7. The apparatus according to claim 1 , wherein the condition for a handover is at least one condition selected from the group of conditions consisting of a signal to noise ratio, a service load, an interference, a strategy of the operator of the network, a preferred policy, a roaming agreement, a capability, in particular a capability of a target base station, a trigger event and a reject information.

8. A method for a handover in a network, the method comprising:

detecting a condition for a handover;

selecting a first group, wherein the first group comprises at least one first target apparatus member;

receiving a second group selected by a mobile station, wherein the second group comprises at least one second target apparatus member;

wherein the selection of the first group is performed timely before performing the selection of the second group;

determining a difference group of the first target apparatus members and the second target apparatus members;

selecting at least one target apparatus member of the difference group;

sending a preparation information to the at least one selected target apparatus member of the difference group; and

sending a handover confirmation message to the at least one selected target apparatus member of the difference group, which handover confirmation message comprises at least one information selected from the group consisting of a confirmation information, an urgent confirm information, an action time information, a time stamp information, a fast ranging mode information, an address information and a MAC address information.

9. The method according to claim 8 , wherein the method is performed in a handover preparation phase of a handover procedure.

10. The method according to claim 8 , wherein the method is performed in a handover action phase of a handover procedure.

11. A computer program product comprising a non-transitory computer-readable storage medium bearing computer program code embodied therein for use with a computer, the computer program code comprising code for performing a method comprising:

detecting a condition for a handover;

selecting a first group, wherein the first group comprises at least one first target apparatus member;

receiving a second group selected by a mobile station, wherein the second group comprises at least one second target apparatus member;

wherein the selection of the first group is performed timely before performing the selection of the second group;

determining a difference group of the first target apparatus members and the second target apparatus members;

selecting at least one target apparatus member of the difference group;

sending a preparation information to the at least one selected target apparatus member of the difference group; and

sending a handover confirmation message to the at least one selected target apparatus member of the difference group, which handover confirmation message comprises at least one information selected from the group consisting of a confirmation information, an urgent confirm information, an action time information, a time stamp information, a fast ranging mode information, an address information and a MAC address information.

12. The computer program product according to claim 11 , wherein the method is performed in a handover preparation phase of a handover procedure.

13. The computer program product according to claim 11 , wherein the method is performed in a handover action phase of a handover procedure.

14. The computer program product according to claim 11 , wherein the at least one selected target apparatus member of the difference group originates from the second group.

15. The computer program product according to claim 11 , wherein the preparation information is sent to all selected target apparatus members of the difference group.

16. The computer program product according to claim 11 , wherein the preparation information is sent to all target apparatus members of the difference group originating from the second group.

17. The computer program product according to claim 11 , wherein the method further comprises:

send an acknowledge message, which acknowledge message comprises at least one information from the group consisting of a confirmation information, an urgent confirm information, an action time information, a time stamp information, a fast ranging mode information, an address information and a MAC address information.

18. The computer program product according to claim 11 , wherein the condition for a handover is at least one condition selected from the group of conditions consisting of a signal to noise ratio, a service load, an interference, a strategy of the operator of the network, a preferred policy, a roaming agreement, a capability, in particular a capability of a target base station, a trigger event and a reject information.
