Foreword This ETSI Guide (EG) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). The present document is part 4 of a multi-part deliverable covering Service Provider Access; Ope
15、n Service Access for API requirements, as identified below: Part 1: “Version 1“; Part 2: “Version 2“; Part 3: “Version 3“. Part 4: “Version 4“. Introduction The present document contains the Requirements capture for ETSI 4.0 “Third Party API“ protocol specification: ES 203 915 series 1 and ES 202 39
16、1 series 2.ETSI ETSI EG 201 988-4 V1.1.1 (2008-02) 5 1 Scope The present document contains the functional requirements for Open Service Access Requirements Version 4.0. The present document has been compiled in conjunction with Parlay and represents the sixth phase of the Parlay API. The ETSI and Pa
17、rlay API have been specified and designed using the requirements identified both in the previously published Parts of this specification, Parts 1 through 3 and in the present document, Part 4. The requirements are intended to provide the necessary functionality for benchmark applications. It is the
18、intention that the new requirements should build upon the ETSI Phase 3.0 API and that of the Parlay 5.0 specification requirements, as described in EG 201 988-3 3, and should be fully backward compatible. This means that any network operator implementing ETSI Phase 4.0 or Parlay 6.0 should be able t
19、o interwork with a client application provider implementing ETSI Phase 3.0 or Parlay 5.0. In other words ETSI Phase 4.0 and Parlay 6.0 will retain ETSI Phase3.0 and Parlay 5.0 as a complete subset. A full description of backward compatibility considerations is presented in clause 9 of ES 203 915-1 4
20、. For any requirement that would result in an extension of, or would build upon, a part of the API specification set that is published jointly by 3GPP as well, in addition to ETSI and Parlay, the contributing companies are encouraged to submit their requirements to the 3GPP SA1 requirements process

32、nd extensible interface into networking technologies. The Parlay API is therefore applicable to a number of business and application domains, not just telecommunications network operators. Examples of business domains that may use the API include: Third Party NGN Service Providers. Interactive Multi
33、media Service Providers. Corporate Businesses. Small Businesses. Residential Customers. Network Operators. All of these businesses have networking requirements, ranging from simple telephony and call routing to call centres, virtual private networks and fully interactive multimedia. ETSI ETSI EG 201
34、 988-4 V1.1.1 (2008-02) 7 4.1 Requirements on interfaces at different levels of abstractions As originally defined in clause 6.5 of EG 201 988-3 3, the OSA-defined functions may be accessed through interfaces at different levels of abstractions and according to different programming formalisms, in a
35、ddition to those defined in the previous Releases. Accordingly, ETSI Phase 3.0 and Parlay 5.0 is realized in two specifications sets: OSA APIs (Parlay 5). OSA Parlay X 2 Web Services. For ETSI Phase 4.0 and Parlay 6.0, the requirements described in the present document will likewise be realized in t
36、wo specifications sets: OSA APIs (Parlay 6): i.e. ES 203 915 series 1. OSA Parlay X Web Services: i.e. ES 202 391 series 2. Guidelines have been adopted to determine which of the two abstraction layers provides the appropriate domain to realize the requirements described in the present document. 4.2
37、 Parlay X Web Service Guidelines The interfaces represented by the Parlay X Web Services should be powerful yet simple and highly abstracted. The following rules serve as guidelines for realizing requirements using Parlay X Web Services. Exceptions to these rules will be considered if they are justi
38、fied by simplicity or completeness of the API, and if the resulting specification is sufficiently differentiated from related specifications. A Parlay X Web Service specification will be a functional abstractions of a Parlay/OSA specification. Where a functionally overlapping Parlay/OSA specificatio
39、n exists, the Parlay X Web Service specification will be an abstraction of the Parlay/OSA specification. Parlay X Web Service specifications should offer a coarser granularity level (e.g. measured as the relative size, level of detail, or depth of penetration), and contain less than half the methods
40、 of the equivalent Parlay/OSA specifications. Parlay X Web Service specifications should not mandate the maintenance of state. Parlay X Web Service specifications should not contain asynchronous message exchange, but often include event notification. Parlay X Web Service specifications should never
41、imply detailed protocol knowledge. Parlay X Web Service specifications should be functionally self-contained from the developers point of view. For any Parlay X Web Service specification, 80 % of the above rules should be met. 5 Proposed enhancements to existing Interfaces 5.1 General requirements 5

ETSI ETSI EG 201 988-4 V1.1.1 (2008-02) 8 5.1.2 Backwards Compatibility/Deprecation - Parlay X Web Services For OSA Parlay X 3 Web Servic
43、es it is desirable, but it is not considered necessary, to retain backwards compatibility with the existing OSA Parlay X 2 Web Services specifications. This is because the existing specifications are immature and there are limited implementations and deployments to date. This provide an opportunity
44、to correct identified shortcomings, and in so doing provide a solution approach that will enable a richer set of applications whilst being application agnostic in nature. 5.2 Call Session Control Issues and Motivation: Operators and vendors desire to extend the call control capabilities of the Parla
45、y X Web Services. The suggested approach to the evolution of Parlay X Call Control builds on the agreed view of keeping the Parlay X web services true to the design goal of “Separation of Concerns“ and to avoid bundling of functionality where possible. This approach is not backward compatible with t
46、he existing Parlay X Call control-related web services, but this is an acceptable trade-off as noted in clause 5.1.2. Requirements Description: Call Participant Control. The ability to add, remove, transfer call participants, for either application or network initiated calls. IVR Interaction. Applic
47、ation should be able to request IVR Interaction on a call. It should include simple Play Announcement and Play and Collect information capabilities for both network and application initiated calls. Additional Call Notification events. The following are specifically identified: - Call Progress. - Cal
48、l Setup failure. - Call Party Disconnect. - Call Party Answer. - Call Rejected. - Media Changed. Deassign Call Control. The ability to stop an application from receiving notifications on a specific call. Media Control. The ability to manipulate the media on either an application or network initiated
49、 call. Proposed Solution and Further Considerations: These functions are currently implemented in the Parlay/OSA APIs. These functions are also viewed as appropriate for implementation at an abstraction level consistent with that of the Parlay X Web Services. Figure 1 shows the conceptual principles of how the involved call control elements relate.
