or we are developing our own tool? how is it? Please explain with some examples.
If you want to decode any encoded message (Amy be RRC / S1 AP/ X2AP) then u can use the web tools available by third party freely.They will give you the values you filled in the asn structure in XML Format. Try it !!! It's very good and helpful
If you have encoded Buffer then u can use this tool by giving buffer content http://www.obj-sys.com/asn2xml.php http://www.marben-products.com/asn.1/services/decoder-asn1-lte.html
If you have encoded file then u can use http://asn1-playground.oss.com/
I dont know your real requirement, but check this http://www.marben-products.com/asn.1/services/decoder-asn1.html it can decode packet based on the interface. You can play a bit.
If you are looking for the ASN compiler, then please check asn1c at http://sourceforge.net/projects/asn1c/ . I hope it helps.
Please share why and how ASN Encoder/Decoder are used in telecom (protocols)?
interprocess is a communication mechanism like ipc as per my knowledge. so in 3GPP also any interprocess is available or not?
