Abstract: A network infrastructure element (300) can be configured to, upon determining (101) that an end-user platform (305) seeks to download an executable program, execute (103) the program to develop a corresponding model that represents corresponding operating system call-based behavior. The network infrastructure element can then use (104) this model to vet the operating system call-based behavior of the program with respect to end-user platform policies. When the operating system call-based behavior vets acceptably with respect to these policies, the end-user platform can then be permitted to download (106) the executable program. If desired, the network infrastructure element can provide (107) the model to the end-user platform to permit vetting of the modeled behavior with respect to locally-maintained policies. The model provided to the end-user platform can comprise a size-reduced sliced model.

Abstract: Embodiments of the invention generally provide a method and apparatus for enabling digital rights management in file transfers. One embodiment of a method for transferring digital content from a first user to a second user, includes transferring ownership of an instance of the digital content to the second user, where the instance of the digital content resides on a first device belonging to the first user. Copies of the digital content are then deleted from one or more additional devices belonging to the first user (including at least one offline device).

Abstract: Disclosed is a method, system and apparatus for transferring protected data (404) having an authorizing entity's outer encryption layer (408) and having a user-fixed inner encryption layer (406) from a first electronic device having a first unique, unalterable identifier to a second electronic device having a second unique, unalterable identifier.

Abstract: A mobile station (106) of a wireless communication system (100) detects (502) a predetermined user command applied to a user interface (308) of the mobile station. In response, the mobile station transmits (504), to a fixed portion (110) of the wireless communication system, a message including a request for local information and services. The fixed portion receives (506) the message, and, in response, determines (508) the location at which the mobile station is positioned. The fixed portion then generates (510) A the local information and services custom-tailored to a predetermined area around the location, and sends (512) the local information and services to the mobile station.

Abstract: A selective call receiver (106) has a frequency synthesizer (708) for scanning a plurality of frequencies to determine a control channel to receive a signal and a receiver (704) for receiving the signal representative of an available frequency associated with a geographic region. The signal includes a channel identifier (404), a frequency assignment (406) and an active channel indicator (408). A processor (712) associates the channel identifier (404) with the frequency assignment (406) in response to the active channel indicator (408) indicating an available frequency of the geographic region and a memory (720) stores channel identifiers (404) associated with frequency assignments (406) designating available frequencies (408).

Abstract: A system and method are shown for providing a fully synchronized two-way communication network having a number of transmission stations (10) and selective call receiving devices (27). Each transmission station (10) stores station identifying information and an updatable synchronization priority indicator. Periodically, each station (10) transmits a timing message that includes the station's identifying information, priority indicator, and information relating to the timing of the station's frame clock (45). When a given station receives a timing message transmitted from another station, it determines whether the other station is a direct upstream station thereof. The given station is responsive to a timing message from its direct upstream station for adjusting its frame clock (45) based upon the timing information contained in the message received from the direct upstream station. The given station thereby synchronizes itself with its direct upstream station.

Abstract: A technique for communicating global information in a radio communication system (100) in which a radio (106) is in a receive state during a first predetermined period of each of a plurality of transmission cycles (320) includes decoding a global event indicator (344) in a system information portion (331) of the first predetermined period of a first transmission cycle (320), setting the radio (106) to the receive state during a second predetermined period of a second transmission cycle (320), receiving the second predetermined period, decoding global event information in the second predetermined period, and processing the global event information. The second transmission cycle (320) is subsequent to the first transmission cycle (320).

Abstract: A portable radio device (106) has a first operational mode and a second operational mode, and includes a receiver (314), a controller (315), and a mode control device (350). The receiver (314) receives an indexed information message. The controller (315) stores an authorized information field list and is coupled to the receiver (314). The controller (315) decodes the indexed information message, generates an index portion of the decoded indexed information message, and generates a mode control schedule determined by the index portion and the authorized information field list. The mode control device (350) is coupled to the controller (315) for controlling the first and second modes of the portable radio device according to the mode control schedule.

Abstract: A method and apparatus for closed loop frequency control in a two-way radio communication system (100) include a base communication unit (104) and a portable communication unit (108) having a portable-to-base initiation channel (202) assigned to a predetermined frequency. A signal is transmitted (502) from the portable communication unit (108) to the base communication unit (104) on an initiation frequency of approximately the predetermined frequency. The base communication unit (104) determines (506) from the signal a frequency correction factor (326) for recalibrating the initiation frequency in accordance with the predetermined frequency. The frequency correction factor (326) is communicated (512) to the portable communication unit (108), and the portable communication unit (108) recalibrates (516) the initiation frequency in response.

Abstract: A method and apparatus for reliably delivering information service messages (300) from a central terminal (106) to a communication receiver (118) in a wireless message communication system (100). The communication receiver (118) receives information service messages including an information group identifier and data updates corresponding thereto. The communication receiver (118) receives disable messages (400) including an expiration time. The communication receiver (118) decodes received data updates (306) when the information group identifier (226) is determined as enabled. It does not decode received data updates (306) when the information group identifier (220) is determined as disabled (222). The communication receiver (118) determines enabled status as a default condition, and determines disabled status when a disable message (400) was received.

Abstract: An apparatus (100) couples first and second electronic devices (206, 202), the first electronic device (206) having an optical communications port (208) and the second electronic device (202) having an electrical communications port (204). The apparatus (100) includes an electrical interface (102) functionally compatible with the electrical communications port (204), and an optical interface (107) functionally compatible with the optical communications port (208) and electrically coupled to the electrical interface (102) for communicating with the electrical interface (102). The electrical interface (102) and the optical interface (107) provide communications between the electrical communications port (204) and the optical communications port (208) when the electrical interface (102) is electrically coupled to the electrical communications port (204), and the optical interface (107) is optically coupled to the optical communications port (208).

Abstract: A selective call receiver (111) has a first mask (134A) stored within the selective call receiver (111) indicative of a first period of reception for receiving a transmitted communication signal (99) having a plurality of packets (100). Each of the transmitted packet (100) has message information (110). An identifier (106) identifies the packet (100). The control signal (108) is representative of a second mask (134B) indicative of a second period of reception. The second mask is compared with the first mask for determining the second period of reception of the selective call receiver (111). A correspondence between the first and second masks determines whether to change the first period of reception of the selective call receiver (111) for receiving at least one additional packet.

Abstract: A selective call receiver system includes a plurality of base sites capable of simultaneous operation. Each base site includes a transmitter and a base receiver capable of measuring the signal strength of a received signal. A controller coupled to the plurality of base sites, forwards an address to the plurality of base sites. The transmitters thereafter, simultaneously transmit the address to at least one of a plurality of selective call receivers having acknowledge-back capability. At least one of the plurality of base receivers receive an acknowledge-back signal from the at least one of the selective call receivers responding to the transmitted address. The signal strength of the acknowledge-back signal is detected by the plurality of base receivers receiving the acknowledge-back signal.

Abstract: In a battery powered selective call receiver receiving a synchronous signal, a battery saving method extends battery life by optimizing the amount of time the receiver circuit is activated when searching for the signal after previously acquiring synchronization. The battery saving method allows for turning the selective call receiver on without activating the receiver circuit. The receiver circuit is activated at a time later than the energization of the selective call receiver, where the time of activation of the receiver circuit is determined in response to the time passed since synchronization was last acquired and the system signal stability.

Abstract: An acknowledge-back pager receives an address signal positioned within a group of address signals. Following reception of the address signal, first and second acknowledge signals are transmitted as determined at least in part by the received address signal's position in the group of address signals, such that, the first and second acknowledge signals are not simultaneously transmitted.
