Method, apparatus and computer readable medium for terminating and newly constructing a send routing information (SRI) message in mobile networks
An originating SMSC in Network A issues an SRI-SM towards the HLR of a recipient (User B in Network B). One of a number of N Platforms or Message Controllers (“MCOs”) intercepts the SRI-SM. Instead of passing on the SRI-SM, the MCO terminates it and performs a full decode of all fields, specifically extracting the recipient MSISDN from it. The MCO then constructs a new SRI-SM for the same MSISDN, but forcing the new request to ask for all available data, including, but not necessarily limited to visited-MSC address, SGSN address and IP-SM-GW address. When a response is received the MCO generates a fresh query response for the originating SMSC instead of merely routing on the response which it receives. If the MCO is programmed to provide a false address for smart services it incorporates the false address in the query response which it generates. |

Universal asymmetry compensation for packet timing protocols
The notion of a “PTP aware” path is one current proposed approach to reduce asymmetry effects. In a fully PTP aware path there is the notion of on-path support mechanisms such as boundary clocks and transparent clocks at every switching or routing node. However, on-path support methods only address time-transfer errors introduced inside network elements and any asymmetry in the transmission medium, such as, for example, the fiber strands for the two directions of transmission, cannot be compensated for by on-path support mechanisms. Furthermore, in a real operational network, which may traverse different operational domains administered by different entities, full on-path support is a difficult challenge. In certain managed network scenarios full on-path support can be contemplated. Nevertheless, the universal asymmetry compensation method described herein mitigates the asymmetry in a network path, without requiring on-path support mechanisms such as transparent clocks and boundary clocks. |

Training-based channel estimation for multiple-antennas
The burden of designing multiple training sequences for systems having multiple transmit antennas, is drastically reduced by employing a single sequence from which the necessary multiple sequences are developed. The single sequence is selected to create sequences that have an impulse-like autocorrelation function and zero cross correlations. A sequence of any desired length Nt can be realized for an arbitrary number of channel taps, L. The created sequences can be restricted to a standard constellation (that is used in transmitting information symbols) so that a common constellation mapper is used for both the information signals and the training sequence. In some applications a training sequence may be selected so that it is encoded with the same encoder that is used for encoding information symbols. Both block and trellis coding is possible in embodiments that employ this approach. |

Trace canceller with equalizer adjusted for trace length driving variable-gain amplifier with automatic gain control loop
Distortions of both amplitude and phase along a transmission line are compensated for by a trace canceller inserted between a transmitter and a receiver. The trace canceller has an equalizer that compensates for a trace length between the transmitter and the trace canceller. A variable gain amplifier between the equalizer and an output buffer has its gain controlled by an automatic gain control circuit that compares low-frequency swings of the input and output of the trace canceller. The gain of the variable gain amplifier is reduced to prevent the output buffer from saturating and clipping peak voltages on its output. Thus both the variable gain amplifier and the output buffer remain in the linear region. Training pulses from the transmitter are passed through the trace canceller without clipping of peak voltages, allowing the transmitter and receiver to adjust transmission parameters to best match the transmission line. |
