Abstract

Parameters are defined for use on an interface (lub/lur) between network elements to enable configuration setup of an enhanced radio uplink (UL E-DCH). The basic Information Elements (IEs) are defined to support UL E-DCH functionality in the network on lub/lur. Particular parameters are shown for communication over the lub/lur interface between the RNCs and the Node Bs in order to be able to setup and re-configure the UL E-DCH channel. Flexibility is provided so as not to be restricted to any particular message or information element, but to be applicable to any selected message or messages in a given protocol.
