Abstract

In one embodiment, the method includes obtaining virtual relay context information enabling by one or more relay mobile device candidates to relay traffic; and applying the virtual relay context information to be configured as a respective relay mobile device of the one or more relay mobile device candidates for relaying traffic.

Claims (35)

1 . An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform:

obtaining virtual relay context information enabling the apparatus to serve at least one remote mobile device as a relay mobile device to relay traffic between the at least one remote mobile device and a base station of a mobile communication network, wherein the virtual relay context information further comprises the following:

an identifier corresponding to the virtual relay context information;

scheduling configuration;

configured grant configuration;

one or more bearer configurations;

channel configuration;

Non Access Stratum (NAS) layer configuration;

Radio Resource Control (RRC) layer configuration;

Medium Access Control (MAC) layer configuration; and

Physical (PHY) layer configuration; and

based on a condition specified by the virtual relay context information being locally determined by the apparatus to be fulfilled and when an activation indication is received from the at least one remote mobile device, applying the virtual relay context information to be configured as the relay mobile device for the at least one remote mobile device,

wherein the virtual relay context information is obtained prior to the condition being fulfilled and the activation indication being received, and wherein the virtual relay context information is applied without requiring further configuration signaling from the mobile communication network.

2 . The apparatus according to claim 1 , the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus further to perform:

determining whether or not the condition of a plurality of conditions is fulfilled, wherein the plurality of conditions enable the apparatus to serve as a relay mobile device between the at least one remote mobile device and the base station.

3 . The apparatus according to claim 2 , wherein the virtual relay context information is obtained by the apparatus and at least one other apparatus to serve the at least one remote mobile device as a respective relay mobile device to relay traffic between the at least one remote mobile device and a base station of a mobile communication network.

4 . The apparatus according to claim 3 , the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus further to perform:

obtaining the activation indication indicating to apply the virtual relay context information from the at least one remote mobile device, wherein the virtual relay context information is applied based, at least in part, on the obtained activation indication of the at least one remote mobile device.

5 . The apparatus according to claim 4 wherein the virtual relay context information comprises at least part of the one or more conditions for the one or more relay mobile device candidates.

6 . The apparatus according to claim 1 , the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus further to perform:

providing a condition change indication indicative of a change of the at least one condition disabling/enabling the apparatus to apply the virtual relay context information and serve as a relay mobile device between the at least one remote mobile device and the base station.

7 . The apparatus according to claim 1 , wherein the virtual relay context information is obtained from the at least one remote mobile device and/or the mobile communication network.

8 . A method comprising:

obtaining, by an apparatus, virtual relay context information enabling to serve at least one remote mobile device as a relay mobile device to relay traffic between the at least one remote mobile device and a base station of a mobile communication network, wherein the virtual relay context information further comprises the following:

an identifier corresponding to the virtual relay context information;

scheduling configuration;

configured grant configuration;

one or more bearer configurations;

channel configuration;

Non Access Stratum (NAS) layer configuration;

Radio Resource Control (RRC) layer configuration;

Medium Access Control (MAC) layer configuration; and

Physical (PHY) layer configuration; and

based on a condition specified by the virtual relay context information being locally determined by the apparatus to be fulfilled and when an activation indication is received from the at least one remote mobile device, applying, by the apparatus, the virtual relay context information to be configured as the relay mobile device for the at least one remote mobile device,

wherein the virtual relay context information is obtained prior to the condition being fulfilled and the activation indication being received, and wherein the virtual relay context information is applied without requiring further configuration signaling from the mobile communication network.
