27、l 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
28、). 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 ou
29、tcomes. 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. 2 References The following documents contain provisions which, through reference in this tex
30、t, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. Referen

36、 SS is only used when referring to a specific supplementary service. 4 SS-HOLD stage 1 specification 4.1 Description 4.1.1 General description The call hold supplementary service (SS-HOLD) enables a user to interrupt an existing individual call and then subsequently retrieve that call (in re-establi
37、shing communication), unless it has been cleared. 4.1.2 Qualifications on applicability to telecommunication services 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-HO
38、LD 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 The supplementary service shall be withdrawn by the service provider: for administrative purposes; or at the request of the served user, if individually provided.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
39、then be given to the subscribers by the network. 4.2.2 Normal procedures 4.2.2.1 Activation/deactivation, interrogation 4.2.2.1.1 Activation/deactivation The service shall be activated upon provision and deactivated upon withdrawal. ETSI ETSI EN 300 392-10-12 V1.3.1 (2004-02) 9 4.2.2.1.2 Interrogati
40、on The network and the served user may support the interrogation procedure, initiated by the served user to inform him about: the number of calls put on hold by that user; the calls presently on hold. 4.2.2.2 Invocation and operation 4.2.2.2.1 Hold request When the served user invokes SS-HOLD during
41、 an individual call, after it has been established, and the network accepts that invocation, the call shall be interrupted. The network shall inform the served user about the success of that invocation. It shall also notify the affected user about it. If the served user uses a radio access to the ne
42、twork (i.e. he is equipped with mobile terminal equipment), the corresponding air interface resource used for the call traffic may be released. If the affected user uses a radio access to the network, it is an implementation matter whether the network releases or not the corresponding air interface
43、resource used for the call traffic (on the affected user side). The served user may be either of the two users participating in the individual call. If the supplementary service is provided to both users, each one can put the call on hold independently of the other. The served user may be able to in
44、voke SS-HOLD for more than one individual call. However, the maximum number of held calls at any one time per subscriber shall be a network option. 4.2.2.2.2 Follow-up When the served user has successfully invoked SS-HOLD he shall still be considered by the network as being in the basic call state:
45、call active. The same shall apply for the affected user. NOTE 1: More generally, except if the network releases the air interface resource used for the call traffic on the affected user side, no change happens in the basic (individual) call for the affected user when it is put on hold for the served
46、 user. After he has successfully invoked SS-HOLD, the served user shall be able to make another request to the network in order to: retrieve that call from hold or any other call which is on hold; originate a new call; establish connection to an incoming call, e.g. a waiting call. If the network can
47、 satisfy the request (i.e., in the case of mobile terminal equipment, air interface and other necessary resources are available), it shall re-establish the call and acknowledge that request in indicating that the call has been (successfully) retrieved; if it cannot, it shall reject the request and i
48、nform the served user whether or not the call on hold is retrievable, i.e. whether or not a new retrieval request sent later may be successful. If the call on hold is retrievable but cannot be retrieved, e.g. because resources are not available at this time, such reject may be delayed for some pre-d
49、efined time. The served user may then subsequently ask for another retrieve request for the call on hold. NOTE 2: Unless the call has been cleared in the meantime or congestion (e.g. at the air interface) occurs, one might expect that the network will able to fulfil the retrieval request if: square4 the served user has not changed location since he has put that call on hold; or if square4 the served user has changed location since he has put that call on hold and both his terminal equipment and the network support the optional SS-HOLD location ch
