However, it has been found in practice that during the initialization process of the eUICC, there may be no communication applications, that is, there is no activated subscription information set for accessing the operator's network in the eUICC. At this time, the modem in the terminal device The modem will consider the eUICC as an invalid card and terminate the session with the eUICC

Abstract

An application processing method and device for an embedded universal integrated circuit card, wherein the method includes: a terminal device activates an embedded universal integrated circuit card eUICC (201); during the initialization process of the eUICC, the terminal device selects the eUICC The root security domain ISD-R in the eUICC is applied to maintain the session between the terminal device and the eUICC (202). The method can keep the session between the terminal equipment and the embedded universal integrated circuit card during the initialization process of the embedded universal integrated circuit card.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an application processing method and device for an embedded universal integrated circuit card. Background technique [0002] Embedded Universal Integrated Circuit Card (eUICC) is a Universal Integrated Circuit Card (UICC) embedded in a terminal device. The main difference between UICC and eUICC is: UICC is written for The signing information set for accessing the operator's network. The signing information set in the UICC cannot be changed after leaving the factory. However, the eUICC may not be written in the signing information set for accessing any operator's network during production. Choose to sign with an operator and write the downloaded subscription information set of the operator's network into the eUICC. Among them, both the UICC and the eUICC can include various communication applications, such as: Subscriber Identity Module (Subscriber Identity Module, SIM) ap...
