BASE STATION CACHING FOR AN EFFICIENT HANDOVER IN A MOBILE TELECOMMUNICATION NETWORK WITH RELAYS |
摘要 |
It is described a method for transferring data in a downlink direction from a transmitting network element to a user equipment. The described method includes (a) sending at least one data packet from the transmitting network element to a source base station, (b) receiving the data packet by the source base station, which is connected to a source relay node representing a source access point for the user equipment, (c) caching the data packet by the source base station, (d) handing over the user equipment from the source relay node to a target access point, and (e) transferring the data packet from the source base station via the target access point to the user equipment. It is further described a corresponding method for transferring data in an uplink direction from a user equipment to a receiving network element, wherein the caching is carried out by a target base station. Furthermore, it is described a source base station and a target base station, which are adapted to carry out respectively one of the above mentioned data transferring methods. |
