6、y Set 4: SCF-SCF interface Summary The Q.1248.x family of ITU-T Recommendations defines the Intelligent Network (IN) Application Protocol (INAP) for IN Capability Set 4 (IN CS-4). This definition is based upon IN CS-3 ITU-T Q.1238 (2000) and upon the general rules for INAP provided in ITU-T Q.1208,
7、and is consistent with the scope of IN CS-4 as defined in ITU-T Q.1241. Within the Q.124.x series of ITU-T Recommendations, the Q.1248.x family of ITU-T Recommendations describes the protocol realizing the Q.1241 Distributed Functional Plane in a service and vendor implementation independent manner,
8、 as constrained by the capabilities of the embedded base of network technology. This provides the flexibility to allocate distributed functionality into multiple physical network configurations and to evolve IN from IN CS-4 to some future CS-N. This Recommendation belongs to the Q.1248.x family of I
9、TU-T Recommendations for IN Capability Set 4. It covers the SCF-SCF interface including the description of the aspects of the SCF Functional Entity which are relevant to this interface. This Recommendation includes an electronic attachment containing Annex A, ASN.1 definitions. Source ITU-T Recommen
10、dation Q.1248.6 was prepared by ITU-T Study Group 11 (2001-2004) and approved under the WTSA Resolution 1 procedure on 13 July 2001. Keywords Intelligent Network, INAP ii ITU-T Rec. Q.1248.6 (07/2001) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency i
11、n the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basi
12、s. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolu
13、tion 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration a
14、nd a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of c
15、laimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Rec
16、ommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.
