Interface Establishment between Access Nodes of Different Radio Access Technologies

摘要

The present disclosure relates to a method performed in a first access node in a wireless network of establishing a communications interface between the first access node arranged to operate according to a first radio access technology and one or more second access nodes arranged to operate according to a second radio access technology. The one or more second access nodes are discovered (S31) based on receipt of respective radio signals representative of each second access node. A second access node of the discovered one or more second access nodes is selected (S32) for establishing a communications interface with. A transport address is derived (S33) for the selected second access node from a node related identity retrieved in the radio signal and an interface setup request message is sent (S34) to the selected second access node. The communications interface is established upon receipt (S35) of an interface setup response message from the selected second access node.
