“…There are many examples that provide a partial solution of the tight coupling of management activities, for instance, QoS and routing integrated functionalities, 24 mobility and AAA 25 management protocols (mobility, QoS and security). Chaouchi et al 26 suggest combining mobility, security and QoS signalling in an optimized way to minimize session establishment and optimize network resources usage. The only issue is to replace the existing frameworks of QoS, mobility and security (AAA) with a unified signalling framework.…”

SUMMARYScarce radio resources and the ambition to increase the number of mobile customers with a guarantee of service are pushing mobile communication systems from homogeneous non-service convergent 2G and convergent-service 2.5G and 3G wireless systems to heterogeneous integrated and convergent service 4G networks. This evolution has had several consequences from network design, control and service management points of view. In the emerging integrated 4G networks one of the issues is the signalling of information related to different control purposes such as QoS, mobility and security signalling. In fact, some questions such as which are the candidate signalling protocols, and which approach of integrated signalling to be adopted (unified versus non-unified) need to be considered in the context of the emerging 4G integrated network. This is precisely the scope of this paper. We first identify the requirements related to mobility, security/AAA and QoS signalling, then we consider candidate signalling protocols and we propose possible approaches in the integration of signalling in the context of 4G networks.

“…The wired access network connects the wireless access networks to the core network. The authentication, authorization, accounting (AAA) server in the wired network is used to achieve the authentication of the mobile users; it is used in interaction with the mobility protocol [10]. We assume that there is already a mobility management protocol deployed between the mobile nodes and the access routers.…”

Wireless networks bring a new market to service providers and terminal manufacturers. In fact after the success of the wired internet, wireless and mobile internet arrives with the ambition of providing new services to Internet users. However wireless networks face important challenging issues before attaining a similar or better success than the wired Internet. These issues are mainly related to the classical QoS, mobility, security problems, and the wireless specific problems such as the radio resource characteristics. In this article we are interested by the mobility problern and particularly the handover management problem. We introduce a policy based handover and we propose to combine the mobility management with the policy based architecture in order to achieve policy based handovers that are triggered not only on the signal strength basis, but also on policy constraints such as cost, resource availability or Ioad balancing. The policy based architecture will provide the handover triggering mechanism and the decision support related to the best next cell where the mobile node will move. We also introduce mobility parameters in the Service Level Specification (SLS) that specifies the handover type, the accepted handover packet loss, and the accepted handover delay. Basedonthese SLS mobility parameters, the QoS service classes can be mapped to the smooth (minimum packet loss), the fast handover (minimum delay), or the seamless handover (fast and smooth).

“…There are many examples that provide partial solution of the tight coupling of management activities, for instance, QoS and routing integrated functionalities [6], mobility and AAA [7] or QoS and security [8]. A more complete solution in [10] proposes to extend COPS (Common Open Policy Service) protocol to provide the interaction among the dedicated management protocols (mobility, QoS and security).…”

Abstract-4G wireless and mobile communication networks have the ambition to integrate heterogeneous wireless access network technologies combining mutual advantages and thus offering a variety of services to the users, maximizing their satisfaction on the one hand and maximizing the network and service providers' profits on the other hand. However, this integration is not achievable without challenges. In this paper, we present related system integration requirements and provide a new framework to support the integration of 4G networks and services. This framework uses a policy based networking concept in order to provide the unified control in the oncoming 4G networks and services. We also provide an analysis of the candidate signaling protocols in this framework. Two approaches are described: i) The unified QoS, mobility, and security signaling and ii) the heterogeneous QoS, mobility, and security signaling. In addition, we introduce user, terminal, network and service profiles and management in order to provide a user centric approach and consider different user, terminal, network, and service constraints in order to better adapt the user service as well as the network configuration to these constraints. Finally, we give a short estimation on the composition of exchanged signaling data with respect to the aspired level of integration.
