Abstract:
PURPOSE: A mobile terminal and a method for processing hand over using inter rat are provided to utilize inter RAT(Radio Access Technologies) neighbor list as neighbor list for femto cell, thereby performing inter-cell reselection and hand over process. CONSTITUTION: A mobile communication terminal receives broadcasting information(S10). The mobile communication terminal confirms inter RAT(Radio Access Technologies) list(S20). If the inter RAT list is defined, the mobile communication terminal inquires inter RAT cell information list(S30,S40). The mobile communication extracts neighbor list information among information items of broadcasting information(S50). The mobile communication terminal performs a hand over processing(S60).
Abstract:
PURPOSE: An apparatus and a method for interfacing a call between a local phone network and femto cells based on WCDMA are provided to connect femto cells to an IP-PBX by a SIP protocol in order to enable the connection to an in-house phone network or PSTN(Public Switched Telephone Network) terminal. CONSTITUTION: An MSC(Mobile Switching Center) unit(201) performs the role of an MSC for a femto cells, and processes lu signal depending on a lu-CS protocol. An SIP(Session Initiation Protocol) unit(203) is operated as a SIP UA(User Agent) for an IP-PBX(Internet Protocol-Private Branch eXchange)(101). An IWF(Interworking Function)(205) converts the lu signal into an SIP signal. In addition, the IWF converts the IMSI(International Mobile Subscriber Identity) of a corresponding wireless terminal into an SIP URI(Uniform Resource Identifiers).
Abstract:
PURPOSE: A packet service providing supply system and a charging server of a packet service using a small-sized base station are provided to supply a charge about the packet service if a sending terminal and a receiving terminal are located within a coverage of the base station. CONSTITUTION: If originating service region discrimination information and terminating service region identification information are coincide with each other, a charging method setup unit(250) sets up the charging plan information of the packet service. If the charging plan information is instituted on discount, a charging unit(260) discounts and supplies use charge for free. The discounted charge is disposed to one among the calling terminal and called terminal.
Abstract:
A handoff method in heterogeneous service networks is provided to reduce a service charge and increase user's convenience such as supplementary service activation, and accelerate network development through competition between providers. A handoff method in heterogeneous service networks comprises the following steps. A terminal analyzes a data use pattern at regular periods, and measure the used rates of a transmission mode, a reception mode, and an idle mode of first and second wireless interfaces, and estimates the use rate of the future with respect to each mode(S1). Handoff to a wireless interface having the minimum costs is performed based on data use rates in the first and second wireless interfaces according to the use rates of each mode, which is estimated in the above step, when a terminal is connected to the first interface. Handoff to the first wireless interface is performed if the receiving signal strength of the second wireless interface is less than a threshold value when the terminal is connected to the second interface(S4,S5,S6).
Abstract:
An apparatus and a method for controlling traffic handover in a multi-mode mobile communication terminal are provided to receive IMSI information even without connecting a USIM(Universal Subscriber Identity Module) in the second network communication mode when the traffic handover from the first network communication mode to the second network communication mode occurs in the dual mode mobile communication terminal, thereby reducing a handover processing time and enhancing a handover success rate. An apparatus for controlling traffic handover in a multi-mode mobile communication terminal comprises the followings: the first processing module(216); the second processing module(213) of which an inter chip path is connected with the first processing module(216); and an application processor which controls the first processing module(216) so as to transmit an IMSI(International Mobile Subscriber Identity) to the second processing module(213) when a traffic handover event from the first mode to the second mode occurs.
Abstract:
PURPOSE: An apparatus and a method for switching frequency bandwidth are provided to improve terminal transmitting-and-receiving performance by resonating antenna to WCDMA(Wideband Code-Division Multiple) frequency bandwidth while terminal enters a cell of mobile communication system by WCDMA. CONSTITUTION: A decider(330) determines communication mode which is provided to current cell by referring a received message. A band converter(340) resonates frequency bandwidth of antenna to frequency bandwidth for reestablished communication method. The communication method is determined by referring at least one of MIB(Master Information Block) and SIB(System Information Block) which is included in a message.
Abstract:
A method for performing handover between an IEEE 802.16 network and an UMTS network and an apparatus thereof are provided to be easily combined with modules implemented as hardware and software. A method for performing handover between an IEEE 802.16 network and an UMTS network comprises the following steps of: requesting an IEEE 802.16 modem to establish an IEEE 802.16 link(202); reporting the attempt for establishing the IEEE 802.16 link to an MIH entity(206); making the MIH entity start the MIH session(222); informing the MIH entity that a layer 2 connection is terminated within a specific time interval through the third API; and making the MIH entity activate an UMTS modem for handover.
