Patent ID: 7991398

Claim:
A method for providing diversity handover, DHO, related instructions to a first DHO tree node that is a part of or is planned to be a part of a DHO connection in a mobile telecommunication network, wherein the DHO functionality is distributed to one or a plurality of DHO nodes, including a Radio Network Controller (RNC) and its connected Node Bs, in the network, the method comprising: a DHO node including in a first signaling message one or more transport layer addresses and one or more transport bearer reference parameters in order to direct one or more data flows between the RNC and a mobile station of the DHO connection, and the DHO node sending the first signaling message to the first DHO tree node, wherein the DHO functionality performed by the first DHO tree node comprises splitting of downlink data flows and combining of uplink data flows, wherein the first DHO tree node is separate from the RNC, and wherein the including-step comprises replacing the transport layer address and transport bearer reference parameter of the RNC by transport layer address and transport bearer reference parameter of a DHO tree node that is hierarchically higher than the first DHO tree node in a regular signaling message sent to the first DHO tree node in order to direct a data flow between the first DHO tree node and the higher DHO tree node in a DHO tree node hierarchy.
