摘要:
When an incoming call corresponding to a communication number PID takes place in a switching station, the switching station retrieves user-intrinsic information UK and an incoming-communication registered terminal identification number SID and sends the communication number PID to a communication terminal. When the communication terminal replies, the switching station generates a random number R and sends it to the communication terminal. In addition, the switching station generates a cryptical key K=F (R, UK) corresponding to the user-intrinsic information UK and the random number R. The communication terminal generates a cryptical key K=F (R, UK) corresponding to the received random number R and the user-intrinsic information UK that is input by the user. The switching station and the communication terminal encrypt the communication information corresponding to the cryptical key K and decrypt received encrypted communication information.

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.

A switching center 30 comprises a memory part M2, a memory part M3, and a memory part M4. The memory part M2 stores a terminating terminal number corresponding to and registered by each subscriber. The memory part M3 stores idle/busy information corresponding to each terminal. The memory part M4 stores idle/busy information corresponding to each subscriber. When a subscriber 11.sub.1 makes a call at a terminal 12.sub.2, the switching center 30 determines whether the idle/busy information for the subscriber 11.sub.1 stored in the memory part M4 is idle or busy. When the idle/memory information represents idle, the switching center 30 refers to the idle/busy information for the terminal 12.sub.2 stored in the memory part M3. When this idle/busy information represents idle, the switching center 30 reads out the terminal number of a terminating terminal of a terminating subscriber stored in the terminating terminal memory part M2 and performs an outgoing call connection process. At this point, the switching center 30 also sets the idle/busy information for the subscriber 11.sub.1 and the terminal 12.sub.2 to busy state. When the subscriber 11.sub.1 makes a call, while the terminating terminal 12.sub.1 is performing an incoming call connection process for the subscriber 11.sub.1, since the idle/busy information for the subscriber 11.sub.1 has been set to the busy state, even if the terminal 12.sub.2 is idle, the switching center 30 does not perform an outgoing call connection process for the subscriber 11.sub.1 at the terminal 12.sub.2.

In a mobile communication network comprised of a plurality of switching devices and a plurality of base stations connected to the switching devices, while a mobile terminal to wirelessly communicate with the base stations is in a communication by a soft handover, a terminal endpoint of a protocol for control of the soft handover is relocated in changing a switching device to another as a branch/combining point of data on a communication route of the communication.

There is provided a communication system and a communication method of making available both a shared telephone number shared by multiple communication terminals and an individual telephone number dedicated to a user's own terminal in a single communication terminal. A shared managing unit 11 of a communication system 1 manages terminal identifiers 1 and 3 identifying each of a plurality of communication terminals 30a and 30b to which a shared telephone number is assigned in correlation with the shared telephone number. An individual managing unit 12 manages a terminal identifier 2 identifying a communication terminal 30b to which an individual telephone number is assigned is correlation with the individual telephone number. A user information managing unit 13 manages user information including base station information of communication terminals identified by the identifier every terminal identifiers 1, 2, and 3. A call control device 20 carries out call control of communication terminals 30b, to which the shared telephone number and an individual telephone number are assigned, using this information.

There are provided a server apparatus capable of transmitting any message in a flexible manner at various timings of communication service states, and a message transmission method thereof. When a communication trigger detector 103 of an IMS 100 detects a trigger point, a determination portion 104 determines a massage to be transmitted based upon at least one of a type of the communication service state, a transmission destination of the message, presence information, and an instruction input. A message transmitter 105 give an instruction to an information storage device 300 to transmit the message to be transmitted that has been determined, and the information storage device 300 transmits the message to the transmission destination.

There are provided a video editing system, a video editing server and a communication terminal which enable simultaneous editing operations for editing a video content to be performed by plural persons, without generating a file in which a content of the editing has been reflected in the video content. One of a plurality of editing terminals in a synchronized state generates an edit command for editing a video content with an edit command generating section, based on an editing operation by a user from a terminal operating section, and transmits the generated edit command to a video editing server via an information transmitting/receiving section. If the edit command is received via an information transmitting/receiving section, the video editing server transmits the received edit command to another editing terminal in the synchronized state, via an edit command synchronizing section. If the edit command is received via the information transmitting/receiving section, another editing terminal in the synchronized state displays a content of the edit command on a screen displaying section via an edit command displaying section.
