摘要： A method (300) for performing encrypted communication in a wireless communication system having a centralised network operably coupled to a serving communication unit that wirelessly communicates with a plurality of remote communication units. The method comprises the steps of transmitting an encrypted message, preferably a registration message, from one of the plurality of remote communication units to the serving communication unit where the serving communication unit does not contain a key to decrypt the encrypted message. The serving communication unit (122) stores (335) the encrypted message and retrieves (330) a key from the centralised network to facilitate decryption of the encrypted message. A communication system and associated communication units are also described.
In storing encrypted messages such as registration messages, coupled with a key retrieval mechanism, mobile subscriber units are able to perform encrypted registration without either the subscriber unit or the system knowing where or when the encrypted registration request will be made.
