## Abstract

A method for managing notification requests in a communication network is disclosed. The method comprises receiving notification requests from a system of the communication network (110) and, for received notification requests, obtaining an intended outcome of the requested notification (120) and assigning a priority to the received notification request (130). The method further comprises selecting for processing at least one received notification request, wherein the at least one notification request is selected on the basis of a priority assigned to the notification request (160). Assigning a priority to the received notification request comprises estimating a probability that the intended outcome of the requested notification will be achieved, and setting the priority of the received notification request according to the estimated probability (140). Estimating a probability that the intended outcome of the requested notification will be achieved comprises submitting parameters of the received notification request to a model, the model having been trained using parameters of historical requested notifications and their outcomes (150).

adding the new notification request to a position in the queue based on the priority assigned to the new notification request.

### Claim 5 (depends on 4)

The method of claim 4, wherein
the step of adding the new notification request to a position in the queue based on the priority assigned to the new notification request is performed as a result of a determination that the first performance parameter of the first delivery channel satisfies the first condition.

### Claim 6 (depends on 1)

The method of claim 1, further comprising:
sending the notification of the selected notification request; and
obtaining information about whether the intended outcome of the notification was achieved.

### Claim 7 (depends on 6)

The method of claim 6, further comprising:
assembling parameters of the sent notification and the obtained information about whether the intended outcome was achieved into a training data set for the model.

### Claim 8 (depends on 7)

The method of claim 7, wherein assembling parameters of the sent notification and the obtained information about whether the intended outcome was achieved into a training data set for the model comprises:
assembling the parameters of the sent notification into an input features vector; and
labelling the input features vector as true if the obtained information indicates that the intended outcome was achieved and as false otherwise.

### Claim 9 (depends on 7)

The method of claim 7, further comprising:
checking for a training trigger event; and
on detection of the training trigger event, updating the model using the assembled training data set.

### Claim 10 (depends on 9)

The method of claim 9, further comprising:
comparing the assigned priority of a received notification request to an importance threshold; and
