Abstract
A method, a system and network nodes use an indication of possible duplicates of units, so that these units can be handled differently than other units. The unit is indicated to be a possible duplicate to the entity to which it is resent because no response was received from the entity it was sent to.

A method comprising:
- sending a unit to a first receiving entity in a telecommunications system;
- in the event that no response is received from the first receiving entity, resending the unit to a second receiving entity with an indication of a possible duplicate, the indication of a possible duplicate indicating that the unit was resent because no response was received;
- and
- sending a message to the second receiving entity to release or delete the unit depending on a subsequently determined status of the first receiving entity.
