摘要： The embedded information receiver protocol provides an improved method for transmitting and receiving new or updated individual and multi-recipient messages in selective call receivers. The embedded protocol of the present invention is designed to be compatible with both POCSAG and FLEX signaling protocols and further to be implemented without requiring any changes to paging terminal software. Additionally, according to the present invention, a selective call receiver is provided comprising receiving means for receiving radio messages, a display for displaying information including received messages, user operable input means for controlling functions of the receiver, and storage means for storing messages received, the selective call receiver further comprising means for receiving messages transmitted in the embedded protocol. In general, the protocol is comprised of five field types, however all five fields need not be employed for effective use of the protocol. Additionally, six commands are supported by the embedded protocol, however this set is easily extensible such that the protocol can evolve as needed without modifying the basic protocol structure. The embedded protocol of the present invention minimizes transmission overhead in several ways. Specifically, certain of the commands mentioned permit selective transmission or updating of any portion of an existing message such that changes can be made to a message without retransmitting the entire message. Furthermore, the update type transmission can be applied to any type of message, not just database messages. Another advantage of the present invention is that the message structure can be shortened if certain of the field types are not required to interpret the message.
