Abstract: A method and apparatus for detecting external interference on an uplink channel of a serving cell in a communication network, such as a Long Term Evolution (LTE) network. Detecting external interference includes identifying neighbor cells of the serving cell and obtaining neighbor cell data associated with each neighbor cell. For each neighbor cell, a processor estimates a noise-rise contribution resulting from communication between the neighbor cell and user equipment based on the neighbor cell data. The processor generates a noise-rise threshold for the serving cell based on the noise-rise contributions estimated for the neighbor cells. Thereafter, the processor obtains a noise-rise measurement at the serving cell and generates an alert indicating external interference when the noise-rise measurement exceeds the noise-rise threshold.
