Through the study on “HetNet mobility enhancements for LTE”, it was observed that handover (HO) performance in heterogeneous networks (HetNets) deployments is not as good as in pure macro deployments. It also showed that high speed user equipment (UE) suffers much higher handover failure (HOF) rate than low speed UE. The major cause of HOF is the failure of handover command transmission from source...
To reduce the burden on the mobile host and provide efficient mobility management, network-based mobility management such as pMIPv6 has been standardized. But, this protocol is usually used in a single domain. Thus, inter-pMIPv6 mobility management protocol is needed. We propose inter-LMA handoff and location management scheme using core-edge separation network for global mobility management. The...
