Abstract: A method of dynamically adjusting quality of service targets for applications and/or subscribers of wireless communication, by reducing or increasing quality of service targets for a group of applications based on overload or under load detection, in order to ensure that actually achieved quality of service levels are adequate, especially when supporting emergency service users.

Abstract: In the method of flexible frequency allocation, at least a portion of a frequency spectrum for a lower priority class of applications is allocated to a higher priority class of applications if overload of frequency spectrum for the higher priority class of applications is detected, an emergency situation occurs, etc.

Abstract: In the method of packet transmission, data packet fragments received from a first mobile station are sent to a second mobile station without assembling and re-fragmenting the received data packet fragments if the first and second mobile stations are in a same cell.

Abstract: A chaotic communication system employs transmitting and receiving chaotic oscillating circuits. One improvement to first-generation systems is the ability to modulate a nonreactive element in the transmitting circuit, thus increasing modulation bandwidth. Other features include insertion of a gain control amplifier in a chaotic receiver; signal filtering in chaotic transmitters and receivers; use of chaotic modulation techniques for cellular telephony applications; dual-transmitter and receiver systems; a dual receiver synchronization detector; interfaces to communication systems; analog chaotic signal modulation; use of multiple chaotic transmitters and receivers; digital algorithm improvement using a cube-law nonlinear component; a Gb-only receiver; a Gb-only transmitter; and positive slope transmitter and receiver systems.
