Abstract: A method of operating a mobile telephone within a geographical area having overlapping coverage from a first, GSM, network and a second, UMTS, network, where said GSM network is the home network (HPLMN) of the mobile communication device and said GSM and UMTS networks provide respective first and second sets of services in said geographical area. The method comprises registering the telephone with the GSM network when a service of said first set is requested and registering the device with the UMTS network when a service of said second set, but not of said first set, is requested. The method provides the mobile telephone with a roaming for service function.

Abstract: A communication system (100) that includes base stations (103-109) comprising selection circuitry (207) is provided herein. The determination of a call anchoring base station (base station performing Code Division Multiple Access (CDMA) frame selection) is made based on the base station with a lowest mean work load. During communication with a remote unit (113), frames received by non-call anchoring base stations (105, 107) are backhauled to a switch (101). The switch (101) then sidehauls the frames to the call anchoring base station (103), where selection and call processing functions for the particular call takes place.

Abstract: A cellular system includes wide band digital signal processing at a central office that is connected to one or more cellular sites by optical fiber cables. Data signals are exchanged between the cell sites and the central office using intensity modulated optical data signals. Control of call supervision and handling is consolidated in the central office to enable dynamic variation of wireless service reception and transmission capabilities at a cell site in response to changing demands for wireless service. Each antenna at a cell site may receive and transmit an assigned RF bandwidth using any frequency within that band. The central office processes the entire received spectrum for controlling detection and transmitting range, RF carrier frequency and transmit power level for an active channel link established between a cellular station and the system in a cell site.

Abstract: A portable telephone set is provided with a remote control button for remotely controlling the base station telephone set by operating the button. If the portable telephone set is out of the service area of the base station set when the remote control button is operated, the portable telephone set calls the base station set by using the telephone numbers of the base station set stored in the RAM of the portable telephone set to connect it to the base station set by way of a line and thereafter transmits a remote control signal for the operated remote control button to the base station set. If the portable telephone set receives control information from a radio base station as it enters the service area of the radio base station from outside the service area, the speaker of the portable telephone set sounds to notify the user of the situation.

Abstract: When a power failure occurs, a control unit 107 of a main apparatus 101 acquires the outside line 102a through an outside line I/F unit 102 and transmits a signal for requesting terminating transfer and a signal for designating a transfer destination to a public network 108 while receiving power from a backup power supply 106M. After this terminating transfer is requested, and an incoming call to the telephone number of an outside line 102a is received, the public network 108 calls the transfer destination designated for terminating transfer. If the telephone number for calling a radio telephone set 109 from a public base station 113 is designated as this transfer destination, the public base station 113 calls the radio telephone set 109 in a terminating transfer operation.

Abstract: Outputs of A/D converters 110, 111, and 112 are input to correlation devices 117, 118, and 119.

Abstract: Radio equipment is made up of a portable telephone and a charger for charging it. Whether or not the telephone is set on the charger is determined, when a call incoming occurs while the telephone is set on the charger, the telephone alerts the user of the telephone to the call incoming via a call incoming reporter selected beforehand. If the call incoming reporter selected beforehand uses vibration, a vibration detector included in the charger detects the vibration of the telephone. Subsequently, an alert tone is output via aa speaker included in the charger. When the user hearing the alert tone picks up the telephone from the charger, the alert tone output from the speaker ends.

Abstract: A terminal coupled to an intelligent telecommunication network may invoke dynamically modifiable subscriber services by transmitting information to a switch to which script files, each containing programming script needed to initiate a calling feature or other advanced subscriber service and a criteria statement used for triggering execution of the programming script, were downloaded thereto from a home location register where the script files may be added, deleted or otherwise modified by a system administrator. A program execution module residing at the switch compares the received information to the criteria statement for each script file downloaded thereto and executes the programming script of the script file having a criteria statement which matches the received string of digits. In wireless systems, the script files are downloaded to an MSC whenever a roaming terminal registers therewith.

Abstract: A method and apparatus for a handset are provided to select a channel for monitoring a system operating under a cellular radio telephone protocol supported by repetitive cellular radio systems. A base station transmits a signal packet having time slots and fields, which are recognizable by the handset. There is a selection of a carrier of a channel to scan in order to detect the packet. Upon finding a specified data field in the packet, there is a checking of a primary access right identity (PARI). Thereafter, the system may be found in order for the handset to lock onto the system, and, in the event that the system is not found, the procedure continues with a second pass which begins with a recording of received signal strength and secondary access right identity (SARI) information. In the second pass, there is again a selection of a carrier for scanning, this being obtained by use of information of the first pass.

The controlling unit produces and supplies, at every predetermined time interval, the first and second matching switching control signals to the switching circuit, respectively, to make a memory device memorize, as first and second level signals having first and second level values, detected level signals from a level detecting circuit when the switching circuit connects the antenna to the first and second impedance matching circuits, respectively, when the detected level value from the level detecting circuit is smaller than one of the first and second level values that corresponds to the second greatest level value in the first and second level values, and when the controlling unit is supplied with a human body contact discriminating signal from a human body contact discriminating circuit.

Abstract: The universal dictation input apparatus and method disclosed employs multiple wireless dictation devices (“WDD”) and base stations each of which include a 900 MHz radio for communicating with one another over selected radio frequency (“RF”) channel pairs to conduct dictation sessions on centralized dictation systems (“CDSs”). Each base station is uniquely assigned a single channel pair. The WDDs are programmed with code representing the exclusive channels of a select number of base stations. When a user takes a WDD off-hook, a WDD sequentially and cyclically scans for carrier transmitted by authorized base stations until an idle base station is identified and linked to over the authorized channel. The user of a WDD must be authorized to conduct dictation sessions on one or more CDSs. To this end the WDDs includes a dialing address keypad to address authorized CDSs. The CDSs are third party systems addressed from a WDD by DTMF dialing digits.

Each selected identity may be allocated a separate directory number or all identities may be allocated a single number.

Abstract: The result of detection performed by a receiving electric-field level detection circuit 8 and the result of detection performed by an automatic gain setting circuit 9 are fed back to a timing signal generation circuit 10 which controls a pre-heat time of a selective calling/receiving device. As a result, the pre-heat time can be changed according to the state of propagation of radio waves, and hence the life of battery of the calling/receiving device can be increased.
