Multimedia calls addressed an increased data rate are disclosed. The multimedia calls use the multicall supplementary service in circuit switched mobile networks and a multilink operation to separate calls for each portion of the total session. The calling entity establishes several calls to the same party. The sending entity splits the data into the separate simultaneous channels/calls. The receiving entity combines the data received from the separate simultaneous calls (multicall, multilink). IP-based multimedia uses one session for each media component. The IP/CS interworking is arranged, if the CS leg uses a multicall/multilink operation.

A payment system implemented on a mobile device authorizes and processes transactions. The mobile device generates a public-private key pair and receives payment information. The private key and the payment information are split into a local and a remote fragment. The public key, a private key fragment, and a payment information fragment are sent to a secure payment system, and the other fragments are stored on the mobile device. When a transaction is received by the mobile device to authorize, the mobile device sends a payment fragment to the secure payment system and receives a private key fragment from the secure payment system. The mobile device authorizes the transaction using the private key, recovered from the private key fragments. The secure payment system verifies the transaction using the public key and processes the transaction using the recovered payment information. Additional techniques to process transactions using data splitting are disclosed.
