Detailed Comments

For GSM dedicated physical channel, the ciphering mode of the SS shall be changed in three steps: (3GPP TS 44.018 [43], clause 3.4.7)

Before the SS sending CIPHERING MODE COMMAND the SS is transmitting and receiving in old ciphering mode (for example, not ciphered), after the SS sending CIPHERING MODE COMMAND the SS changes its receiving ciphering mode to new ciphering mode (for example, ciphered) and keeps transmitting in old ciphering mode; then after receiving CIPHERING MODE COMPLETE or any correct L2 frame in new ciphering mode the SS changes the transmitting ciphering mode to the new mode.

TTCN writer shall use this ASP before sending the CIPHERING MODE COMMAND to ensure the ciphering mode of the physical channel, in sufficient time, according to the 3 step procedure outlined above.

Detailed Comments

This ASP is used to assign, change, or unassign the TLLI, the ciphering key (Kc) and the ciphering algorithm.

1. The oldTLLI and newTLLI parameters shall be interpreted as follows:

– If oldTLLI = all 1’s and newTLLI  all 1’s then newTLLI is assigned and used when (re‑)transmitting LLC frames. If an oldTLLI  all 1’s was assigned to the LLME, then oldTLLI is unassigned. Only newTLLI is accepted when received from the peer. It shall be treated as a TLLI change. If oldTLLI = all 1’s was assigned to the LLME, then this shall be treated as a TLLI assignment, and this ASP shall be the first ASP sent to the SS in order to enable LLC to process requests from layer 3.

– If oldTLLI  all 1’s and newTLLI  all 1’s then oldTLLI and newTLLI are assigned, and newTLLI shall be used when (re‑)transmitting LLC frames. Both oldTLLI and newTLLI shall be accepted when received from the peer. It shall be treated as a TLLI change.

– If oldTLLI  all 1’s and newTLLI = all 1’s then oldTLLI shall be unassigned. It shall be treated as a TLLI unassignment, and this ASP shall be the last ASP sent to the SS in order to disable LLC to not process requests from layer 3 any longer.

2. Kc and Ciphering Algorithm are associated with newTLLI (and with oldTLLI if assigned):

– If Ciphering Algorithm indicates no ciphering, then the ciphering function shall be disabled.

– Otherwise, the ciphering function shall be enabled. If a Ciphering Algorithm was already associated with newTLLI or oldTLLI, then the new Kc shall replace the previous Kc, and Ciphering Algorithm shall replace the previous algorithm selection. All I frames, and UI frames with the E bit set to 1, shall use the new Kc and algorithm for ciphering. All unacknowledged I frames shall be ciphered using the new Kc and algorithm before retransmission. As an implementation option, the previous Kc and algorithm may be used to decipher received frames.

NOTE 1: The value of cipherAlgorithm dictates which of cipherKey or cipherKey128 shall be used by the SS.
