CONTROL APPARATUS, BASE STATION APPARATUS, RADIO TERMINAL, AND METHOD FOR UPDATING NEIGHBOUR RELATION TABLE

摘要

A control apparatus (1) is configured to automatically update a neighbour relation table (40, 131) of a source cell (10A). The control apparatus (1) is further configured to add, to the neighbour relation table (40, 131), a new entry (41) indicating a neighbour-cell relation from the source cell (10A) to another cell (10B) different from both the source cell (10A) and a target cell (10C) of a handover from the source cell (10A), in response to receiving a first message (S105) that is issued when a radio terminal (2) that has experienced a failure involving disconnection of a radio link connection in the source cell (10A) or in the target cell (10C) attempts to re-establish the radio link connection to the other cell (10B). This contributes to updating the neighbour-cell relations in response to detection of a handover failure.

主权项

1. A control apparatus comprising:
at least one memory configured to store a set of instructions and a neighbour relation table including a plurality of entries indicating a neighbour-cell relations from a source cell to respective neighbour cells; and at least one processor configured to execute the set of instructions to automatically update the neighbour relation table, wherein the set of instructions further causes the at least one processor to add, to the neighbour relation table, a new entry indicating a neighbour-cell relation from the source cell to another cell different from both the source cell and a target cell of a handover from the source cell, in response to receiving a first message that is issued when a radio terminal that has experienced a failure involving disconnection of a radio link connection in the source cell or in the target cell attempts to re-establish the radio link connection to the other cell.
