DISTRIBUTED UNIT, PROXY CENTRAL UNIT AND METHODS IN A WIRELESS COMMUNICATIONS NETWORK

摘要

Embodiments herein relate to a method performed by a distributed unit (300B) of a network node (300), for establishing a connection between the distributed unit and a central unit (300A) connected to a core part of the wireless network. The network node comprises the central unit and at least said distributed unit. The distributed unit performs a Domain Name Server (DNS) lookup for a proxy central unit (300D), which will act as a temporary or initial central unit with regard to a configuration transfer procedure. The distributed unit further receives an ip address of the proxy central unit and initiates the configuration transfer procedure by sending a configuration transfer message to the ip address of the proxy central unit. The distributed unit further receives an ip address of the central unit and establishes a connection between the distributed unit and the central unit using the received ip address of the central unit.
