The wireless ubiquitous network and various communication services are expected to be realized. The wireless ubiquitous network is defined as the converged network to integrate the mobile network with the fixed IP based network. First, the concept of wireless ubiquitous network architecture is shown which is based on IMS standardized by 3GPP. Next, Parlay is described as the solution of Open API approach...
RFID (radio-frequency identification) technology is widely used for supply chain management and inventory control. Furthermore, RFID has been recognized as a tool to realize a ubiquitous environment. The typical architecture of RFID applications comprises RFID tags, which are embedded in or attached to an object, an RFID reader, and IS (information services) server. The RFID reader reads the code...
In a saturating telecommunications marketplace network operators want to rapidly deploy services with minimum capital investment, while maximizing on revenue from service usage by customers. One way to achieve this is to create interfaces for 3rd party service and content providers to offer their applications and services to users. Composing and bundling of these services will essentially create new...
The NAC (network access control) technology which enforces the endpoint access decision based on the collected endpoint security status information and platform measurement information has been developed by various companies and has been widely deployed in intranets. Besides intranet, mobile telecommunication networks also find NAC is required. This paper introduces the main NAC solutions in industry...
This paper introduces an open source instant feedback system using wireless messaging technologies. The system targets users' in-hand technologies and allows their participation in any feedback process through simply sending an SMS message or through a dedicated mobile application. Additionally, the system provides an advanced tool for authoring questions, visualizing results, viewing statistics and...
As a smart consumer, there is always a need for us to identify the quality of the goods we want to buy, such as trying to choose the better mango amongst the others in a fruit market. With the popularity of the mobile phone and the maturity in wireless messaging technology, it is no more a dream for us to get the information we want anywhere, anytime. This paper proposes a new mobile data service...
To support m-commerce applications such as mobile e-auctions, an efficient service discovery mechanism is required in a scenario where service directories are stored on distributed servers and users are mobile. E-auction services discovery in dynamic mobile environments poses many challenges such as dynamism in E-market, service access time, service filtering, lack of automated tools for searching...
Multi domain networks can be used in several scenarios including military and enterprize networks. In such networks each domain might be under different administrations, which might not want to share all information among them regarding their domain configurations. In such multi domain networks, one major challenge is the support for mobility. We propose a new multi domain mobility (MDM) system that...
This paper analyzes the data access pattern to the gateway cache for the better design of direction-based query scheduling scheme, based on the real-life trajectory data. After defining an advanced route information service in which each vehicle requests the data items associated with all links along the route in the vehicular telematics network, experiments are conducted to investigate the queue...
Since 2005 the Taiwanese government has invested over $1.2 billion into the M-Taiwan program to bolster Taiwan's broadband mobile communications industry and infrastructure. In addition to building a fiber backbone and providing R&D grants for developing new technologies and novel applications, it has also co-funded the constructions of four large-scale test networks. The Kaohsiung County broadband...
With mobile terminals and wireless network environment constantly being improved, people are using mobile instant messaging (IM) products more frequently. We provide a novel design based on Jabber and FCAPS model to meet the rapidly growing and changing needs. Jabber provides an open, secure, real-time communication technology. Network management has always been a key aspect of communication networks...
We describe a framework for wireless sensor network (WSN) based mobile mashup applications. The framework consists of four functional components: WSN, mobile gateway, context management platform, and mashup server. The WSN deployed in the application domain senses the physical phenomena and the human-environment interaction and expresses them in sensor readings. The mobile phone is used as the gateway...
Existing solutions for building wireless mesh networks suffer from reduced efficiency. This is due to lack of reliable self-configuration procedures that can dynamically adapt to varying network conditions, lack of efficient and scalable end-to-end quality of service (QoS) support, and lack of generalized and seamless mobility support. Therefore, ensuring a certain level of QoS to mobile users is...
With the rapid advancement of wireless network technologies, Mobile Instant Messaging (IM) has become a major application in the telecommunications industry. Firstly, this paper introduces recent research and development efforts in constructing mobile IM systems. Secondly, it advances a new service model and implementation mechanism based on Jabber/XMPP. The communication protocol of our system provides...
In this paper we describe a simulation/emulation software which can simulate the call flows from a mobile originated c all a nd a mobile terminated c all scenario in a Release 4 UMTS mobile communication network. This software also tries to emulate the Mc interface that resides between the Mobile Switching Center Server and the Circuit Switched Media Gateway. The simulator is capable to send real...
