What is SMS encoding?
Answer. Messaging encoding is how your text message is sent to the mobile phone carriers. The type of encoding used influences how many characters can be used in each message segment.
What is a data Coding Scheme?
Data Coding Scheme is a one-octet field in Short Messages (SM) and Cell Broadcast Messages (CB) which carries a basic information how the recipient handset should process the received message. The information includes: the character set or message coding, which determines the encoding of the message user data.
What is DCS in message?
In SMPP, the data coding scheme (DCS) indicates information that includes (but isn’t restricted to) the character set that the message text is in.
Why are coding schemes necessary?
The coding scheme is a Standard which tells the user’s machine which character represents which set of bytes. Specifying the coding scheme used is very important as without it, the machine could interpret the given bytes as a different character than intended.
How are SMS messages encoded?
GSM-7 is a character encoding standard used for commonly used letters and symbols in many languages. It uses 7 bits to send a single character/symbol on GSM networks. As SMS messages are transmitted as 140 8-bit octets at a time, GSM-7 encoded SMS messages can carry up to 160 characters (140*8/7=160).
What is GSM-7 encoding?
What is SMS format?
Short Message Service or SMS messages, as defined in RFC 5724, are short two-way alphanumeric paging messages that can be sent to and from SMS clients. One of the defining characteristics of SMS messages is the maximum length of 160 7-bit characters (140 octets).
How many characters are in a UCS-2 message?
The Basics of UCS-2 Encoding and SMS Messages. UCS-2 is a fixed-width encoding; each encoded code point will take exactly 2 bytes. As a SMS message is transmitted in 140 octets, a message which is encoded in UCS-2 has a maximum of 70 characters (really, code points): (140*8) / (2*8) = 70.
Why is UCS-2 used on the GSM networks?
Why is UCS-2 Used on the GSM Networks when GSM-7 is the Default Alphabet? In some languages, more than 128 symbols are commonly used, so a larger universe of potential characters is needed. UCS-2 has been implemented in many GSM networks and on many mobile devices, and is considered the defacto standard fallback.
What does DCS 246 stand for in GSM?
DCS 246 — SIM-specific binary message. This is only used in special cases where you are communicating with a custom application on the mobile device. No message reaches the phone’s SMS inbox. The characters not present in the GSM character set are shown on a grey background.
How does bandwidth encode its SMS messages?
Yes, Bandwidth uses UCS-2 which can encode anything in the Basic Multilingual Plane. UCS-2 represents a possible maximum of 65,536 characters, or in hexadecimals from 0000h – FFFFh (2 bytes). How does Bandwidth encode its SMS messages? When sending SMS messages, Bandwidth will automatically send messages in the most compact encoding possible.
