Message Waiting Indication group of DCS values can set or reset flags of indicating presence of unread voicemailfaxe-mail or other messages. 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.

Any handset must be able to receive such short message irrespective of whether there is memory available in the U SIM or ME or not, must acknowledge receipt of the message, but must not indicate its receipt to the user and must discard its contents, so the message will not be stored in the U SIM or ME.

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. However, no such extensions are defined. 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.

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.

Bit 3 is 1, therefore the time zone is negative. The TP-DCS octet has a complex 230040 to allow carrying of other information; the most notable are message classes:. GSM recognizes only 2 encodings for text messages and 1 encoding for binary messages:.

In this example, the time zone, 8A is binary The g3pp of 1 in the bit 6 of the first octet means that the message is Single-shot. In all octets the values are stored in binary coded decimal format with switched digits number 35 is stored as 53 hex.

However, a GSM Enhanced format of TP-VP field is seldom used. The alphabet contains the most-often used symbols from most Western-European languages and some Greek uppercase letters.

Longer messages can be split to multiple parts and sent as a Concatenated SMS. If the originator and the recipient home networks differ, the reply would go through another SMSC then usually. 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.

Treat this as any previous element in the sequence, hex 82 represents number They are not stored in the phone, they just displayed on the phone display. 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 hexthe 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. Retrieved from ” https: 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.

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 value of 1 in the bit 7 of the first octet indicates that TP-VP functionality indicator extends to another octet. However, the validity period is usually limited globally by the SMSC configuration parameter— often to 48 or 72 hours. This format is used throughout the whole transfer of the message in the GSM mobile network. 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.

Other addresses are carried by lower layers.

The mobile operator must take special measures to charge such messages. Views Read Edit View history. The following octet is a relative validity period as described in the Relative Validity Period Values table. It has always 7 octets, although some of them are not used.

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 content of the message its text when the message is not a binary one is carried in the TP-UD field.

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. The remaining number bit-wise ‘and’ with ishexadecimal This page was last edited on 1 Novemberat From Wikipedia, the free encyclopedia.

A special DCS values also allows message compressionbut it perhaps is not used by any operator. 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.

Flash messages are received by a mobile phone even though it has full memory. These characters form GSM 7-bit default alphabet extension table. The following 3 octets contain a relative validity period in hours, minutes and seconds as the 3rd 33gpp 5th octet of time format.
