Overview

This node, named "Summa," is designed to interact with the Summa API (version indicated dynamically). It supports multiple resources and operations related to telecommunications data management. Specifically, for the resource Send Protocol and operation Send Cancel Location MME, the node sends a cancel location request to the MME (Mobility Management Entity) using the provided IMSI (International Mobile Subscriber Identity).

This functionality is useful in telecom environments where you need to manage subscriber sessions or locations dynamically, such as cancelling a subscriber's current location registration in the network. Practical examples include:

  • Forcing a subscriber to re-register on the network after a session drop.
  • Managing subscriber mobility and session control in LTE networks.

Properties

Name Meaning
Imsi The International Mobile Subscriber Identity (IMSI) of the subscriber for whom the cancel location request will be sent. This is a required string input.

Output

The node outputs JSON data representing the response from the Summa API after sending the cancel location request. The exact structure depends on the API response but typically includes status information about the cancel location operation.

If the node supports binary data output, it would represent any raw protocol or message payloads returned by the API, but this is not explicitly indicated in the provided code snippet.

Dependencies

  • Requires an API key credential for authenticating with the Summa API.
  • Uses an HTTP client internally to communicate with the Summa backend service.
  • Depends on the Summa API being accessible and properly configured.
  • The node uses internal helper classes for state management and operation resolution, which are part of the bundled dependencies.

Troubleshooting

  • Authentication errors: Ensure that the API key credential is correctly set up and valid.
  • Invalid IMSI format: The IMSI must be a valid string representing a subscriber identity; invalid values may cause API errors.
  • Network issues: Connectivity problems to the Summa API endpoint can cause request failures.
  • API errors: If the Summa API returns an error, check the response message for details; common issues include invalid parameters or unsupported operations.
