US 10,897,785 B2 · Method and system for general packet radio service tunneling protocol (GTP) probing

Abstract

Methods and systems for probing General Packet Radio System (GPRS) Tunneling Protocol (GTP) links in a communication network are disclosed. According to principles described herein, originator and responder nodes (endpoints) are configured to use a probing interval that can be changed dynamically to adapt the probing frequency to the prevailing conditions measured and/or capabilities available at the originator and/or the responder. According to a broad aspect, a method for a network node includes receiving a probing request message originating from a first peer node via a GTP link, the probing request message containing a request indication for a probing interval recommendation for probing the GTP link, in response to the probing request message received, determining a probing interval recommendation for probing the GTP link and sending a probing response message to the first peer node via the GTP link, the probing response message containing the probing interval recommendation determined.

Dependent claims

A method for a network node for probing General Packet Radio System (GPRS) Tunneling Protocol (GTP) links operable to carry data traffic between the network node and peer nodes in a communication network, the method comprising at the network node:

receiving a probing request message originating from a first peer node via a GTP link, the probing request message containing a request indication for a probing interval recommendation for probing the GTP link;
in response to the probing request message received, determining a probing interval recommendation for probing the GTP link, wherein the probing interval recommendation comprises one of a probing interval value and a probing method value indicative of a probing interval value;
and
sending a probing response message to the first peer node via the GTP link, the probing response message containing the probing interval recommendation.
