A method uses inter-base station control messages to provide neighbor base station information to mobile subscriber stations in a mobile communication system. The method includes obtaining, at a serving base station, physical channel information of neighbor base stations over a backbone network via, either directly or via a server; periodically transmitting the obtained physical channel information from the serving base station to a mobile subscriber station connected to the serving base station; and measuring, based on the updated physical channel information, signal quality of the at least one neighbor base station at the mobile subscriber station. Thus, the serving base station receives from the neighbor base stations the inter-base station control messages containing the neighbor base station information, updates the information, and provides the updated information to the corresponding mobile subscriber station(s), to be used for a specific purpose such as handover or network entry.

The present invention is related to transmitting quality of service (QoS) information of a target base station for admitted service flows during a handover operation. The invention comprises providing a service to a mobile station from a serving base station and receiving at the serving base station a handover request from the mobile station. The serving base station the provides a handover notification to a target base station, wherein the handover notification comprises a QoS parameter associated with the service. The serving base station then receives from the target base station a handover notification response, wherein the handover notification response comprises service level prediction information that is determined in response to the QoS parameter associated with the service. Finally, the serving base station provides a handover response to the mobile station, the handover response comprising the service level prediction information.

Disclosed is a SRAM cell and a method of manufacturing the same. The SRAM cell comprises: a pair of access devices; a pair of pull-up devices; a pair of pull-down devices; and at least one metal plate formed on metal interconnection lines in contact with a substrate, having a dielectric film interposed between the metal plate and the metal interconnection lines, so as to increase a cell capacitance, thereby reducing a soft error rate. Herein, one metal plate may be included in each cell. In this case, the metal plate overlaps with a first one of metal interconnection lines of a node side and a node bar side, while being in contact with a second one of the metal interconnection lines of the node side and the node bar side. Also, two metal plates may be included in each cell. In this case, the metal plates overlap, respectively, with one metal interconnection line of metal interconnection lines of a node side and a node bar side, while being in contact with another metal interconnection line of the node side or the node bar side, respectively. Therefore, capacitance is additionally formed to increase cell capacitance, so that variation of the electric potentials of cell nodes, which is caused by generated electrons, is prevented, and thereby soft error can be efficiently reduced.
