Architecture and schemes for intelligent mobility management in future mobile telecommunication systems

We present a novel terrestrial mobile network architecture that aims at the simplification of mobility management for the terrestrial mobile telecommunication networks. The work is in line with the UMTS approach. The proposed architecture uses the hierarchical cell concept and facilitates strategic placement of database control. A macro-cell based approach for location updating and a combined macro/micro cell based paging control plays a key role in our proposal. Another significant feature of the proposed scheme is that, each micro-cell has the same signalling load, regardless of the location updating traffic. A location agent (LAg) that is co-located with signalling transfer point (STP) and hierarchically structured is also proposed to reduce mobility management signalling traffic to and from the HLR. A swap technique is applied at the location databases, which further reduces the signalling traffic. The simplifications achieved through the use of this architecture benefit both location updating and paging procedures by optimising the traffic in both cases
