摘要:
A mobile communications system for transferring packets to a mobile communications terminal according to address information of the mobile communications terminal is disclosed. The mobile communications terminal is located in a moving network connected to a given node in a core network. The address information of the mobile communications terminal includes common information related to the given node to which the moving network is connected, and individual information which is unrelated to the given node to which the moving network is connected and is unchanged when the given node to which the moving network is connected is changed.

A network management server includes an address manager and an address assignment direction transmitter. The address manager manages a first address, a second address and a third address of the destination mobile terminals in accordance with address assignment information received from a mobile node. The address assignment direction transmitter transmits an address assignment directions for directing a source access node to manage the first address and the second address of the destination mobile terminal, and to transmit an address assignment direction for directing a destination access node to manage the second address and the third address of the destination mobile terminal.
摘要:
A mobile communications control method of this invention controls mobile communication by a mobile terminal in a network in which a plurality of wireless systems are available. In the mobile communications control method, the mobile terminal performs location registration with a wireless system selected from among the wireless systems, based on at least one of a status of the network, a status of the mobile terminal, location information of the mobile terminal, a frequency of incoming call reception of the mobile terminal, and service area information of the wireless systems.
摘要:
A mobile communication network system is provided in which when a radio system is selected from plural types of radio systems as a radio system for use in paging, the optimum radio system for the mobile terminal to be paged can be selected. When it is selected, traffic does not concentrate on a specific radio system, or no excess delay occurs when the mobile terminal starts communications. When the mobile communications network system performs paging as a paging notification to a mobile terminal through any one of various radio systems under a communications environment in which radio waves of various radio systems having different communication systems are used, a radio system is selected from a plurality of radio systems depending on the application used in the communications of the paging requested mobile terminal and a paging operation is performed through the selected radio system when a paging request is issued.
摘要:
A radio data communications method capable of changing control points located in a network without causing loss of data when a mobile terminal is performing a soft handover. In the radio data communications method in which at least one of a first radio network controller and a second radio network controller performs a soft handover process for allowing a soft handover of a mobile terminal when the mobile terminal is performing soft handover, in downlink radio data communications in which the first radio network controller transmits data to a mobile terminal via a second radio network controller and a base station (or in uplink radio data communications). The first radio network controller or the second radio network controller performing the soft handover process is changed when the mobile terminal is performing the soft handover.
摘要:
A mobile terminal can be loaded with a plurality of subscriber identity module cards at the same time, and register the condition to a mobile communication network. The mobile terminal comprises detects a loading of a recording medium (such as an IC card like the SIM card), and transmits, when the detecting means detects at least two recording media, first subscriber identity information (e.g. IMSI, TMSI, etc.) corresponding to a first recording medium and second subscriber identity information corresponding to a newly detected recording medium, to the subscriber information management apparatus such as a visitor location register (VLR). The subscriber information management apparatus registers location area information of the first subscriber identity information as location area information associated with the second subscriber identity information.
摘要:
In a mobile communication network, a mobile unit location register ML and a subscriber location register SL are provided. In the mobile unit location register the mobile location of a mobile unit MT is registered, whereas in the subscriber location register a mobile unit MT selected by each subscriber SB as a terminal for call terminating use is registered. Upon receiving a terminating call for a subscriber, a switching center SW reads out, from the subscriber location register SL, an identifying number TID of the mobile unit registered by the subscriber SB as a terminal for call terminating use and uses the mobile unit identifying number TID to read out the mobile location of the mobile unit MT from the mobile unit location register ML, thereafter sending the terminating call to the registered mobile unit of the read-out mobile location.
摘要:
A network control system, which controls connections between a mobile terminal and multiple types of wireless systems accommodated in a network, includes a prescribed node provided on the network. The node comprises signal transmitting/receiving means that transmits and receives a control signal defined by each of the wireless systems, protocol converting means that converts the control signal to a common protocol independent of each of the wireless systems, and entity communication controlling means that communicates with multiple functional entities provided on the network, using the common protocol, to implement network control.
摘要:
A system for controlling handover is disclosed that includes a mobile terminal that enables communications with multiple wireless systems having wireless access stations, and a handover-controlling apparatus that executes control of handover for the mobile terminal, which travels among multiple types of wireless systems. The mobile terminal includes a destination wireless system determining unit that receives downlink signals from the corresponding wireless access stations so as to determine which wireless system accommodates a destination wireless access station based on reception quality of downlink signals. The mobile terminal also includes a destination wireless system reporting unit that sends information indicating the determined wireless system to the handover-controlling apparatus. The handover-controlling apparatus includes a handover-controlling unit that controls handover operations for the mobile terminal based on the information indicating the determined wireless system, which is sent from the destination wireless system reporting unit.
