During the hard handover procedure for inter-frequency, when the UE is moving away from HNB coverage area, HNB will receive the event 2D when quality of the currently used frequency is below the 2D threshold configured. When the event 2D is triggered, compressed mode scanning will be started. If the UE moves further away and satisfy the event 2B condition when estimated quality of the currently used frequency is below the 2B threshold configured and estimated quality of the non-used frequency is above the configured threshold. Event 2B will trigger the handover procedure.
However if the Event 2D threshold is met and compressed mode measurement reporting is started but UE is moving towards the HNB coverage area and the estimated quality of the currently used frequency is better than the configured 2F threshold, UE will exit the compressed mode.
very well said. Thanks !!
ReplyDeleteI have a query, when NW should assist UE to perform, event 2B measurements ?
How the NW takes decision to perform e2B measurement ?
I believe NW means network listen. If true, I did understand the question. Happy to answer if you post it clearly.
ReplyDeleteI did not notice this again since some how did trigger flag on this comment.
Liked the approach. Thank you
ReplyDeleteboas caros,
ReplyDeletepoderiam me explicar o que é o compress mode?
