Abstract: A wireless communication network comprising: (1) a plurality of mobile devices each configured to receive a beacon being broadcasted within the network and determine based on information transmitted within the beacon whether the mobile device is supported within the network; and (2) one or more access devices configured to broadcast the beacon within the network. Each of the mobile devices has a transmitting mechanism for communicating with the one or more access device. However, only those mobile devices that are supported by the network respond to the receipt of the beacon. Thus, no transmission occurs from the mobile devices until the device is identified as being supported by the network. These mobile devices instantiating a communication path with the one or more access devices and request an authentication from the one or more access devices. In this manner, a handshake mechanism is established between the access devices and the mobile devices that are supported by the network.

Abstract: A zone-based behavior service is supported by a small area wireless transmitter to communicate behaviors, encoded as attribute-value pairs, to wireless devices within the service area of the small area transmitter. In response to entering the service area and discovering the zone-based behavior service, operation of a wireless communications device is automatically customized to conform to the specified behaviors according to corresponding user preferences. For example, audible ring tones are automatically disabled when proscribed by the zone-based behavior service and such proscription is accepted by the user in previously defined attribute options, but automatic re-routing of incoming calls suggested by the behavior service may be rejected by the user or require manual acceptance from the user. Upon leaving the service area of the small area transmitter, the wireless communications device automatically restores prior operational parameters.

Abstract: To reduce change on a cellular network side required at the time of utilizing a cellular network by way of an IP network. A radio terminal 110 puts a location registration message for a cellular network 100 on an IP packet, and sends the message to an access point 102. This IP packet is transferred to a control proxy server 131. The control proxy server 131 stores a correspondence between identification information on a radio terminal and an IP address based on a location registration request. If necessary, the location registration request is converted into the location registration message in compliance with a standard of the cellular network 100. The location registration message is transferred to an MSC/VLR 121 via a gateway 130. As the gateway 130 looks like an ordinary base station to the MSC/VLR 121 and an ordinary location registration message is usable, any change on the cellular network side is not necessary.

Abstract: In a digital cordless telephone system, a different speech coding scheme is used in the audio path from the base unit to its remote handset than that which is used in the audio path in the opposite direction from the remote handset to the base unit. It is found that this unbalanced coding scheme optimizes overall system cost and performance. In particular, two different types, quality and/or bit rates of speech encoders are implemented in opposite directions of the same full-duplex audio path, providing an unbalanced coding in a digital cordless telephone. Implementation of different types of speech encoders in a common full duplex path optimizes system cost and performance. It is recognized by the invention that the communications link in a first direction from a base unit to its remote handset in a digital cordless telephone system potentially requires better codec and audio performance than the communications link in the opposite direction from the remote handset to base unit.

Abstract: Apparatus and a method for establishing a cellular mobile call. If no radio traffic (voice or data) channels are available for a calling Mobile Station (MS), then a test is made to determine the expected wait time before a channel becomes available. If the expected wait time is less than a first threshold, then the call request is queued. If a channel does not become available before a second time threshold, then the caller is notified that the call has been queued and is expected to be established in a short time. A control message is sent to the MS to trigger an indication of the queued status to the user. The indication may be one or more tones, a data display, or the playing of a pre-recorded announcement. If the expected wait time is more than the first threshold, the caller is given the opportunity to be called back when a radio channel becomes available. Advantageously, the number of failed calls because of unavailable traffic channels is reduced, and the caller's annoyance level is reduced.

Abstract: A cordless telephone set includes a base unit and a terminal unit. The base unit, which has detected by a terminal-unit detecting circuit that the terminal unit is placed thereon, awaits an identification number of the terminal unit to be transmitted from the terminal unit. The base unit receives the identification number of the terminal unit via an antenna and a transmitting-receiving unit.

If the determination result is negative, the identification number is added to the list, thus updating the terminal unit identification number list. Next, the base unit transmits its identification number to the terminal unit. Likewise, the terminal unit updates a base unit identification number list.
