23 Nov 2006 18:04:35 Access Gateway With the demand for wireless services increasing, it becomes essential for mobile operators to deploy, upgrade and manage an extensive range of voice and data services efficiently in an economical manner. The service providers are further strained by the different network build-out strategies after consolidations in the industry and by the price and transmission and management equipment. There is a need to integrate the functionality of the various devices and augment revenues, while bringing down capital and recurring transmission costs and improving wireless backhaul network management. Access Gateway is the solution that takes care of all these. An Access Gateway is a link between a telephony network and other networks such as the Internet. With the importance of Internet on the rise, Access Gateways assume greater importance as components of Access Mediation. Access Mediation is the method of analysing and curbing signalling traffic between networks, resources and users by segregating Signalling System 7 (SS7) traffic. This process makes it possible for carriers to check each signalling message passing through the network. Each message is examined carefully against the carriers policy to decide whether to allow or deny or transform the message traffic. Access Mediation instruments are generally used to reduce the risks associated with the extensive interconnection and network convergence by offering revenue assurance, advanced signalling security and prevention of fraud. An Access Gateway permits networks based on diverse signalling protocols to get interconnected. For instance, the mergers of telephone companies have generated the necessity to interconnect networks based on different signalling specifications. Wireless networks based on GSM have to interconnect with networks based on IS-41 the network standard that permits all switches to exchange information about subscribers. The protocol conversion necessary to interconnect such networks is provided by the Access Gateway. Additionally, providers are deploying TCP/IP-based networks instead of SS7 for specific signalling. The TCP/IP-based networks are utilised to interconnect distant networks, which is a cost-effective solution. An Access Gateway provides desktop access experience similar to that the users have within the network, thereby minimising training and support. Moreover, an Access Gateway automatically provides reconnection to applications and documents when users move to another location and device and thus enhances productivity. Through an Access Gateway, users can get secure access to any application, resource, voice or data including Web applications and telephony services using VoIP softphones, among others. There is no need to customise any application. Access Gateway provides reinforced data security. Organisations can conveniently furnish desk-like access to their remote users from anywhere without additional expenditure and the cumbersome process of installing, updating and backing up client software on each of the devices. It is swift, smooth and economical to deploy and manage Access Gateways. Links: Caymas Systems' Access Gateways Content Team -- BSNL Portal -- Intelligroup Asia Pvt. Ltd. |
