GSM Centric SS7/C7 and Mobile Application Part (MAP) Training

In fixed line telecommunications systems, the location of the calling and called parties is derived from the numbering scheme adopted in the network. However in wireless systems the situation is different because a subscriber can roam across the coverage areas, which in the case of GSM/DCS are multiple countries typically. For incoming mobile calls there is no direct translation between the number of the mobile handset and the location of the customer. Procedures are therefore required to determine the location of a called customer on a real-time basis to allow delivery of incoming calls.

MAP provides core cellular network functionality - for example the functionality to route calls to and from mobile subscriber or messaging be it Short Message Service (SMS), Enhanced Messaging Service (EMS) or Multimedia Messaging Service (MMS). The US version is known as ANSI41-MAP. The international version is known as GSM-MAP.

The course is delivered by Lee S Dryburgh lead author of Signaling System No. 7 (SS7/C7): Protocol, Architecture, and Services (Networking Technology).
