The present document defines the group call communication of interworking at the Inter-System Interface (ISI) for Terrestrial Trunked Radio system (TETRA) supporting Voice plus Data (V+D). The TETRA V+D interworking – basic operation part defines the interworking between TETRA networks over the corresponding interface: the Inter-System Interface (ISI). It comprises the following sub-parts: • Transport Layer Independent Specification ISI general design [2]; • General Design, PSS1 over E.1 [i.7]; • General Design, SIP/IP [i.8]; • Transport Layer Independent Additional Network Feature – ISI Individual Call (ANF-ISIIC) [3]; • Transport Layer Independent Additional Network Feature Group Call (ANF-ISIGC) (the present document); • Transport Layer Independent Additional Network Feature Short Data service (ANF-ISISD) [i.9]; • Transport Layer Independent Additional Network Feature Mobility Management (ANF-ISIMM) [4]; • Generic Speech Format Implementation [i.10]. The present document is the ANF-ISIGC sub-part 3-13. In analogy with Recommendation ITU-T I.130 [i.3], the stage one, stage two and stage three of the three level structure is used to describe the TETRA Inter-System Interface services as provided by European Private or Public Trunked Radio System operators:
