HANDOVER FAILURE DETECTION DEVICE, HANDOVER PARAMETER ADJUSTMENT DEVICE, AND HANDOVER OPTIMIZATION SYSTEM |
摘要 |
A handover failure detection device (121) detects at least one of handover failure types regarding outgoing handover from a first cell (131) managed by a first base station (111) by observing: (a) presence/absence of reception by the first base station (111) of a handover completion notification regarding first handover of a mobile terminal (101) from the first cell (131) to a second cell (132) managed by a second base station (112); and (b) presence/absence of a request for connection re-establishment from the mobile terminal (101) to the first cell (131), the request occurring after initiation of the first handover. As a result, it contributes to improvement of handover failure detection or reduction of handover failure in a situation where exchange of information between at least some of base stations has been limited. |
