A method for managing neighbor cell interference comprises: a step of measuring inter-cell interference control information by subframe units; and a step of transmitting the inter-cell interference control information measured by subframe units, to at least one neighbor cell for each of the subframes. The interference management method of the present invention dynamically performs neighbor cell interference management under the condition where neighbor cell interference changes in terms of time, thus improving performance of a system. Further, the interference management method of the present invention maps a wireless resource property pattern to a cell ID. Consequently, the system adopting the method of the present invention exhibits excellent performance in any environment.

An apparatus and method for assigning a Physical Cell Identity (PCI) of a Home eNodeB (HeNB) are provided. The apparatus may distribute PCIs into a plurality of PCI groups, and may enable a PCI group to be assigned to a cell so that the assigned PCI group may be different from a PCI group assigned to a neighboring cell, and that an unassigned PCI in the assigned PCI group may be assigned to an HeNB within a single cell.

Provided is a method and apparatus for avoiding a collision of a preamble in a base station. When a new base station is installed in a mobile communication system and in this instance, an exclusive preamble using a contention-free scheme is employed to avoid a preamble collision, at least one of a code parameter, a time parameter, and a frequency parameter used in a preamble of the new base station may be set to be different from a code parameter, a time parameter, and a frequency parameter used in a preamble of a neighboring cell, whereby it is possible to manage a random access preamble without causing a collision between cells.

Provided are a method and an apparatus for power saving of a femto base station operating as a CSG cell in a wireless communication system. A femto base station according to an exemplary embodiment of the present invention includes: a reception unit receiving signals from adjacent second femto base stations; a transmission unit transmitting signals to second femto base stations, and a control unit controlling to be transitioned to an active mode when a mode transition command is received from at least one second femto base station while operating in a sleep mode, in a wireless communication system constituted by a plurality of femto base stations using automatic neighbor relation (ANR).
摘要:
The present invention relates to a software communications architecture (SCA)-based system, and a file parsing method and an application generation method thereof. In the present invention, the SCA-based system integrates parsers related to application driving into one parser to generate one integration parser, and implements a parser manager that executes an integration parser function by a common object request broker architecture (CORBA) component. Therefore, when the other manager components need information of descriptor files related to application driving, the other manager components request it from the parser manager of the corresponding information without generating a new parser, and the parser manager provides the corresponding information to the other manager components.

A download server that transmits, when it receives a request of one or more application programs from a client device, to the client device connected to the download server via a wired or wireless network the application programs includes a dependency analyzer, a partitioned shared library generator and a controller. The dependency analyzer that analyzes a dependency of each of the application programs on existing shared libraries to detect object codes, which are actually used by corresponding application program, in the existing shared libraries; the partitioned shared library generator that generates, based on the analyzing result of the dependency analyzer, partitioned shared libraries having only the actually-used object codes; and the controller that transmits, by using a connection module, partitioned shared libraries selected from the generated partitioned shared libraries, and the application programs linked thereto to the client device via the network.
摘要:
A method for controlling an operation and management subsystem in a signalling message exchange No.1 system, the operation and management subsystem including a user interface subsystem, a target interface subsystem, an operation control subsystem, a signalling network operation system interworking subsystem, an operation and management subsystem management subsystem and a data management subsystem. The method includes the steps of when the operation and management subsystem being at an idle state receives a message from the target system, converting the message by the target interface subsystem into a format for a selected one of the subsystems of the operation and management subsystem on the basis of a module identifier value of the message and then executing a control associated with the message by the selected subsystem, while when the operation and management subsystem being at the idle state receives a message from an operation and management worksite, converting the message by the user interface subsystem into a format for a selected one of the subsystems of the operation and management subsystem on the basis of a module identifier value of the message and then executing a control associated with the message from the user interface subsystem in the selected subsystem.
