Methods to enable efficient use of multiple radio access technologies
First Claim
1. A client node for managing concurrent transmission of data, comprising:
- a first radio configured to use a first Radio Access Technology (RAT);
a second radio configured to use a second RAT;
an Inter-RAT Supervisory Layer (IRSL);
a first protocol stack corresponding to the first RAT;
a second protocol stack corresponding to the second RAT, wherein the first RAT and the second RAT are different; and
a processor coupled to the first radio and the second radio and configured to execute instructions to instantiate the IRSL that spans across the first and second protocol stacks, wherein the instantiation of the IRSL causes the processor to;
initiate transmission, by the first radio, of a first set of data using the first protocol stack, wherein a first portion of the first set of data is associated with a first priority level, and a second portion of the first set of data is associated with a second priority level; and
initiate transmission, by the second radio, of a second set of data using the second protocol stack, wherein the second set of data comprises the second portion of the first set of data, wherein the IRSL duplicates the second portion of the first set of data to form the second set of data according to the second priority level.

Abstract
A device and method are provided for concurrently using a plurality of radio access technologies (RATs) to support a wireless-enabled communications session. A set of data is processed at a client node to identify a subset of priority data. The set of data and the subset of priority data are respectively provided to a first and second protocol stack, which correspond to a first and second RAT. The first and second protocol stacks are then used to control the transmission of a first and second set of transmitted data, which in turn respectively comprise the set of data and the subset of priority data. The first and second sets of transmitted data are received by an access node, which uses corresponding first and second protocol stacks to control their reception. The first and second sets of transmitted data are then processed to generate a set of received data.

6. A method of managing concurrent transmission of data by a client node, comprising:
-
transmitting, by a first protocol stack of a first Radio Access Technology (RAT) of a first radio, a first set of data, wherein a first portion of the first set of data is associated with a first priority level, and a second portion of the first set of data is associated with a second priority level; and transmitting, by a second protocol stack of a second RAT of a second radio, a second set of data comprising the second portion of the first set of data, wherein an Inter-RAT Supervisory Layer (IRSL) duplicates the second portion of the first set of data to form the second set of data according to the second priority level. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. An access node for managing concurrent transmission of data, comprising:
-
a first radio configured to use a first Radio Access Technology (RAT); a second radio configured to use a second RAT; a first protocol stack corresponding to the first RAT; a second protocol stack corresponding to the second RAT; an Inter-RAT Supervisory Layer (IRSL) configured to interface between a first layer of the first protocol stack and a second layer of the second protocol stack via a Service Access Point of the first protocol stack, wherein the second layer of the second protocol stack is a lower layer than the first layer of the first protocol stack; and a processor coupled to the first radio and the second radio and configured to; receive, via the first radio, a first set of data using the first protocol stack, wherein a first portion of the first set of data is associated with a first priority level, and a second portion of the first set of data is associated with a second priority level; and receive, via the second radio, a second set of data using the second protocol stack, wherein the second set of data comprises the second portion of the first set of data. - View Dependent Claims (14, 15, 16, 17)
