A system for estimating interference on a cellular network includes a processor and a non-transitory computer readable medium with computer executable instructions stored thereon. The computer executable instructions perform the following method when executed by the processor: causing the processor to receive from a user equipment, first information indicating a strength of a signal received at the user equipment from an interfering base station; causing the processor to receive second information indicating an airlink utilization of the interfering base station; and causing the processor to process the first information and the second information according to an estimation function to produce an interference estimate.

Neighbor cell interference estimation

An apparatus and method provide for synchronized operation of encryption processes at two remote communication terminals. A first one of the terminals detects information associated with a current time during the establishment of a connection between the two terminals. The current time information is then utilized to create a start encryption time. That start encryption time information is transmitted from the first terminal to the second terminal. Both terminals then monitor the passage of time and begin encryption in a synchronous manner when the current time matches the start encryption time.

Method for synchronous encryption over a communication medium

A method and an apparatus provide for controlling a remote unit's requests to access network resources in a wireless communication network. The method and apparatus scale back the frequency with which the remote unit attempts to establish a connection with a base unit, which connection would provide dial tone to a communication device associated with a remote unit. In accordance with the method, with each unsuccessful attempt to establish a connection with the base unit a retry timing interval is extended, thereby throttling back the number of establishment attempts by the remote unit.
