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.

Claims

1. A method of displaying system tags by a wireless terminal, comprising:

determining if a serving system for the terminal is one of at least one home systems for the terminal;

it the serving system is one of the at least one home systems;

displaying a home system; and

if the serving system in not one of the at least one home systems;

determining availability of a roaming system tag for the serving system by including ascertaining a system identification (SID) and a roaming indicator value for the serving system, and further by including ascertaining whether the SID value for the serving system is included in a set of SID values for which roaming system tags are available; and

displaying the roaming system tag associated with the SID value of the serving system if available;

wherein the determining further including ascertaining a roaming indicator value for the serving system, and further including ascertaining whether the roaming indicator value for the serving system is included in a set of roaming indicator values for which roaming system tags are available, and wherein the roaming system tag associated with the roaming indicator value for the serving system is displayed if available and if the roaming system tag associated with the SID value for the serving system is not available.

2. A method of downloading system tag information in a wireless communication system, comprising:

receiving a first message requesting current configuration information for system tags stored by a terminal, wherein the system tags are suitable for display based on roaming status of the terminal, and wherein the system tags stored by the terminal include at least one home system tag and at least one roaming system tag, and wherein each of the system tags is associated with one or more systems, the at least one roaming system tag includes at least one group tag and at least one specific tag, wherein each of the at least one group tag is associated with one or more roaming indicator values, and wherein each of the at least one specific tag is associated with one or more system identification (SID) values;

sending a second message with the requested current configuration information; and

receiving a third message for at least one system tag to be downloaded to the terminal.

3. The method of claim 2, wherein the at least one group tag is included in a first list and the at least one specific tag is included in a second list.

4. The method of claim 3, wherein an entire list of one or more group tag is downloaded to the terminal if selected, and wherein an entire list of one or more specific tags is downloaded to the terminal if selected.
