Abstract
Subscriber units (14) can roam from zone (A) to zone (B) and accurately compile fragments of a message that includes fragments transmitted from both zones. Preferably, a subscriber unit (14) assigns different markers to fragments received from different zones. When the subscriber unit senses that a received message includes fragments from different zones, it correlates a number of characters of a fragment received from one zone (A) to a similar number of characters in a fragment received from a different zone (B). If a complete match is not found, the fragments are combined as part of a message. If a match is found, a further comparison looks for additional matches between fragments and, finding such additional matches, erases one copy of duplicate characters.
