**Configurable Metadata Extraction in ASN**

From this page, you can **enable or disable** the following **metadata extraction options** on the **Aviz Service Node (ASN) for 5G-NSA:**

## User Information

1. **IMSI (International Mobile Subscriber Identity):** A unique identifier for a mobile subscriber.
2. **IMEI (International Mobile Equipment Identity):** A unique identifier for a mobile device.
3. **MSISDN (Mobile Station International Subscriber Directory Number):** The phone number associated with the subscriber.
4. **APN/DNN (Access Point Name / Data Network Name):** Defines the network path for data connections.
5. **USER TYPE**: Classification of the user, typically indicating subscriber type or service level.
6. **UE IP ADDR(User Equipment IP Address)**:The IP address assigned to the user's device.

## User Location Information

1. **CGI** **(Cell Global Identifier):** A unique identifier for a cell in a mobile network.
2. **SAI** **(Service Area Identifier)**: Identifies the service area within a network.
3. **RAI (Routing Area Identifier)**: Specifies the routing area within a mobile network.
4. **TAI (Tracking Area Identifier)**: Identifies the tracking area in LTE networks.
5. **ECGI (EUTRAN CGI)**: A unique identifier for cells in LTE networks.
6. **LAI (Local Area Identifier)**: Identifies the local area within a GSM network.
7. **Macro eNodeB Field**: Information related to the macro eNodeB, a type of base station in LTE networks.
8. **Extended Macro eNodeB Field**: Additional information for extended macro eNodeB configurations.
9. **Cell Changed**: Indicates whether the user's device has changed cells within the network.

## Tunnel Information

1. **IPv4 Address Uplink** **(SGW)**: The IPv4 address for the uplink from the Serving Gateway (SGW).
2. **IPv4 Address Downlink (eNodeB)**: The IPv4 address for the downlink to the eNodeB (Evolved Node B).
3. **IPv6 Address Uplink (SGW)**: The IPv6 address for the uplink from the Serving Gateway (SGW).
4. **IPv6 Address Downlink (eNodeB)**: The IPv6 address for the downlink to the eNodeB (Evolved Node B).
5. **TEID Uplink (SGW)**: The Tunnel Endpoint Identifier for the uplink from the Serving Gateway (SGW).
6. **TEID Downlink (eNodeB)**: The Tunnel Endpoint Identifier for the downlink to the eNodeB (Evolved Node B).
7. **CONTROL TEID**: The Tunnel Endpoint Identifier used for control plane signaling.
8. **CONTROL IP**: The IP address used for control plane signaling.
9. **Radio Access Type (RAT)**: The type of radio access technology being used (e.g., LTE, 5G).

## Key Performance Indicator(KPIs)

1. **Cplane Latency**: The latency in the control plane, measuring the delay in signaling and control messages.
2. **Per IMSI Metrics**:
   * **Uplane Bandwidth/Throughput**: The bandwidth or throughput in the user plane, specific to each IMSI .
   * ﻿﻿**Uplane Latency**: The latency in the user plane, measuring the delay in data transmission for each IMSI.
