Explanation

Roaming in wireless networks follows a logical three-step sequence: the device first performs Roaming Measurements (A) - continuously sampling signal strength and quality from neighboring cells - then applies Roaming Judgment (C) to compare those measurements against thresholds and decide whether a handover is warranted, and finally carries out Roaming Execution (D) to complete the actual handover to the new cell or access point.

Option B (Roaming Identification) is the distractor. While subscriber/device identification does occur in some network authentication flows, it is not a discrete step within the roaming decision-and-handover process itself - it belongs to the broader network access or authentication layer, not the roaming procedure.

Memory tip: Think M → J → E ("My Judge Executes"): Measure the signal, Judge whether to roam, Execute the handover. Identification doesn't fit because you've already been identified before roaming decisions even begin.
