Tengfei, 

Trying to understand you point about " handle Sixtop ADD Response with return code SUCCESS but 0 cells in cellList " 

If the response code is SUCCESS, IMO that means option 1. if option 2 is happening (I assume you mean "there is no memory for allocating more cells"), I would expect another return code, no? 

THomas

> - handle Sixtop ADD Response with return code SUCCESS but 0 cells in cellList

> There are two possible reason for this situation
> 1. the proposed celllist doesn't meet the requirement from neighbor side
> 2. there is schedule memory for adding more cells.

> For the 1st reason, the node may try to send another 6P request later.
> For the 2nd reason, the node may switch to another parent but it's layer
> violated.

> Any solutions for this case?
