Instructions

This decoder decodes messages specified in the 3GPP TS 24.008 V10.15.0 (2014-09) [download spec], Mobile radio interface Layer 3 specification - Core network protocols; Stage 3 specification.

The messages are divided among the following message sets. The right message set must be selected before submitting the binary data to be decoded.

Downlink

These messages are sent from the network to the mobile station. They are identified by a 4 bit protocol discriminator and 8 bit message type.

This link decodes a sample AUTHENTICATION REJECT message (TS 24.008, 9.2.1).

Uplink

These messages are sent from the mobile station to the network. They are identified by a 4 bit protocol discriminator and 8 bit message type.

This link decodes a sample AUTHENTICATION FAILURE message (TS 24.008, 9.2.3a).

Downlink (with extended transaction ID)

These messages are sent from the network to the mobile station for GPRS management. They are identified by a 4 bit protocol discriminator and 8 bit message type.

This link decodes a sample ACTIVATE PDP CONTEXT REJECT message (TS 24.008, 9.5.3)

Uplink (with extended transaction ID)

These messages are sent from the mobile station to the network for GPRS management. They are identified by a 4 bit protocol discriminator and 8 bit message type.

This link decodes a sample REQUEST PDP CONTEXT ACTIVATION REJECT message (TS 24.008, 9.5.8).

Binary input field

The binary input field supports the following format:

0/1Numbers 0 and 1 are inserted as bits. So 1100 is encoded as four bits 1, 1, 0 and 0.
dNwhere N is a decimal value in range 0..255; it is encoded as an 8 bit value. For example, d240 will be encoded as 11110000.
xNwhere N is an hex value in range 0..FF; it is encoded as an 8 bit value. For example, xF0 will be encoded as 11110000.
d{K}N / x{K}NSame as dN/xN but encoded in K bits. For example, d{3}2 will be encoded as 010.
