A method is disclosed that includes sending () a first full header from a source compressor () to a destination decompressor () wherein the source compressor and the destination decompressor are a part of a symmetrical configuration. An IP packet including the full header is compressed into a first compressed header () based on the context established in the first full header. The first compressed header is sent () from the source compressor to the destination decompressor. The compressor receives () a second full header from the destination compressor wherein the second full header indicates that the destination decompressor did not receive the first full header. The second full header can include a modified field or has an incremented generation identification. The source compressor sends () another full header to the destination decompressor.

A system and method for enabling scheduled data messages to be transmitted within a communication system on a controlled access packet data channel. When a scheduled data message is to be transmitted, a mobile device generates the data message, appends a predetermined type of header to the data message, and passes the data message to a communication unit. The header comprises an hour field, a minute field, and a slot field indicative of a specific time when the data message is to be transmitted on the controlled access packet data channel. After receiving a data message from the mobile device, the communication unit parses the received data message to determine whether the received data message should be processed as a scheduled data message on the controlled access packet data channel, and transmits the data message to a fixed network at a specific time based on the hour, minute, and slot fields in the header.

A method and apparatus for maintaining communications between a mobile computer and a mobile subscriber unit is disclosed. The method and apparatus comprise determining whether a connection is available between the mobile subscriber unit and a radio communications system. If a connection is available, then the method and apparatus include retrieving a first IP address for the mobile computer from the radio communications system. Then, the method and apparatus comprise caching the first IP address in the mobile subscriber unit for use by the mobile computer. Finally, the method and apparatus include utilizing the first IP address even if the radio communications system is unavailable and updating the first IP address with a second IP address obtained from the radio communications system when the radio communications system is available.
