Abstract: Provided is a method for dynamically selecting a mobile subscription for a secure element cooperating with a terminal in a telecommunication system comprising a network visited by the terminal and a HSS of a server The method includes sending from the secure element a random e-IMSI ephemeral IMSI in a first attachment request message to the HSS through the visited network, the visited network having the best received signal and having a roaming agreement with an e-IMSI service provider; and transmitting 101 from the HSS to the secure element in a signaling message a PLMN list of all the local operators having a commercial agreement with the e-IMSI service provider.

Abstract: A method to attach a mobile device to a server, using a protocol having data size encoding constraints which prevents using traditional ciphering, includes an initialization phase using a range of ephemeral IMSIs stored in a batch of credential containers of mobile devices and an associated group master key shared by the server and credential containers having the same range of ephemeral IMSIs to initiate a session using a server random value. The initialization phase uses limited payload in a mobile device-to-server message to send a randomly chosen rIMSI among the range of IMSIs to enable the server to generate keys to initiate a secured communication phase, then using individual keys stored in the mobile device and retrieved by the server with an identifier of the credential container sent in a mobile device-to-server message and with an individualization master key owned by the server.

Abstract: Systems, methods, and computer program products for an On-Line Transaction Processing (OLTP) system. Payment and merchant information is stored in a database record for each product in a set of products from multiple suppliers. In response to receiving a request to refund products in the set, the OLTP system may determine the merchant, a number of payments, and the amount of each payment for each product being refunded based on the payment and merchant information in the database record, and trigger payments between the supplier, seller, and buyer. In response to detecting an error, the OLTP system may store a status of the refund processing in the database record and queue the transaction for processing by a call center. In response to receiving a restart request, the OLTP system may retrieve the status data from the database record and restart processing of the refund based on the status data.
