Longer messages can be split to multiple parts and sent as a Concatenated SMS. In all octets the values are stored in binary coded decimal format with switched digits number 35 is stored as 53 hex. GSM recognizes only 2 encodings for text messages and 1 encoding for binary messages:.

However, the validity period is usually limited globally by the SMSC configuration parameter— often to 48 or 72 hours. This behaviour was designed for older mobile phones which don’t understand UDH; such mobile phones might display the UDH as a jumble of strange characters; if the first character after UDH was Carriage Return CRthe mobile phone would rewrite the mess with the rest of the message.

When the message encoding is GSM 7-bit default alphabet and a UDH is present, fill bits are inserted to align start of the first character of the text after UDH with septet boundary. The value of 1 in the bit 7 of the first octet indicates that TP-VP functionality indicator extends to another octet.

Views Read Edit View history. The alphabet contains the most-often used symbols from most Western-European languages and some Greek uppercase letters. The following 3 octets contain a relative validity period in hours, minutes and seconds as the 3rd to 5th octet of time format.

A special DCS values also allows message compressionbut it perhaps is not used by any operator. The fields of SM-TP messages, including their order and size, are summarized in the following table, where M means a mandatory field, O an optional field, E is used for fields which are mandatory in negative responses RP-ERR and not present in positive responses RP-ACKx is a field present elsewhere:.

The TP-DCS octet has a complex syntax to allow carrying of other information; the most notable are message classes:. If the time zone offset is negative in Western hemisphere bit 3 of the last octet is set to 1.

Message 2040 Indication group of DCS values can set or reset flags of indicating presence of unread voicemailfaxe-mail or other messages. Enhanced format of TP-VP field is seldom used. This page was last edited on 1 Novemberat The content of the message its text when the message is not 32040 binary one is carried in the TP-UD field. In this example, the time zone, 8A is binary The value of 1 in the bit 6 of the first octet means that the message is Single-shot.

Setting the TP-RP bits turns on a feature which allows to send a reply for a message using the same path as the original message. However, the original name is often used to refer even to the 3GPP document. TP-PID Protocol identifier either refers to the higher layer protocol being used, indicates interworking with a certain type of telematic device like faxtelexpagerteletexe-mailspecifies replace type of the message or allows download of configuration parameters to the SIM card. Alphanumeric address is at first put to the GSM 7-bit default alphabet, then encoded the same way as any message text in TP-UD field that means it is 7-bit packed and then the address is supplied with the “number” length and TON and NPI.

Other addresses are carried by lower layers. Although these changes are ancient version 6.

The non-segmented message using national language shift table s may carry up to or 7-bit characters. By using this site, you agree to the Terms of Use and Privacy Policy. Retrieved from ” https: Flash messages are received 233040 a mobile phone even though it has full memory.

These characters form GSM 3ggpp default alphabet extension table. Its 3 least significant bits have the following meaning:. The remaining number bit-wise ‘and’ with ishexadecimal Bit 3 is 1, therefore the time zone is negative.

The MSC usually does not close the connection to the mobile phone and does not end the MAP dialogue with the SMSC, which allows faster delivery of subsequent messages or message segments. This format is used throughout the whole transfer of the message in the GSM mobile network. In this case the number must adhere to the mobile operator’s dial planwhich means that international numbers must have the international prefix 00 in most countries, but in the USA before the country code and numbers for long-distance calls must start with the trunk prefix 0 in most countries, 1 in the USA followed by a trunk code.

Languages which use Latin scriptbut use characters which are not present in the GSM 7-bit default alphabet, often replace missing characters with diacritic marks with corresponding characters without diacritics, which causes not entirely satisfactory user experience, but is often accepted.

However, a GSM The absolute format is identical to the other time formats in GSM The same was also true for other languages using non-Latin scripts like Russian, Arabic, Hebrew and various Indian languages. From Wikipedia, the free encyclopedia. Such message may be sent only if the original message had this flag cleared and the new message must be sent with the flag set. For example, a fictional alphanumeric address Design Home is converted to the GSM 7-bit default alphabet which yields 11 bytes 44 65 73 69 67 6E 00 48 6F 6D 65 hex 3gp, the 7-bit packing transforms it to 77 bits stored in 10 octets as C4 F2 3C 7D 76 03 90 EF 76 19; 77 bits is 20 nibbles 14 hex which is the value of the first octet of the address.

Messages sent via this encoding can be encoded in the default GSM 7- bit alphabet, the 8-bit data alphabet, and the bit UCS-2 alphabet. The number itself must always start with a 223040 code and must be formatted exactly according to the E.

Treat this as any previous element in the sequence, hex 82 represents number The following octet is a relative validity period as described in the Relative Validity Period Values table.

They are not stored 3bpp the phone, they just displayed on the phone display. It has always 7 octets, although some of them are not used. If the originator and the recipient home networks differ, the reply would go through another SMSC then usually.
