Terrestrial Trunked Radio (TETRA); Voice plus Data (V+D); Part 10: Supplementary services stage 1; Sub-part 12: Call Hold (HOLD)

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.

For the purposes of the present document, the terms and definitions given in EN 300 392-9 [4], except for those of
affected user and served user, which are given below:
affected user: after SS-HOLD has been invoked by one of the two parties in an individual call, the other party in that
call
NOTE: If both parties in an individual call invoke SS-HOLD, both will be affected user for SS-HOLD invocation
by the other party.
served user: user who may invoke the supplementary service (i.e. request that a call be put on hold)

This supplementary service shall be applicable to all TETRA circuit mode individual teleservices and bearer services.
4.2 Procedures
4.2.1 Provision/withdrawal
The provision of SS-HOLD shall be either general for all (TETRA) individual subscribers or on a per individual
subscriber basis.
The supplementary service shall be withdrawn by the service provider:
• for administrative purposes; or
• at the request of the served user, if individually provided.
No specific information shall then be given to the subscribers by the network.
