A handoff method of wireless LAN comprises the steps of: 1) immediately starting by a mobile terminal to count time from a time point of entering the wireless LAN or building the new association, that is, when building association with a certain access point; 2) always tracking a signal-to-noise ratio (SNR) of the old access point by the mobile terminal, and once the mobile terminal starts getting weak, starting to search for a near access point and making a preparation for handoff, and issuing a probe request signal to a new access point, and always responding to a probe response message by the new access point after receiving the probe request signal; and 3) judging by the mobile terminal whether or not to associate the new access point according to a signal strength and an association time of each of the access points, and if a judging result is yes, issuing the reassociation request signal to the new access point. Accordingly, the new access point issues a reassociation response message to build the new association.

Method and apparatus for reducing a shrinkage amount of a rubber member (51) which is comprised of a rubber (3) extruded from an extruder (1). At least one vibrator unit (10a, 10b) applies vibration to the extruded rubber (3) so as to increase the shrinkage speed of the extruded rubber (3) and cause a sufficient advance shrinkage of the extruded rubber within the extrusion train (1), thereby reducing a posterior shrinkage amount of the rubber member (51). An adjustable thermoregulator (30) maintains the extruded rubber (3) at a controlled temperature during application of vibration.

A communication system which includes plural radio systems, and which connects to a terminal apparatus corresponding to the plural radio systems, comprising: access points for the each radio system; gateways; an authentication apparatus; and a home agent. The authentication apparatus being shared by the plural radio systems: assigns an IP address to the terminal apparatus in a radio system which is initially connected among the plural radio systems according to an IP address assignment request from the terminal; judges whether an IP address assignment request for a radio system to be subsequently connected is from the same terminal apparatus by using an unique identifier of the terminal; and assigns the IP address assigned in the initially connected radio system to the terminal apparatus in the radio system to be subsequently connected in a case where the assignment request is determined to be from the same terminal apparatus.

The problem of the invention is to provide a resin composite electrolytic copper foil having further improved heat resistance and improved plate adhesion strength when plated after desmear treatment in the work process of an additive method. The solution is to form a roughened surface having a plurality of minute projections, a surface roughness (Rz) within a range of 1.0 μm to 3.0 μm and a lightness value of not more than 30 on one surface of an electrolytic copper foil, and form a layer of a resin composition containing a block copolymerized polyimide resin having a structure that imide oligomers of a first structural unit and a second structural unit are bonded alternately and repeatedly on the roughened surface.
摘要:
To prevent a hung-up of communications due to changes in a radio wave condition resulting from frequent displacement of the terminals and changes in a number of the terminals, and to realize switching of the radio systems adapting to the radio condition. A radio communication system comprising: a base station for providing a plurality of radio systems, and terminals for communicating with the base station through the plurality of radio systems. The base station decides a priority of the radio system on which the each terminal will communicate thereafter and transmits paging signals of one of the plurality of radio systems which includes information on the decided priority to the each terminal.

When receiving a session control signal from a terminal (12), a terminal accommodating apparatus (11) disposed for each line adds the identifier of an access line to the received session control signal and then transmits the resultant signal to a session control server (3). The session control server (3) transmits the access line identifier to a QoS control server (5). The QoS control server (5) performs a QoS control based on a band requested in the session associated with the identifier of the same access line.
摘要:
In order to solve the problem in that information relating to a specific purpose can be saved in the internal memory of a mobile apparatus on which a permanent memory is mounted while information relating to other purpose cannot be saved in the internal memory of the apparatus, the purpose of each telephone call is distinguished by sending a non-telephone type notice before transferring the call and thus the user can determine whether the call should be saved or not.
摘要:
The invention provides a method for selecting a communication IP address whereby traffic of a network can be reduced and a session with the partner of communication can be maintained even when the mobile node has moved. The method prescribes provision of means for judging a state of a foreign network to which the mobile node is connected, and means of monitoring an IP address that an application having been started by the mobile node is using for communication, and enables selection of the mobile IP address so that the mobile node can maintain the session surely even in a visited foreign network.

Oil or fat compositions contain the following ingredients: (A) an oil or fat containing from 60 to 100% by weight of diglyceride, by 100 parts by weight of the oil or fat composition, the diglyceride further comprising fatty acids, wherein the amount of fatty acids that are unsaturated is from 80 to 100 wt. %, by 100 parts by weight of the diglyceride; (B) from 0.001 to 1 % by weight of ingredient (A) of a carboxylic acid selected from C2-8 hydroxycarboxylic acids, dicarboxylic acids and tricarboxylic acids, and salts derivatives thereof, and mixtures thereof; (C) from 0.001 to 5 % by weight of ingredient (A) of an antioxidant; and (D) from 0.05 to 4.7 % by weight of ingredient (A) of a plant sterol. Each of these preferred oil or fat compositions has a high diglyceride content having excellent health-promoting functions, and even in cold temperature areas or high-humidity areas, has improved external appearance, is good in work efficiency during cooking and also in the flavor and texture of cooked foods. Packaged edible oils or fats are also disclosed.
