The invention relates to a method for an improved installation of a secure-element-related service application in a secure element being located in a communication device, wherein the secure-element-related service application, installed within the secure element, allows a first server entity of a service provider, together with a UE-related application installed on the communication device, to provide a service to the subscriber of the telecommunications network, wherein a secure element issuer corresponds to the secure element, wherein the method comprises the following steps:
-- in a first step, an initial request is transmitted by the UE-related service application of the communication device towards the first server entity to request installation of the secure-element-related service application in the secure element, the initial request being transmitted by means of a request message,
-- in a second step, subsequent to the first step, the request to install the secure-element-related service application is transmitted, by the first server entity, to the second server entity, the second server entity generating the token information related to the request to install the secure-element-related service application in the secure element of the communication device, and the second server entity transmitting the token information to the first server entity related to the request to install the secure-element-related service application in the secure element,
-- in a third step, subsequent to the second step, a token information is transmitted, by the first server entity to the UE-related service application of the communication device,
-- in a fourth step, subsequent to the third step, an access and/or installation request, related to the secure-element-related service application, is transmitted, together with the token information, by the UE-related service application of the communication device to a proxy application of the secure element issuer, the proxy application being able to access the secure element and/or to install secure-element-related applications on the secure element, wherein the proxy application is able to interact with the secure element of the communication device and is installed in the communication device as a link between, on the one hand, a second server entity of the secure element issuer, and, on the other hand, the secure element of the communication device, the second server entity being a server entity related to the secure element issuer,
-- in a fifth step, subsequent to the fourth step, a communication link is established between the proxy application and the second server entity such that the token information, together with a SEID information (Secure Element Identifier information) of the communication device is transmitted to the second server entity in order to be validated by the second server entity. |
