The target Node-B reconfigures a radio link and reports successful reconfiguration to the DRNC(623). The DRNC delivers information on the USTS mode radio link to the SRNC(624). The SRNC commands an SRNS(Serving Radio Network Subsystem) Node-B to reconfigure a radio link to a non-USTS mode(625). The SRNS-Node-B reconfigures a radio link and reports successful reconfiguration to the SRNC(626). The SRNC commands the DRNC to activate the USTS mode radio link(627). The DRNC commands the target Node-B to activate the USTS mode radio link(628). The SRNC commands the SRNS-Node-B to activate the non-USTS mode radio link(629).
