Abstract
Method and apparatus for transmitting messages in a two-way paging system are disclosed. Reply codes corresponding to portions of a message to be transmitted by a base station and received by a mobile pager device are computed either at the base station or at the pager according to various embodiments. The reply codes, which are typically shorter and require less bandwidth than the full text to which they correspond, are incorporated by the pager into reply messages when the user of the pager device wishes to refer to portions of the text of the received message in his reply. The present invention advantageously allows the user of a pager device to respond to a received message by transmitting a reply message that incorporates part of the text of the original received message without significantly increasing the bandwidth required to transmit the response.
