Mobile Number Portability

MNP in Germany

In Germany, the regulatory body Bundesnetzagentur (Federal Network Agency) is represented by an independent Clearing house for Communications Services (ICCS) and is crucial in managing the porting process between the donor and recipient service providers.

MNP process is triggered by the Recipient Service Provider when the Port-IN request is created and submitted to ICCS, which creates as result the Port-Out request to the Donor Service Provider (from which the phone number will be migrated). ICCS handles the communication between the Port-IN and Port-Out requests.

From the Customer perspective:

  • The MNP process in Germany can take a minimum of 6 business days from the day the Port-IN is requested to a maximum of 123 business days.
  • Port-Out request is possible up to 3 months after termination of the contract with the Partner.

MNP Lifecycles

MNP-OUT

At a higher level, the MNP-OUT (Port-OUT) request begins on the donor’s side in pending status, and at this point, the carrier can prevent the request from moving to pending status in the case of due payments. Following this state, typical validations occur from 1GLOBAL and communications between the current carrier, the new carrier, and ICCS. This process results in either the request to progress to a scheduled state or be rejected. Once scheduled, the customer can cancel the request and remain with their current provider. If no cancellation is made, the portability process is initiated, and 1GLOBAL facilitates communication with relevant entities like the ICCS.

MNP-IN

The MNP-IN (Port-In) process is initiated when the customer requests to port their number to the new provider after informing the donor. The new provider creates a draft MNP in order, which is validated against the donor’s request and then transitions to a pending state. The ICCS processes the request, and the donor provider can accept and send it to scheduled status or reject it and send rejected status as described in MNP OUT flow. If accepted, the order moves to a scheduled status, where the customer can cancel on the new carrier’s side for a specified period. Once the porting request is locked, the porting process can't be changed anymore. When the scheduled date is met, it goes to processing status, which consists of the de-provisioning of the phone number in the donor’s carrier side and the provisioning on the new provider, who provides the service, in this case, 1GLOBAL and its Partner. Finally, the request is marked as status-completed, and the customer is notified. 1GLOBAL will facilitate the process of moving the phone number to the customer’s new profile.

API endpoints

Endpoints were added as Mandatory and Optional. The reasoning for this clustering is explained as follows:

  • Mandatory means they are part of the MNP core process and without them, it is not possible to go through the process from the start until the end.
  • Optional means they are available to be considered by the Partner to enable specific business, customer service processes supporting the MNP process.

Warning on System Logic & Automated Retries

No DE rejection enum in the verified source set is marked for automatic retry.

Do not build manual retry loops that blindly replay rejected submissions. For DE, the safe integration pattern is:

  • inspect the rejection enum and any message
  • correct the underlying data, donor selection, opt-in state, or schedule
  • create a new request only after the issue has been fixed

For cancellation_too_late, there is no retry path. The cancellation attempt is declined and the request remains in scheduled.
