CS domain and PS domain

CS domain and PS domain - домен криптографической системы и домен коммутатора пакетов?? (это то как я смог перевести)

Контекст:
Some differences to be noticed between 2G & 3G systems and as far as the network are concerned:
· in 2G systems: ciphering is performed in the BTS (for the CS domain) or in the SGSN (for the PS domain);
· in 3G systems: ciphering is performed in the RNC (for the CS domain and for the PS domain).

Заранее спасибо

имхо, PS domain - домен с коммутацией пакетов, CS domain - домен с коммутацией каналов.
