ETSI ETSI TS 123 090 V14.0.0 (2017-04)53GPP TS 23.090 version 14.0.0 Release 141 Scope The present document gives the stage 2 description of Unstructured Supplementary Service Dat

23、a (USSD). The unstructured supplementary service data (USSD) mechanism allows the Mobile Station (MS) user and a PLMN operator defined application to communicate in a way which is transparent to the MS and to intermediate network entities. The mechanism allows development of PLMN specific supplement

24、ary services. The following diagram shows how handling of USSD is carried out, independently of the applications. Figure 1.1: Handling of USSD The present document defines the requirements for handling USSD at the MS and network entities. It does not include specification of particular applications,

25、 nor does it specify how a particular application is selected. Where more than one application exists at a network entity, routing of messages to the correct application is carried out by the USSD handler. The MMI for USSD is specified in TS 22.030 and TS 22.090. The alphabet indicator and the data

26、coding scheme are defined in TS 23.038. USSD may be initiated by the MS user, or by the network in the following ways: - Network initiated USSD (clause 1); - Mobile initiated USSD (clause 2). 2 References The following documents contain provisions which, through reference in this text, constitute pr

27、ovisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies. In the case of a re

28、ference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR 21.905: “3G Vocabulary“. 2 3GPP TS 22.030: “Man-Machine Interface (MMI) of the User Equipment (UE)“. 3 3GPP

30、t are listed in TR 21.905 1. AI Application Initiated MI Mobile InitiatedUSSD Unstructured Supplementary Service Data 4 Cross phase compatibility The Phase 1 series of GSM specifications defined the signalling protocol which may be used, but they did not specify the operation of USSD as a service. T

31、he main body of the present document assumes that the MS and all network entities comply with this phase of USSD. In order to minimize any possible problems between a Phase 1 implementation of USSD and this phase, subclauses 5.6 and 6.6 define the additional requirements for when one or more entity

32、complies with the Phase 1 USSD specification for network initiated and mobile initiated USSD respectively. 5 Network initiated unstructured supplementary service 5.1 Handling of network initiated USSD The network (MSC, VLR or HLR) can at any time send a USSD operation towards an MS. This operation m

33、ay be either a request (asking the MS to provide information) or a notification (requiring no information in the response from the MS). No prior provision of USSD is required, although provision of services which make use of USSD may be required. All USSD requests, notifications and responses (excep

34、t responses to notifications) contain the USSD string, an alphabet indicator and language indicator. 5.2 Functions and information flows The following text describes the handling of network initiated USSD. Diagrammatic representations are as follows: Figure 5.1 SDL for USSD invocation (HLR, VLR, MSC

35、); Figure 5.2 SDL for forwarding of USSD operations (VLR, MSC); Figure 5.3 SDL for MS; Figure 5.4 Information flow for successful single USSD request; Figure 5.5 Information flow for successful single USSD notification; Figure 5.6 Information flow for successful multiple USSD requests; Figure 5.7 In

36、formation flow for failed USSD request. 5.2.1 Invoking unstructured SS operation from the HLR When an application in the HLR is to send a USSD request or notification to an MS, it shall set up a transaction to the VLR where the subscriber is currently registered and send the operation to the VLR. It

37、 shall then await a response. The HLR is responsible for controlling the transaction, and shall therefore normally release the transaction when it receives a response from the VLR. The HLR may also release the transaction before receiving a response if necessary (e.g. if an application timer expires

38、). If an application in the HLR needs to send further operations to the same MS as part of the same application, it may continue to use the same transaction until all operations are completed (see figure 5.6). If a different transaction is to be used for a subsequent operation, the HLR shall release

39、 the first transaction before starting the next. ETSI ETSI TS 123 090 V14.0.0 (2017-04)73GPP TS 23.090 version 14.0.0 Release 14If the VLR releases the transaction at any time (e.g. due to user clearing), the HLR shall inform the application and terminate the USSD operation. See subclause 5.2.4 for

40、forwarding of an HLR invoked operation by the VLR and MSC. 5.2.2 Invoking unstructured SS operation from the VLR When an application in the VLR is to send a USSD request or notification to an MS, it shall set up a transaction to the MSC where the subscriber is currently registered and send the opera

41、tion to the MSC. It shall then await a response. The VLR is responsible for controlling the transaction, and shall therefore normally release the transaction when it receives a response from the MSC. The VLR may also release the transaction before receiving a response if necessary (e.g. if an applic

42、ation timer expires). If an application in the VLR needs to send further operations to the same MS as part of the same application, it may continue to use the same transaction until all operations are completed. If a different transaction is to be used for a subsequent operation, the VLR shall relea

43、se the first transaction before starting the next. See subclause 5.2.4 for forwarding of a VLR invoked operation by the MSC. If the MSC releases the transaction at any time (e.g. due to the user clearing), the VLR shall inform the application and terminate the USSD operation. 5.2.3 Invoking unstruct

44、ured SS operation from the MSC When an application in the MSC is to send a USSD request or notification to an MS, it shall set up a transaction to the MS where the subscriber is currently registered and send the operation to the MS. It shall then await a response. The MSC is responsible for controll

45、ing the transaction, and shall therefore normally release the transaction when it receives a response from the MS. The MSC may also release the transaction before receiving a response if necessary (e.g. if an application timer expires). If an application in the MSC needs to send further operations t

46、o the same MS as part of the same application, it may continue to use the same transaction until all operations are completed. If a different transaction is to be used for a subsequent operation, the VLR shall release the first transaction before starting the next. If the MS releases the transaction

47、 at any time (e.g. due to the user clearing), the MSC shall inform the application and terminate the USSD operation. NOTE: MSC invoked USSD is only likely to be used for call related operations, where the application is controlling a call to or from the MS. 5.2.4 Forwarding USSD operations The VLR m

48、ay any time receive a USSD operation from the HLR. If the subscriber can be contacted, the VLR shall set up a transaction to the MSC and forward the operation unchanged. Any further information exchange between the HLR and MSC shall be transparent to the VLR. When one transaction is released, the VL

49、R shall release the other. The MSC may at any time receive an USSD operation from the VLR. If the subscriber can be contacted, the MSC shall set up a transaction to the MS and forward the operation unchanged. Any further information exchange between the VLR and MS shall be transparent to the MSC. When one transaction is released, the MSC shall release the other. 5.2.5 Handling of unstructured SS operation at the MS The MS may at any time receive a USSD operation (request or notification) from the MSC. If the MS receives a USSD transaction while another USSD transact
