Abstract

A system and method for optimizing handover parameters for a plurality of mobile terminals on a common transportation platform in a cellular network includes at least a first terminal and a second terminal and a controller. The controller is configured to determine that each of the first and second terminal are on the common transportation platform, monitor a status of a handover attempt of the first terminal, and if the handover attempt is successful, adopt handover parameter settings of the first terminal for the second terminal, and if the handover attempt is not successful, change handover parameter settings for the second terminal.

Claims

1. A system for optimizing handover parameters for a plurality of mobile terminals on a common transportation platform in a cellular network, the system comprising:

a first mobile terminal and a second mobile terminal; and

a controller, the controller being configured to;

determine that each of the first mobile terminal and the second mobile terminal is on the common transportation platform;

monitor a status of a handover attempt of the first mobile terminal;

control and adjust parameters for handover procedure of the first mobile terminal and the second mobile terminal;

if the handover attempt of the first mobile terminal is successful, adopt a handover parameter setting of the first mobile terminal for the second mobile terminal; and

if the handover attempt of the first mobile terminal is not successful, change a handover parameter setting for the second mobile terminal.

2. The system of claim 1, further comprising a short range communication device on the common transportation platform, the short range communication device being configured to transmit information to and receive information from the first mobile terminal and the second mobile terminal over a short distance.

3. The system of claim 2, wherein the short range communication device is further configured to transmit information to the cellular network via a cellular radio link between the common transportation platform and the cellular network.

4. The system of claim 2, wherein the short range communication device is further configured to transmit to each mobile terminal of the plurality of mobile terminals on the common transportation platform at least one of the following:

an identifier of the common transportation platform, and an identifier of the short range communication device.

5. The system of claim 2, wherein the short range communication device is further configured to transmit an identifier of each of the first mobile terminal and the second mobile terminal to the cellular network via a cellular radio link between the common transportation platform and the cellular network.

6. The system of claim 2, wherein the short range communication device is part of an access point of a local area network on the common transportation platform.

7. The system of claim 2, wherein the short range communication device is part of a relay station of the cellular network.
