A versatile system for controlling and managing resources for Soft Handoff Group operations is disclosed. The system determines which of a plurality of sectors in an access network is a serving sector for an access terminal. An active set of the plurality of sectors is assigned to the access terminal, comprising the serving sector. A soft handoff set for the access terminal is identified from the active set. A soft handoff group for the access terminal is identified from the soft handoff set. The access terminal's transmissions within the access network are managed according to the identified soft handoff group.

A service restriction apparatus and method for a portable phone. A utilization restriction method for a portable communication device includes determining whether a service restriction function is activated when an incoming or outgoing call request is detected; determining whether a phone number of the incoming or outgoing call is registered in a communication-allowed phone number list if a service restriction function is activated; attempting to process the incoming or outgoing call if the phone number is registered in the communication-allowed phone number list; and blocking the incoming or outgoing call if the phone number is not registered in the communication-allowed phone number list.

The present invention relates to a method for controlling a data rate for a forward data service in a CDMA 2000-1x system. Conventionally, the data rate from a base station to a mobile station is constant regardless of the wireless environment of the mobile station. As such, resources used in the base station for communication with the mobile station may be wasted if the data throughput is low due to the poor wireless environment. The present invention, however, resolves this problem by varying the data rate according to Energy of Carriers/Interference of Others' (Ec/Io) of the data, which indicates the wireless environment of the mobile station. With the present invention, the resources in a base station, which would be wasted for communication with a mobile station in a poor wireless environment, can be used for other mobile stations. Thus, the resources of the overall CDMA 2000-1x system can be used efficiently.

A phase-locked loop (PLL) for stably adjusting a frequency band of a voltage-controlled oscillator and a phase locking method. In the PLL, a frequency band controller alters the frequency band selection digital value in response to an input clock signal and an oscillation control signal generated from an LPF of a basic PLL circuit, and thus a voltage-controlled oscillator of the basic PLL circuit alters the frequency of an output clock signal in response to the oscillation control signal and the frequency band selection digital value. The output clock signal is rapidly and stably phase-locked at a target frequency depending on the frequency band selection digital value.

The invention provides a lens transfer device including at least one lens and a lens barrel. The lens barrel has a lens receiving part with the lens arranged in an inner space thereof and an extension extending radially from an outer surface of the lens receiving part. An actuator has a body and an output member at a leading end of the actuator to contact the extension, and is adapted to expand/contract and bend in response to an external supply voltage to provide a driving force necessary for transfer of the lens barrel through the output member. A pressing member has a free end contacting a rear end of the actuator to force the actuator against the extension, and a guide guides the transfer of the lens barrel along an optical axis.
