Communication device and method therein for handover in wireless communication network
First Claim
1. A method performed in a communication device for handover from a serving cell to a target cell in a communication network, the method comprising:
- obtaining a first round trip time between the communication device via a serving node in the serving cell and a server;
obtaining a second round trip time between the communication device via a target node in the target cell and the server; and
conditionally sending to the serving node, based on a consideration of at least the first round trip time and the second round trip time, a request for handover from the serving cell to the target cell,wherein conditionally sending, based on a consideration of at least the first round trip time and the second round trip time, a request for handover from the serving cell to the target cell further comprises;
sending a request for handover from the serving cell to the target cell if the first round trip time is larger than the second round trip time.

Abstract
A communication device and method therein for handover from a serving cell to a target cell in a communication network are disclosed. The communication device is configured to obtain a first round trip time between the communication device via the network node and a server and obtain a second round trip time between the communication device via a target node in the target cell and the server. The communication device is further configured to send a request for handover from the serving cell to the target cell based on at least the first round trip time and the second round trip time.

19. A method performed in a communication device for handover from a serving cell to a target cell in a communication network, the method comprising:
-
obtaining a first round trip time between the communication device via a serving node in the serving cell and a server; obtaining a second round trip time between the communication device via a target node in the target cell and the server; and conditionally sending to the serving node, based on a consideration of at least the first round trip time and the second round trip time, a request for handover from the serving cell to the target cell, wherein conditionally sending, based on a consideration of at least the first round trip time and the second round trip time, a request for handover from the serving cell to the target cell further comprises; sending a request for handover from the serving cell to the target cell if the second round trip time is larger than the first round time but lower than a pre-determined threshold and a signal quality of the target cell is better than the serving cell.
