Abstract

The invention relates to apparatuses, methods, systems, computer programs, computer program products and computer-readable media.

Claims

1. An apparatus comprising:

at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to;

receive a network identity of a virtual operational network, the virtual operational network having a plurality of donor system candidates, said virtual operational network being a separated operational network entity and/or service area commonly agreed and supported by one or multiple available donor systems, and said network identity being unique throughout the involved donor systems for the entire operation or active time of the virtual operational network;

receive a configuration profile, the configuration profile comprising parameters in relation to resource usage in the virtual operational network;

select at least one donor node from the donor system candidates; and

indicate the network identity and the configuration profile to the selected at least one donor node in connection with setting up a backhaul connection to the selected at least one donor node; and

monitor and keep other relay nodes of a group of cooperative relay nodes and/or donor systems updated of available capacity and/or load status on an access link and/or backhaul link,

wherein the apparatus comprises a relay node belonging to the group of cooperative relay nodes, wherein the group of cooperative relay nodes is within the virtual operational network, and wherein the virtual operational network is a multi-operator network.

2. The apparatus of claim 1, wherein the configuration profile comprises at least one of the following parameters:

spectrum allocation of at least a primary carrier, global cell identification, layer 1 cell identification, and cell-selection control parameters.

3. A computer program product embodied on a non-transitory computer readable medium, the computer program being configured to control a processor to perform:

receiving a network identity of a virtual operational network, the virtual operational network having a plurality of donor system candidates, said virtual operational network being a separated operational network entity and/or service area commonly agreed and supported by one or multiple available donor systems, and said network identity being unique throughout the involved donor systems for the entire operation or active time of the virtual operational network;

receiving a configuration profile, the configuration profile comprising parameters in relation to resource usage in the virtual operational network;

selecting at least one donor node from the donor system candidates;

indicating the network identity and the configuration profile to the selected at least one donor node in connection with setting up a backhaul connection to the selected at least one donor node; and

monitoring and keeping other relay nodes of a group of cooperative relay nodes and/or donor systems updated of available capacity and/or load status on an access link and/or backhaul link,

wherein the processor is in a relay node belonging to the group of cooperative relay nodes, wherein the group of cooperative relay nodes is within the virtual operational network, and wherein the virtual operational network is a multi-operator network.

4. A method comprising:

receiving a network identity of a virtual operational network, the virtual operational network having a plurality of donor system candidates, said virtual operational network being a separated operational network entity and/or service area commonly agreed and supported by one or multiple available donor systems, and said network identity being unique throughout the involved donor systems for the entire operation or active time of the virtual operational network;

receiving a configuration profile, the configuration profile comprising parameters in relation to resource usage in the virtual operational network;

selecting at least one donor node from the donor system candidates;

indicating the network identity and the configuration profile to the selected at least one donor node in connection with setting up a backhaul connection to the selected at least one donor node; and

monitoring and carrying out updating of available capacity and/or load status on an access link and/or backhaul link,

wherein the virtual operational network is a multi-operator network comprising a group of cooperative relay nodes.

5. The method of claim 4, wherein the configuration profile comprises at least one of the following parameters:

spectrum allocation of at least a primary carrier, global cell identification, layer 1 cell identification, and cell-selection control parameters.
