Abstract: PURPOSE: A method for controlling a power saving mode of a mobile communication system is provided to lengthen a paging cycle according to a battery remaining amount or by a user, thereby lengthening a local update cycle. CONSTITUTION: A location managing server generates a new current paging cycle value based on received power saving mode information(S40). A mobile communication terminal receives the current paging cycle value through a base station and an MME(Mobility Management Entity)(S42,S44). The mobile communication terminal resets a paging cycle and a location update cycle which are set before(S46). The mobile communication terminal reduces power.

Abstract: PURPOSE: A handover apparatus between heterogeneous networks and a method thereof for supplying a seamless service by reducing data loss are provided to reduce handover time delays by selecting an optimal mobile network based on information collected from a system. CONSTITUTION: A previous register(110) compares a SNR(Signal to Noise Ratio) of a first network with a first threshold value. If a first relational condition is satisfied, the previous register performs a previous registration procedure to a target network. A handover performer(120) compares the signal-noise ratio with a second critical value. If the second relational condition is satisfied, the handover performer performs a handover procedure to the target network.

Abstract: A method and a system for authenticating an IMS(Internet Multimedia System) in a mobile Internet are provided to decrease a signaling overhead in wireless/wire sections by using a master session key for authenticating the IMS. A system for authenticating an IMS in a mobile Internet includes a base station(120), a control station(130), and a CSCF(170). The base station wirelessly communicates a basic connection authentication related message and an IMS authentication related message with a mobile terminal. The control station is connected to the base station to communicate the basic connection authentication related message and the IMS authentication related message with the base station and provides IMS-MSK field values for users of plural mobile terminals. The IMS-MSK(Master Session Key) field value is an MSK field value generated during a basic connection authentication process for using a mobile Internet service in the mobile terminal. The CSCF(Call State Control Function) is connected to the control station, communicates the IMS authentication related message with the control station, and processes an IMS authentication of the mobile terminal requesting the IMS service by using the IMS-MSK field value.
