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.

An apparatus for managing components in an SCA system includes a naming context tree having one or more directories. Each directory has an ID, the ID is assigned to a component to be registered, and the component is registered in the directory having the ID and unregistered from the directory. The apparatus further includes a name server for managing the components registered in the directories of the naming context tree.

A buffer includes a pull-down means, a pull-up means, and a control signal generator. The pull-down means generates an output signal that transitions to a first state at a relatively high speed when an input signal transitions from a first state to a second state in response to a control signal at a first control state. The pull-up means generates an output signal that transitions to the second state at a relatively high speed when an input signal transitions from the second state to the first state in response to a control signal of a second control state. The control signal generator produces the control signal as a function of the output signal. Accordingly, the buffer can transfer an input signal at a high speed in both cases of a high-to-low transition of the input signal as well as a low-to-high transition of the input signal.

A method and apparatus for avoiding a collision of an uplink preamble using a cell identifier. In a case of installing a new small-sized base station in a mobile communication system, the method and apparatus may set a code parameter, a time parameter, and a frequency parameter, differently from a neighboring small-sized base station using the cell identifier even when dedicatedly using a preamble in a contention-free scheme to avoid a collision of the preamble, so that a random access preamble may be managed without occurrence of the collision with the neighboring small-sized base stations.
