Abstract: A method of reducing packet loss resulting from header compression during data transmission comprising of calculating, by a transmitter, the difference between one or more delta fields of each packet among a plurality of packets and a base frame of data wherein for at least a portion of the packets, the base frame is a packet other than a packet immediately preceding the packet for which the difference is calculated, encoding the difference and compressing the plurality of packets using the transmitter; transmitting, using the transmitter, the plurality of compressed packets and an uncompressed full-header packet through a communications channel to a receiver, receiving the plurality of compressed packets and the uncompressed full-header packet by the receiver, and decompressing, by the receiver, the plurality of compressed packets using the difference between the one or more delta fields of each packet among the plurality of compressed packets and the base frame.

Abstract: A method of providing a recovery channel for a common transmission network of remote devices comprising encoding data that contains information about a primary carrier signal, modulating the encoded information, spreading, the modulated encoded information such that a secondary carrier signal results, combining, the spread secondary carrier with the primary carrier signal such that the spread secondary carrier signal occupies at least a portion of a bandwidth of the bandwidth pool, transmitting the combined primary and secondary carrier signals across a communications link having a plurality of remote carrier signals also being transmitted across the communications link to a remote receiver and sharing a same bandwidth pool (or multiple bandwidth pools), and reestablishing the communications link with the primary carrier signal after a loss of the communications link using the information about the primary carrier signal contained in the secondary carrier signal to recover one or more network configuration parameters.
