摘要： A method and system for location determination at a mobile communication device 102 is provided. The mobile communication device 102 includes a satellite positioning receiver 410. The mobile communication device 102 acquires a first location aiding parameter and a second location aiding parameter from a first Terrestrial Communication Network (TCN) 108 and a second TCN 110, respectively. Selection of the first TCN 108 and the second TCN 110 is based on the first and second location aiding parameters, respectively. The satellite positioning receiver 410 uses the first and second location aiding parameters to determine the location at the mobile communication device 102.

摘要： A mobile communication device (202) and peer mobile communication devices (204, 206) are capable of direct voice and data communication. The mobile communication device has a reference oscillator (104) which is used for generating operating frequencies, and is subject to frequency errors resulting from manufacturing tolerances, heat, and other error sources. The mobile communication device receives a frequency correction message (506) from a peer mobile communication device that has calibrated its reference oscillator. The frequency correction message contain offset information which is used by the mobile communication device to determine its offset (316) from a nominal frequency (302).

摘要： N redundant processors operating in functional lockstep synchronization for maintaining system integrity. Comparison and synchronization logic are connected between N processors in redundant configuration and peripheral devices. The comparison and synchronization logic act to insure that the redundant processors are performing the same read/write operations. Calculation or processing not requiring access to peripherals may take place in an asynchronous manner. Processors are halted from performing further operations until all appropriate read or write operations are synchronized. The processors are then allowed to proceed. An overall watchdog timer provides for detecting an error condition for non-responsive or lead responding processors.

摘要： An arbitrary repeating pattern detector (ARPD) detects short cycle patterns having a length of N or less, where N is an integer number. The ARPD obtains data symbols from a random number generator. ARPD may be implemented in a circuit or process which evaluates data symbols b.sub.1 -b.sub.2N. A mismatch detector compares symbols b.sub.I+J-1 with symbols b.sub.N+J for all combinations of I and J, where I and J are integer numbers in the range of 1-N, inclusive. For each value of I, an alternative detector determines whether at least one mismatch occurs at any value of J. If such a mismatch is detected, an alternative indication declares a mismatch at the corresponding value of I. A conjunction detector determines whether alternative indications for all values of I indicate mismatches. If a single match is found, a repeating pattern is declared.

摘要： A system (20) and method (50) of establishing a rapid push-to-send data exchange in a multi-wireless network environment can include a first wireless network (24 and 26) having a fast network channel to exchange an Internet Protocol (IP) address or other data, a second wireless network (23 and 27) operatively coupled to the first wireless network having a high bandwidth data channel to exchange data using the IP address in a wireless peer to peer data transfer, and a communication protocol. The first wireless network can be an iDEN network and the second wireless network can be a CDMA network. The communication protocol can relinquish (66) communication using the first wireless network once a dedicated data channel on the second wireless network is established. The communication protocol can also simultaneously transfer (56) voice traffic on the first network when the first network is exchanging the IP address.

摘要： Methods and apparatus are provided for secure communication techniques in a communication system. The system can include a first device which communicates with a second device over a channel. A security association can be established during a first session between the devices via an asymmetric key exchange. The security association comprises a Traffic Encryption Key (TEK) and a first state vector. The TEK comprises a shared, secret symmetric key. The security association is stored in each of the devices for use during a second session between the devices to expedite security association establishment during call set-up of the second session. The security association can be associated with the second device in the first device, and with the first device in the second device. An updated state vector can be generated at the first device. A second session can be established between the first device and the second device by using the TEKs from the first session and the updated state vector. The security association can be used to encrypt voice packets being sent from the first device to the second device. The security association and updated state vector can then be used to decrypt the encrypted voice packets received by the second device from the first device.

摘要： An encryption capable communication device (10) can include a transceiver (38 and 44) and a processor (12) coupled to the transceiver. The processor can be programmed to receive notification of a secure call alert indicative of a desire for secure communications between an alerting device and the encryption capable communication device serving as a recipient device and further cause the recipient device to switch (64) to a secure mode in response to receipt of the notification. The processor can be further programmed to initiate a key exchange (67) between the alerting device and the recipient device if needed and automatically respond (70) to the secure call alert by the recipient device in the secure mode when a user of the recipient device selectively responds to the secure call alert. The processor can also establish a symmetric traffic key during the key exchange using Automatic Public Key exchange techniques.
