System and method for partially count-based allocation of vocoder resources
View Patent ↗A system and method for allocating vocoder resources for interconnect calls includes consideration of what percentage of interconnect calls have been assigned to a particular vocoder type. In an embodiment a vocoder type is assigned to a given interconnect call based on a comparison of the available capacity of the telecommunications network to one or more threshold values, and a determination on whether or not the percentage of interconnect calls assigned to a given vocoder type has exceeded a threshold percentage. In certain embodiments, the vocoder is adapted to operate in one of at least two possible types, where the first type is characterized by a higher voice quality, but a lower network capacity, than the second type.
1. A method for assigning a vocoder type to an interconnect call transported over a telecommunications network, comprising the acts of:
receiving a request to transport the interconnect call;
determining if an available network capacity of the telecommunications network is greater than a threshold value;
determining whether a desired threshold percentage of calls assigned to a particular vocoder type has been reached, wherein the desired threshold percentage is based on a total number of active calls of a cell of the telecommunications network; and
assigning at least one of a first vocoder type and a second vocoder type to the interconnect call based on whether the available network capacity is greater than the threshold value and on whether the desired threshold percentage has been reached, wherein said first vocoder type provides a higher voice quality for the interconnect call than the second vocoder type.
2. The method of claim 1 wherein if the available network capacity is greater than the threshold value, the first vocoder type is assigned to the interconnect call.
3. The method of claim 1 wherein if the available network capacity is not greater than the threshold value, and the desired threshold percentage has been reached, the first vocoder type is assigned to the interconnect call.
4. The method of claim 3 wherein said first vocoder type is assigned to the interconnect call only if there is an available channel of said telecommunications network.
5. The method of claim 1 wherein if the available network capacity is not greater than the threshold value, and the desired threshold percentage has not been reached, the second vocoder type is assigned to the interconnect call.
6. The method of claim 1 wherein said second vocoder type is associated with interleaving a higher number of voice calls onto a single radio frequency channel of the telecommunications network, and said first vocoder type is associated with interleaving a lower number of voice calls onto the single radio frequency channel.
7. The method of claim 6 wherein said higher number of voice calls is six and said lower number of voice calls is three.
8. The method of claim 1 wherein said threshold value comprises at least one of a congestion relief threshold and a split threshold, wherein said congestion relief threshold is indicative of how readily congestion relief measures are to be undertaken by the telecommunications network, and said split threshold is indicative of how readily said second vocoder type is to be assigned.
9. The method of claim 8 wherein said threshold value is based on the sum of the congestion relief threshold and the split threshold.
10. A system for increasing capacity in a telecommunications network, comprising:
a vocoder adapted to operate in one of at least a first vocoder type and a second vocoder type based on whether an available network capacity of the telecommunications network is greater than a threshold value, and on whether a desired threshold percentage of calls assigned to a particular vocoder type has been reached, wherein the first vocoder type provides a higher voice quality for an interconnect call than the second vocoder type, and wherein the threshold value comprises at least one of a congestion relief threshold and a split threshold, wherein said congestion relief threshold is indicative of how readily congestion relief measures are to be undertaken by the telecommunications network, and said split threshold is indicative of how readily said second vocoder type is to be assigned.
11. The system of claim 10 wherein if the available network capacity is greater than the threshold value, the first vocoder type is assigned to the interconnect call.
12. The system of claim 10 wherein if the available network capacity is not greater than the threshold value, and the desired threshold percentage has been reached, the first vocoder type is assigned to the interconnect call.
13. The system of claim 12 wherein said first vocoder type is assigned to the interconnect call only if there is an available channel of said telecommunications network.
14. The system of claim 10 wherein if the available network capacity is not greater than the threshold value, and the desired threshold percentage has not been reached, the second vocoder type is assigned to the interconnect call.
15. The system of claim 10 wherein said second vocoder type is associated with interleaving a higher number of voice calls onto a single radio frequency channel of the telecommunications network, and said first vocoder type is associated with interleaving a lower number of voice calls onto the single radio frequency channel.
16. The system of claim 15 wherein said higher number of voice calls is six and said lower number of voice calls is three.
17. The system of claim 10 wherein the desired threshold percentage of calls assigned to the second vocoder type is based on a total number of active calls of a cell of the telecommunications network.
18. The system of claim 10 wherein said threshold value is based on the sum of the congestion relief threshold and the split threshold.
19. A method comprising the acts of:
comparing an available network capacity of the telecommunications network to a threshold value;
determining if a desired threshold percentage of calls assigned to a particular vocoder type has been reached; and
selecting one of at least a first vocoder type and a second vocoder type based on said comparing and said determining, wherein said first vocoder type provides a higher voice quality and lower network capacity than the second vocoder type, and wherein the threshold value comprises at least one of a congestion relief threshold and a split threshold, wherein said congestion relief threshold is indicative of how readily congestion relief measures are to be undertaken by the telecommunications network, and said split threshold is indicative of how readily said second vocoder type is to be selected.
20. The method of claim 19 wherein if the available network capacity is greater than the threshold value, the first vocoder type is selected.
21. The method of claim 19 wherein if the available network capacity is less than the threshold value, and the desired threshold percentage has been reached, the first vocoder type is selected.
22. The method of claim 21 wherein said first vocoder type is selected only if there is an available channel of said telecommunications network.
23. The method of claim 19 wherein if the available network capacity is less than the threshold value, and the desired threshold percentage has not been reached, the second vocoder type is selected.
24. The method of claim 19 wherein if the available network capacity is equal to the threshold value, said selecting comprises selected the first vocoder type if the desired threshold percentage has been reached and selecting the second vocoder type if the desired threshold percentage has not been reached.
25. The method of claim 19 wherein if the available network capacity is equal to the threshold value, said selecting comprises selecting the first vocoder type.
26. The method of claim 19 wherein said second vocoder type is associated with interleaving a higher number of voice calls onto a single radio frequency channel of the telecommunications network, and said first vocoder type is associated with interleaving a lower number of voice calls onto the single radio frequency channel.
27. The method of claim 26 wherein said higher number of voice calls is six and said lower number of voice calls is three.
28. The method of claim 19 wherein said threshold value is based on the sum of the congestion relief threshold and the split threshold.
29. The method of claim 19 wherein determining if the desired threshold percentage of calls has been reached comprises determining whether the desired threshold percentage of calls assigned to the second vocoder type has been reached where the desired threshold percentage is based on a total number of active calls of a cell of the telecommunications network.
