Handover Gaps After a Vendor Swap: What Service Teams Should Check First

Vendor swaps reset many of the dashboards service teams rely on. Neighbour lists, measurement reporting, and even the names of familiar counters can shift. Complaints, however, arrive in the same language: calls that fall on a particular bridge, data that stalls inside a mall, or voices that chop along a known commute.

In the first fortnight, prioritise handover and reselection behaviour on the corridors your desk already knows. Walk or drive a small set of routes with a measurement handset and note where the serving cell changes later than the geography suggests. Those delayed handovers often explain the choppy voice reports before any deep optimisation campaign begins.

Compare those notes with the new vendor’s neighbour configuration for the same sectors. Misaligned neighbours after a swap are common enough that a short Coverage Walk Review can save days of remote speculation.

Document every confirmed gap with a photo of the street context and a timestamp. When the optimisation vendor asks for evidence, that packet travels faster than a thread of chat messages.
