Service Anti-Collision Method for Host Controller Interface Equipment Booting Method and Host Controller therefor

摘要

A method for preventing a service conflict in a terminal device including a UICC (Universal Integrated Circuit Card) host and a host controller supporting various RF technologies, and a terminal device and a host controller therefor, RF parameter (SELECTED_AID_RF) from the host controller management gate when one of the card RF gates receives a service application select (SELECT) signal from the outside, It is possible to prevent the collision of the service application by determining whether the service application specified by the service application select (SELECT) signal is executable using the selected service / RF parameter (SELECTED_AID_RF).
