摘要： There is provided an optical information detecting method. The method includes: detecting an image of a source data page coded with balanced codewords by the use of 1:N (where N is greater than 1) excessive detection pixels; determining a distribution pattern of valid detection pixels and invalid detection pixels to be corrected in the detected image by the use of a light intensity distribution of the detected image; and dividing the detected image into balanced codeword detecting areas corresponding to the balanced codewords and sampling data of the balanced codeword detecting areas by the use of the determined distribution pattern and an optical distribution characteristic of the balanced codewords. Accordingly, it is possible to efficiently detect optical information by the use of a 1:N over-sampling method. Specifically, the distribution pattern of valid detection pixels and invalid detection pixels in the detected image of a data page can be properly used to sample a balanced code.

摘要： Provided is a method, apparatus and system for assigning an IP address in a communication system based on a Media Independent Handover (MIH). In the method, information about a neighbor network is obtained through an MIH service. In the event of a handover to a heterogeneous network, one or more New Care of Addresses (NCoAs) are generated using the information about the neighbor network. The generated NCoA is transmitted to a candidate network through the MIH service. A Duplicate Address Detection (DAD) operation is performed on the NCoA.

摘要： Provided is a method and system for supporting IMS VCC based on an MIH. In a method of supporting a multimedia service for an MIH-based VCC, neighbor network information is obtained from an MIH server periodically or according to an event trigger and scanning the neighbor network. The capacity of at least one more candidate networks is detected from the scanning results to prepare a handover. A target network is determined among the candidate networks to reserve resources and a handover command event is generated to perform a domain transfer. The handover is completed after the performing of the domain transfer.

摘要： Vertical handover apparatus and method in a wireless communication system are provided. The method includes examining whether there exists an accessible target network while communicating with a serving network; when there exists the accessible target network, linking up to the target network; changing a communication state to an idle mode by de-registering the linked target network; and performing a network re-entry to the target network in a vertical handover to the target network. When the terminal can execute the vertical handover without the seamless service support and reduce the handover delay.
