Abstract:
1. A method in a network entity of a wireless communication system for selection of a backhaul path to a core network for a first radio base station that provides direct wireless access to user terminals, wherein the first radio base station has access to a first backhaul path to the core network through an out-of-band interface and access to at least one second backhaul path to the core network, via at least one second radio base station, through an in-band interface, the method comprising: sending, to the at least one second radio base station, a request for available capacity on the at least one second backhaul path for backhauling through the in-band interface of the first radio base station, wherein the request includes information about the first backhaul path; receiving, from the at least one second radio base station, at least one response including information on a total available capacity on the at least one second backhaul path to the core network through the in-band interface for backhauling of the first radio base station, wherein said total available capacity has been derived from an estimate of available capacity for backhauling on a backhaul path from the at least one second radio base station to the core network and from an estimate of available capacity for backhauling on the in-band interface; and selecting the first backhaul path to the core network through the out-of-band interface or one of the at least one second backhaul path to the core network through the in-band interface for a portion of traffic based on the received information on the available capacity on the at least one second backhaul path for backhauling of the first radio base station that provides direct wireless access to the user terminals.
