  • Patent number: 7505783
    Abstract: A method, apparatus and a computer readable record media storing instructions for executing the same method for interfacing among a hybrid type synchronous or asynchronous terminal to a core network in a next generation mobile telecommunications system. The hybrid type synchronous or asynchronous radio network determines the operating type of the core network when the core network has a connection thereto, and sends the determined core network operating type information and information related to the core network to the hybrid type synchronous or asynchronous terminal, thereby allowing the synchronous or asynchronous terminal to smoothly perform a data interfacing operation with the core network.

  • Patent number: 7505737
    Abstract: Disclosed is an apparatus for generating a stable clock signal having a Long term jitter noise removed therefrom. In a mobile communication terminal having a power management chip for converting a sinusoidal wave oscillated in a crystal into a clock signal of square wave, the sinusoidal wave is converted into a square wave clock signal by the stabilized driving power having no alternating current components, and thus a power noise of the square wave clock signal is removed. Then, the square wave clock signal having the power noise removed therefrom is outputted after a predetermined delay time. Accordingly, it is possible to supply the clock signal having the Long term jitter noise removed therefrom and synchronized to each device in the mobile communication terminal.

  • Publication number: 20080287133
    Abstract: Disclosed are a soft handoff system, a soft handoff method, and a mobile terminal equipped with the soft handoff system. The soft handoff system for a mobile terminal analyzes periodically monitored wireless conditions of neighbor base stations, transmits a PSMM (Pilot Strength Measurement Message) to a current base station when a condition arises that needs reporting to the current base station, receives an HDM (Handoff Direction Message) from the current base station, wherein upon receiving the HDM from the current base station, the system allows a handoff drop timer of an active base station belonging to an active set having a pilot channel signal strength less than a predetermined value to continue running rather than to be reset until the handoff drop timer expires.
