Abstract

The invention discloses a mobile communication terminal device capable of realizing quick and continuous smooth switch during the roaming among data communication networks and an information exchanging method thereof. The mobile communication terminal device comprises a network access unit with a network access mechanism and a multi-address determination unit, wherein the multi-address determination unit is used for acquiring information by using a group of interfaces to exchange information with the network access unit; the information represents that a channel used in an existing communication session is interrupted; an upper layer of a network layer is notified before the interruption occurs actually; the group of interfaces comprises setting interfaces and triggering interfaces; the setting interfaces are used for sending signals to the network access unit by the multi-address determination unit, wherein the signals contain identifiers for identifying events notified by requiring the network access unit via the multi-address determination unit; and the triggering interfaces are used for sending signals to the multi-address determination unit by the network access unit, whereinthe signals contain identifiers for identifying the network access unit and are used for notifying event occurrences or future occurrences.
