Burst parameter: parameter indicating the absolute maximum number of UUS 3 service related user information messages that can be sent at intervals indicated by the val
35、ue of timer T2-UUS3 Remote network: network of the remote subscriber Remote subscriber: for service 1 and 2 the remote subscriber is the called party of a call to which the served subscriber activates the UUS supplementary service. For service 3 the remote subscriber can be either the called or the
36、calling party of an established call to whom the use of the UUS supplementary service is requested by the served subscriber Served subscriber: subscriber who has a provision of the UUS supplementary service and who activates the UUS supplementary service. For service 1 and 2 the served subscriber is
37、 always the calling subscriber, for service 3 either the calling or the called subscriber can be the served subscriber Serving network: network of the served subscriber User-to-User Information (UUI): information transferred by using the UUS supplementary service UUS Service: UUS services (Service 1
38、, 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 ETSI ETSI TS 123 087 V15.0.0 (2018-07)73GPP TS 23.087 version 15.0.0 Release 153.2 Abbreviations For the purposes of th

40、ngUUS1 User-to-User Signalling Service 1 UUS2 User-to-User Signalling Service 2 UUS3 User-to-User Signalling Service 3 Further GSM related abbreviations are listed in GSM 01.04. 4 General The UUS supplementary service allows the transfer of UUI to a remote subscriber over the signalling channel in a
41、ssociation with a call to this subscriber. The UUS supplementary service is divided in Service 1, Service 2 and Service 3. The UUS Service 1 allows the transfer of UUI embedded within Call Control messages. The UUS Service 2 allows the transfer of UUI with a specific User-to-user message after the s
42、erved subscriber has received an address complete indication and prior to the answer indication from the B-side. The UUS Service 3 allows the transfer of UUI with a specific User-to-user message during an active call. For the use of the UUS supplementary service in GSM PLMNs the support of UUS capab
43、ilities within the inter-exchange signalling system (e.g. ISUP) is necessary. However this is out of scope of the present document. 4.1 Activation of UUS components If any of the UUS Services 1, 2 or 3 shall be used within a call, the UUS capabilities have to be activated by the served subscriber ei
44、ther when initiating this outgoing call (Service 1, 2 and 3) or during an established call (Service 3). The UUS capabilities for a call can be requested by means of an implicit request or an explicit request. UUS Service 1 can be requested either implicitly or explicitly. Service 2 and 3 can only be
45、 requested explicitly. 4.1.1 Implicit request The UUS1 service is activated implicitly by the presence of UUI in the set-up request from the mobile station. The network shall transfer the received UUI transparently to the B-side. For the purpose of UUS service 1 implicitly requested, no explicit che
46、ck for the availability of UUS capabilities at the destination network has to be performed by the originating network. If the calling subscriber has UUS 1 provisioned and implicitly requested, the network shall transfer all UUI contained in call control messages. If the calling subscriber has UUS1 n
47、ot provisioned, the contained UUI shall be discarded by the serving MSC. The call shall be established without further restrictions. The served subscriber shall not be informed whether the implicit request was successful or not. ETSI ETSI TS 123 087 V15.0.0 (2018-07)83GPP TS 23.087 version 15.0.0 Re
48、lease 154.1.2 Explicit request Any UUS Service can be explicitly activated by the served subscriber within the set-up request initiating a mobile originated call. In addition UUS Service 3 can be activated during an established call with a Facility message. A UUS Service 1 request can be accompanied
49、 by appropriate UUI. The network shall check for the availability of UUS capabilities for the call by passing the UUS request and the eventually accompanied UUI to the remote side. If a UUS Service is available for the call an appropriate “UUS provided“ indication for this UUS Service shall be sent within the first backward message from the remote side. A UUS Service shall not be activated for the call if a “UUS not provided“ indication or no indication about the availability of this UUS Service is received from the remote side. Service 3 can be explicitly act
