Telecommunications handover when Handover Restriction List is missing

摘要

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).

1. A base station node of a radio access network comprising:
a communication interface to a higher layer network node; a handover unit configured to request that the higher layer network node make a decision regarding a target cell to which to handover a particular wireless terminal when the base station node does not have roaming configuration information for the particular wireless terminal, the target cell being shared by plural public land mobile networks; and wherein the handover unit is configured: to determine whether there is a handover restriction list (HRL) for the particular wireless terminal; when there is no handover restriction list (HRL) for the particular wireless terminal, to request that the higher layer network node make a selection of one of the plural public land mobile networks for the target cell.
