摘要： Disclosed herein is a mobile communication terminal and handover method therefor, which enable handover of a mobile communication terminal that is using a packet data service or is in a dormant state in a mobile communication network in which asynchronous and synchronous networks coexist. In the handover method, if a channel is assigned between a mobile communication terminal and a synchronous mobile communication system in response to a request from an asynchronous mobile communication system as a mobile communication terminal using packet data service in the asynchronous mobile communication system moves into an area of the synchronous mobile communication system, call setup is performed. A node B of the asynchronous communication releases a connection to the mobile communication system and assigns a new mobile IP to the mobile communication terminal, thus providing continuous packet data service to the mobile communication terminal.

摘要： In the present invention, as a mobile communication terminal, which is using service in the area of an asynchronous mobile communication system, detects signals from a synchronous mobile communication system, the mobile communication terminal repeatedly performs a process of examining whether, in a predetermined time, signals from the asynchronous mobile communication system have been detected a designated number of times, and measuring the intensity of the signals. When the number of times that the intensity of signals from the asynchronous mobile communication system is smaller than a designated number of times, or no signals from the asynchronous mobile communication system are detected, within the predetermined time, it is determined whether to perform handover of the mobile communication terminal.

摘要： Disclosed herein is a handover method for a mobile communication terminal in a mobile communication network in which an asynchronous network and a synchronous network coexist. In the present invention, as a mobile communication terminal, which is making a call through an asynchronous mobile communication system, moves into the area of a synchronous mobile communication system, and thus a handover event occurs, the establishment of a call with a synchronous mobile communication system is performed by the automatic call termination or origination of the mobile communication terminal while a connection between the asynchronous modem unit of the mobile communication terminal and the asynchronous mobile communication system is maintained, and then the connection with the asynchronous mobile communication system is released. Accordingly, a call interruption can be prevented at the time of handover between heterogeneous networks.

摘要： The present invention relates to a handover method for a dual band/dual mode mobile communication terminal between a synchronous mobile communication network and an asynchronous mobile communication network. The method includes the first step of the main processor setting an initial mobile communication network connection to the asynchronous mobile communication network and connecting to the asynchronous mobile communication network when power is applied; the second step of activating the synchronous RF device and setting up a connection to the synchronous mobile communication network when the intensity of a signal from the asynchronous mobile communication network is equal to or lower than a first predetermined reference value; the third step of determining whether the intensity of a signal from the asynchronous mobile communication network is equal to or lower than a second predetermined reference value previously set for the handover; the fourth step of activating the connection to the synchronous mobile communication network set up at the second step if the intensity of the signal from the asynchronous mobile communication network is determined to be equal to or lower than the second predetermined reference value at the third step; and the fifth step of releasing the connection to the asynchronous mobile communication network.

摘要： Disclosed herein is a mobile communication terminal and handover method therefor. In the mobile communication system, a Gateway GPRS Support Node (GGSN) of the asynchronous network is connected to a Packet Data Service Node (PDSN) of the synchronous network. Accordingly, as a mobile communication terminal, using packet data service in the asynchronous mobile communication system, moves into an area of a synchronous mobile communication system, the synchronous mobile communication system sets control signals and traffic to transmit packet data in response to a request from the asynchronous mobile communication system. Further, if forward and reverse channels are assigned between the mobile communication terminal and the synchronous mobile communication system, call setup is performed to provide the packet data service, and then a node B of the asynchronous mobile communication system releases the connection to the mobile communication terminal.
