Systems and methods for integrated unicast and multicast traffic management
View Patent ↗Methods for managing network resources for multicast streams based on unicast load conditions of a base station in a communications network include monitoring unicast load conditions of the base station, and adjusting bearer properties for a multicast stream based on the unicast load conditions. A broadcast provisioning server (BPS) manages network resources for multicast streams based on unicast load conditions of a base station in a communications network. The BPS may be configured to monitor unicast load conditions of the base station and adjust bearer properties for a multicast stream based on the unicast load conditions.
1. A method for managing network resources for multicast streams in a communications network, the method comprising:
receiving, by a network element unicast load condition information from the base station, the base station having received the unicast load condition information from a user equipment being serviced by the base station;
determining a unicast resource availability based on the received unicast load condition information;
receiving at least one quality of service (QoS) measurement associated with a unicast transmission from the base station, the base station having received the QoS measurement from the user equipment being serviced by the base station;
determining at least one QoS value based on the at least one QoS measurement; and
adjusting, by the network element, bearer properties for a multicast stream based on the determined unicast resource availability, the determined at least one QoS value, a first threshold and a second threshold.
2. The method of claim 1 , wherein the adjusting comprises at least one of:
decreasing the bearer properties by a decrease amount if the unicast resource availability is determined to be above the first threshold;
increasing the bearer properties by an increase amount if the unicast resource availability is determined to be below the first threshold; and
maintaining the bearer properties if the unicast resource availability is determined to be equal to the first threshold.
3. The method of claim 2 , wherein a policy defines the first threshold, the increase amount, and the decrease amount.
4. The method of claim 2 , wherein the adjusting further comprises at least one of:
decreasing the bearer properties by the decrease amount if the unicast resource availability is determined to be above the first threshold and the QoS value is above the second threshold;
increasing the bearer properties by the increase amount if the unicast resource availability is determined to be below the first threshold and the QoS value is below the second threshold; and
maintaining the bearer properties if one of (i) the unicast resource availability is determined to be equal to the first threshold and (ii) the QoS value is determined to be equal to the second threshold.
5. The method of claim 4 , wherein the policy further defines
the second threshold and how to calculate the QoS value based on the QoS measurement, and
the QoS measurement being at least one of call drop rate, a signal to noise ratio, a measure of throughput, a delay, a jitter, and a handover success rate.
6. The method of claim 5 , wherein
the bearer properties include a guaranteed bit rate (GBR), and
the policy defines the increase amount to include a GBR increase amount for increasing the GBR and the decrease amount to include a GBR decrease amount for decreasing the GBR.
7. The method of claim 6 , wherein
the bearer properties further include a maximum bit rate (MBR), and
the policy defines the increase amount to include a MBR increase amount for increasing the MBR and the decrease amount to include a MBR decrease amount for decreasing the MBR.
8. The method of claim 7 , wherein
the bearer properties further include a QoS class identifier (QCI), and
the policy defines the increase amount to include a QCI increase amount for increasing the QCI and the decrease amount to include a QCI decrease amount for decreasing the QCI.
9. A broadcast provisioning server (BPS) configured to manage network resources for multicast streams in a communications network, the BPS comprising:
a memory having computer readable instructions stored therein; and
a processor, which when executing the instructions, is configured to:
receive unicast load condition information from a base station, the base station having received the unicast load condition information from a user equipment being serviced by the base station;
determine a unicast resource availability based on the received unicast load condition information;
receive at least one quality of service (QoS) measurement associated with a unicast transmission from the base station, the base station having received the QoS measurement from the user equipment being serviced by the base station;
determine at least one QoS value based on the at least one of QoS measurement; and
adjust bearer properties for a multicast stream based on the determined unicast resource availability, the determined at least one QoS value, a first threshold and a second threshold.
10. The BPS of claim 9 , wherein the processor is further configured to adjust the bearer properties by:
decreasing the bearer properties by a decrease amount if the unicast resource availability is determined to be above the first threshold;
increasing the bearer properties by an increase amount if the unicast resource availability is determined to be below the first threshold; and
maintaining the bearer properties if the unicast resource availability is determined to be equal to the first threshold.
11. The BPS of claim 10 , wherein a policy defines the first threshold, the increase amount, and the decrease amount.
12. The BPS of claim 10 , wherein the processor is further configured to adjust the bearer properties by:
decreasing the bearer properties by the decrease amount if the unicast resource availability is determined to be above the first threshold and the QoS value is above the second threshold;
increasing the bearer properties by the increase amount if the unicast resource availability is determined to be below the first threshold and the QoS value is below the second threshold; and
maintaining the bearer properties if one of (i) the unicast resource availability is determined to be equal to the first threshold and (ii) the QoS value is determined to be equal to the second threshold.
13. The BPS of claim 12 , wherein the policy further defines
the second threshold and how to calculate the QoS value based on the QoS measurement, and
the QoS measurement being at least one of call drop rate, a signal to noise ratio, a measure of throughput, a delay, a jitter, and a handover success rate.
14. The BPS of claim 13 , wherein
the bearer properties include a guaranteed bit rate (GBR), and
the policy defines the increase amount to include a GBR increase amount for increasing the GBR and the decrease amount to include a GBR decrease amount for decreasing the GBR.

16. The BPS of claim 15 , wherein
the bearer properties further include a QoS class identifier (QCI), and
the policy defines the increase amount to include a QCI increase amount for increasing the QCI and the decrease amount to include a QCI decrease amount for decreasing the QCI.
