Abstract
Techniques for downloading and displaying system tags by wireless terminals based on roaming status. A tag includes texts and/or graphics. The system tags include home system tags and roaming system tags, which include group tags and specific tags. A home system tag is associated with one or multiple home systems, a group tag is associated with one or multiple roaming indicator values, and a specific tag is associated with one or multiple SID values. A terminal is provided with home system tag, group tags, and specific tags. The terminal displays the home system tag when obtaining service from the home system and a roaming system tag when obtaining service from a roaming system. The particular roaming system tag to be displayed is dependent on the roaming indicator value and the SID value for the roaming system. The system tags may be downloaded to the terminal via over-the-air signaling.
