The bas

32、ide the ability for users to identify specific communication instances as UC. OBJ 2 The NGN should provide the ability to mark UC. OBJ 3 The NGN should provide the ability to react to UC. OBJ 4 The NGN should provide the ability to a user to personalize the UC profile. 4.1.2 Interoperability with ex

33、isting services OBJ 5 The NGN should provide Interoperability with existing solutions in the NGN. PUC should be interoperable with following existing supplementary services: Incoming Call Barring (White and Black list) - TS 124 611 i.7. Anonymous Call Rejection - TS 124 611 i.7.

ETSI ETSI TR 187 015 V3.1.1 (2011-05) 85 PUC functional architecture (stage 2) Figure 1: PUC functional architecture 5.1 PUC Functional Elements and Elementary Functions 5.1.1 PUC Personalization Functional (PPF) The PUC Personalization Functional Entity (PPF

36、) provides the customization of the preferences of the PUC filtering and routing-criteria, both for end-user customization and operator wide settings. It directly interacts with the PSD where this information is stored. The PPF has two interfaces: To the end-user, for personalization of his profile

37、and the operator to configure global settings. To the database, to store the PUC related information. This functionality can be integrated in existing interfaces (e.g. for the IMS case: Ut). ETSI ETSI TR 187 015 V3.1.1 (2011-05) 95.1.2 PUC Setting Database (PSD) The PUC Setting Database (PSD) contai

38、ns the settings for the PUC service for the UC identification and the UC handling. The PSD serves the PIMF for personalized identification and the PHF for routing decisions. The PSD has three interfaces: To the PPF for configuring the settings for PUC. To the PIMF to configure the personalized setti

39、ngs for UC identification. To the PHF for configure personal and global routing decisions. This FE can reuse existing functionalities (e.g. by reusing the UPSF/HSS). 5.1.3 PUC Handling Functional (PHF) The PUC Handling Functional Entity (PHF) deals as service-broker for the PIMF. It receives the com

40、munication requests from every configured interface to the underlying networks, gets the customized and personalized PUC configuration and deals with the communication between the PIMFs. Furthermore, it administrates the ratings delivered by the PIMF and takes routing decisions based on their result

41、s of the UC likelihood and customized / personalized preferences. The PHF has several interfaces: to one or several PIMF FE for identifying UC; to each supported underlying network: - e.g. in case of IMS, it could be the Isc interface. 5.1.4 PUC Identification and Marking Function (PIMF) The PUC Ide

42、ntification and Marking Function (PIMF) deals on a technical level to identify and mark UC within the PUC service. A single PIMF consists of two elementary functions for identifying and marking of the communication as unsolicited. To serve existing services, the PIF can serve as interface to existin

43、g services (e.g. supplementary subsystems) which just need a PMF to form a full PIMF. The PIMF has one interface: to the PHF to serve the request from the PUC. 5.1.4.1 PUC Identification elementary Functional (PIF) The PUC Identification Function (PIF) is by technical mean the functionality which id

44、entifies unsolicited communication (e.g. call-rate limiter). 5.1.4.2 PUC Marking elementary Functional (PMF) The PUC Marking Function (PMF) provides, in conjunction with the PIF, the marking of the identified UC. The marking is highly dependent on the PIF and is used by the PHF to calculate the risk

45、 of an incoming communication attempt as unsolicited.

46、sit NGN scenario Within this scenario, the user is connected via a transit network which has access to the communication path from the user to the service of his home NGN. The Transit NGN can apply PUC filtering by requesting his PUC service, the PHF addresses according to the routing rules the conf

47、igured PIMF modules which identify and mark the transiting communication request during its passes by. The home NGN can take the results from the signalling from the transit PUC service into account and apply additionally PIMF modules and apply a personalized handling for this UC request. A policy c

48、ooperation agreement is needed to provide a shared PUC service among these networks. ETSI ETSI TR 187 015 V3.1.1 (2011-05) 115.2.3 Mapped to home networks Figure 4: PUC in home network Within this scenario the user (CND) has a PUC service on his CNG and defines there his personalized filtering and h

49、andling of the identified unsolicited communication. The serving NGN can provide additional “pre-filtering“ of the communication and deliver the results as additional input to the PUC service hosted on the CNG. 5.2.4 Mapped to enterprise networks Figure 5: PUC in enterprise networks Within this deployment scenario, the PUC service provided by the NGN is additional.
