Abstract

A method and radio base station for enabling establishment of backhaul links. A method is performed by a first communication network node for establishing a backhaul link (BH) between the first communication network node and a second communication network node (200, 200′, 202, 400), wherein one of the first communication network node and the second communication network node is associated to a backhaul network (220). The second communication network node is detected (500), an address of the second communication network node is determined (502), preferably, an IP-address or an Ethernet-address. The address is sent (504) to a backhauling entity (206), the backhauling entity being associated with a third communication network node (204), and at least one of the first communication network node and the second communication network node is located within a coverage of the third communication network node. Routing information regarding the second communication network node is received (506) from the backhauling entity, the routing information being calculated by the backhauling entity, and a backhaul link (BH) between the first communication network node and the second communication network node is established (508) by applying the routing information. By performing routing calculations in a central backhauling entity, embedded RBSs may be designed less complex because less calculation capacity needs to be included, and no routing protocols needs to be stored locally. Moreover, the backhauling entity may select the most appropriate and effective transport mechanism for the backhauling.
