Abstract

The aim of this research paper is to critically analyze one of the integrated WLAN-cellular network architecture which third generation partnership project (3GPP) has also included in its release 6 i.e. generic access network (GAN) formally called unlicensed mobile access (UMA). This article analyzes the limitations of the above mentioned solution and present an architecture for future heterogeneous networks using a novel hybrid approach of network discovery, where the network will broadcast the updated network information using cell broadcast center (CBC) to the mobile station/user equipment (MS) and the MS may also enquire from the network the additional information regarding the available networks, as opposed to centralized technique used in the existing cellular networks. The proposed solution suggests a network information repository (NIR) embedded in the core network, being populated with information of all the available radio access networks (RANs) in a specific location. The information obtained from NIR will help the MS to identify the network elements ahead of time and communicate with these elements in advance. This will help the MS to fetch the general information about the available networks and select the desired network ahead of time and thus seamless connectivity/ handover will be possible for the end user.
支持未来异构网络中网络发现的体系结构
本研究论文的目的是批判性地分析第三代合作伙伴计划(3GPP)在其第6版中也包含的集成wlan -蜂窝网络架构之一,即通用接入网(GAN),正式称为无授权移动接入(UMA)。本文分析了上述解决方案的局限性,并使用一种新的网络发现混合方法为未来的异构网络提出了一种体系结构,其中网络将使用蜂窝广播中心(CBC)向移动站/用户设备(MS)广播更新的网络信息,而MS也可以从网络询问有关可用网络的附加信息。与现有蜂窝网络中使用的集中式技术相反。所提出的解决方案建议在核心网络中嵌入网络信息存储库(NIR),其中填充了特定位置的所有可用无线接入网(ran)的信息。从近红外获得的信息将有助于MS提前识别网络元素并提前与这些元素进行通信。这将有助于MS获取有关可用网络的一般信息,并提前选择所需的网络,从而为最终用户提供无缝连接/切换。
