982 | |
983 In case of components concatenated with a CSN1 coding | |

986 types (like tagged types, e.g. GSM3_TV) characterise | |
987 optional elements inherently. The value of their valid | |
988 flag indicates the presence or absence of such an element. | |
989 Components concatenated with a CSN1 coding type cause | |
990 these valid flags in the C header structure too. If you | |
991 find a bit in the received message stream indicating | |
992 optional values not included in the message (e. g. a | |
993 CSN1_S1 element is represented by ??, CCD will set the | |
994 valid flag to zero. But the whole element represented by | |
995 the flag is present; only the value is absent! Therefor | |
996 the valid flag in the C structure is not an indication of | |
997 an element’s absence. | |

1519 PURPOSE : codes the content of a C-Structure into a bitstream. | |
1520 This function may be called recursivly if an IE in the | |
1521 structure is itself a structured IE. | |
1522 | |
1523 For extended octet groups the following rules apply. | |
1524 | |
1525 Any IE within an extension octet is characterised by its | |
1526 extGroup which is one of the following: | |
1527 | |
1528 | |
1529 '+' octet begins with this IE. | |
1530 ' ' octet continues with this IE or a new octet begins. | |
1531 '-' octet ends with this IE. | |
1532 '*' octet group ends with this IE. | |
1533 | |
1534 An octet may begin with '+', '-', ' ' or '*'. | |
1535 An octet beginning with '-' or '*' is made of only one IE (7 bits). | |
1536 A group made of one octet has only one IE with '*'. | |
1537 If '+' is present, next IEs ending with '*' or '-' are present too. | |
1538 If the beginning IE with ' ' is not IE | |
1539 | |

1562 | |
1563 The status of encoding is given as follows: | |
1564 | |
1565 ExtendedGroupActive is set to 1 if '+' is present in the encoding. | |
1566 ExtendedGroupActive is changed from 1 to 0 when encoding '*'. | |
1567 ExtendedGroupActive is set to 0 if an octet beginning with ' ' is | |
1568 not present. | |
1569 OpenNewOctet is set to 1 after encoding an IE with '-'. | |
1570 ExtBitPos1 is set to the globs->bitpos when writing extension bit: | |
1571 1) for '+' or | |
1572 2) for ' ' after '-' | |
1573 | |
1574 Extension bit is set to 0 if a further octet is encoded for | |
1575 the group. If an octet is the last one within a group, the | |
1576 extension bit is set to 1. | |
1577 | |
1578 While processing the first IE of an octet (e.g. for '+'), | |
1579 if the IE is absent, CCD will skip over all IEs up to the | |
1580 ending '*'. | |
1581 When processing IEs with ' ' and for ExtendedGroupActive=1 the valid | |
1582 flag is set to 1 in order to compensate probable mistakes in PS. | |

2277 "Bit 8 of the IEI octet is set to "1" indicates a TV | |
2278 formatted type 1 standard IE or a T formatted type 2 | |
2279 IEs, and to "0" indicates a TLV formatted type 4 IE. | |
2280 Hence, a 1 valued bit 8 indicates that the whole IE is | |
2281 one octet long, and a 0 valued bit 8 indicates that the | |
2282 following octet is a length octet. | |
2283 1) Rules to read the length: | |
2284 For TLV4 encode L in one byte. | |
2285 For TLV5 and ASN.1 encode in one byte or more. Use | |
2286 0x81, 0x82 etc in the first byte to say L is encoded | |
2287 in one, two etc bytes. | |
2288 For ASN.1 BER type use 0x80 in the first byte and | |
2289 two otets of 0 bits after the encoded IE. | |
2290 For all the three types it is possible to encode L | |
2291 in only one byte. | |
