ABSTRACT:
Messages are pushed to handsets using a secondary carrier channel separate from the wireless network. The handset includes a secondary carrier receiver, which may share a power source and other components with the wireless network receiving hardware included in the handset. When the handset receives a message broadcast over the secondary carrier channel or one of multiple secondary carrier channels, the message is then stored in a message memory of the handset. A stored message is output from the message memory in a user understandable format, e.g., audibly or visually, through the handset hardware in response to a predetermined operation of the handset. A stored message may be output in response to a “send” operation of the handset, prior to the establishment of a communication link between the handset and a base station of the wireless network. In the case where message output occurs in response to a “send”, the user will be listening for the call to be connected and an excellent opportunity is presented for a short advertising message. The preferred secondary channel is the commercial AM or FM radio sub-carrier channel. The handsets and method for message delivery provide for a novel method to promote an entity, which can subsidize the cost of handsets for distribution to targeted persons. The handsets then receive messaging that promotes the entity for a period.
