  • Publication number: 20050079882
    Abstract: A method and system for providing a short message service (SMS) in a network interworking between a wireless public network and a wired/wireless private network can provide the short message service through the private network directly when a user wishes to transmit the short message service through the private network in the interworking network. The method includes a first step of setting up an identifier determining through which of the public and private networks to transmit the short message service, and a second step of retrieving the transmitted identifier of a terminal and transmitting the short message service to a corresponding network according to retrieved information. Since it is possible to selectively transmit SMS data using the public network or the private network in the interworking network, and the SMS data can be transmitted to the private network by changing the system without changing the terminal of each user, there occurs no additional expense.

  • Publication number: 20040196810
    Abstract: A complex wireless service apparatus using wired and wireless communication systems and a method thereof includes, when a call of the complex wireless terminal is not reachable, a call forwarding is automatically tried through another network by making a location of a service user to be registered automatically using the complex wireless terminal, and the service user can make a speech without any disconnection using a hand off between networks for the complex wireless terminal when the user moves from one network to another network during making a call. A home location register stores a database of a mobile communication phone number for the complex wireless terminal, whether an extension is located inside or outside, a public phone number, and a wireless terminal unique number.

  • Publication number: 20040185880
    Abstract: A system for providing a private mobile communication service separately from a public mobile communication network and method of processing a call using the same. The system includes a mobile station for establishing a radio communication channel with a private BTS (pBTS) when it moves from a public-only cell to a public/private common cell; and establishes a traffic channel with the pBTS if an identifier is added to a dialed number, and establishes a traffic channel with a public BTS if the identifier is not added. A private communication service apparatus determines, if a traffic channel request is received from the mobile station, whether the mobile station is a subscriber to the private mobile communication service, establishing a radio communication channel if the mobile station is a subscriber, and establishing a traffic channel over a private network and a public switched telephone network.

  • Publication number: 20040048614
    Abstract: A private mobile communication system is for providing a public network busy state information of a mobile communication terminal. The private mobile communication system for informing a call origination mobile communication terminal of a public network busy state of a mobile communication terminal registered in a mobile communication system includes an HLR (Home Location Register) having a parameter indicating a public network busy state with respect to each mobile communication terminal registered in a private mobile communication system, and a message routing module for setting up a public network busy state of the mobile communication terminal in the case where the mobile communication terminal performs a call origination or a call reception over a public mobile communication network within a private mobile communication network.

  • Publication number: 20030100342
    Abstract: A public land mobile network (PLMN)/private wireless network-integrated service network and a system for the service network. The service network according to the present invention can interwork with any PLMN with no dependence on an upper system. In the present invention, there is no need for a public BSC and a separate private BSC. The novel BSC handles both public and private data and voice calls placed from or placed to a mobile station or terminal. The novel BSC enables a wireless phone or terminal to place and receive calls using either the public communications network or the private communications network. Thus, the need for a redundant private BSC is eliminated while providing the diversity of services to mobile stations.
