摘要： A method for providing a multicast service from a macrocell or a microcell to a mobile station in a mobile communication system having a hierarchical cell structure in which a given area is divided into at least one macrocell and at least one microcell overlapping with each other. The mobile station receives a multicast service by accessing the macrocell or the microcell according to a carrier-to-interference ratio (C/I) for the multicast service measured in a macrocell area and according to an existence or non-existence of a concurrent call currently in service. When there is no concurrent call currently in service, the mobile station receives the multicast service by accessing the macrocell in an area where the measured C/I is equal to or greater than a required C/I. However, when there is a concurrent call currently in service, the mobile station receives the multicast service by accessing the macrocell or the microcell based on the current cell and the C/I.

摘要： Disclosed is a method and apparatus for cell selection, which can prevent the occurrence of an error in the cell selection in a mobile communication system supporting the hierarchical cell structure. The method includes: when the number of times of cell reselection during a cell reselection time period given to a particular User Equipment (UE) located within a micro cell exceeds a predetermined maximum number of times, determining if a sum of actual occupancy time intervals of the particular UE in Node Bs, services of which the particular UE has used up to then, is smaller than a predetermined value; and when the sum of actual occupancy time intervals of the particular UE in Node Bs, services of which the particular UE has used up to then, is smaller than the predetermined value, determining that the UE is in a low speed state and maintaining the micro cell as a service cell for the UE.

摘要： Disclosed are an apparatus and a method for preventing the degradation of RF performance due to a change in impedance of an antenna in a mobile communication terminal. The mobile communication terminal includes a plurality of impedance matching circuits and a controller of the mobile communication terminal is adapted to measure the reflection voltage of the antenna, select one impedance matching circuit corresponding to the measured reflection voltage, and connected with the antenna through the selected impedance matching circuit. As a result, when the impedance value of the antenna is changed, it is possible to prevent the degradation of performance of the RF module of the mobile communication terminal by using an impedance matching circuit, which can optimize the reflection loss caused by the reflection voltage of the antenna according to a change in impedance value.
