Geo Cache

The memory of the positioning: which radio environments are already known, which position applies to each, and how often an entry has already matched.

  • See what the application has learned

  • Understand how reliable an entry is

  • Remove wrong entries so the environment is learned again

Why This View Exists

The cache saves chargeable requests: once an online service has resolved a radio environment, it is recognized later. How this works is described in How a Position is Determined.

The cache applies across all tenants — a mobile network cell is at the same place regardless of who observes it. That is deliberate and has a downside: a wrong entry distorts the positions of every tenant. That is why it is maintained centrally rather than per tenant.

Reading Exact Hits and Best Hits

The distinction is the actual diagnostic tool of this view.

Observation Interpretation

Mostly Exact Hits

A stable environment. The entry is reliable

Mostly Best Hits

The environment changes frequently — or the entry is too broad and matches where it should not

Very many hits overall

An important entry. Removing it will first cause new requests at the online service

An entry with no access points

It applies to the cell alone and therefore to a large area. The position is correspondingly coarse

Deleting Entries

Select one or more entries and delete them. A confirmation is required, since the action cannot be undone.

What happens afterwards: the next report from that environment is looked up at the online service again, and the result is stored anew. A wrong entry is thereby permanently resolved — provided the cause was in the cache and not in a wrongly recorded position of your own.

Check first in Decision events (Administration) whether the wrong position really came from the cache. The detail dialog names the source. If it came from a recorded position of your own, deleting a cache entry changes nothing.

When No List Appears

If instead of the entries a notice appears stating that the cache provider does not support listing, the installation runs a cache variant without that capability. The cache still works normally but cannot be inspected or cleaned up individually.
