The CN side comprises a realistic implementation based on a DiffServ/MPLS domain with the required QoS and mobility management functionalities.
Finally, the LB module includes the load measurement and mobility management functionalities, which collect cell load ratio and execute the load balancing algorithms.
Section 3 reports the functionality of mobility management scheme and implementation of LAPM scheme.
However, a mobile access gateway (MAG) is required to perform location updates for individual MNNs whenever the mobile network moves to another MAG, as the relay station has no functionality for mobility management.
Mobility management involves two main functions, namely, location management and handoff management [17].
Moreover, registration, authentication, local registration management, and mobility management are also included in the functionalities of the NAS protocols.
Hence, we study the distribution of mobility management based on the decoupling of functionalities into: handover management, location management and data management.
Mobile IPv6 provides the mobility management for IPv6 protocol.
Accordingly, WSDN Controller configures the routers/switches (i.e., has interfaces to routers/switchers) also by factoring in radio-specific functionalities like resource scheduling and mobility management.
Therefore, the mobility management will enable different mobile networks to interoperate with each other to ensure terminal and personal mobility and global mobility services.
