Embodiment
Convenient for description of the invention, the core term of substantial grammar SGML CSN.1 is once at first briefly described here:
1, Bit String.The sequence of rules that Bit String is made up of bit, each bit can be got a value in 0 or 1, the string of symbol " bit " expression 1 bit long.
2, empty string.Empty string is that length is 0 Bit String.Represent with symbol " null ".
3, series connection.Series connection is used to express the string of length greater than 1 bit.Its expression mode is the back that simply symbol 0 or 1 is placed on other 0,1 symbols, and the centre can comprise empty string.
4, select.Selection is used to express interchangeable notion.The notion that symbol " | " or " or " expression are selected.The priority of series connection is higher than selection.Change priority and will use brace " { } ".
5, name.The definition of CSN.1 can be named, and name limits with a pair of angle brackets "＜〉".
6, definition.The use symbol ": :=" description string and name of CSN.1 interrelated.After being defined, a name just can in other definition, quote.If quoted oneself in same definition, the recursive definition that this just forms, recurrence are a kind of modes that CSN.1 expresses circulation.
7, Spare bit string.Spare bit is that those appear at the bit that the Bit String end is not used usually, conduct expansion after it can be stayed.
8, filling bit.CSN.1 can L or H replace 0 or 1, CSN.1 has defined one 8 Bit String 00101011 (0x2B) and has been used as the filling use, compared with the bit value of the same position of the bit stream that is formed by unlimited repetition of byte-aligned by this fixing filling string in a certain position of a bit stream, if value is identical is exactly L, and the value difference is exactly H.
9, label.Can use label is that a Bit String distributes a name.Its form is:＜label: the series connection Bit String or quote other definition.
10, index.Be used for representing circulation.It allows to repeat a Bit String by fixed number of times, is expressed as: Bit String (arithmetic expression) or Bit String * arithmetic expression.If use (*) or * * then represent Infinite Cyclic.
After all structures with the message of CSN.1 description, the Bit String of CSN.1 being described in conjunction with grammer has carried out following summary classification in having analyzed 3GPP TS 44.018 and 3GPP TS 44.060 agreements in the present invention:
1, message data field.Such Bit String is described to＜label usually: bit (arithmetic expression)〉form, it has its special implication semantically corresponding to a data field in the message, its semantic interpretation has detailed description in other places of agreement usually.This message data field can be divided into three types according to its semanteme: a kind of is that whole Bit String is treated as a signless integer value, all exist as a number in subsequent analysis processing and in showing, at this moment the length of this Bit String can be above 32.Another kind is that it just is considered as a bit sequence, each bit wherein all has the special implication of oneself, can handle by turn in subsequent analysis processing and in showing, at this moment the length of this Bit String without limits, and to be described to fixed length in agreement sometimes be elongated (being generally elongated) that the time could determine up to concrete decoding sometimes; Also having a kind of is that length only has only 1, and value is the Bit String of L or H, and this value is that L or H have represented different semantemes.Except data field, other Bit String does not belong to message itself, is not saved after decoding is finished, and has only data field to be saved in the specific message structure when decoding, for subsequent analysis processing and demonstration.
2, Spare bit string.Such Bit String is generally used for the end of a bigger Bit String, and it uses predefined symbol＜spare padding usually 〉,＜implicit spare 〉,＜spare bit〉or＜padding bits〉expression.This Bit String is fixed length sometimes, but all is elongated most of the time, and the length that deducts other substrings in the big Bit String by the length with the bigger Bit String that comprises it when its length needs concrete decoding obtains.This Bit String need be skipped, and it is without any physical meaning.
3, control bit string.Such Bit String can be used as the logic flow controlled condition of CSN.1, and CSN.1 is the same with high-level programming language to exist two kinds of logic flows to control: a kind of is exactly that branch is selected; Another kind is exactly circulation, recurrence.The Bit String that is used for this purpose has two kinds of representations: a kind of is 0, the 1 constant Bit String of forming of series connection, the fixed bit string as " 0 ", " 1 ", " 1011 "; Another kind is filling bit L or H.The control bit string that is used for branch's alternative condition can appear at the front or the back of selection operator, and the control bit string that is used for loop control will appear at the front of circulation or recursive description or the condition that the back begins and finishes as circulation.Also have a kind of control bit string as the preamble synchronization string, it is positioned at another Bit String front, identifies the beginning of specific Bit String, and leading string is a constant Bit String normally.
4, VB vacancy bit string.Such Bit String use usually symbol " null " or＜no string, this situation does not need to handle.
