Title: Process for producing optically active isomers of tricyclic compounds
Inventor: NAGASE HIROSHI
IPC: C07D307/935
Filed: 1998-02-19
Abstract: Optically active isomers of tricyclic compounds, typically cyclopenta¢b!benzofuran derivatives represented by general formula (II) wherein R1, R2, Y and Z each represents hydrogen, halogeno, alkyl, or aryl; W represents oxygen, sulfur, nitrogen, or carbon; and n is 0 to 4, and directly produced by adding an optionally active alcohol, amine, or/and metal salt thereof.

Title: A method of providing a delayed connection announcement to a mobile subscriber within a radio telecommunication system
Inventor: BERTACCHI LUCIANO
IPC: H04M3/46
Filed: 1997-10-28
Abstract: A method is disclosed for alerting a mobile subscriber within a radio telecommunication system to wait for the connection of an incoming call which may have a delayed connection time due to network congestion or the implementation of flexible alerting features utilizing alert-and-answer-before-routing techniques. In flexible alerting extension phone service, each one of a plurality of mobile stations is assigned to a single pilot directory number (PDN), and a home location register (HLR) (12) in an originating exchange maintains a list of parameters identifying each visited mobile switching center (V-MSC) (13-15) in which mobile stations identified with the PDN are believed to be currently located. The HLR (12) places a forward service indicator code in the routing request messages (22) that it sends to the V-MSCs (13-15). After all mobile stations identified with the PDN are paged, voice channels (26) are sized with those that responded. Alerting signals (29) are sent to responding mobile stations, and the V-MSCs transmit a delayed connection message (34) to the answering mobile stations. While the V-MSCs (13-15) return routing numbers to the HLR (12), the message (34) may be repeated periodically. If more than one routing number is returned to the HLR, the HLR selects a single mobile station to receive the call. The delayed connection announcement (34) is stopped when a voice trunk (41) is established between the originating MSC (11) and the V-MSC (15) serving the selected mobile station (28).
