“…In the user-driven selection the user terminals are expected to make network selection decisions, explicitly intitiated by the user. The network-initiated handover is typically defined as action taken in the network to initiate the handover based on either: (1) radio link quality (e.gl signal strength, signal-to-noise ratio), (2) introduction to the network of new network devices; or new service requirements; (3) events generated in the network (e.g. resource management, locationbased optimization).…”

Abstract: The problem of efficient use of resources in wireless access networks becomes critical today with users expecting continuous high-speed network access. While access network capacity continues to increase, simultaneous operation of multiple wireless access networks presents an opportunity to increase the data rates available to end-users even further using intelligent cross-network resource sharing. This paper introduces a new Integrated Mobility and Resource Management (IMRM) framework for automatic execution of policies for cross-network resource sharing using traffic offload and pre-emptive resource reservation algorithms. The presented framework enables both mobile-initiated and network-initiated resource sharing policies to be executed. This paper presents the framework in detail and analyses its performance using extensive ns-2 simulations of the operation of a set of static policies based on measured signal strength, and dynamic pre-emptive network-initiated policies in a WiFi/WiMAX scenario. The detailed evaluation of the static policies clearly shows that the quality of voice applications shows large deviation, mostly due to very different levels of delay in access networks. Based on these conclusions, this paper presents a design of two new dynamic policies and shows that such policies, when efficiently implemented using the new IMRM framework can greatly improve the capacity of the network to serve voice traffic with a minimal impact on the data traffic and with a very low signalling overhead.

“…Then, in order to overcome this problem and to benefit from technology diversity, an automatic interface selection based on instantaneous and practical constraints and user preferences as well as operator and network resources management constraints has become an inevitable trend. In reality, several actors (such as the user, the terminal, the applications,…) affect the best network selection decision [1,2]; each one tends to influence this decision to satisfy its benefits. Moreover, the networks heterogeneity with different characteristics and mobility management policies constitutes a technical constraint that makes the selection decision more complex.…”

“…Moreover, the networks heterogeneity with different characteristics and mobility management policies constitutes a technical constraint that makes the selection decision more complex. In this context, several architectures and schemes using multi criteria decision making approaches have been proposed in the literature [1,[3][4][5][6][7]. These approaches have treated principally three approaches: a decision taken by the MT [5], by the access network [6] or a cooperative solution taken by both of them [7].…”

“…Mechanism proposed in [1] is based on a unique decision process that uses non-compensatory and compensatory multiattribute decision making jointly on the network side to assist the terminal to select the top candidate network. The mechanism proposed in [3] optimizes the network selection process through minimizing the average power consumption cost and the average user dissatisfaction and models the problem of multi constraint access selection as a variant of bin packing problem which is a too complex solution.…”
