Method for Control of a Connection Exchange Between Network Access Devices
A method in a user terminal controls f a connection exchange between network access devices in a connection layer, whereby at least one quality parameter is determined on the basis of signal transmissions of a current provider network access device on a physical layer. Depending on the at least one determined quality parameter, at least one request is transmitted to the first network access device and/or to at least one second network access device and, dependent on receipt of at least one message from the first and/or the at least one second network access device, a connection exchange to the second network access device is initiated.

10 . A method for controlling a connection transfer between first and second network-access devices that are assigned to an identical radio-communication system or to different radio-communication systems, comprising:
determining a quality parameter in a Link Layer based on signal transmissions in a presently provisioned connection between a user terminal and the first network-access device on a Physical Layer, the quality parameter being determined at the user terminal;
sending a request to the first network-access device and/or the second network-access device as a function of the quality parameter;
transmitting an advertisement message from the first and/or the second network-access device; and
initiating a connection transfer from the first network-access device to the second network-access device as a function of receiving the advertisement message .
11 . The method as claimed in claim 10 wherein
mobility-controlling mechanisms of a Network Layer are used for deciding whether to initiate the connection transfer,
advertisement messages from the presently provisioned first network-access device are selectively forwarded from the Physical Layer to the Network Layer, and
forwarding the advertisement messages from the presently provisioned first network-access device is carried out or suppressed as a function of the quality parameter.
12 . The method as claimed in claim 10 wherein
a decision about forwarding advertisement messages from the first and/or second network-access device is made in an intermediate layer located between the Link Layer and the mobility-controlling Network Layer.
13 . The method as claimed in claim 10 wherein
the user terminal receives from the second network-access device an advertisement message containing information about an address of the second network-access device, and
the user terminal enters the address information in a routing table.
14 . The method as claimed claim 13 wherein
after the user terminal sends the request, the user terminal sends a device-specific request to a designated network-access device, and
the user terminal uses the address information of the second network-access device for device-specific request.
15 . The method as claimed in claim 13 wherein
the user terminal uses the address information for setting up a connection to the second network-access device .
16 . The method as claimed in claim 10 wherein
the connection transfer takes place between network-access devices supporting different standards on the Physical Layer.
17 . The method as claimed in claim 11 wherein
a decision about forwarding advertisement messages from the first and/or second network-access device is made in an intermediate layer located between the Link Layer and the mobility-controlling Network Layer.
18 . The method as claimed in claim 17 wherein
the user terminal receives from the second network-access device an advertisement message containing information about an address of the second network-access device, and
the user terminal enters the address information in a routing table.
19 . The method as claimed claim 18 wherein
after the user terminal sends the request, the user terminal sends a device-specific request to a designated network-access device, and
the user terminal uses the address information of the second network-access device for device-specific request.
20 . The method as claimed in claim 19 wherein the user terminal uses the address information for setting up a connection to the second network-access device .
21 . The method as claimed in claim 20 wherein the connection transfer takes place between network-access devices supporting different standards on the Physical Layer.
22 . A user terminal comprising:
a receiver to receive signals transmitted on a Physical Layer from a first network-access device in a first connection;
a determination unit to determine a quality parameter based on the signals received a transmitter to send a request to the first network-access device and/or a second network-access device as a function of the quality parameter; and
an initiating unit to initiate a connection transfer to the second network-access device as a function of receiving an advertisement message from the first and/or second network-access device.
23 . The user terminal (MN) as claimed in claim 22 further comprising:
a controller to selectively forward advertisement messages received from the first network-access device to mobility-controlling mechanisms of a Network Layer as a function of the quality parameter, the mobility-controlling mechanisms controlling the connection transfer to the second network-access device.
