WIRELESS EXPERTISE > GSM and GPRS

PlanetBeyond knows GSM! We know what happens in a GSM network when a subscriber switches on his mobile phone or when a subscriber places a mobile call while roaming in a foreign country network.

PlanetBeyond has studied and understood the GSM standards that define the workings of GSM mobile networks (the same principles apply to other cellular technologies) including what bearer service and tele-services are mandated, the supplementary services a subscriber should expect and how they behave when activated, the protocols that enable a call to be setup including Signaling System 7 and it’s MAP (Mobile Application Part) extension that enables a call to be routed to a mobile subscriber who may be in his home PLMN (H-PLMN) or roaming in visited PLMN (V-PLMN).

We know how to add intelligence to a mobile network as specified by the CAMEL standard and we know what CAP (Camel Application Part) messages are exchanged between the gsm-SSF and the gsm-SCF when it is discovered (through Camel Subscription information stored in the HLR) that the mobile subscriber has subscribed to an operator specific service.
