Overload control mechanism

An apparatus comprising

• at least one processor;
• and
• at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
• determining, in response to detecting that a command to release resources a first amount is received or that one or more of flows do not reach quality of service level of the flow, a second amount corresponding to resources missing to satisfy quality of service requirements of active flows;
• sorting, in response to having two or more flows, the flows to an order according to a predetermine sorting rule for flows;
• releasing resources flow by flow according to the order until enough resources have been released.

A method comprising:

• monitoring how two or more network slices use resources;
• determining, in response to the use not being within slice constraints, per a network slice, an amount of resources to be released by the network slice;
• and
• causing commanding network slices to release resources correspondingly.

A non-transitory computer readable medium comprising program instructions for causing an apparatus to perform at least one of a first process and a second process:

• wherein the first process comprises the following:
• monitoring how two or more network slices use resources;
• determining, in response to the use not being within slice constraints, per a network slice, an amount of resources to be released by the network slice;
• and
• causing commanding network slices to release resources correspondingly,
• wherein the second process comprises the following:
• determining, in response to detecting that a command to release resources a first amount is received or that one or more of flows do not reach quality of service level of the flow, a second amount corresponding to resources missing to satisfy quality of service requirements of active flows;
• sorting, in response to having two or more flows, the flows to an order according to a predetermine sorting rule for flows;
• releasing resources flow by flow according to the order until enough resources are released.
