+ | =====GTP Flow===== | ||
+ | GTP (GPRS Tunneling Protocol) is a group of IP-based connection protocols used in GSM, UMTS, and LTE networks. | ||
+ | The GTP protocol is used by mobile operators as a tunnel for data transmission. It consists of two layers: | ||
+ | * **GTP-C** (Control Plane) — service information, | ||
+ | * **GTP-U** (User Plane) — user data, such as voice information. | ||
+ | DPI decodes **GTP-C**, and this information is sent to **IPFIX** in the “GTP flow” and “Raw GTP flow” reports in the GUI. | ||
+ | |||
+ | GTP logs are used for the following tasks: | ||
+ | * **Base station load analysis**: distribution of subscribers across base stations and traffic monitoring, which is useful for LBS (Location-Based Services). | ||
+ | * **Anomaly monitoring**: | ||
+ | * **Subscriber tracking** on the map and movement analysis: visualization on the map is possible, as well as route analysis and current location. | ||
+ | Some operators also use GTP logs to link IP and IMSI (subscriber identifier) to consolidate user information from various information systems (DPI, billing, etc.). | ||
+ | |||
+ | The report is based on versions **GTP-C V1** and **GTP-C V2**. | ||
+ | Access to GTP Log is available only to users with a QoE Standard license. [[en: | ||
