SCKL format

Why use SCKL?

Not all networks, for example CDMA, iDEN and TDMA networks, can directly pass binary data to mobile phones. Ringtones and graphics contain binary data and Nokia's SCKL encoding provides a method of delivering binary data to a phone using only printable characters. Thus it allows ringtones and graphics to be delivered over CDMA, iDEN and TDMA networks. Clearly it also requires a phone that can correctly interpret the SCKL format and most Nokia phones can do this, as well as some phones from other manufacturers and many WAP compatible phones.

The SCKL encoding can be used in CDMA, GSM, iDEN and TDMA environments.

What is the format of an SCKL message

SCKL message consists of a Header then a space and lastly User Data. Please note that the description that follows is somewhat simplified to give all the essentials without giving all the options. You should find the information here is sufficient in practice. Here is a SCKL format message to send a ringtone:

//SCKL1581 024A3A650995D1D195C93D999804144288F511610611624D30831445

Each SCKL message must contain 160 characters or less since this is the maximum number of characters that can be sent in one SMS message. The letters must be in UPPER CASE for some phones.

You can send an SCKL message to any CDMA, GSM, iDEN or TDMA phone as a standard text message from this website by cutting and pasting it into the text entry box - see "Send SMS" in the Navigation Bar above.

Header

The shortest Header consists of the string //SCKL followed by the 4 character Port Number (e.g. 1581) giving the complete header as //SCKL1581

If the User Data and Header cannot fit into a single SMS message then it can be split over two or three messages. The User Data is said to be split into segments and in this case the Header consists of:

  • the string //SCKL followed by
  • the 4 character Port Number (see below for details of Port Numbers)
  • the 4 character Port Number (again)
  • 2 digit arbitrary reference number which must be the same for all parts of the message
  • 2 digits giving the total number of segments used to send the User Data
  • 2 digits giving the number of this segment

For example //SCKL15811581990301 for the first segment of three, //SCKL15811581990302 for the second segment etc.

Note that the maximum number of segments allowed is specified as three - despite 2 digits being required to hold the value! The segment count will thus be either 01, 02 or 03. In reality more than three segments are supported by some phones. See below for more complete examples of multi-segment messages.

When creating messages with large User Data, it is important to remember that some mobile phones do not support message concatenation although most new mobile phones do. These devices might truncate the header or omit the segmentation and reassembly part of the header - in other words they won't work as hoped.

Wireless Datagram Protocol - WDP

Services using WDP (such as smart messaging) can be adapted to work over a variety of network technologies (including CDMA, GSM, iDEN and TDMA). This is accomplished by defining port numbers that are specifically reserved for particular services or application protocols. In other words, each port number has a specific exchange format associated with it.

The WDP port numbers are approved by the Internet Association Numbering Authority (IANA) and used by the WAP Forum as shown below.

Dealing with binary data

vCard and vCalendar items will often only contain ASCII characters which is the default character set for vCard and vCalendar items. The default character set can be overridden for an individual property value by using the “CHARSET” property parameter.

Ringtones, Operator logos and Group Graphics contain binary data which must be converted to Hexadecimal format before it is sent. Some code snippets for doing this are available on this website as is a "drag and drop" Windows application.

Examples of SCKL encoded data

Most importantly remember that the Header must be separated from the User Data by a space character. In order to emphasize this the following examples show <space> for the space character.

A Ring Tone

The following is an example of a ringtone called "Better off alone". If you are cutting and pasting don't forget to replace the <space> with a space character! In order to display this on the web page each SMS message has been split over 2 lines but in practice must consist of a single line of data.

//SCKL1581<space>024A3A650995D1D195C93D999804144288F511610611624D3083
14458418458418938C20C30C5186108186108156

Here is another called "2 times". Notice that this ring tone has been divided into two message segments and must be sent as two SMS messages.

//SCKL15811581010201<space>024A3A58C951A5B595CC0414491E934C511624D31
4458934C511624D40830840D40830840

//SCKL15811581010202<space>D30DB0D30DB0D408308

For more information on ring tone encoding, refer to the Nokia Smart Messaging Specification 3.0.0. The User Data is not RTTTL data - the process of converting from RTTTL data to Nokia ringtone format is quite complicated.

A Group Graphic or CLI Icon

The following is an example of a Caller Line ID (CLI) Icon. Nokia Group Graphics have a maximum size of 72 by 14 pixels and the encoded data needs two SMS message. In order to display this on the web page each SMS message has been split over 2 lines but in practice must consist of a single line of data.

//SCKL15831583660201<space>3000480E01FFFFFFFFFFFFFFFFFF80000180000300000183FFC183

F80180F80180F80301F00181F00181F00303E001800001800003000001FFFFFFFFFFFFFFFFFF

For more information on how to encode an Group Graphic refer to Sections 3.7 and 5.1.7 of the Nokia Smart Messaging Specification 3.0.0 - it is a little bit more complicated that just putting the image data directly in as User Data.

An Operator Logo

The following is an example of an operator logo for Vodafone UK with MCC=234 and MNC=15. MCC and MNC values are shown in our Global Coverage pages. Nokia Operator Logos are normally a 72 by 14 pixel image and the encoded data needs to be split over three SMS messages. In order to display this on the web page the strings have been split over 2 lines but in practice each must consist of a single line of data. Yes it is the same image as used above for the Group Graphic!

//SCKL15821582770201<space>3032F4510A00480E01FFFFFFFFFFFFFFFFFF800001800003000001

For more information on how to encode an Operator Logo refer to the Nokia Smart Messaging Specification 3.0.0 - it is a little bit more complicated that just putting the image data directly in as User Data.

A vCard

The following is an example of an electronic business card or vCard. The default character set is ASCII. The default character set can be overridden for an individual property value by using the “CHARSET” property parameter.

If the vCard message content is

BEGIN:VCARD
FN:Support
TEL;PREF:+44207713800
END:VCARD

The SCKL format message would be as shown below. Note that <CR> indicates a Return character and <LF> a Line Feed character.

//SCKL23F4<space>BEGIN:VCARD<CR><LF>
FN:Support<CR><LF>
TEL;PREF:+442077138000<CR><LF>
END:VCARD<CR><LF>

vCard version 3 is defined in two parts: RFC 2425, MIME Content-Type for Directory Information and RFC 2426, vCard MIME Directory Profile.

The Internet Mail Consortium has taken on responsibility for the development and promotion of the vCard format. Their website contain useful documents for developers.

For Nokia specific implementation see Sections 3.4 and 5.1.3 of the Nokia Smart Messaging Specification 3.0.0.

A vCalendar entry

The following is an example of an electronic business card or vCalendar. The default character set is ASCII. The default character set can be overridden for an individual property value by using the “CHARSET” property parameter.

If the vCalendar message content is

BEGIN:VCALENDAR
VERSION:1.0
BEGIN:VTODO
SUMMARY:www.csoft.co.uk re SMS
DUE: 20120207 T101500
STATUS:NEEDS ACTION
END:VTODO
END:VCALENDAR

The SCKL format message would be as shown below. Note that <CR> indicates a Carriage Return character and <LF> a Line Feed character.

//SCKL23F5 BEGIN:VCALENDAR<CR><LF>
VERSION:1.0<CR><LF>
BEGIN:VTODO<CR><LF>
SUMMARY:www.csoft.co.uk re SMS<CR><LF>
DUE: 20120207 T101500<CR><LF>
STATUS:NEEDS ACTION<CR><LF>
END:VTODO<CR><LF>
END:VCALENDAR<CR><LF>

The Open Standards version of vCalendar is known as iCalendar. iCalendar consists of three RFC's: RFC 2445, Internet Calendaring and Scheduling Core Object Specification (iCalendar), RFC 2446, iCalendar Transport-Independent Interoperability Protocol (iTIP): Scheduling Events, BusyTime, To-dos and Journal Entries and RFC 2447, iCalendar Message-based Interoperability Protocol (iMIP)

The Internet Mail Consortium has taken on responsibility for the development and promotion of the iCalendar format. Their website contain useful documents for developers.

For Nokia specific implementation see Sections 3.5 and 5.1.4 of the Nokia Smart Messaging Specification 3.0.0.
