Abstract

A method and system for managing M2M traffic in a network is provided. The M2M device sends a message that includes a machine identity for the M2M device. A query is submitted to a database that correlates the machine identity with a QoS parameter or a priority. The message is assigned to one of a plurality of input queues based on the assigned QoS parameter or priority. Each input queue is associated with a delay period so that the message is held in the queue for a period less than the delay period.

Claims

1. A method comprising:

receiving in a radio network a request to transmit a message from a first device through a cellular network to a second device, the request including a machine identity for the first device and not including any QoS parameters;

submitting a query to a database in a core network that correlates the machine identity with an associated QoS parameter;

determining the associated QoS parameter associated with the first device based on the machine identity;

assigning an assigned priority to the message, the assigned priority selected from at least a first priority and a second lower priority based on the associated QoS parameter; and

assigning the message to an assigned input queue in the radio network based on the assigned priority, the assigned input queue selected from among a first input queue having a first associated delay into which a set of first priority messages are assigned and a second input queue having a second associated delay into which a set of second priority messages are assigned.

2. The method of claim 1 wherein the associated QoS parameter is latency.

3. The method of claim 2 wherein the first associated delay is shorter than the second associated delay.

4. The method of claim 1 further comprising holding the message in the assigned input queue until all messages of higher priority have been transmitted.

5. The method of claim 4 wherein first priority messages have low latency and second priority messages have higher latency.

6. The method of claim 1 wherein the first input queue and the second input queue are located in a eNode B access point.

7. A system comprising:

a radio network;

a core network connected to the radio network;

a node in a radio network that receives a request to transmit a message from a first device, the request including a machine identity for the first device and not including any QoS parameters;

a subsystem that determines the machine identity for the first device;

a storage medium in the core network;

a database stored in the storage medium that stores information associating the machine identity with an associated QoS parameter;

a subsystem in the core network that determines the associated QoS parameter for the first device based on the machine identity;

a subsystem in the core network that assigns an assigned priority for the message based on the associated QoS parameter, the assigned priority selected from among a first priority and a second lower priority;

a subsystem that assigns the message to an assigned input queue in the radio network based on the assigned priority, the assigned input queue selected from among a first input queue having a first associated delay into which a first set of assigned messages having the first priority are assigned and a second input queue having a second associated delay into which a second set of assigned messages having the second lower priority are assigned.

8. The system of claim 7 wherein the associated QoS parameter is latency.

9. The system of claim 8 wherein the first input queue has a delay that is shorter than the delay of the second input queue.

10. The system of claim 7 further comprising a transmitter that transmits a first set of messages in the first input queue, before transmitting a second set of messages in the second input queue.

11. The system of claim 7 wherein the first set of assigned messages in the first input queue have low latency and second set of assigned messages in the second input queue have higher latency.

12. The system of claim 7 wherein the first input queue and the second input queue are located in an eNode B access point.
