Instructions
This decoder decodes messages specified in the 3GPP TS 24.008 V15.6.0 (2019-03) [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:
| 0/1 | Numbers 0 and 1 are inserted as bits. So 1100 is encoded as four bits 1, 1, 0 and 0. |
| dN | where 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. |
| xN | where 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}N | Same as dN/xN but encoded in K bits. For example, d{3}2 will be encoded as 010. |
