Methods of Facilitating the Handover of a User Equipment, UE, in a Telecommunication Network from a Base Station to a Relay Node, as well as Corresponding Nodes and Modules

A method of handing over a User Equipment, UE, in a telecommunication network from a base station to a relay node, which relay node is arranged to relay traffic between a UE and said base station, wherein said method comprises the steps of:

• receiving, by said relay node, from said base station a request for handing over said UE connected to said base station;
• characterized by the steps of:
• transmitting, by said relay node, a QoS query request to a QoS Status module for querying whether a QoS parameter of said UE is below a QoS threshold for said relay node;
• receiving, by said relay node, from said QOS Status module a QoS query acknowledgement thereby acknowledging that said QoS parameter of said UE is below said QoS threshold for said relay node;
• transmitting, by said relay node, to said base station, based on said QoS query acknowledgement, a handover acknowledgement message thereby acknowledging the handover of said UE from said base station to said relay node.

A relay node for facilitating the handover of a User Equipment, UE, in a telecommunication network from a base station to a relay node, which relay node is arranged to relay traffic between a UE and said base station, wherein said relay node comprises:

• receive equipment arranged for receiving, from said base station a request for handing over said UE connected to said base station;
• characterized in that the relay node further comprises:
• transmit equipment arranged for transmitting, to a QoS status module, a Quality of Service, QoS, query request for querying whether a QoS parameter of said UE is below a QoS threshold;
• said receive equipment being further arranged for receiving, from said QoS status module, a QoS query acknowledgement thereby acknowledging that said QoS parameter of said UE is below said QoS threshold;
• said transmit equipment being further arranged for transmitting, to said base station, based on said QoS query acknowledgement, a handover acknowledgement message thereby acknowledging the handover of said UE from said base station to said relay node.
