Mobile message type specification - Operator logo SMS, binary
(SMS message type, SMS message format)
Introduction
Operator logos are graphical images that are displayed on a phone when the phone signs into a GSM network. An operator logo is identified by a country code and a mobile network code. GSM handsets supporting this technology can store more than one image at a time, and when the handset roams between networks, it can display the appropriate operator logo.
An operator logo is an OTA bitmap. The OTA bitmap is a black and white picture with a gray scale level of 1 to 255. The OTA bitmap has a header and a body. The header has a predefined width and a height field specifying how the stream of bits in the body should be broken into lines.
When designing operator logos, the designer has to keep in mind that different handsets support operator logos of different dimensions. The most common bitmap size for operator logos is 72x14 pixels. Other ota picture messages can have a dimension of 72x28 pixels.
Support for operator logos in Ozeki NG - SMS Gateway
To build an operator logo, you have to encode it in a binary format. This format contains a header and a body. The header specifies the operator logo version number, the Mobile Country Code (MCC) and the Mobile Network Code (MNC) fields in addition to the dimensions and the color depth of the bitmap. The body holds the OTA bitmap.

Sending an operator logo in SMS
To send an operator
logo message with Ozeki NG - SMS Gateway, you need to specify a message
type which tells the software that the following message is an operator logo.
To send the above example, you would use the following message type:
SMS:OPLOGO
In this case, the message type is
made up of two sections. The first section tells the message server that this
is an SMS message. This way only the
service provider connections
supporting this type of SMS will
be considered to deliver the message. The second section is used by the
service provider to use the
operator logo encoder. This encoder will create the protocol data unit (PDU)
that will be sent as an SMS message.
Example:
If you use the Database
user to send and receive SMS messages with Ozeki NG - SMS Gateway, you
can use the following SQL statement to send an Operator Logo message:
insert into
ozekimessageout
(receiver,msgtype,msg,status) values
('+36205222245','SMS:OPLOGO',
'3021F3540A00480E01FF...001','send');
