摘要： PROBLEM TO BE SOLVED: To obtain an ISDN communication system having high line efficiency and reliability. SOLUTION: When a user performs calling communication to a center 3 side from a meter 13 side by using user/user information communication service, there are cases where a user exchange 9 of a network sometimes decides it as congestion, so that the meter 13 side may receive response corresponding to the condition of being in the midst of a conversation. For instance, an NCU 11 sets telegraphic message to a UUI(user/user information) of a SETUP message and transmits the SETUP message to the user side exchange 9 (step 204). While the exchange 9 decides it as congestion, the exchange 9 returns a REL 21 (release) message, where busy 28 or usable line unavailable channel 29 is set to a reason flag 27 corresponding to the condition of line being busy (step 206). Congestion is decided from the REL 21 (release) message received by the NCU 11, and a retry is performed after prescribed time that is shorter than a normal retry passes, (e.g., four seconds) (step 208). When the response corresponding to the condition of line being busy is received, the NCU 11 repeats retries for a prescribed number of times.

摘要： PROBLEM TO BE SOLVED: To manage and make use of market information on real estate at a low cost and easily. SOLUTION: A real estate information management support system 1 is composed of a plurality of user terminals 2, a system server 3 and a database 4. The database 4 stores the map data of digital maps, city planning maps or the like, and the attribute data of official announcement of land price, land assessments, land price research, national census, station information, information on property for sale, or the like. When selecting a building lot for real estate, the system server 3, on the basis of the map data and the attribute data, summarizes, for each sphere of train station, the number of commutation passengers getting on and off at the station that a user in an arbitrary area has designated, the number of existing condominiums, the tendency of change in households, and the like, and displays the summarized result together with the map of the area that the user has designated on the user terminal 2. The user, by analyzing the summarized result, can efficiently select a hopeful candidate lot.

摘要： PROBLEM TO BE SOLVED: To solve a problem of an increased reply time in the case of continuously transferring user-user information by receiving the user-user information included in a setup message, confirming the validity of the reception of an incoming call, then immediately returning a call message and succeedingly transmitting a disconnection message so as to restore the disconnection. SOLUTION: When a terminal receiving a call setup message including user- user information(UUI) from a center via a network discriminates the call to be its own incoming call on the basis of a caller number, a caller sub address or contents of the UUI or the like described in the SETUP information, the terminal transmits a call massage (ALERT) to the center and then transmits a disconnection message (DISC) to the network. The called terminal receives a release message (REL) from the network and transmits a release completion message (REL COMP) to the network and is restored a standby state. Since the terminal receiving an incoming call transmits the ALERT to the center immediately after confirming the validity of the incoming call, the center can confirm that the terminal receives the UUI.

摘要： PROBLEM TO BE SOLVED: To obtain an ISDN communication system that allows automatic switching between UUI communication and B channel communication. SOLUTION: When a center 3 side, using a B channel communication system calls on a terminal side, first, communication is performed by a D channel. That is, the center 3 transmits a meter reading request to a line IF 4 (step 201). The line IF 4 sets communication system information representing the B-channel communication system to the caller sub address or the receiver sub address of a SETUP message 21 and transmits the SETUP message to an I-NCU 9 via an ISDN public line (step 202). The I-NCU 9 receives communication system information 37 of the received message 21, recognizes it as the B channel communication system and receives it (step 203). Subsequently, the I-NCU 9 performs communication by using the D channel and the B channel as the B-channel communication system set to the received information 37 (step 204 to step 218).

摘要： PROBLEM TO BE SOLVED: To obtain an ISDN communication system capable of continuously performing call out and reception to a specific center slave unit at a terminal in a center, having plural slave units utilizing UUI(user-user information) communication. SOLUTION: When a center 3, having plural lines is called from a terminal side, an NCU 9-1 of the terminal side first calls with a main telephone number A of a center 3 (step 200 and step 201), and a main selection device 5 of a center 3 side makes a center slave unit other than a center master unit 3-1, e.g. a center slave unit 3-2 receive (step 202). The receiving unit 3-2 attaches calling telephone number information, to which the telephone number B of the unit 3-2 is set to a UUI(user-user information) packet and answers the terminal side with it (step 210 to step 212). After that, the terminal side performs UUI(user-user information) communication with the calling telephone number B (step 220 to step 222).

摘要： PROBLEM TO BE SOLVED: To reduce the power consumption of the system and to decrease the number of components by sampling digital data on a transmission side with a clock faster than the clock of the data and transmitting them as high- speed digital data, and detecting the envelope of a received signal on a reception side. SOLUTION: A T-NCU 9 transmit low-speed digital data received from a meter 11 at a low communication speed through a high-speed digital communication port through a digital line 7 for high-speed digital line 7. A reception-side line IF 5 demodulates the received signal by envelope detection and the line IF 5 of a center 3 sends the low-speed digital data as the low communication speed through the high-speed digital communication port through the digital line 7. A reception-side T-NCU 9 demodulates the received signal by envelope detection and sends the low-speed digital data to the meter 11.
