Override vocoder capacity operating point allocation
View Patent ↗Embodiments disclosed herein provide systems and methods for override vocoder capacity operating point (COP) allocation. In a particular embodiment, a method provides determining a communication load on a wireless access node. Based on the communication load, the method provides allocating a first COP for a vocoder, wherein the vocoder is used on voice communications exchanged with the wireless access node. The method further provides determining a frame error rate of a wireless communication link between a wireless communication device and the wireless access node. If the frame error rate indicates that a COP of the wireless communication link should be lower than the first COP, the method provides allocating an override COP to the COP of the wireless communication link based on the frame error rate.
1. A method of operating a wireless communication system, comprising:
determining a communication load on a wireless communication link between a wireless access node and a wireless communication device, and based on the communication load, allocating a first vocoder capacity operating point (COP) in the wireless communication device,
if the wireless access node determines the communication load, then the wireless access node will also allocate the first vocoder COP;
if another system determines the communication load, then the other system will send information about the communication load to the wireless access node so that the wireless access node can allocate the first vocoder COP;
determining a frame error rate of the wireless communication link between the wireless communication device and the wireless access node; and
if the frame error rate exceeds a threshold, then overriding the first vocoder COP of the wireless communication link with a second vocoder COP, wherein the first vocoder COP and the second vocoder COP are integer values between 0-7 and are used on voice communications exchanged with the wireless access node and the wireless communication device.
2. The method of claim 1 , wherein if the frame error rate is greater than 5% then the second vocoder COP should be 0.
3. The method of claim 1 , wherein if the frame error rate is between 4% and 5% then the second vocoder COP should be 1.
4. The method of claim 1 , wherein if the frame error rate is between 3% and 4% then the second vocoder COP should be 2.
5. The method of claim 1 , wherein if the frame error rate is between 2% and 3% then the second vocoder COP should be 3.
6. The method of claim 1 , wherein if the frame error rate is between 1% and 2% then the second vocoder COP should be 4.
7. The method of claim 1 , wherein if the frame error rate is between 0% and 1% then the second vocoder COP should be one of 5, 6, or 7.
8. The method of claim 1 , wherein the communication load is a radio frequency (RF) load.
9. The method of claim 1 , wherein the vocoder is an Enhanced Variable Rate Codec-B (EVRC-B).
10. A wireless communication system, comprising:
a communication interface configured to receive load information about a communication load on a wireless communication link between a wireless access node and a wireless communication device and error information about a frame error rate of the wireless communication link between the wireless communication device and the wireless access node;
a processing system configured to use the load information to determine the communication load on the wireless access node, based on the communication load, allocate a first vocoder capacity operating point (COP) in the wireless communication device, use the error information to determine the frame error rate of the wireless communication link between the wireless communication device and the wireless access node, and, if the frame error rate exceeds a threshold then overriding the first vocoder COP of the wireless communication link with a second vocoder COP, wherein the first vocoder COP and the second vocoder COP are integer values between 0-7 and are used on voice communications exchanged with the wireless access node and the wireless communication device
if the wireless access node determines the communication load, then the wireless access node will also allocate the first vocoder COP;
if another system determines the communication load, then the other system will send information about the communication load to the wireless access node so that the wireless access node can allocate the first vocoder COP.

12. The system of claim 10 , wherein if the frame error rate is between 4% and 5% then the second vocoder COP should be 1.
13. The system of claim 10 , wherein if the frame error rate is between 3% and 4% then the second vocoder COP should be 2.
14. The system of claim 10 , wherein if the frame error rate is between 2% and 3% then the second vocoder COP should be 3.
15. The system of claim 10 , wherein if the frame error rate is between 1% and 2% then the second vocoder COP should be 4.
16. The system of claim 10 , wherein if the frame error rate is between 0% and 1% then the second vocoder COP should be one of 5, 6, or 7.
17. The system of claim 10 , wherein the communication load is a radio frequency (RF) load.
18. The system of claim 10 , wherein the vocoder is an Enhanced Variable Rate Codec-B (EVRC-B).
