Relay extension in cellular network

Abstract

This document discloses a solution for performing rerouting of a relayed connection. In an aspect, a method for an anchor terminal device supporting relaying between an access node and an end terminal device comprises: receiving a message requesting rerouting of said relaying, the message comprising at least one information element indicating at least one candidate terminal device; determining a communication delay between the anchor terminal device and the end terminal device via at least one of said at least one candidate terminal device and comparing the determined communication delay with a maximum delay threshold; if at least one determined communication delay is smaller than the maximum delay threshold, rerouting the relaying between the anchor terminal device and the end terminal device via one of the at least one candidate terminal device that provides the communication delay smaller than the maximum delay threshold, wherein the rerouting is carried out autonomously without receiving from the access node a reconfiguration message instructing the rerouting configuration; and if no communication delay is smaller than the maximum delay threshold, causing transmission of a message to the access node, the message indicating a need for reconfiguration of the relaying.
