A new mobile information environment has been gradually formed with the rapid development of the computer network technology in the world. In this environment, the mobile information service in the university library is able to meet the changing need of readers for the specific information online and need not visit libraries. The potential demand, opportunities and challenges of the mobile information service in the university library are analyzed respectively. At last, some advices are proposed to provide a better mobile information service in order to meet readers’ need for information in today's society.

Suitable Location

A guidance and information service for a University library based on Wi-Fi signals using fingerprinting as chosen localization method is under development at TU Wien. After a thorough survey of suitable location technologies for the application it was decided to employ mainly Wi-Fi for localization. For that purpose, the availability, performance, and usability of Wi-Fi in selected areas of the library are analyzed in a first step. These tasks include the measurement of Wi-Fi received signal strengths (RSS) of the visible access points (APs) in different areas. The measurements were carried out in different modes, such as static, kinematic and in stop-and-go mode, with six different smartphones. A dependence on the positioning and tracking modes is seen in the tests. Kinematic measurements pose much greater challenges and depend significantly on the duration of a single Wi-Fi scan. For the smartphones, the scan durations differed in the range of 2.4 to 4.1 s resulting in different accuracies for kinematic positioning, as fewer measurements along the trajectories are available for a device with longer scan duration. The investigations indicated also that the achievable localization performance is only on the few meter level due to the small number of APs of the University own Wi-Fi network deployed in the library. A promising solution for performance improvement is the foreseen usage of low-cost Raspberry Pi units serving as Wi-Fi transmitter and receiver.

Information Broker

From the 1994 CAIS Conference: The Information Industry in Transition McGill University, Montreal, Quebec. May 25 - 27, 1994.The majority of libraries still provide the majority of their services for free. But fee-based information services attached to non-profit making institutions such as libraries is not a novel concept any longer. The information explosion has brought many changes to, amongst others, the university library and at present industry and commerce rely heavily on the expertise offered by the staff of those libraries.This paper does not propose to address any ideological issues of "feeversus free" but would rather focus on the following: 1 the need for industry and commerce for utilizing the university library and its resources;2 the university library as information broker with reference toinformation skills complemented with specialized subject knowledge and experience 3 the organization of the wide range of services offered and the pricing of these services; and4 a short, but detailed description of INFOBANK, a dynamic andsuccessful regional fee-based information service to industry and commerce at the library of the University of Stellenbosch, South Africa.A university library can therefore be even more effective in promoting access to information by making it available in the community, albeit for a price. Libraries interested in establishing such fee-based services should nevertheless be aware of the pitfalls associated with the creation and management of these services. Knowledge of the latter will undoubtedly help establish a programme that serves the needs of clients whilst contributing towards the overall image of the parent institution.

Fast Access

The rapid development of computer network technology and information technology, brings greatly facilitate and enrich people's lives for information transfer and fast access, improves work efficiency. At the same time, the network information security is followed. How to ensure the network information is transferred security, which is the problem that various network information systems must face, and also a difficult and hot issue to be researched. In this paper, a variety of effective network security technologies are studied and corresponding implementations are provided for the information network system in the university.
