ABSTRACT:
Preventing unauthorized monitoring of wireless data transmissions is accomplished by routing requests for data, from communication units (114) operating on wireless communication systems (101), to a security gateway (103) which determines a transmission security level, based on the type of data requested, the identity of the data requester, and the identity of the database containing the requested data. Once this is determined, the security gateway (103) establishes a secure communication with the communication unit according to the transmission security level. If the secure communication was successful, the security gateway (103) routes the requested data to the communication unit (114).
