Title: Packet communication network
Inventor: SAITO YUKICHI
IPC: H04W92/02
Filed: 1998-10-30
Granted: 2007-01-16
Abstract: Control of a packet communications network in a fixed network used by a mobile communications network is provided. (1) A communication hold mode is set for a user when the traffic volume of the user's transmission or reception of a packet per fixed time period is less than a predetermined value. The communication hold mode is defined as "although the network resources are released once, a mobile station and a gateway center at an interface with an external network behave to the user side and the external side as though the communication hold mode were maintained". (2) When the user in the communication hold mode restarts the transmission of a packet, the mobile station automatically carries out a recall processing without the intervention of the user, and reestablishes the communication up to the gateway center. (3) When the gateway center restarts receiving a packet to the user in the communication hold mode, the gateway center carries out the incoming recall processing without the intervention of the external network, and reestablishes the communication all the way to the mobile station. (4) To accomplish the incoming recall processing, the mobile station makes a location registration when it roams across location registration areas after a transition into the communication hold mode.

Abstract: A solid functional material comprises a functional agent such as a cleaning composition, a sanitizing agent, a rinse agent, etc. in a solid block format. The solid block is formed by a binding agent that forms the active ingredients into a solid block. The binding agent comprises a phosphonate or amino acetate sequestrant, a carbonate salt and water in an E-Form hydrate. These materials at a specific mole ratio form a novel binding agent that can form functional materials into a solid matrix form.

Abstract: A pressure flushing system for use in a toilet tank includes a housing with a water inlet conduit, an air and water inlet assembly connected to the conduit and to the housing, and a water outlet for the housing. There is a flush valve within the housing for controlling flow of water from the inlet to the housing outlet. The air and water inlet assembly includes a chamber, with a water inlet connected to the chamber, and an outlet connected to the chamber. There is an air inlet accessible to air at atmospheric pressure and a passage between the air inlet and the chamber. A check valve is located in the passage, with the check valve opening in response to a venturi effect caused by water flow through the chamber to draw air into the chamber to mix with water flowing through the chamber and to the outlet. The check valve includes an elastomeric sleeve positioned within the passage and having normally closed flexible lips extending toward the chamber. The lips open to permit the passage of air into the chamber to mix with the water therein when there is a pressure in the chamber less than atmospheric.

Abstract: The invention relates to a method and a device for avoiding interruptions in voice transmission in a cellular communication system. Voice data are thereby divided into segments, and the segments are associated with transmission quanta, so-called bursts. A number of segments is coded in a first transmission mode and is made available for transmission. Said first transmission mode is, for instance, for a transmission at full rate.  Additional segments, which follow, are subsequently coded in a second tramission mode and am made available for transmission. The second transmission mode is, for instance, for transmission at half rate.  Through the change from a first transmission mode to a second transmission mode, parts of the associated transmission quanta remain unused by applying the so-called interleaving. Said unused transmission quanta are used for performing additional functions, such as initiating a hand-over or FACCH signaling.
