A large interest in developing commercial Location-Based Services (LBS) and the necessity of implementing emergency call services, have led to the intensive development of techniques for mobile users' localisation. In this paper, a Public Land Mobile Networks (PLMN) -based technique for initial position determination is proposed as an alternative to satellite-based methods in environments with obstructed satellite signals. Two positioning models, based on handset available Received Signal Strength (RSS) measurements from Global System for Mobile Communications (GSM) base stations and the use of Support Vector Machine (SVM) algorithms, are proposed. Performances of proposed models are verified using field measurements, collected in a suburban environment. Models are analysed in terms of positioning accuracy, complexity and latency, and compared to some other promising PLMN-based techniques. Using proposed SVM-based positioning models a median error of 4·3 m–6·2 m and latency of less than a second can be achieved.

Past Data

This chapter is about geographic information systems (GIS) and its relevance to the location-based services industry. One might initially ask how relevant GIS is to a book that is predominantly about automatic identification and its future trajectory. The answer becomes apparent quickly as the reader is introduced to the importance of geocoding information, i.e., geographically linking data such as personal details using a unique ID number. In the past data matching programs have received a great deal of attention from privacy advocates, especially those used for the administration of government procedures. Till now, automatic identification has facilitated electronic services (e-services), allowing an individual to be matched to a fixed address, usually their place of residence. But it is one thing to tag and another to track. Today, we are moving towards a model of tracking and monitoring people as they go about their daily business, in real time. We are no longer satisfied with knowing where an individual lives but we want to know their every move- so that we can estimate traffic congestion on a busy road, design 3G mobile networks that have enough capacity during busy hours, and to ensure someone’s safety when adequate supervision is not available.

4G Mobile Communication

As the location based services develop, more and more researches have been focused on the positioning technologies in mobile networks. The long term evolution advanced (LTE-A) system, commercialized as the 4th generation (4G) mobile communication system, is based on the following key features: the orthogonal frequency division multiplexing (OFDM), the relay, the multiple input multiple outputs (MIMO), the carrier aggregation (CA), and the coordinated multipoint transmission and reception (CoMP). In this paper, the impact of these features on the existing positioning technology specified in the LTE-A standards is systematically investigated. Moreover, two approaches are proposed to take full advantage of these features in terms of positioning technologies and the key positioning parameters, including the reference signal time difference (RSTD) in the observed time difference of arrival (OTDOA) technology and user equipment receiving time subtracting transmitting time (UE Rx-Tx) in the enhanced cell identity (E-CID) technology.

ABSTRACT  Pervasive computer games (PCGs) combine digital mobile technologies and location-based systems by creating an interface between electronic and physical spaces for playing. PCG is a general name for mobile games such as hybrid reality games (HRGs), location-based mobile games (LBMGs), and urban games. Our goal here is to show how these games, along with new digital mobile technologies, have the potential to produce “spatialization,” i.e., to socially produce the space in which they are embedded. I suggest that spatialization is achieved through the use of technology such as sensors and digital mobile networks (smartphones, PDAs, global positioning systems [GPSs], and augmented reality [AR] devices; radio frequency identification [RFID] tags and global system for mobile communications/general packet radio service [GSM/GPRS]; Wi-Fi and Bluetooth). The goal of this article is to examine the forms of spatialization created by the use of location-based services and location-based technologies.RÉSUMÉ : Les jeux mobiles géolocalisés combinent les technologies numériques mobiles avec les systèmes géolocalisés, créant ainsi pour le jeu une interface entre espace électronique et espace physique. Ces jeux comprennent tout jeu mobile tel que les jeux de réalité hybride et les jeux urbains. Mon but dans cet article est de montrer comment ces jeux, de concert avec les nouvelles technologies numériques mobiles, ont le potentiel de réaliser certains types de « spatialisation », c’est-à-dire de créer socialement l’espace dans lequel ils se trouvent. Je suggère que la spatialisation s’accomplit au moyen de technologies comme les capteurs et les réseaux numériques mobiles (téléphones intelligents, assistants numériques personnels, systèmes GPS et systèmes de réalité augmentée; étiquettes d’identification par radiofréquence, systèmes mondiaux de communication avec les mobiles et services généraux de radiocommunication par paquets; Wi-Fi et technologie Bluetooth). Le but de cet article est d’examiner les types de spatialisation créés au moyen de technologies et services géolocalisés.

This paper discusses location-based service for telecom providers. Most of the location-based services in the mobile networks are introduced and deployed by Internet companies. It leaves for telecom just the role of the data channel. Telecom providers should use their competitive advantages and offer own solutions. In our article, we discuss the sharing location information via geo messages. Geo messages let mobile users share location information as signatures to the standard messages (e.g., email, SMS). Rather than let some service constantly monitor (poll) the user’s location (as the most standalone services do) or share location info within any social circle (social network check-in, etc.) The Geo Messages approach lets users share location data on the peer to peer basis. Users can share own location info with any existing messaging systems. And messaging (e.g., SMS) is the traditional service for telecom.

With the rapid development of mobile wireless networks such as 4G and LET, ever more mobile services and applications are emerging in mobile networks. Faced with massive mobile services, a top priority of mobile information systems is how to find the best services and compose them into new value-added services (e.g., location-based services). Hence, service selection is one of the most fundamental operations in mobile information systems. Traditional implementation of service selection suffers from the problems of a huge number of services and reliability. We present an efficient approach to service selection based on computing QoS uncertainty that achieves the best solution in two senses: (1) the time cost for finding the best services is short and (2) the reliability of the selected services is high. We have implemented our approach in experiments with real-world and synthetic datasets. Our results show that our approach improves on the other approaches tested.

Fifth generation mobile technology (5G) targets to meet user demands in terms of improved capability, increased data rate, and best value of service. In order to meet these demands, the 5G technology applies massive multiple-input multiple-output (MIMO) and device-to-device communication (D2D). Also, by making use of location-based services (LBS), it provides value-added services to the users including methods to overcome the energy depletion in the network. The authors discuss the internet of things and its potential to offer novel solutions. Media access control (MAC) sub-layer offers and channel access control mechanisms will enable various terminals or network nodes to interact in a network and prevent collisions. Here, the authors present a complete review related to developing and enabling technologies with the key focus on 5G mobile networks and supporting the growth in traffic for enabling IoT.
