V1.2.1

The TETRA V+D interworking - at the Inter-System Interface (ISI) 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 General design [3];
• - General Design, PSS1 over E.1 [i.2];
• - General Design, SIP/IP [i.3];
• - Transport layer independent Additional Network Feature - ISI Individual Call (ANF-ISIIC) [i.4];
• - Transport layer independent Additional Network Feature - ISI Group Call (ANF-ISIGC) [2];
• - Transport layer independent Additional Network Feature - ISI Short Data service (ANF-ISISDS) (the present document);
• - Transport layer independent Additional Network Feature - ISI Mobility Management (ANF-ISIMM) [i.5];
• - Generic Speech Format Implementation [i.6].

The present document specifies the Additional Network Function (ANF) - Inter-System Interface (ISI) Short Data service (ANF-ISISDS) which is part of the Interworking at the Inter-System Interface (ISI) of the Terrestrial Trunked Radio system (TETRA) supporting Voice and Data (V+D). This service comprises of:

• - TETRA short message transmission over the ISI to individual and group addresses;
• - TETRA pre-defined status message transmission over the ISI to individual and group addresses.

ANF-ISISDS enables short data and status messages to be transferred between a user registered in one TETRA network to another user registered in another TETRA network, operating at the ISI of both SwMIs.

Like all other Additional Network Feature (ANF) specifications, those of ANF-ISISDS are produced in three stages, according to the method described in Recommendation ITU-T I.130 [4]. The present document contains the stage 1 and 2 descriptions of ANF ISIIC, and stage 3 description. The stage 1 description specifies the ANF as seen by its users, which are essentially the CMCE SDS entities in both TETRA networks. The stage 2 description identifies the functional entities involved in the ANF and the information flows between them. The stage 3 description of ANF ISISDS specifies its protocol
