Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z

21、where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit

ETSI ETSI TS 124 423 V8.5.0 (2012-03)53GPP TS 24.423 version 8.5.0 Release 81 Scope The present document defines a protocol used for manipulating data related to PSTN/ISDN Simulation services. The protocol is based on

23、 the eXtensible Markup Language (XML) Configuration Access Protocol (XCAP) 8. A new XCAP application usage is defined for the purpose of manipulating PSTN/ISDN Simulation services data. The common XCAP related aspects that are applicable to PSTN/ISDN services are specified in the present document. T

24、he protocol allows authorized users to manipulate service-related data either when they are connected to IMS or when they are connected to non-IMS networks (e.g. the public Internet). 2 References The following documents contain provisions which, through reference in this text, constitute provisions

25、 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 reference to a 3

26、GPP 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.

39、ulating NGN PSTN/ISDN simulation services settings The protocol described in the present document allows to manipulate settings and variables related that influence the execution of one or more PSTN/ISDN simulation services. Manipulation of supplementary services take place over the Ut interface (UE

40、 to AS), as shown in figure 1. UEUtASFigure 1: Ut interface Manipulation of services does not usually take place during real-time operation. Typically users manipulate their services configuration data prior to the invocation and execution of the service. Authentication of the user with HTTP may tak

41、e place directly at the AS, such as in figure 1, or with the support of an Authentication Proxy, such as in figure 2. The architecture for authentication is provided in TS 187 003 9 with the remark that the Network Application Function (NAF) is effectively an AS providing an NGN PSTN/ISDN simulation

42、 service in an NGN. UEUtAuthenticationProxyASUtFigure 2: Authentication proxy in the Ut interface path 5 The eXtensible Markup Language (XML) Configuration Access Protocol (XCAP) 5.1 Introduction For the purpose of manipulating data stored in an application server the XML Configuration Access Protoc

43、ol (XCAP) 8 is used. XCAP allows a client to read, write and modify application configuration data, stored in XML format on a server. XCAP maps XML document sub-trees and element attributes to HTTP URIs, so that these components can be directly accessed by HTTP 1. XCAP uses the HTTP methods PUT, GET

44、, and DELETE to operating on XML documents stored in the server. In the case of PSTN/ISDN simulation services, the data stored in a server is related to the execution of that given service. The present document defines a new XCAP Application Usage for the purpose of allowing a client to manipulate d

45、ata related to PSTN/ISDN simulation services. XCAP 8 defines two logical roles: XCAP client and XCAP servers. An XCAP client is an HTTP/1.1 compliant client. Similarly an XCAP server is an HTTP/1.1 compliant server. The XCAP server acts as a repository of XML documents that customize and modify the

46、execution of NGN PSTN/ISDN simulation services. Figure 3 depicts the XCAP architecture where an XCAP client sends an HTTP/1.1 request to an XCAP server. The server replies with an HTTP/1.1 response. ETSI ETSI TS 124 423 V8.5.0 (2012-03)83GPP TS 24.423 version 8.5.0 Release 8XCAPclientHTTP requestXCA

47、PserverHTTP responseFigure 3: XCAP architecture According to XCAP 8, each application that makes use of XCAP defines its own XCAP application usage. The present document defines an NGN PSTN/ISDN simulation services XCAP application usage in clause 6. This application usage defines the XML schema 2 f

48、or the data used by the application, along with other key pieces of information. XCAP focuses on the definition of XML documents that are compliant with the XML schema and constrains defined for a particular XCAP application usage. XCAP allows application to provide XML documents that are common for

49、 all users or XML documents that affect the service of a given user. Central to XCAP is the construction of the HTTP URI that points to particular XML document or certain components of it. A component in an XML document can be an XML element, attribute, or the value of it. 5.2 Functional entities 5.2.1 User Equipment (UE) 5.2.1.1 General The UE implements the role of an XCAP client, as described in clause 5.3.1. For systems where Generic Authentication Architecture 6 is used, the UE shall support the authentication mechan
