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 computer program product for acquiring information of wireless serving systems from a communication station, comprising:

computer-readable medium comprising;

code for causing a computer to provide a system tag 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 computer to send a message to said communication station for a system tag configuration; and

code for causing a computer to send another message to said communication station for a system tag download, wherein the system tag download comprises said communication station downloading 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.

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

6. The computer-readable medium as in claim 5, further including code for causing a computer to display specific information particular to said wireless serving system from said system tag based on the roaming indicator provided in said preferred roaming list.

7. The computer-readable medium as in claim 5, further including code for causing a computer to display 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.

3. A computer program product configured to provide information of wireless serving systems to a communication terminal, comprising:

computer-readable medium comprising;

code for causing a computer to inquire from said communication terminal on the 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 computer to send a request message to said communication terminal for a system tag configuration; and

code for causing a computer to send another request message to said communication station for a system tag download, wherein the system tag download comprises said communication station downloading the roaming system tag.

4. A computer program product, configured to ascertain a wireless serving system in a geographical location comprising:

computer-readable medium comprising;

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

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

code for causing a computer to ascertain said wireless serving system in said geographical location by referring to said preferred roaming list, wherein either the home system tag or the roaming system tag is downloaded based on said geographical location of said wireless serving system; and

code for causing a computer to display information of said ascertained wireless serving system based on said information of said wireless serving system from said system tag.
