Method for controlling a handover between two network access devices

1 - 9 . (canceled)

10 . A method for controlling a handover between two network devices, comprising:

determining at least one quality parameter in a link layer based on signal transmissions on a physical layer, with a mobility-controlling mechanism of a network layer; and

carrying out the handover as a function of the at least one quality parameter, including, as a function of the at least one quality parameter, either

relaying, in preparation for the handover, at least one message received by a currently supplying network access device from the physical layer to the network layer, or

suppressing transmission of the at least one message.

11 . A method in accordance with claim 10 , further comprising making a decision regarding said relaying in an intermediate layer arranged between the link layer and the mobility-controlling network layer.

12 . A method in accordance with claim 11 , wherein said making of the decision is in accordance with a comparison of the at least one quality parameter with at least one specified threshold value.

13 . A method in accordance with claim 12 , wherein the at least one threshold value is defined specific to a network access device.

14 . A method in accordance with claim 13 , wherein the handover is carried out between two network devices supporting two different standards on the physical layer.

15 . A method in accordance with claim 14 , further comprising not carrying out the handover until a specified time interval has elapsed after completion of a preceding handover.

16 . A method in accordance with claim 15 , further comprising not carrying out the handover until after a determined number of received advertisements has been exceeded.

17 . A method for handover between two network devices, comprising:

carrying out the handover as a function of at least one quality parameter determined in a link layer based on signal transmissions on a physical layer, with a mobility-controlling mechanism of a network layer being used to decide on the handover; and

inserting, in preparation for the handover, an advertisement in reception signals relayed to the network layer according to the at least one quality parameter.

18 . A method in accordance with claim 17 , further comprising making a decision regarding said insertion of the at least one advertisement in an intermediate layer arranged between the link layer and the mobility-controlling network layer.

19 . A method in accordance with claim 18 , wherein said making of the decision is in accordance with a comparison of the at least one quality parameter with at least one specified threshold value.

20 . A method in accordance with claim 19 , wherein the at least one threshold value is defined specific to a network access device.

21 . A method in accordance with claim 20 , wherein the handover is carried out between two network devices supporting two different standards on the physical layer.

22 . A method in accordance with claim 21 , further comprising not carrying out the handover until a specified time interval has elapsed after completion of a preceding handover.

23 . A method in accordance with claim 22 , further comprising not carrying out the handover until after a determined number of received advertisements has been exceeded.

24 . A subscriber terminal communicating with first and second network access devices, comprising:

means for receiving signals of a connection transmitted on a physical layer from the first network access device;

means for determining at least one quality parameter based on received signals; and

means for controlling relaying of an advertisement, received from the first network access device, to a mobility-controlling mechanism of a network layer, according to the at least one quality parameter, with the mobility-controlling mechanism being designed to control a handover of a link to the second network access device according to received advertisements.
