Abstract

A system for sending a relay notification comprises a transceiver and a processor. The processor is configured to use the transceiver to receive a request for allowing a mobile device to be used by a further mobile device as a relay to a mobile communication network. The processor is further configured to determine whether the mobile device is to act as a relay for the further mobile device based on the unique identifier of the further mobile device, and to use the transceiver to notify the mobile device that it is to act as a relay for the further mobile device in dependence on the determination. The mobile device is configured to receive the notification from the system. The processor is further configured to start relaying data received from the further mobile device to the mobile communication network upon receiving the notification.

First claim

The invention claimed is:

1. A system for sending a relay notification, the system comprising:
a receiver;
a transmitter; and
at least one processor configured to use said receiver to receive a request for allowing a mobile device that has attached to a mobile communication network to be used as a relay to the mobile communication network by a further mobile device that is also attached to the mobile communication network, to determine a unique identifier of said further mobile device based on said request, to determine a unique identifier of said mobile device based on said request; to determine a relation between said mobile device and said further mobile device based on said unique identifier of said mobile device and said unique identifier of said further mobile device, and to determine whether said mobile device is to act as a relay for said further mobile device based on said relation, and to use said transmitter to notify said mobile device to act as a relay for said further mobile device in dependence on said determination.

2. The system of claim 1 , wherein said unique identifier comprises a permanent identifier of said mobile device identifying said mobile device in said mobile communication network and/or a temporary identifier of said mobile device identifying said mobile device in said mobile communication network.

3. The system of claim 2 , wherein said unique identifier comprises an International Mobile Subscriber Identity, a Globally Unique Temporary User Equipment (UE) Identity, a Proximity Services identifier, and/or a Cell Radio Network Temporary Identifier (C-RNTI).

4. The system of claim 1 , wherein said at least one processor is further configured:
to obtain information relating to said further mobile device based on said unique identifier of said further mobile device; and
to determine whether said mobile device is to act as a relay for said further mobile device based on said information relating to said further mobile device.

5. The system of claim 4 , wherein said at least one processor is further configured to obtain said information from a database in said mobile communication network and/or from a trusted third party server.

6. The system of claim 1 , wherein said at least one processor is further configured:
to obtain information relating to said further mobile device based on said unique identifier of said further mobile device;
to determine a unique identifier of said mobile device based on said request;
to obtain information relating to said mobile device based on said unique identifier of said mobile device;
to determine a relation between said mobile device and said further mobile device based on said information relating to said mobile device and on said information relating to said further mobile device; and
to determine whether said mobile device is to act as a relay for said further mobile device based on said relation.

7. The system of claim 1 , wherein said at least one processor is further configured:
to determine whether data use can be charged to said further mobile device based on said unique identifier of said further mobile device and
to determine whether said mobile device is to act as a relay for said further mobile device in dependence on whether data use can be charged to said further mobile device.

8. The system of claim 1 , wherein said at least one processor is further configured to implement a Third Generation Partnership Project (3GPP) Proximity Services Function.

9. A mobile device that is attached to a mobile communication network, the mobile device comprising:
a receiver;
a transmitter; and
at least one processor configured to use said receiver to receive a notification from a system, said notification notifying said mobile device to act as a relay to said mobile communication network comprising said system for a further mobile device that is also attached to said mobile communication network, and to use said receiver and said transmitter to start relaying data received from said further mobile device to said mobile communication network upon receiving said notification.

10. The mobile device of claim 9 , wherein said at least one processor is further configured to receive said identifier notification from a system that comprises:
a receiver;
a transmitter; and
at least one processor configured to use said receiver to receive a request for allowing said mobile device to be used by a further mobile device as a relay to a mobile communication network, to determine a unique identifier of said further mobile device based on said request, to determine a unique identifier of said mobile device based on said request; to determine a relation between said mobile device and said further mobile device based on said unique identifier of said mobile device and said unique identifier of said further mobile device, and to determine whether said mobile device is to act as a relay for said further mobile device based on said relation, and to use said transmitter to notify said mobile device to act as a relay for said further mobile device in dependence on said determination.

11. A method of sending a relay notification, the method comprising:
receiving a request for allowing a mobile device that has attached to a mobile communication network to be used as a relay to the mobile communication network by a further mobile device that is also attached to the mobile communication network;
determining a unique identifier of said further mobile device based on said request;
determining a unique identifier of said mobile device based on said request;
determining a relation between said mobile device and said further mobile device based on said unique identifier of said mobile device and said unique identifier of said further mobile device;
determining whether said mobile device is to act as a relay for said further mobile device based on said relation; and
notifying said mobile device to act as a relay for said further mobile device in dependence on said determination.

12. A method of receiving a relay notification, the method comprising:
receiving a notification from a system in a mobile communication network on a mobile device that has attached to said mobile communication network, said notification notifying said mobile device to act as a relay to said mobile communication network for a further mobile device that has also attached to said mobile communication network; and
starting relaying data received from said further mobile device to said mobile communication network upon receiving said notification.

13. A non-transitory computer medium having stored thereon one or more computer programs comprising at least one software code portion that, when run on a computer system, causes the computer system to carry out operations including:
receiving a request for allowing a mobile device that has attached to a mobile communication network to be used as a relay to the mobile communication network by a further mobile device that is also attached to the mobile communication network;
determining a unique identifier of said further mobile device based on said request;
determining a unique identifier of said mobile device based on said request;
determining a relation between said mobile device and said further mobile device based on said unique identifier of said mobile device and said unique identifier of said further mobile device;
determining whether said mobile device is to act as a relay for said further mobile device based on said relation; and
notifying said mobile device to act as a relay for said further mobile device in dependence on said determination.
