    Certain embodiments of the present invention provide a system and method for optimizing a self-organized network (SON) for providing automatic neighbor relationship (ANR) operations to obtain updated Macro-BS and WEAP neighbor information around the WFAP. In one embodiment, a WFAP detects a change in base station information. The WFAP then sends updated base station information to a SON server for validation. Upon receipt of validation from the SON server, the WFAP updates its neighbor relationship table with the updated neighbor base station information.

    [5] A problem with the current ANR design is unreliable or out of date. neighbor information. WFAP scanning may be limited to initializing WFAP. The WFAP can obtain neighbor base station information by scanning for nearby base stations or by obtaining a neighbor list from the sister operator based on the location of the VVAP. However, the constructed neighbor list, which is based on the initiation of WFAP, can be unreliable for many reasons. For example, a neighboring base station may not have a business relationship with a Network Service Provider (NSP) for a WFAP (it is also worth noting that the NSP 'identity for a WFAP does not have to be the same as for a neighboring base station); a neighboring base station may not be in operation (for example due to on / off voltage); or a neighboring base station may not be accessible to a mobile station.
    [8] Some embodiments of the present invention provide a system and method for optimizing a WiMAX self-organized network for providing automatic neighbor operations to obtain updated macro-base station information and WFAP. neighboring base station information to surrounding 'WFAP. 5 10 15 20 25 30 g [0011]
    [9] WFAP a change in neighboring base station information_ Then the WFAP transmits updated. neighboring base station information to a SON server for validation. Upon receipt of validation from the SDN server, the WFAP updates its neighbor relationship table with the updated neighbor base station information.
    [10] According to certain embodiments of the invention, the SON server detects a change in neighboring base station information. Then the SONs server sends updated base station information to vvFA-Pm i i i i i i BRIEF 'DESCRIPTION OF THE DRAWINGS -l the drawings, where the same reference numerals refer' to similar components: i

    [14] We now refer to Fig. 1 ~, when a WFAP detects that the information of an adjacent base station has changed, this may be because a mobile station (MS) reports a related message, such as IVlOB_SCN-REQIREP or MOB__MSHO - REQ . or by some form of uncontrolled or unedited handover. in
    [15] WFAP detection of a change in a neighboring base station information can be accomplished using the following. steps or signals. As number one, WFAP detects a change in a neighboring base station's information. As a number two, WFAP sends a Configuration Update -Req to a SON server, where Configuration Update _Req includes the updated information of the neighboring base station.
    [16] We now refer to Fig. 2, when the SON server detects that the information of a neighboring base station has changed, this may be due to some form of alarm information. For example, an adjacent BS / WFAP may be out of order (for example, mains disconnected); some form of configuration information, such as installing a new BS / WFAP; or removal of an existing base station (BS) / WFAP, or NRT control (for example, if a cell Å is a neighbor of a cell B, in general, 'cell B' is also a neighbor of a cell A).
    [17] SON server detection of a change in a neighbor's information can be accomplished by the following steps or signals.
    [18] Described, it will be apparent to those skilled in the art that many modifications are possible without departing from the inventive concept herein.
    The invention is therefore not limited beyond the spirit of the appended claims. Although embodiments of the invention have been shown and
