Abstract

Techniques are disclosed for generating a message stream configured to indicate a source of the various messages within the message stream. In particular, the indicators identify which interface the messages were received at a terminal (e.g., of a mobile handset). The terminal receives messages on various interfaces, and separates the messages received via different interfaces with interface switch indicators within the message stream. In one embodiment, the smart card receives a message stream that includes sets of messages and interface switch indicators therein. The smart card delivers messages from the message stream to a single logical partition of the smart card up until an interface switch indicator is identified in the message stream. From that point, the smart card delivers messages from the message stream to a different logical partition of the smart card up until another interface switch indicator is identified in the message stream.

Claims21

Dependent claims

One or more non-transitory machine-readable media storing instructions which, when executed by one or more processors, cause:

receiving, at a terminal, a plurality of messages, the receiving operation comprising:
receiving, at the terminal via a first interface, a first subset of the plurality of messages destined for a first logical partition of a smart card;
receiving, at the terminal via a second interface, a second subset of the plurality of messages destined for a second logical partition of the smart card;
generating a message stream comprising the plurality of messages, the generating operation comprising:
ordering the plurality of messages within the message stream in a chronological order based at least in part on a respective time at which each of the plurality of messages are received at the terminal;
and
inserting interface switch indicators corresponding respectively to each switch between (a) messages from the first subset of the plurality of messages, and (b) messages from the second subset of the plurality of messages in the message stream;
and
transmitting, by the terminal to the smart card, the message stream comprising the ordered plurality of messages with the inserted interface switch indicators.
