Abstract

A base station node (26S) of a radio access network comprises a communication interface (62) to a higher layer network node (40) and a handover unit (50). The handover unit (50) is configured to request that the higher layer network node (40) make a decision regarding a target cell (28T) to which to handover a particular wireless terminal (30) when the base station node does not have roaming configuration information for the particular wireless terminal and an attempted X2 interface handover of the particular wireless terminal has failed. The target cell (28T) is of a type that is shared by plural public land mobile networks (42, 44).
