Systems and methods that provide a mechanism to relocate functions from one gateway to another gateway in a wireless communication network are disclosed. The gateway can implement an access service network (ASN) gateway in a WiMAX based network with a number of functionalities co-located on the gateway such as an authenticator, an anchor FA, an anchor DPF, a PMIP client, and a prepaid client. These functionalities can then be relocated from a first ASN gateway to a second ASN gateway. The proposed system and method reduces the messaging needed for the relocation and the number of components in the network, which can save capital and operating expenses. Additionally, the reduced messaging can reduce latency and delay in the process of relocating, which saves bandwidth and increases the level of service provided to the user.
