A Design and Implementation of ASN.1 Parser for H.323 Protocol Stack

Design and application of the ASN.1 module in the LTE-Uu interface protocol stack

“…Be noted that, the encoding of the ASN.l data types must be done strictly in accordance with X.691 protocol in the specific implementation. Even if it is a bit of error, the L TE system may not work correctly [31. Literature [4][5][6][7] discussed the approach about the proposed development through the automated ASN.l compiler and new runtime, etc, but these are mainly for the TD-SCDMA and other protocol standards, and on the one hand , Some features of LTE-Uu interface protocol stack has made great changes in comparison with the TD-SCDMA. On the other hand, signaling messages with the L TE protocol version change is still constantly changing.…”

“…On the other hand, signaling messages with the L TE protocol version change is still constantly changing. Therefore, this paper get the advantages of their ASN.l module in [4][5][6][7], on the encoding and decoding technology of the signaling messages in LTE-Uu interface protocol stack ,which described in the ASN.1 language , and based on this test application process simulation do exploratory research.…”
