Abstract
Every layer of the mobile protocol stack contributes to next-generation advanced mobility management (MM).
However, present MM architectures are largely single-layer specific and thus can hardly meet the simultaneous low-
and high-level mobility support requirements. A co-operation of multiple layers would lead to a promising solution.
Notably, there is an increasing interest to adopt cross-layer design for future wireless systems. Through this approach,
the refined systems can obtain extended functionality and/or improved performance, which are hard to gain via a
single-layer signalling. In this paper, we identify and abstract each layer's contributions to various mobility support
tasks. By introducing cross-layer interactions to the TCP/IP protocol stack, we present an IP-based multi-layer MM
architecture taking advantage of contributions from individual and combined layers.
1. Introduction
The complexity and requirements of mobility
management (MM) are growing with the evolution of
wireless systems. The well-established 2G (second
