Mobile agent platforms and systems. Mod- ern mobile telecommunications evolve towards value-added, on-demand services in which the need for communication becomes frequent and ongoing, and the nature of the commu- nication becomes more complex. The services of the future will be available ‘a la carte’, allowing subscribers to receive content and applications when they want it.. Introducing Mobile Agents (MAs)...

In the Intelligent Network (IN) architecture, the control of the network resources is performed by the signaling plane, whereas the service creation, deployment, and provi- sioning is performed by the service plane. This separation allows introduction of new services and service features without changing the basic functionality of the network for the establishment and the release of resources such as...

The features used are included in the IPv6 (Internet Protocol version 6) protocol stacks. Flexible broadcast can be achieved through enhancements to the IPv6 protocol stack and a DHCP extension for workgroups.. The hosts of a workgroup are attached to the same LAN segment, and broadcasting can be used for server detection, name resolution, and name reservation.. Switched LANs share...

Transmission from CBR traffic may reserve an incremental series of slots in the duration of their transmission. The QoS requirements for the data-transfer service of the MAC protocol include support for user-defined traffic types and connection parameters. Therefore, for interoperability requirements, the changing topology of a wire- less network, inadequate security and reliability of the medium, and protocol-specific management functionality...

Mobile devices have a unique set of features that must be exposed in the Web, in order to enable the creation of advanced telephony services that include location-based services, intelligent network functionality, including integration into the voice network, and voice/data integration.. The WAP pro- tocol stack has a layered design, and each layer is accessible by the layers above, and...

Origin server-side applications can emit content in one or more encoding sets and can accept input from the user agent in one or more encoding sets.. The WTA user agent has the capability for interfacing with mobile network services available to a mobile telephony device, that is, setting up and receiving phone calls.. In the client/server model, a client requests...

XML, RDF, and CC/PP. CC/PP – USER SIDE FRAMEWORK FOR CONTENT NEGOTIATION 119. 7.3 CC/PP – USER SIDE FRAMEWORK FOR CONTENT NEGOTIATION. A CC/PP is a collection of the capabilities and preferences associated with user and the agents used by the user to access the World Wide Web. The CC/PP proposal describes an interoperable encoding for capabilities and prefer- ences...

This allows the mobile user to stay connected to the network. The wireless connection is most usually accomplished by the user having a handheld terminal or a laptop computer that has an RF interface card installed inside the terminal or through the PC Card slot of the laptop. The range of these systems depends on the actual usage and environment...

determining the path to take from the ingress point to the egress point in the network. In the Strowger exchange routing was performed on a step-by-step basis, using the pulsed make and break signalling from the telephone dial to step electromechanical selectors.. This is similar to what would have occurred in the second exchange opened in the UK.. In this...

We pass by transmission on the way to the Intelligent Network (IN) because it is important to understand how all the switching and signalling nodes (not to mention voice links) are connected together. One of the big culprits for. ‘noise’ on the line is cross talk. External noise in the form of interference from electricity mains cabling and other electronic...

The Telcordia standards are used mainly in North America, whilst the ITU-T standards are relevant in pretty much the rest of the world. The basic aim of IN is to decouple the service logic from the control of the switch fabric, a stage further than could be achieved by the use of a stored program controller, and to create a...

Mobile Networks. Mobile telephony networks have been a phenomenal success story since their introduction in the mid- to late 1980s. The 3G label is based on the generally accepted premise that the first-generation cellular networks are the analo- gue-based ones first made popular in the late 1970s and early 1980s (AMPS in the US, TACS in the UK, NMT450/900 in...

In the case of packet-based networks such as the Internet, since this is the one of specific interest to us, the bottom two layers of the OSI stack are populated with technologies that differ based on their geographic bound- ary: local area, campus or metropolitan area and wide area.. This is not meant to undermine the importance of any of...

Access is arguably the most important part of the network infrastructure, since it is the point at which all revenue-generating customers come into contact with the network. It is also an area of great diversity from basic telephone access through private exchange and Automatic Call Distribu- tor (ACD) connections, not to mention HFC cable Integrated Access Device (IAD) protocol stack...

So a specific chapter entitled voice and data convergence could jar a little with the reader, however, this chapter was prompted by the words in the Interna- tional Telecommunications Union telecommunications (ITU-T) I.121 specification ‘‘The need to integrate both circuit- and packet-transfer mode into one universal broadband network. It is interesting to reflect that what we now start to see...

More recently information and the way it should be presented with its roots in publishing has found its way to the top in the form of markup languages. The long history of telecommunications as a real-time systems design problem has in the past necessitated optimisations in the use and encod- ing of information. It is this increase in capability, that...

Directories – More Than Just Information Storage. One of the key issues that directories will resolve for the next-generation networks is the dynamic nature of the future services and the desire to reach services based on useful text- based naming.. In the previous chapter on representing information we explored a number of exciting uses of Extensible Markup Language (XML) to...
