Abstract: A wireless communications system is depicted in which a message can be delivered to a wireless device. In the communications system, a first number included within a true address for communication with the device is associated with the device. A second number distinct from the first number is also associated with the device. A communication is received that includes a phantom address, at least a portion of which includes the second number, and a message. The true address is derived by at least deriving the first number from the second number. The message can then be delivered to the device based upon the derived true address.

Abstract: A system for providing numeric-only paging service to wireless telephone service are shown to include a voice mail system configured to receive dual-tone, multi-frequency signals and convert those signals into a short message service text message. The voice mail system is linked with a short message service server to transmit the short message service text message to the server. In response to receipt of the text message, the server transmits a page to a mobile telephone switching office for ultimate transmission of the text message to a wireless telephone owned by a wireless telephone subscriber. An auxiliary telephone number, distinct from the wireless telephone main telephone number, is assigned for the numeric-only paging service to maintain the privacy of the main telephone number, which translates into reduced airtime.
