Character enablement in short message service
View Patent ↗A method is provided for encoding characters that specify a source address of an SMS message. The method comprises modifying a type of address field within an originating address field, the modification indicative of an encoding scheme used for the source address of the SMS message.
1. A network component, comprising:
a processor configured to:
provide a first indicator in an originating address field of a short message service (SMS) message, the first indicator indicating an alternative encoding scheme is used for a source address of the SMS message and a location of a second indicator indicating the alternative encoding scheme,
wherein the alternative encoding scheme is Universal Character Set (UCS2)-based encoding National Language table-based encoding;
encode the source address using the alternative encoding scheme; and
transmit the SMS message with the first indicator, the second indicator, and the encoded source address;
wherein the first indicator comprises a binary value indicating that the location of the second indicator is an extension portion that specifies which of the alternative encoding schemes is to be used, and
wherein the extension portion is:
an octet following the type of address field; or
a new information element in the SMS message body.
2. The network component of claim 1 , wherein the second indicator comprises a binary value.
3. The network component of claim 1 , wherein the extension portion replaces a numbering plan identification portion of the originating address field.
4. The network component of claim 1 , wherein the first indicator comprises a binary value indicating that the encoding scheme is located in a numbering plan identification portion of the originating address field.
5. The network component of claim 1 , wherein information related to the source address is included in an information element in the SMS message body, the information related to the source address being encoded using one of:
a Global System for Mobile communications (GSM) default alphabet;
Universal Character Set (UCS2)-based encoding; and
National Language table-based encoding.
6. The network component of claim 1 , wherein information related to the source address is included in a reserved string in the SMS message body, the information related to the source address being encoded using one of:
a GSM default alphabet;
Universal Character Set (UCS2)-based encoding; and
National Language table-based encoding.
7. A mobile device, comprising:
a processor configured to:
receive an originating address field in a short message service (SMS) message, the originating address field including a first indicator, the first indicator indicating an alternative encoding scheme is used for a source address of the SMS message and a location of a second indicator indicating the alternative encoding scheme,
wherein the alternative encoding scheme is Universal Character Set (UCS2)-based encoding National or Language table-based encoding;
decode the source address based on the second indicator and the alternative encoding scheme,
wherein the first indicator comprises a binary value indicating that the location of the second indicator is an extension portion that specifies which of the alternative encoding schemes is to be used, and
wherein the extension portion is:
an octet following the type of address field; or
a new information element in the SMS message body.
8. The mobile device of claim 7 , wherein the second indicator comprises a binary value indicating which of the alternative encoding schemes is to be used.
9. The mobile device of claim 7 , wherein the extension portion replaces a numbering plan identification portion of the originating address field.
10. The mobile device of claim 7 , wherein the first indicator comprises a binary value indicating that the encoding scheme is located in a numbering plan identification portion of the originating address field.
11. The mobile device of claim 7 , wherein information related to the source address is included in an information element in the SMS message body, the information related to the source address being encoded using one of:
a Global System for Mobile communications (GSM) default alphabet;
Universal Character Set (UCS2)-based encoding; and
National Language table-based encoding.
12. The mobile device of claim 7 , wherein information related to the source address is included in a reserved string in the SMS message body, the information related to the source address being encoded using one of:
a GSM default alphabet;
Universal Character Set (UCS2)-based encoding; and
National Language table-based encoding.
