The USSD is a very popular and simple way to reach services in all mobile network generation. The telecom protocols based in IP (SIGTRAN) are used to integrate the USSD server to the mobile network. With the 4G and 5G networks the IP Multimedia Subsystem (IMS) is deployed for the services integration. The SIP is used by default to transport the signaling information in the IMS core. There is a big different between using SIGTRAN and SIP to transport the USSD messages. The goal of this paper is to analyze the resources usage and the more optimize protocol to transport the USSD messages. The results are obtained by using the USSD server with UTRAN radio access and the USSI with eNodeB/gNodeB in Non-Stand-Alone configuration.
