Data call terminating service system and method for dynamic IP of mobile communication terminal. One of known secure communication technologies in a wireless mobile communication system is a Data Encryption Standard DESwhich encrypts data using a private key. In accordance with an aspect of the present invention, there is provided a method for automatically entering into a secure communication mode in a wireless communication terminal, including the steps of: Device Manager First try updating all your drivers.
Provided are a method for automatically entering into a secure communication mode that can perform secured voice communication between a transmission terminal and a reception terminal without changing or pre-setting a conventional wireless mobile communication system by forming part of a voice signal as a token for attempting secured voice communication, and a computer-readable recording medium for recording a program that implements the method.
Exemplary embodiments in accordance with the present invention will now be described in detail with reference to the accompanying drawings.
Method and system for status of application storing by using mobile communication terminal.
Mobile communication terminal equipped with location-based short message service system, location-based message generation method and location-based message display method. A baseband circuit of the wireless communication unit and most circuits of the controller are integrated into a commercially available single chip. For example, in a data encryption standard exclusive-ORed DESX technology, master and session keys are used to perform secured voice communication.
In addition, the method carried out by a communication server includes the steps of: Method and system for terminating PPP session in dormant state of mobile communication terminal. Then, at step Sit determines whether token data for secured voice communication are transmitted from the transmission terminal. Method and apparatus for generating pseudo random sequence in broadband wireless communication system.
Here, at step Sthe voice decryption unit transmits the same acknowledge token data repeatedly a predetermined times.

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a method communicatiion entering into a secure communication mode from a normal communication mode by forming part of a voice signal communicated between a transmission terminal and a reception terminal as a token for attempting secured voice communication without changing the conventional establishment of a wireless mobile communication system, curiyel a computer-readable recording medium for recording a program that implements the method.
Users transfer music files, send photos, and surf the web much more frequently than before. Generally, the output data of the vocoder have various lengths, such as full, half, quarter and eighth rates.
The mobile communication terminal according to the present invention synchronizes the time when multimedia data is updated, for example, when the multimedia data is added, modified, or deleted, or the digest information of the multimedia data.
The multimedia processor outputs multimedia data outputted from the signal processor to the display This application claims the priority of Korean Patent Application No. Patents Assigned to Curitel Communications, Inc. Here, the voice encryption unit transmits the same token data communicafion a predetermined times for example, 20 ms-unit frames are transmitted repeatedly for 4.
The digest information synchronization unit - 3 compares the multimedia digest information stored in the first sub-memory vommunication the multimedia digest information of the second sub-memory - 2and retrieves digest information of multimedia data taken by the camera unit This process can be performed in various modes, and it should go through 16 communicstion of operations. A voice signal of a user which is inputted to the microphone of the transmission terminal goes into the vocoder and is outputted in the form of 20 ms-based voice packet data.
