Call forwarding, or call diversion, is a telephony feature of all telephone switching systems which redirects a telephone call to another destination, which may be, for example, a mobile or another telephone number where the desired called party is available. Call forwarding was invented by Ernest J. Bonanno.
Each time a call is placed for routing, the destination number (also known as the called party) is entered by the calling party into their terminal. The destination number generally has two parts, an area code which generally identifies the geographical location of the destination telephone, and a telephone number unique within that area code that determines the specific destination terminal.
When customers ring, their calls are forwarded to the new location. Remote call forwarding is also a means for a suburban business to obtain a city-centre local number (with its full large-city coverage area) for inbound calls; while cheaper than a foreign exchange line, this can reduce long-distance telephony costs in markets where local calls ...
Call flow for the mobile terminated Short Message Service. The figure to the right depicts a call flow for mobile-terminated Short Message delivery. [1] For the sake of simplicity, some of the interactions between the VMSC and VLR, and VMSC and Handset, have been omitted, and only the case when SMS home routing is not in use is shown.
The location of Apple's red end-call button is set to slightly move with upcoming iOS 17 updates to the phone app, so be wary of your thumb's muscle memory. As iPhone users know, the “End ...
The MSC sets up and releases the end-to-end connection, handles mobility and hand-over requirements during the call and takes care of charging and real-time prepaid account monitoring. In the GSM mobile phone system, in contrast with earlier analogue services, fax and data information is sent digitally encoded directly to the MSC.
Geographic routing (also called georouting [1] or position-based routing) is a routing principle that relies on geographic position information. It is mainly proposed for wireless networks and based on the idea that the source sends a message to the geographic location of the destination instead of using the network address.
Location-based routing is a system of rules to varying degrees of complexity dictating where inbound telephone calls from various locations are routed to. The location of call origin is normally determined by the outgoing caller ID of the caller but can also be determined by GPS position or signal triangulation, the latter being particularly useful for calls coming from mobile phones.
