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 non-transitory computer-readable medium having computer-executable code stored thereon configured to acquire information of wireless serving systems from a communication station, comprising:

code for causing a system tag configured to include said information of said wireless serving systems to be provided, wherein the system tag includes a home system tag and a roaming system tag;

code for causing a message to be sent to said communication station for a system tag configuration; and

code for causing another message to be sent to said communication station for a system tag download, wherein the system tag download comprises a download of the home system tag and the roaming system tag.

2. The computer-readable medium as in claim 1, further including code for causing a computer to respond to messages sent by said communication station.

3. The computer-readable medium as in claim 2, further comprising code for causing additional information of said wireless serving system to be displayed in addition to a roaming status.

4. The computer-readable medium as in claim 3, further including code for causing specific information particular to said wireless serving system from said system tag based on the roaming indicator provided in said preferred roaming list to be displayed.

5. The computer-readable medium as in claim 3, further including code for causing the name of the network operator of said wireless serving system from said system tag based on the system identification provided in said preferred roaming list to be displayed.

6. The computer-readable medium as in claim 1, wherein:

the roaming system tag includes a group tag and a specific tag, and

the roaming system tag download comprises a group tag download and a specific tag download.

7. A non-transitory computer-readable medium having computer-executable code stored thereon configured to provide information of wireless serving systems to a communication terminal, comprising:

code for causing an inquiry corresponding to a capability of supporting a system tag which is configured to include said information of said wireless serving systems, wherein the system tag includes a home system tag and a roaming system tag;

code for causing a request message to be sent to said communication terminal for a system tag configuration; and

code for causing another request message to be sent to said communication station for a system tag download, wherein the system tag download comprises a download of the home system tag and the roaming system tag.

8. The computer-readable medium as in claim 7, wherein:

the roaming system tag includes a group tag and a specific tag, and

the roaming system tag download comprises a group tag download and a specific tag download.

9. A non-transitory computer-readable medium having computer-executable code stored thereon configured to ascertain a wireless serving system in a geographical location comprising:

code for causing a computer to provide a preferred roaming list which includes said wireless serving system;

code for causing a system tag which includes information of said wireless serving system to be provided, wherein the system tag includes a home system tag and a roaming system tag;

code for causing said wireless serving system in said geographical location to be ascertained by referring to said preferred roaming list, wherein at least one of the home system tag and the roaming system tag are downloaded based on said geographical location of said wireless serving system; and

code for causing information of said ascertained wireless serving system to be displayed based on said information of said wireless serving system from said system tag.

10. The computer-readable medium as in claim 9, wherein:

the roaming system tag includes a group tag and a specific tag, and

the roaming system tag download comprises a group tag download and a specific tag download.
