ABSTRACT:
A method of discovering at least one of a homogeneous and a heterogeneous network module to perform handover with in a wireless mobile communication network is disclosed. More specifically, the method includes establishing a network handover module for converging information from at least one network interface module associated with at least one of a homogeneous and a heterogeneous network handover module into a unified presentation and transmitting a broadcast request message from a mobile station (MS) to a source point of attachment (PoA) which transmits the broadcast request message to at least one interface module to identify whether the at least one interface module supports at least one of the homogeneous and the heterogeneous network handover module and a capability of the at least one of the homogeneous and the heterogeneous network handover module. The method further includes initiating a timer for a specified time period when the broadcast request message is transmitted and receiving at least one response message from the at least one interface module via the source PoA prior to expiration of the timer, wherein the response message indicates that the at least one interface module supports at least one of the homogeneous and the heterogeneous network handover module and the capability of the at least one of the homogeneous and the heterogeneous network handover module.
