Abstract

A method for providing device connectivity to a radio access network, wherein at least two devices are connectable or connected to the radio access network and wherein the at least two devices are members of a group of devices within a wireless local network, the members of the group of devices having the capability to establish a direct connection with other members of the group of devices, includes providing connection information used for a connection between a first device of the at least two devices and the radio access network to a second device of the at least two devices. The connection information enables the second device to connect to the radio access network.

First claim

The invention claimed is:

1. A method for establishing connectivity between each of at least two devices and a radio access network, wherein the at least two devices are members of a group of devices within a wireless local network capable of establishing direct connections with one another, the method comprising:
establishing a connection directly between a first device of the at least two devices and the radio access network, wherein the connection directly between the first device and the radio access network utilizes connection information provided by the radio access network to the first device; and
establishing a connection directly between a second device of the at least two devices and the radio access network using the connection information provided by the radio access network to the first device.

2. The method according to claim 1 , wherein the connection information provided by the radio access network to the first device comprises at least one of a connection parameter, a bearer parameter, or a radio bearer parameter.

3. The method according to claim 1 , wherein establishing the connection directly between the second device and the radio access network is performed based on at least one of finishing a data transmission between the first device and the radio access network or a data transmission pause of a predetermined length.

4. The method according to claim 1 , wherein the connection information provided by the radio access network to the first device is at least one of moved or transmitted from the first device to the second device or is activated within the second device.

5. The method according to claim 1 , further comprising storing the connection information provided by the radio access network to the first device within a virtual device.

6. The method according to claim 5 , wherein the virtual device runs on at least one of hardware of the first device or hardware of the second device.

7. The method according to claim 5 , wherein the virtual device is a functionality which can be at least one of moved between or activated within the members of the group of devices within the wireless local network.

8. The method according to claim 5 , wherein the virtual device is linked to a specific radio bearer provided by the radio access network to the first device or to a bearer provided by the radio access network to the first device that can be shared by different devices.

9. The method according to claim 1 , wherein only one of the first device and the second device can be or is active at one point in time.

10. The method according to claim 1 , wherein one or more of the members of the group of devices within the wireless local network are at least one of not connectable or not connected directly to the radio access network.

11. The method according to claim 10 , wherein one of the first device or the second device is directly connected to the radio access network and has the functionality of a Master Device or Master Machine or Master Gateway for assisting the one or more members of the group of devices within the wireless local network which are not connectable or connected directly to the radio access network to gain access or a connection to the radio access network.

12. The method according to claim 1 , further comprising:
broadcasting or announcing, by at least one of the first device or the second device, a group ID to other members of the group of devices via the wireless local network.

13. The method according to claim 1 , wherein the group of devices is formed on the basis of one or more of geographical information, a service requirement, or a potential load limit.

14. The method according to claim 1 , wherein at least one of the members of the group of devices is a Machine Type Communication (MTC) device.

15. The method according to claim 1 , wherein the wireless local network is at least one of an ad-hoc network, a WLAN network, or a Bluetooth network.

16. The method according to claim 1 , wherein the radio access network is an LTE network.

17. The method according to claim 1 , wherein the at least two devices are connectable to the radio access network via an access point.

18. The method according to claim 17 , wherein the access point is an eNodeB (eNB).

19. The method according to claim 17 , wherein a prior connection of the first device between the access point and at least one further functional element of the radio access network is maintained.

20. The method according to claim 19 , wherein the at least one further functional element of the radio access network is a Serving Gateway (SGW).

21. A network structure for establishing connectivity between each of at least two devices and a radio access network, wherein the at least two devices are members of a group of devices within a wireless local network capable of establishing direct connections with one another, the network structure comprising:
a first device configured to establish a connection directly with a radio access network wherein the connection directly between the first device and the radio access network utilizes connection information provided by the radio access network to the first device; and
a second device configured to establish a connection directly with the radio access network using the connection information provided by the radio access network to the first device.
