What do you mean by "message center" ? Do you mean MSC (mobile service
switching centre)? Encryption/decryption in GSM is done in between MS
(mobile station) and BS (base station). Keys are stored in SIM and AuC
(authentication center).

Anyway, can you point some vendors that provide hardware that supports A5/3 ?

Its not about base stations. The encryption/decryption is not done in
base stations, but in message centers. Sometimes, true, they are located
in same spot. But they are still not the same thing, but two different
components of the GSM network.
