The terminal of the requester implements a function transmitting a position tracking service request to a mobile communication system(300). A tracing image data acquiring unit(200, 200') receives the beacon signal and acquires tracking image data.

Abstract: A method for sharing information between mobile terminals in a multi-hop relay-based mobile communication system is provided to reduce resource allocation of a mobile communication network and shorten time for downloading information. A mobile terminal receives particular information, for example, contents, etc., from a different mobile terminal or from a mobile communication network via a base station and stores it in an internal memory whenever the information is used(S100). The first mobile terminal located in the first cell checks whether it has corresponding contents information according to a user request for using the contents information(S200,S300). If the first mobile terminal has the corresponding contents information in an internal memory, the first mobile terminal uses the contents information, changes a usage time of the corresponding contents information to a current time, and is terminated(S400,S500).

Abstract: A call admission control method using a cell matrix in a mobile communication system and an apparatus thereof are provided to minimize a call loss rate abruptly increased in the whole of a BSC(Base Station Controller) by forming a cell matrix for all the cells of the BSC, grating a weight to each of the cells, calculating traffic density of the BSC by using the cell matrix and the weights, and suppressing an excessive traffic given to the BSC. An interference collection part periodically collects cell-by-cell interferences through the traffic information received from the cells of a BSC(s1). A weight providing part extracts previously appointed group-by-group weights(s2). A cell matrix configuration part forms a cell matrix using the collected interferences(s3). A traffic density calculation part multiplies the cell matrix by the weight vectors provided from the weight providing part and calculates the traffic density of the BSC(s4). A call admission rate adjustment part compares the calculated BSC traffic density with the maximum allowable call admission threshold of the BSC(s5). In case that the calculated BSC traffic density is larger than the maximum allowable call admission threshold, the call admission rate adjustment part searches the cell matrix for a cell having the maximum interference(s6).
