Abstract

[From the preceding studies, we can see that traffic load sharing is essentially important to maximize the interworking effectiveness. As discussed in Chaps. 2 and 3, the voice and data traffic load is distributed to the coupled systems via access selection and call admission control, which properly differentiates upward/downward vertical handoff calls, horizontal handoff calls, new calls in the cellular-only area and the double-coverage area. The impact of user mobility is also examined in Chap. 3. Nonetheless, the research is focused on vertical handoff calls crossing WLAN borders as most previous works. Actually, access reselection can also be performed via dynamic vertical handoff within the overlay area. In [22], there is some initial study on dynamic session transfer in hierarchical integrated networks as an analogy to task migration in distributed operating systems. However, little analytical work considers the dynamic vertical handoff within the overlay area triggered by network states instead of user mobility. As the dynamics of both integrated systems are involved, the load sharing problem becomes very complex, particularly for a multi-service scenario. In this work, we present a size-based load sharing scheme for voice and elastic data traffic in the cellular/WLAN integrated network.]
