Abstract
The present invention relates to methods and arrangements in a wireless communication system that enable a load balancing procedure in a network with HeNB GWs. The problem of the ineffective conventional load balancing procedure when used in a network with HeNB GWs, is addressed by a solution where the HeNB includes (510) an explicit indication of the reason for radio link establishment (load balancing establishment cause) in the S1AP INITIAL UE MESSAGE message (511) used to establish the S1 signaling connection associated with a user equipment to an MME, so that the HeNB GW (550) can perform an accurate MME selection based on the knowledge that the establishment is due to load balancing, i.e. an MME selection that realizes the required inter-MME load balancing.
