Burst parameter: parameter indicating the absolute ma
33、ximum number of UUS 3 service related user information messages that can be sent at intervals indicated by the value 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 subscr
34、iber activates the UUS supplementary service. For service 3 the remote subscriber 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: subscriber who has a provision of the UUS s
35、upplementary 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 Serving network: network of the served subscriber User-to-User Info
36、rmation (UUI): information transferred by using the UUS supplementary service ETSI ETSI TS 123 087 V14.0.0 (2017-04)73GPP TS 23.087 version 14.0.0 Release 14UUS Service: UUS services (Service 1, 2 and 3) are components of the UUS supplementary service. If the UUS supplementary service is provided to
37、 a subscriber, he can handle the UUS services independently within a call 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: ACM Address Complete Message ANM ANswer Message CON CONnectCPG Call ProGress IAM Initial Address Message MS Mobile Station REL RELe

39、l The UUS supplementary service allows the transfer of UUI to a remote subscriber over the signalling channel in association 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 Ca
40、ll Control messages. The UUS Service 2 allows the transfer of UUI with a specific User-to-user message after the served 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
41、 message during an active call. For the use of the UUS supplementary service in GSM PLMNs the support of UUS capabilities 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 Ser
42、vices 1, 2 or 3 shall be used within a call, the UUS capabilities have to be activated by the served subscriber either 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 o
43、r an explicit request. UUS Service 1 can be requested either implicitly or explicitly. Service 2 and 3 can only be 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 th
44、e received UUI transparently to the B-side. For the purpose of UUS service 1 implicitly requested, no explicit check 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 requ
45、ested, the network shall transfer all UUI contained in call control messages. If the calling subscriber has UUS1 not provisioned, the contained UUI shall be discarded by the serving MSC. The call shall be established without further restrictions. ETSI ETSI TS 123 087 V14.0.0 (2017-04)83GPP TS 23.087
46、 version 14.0.0 Release 14The served subscriber shall not be informed whether the implicit request was successful or not. 4.1.2 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
47、 3 can be activated during an established call with a Facility message. A UUS Service 1 request can be accompanied 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
48、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 th
49、is UUS Service is received from the remote side. Service 3 can be explicitly activated during an active call by both parties. This may lead to a collision of activation requests. The collision of activation requests occurs when there is an outstanding request for service 3 and a subsequent request is received from the remote user. The entity (user or network) that observes the collision shall reject the second request with Facility message. This leads to the rejection of both requests. 4.1.3 UUS required option As an option at call set-up the served subscri
