• To design and maintain 3GPP Applications (including USIM and ISIM) to support 3GPP security requirements;
• To maintain the 3GPP SIM Application
• To provide capabilities for service creation (e.g. evolution of USIM Application Toolkit, APIs);
• To specify download mechanisms for applications;
• To specify the 3GPP applications as part of a multi application card in a single/multi card reader terminal environment;
• To maintain current service capabilities and develop new services, maintaining backwards compatibility;

Liaisons

• With ETSI Project SCP for the interface with the standard smart card platform;
• With other groups as required (e.g. 3GPP2, OMA, GSMA).
