An overview of common packet channel (CPCH), an optimum wireless Internet mechanism in 3GPP W-CDMA system and comparison of various UMTS non real time data deployment options

摘要

With the rise of interest in wireless Internet and wireless packet data communications on one hand and explosion of interest in IP and packet-switched based networks on the other, it is beneficial to bring the packet switching capability to the air interface which is the last hop in network. The common packet channel (CPCH) has been included in the third generation wideband direct sequence code-division multiple access (3G W-CDMA) technical specifications to meet this growing demand and need in an efficient manner. This paper will address the CPCH benefits, applications, CPCH access method and comparison of various UMTS base node deployment scenarios.
