Patent ID: 8548476

Claim:
A method of managing an X 2 interface, comprising: finding by a first eNB, a new neighboring cell, which is a second cell corresponding to a second HeNB; determining by the first eNB, an access mode of the second cell; and establishing a first X 2 interface between the first eNB and the second HeNB when the access mode of the second cell is an open mode or a hybrid mode; wherein establishing the first X 2 interface between the first eNB and the second HeNB comprises: determining whether the second HeNB is connected with a mobility management entity through a HeNB gateway when the first eNB is a macro eNB, if yes, establishing a gateway proxied X 2 interface between the first eNB and the second HeNB, and if no, establishing a direct X 2 interface between the first eNB and the second HeNB; and determining whether the first eNB and the second HeNB are connected with a same mobility management entity or a same HeNB gateway when the first eNB is a HeNB, if yes, establishing a direct X 2 interface between the first eNB and the second HeNB, and if no, establishing a gateway proxied X 2 interface between the first eNB and the second HeNB; checking an available bandwidth of the first X 2 interface; and adjusting an interacting frequency of the interference coordination information dynamically based on the available bandwidth.
