    摘要: A radio (100) transmits and receives encrypted signals having unencrypted key identifiers, allowing other radios having the corresponding key identifiers and encryption keys to communicate with radio (100). Prior to transmitting an encrypted message, radio (100) selects a unique key identifier automatically and uses the corresponding encryption key to encrypt the message that will be transmitted. Radio (100) transmits the key identifier in an unencrypted format with the encrypted message in order to allow other radios to determine the encryption key used in encrypting the message. When receiving an encrypted message, radio (100) uses the predetermined process stored in the radio (100) to properly select the proper encryption key for use in decrypting the incoming message.

    摘要: A trunked communication system (400) transmits and receives encrypted signals over the system control channel (402). The trunked system (b 400) includes a plurality of radios (300) which can communicate with the communication system via control channel (402). By using control information signals and system information signals radios (300) can determine if it they are capable of decrypting the encrypted control information signals sent over the control channel (402). This is done by first determining if the encryption identification field found in the unencrypted system information signal matches an encryption identification field found in radio (300). If a match is found between the radio's encryption identification and the encryption identification field in the system identification signal radio (300) loads the encryption into the encryption circuitry in order to successfully decrypt the control information signals.

    摘要: A processing system comprises one or more processor devices and other system components coupled to a stacked memory device having a set of stacked memory layers and a set of one or more logic layers. The set of logic layers implements a metadata manager that offloads metadata management from the other system components. The set of logic layers also includes a memory interface coupled to memory cell circuitry implemented in the set of stacked memory layers and coupleable to the devices external to the stacked memory device. The memory interface operates to perform memory accesses for the external devices and for the metadata manager. By virtue of the metadata manager's tight integration with the stacked memory layers, the metadata manager may perform certain memory-intensive metadata management operations more efficiently than could be performed by the external devices.

    摘要: A method and apparatus for obtaining overhead information by a mobile is provided herein. During operation, the mobile will be communicating with a first system on an active data channel. The mobile node will be able to measure pilot PN phase and amplitude for a second system that is a potential candidate to handoff and will have that information available. The data channel of the active service is used to query a proxy server that provides overhead information for the second base station. More particularly, when PN phase and amplitude information is provided to the proxy server, the proxy server will identify the base station and provide the overhead information needed to associate with the second base station.

    摘要: A processing system comprises one or more processor devices and other system components coupled to a stacked memory device having a set of stacked memory layers and a set of one or more logic layers. The set of logic layers implements a helper processor that executes instructions to perform tasks in response to a task request from the processor devices or otherwise on behalf of the other processor devices. The set of logic layers also includes a memory interface coupled to memory cell circuitry implemented in the set of stacked memory layers and coupleable to the processor devices. The memory interface operates to perform memory accesses for the processor devices and for the helper processor. By virtue of the helper processor's tight integration with the stacked memory layers, the helper processor may perform certain memory-intensive operations more efficiently than could be performed by the external processor devices.
