Patent ID: 8385936

Claim:
A method of interference suppression in a wireless cellular network, comprising: notifying a first base station of a second User Equipment (UE) that currently suffers downlink interferences from the first base station, when the second UE in an active state suffers downlink interferences from the first base station; and reallocating, by the first base station, spectrum resources for a first UE communicating with the first base station, or, reallocating, by a second base station, spectrum resources for the second UE; wherein notifying the first base station of the second UE that currently suffers downlink interferences from the first base station comprises: receiving, by the second base station, a measurement report sent by the second UE, wherein the measurement report carries a Physical Cell ID (PCI) of the first base station; obtaining, by the second base station, an E-UTRAN Cell Global Identifier (ECGI) of the first base station according to the PCI of the first base station that is reported from the second UE; sending, by the second base station, a UE ARRIVAL message to a Mobile Management Entity (MME), wherein the UE ARRIVAL message carries the ECGI of the first base station; and forwarding, by the MME, the received UE ARRIVAL message to the first base station that forms the downlink interferences on the second UE.
