call setup request message when the caller is a mobile communication subscriber and the mobile communication subscriber is a subscriber who can use a wired telephone service.
Here, when the communication system receives the information of the mobile communication subscriber from the wired exchange, the mobile communication subscriber requests authentication of the mobile communication subscriber to the mobile switching center of the mobile communication network, and based on the authentication result, And a service server for determining whether the subscriber is a subscriber who can use the service and transmitting the information of the subscriber to the wired exchange.
Here, the wired exchange may transmit the charging information according to the call processing to the service server after performing the call processing.
Here, the service server may include a database for storing information on mobile communication subscribers who can use the wired telephone service and the billing information.
Here, if the mobile communication subscriber is provided with a specific service that allows the mobile communication subscriber to use the fixed-line telephone service, the service server determines whether the mobile communication subscriber has registered the specific service so that the mobile communication subscriber uses the fixed- It is possible to determine whether the subscriber is a subscriber.
According to another aspect of the present invention, there is provided a method of providing a landline telephone service to a subscriber of a mobile communication terminal, the method comprising the steps of: providing a wired telephone service to which a universal subscriber identification module (USIM) In a communication system including a telephone, a wired exchange, and a service server, when the call is performed in the state that the USIM card is installed in the wired telephone, the wired telephone reads the subscriber identification information from the USIM card, When the wired exchange receives the call setup request message from the wired telephone, determining whether the caller is a mobile communication subscriber using the subscriber identification information included in the call setup request message; If the wired exchange is the mobile communication subscriber of the originator, And performing call processing according to the call setup request message if the communication subscriber is a subscriber who can use the wire telephone service.
Herein, the method of providing a wireline telephone service to the mobile communication subscriber includes the steps of: requesting authentication of the mobile communication subscriber to the mobile switching center of the mobile communication network when the service server receives the information of the mobile communication subscriber from the wired exchange; Determining whether the mobile communication subscriber is a subscriber who can use the wired telephone service based on a result of the authentication and transmitting the information of the mobile communication subscriber to the wired exchange; have.
Here, the method for providing a wire telephone service to the mobile communication subscriber may further include transmitting billing information corresponding to the call processing to the service server after the wired exchange performs the call processing.
Here, the method of providing a wireline telephone service to the mobile communication subscriber may include: when a specific service is provided so that the mobile communication subscriber can use the wireline telephone service, the service server registers the mobile communication subscriber to the specific service Determining whether the mobile communication subscriber is a subscriber who can use the landline telephone service by judging whether the subscriber is a subscriber or not.
Using the communication system and method for providing a wired telephone service to the mobile communication subscriber according to the present invention, the mobile communication subscriber can use the wired telephone service using the USIM card even when the subscriber does not subscribe to the wired telephone service have.
