Method for Routing Outgoing and Incoming Data in an NFC Chipset
First Claim
1. A method for routing data in a chipset comprising at least one host processor and an RFID-type contactless data send/receive interface, the method comprising:
- in response to a command for opening a data path sent by a source point located in the host processor and designating a destination point located in the contactless data send/receive interface, defining a data path linking the source point to the destination point by allocating to the data path a routing channel number and by saving in a routing table the routing channel number and routing parameters comprising at least one identifier of the source point and one identifier of the destination point;
sending to the destination point data supplied by the source point by encapsulating the data in a frame having a header field comprising the routing channel number; and
upon receiving data encapsulated in a frame having a header field comprising the routing channel number, searching for a destination point of the data in the routing table by using the routing channel number as an index to select the destination point.

Abstract
A method for routing data in a chipset comprising at least one host processor and an RFID-type contactless data send/receive interface includes, in response to a command for opening a data path sent by a source point located in the host processor and designating a destination point located in the contactless data send/receive interface, defining a data path linking the source point to the destination point by allocating to the data path a routing channel number and by saving in a routing table the routing channel number and routing parameters comprising at least one identifier of the source point and one identifier of the destination point, and sending to the destination point data supplied by the source point by encapsulating the data in a frame having a header field comprising the routing channel number.

12. A device for sending/receiving data comprising an RFID-type contactless data send/receive interface, a controller, and at least one input/output port to link the contactless data send/receive interface to a host processor, the controller being configured to:
-
in response to a command for opening a data path sent by a source point located in a host processor and designating a destination point located in the contactless data send/receive interface, open a data path between the source point and a destination point by allocating to the data path a routing channel number and by saving in a routing table the routing channel number and routing parameters comprising at least one identifier of the source point and one identifier of the destination point; and upon receiving data encapsulated in a frame having a header field comprising the routing channel number, search for a destination point of the data in the routing table using the routing channel number as index to select the destination point. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
