Abstract

The present invention provides a method and apparatus for creating a packet having one or more compressed headers. Call set-up information is received. Thereafter, call data is received and a data portion of the packet is created using the call data. One or more current headers are created using the call data and the call set-up information. The one or more current headers are compressed. The packet is then created by attaching the one or more compressed headers to the data portion of the packet. The one or more compressed headers are created using one or more differences between the one or more current headers and the one or more previous headers. After compression, the one or more current headers are saved as the one or more previous headers.

Description

technical field [0001] The present invention relates generally to the field of communications, and more particularly to methods and devices for compressing packet headers. Background technique [0002] The ever-increasing need for data communications has prompted the development of technologies that provide cheaper and more efficient methods of using communications networks to process more and new types of information. One such technique is to segment the information, which may be voice or data communication, into packets. A packet is usually a set of binary digits, including at least data and control information. An integrated packet network (typically a fast packet network) is usually used to carry at least two services, which may include, for example, continuous bit rate ("CBR"), voice ("packet voice"), data ("framed data"), video, and many more. A packet network source receives and / or forwards protocol packets. Each packet has a defined format and includes one or mor...
