Abstract:
The handover issue is one of the most important challenges in the next generation mobile networks. Traditional handover triggering conditions mainly based on signal strength, while the requirements for other triggering conditions such as user controlled handover or service based handover become an urgent need; especially when the handover is required among different networks. We propose a simple and easy mechanism for exchanging the handover metrics using proof of concept and logical visibility. This handover metrics represent the base in which the handover decision algorithms are constituted on. Metrics information can be transferred not only among different nodes that belong to the same radio access technology but also among different wireless access technologies as well. In this paper, we introduce new fields in the IP option header which are used for the handover metrics information exchange. We focus on some important metrics and how they can be read and written in the IP header. This allows any handover decision algorithm to openly use our scheme in a flexible way. The choice of the IP protocol comes from the trend of the next generation networks, which is based on IP networks.
