Abstract: Techniques are described for verifying a status of a set of paths through a computer network for two or more connectivity protocols. For example, a node uses a first connectivity protocol to concurrently learn information that will cause packets conforming to the first connectivity protocol and packet conforming to a second connectivity protocol to traverse a set of paths through a computer network. After learning this information, the node may verify a status of each of the paths using the first connectivity protocol. In addition, the node may verify a status of each of the paths using the second connectivity protocol. By verifying the status of the paths using both the first and the second connectivity protocols, the node may be able to quickly and accurately determine whether a path has failed.

The device determines that the LTE device has the bearer established, and provides a modify bearer request, with the second parameters, to the wireless network in order to modify the bearer with the LTE device to a second data rate.

Abstract: Techniques for performing analysis of a cellular telephone signaling environment in the presence of interferers. The techniques do the analysis by employing a receiver to listen to the cellular environment during holes in the interference. The holes have a timing which differs from that used by the cellular telephone signaling environment and will thus over time overlap with structures of interest in the cellular telephone environment. The holes may be smaller than the structure of interest. The signals which the receiver hears in the holes are analyzed and combined to reproduce the structure. The combination may involve statistical methods and weighted decoding. The analysis obtains information which permits surgical attacks on individual wireless devices which are in the traffic state. Example applications of the techniques are given for the GSM and CDMA cellular telephone standards.

Abstract: Data streams stored in buffers are modulated by modulation sections. Multipliers multiply the signals output from the modulation sections by weights output from a weight control section. The signals output from the multipliers are added up by addition sections, subjected to radio transmission processing by transmission radio sections and sent through antennas. A buffer control section controls the buffers based on a retransmission count output from a retransmission count detection section. The weight control section outputs weights different from weights at the time of previous transmission to the multipliers every time data is retransmitted. This allows a diversity gain at the time of data retransmission to be increased even if a time variation of the propagation path environment for radio signals is slow.
