25、 Technical Specification gives the stage 3 description of the User-to-User signalling supplementary services. The User-to-user supplementary service is divided into 3 different services: - Service 1 (UUS1) - Service 2 (UUS2) - Service 3 (UUS3) 2 References The following documents contain provisions

30、ich the served subscriber activates the UUS supplementary service. For service 3 the remote party can be either the called or the calling party of an established call to whom the use of the UUS supplementary service is requested by the served subscriber. Served subscriber: The subscriber who has a p
31、rovision of the UUS supplementary service and who activates the UUS supplementary service. For service 1 and 2 the served subscriber is always the calling subscriber, for service 3 either the calling or the called subscriber can be the served subscriber. User-to-User Information (UUI): The informati
32、on transferred by using the UUS supplementary service. UUS not required: If the “UUS not required“ indication is given by the subscriber, the call will be completed even if UUI cannot be passed to the called subscriber. UUS required: If the “UUS required“ indication is given by the subscriber, the c
33、all shall not be completed if UUI cannot be passed to the called subscriber. UUS Service: The UUS services (Service 1, 2 and 3) are components of the UUS supplementary service. If the UUS supplementary service is provided to a subscriber, he can handle the UUS services independently within a call. E

36、r side 4.1 UUS1 For UUS1, both parties may exchange UUI during the set-up and the clearing phases of a call by including User-user information element(s) in basic call control messages (ALERTING, CONNECT, DISCONNECT, PROGRESS, RELEASE, RELEASE COMPLETE, SETUP). UUS1 can be activated implicitly or ex
37、plicitly. When UUS1 has been activated, either subscriber may include UUI when accepting, rejecting or terminating the call. UUS1 is automatically deactivated when the call is cleared. ETSI ETSI TS 124 087 V15.0.0 (2018-07)73GPP TS 24.087 version 15.0.0 Release 154.1.1 Operation when implicitly acti
38、vated To activate UUS1 implicitly, the MS A shall include a User-user information element in the SETUP message as part of a normal call request. See 3GPP TS 24.008. Implicitly activated UUS1 is active for the duration of the call; i.e. the remote party is not required to send a response to the impli
39、cit activation request. However, the remote party may include a User-user information element in the call response. The served subscriber or the remote party may terminate the call before a connection is established. MS A NETWORK SETUP - User-user . ALERTING User-user (Note 1), (Note 2) Figure 1: UU

NOTE 2: Under normal conditions DISCONNECT message is used for clearing the call, but also RELEASE or RELEASE COMPLETE message may be used as the first call clearing message. 4.1.2 Operation when explicitly activated
41、 UUS1 is explicitly requested by the MS A when including a Facility information element with a UserUserService invoke component in the SETUP message. See 3GPP TS 24.008, 3GPP TS 24.080. The UserUserService invoke component shall indicate whether the service is “UUS required“ or “UUS not required“. I
42、f the remote party accepts the request, the network shall include a Facility information element with a UserUserService Return Result component in the ALERTING or the CONNECT message sent to the MS A. If the request is not accepted, the network shall include a Facility information element with a Use
43、rUserService Return Error component in the DISCONNECT message (when UUS required) or in the ALERTING or in the CONNECT message (when UUS not required) sent to the MS A. See errors in 3GPP TS 24.080. An explicit activation request may include UUI. The network may include User-user information element
44、 when accepting the activation request. The served subscriber or the remote party may terminate the call before a connection is established. For UUS1 explicit activation SS Version Indicator value 3 or above has to be used. ETSI ETSI TS 124 087 V15.0.0 (2018-07)83GPP TS 24.087 version 15.0.0 Release
