Abstract: An Internet education system and a method thereof are provided to enable a learner to check pronunciation instantly by listening to the pronunciation of currently learning foreign language voice, which is instantly recorded and played. A learning database(110) stores foreign language learning contents, the foreign language voices and the predicted answers corresponding to respective foreign language contents. A voice recognizer(120) recognizes the foreign language voice of the learner received from a learner computer(200) through the Internet. A voice processor(130) converts the recognized foreign language voice of the learner into a text. A controller(140) provides the learner computer with the foreign language voice corresponding to the foreign language contents selected by the learner and a speaking request, and compares the foreign language voice of the learner converted into the text with the predicted answers corresponding to the foreign language voice. If the foreign language voice of the learner is the required answer, the controller provides a foreign language voice file of the learner to the learner computer and outputs a playback command.

Title: Method for managing handoff proceduer of a mobile node in a mobile communication supporting proxy mobile internet protocol

IPC: H04B7/26
Filed: 2006-09-08
Abstract: A method and a system for managing the handoff of a mobile node in a mobile communication system which supports PMIP(Proxy Mobile Internet Protocol) are provided to prevent a wrong operation in the process of transmitting a BU(Binding Update) or RRQ(Registration Request) message to a HA(Home Agent) in case a mobile node uses CMIP(Client Mobile Internet Protocol). A T-PDSN(Target Packet Data Service Node)(105) transmits a request message for the handoff of a mobile node, which moves to the area of a target access network, to an S-PDSN(Serving PDSN)(103). The T-PDSN transmits a proxy BU message to a HA and executes registration for the handoff of the mobile node. Waiting for a response for the proxy BU message, the T-PDSN judges whether or not a CMIP BU message is received from the mobile node. In case the CMIP BU message is received from the mobile node, the T-PDSN filters the received CMIP BU message.
