Abstract: A first editing application is prepared in a label printer 1 in order to expand data into substantially the same format as that displayed on a display 3 of a computer 2 and print the data expanded on a label L even where the computer 2 is not connected to the label printer 1. If the computer 2 is connected to the label printer 1, a second editing application prepared in the computer 2 is employed. On the other hand, if the computer 2 is not connected to the label printer 1, the first editing application is employed in order to expand the data into substantially the format as that displayed on the display 3 of the computer 2 and print the data expanded on the label L.

Abstract: A scheme for enabling a roaming call termination connection for a mobile subscriber between mobile communication networks adopting different roaming number allocation schemes is disclosed.

Abstract: A mobile communications system including a plurality of communications networks, each of which has one location register (a home location register or gate location register) and one or more visitor registers. Each of the visitor registers is located in each one of visiting areas for storing information about a communication terminal. The location register stores the number of the visitor register of the visiting area in which the communication terminal is present, and the information about the communication terminal. When the communication terminal moves between the communications networks, the information about the communication terminal is transferred between the location registers. When the communication terminal moves between the visiting areas in the same communications network, the information about the communication terminal is provided from the location register to the visitor register.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A manual printer has a casing of a shape suitable for mounting on a table, a guide rail installed in the casing, a guide member movably connected to the guide rail, a base supported on the cursor and projecting outwardly through a front opening of the casing, a printing head attached to the base, a controller contained in the casing, a switch panel installed in the casing, a display secured to the casing so as to display printing data, and an ink ribbon cassette arranged in the base. In a printing operation, an operator inputs the printing data to the memory of the controller and the base is moved by hand along the guide rail in order to have the printing head print words and the like onto paper sheets.
