  • SIM subscriber identity module
  • WWW World Wide Web
  • Businesses and individuals are increasing relying on the World Wide Web to perform critical activities.
  • a similar revolution to that of the World Wide Web is taking place within the domain of mobile telecommunications where existing network infrastructures are being extended through wireless Internet access.
  • Wireless networks have lead to the development of the 'Mobile Internet'.
  • WAP Wireless Application Protocol
  • WAP has emerged as a global standard for providing Internet communications and mobile telephony services on digital mobile phones, pagers, personal digital assistants (PDAs) and other wireless devices.
  • Wireless devices have become increasingly ubiquitous and the use of mobile phones, pagers, and PDAs, as well as wireless services continues to expand. A large number of these devices are not mobile Internet enabled but have transcended the lack of browser based functionality through that provided by messaging protocols such as the short message service (SMS).
  • SMS short message service
  • SMS is a form of paging that was developed for these wireless devices. SMS enables two mobile devices to exchange text/binary messages. The ability to exchange SMS messages provides the convenience of non-voice based communication and enhanced network connectivity. SMS has a number of technical limitations that have, to date, limited the utilization of the technology in providing collaborative services. Collaborative Internet applications such as chat rooms and instant messaging have proved to be enormously popular Internet-based services. The predecessor to these services was Internet Relay Chat (IRC), which is an Internet Protocol (IP) based service with support for distributed collaboration. Collaboration tools enable distributed users to work together and share information using a variety of approaches.
  • IRC Internet Relay Chat
  • IP Internet Protocol
  • IRC provides a variety of mechanisms for users to collaborate across the World Wide Web with friends, colleagues and others, by subscribing to various channels or chat rooms, to exchange text messages and transfer files. While the Internet is dynamic and flexible in providing users with entertaining and useful ways of communicating, it does not meet the needs of all users. While users interact increasingly through the Internet, they continue to interact off the Internet in more conventional ways, such as multi-medium (phone, fax, whiteboard), multi-temporal (messaging, voice, mail) and other informal means of communication. This desire combined with the increased requirements of workplace mobility has seen a requirement to bridge the divide between the Internet and telecommunication networks.

Abstract

Dans un système de collaboration mobile, des sessions utilisateur sont gérées dans un espace de travail partagé à l'aide d'un serveur espace de travail mobile couplé à un réseau de communication, ce serveur espace de travail mobile communiquant avec des serveurs d'application distants. Lorsqu'une commande utilisateur est reçue d'un utilisateur qui utilise un dispositif mobile comportant un module d'identité abonné (SIM), cette commande utilisateur est traitée et une session utilisateur est établie entre l'utilisateur et un serveur d'application distant. Les applications SIM peuvent être actualisées par le réseau de communication à l'aide d'un serveur système de gestion en communication avec le dispositif mobile contenant un module SIM par les réseaux de communication, et de la réception d'une demande d'actualisation d'une application cadre, et la transmission d'actualisation à l'application cadre par le réseau de communications. Des données peuvent être transmises par un réseau de communication à l'aide d'un système de service d'envoi de messages courts (SMS) et la concaténation de données par la génération de données pour la transmission, la séparation des données en paquets de données segmentés, chacun contenant une donnée d'en-tête, la transmission des paquets de données segmentés, la mémorisation des paquets de données segmentés dans un tampon temporaire, la restauration des données par le reclassement des paquets de données à l'aide des données d'en-tête, et la délivrance des données restaurées à un tampon externe.
