Aldiscon Limited was a telecommunications software company founded in Dublin, Ireland, in 1988. The company supplied software products to mobile phone operators and became a leader in the supply of short message service centres (SMSC).[1]

Aldiscon invented the Short Message Peer-to-Peer (SMPP) telecommunications industry protocol for exchanging SMS messages between SMS peer entities such as short message service centres.[citation needed]

Aldiscon founders helped establish several mobile software companies based in the Republic of Ireland and in Northern Ireland, UK. Some include Aldiscon, Apion, Aepona, Anam, Ammeon, Accuris Networks and Altion.[2]

Aldiscon originally consisted of three subsidiaries: Aldiscon Telecommunications Software Systems, Ltd. based in Dublin, Ireland; Aldiscon, Inc. based in Dublin, Ohio USA; and Aldiscon Northern Ireland Ltd. based in Belfast, Northern Ireland. Following rapid expansion in the mid-1990s, the two Dublin companies were merged and renamed Aldiscon, Ltd.

Acquisition by Logica[edit]

Aldiscon was acquired by Logica Plc of London, UK in 1997 for GBP 51 million. Logica Plc was a large systems integration firm and it renamed Aldiscon the Logica Mobile Telecom Products Division. Aldiscon Northern Ireland was spun out into a separate company, Apion Ltd, and retained by the original owners. The mobile division was sold by Logica in 2007, with the new company named Acision and Aldiscon founder Larry Quinn returning to manage it.

In October 1999, acquired APiON's Wireless Application Protocol (WAP) product division. APiON shareholders received 1.3 million shares in valued at approximately £150 million (US$239 million).[3] A new spin off company, AePONA, was created at same time and retained by the original owners.
