A wireless communications system, apparatus and methods provide packet minimized communications between a wireless client and a proxy server. The methods use novel data compression techniques to enable wireless communications devices to complete transactions by exchanging a minimum number of data packets. In many circumstances a transaction comprises a single request packet from the wireless client to the proxy server and a single response packet from the proxy server to the wireless client. The methods use a compact markup language, a compact transport protocol, a reliable message layer, hyperlink indices, server dependent forms, and a compressed user datagram protocol header. A compressed request message comprises a base document uniform resource locator followed by compressed data. The compressed data comprises field values and field indices corresponding to fields in a hyperlink document, and an indication of use of a hyperlink document. A packet of data is formatted so that a compressed user datagram protocol header comprises a first bit set to indicate that the packet destination is a proxy server, bit flags indicating inclusion of optional delivery and internet protocol fields, and a source port number identifying the requesting wireless client.
