Abstract: Upon detection of a trigger, such as the exceeding of an error threshold or the direction of a user, a diagnostic link system enters a diagnostic information transmission mode. This diagnostic information transmission mode allows for two modems to exchange diagnostic and/or test information that may not otherwise be exchangeable during normal communication. The diagnostic information transmission mode is initiated by transmitting an initiate diagnostic link mode message to a receiving modem accompanied by a cyclic redundancy check (CRC). The receiving modem determines, based on the CRC, if a robust communications channel is present. If a robust communications channel is present, the two modems can initiate exchange of the diagnostic and/or test information. Otherwise, the transmission power of the transmitting modem is increased and the initiate diagnostic link mode message re-transmitted to the receiving modem until the CRC is determined to be correct.

Abstract: A first communication node (110) receives a stream of code blocks from a second communication node (120) over an acknowledged connection (131.). The first communication node processes the received code blocks in accordance with at least one transport format parameter, TFP, detects errors in received code blocks, and transmits an acknowledgment in respect of groups of code blocks indicating whether at least one error was detected in the group. A first subset of the code blocks of a group are transmitted (e.g., modulated and demodulated) in accordance with a first TFP value, and a remainder of the code blocks are transmitted in accordance with a second TFP value. Because the first and second TFP values are independent, it is possible either to shorten the necessary processing time in the first communication node or, in connection with a predictive acknowledgment mechanism, to make the receiving-side processing of code blocks that do not contribute to the value of the transmitted acknowledgment more robust.

Abstract: A security mechanism in a database management system enforces processing restrictions stored as metadata to control how different pieces of a multi-nodal application are allowed to access database data to provide data security. The security mechanism preferably checks the data security restrictions for security violations when an execution unit attempts to access the data to insure the nodal conditions are appropriate for access. When the security mechanism determines there is a security violation by a query from an execution unit based on the security restrictions, the security mechanism may send, delay or retry to maintain data security. Nodal conditions herein include time restrictions and relationships with other columns, rows or pieces of information. For example, multiple processing units may execute together, but the security mechanism would prohibit these processing units to access specific pieces of information at the same time through the use of metadata in the database.

Abstract: A system and method for testing multiple wireless data packet signal transceiver devices under test (DUTs) with dynamic signal interference compensation. Transmit data packets originating from other DUTs are monitored during receive signal testing of a selected DUT for concurrent occurrences of transmit and receive data packets. From this, it can be determined whether a failure to receive a responsive data packet, such as an acknowledgement, from the selected DUT is likely due to interference from a transmit data packet from another DUT being at least substantially concurrent with the receive data packet to which the selected DUT was expected to respond. If so, one or more receive data packets can be added to the receive signal sequence to extend the test and determine an accurate packet error rate (PER) without requiring a repeat of the full test.
