The Third Generation (3G) cellular networks provide ubiquitous connectivity but low data rates, whereas Wireless Local Area Networks (WLANs) can offer much higher data rates but only cover smaller geographic areas. Their complementary characteristics make the integration of the two networks a promising trend for next-generation wireless networks. With combined strengths, the integrated networks will provide both wide-area coverage and high-rate data services in hotspots. There are many aspects involved in their interworking, such as mobility, security and Quality of Service (QoS) provisioning. In this paper, we present a survey of most recent interworking mechanisms proposed in the literature, and outline some important open issues to achieve seamless integration.

    • "But regarding the level of coupling between cellular and Wireless networks, two main integration architectures are broadly considered; loose and tight/very tight coupling. In Song et al. (2007), the advantages and limitations of each kind of coupling were thoroughly discussed. In this paper, however, decision key factors based on all affecting parameters such as terminal type, user speed, prediction, connection history, traffic load and carrier-to-interference ratio (C/I), are analysed.

    ABSTRACT: In this paper, basic mechanisms of interoperability between long-term evolution LTE as 4G cellular system and mobile WIMAX networks as 4G wireless are introduced. Two cost-based mechanisms are investigated to represent two interoperability functions: initial network selection INS and inter-network handover INH. Simplified approaches that ease the evaluation of related cost functions CFs are proposed. The necessary assumptions for the implementation of a joint LTE-WIMAX system level simulator platform, through a real coexistence scenario, are proposed. Numerical results show a considerable enhancement in terms of selected performance metrics such as blocking and dropping probabilities. Weight values readjustments are also tested to highlight the critical key factors affecting interoperability mechanisms.

    • "Different characteristics have been proposed, like usage cost, power requirement, offered bandwidth, package delay, coverage, price, throughput, and mobility. [1] [2] [4] [5] In decision-making process, maximum value of these characteristics will be set as standard at first. Then, all the candidate networks will be compared to these standard values to get a mark. "

    ABSTRACT: In establishing of next-generation wireless networks, finding the best connection is a key challenge. An algorithm based on utility theory has been proposed in this paper to evaluate all these wireless networks, in terms of network performances and user behaviours. By applying the utility function, user satisfaction can be mathematically calculated in terms of the criterion received by each user. A single criterion function with sigmoid type has been chosen, by which the user behaviour can be perfectly described. Next, a novel aggregate method has been added, with user preference involved, to calculate the overall utility. The network with highest utility is the best choice for user. Both theoretical analysis and practical simulation have proved the effectiveness of our proposed algorithm.

    • "IEEE 80.11b operates in license-exempt band i.e., 2.4 GHZ and provides a data rate up to 11Mbps [5]. Whereas, 802.11a and 802.11g operate at license-exempt band i.e. 5GHZ and 2.4GHZ, respectively, and provide data rate up to 54Mbps[6]. Although, WLAN coverage ranges are limited to 300 meters. On the other hand, UMTS provides global coverage; however, the data rate is limited to the maximum of 2Mpbs at high operational costs. "

    ABSTRACT: To provide seamless internet connectivity anywhere at any time to the mobile users, there is a strong demand for the integration of wireless access networks for all-IP based Next Generation Networks (NGN). The Wireless Local Area Network (WLAN) is capable of providing high data rate at low cost. However, its services are limited to a small geographical area. Universal Mobile Telecommunications System (UMTS) networks provide global coverage, however, cost is high and the provided data rate do not fulfill the requirements of bandwidth intensive applications. By integrating these two promising technologies; UMTS and WLAN several benefits can be achieved, i.e., load balancing, extension of coverage area, better Quality of Service (QoS), improved security features, etc. Therefore, the integration of these two technologies can provide ubiquitous connectivity and high data rate at low cost to wireless clients. In this paper different integration mechanisms of UMTS and WLAN are investigated. More precisely, an integrated mechanism for the integration of UMTS and WLAN based on two different variations of tight coupling, i.e., interconnecting WLAN with Serving GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN) is designed and analyzed. The simulated results reveal that the GGSN-WLAN integration performance is better than the SGSN-WLAN integration for all the applied applications and measurement parameters.
