Abstract: A mobile communication subscriber apparatus such as a portable phone allows its user to make prompt contact with someone who places a call to a specific phone served as a local base station to the subscriber apparatus. The mobile communication subscriber apparatus is arranged to register its position to a base station when it is used at an external mode. This subscriber apparatus provides a mechanism for transmitting a control signal for indicating change of the settings of an answering function of the local base station.

Abstract: This invention is a method of identifying and validating a cellular telephone for activation and for subsequent servicing after activation. A cellular service provider (CSP) (401) specifies an International Mobile Subscriber Identity (IMSI) number for a Subscriber Identity Module (SIM), generates a Mobile Station Integrated Services Digital Network (MSISDN) telephone number, associates the MSISDN with the IMSI in a table, and orders a SIM from a SIM manufacturer (403). The SIM manufacturer manufacturers the SIM, programs the IMSI into the SIM, places a SIM serial number on the SIM, sends the CSP information associating the SIM serial number with the IMSI, and sends the SIM to a Distribution Center (405). A hardware vendor (407) sends a handset and an International Mobile Equipment Identity (IMEI) number for the handset to the Distribution Center.

Abstract: A wireless user terminal (10), such as a cellular telephone, includes a transceiver (14, 16) for conducting bidirectional RF communications with a communications network (32) and a data processor (18b) for controlling the operation of the terminal. The terminal further includes (a) a first memory capable of storing a data processor program; (b) a second memory capable of storing a data processor program; (c) a memory device or register for storing a flag for indicating which of the first and second memories is a currently Active memory, that stores a currently active data processor program, and which of the first and second memories is a currently Idle memory; and (d) circuitry for receiving another data processor program from the communications network and for storing the received another data processor program into the Idle memory. The circuitry operates while the data processor executes the data processor program stored in the Active memory.

Abstract: A cellular telephone assembly includes a front shell having a mounting pin and a locating pin, and having a plurality of keyholes, a base shell having a mounting pin and a locating pin, and a light guide formed of substantially translucent material and having a substantially planar shape, the light guide having a mounting boss with a hole therethrough, the centering pins of the front shell and base shell being insertable in the hole from opposite side thereof and frictionally engageable therein, the light guide further having a locating hole, the locating pins of the front shell and base shell being insertable in the locating hole. The mounting pins and locating pins of the front and base shells cooperate with the mounting boss and locating hole of the light guide for ready alignment and fastening of the components. The invention includes a method for assembling the components, which allows the formation of convenient sub-assemblies of the components before final assembly.

Abstract: A portable radiotelephone device (100) comprises a radio housing (114) having radiotelephone circuitry (1102), a battery housing (110) having a battery (1104) and an accessory housing (1100) having accessory circuitry (1106). A first latch mechanism (116) secures the battery housing (1100) to the radio housing (114) to permit the battery (1104) to power the radiotelephone circuitry (1102) via a first pair of conductive power contacts (1108, 1110). A second latch mechanism (118) secures the accessory housing (1100) to the battery housing (110) to permit the battery (1104) to power the accessory circuitry (1106) via a second pair of conductive power contacts (112, 1112).

Abstract: Portable wireless telephone handset with a flap movable upon a housing. In a first position the flap is close to a speaker to enable the flap to be disposed near to a user's ear for the user to receive personal low volume sound from the speaker. In a second position, the flap is further from the speaker to detract from use of the speaker near to the user's ear. In the second position of the flap, the speaker operates in loudspeaker mode. A switch is provided to change the speaker between loudspeaker and low volume sound mode, the switch operation being dependent upon flap position.

Abstract: A combined landline Advanced Intelligent Network (AIN) and Cellular Digital Packet Data (CDPD) system provides the capability of call feature selection using control signals generated by a mobile subscriber. The calling features are specified by the control signals which are sent within the CDPD system from the subscriber station to a CDPD controller or switching entity. Protocol translation takes place so that the control signals from the subscriber station are placed in a form suitable for the CCIS normally used in an AIN. These signals are transferred to convenient AIN switching or control entity and sent to an ISCP where the request for calling features are evaluated and instructions given to other elements of the AIN to provide the requested calling features.

Abstract: A cellular telephone network including a plurality of service areas each served by a different mobile switching center wherein messages are transmitted between mobile switching centers, accounting for instances of inter-service area handoff of a mobile subscriber cellular call, to identify the public safety answering point (PSAP) system to be utilized in answering an emergency telephone call from the mobile subscriber. When multiple inter-service area handoffs have occurred, the PSAP identification message is sent from the serving mobile switching center to the anchor mobile switching center to allow for the identification of the appropriate PSAP. This message could be relayed through one or more intermediate tandem mobile switching centers.
