Abstract

An apparatus is provided which includes a first connection unit configured to provide connection to a user equipment, and a processor configured to detect whether a handover of the user equipment is required, and, if a handover is required, to establish mobility information regarding the mobility state of the apparatus as mobility information of the user equipment, and to send the mobility information to at least one network element involved in the handover of the user equipment.

Claims

1. An apparatus comprising

a first connection unit configured to provide connection to a user equipment, and

a processor configured to:

detect whether a handover of the user equipment is required, and, if a handover is required,

establish mobility information regarding the mobility state of the apparatus as mobility information of the user equipment, and

send the mobility information to at least one network element involved in the handover of the user equipment.

2. The apparatus according to claim 1, wherein:

the at least one network element involved in the handover comprises a network control element of a target cell of the handover.

3. The apparatus according to claim 2, wherein:

the processor is configured to send the mobility information in a handover request message.

4. The apparatus according to claim 2, wherein:

the processor is configured to detect whether the apparatus and target cell are movin relative to each other, and to send the mobility information only in case the apparatus and target cell are moving relative to each other.

5. The apparatus according to claim 1, wherein:

the at least one network element involved in the handover comprises the user equipment.

6. The apparatus according to claim 5, wherein the user equipment stores the received mobility information in a variable and/or updates its mobility state according to the received mobility information.

7. The apparatus according to claim 5, wherein:

the processor is configured to send the mobility information also to a network control element of a target cell of the handover.

8. The apparatus according to claim 1, wherein:

the processor is configured to send the mobility information during handover by adjusting the mobility parameters of the user equipment.

9. The apparatus according to claim 1, further comprising:

a second connection unit configured to provide connection to a first network control node, wherein

the processor is configured to relay communication from the at least one network control node via the second connection unit to the user equipment via the first connection unit and vice versa.

10. An apparatus comprising:

a connection unit, and

a processor configured to;

receive, via the connection unit, mobility information regarding a mobility state of a user equipment, which is to perform a handover from a network control element to the apparatus, and

use the received mobility information for preparing the handover of the user equipment.

11. The apparatus according to claim 10, wherein:

the processor is configured to adapt the mobility parameters of the user equipment after receiving the mobility state of the user equipment.

12. An apparatus comprising:

a connection unit, and

a processor configured to;

receive, via the connection unit, mobility information regarding a mobility state from a first network control element, and

replace a mobility state of the apparatus by the mobility state received in the mobility information upon preparing a handover from the first network control element to a second network control element.

13. The apparatus according to claim 12, wherein the first network control element and the second network control element are moving relative to each other.

14. A method comprising:

providing a connection to a user equipment,

detecting whether a handover of the user equipment is required,

and, if a handover is required,

establishing mobility information regarding the mobility state of an apparatus carrying out the method as mobility information of the user equipment, and

sending the mobility information to at least one network element involved in the handover of the user equipment.

15. The method according to claim 14, wherein:

the at least one network element involved in the handover comprises a network control element of a target cell of the handover.

16. The method according to claim 15, further comprising:

sending the mobility information in a handover request message.

17. The method according to claim 15, further comprising:

detecting whether the apparatus carrying out the method and a target cell are moving relative to each other, and

sending the mobility information only in case the apparatus and the target cell are moving relative to each other.

18. The method according to claim 14, wherein:

the at least one network element involved in the handover comprises the user equipment.

19. The method according to claim 18, further comprising performing at least one of the following:

storing the received mobility information in a variable at the user equipment, and

updating the mobility state of the user equipment based on the received mobility information.

20. The method according to claim 18, further comprising:

sending the mobility information also to a network control element of a target cell of the handover.

21. The method according to claim 14, further comprising:

sending the mobility information during handover by adjusting the mobility parameters of the user equipment.

22. The method according to claim 14, further comprising:

providing connection to a first network control node, and

relaying communication from the at least one network control node to the user equipment and vice versa.

23. A method comprising:

receiving mobility information regarding a mobility state of a user equipment, which is to perform a handover from a network control element to an apparatus carrying out the method, and

using the received mobility information for preparing the handover of the user equipment.

24. The method according to claim 23, further comprising:

adapting the mobility parameters of the user equipment after receiving the mobility state of the user equipment.

25. A method comprising:

receiving mobility information regarding a mobility state from a first network control element, and

replacing a mobility state of the apparatus carrying out the method by the mobility state received in the mobility information upon preparing a handover from the first network control element to a second network control element.

26. The method according to claim 25, wherein the first network control element and the second network control element are moving relative to each other.
