“…Considering that the state space of the MDP is defined by (1) and (2), and the possible set of actions and the transition rates associated to them are defined in Table 1 and Figures 1 and 2, it is necessary to define the optimization functions and the cost/reward associated to them. Since our interest relies on data and voice blocking probabilities, as well as the total throughput, we have defined two different objective functions.…”

ElsevierPacheco Páramo, DF.; Pla, V.; Casares Giner, V.; Martínez Bauset, J. (2012) AbstractThe joint management of radio resources in heterogeneous networks is considered to raise the resource occupation efficiency. We propose joint schemes for admission control and access technology selection with vertical handoff. We determine optimal policies for a radio systems that support two multiple access techniques, TDMA and WCDMA, covering the same geographical area. In addition, the system under study also supports both streaming and elastic traffic. First, we explore different optimization criteria expressed in terms of blocking probabilities and throughput. We accomplish an exhaustive numerical analysis that allows us to characterize the optimal admission policies according to the arrival type and system load. Based on this characterization, we design heuristic policies and compare their performance to ones obtained by previously proposed schemes. This analysis is also done when constraints are added to provide QoS. Second, we also study an extension of the previous system that includes vertical handoffs, in order to evaluate their impact on the system performance. For the four types of vertical handoffs considered, we determine and characterize optimal policies according to the arrival type, system load and vertical handoff action. Since it is not feasible to calculate the optimal policies online, new heuristic policies with vertical handoff are constructed and evaluated. Finally, in order to take into into account the cost of performing vertical handoffs, a new optimization problem is formulated that relates voice and data blocking with vertical handoff costs.

“…The new generation wireless systems allow the subscribers to exploit the availability of multiple radio access technologies (RATs) in the same geographical area to achieve a permanent connection with the best possible performance [1]. This coexistence of various RATs has promoted the interest in joint management of their radio resources.…”

In this paper, we propose an early spectrum sensing(ESS) as an advance preparation for radio-access trial, which enables multi-mode terminals to access the most appropriate radio-access system in a cloud-conceptual base station system where multiple radio access technologies(RATs) coexist. Prior to a random access to one of RATs, a multi-mode terminal conducts a spectrum sensing over entire frequency bands of whole RATs, then select the

“…Coexistence of several access technologies demands the study of joint radio resource management (JRRM), given the objective of providing users with a permanent connection with the best possible performance [1]. Since coordinated control of several radio access technologies improves the use of limited resources [2], a challenge that arises is to find the most appropiate scheme for the main functions of JRRM, such as joint call admission control (JCAC) and vertical handoff (VH).…”

Optimal Joint Call Admission Control with Vertical Handoff on Heterogeneous Networks

Abstract.A joint management of radio resources in heterogeneous networks is considered to raise efficiency. In this paper we focus on joint schemes for admission control and access technology selection using vertical handoff. We study a system where both streaming and elastic traffic are supported, and two radio access technologies covering the same areas are available: TDMA and WCDMA. Optimal solutions for different optimization criteria which can be expressed in terms of blocking probabilities and throughput are found and properly described, and a new heuristic policy is proposed. Finally, in order to provide some understanding of the cost of a single vertical handoff, a new optimization criteria is defined where its cost is found in relation to that of voice and data blocking.
