CDRs are sent in GTP' messages, or saved in files and fetched with FTP protocol. Information on chargeable events includes time of call set-up, duration of the call, amount of data transferred, etc. A separate CDR is generated for each party to be charged. Entries on CDRs use a {category, usage} syntax.
GPRS Tunnelling Protocol (GTP) is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS, LTE and 5G NR radio networks. In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points. GTP can be decomposed into separate protocols, GTP-C, GTP-U ...
For GTP' v2, this has a value of 2 (hence the name GTP' v2). Protocol Type (PT) a 1-bit value that differentiates GTP' (value 0) from GTP (value 1). Reserved a 3-bit reserved field (must be 1's). Header Length (Hdr len) a 1-bit value that for GTP' version 0 indicates if using a 20 byte header (value 0) (as per GTP) or this 6 byte header. This ...
A call detail record (CDR) is a data record produced by a telephone exchange or other telecommunications equipment that documents the details of a telephone call or other telecommunications transactions (e.g., text message) that passes through that facility or device. The record contains various attributes of the call, such as time, duration ...
GPRS Tunnelling Protocol is the defining IP-based protocol of the GPRS core network. Primarily it is the protocol which allows end users of a GSM or WCDMA network to move from place to place while continuing to connect to the Internet as if from one location at the Gateway GPRS support node (GGSN).
Format change and call detail record normalization; Business transformation of data; In a telecom billing scenario, mediation is the first step after receiving a call detail record. The mediated call detail record files are forwarded to a rating engine, which calculates the charge associated with the call detail records.
Content Disarm & Reconstruction (CDR) is a computer security technology for removing potentially malicious code from files. Unlike malware analysis , CDR technology does not determine or detect malware's functionality but removes all file components that are not approved within the system's definitions and policies.
System Architecture Evolution (SAE) is the core network architecture of mobile communications protocol group 3GPP's LTE wireless communication standard.. SAE is the evolution of the GPRS Core Network, but with a simplified architecture; an all-IP Network (AIPN); support for higher throughput and lower latency radio access networks (RANs); and support for, and mobility between, multiple ...
