Hi all, I need to confirm something in regards to the SMPP protocol v3.4.
I'm interested in the submit_sm pdu, its data_coding field and short_message data. According to the SMPP developers forum 'Short Messsage Peer to Peer Protocol Specification v3.4 document' ... sections 5.2.19 data_coding (p. 126) and 5.2.22 short_message (p. 128) ... A data_coding value of 0x00 means message centre default alphabet, thus MC / provider specific. However, usually this tends to be the GSM 03.40 7 bit alphabet. However, since the SMPP submit_pdu's short_message field is up to 254 *Octets* then, if the alphabet coding is GSM 7 bit, should not the Bytes in the short_message Octet buffer be converted to septets before sending? I've found that of the providers / MCs that we use, they accept GSM 7 bit characters encapsulated in 8 bit Octets. Is this correct behaviour? Or are we all doing it wrong (including kannel)?... maybe we should be packing the Bytes into septets? Anybody on the SMPP developers forum on this list? Anyway... Later. -- Benjamin Lee Level 2 71-75 City Rd, South Melbourne, VIC 3006 Australia Phone +61 3 8699 1333 Mobile +61 414 717 573 Fax +61 3 8699 1388
