name: DSP
full_form: Directory System Protocol
context: To enable charging of ARP subscribers for voice calls, an online charging interface between the DSP and ARP is established. The concept of voice call shall be interpreted as any Circuit-switched call, whatever the teleservice used (speech, 3.1 kHz audio, Fax, or CS data) except circuit-switched Video Telephony calls (BS 37, 64 kbit/s unrestricted digital info mode). The voice control architecture is shown in figure B.1.1. Figure B.1.1: Voice Control Architecture and Associated Functions The signaling between the Visited Network and the DSP utilizes CAP for the online CS domain charging as specified in TS 32.250 [10]. For the CAMEL option of IF#1, the signaling between the DSP and ARP also utilizes CAP for the online CS domain charging as specified in TS 32.250 [10]. For the Diameter option of IF#1, the signaling between the DSP and ARP utilizes Diameter Ro for the Voice Call Service online charging as specified in TS 32.276 [36] and utilizes the Proxy Function for mapping between CAMEL
description: The Directory System Protocol (DSP) is a network function responsible for managing directory services within the telecommunications network, including online charging interfaces for voice calls.
explanation: The context describes DSP's role in managing directory services and online charging, which are core functionalities of a network function. Its interaction with other network functions through protocols like CAP and Diameter Ro further supports this classification.
