Technique for controlling and handling probe tunnel set up

摘要

A technique for controlling and handling set up of a probe tunnel stretching from an access network node through a core network towards a core network node is described. In a method implementation, probe tunnel set up control comprises determining a First Fully Qualified Tunnel Endpoint Identifier (F-TEID) associated with the core network node and sending a probe tunnel set up instruction to the access network node. The instruction commands the access network node to locally set up the probe tunnel towards the core network node based on the F-TEID.

1. A method of controlling set up of a probe tunnel used for probing purposes stretching from an access network node through a core network towards a core network node, the method comprising:
determining a first Fully Qualified Tunnel Endpoint Identifier, F-TEID, associated with the core network node; sending a first probe tunnel set up instruction to the access network node for instructing the access network node to locally set up the probe tunnel towards the core network node based on the first F-TEID; and sending a second probe tunnel set up instruction to the core network node for instructing the core network node to locally set up the probe tunnel based on a second F-TEID associated with the access network node; wherein at least one of the first F-TEID and the second F-TEID is determined from a predetermined pool of F-TEIDs pre-allocated to network nodes participating in the probe tunnel setup.
