Abstract: A roaming service method in a mobile broadcasting system and a system thereof are provided. A terminal receives a service guide from a corresponding visited service provider (Visited SP) when the terminal moves to a roaming area. The terminal transmits a roaming request message for requesting a purchase item allowable for individual services to a home service provider (Home SP) based on the received service guide. Upon receipt of the roaming request message, the Home SP negotiates roaming availability and allowable scope for each individual service with the Visited SP where the terminal is located, based on the roaming request message. The Home SP transmits the roaming availability and allowable scope for the individual service, negotiated with the Visited SP, to the terminal.

Abstract: A method and apparatus for performing handover on a voice call between a packet network system and a circuit network system is provided. Considering a communication environment where a UE cannot simultaneously use radio resources of both the next generation mobile communication system (LTE) and the legacy mobile communication system (e.g., GSM/WCDMA), the present invention proposes an SCSE for performing signal translation between the packet switched network and the circuit switched network and anchoring a voice call in the application level, and supports a continuous voice call using the SCSE.

Abstract: An apparatus for and method of estimating a one-way delay time between two hosts and an apparatus and method of clock synchronization using the same. The two hosts are connected to a network and communicate a predetermined packet; k-th, (k+1)-th, and (k+2)-th transmission times are measured at the first host, and k-th, and (k+1)-th transmission times are measured at the second host; a time difference of the m-th transmission time is measured at the first and second host, where m is k or k+1, and by using the measured transmission times, an m-th one-way delay time is calculated. If the time difference is identical to the calculated one-way delay time, a value equal to or less than the calculated one-way delay time is determined as the estimated one-way delay time. Accordingly, the estimation error of a one-way delay time is reduced for both symmetrically and asymmetrically connected hosts.

Abstract: A terminal apparatus is provided for receiving a broadcast service from a broadcasting system. A receiver receives a notification message from the broadcasting system. A message parser parses the notification message received by the receiver according to a certain format. A controller determines whether the received notification message is a notification message to be used by a user or a notification message to be used by the terminal based on content of the notification message parsed by the message parser, and performs an operation according to the determination result.

Abstract: Provided is a handover method, in which a call manager of a network having a Circuit Switching (CS) network, a Long Term Evolution (LTE) network, and an Internet Protocol Multimedia Subsystem (IMS) network, provides handover, from the LTE network to the CS network, to a terminal that uses one radio channel. The handover method includes upon receiving a request for handover from the terminal via a node of the LTE network, establishing a line to a Mobile Switching Center (MSC) of the CS network; sending, to the call manager, a request for a change in a session to another party's terminal in communication with the terminal, to establish an Internet Protocol (IP) bearer between the call manager and the other party's terminal; and sending a handover command to the terminal during the establishment of an IP bearer, to establish a radio channel to the base station of the CS network.
