Abstract: A method for sharing a common receiver (850) between a cellular telephone (870) and a pager (880) such that selectively tuning the receiver to receive cellular telephone system frequencies (C) and pager system frequencies (P) allows simultaneous operation as a cellular telephone and pager during periods when both devices are in sleep mode. The method includes prioritizing operation of one of the devices (320-360), anticipating the occurrence of both cellular system paging channel transmission (410, 510, 640) and pager system paging channel transmission (550, 610, 710), and tuning the common receiver to the appropriate frequency band (430, 530, 560, 620, 650, 730).

Abstract: Exemplary embodiments of the present invention describe terminal position location methods and systems. Relative powers of nearby spot beams which are generated by array antennas are determined. For example, powers from six neighboring spot beams relative a center spot beam within which a mobile station is currently operating, can be measured relative to the power of the center spot beam. Using information from these measurements, the mobile stations position can be determined using, for example, an exponential model of the spot beam pattern.

Abstract: A contact assembly provides a reliable contact between a battery pack and an electronic device. The assembly includes a plurality of contact members and an insulator molded to the contact members. The plurality of contact members preferably include a positive contact member and a negative contact member each having a weldable surface and a selectively plated surface. The weldable surfaces are welded to the positive and negative terminals of the battery pack, respectively. The selectively plated surfaces are preferably plated with gold to ensure a good connection between the device and the battery pack. The insulator serves to fix the contact members relative to each other. In addition, the insulator facilitates minimization of the battery pack size by enabling the contacts to be placed very close to each other.

Abstract: Methods and apparatus for preventing tampering with memory in an electronic device, such as a cellular telephone, are disclosed. An electronic device having a memory and a processing means contains logic that is used to perform a one-way hash calculation on the device's memory contents whereby an audit hash value, or signature, of such contents is derived. The audit hash value si compared to an authenticated valid hash value derived from authentic memory contents. A difference between the audit and valid hash values can be indicative of memory tampering. In accordance with another aspect of the invention, electronic device memory contents can be updated by a data transfer device that is authenticated before being permitted access to the memory contents. Data transfer device authentication involves the use of a public/private key encryption scheme. When the data transfer device interfaces with an electronic device and requests memory access, a process to authenticate the data transfer device is initiated.

Abstract: A multi-mode mobile station receives a subscriber identity module (SIM) card storing at least certain communications standard required subscription information that is common to a plurality of types of cellular telecommunications systems. The mobile station also includes an internal memory for storing communications standard required subscription information unique to each type of cellular telecommunications systems for which mobile station operations are supported. If a certain type of cellular telecommunications system is selected for mobile station operation, and the inserted SIM card fails to include the necessary communications standard required subscription information for that type of system, the common information is extracted from the SIM card and used in combination with the internal memory stored unique information specific to the selected type of system in effectuating mobile station operation.

Abstract: A vehicular repeater system communicates with a portable mobile radio using the same RF communication band and digital trunking protocol that it communicates with a base site. The repeater station may employ an operational radio within a vehicle which communicates with the base site. A separate repeater radio module is connected to the operational radio, preferably through hardwired links. The separate repeater radio module includes a transmitting section which receives messages from the base site through the operational radio, and forwards these messages through a passive RF interface to a portable radio. The separate repeater also includes a receiving section which receives messages from the portable radio, and forwards these messages through the operational radio to the base site. Additionally, the receiver section may include a padded receiving section with low power amplification and additional receiver attenuation for monitoring other nearby vehicular repeater systems for potential interference prior to allowing its own vehicular repeater to become active.
