The present document defines the stage 1 description of the call hold supplementary service (SS-HOLD) for the Terrestrial Trunked RAdio (TETRA) as provided by European operators. The stage 1 description is an overall service description from the user point of view but does not deal with the details of the human interface itself (see ITU-T Recommendation I.130 [1]). SS-HOLD enables a user to interrupt communication on an existing individual call and then subsequently, if desired, re-establish communication. The present document specifies the service description of the supplementary service and the procedures to be expected with successful and unsuccessful outcomes. In addition the present document specifies the interactions with other TETRA supplementary services and Interworking considerations. Charging principles are outside the scope of the present document.

ETSI EN 300 396-3 V1.2.1 (2004-12)

The multi-part deliverable EN 300 396 defines the TErrestrial Trunked RAdio (TETRA) Direct Mode Operation (DMO). It specifies the basic air interface, the inter-working between Direct Mode (DM) groups via repeaters, and inter-working with the TETRA Voice plus Data (V+D) system via gateways. It also specifies the security aspects in TETRA DMO, and the intrinsic services that are supported in addition to the basic bearer and teleservices. The present document applies to the TETRA DMO Mobile Station - Mobile Station (MS-MS) air interface and contains the specifications of the Data Link Layer (DLL) and the network layer according to the ISO model. It establishes the services, messages and protocols used for voice and circuit mode data calls and short data transfer, starting with the upper layers:
- it defines and specifies the protocol used by the layer 3 entity to communicate across the air interface;
- it defines and specifies the services and protocol used in the DLL.
The normative annexes mainly specify the parameter values used in the protocol.

ETSI EN 300 392-12-22 V1.3.1 (2005-04)

The present document defines the stage 3 specifications of the Supplementary Service Dynamic Group Number Assignment (SS-DGNA) for the Terrestrial Trunked Radio (TETRA). The SS-DGNA enables a user to dynamically define group identities and group related parameters to the TETRA system and to the subscribers in the system. These definitions are used to enable group call invocations to dynamically defined groups. The SS-DGNA specification defines the creation, modification, deletion and interrogation of group definitions in the Switching and Management Infrastructure (SwMI), in the Mobile Station (MS). The present document does not include the specification for access priority used for random access in uplink and call priority used by SwMI for resource allocation in a group call. Access priority and call priority can be specified and applied for groups using Supplementary Services Access Priority (SS-AP), Priority Call (SS-PC) and Pre-emptive Priority Call (SS-PPC). Thus, the definition procedure of these priorities is outside the scope of the present document. Man-Machine Interface (MMI) and charging principles are also outside the scope of the present document. Supplementary service stage 3 specification is preceded by the stage 1 and the stage 2 specifications of the service. Stage 1 describes the functional capabilities from the user's point of view. Stage 2 defines the functional behaviour in terms of functional entities and information flows. Stage 3 gives the precise description of the supplementary service from the implementation point of view. It defines the protocols for the service and the encoding rules for the information flows. It defines the processes for the functional entities and their behaviour. The described protocols and their behaviour apply for the SwMI and for the MS and can be applied over the Inter-System Interface (ISI) between TETRA systems.

Terrestrial Trunked Radio (TETRA); Subscriber Identity Module to Mobile Equipment (SIM-ME) interface; Part 3: Integrated Circuit (IC); Physical, logical and TSIM application characteristics
ETSI EN 300 812-3 V2.2.1 (2004-02)

The present document defines the interface between the Subscriber Identity Module (SIM) and the Mobile Equipment
(ME) for use during the network operation phase of TETRA as well as those aspects of the internal organization of the
SIM which are related to the network operation phase. This is to ensure interoperability between a SIM and a ME independently of the respective manufacturers and operators. The concept of a split of the MS into these elements as well as the distinction between the TETRA network operation phase, which is also called TETRA operations, and the administrative management phase is described in the User Requirement Specification ETR 295 [6].
The present document defines:
• the requirements for the physical characteristics of the SIM, the electrical signals and the transmission protocols;
• the model which shall be used as a basis for the design of the logical structure of the SIM;
• the security features; This edition of the standard covers the security mechanisms for ITSI based services including authentication and OTAR for keys addressed to an ITSI;
• the interface functions;
• the commands;
• the contents of the files required for the TETRA application;
• the application protocol.
The present document does not specify any aspects related to the administrative management phase. Any internal technical realization of either the SIM or the ME are only specified where these reflect over the interface. The present document does not specify any of the security algorithms which may be used.
The physical SIM described in the present document is a removable Integrated Circuit (IC) card. The SIM is an optional device within TETRA MSs. The present document does not preclude the implementation of fully functional MSs without a SIM. All references to mobile equipment in the present document are to be taken to mean mobile equipment which have been designed to operate with a SIM.
The present document deals with all aspects of trunked mode MS operation. For direct mode MS operation key user operation is supported by the SIM but not key holder or key generator operation. Furthermore, storage of information for direct mode MS operation in repeater and gateway mode are supported, but any extra storage required in the direct mode repeater or direct mode gateway terminals themselves is not supported.
