Methods and apparatuses for dynamic backhaul bandwidth management in wireless networks

1. A method of backhaul bandwidth management executed by a backhaul network entity, the method comprising:

receiving, by the backhaul network entity, a backhaul bandwidth change request message from an access point of a wireless access network that includes a requested backhaul bandwidth level based on a potential mobile subscriber user equipment (UE) load change determined by the access point;

calculating, by the backhaul network entity, an available backhaul bandwidth level corresponding to a backhaul; and

transmitting, by the backhaul network entity, a backhaul bandwidth change acknowledgement message to the access point that includes an approved backhaul bandwidth level when the available backhaul bandwidth level supports the requested backhaul bandwidth level.

2. The method of claim 1 , wherein the backhaul bandwidth change acknowledgement message includes an approved backhaul bandwidth level.

3. The method of claim 2 , wherein the approved backhaul bandwidth level equals the requested backhaul bandwidth level.

4. The method of claim 1 , further comprising:

determining that the available backhaul bandwidth level does not support the requested backhaul bandwidth level;

calculating an approved backhaul bandwidth level based on the determined available backhaul bandwidth level, wherein the approved backhaul bandwidth level is less than the requested backhaul bandwidth level; and

transmitting a backhaul bandwidth change denial based on determining that the available backhaul bandwidth level does not support the requested backhaul bandwidth level, wherein the backhaul bandwidth change denial includes the approved backhaul bandwidth level.

5. An apparatus for backhaul bandwidth management, comprising:

a backhaul network entity, the backhaul network entity including:

a backhaul bandwidth change request message receiving module configured to receive a backhaul bandwidth change request message from an access point of a wireless access network that includes a requested backhaul bandwidth level based on a potential mobile subscriber user equipment (UE) load change determined by the access point;

an available backhaul bandwidth level calculating module configured to calculate an available backhaul bandwidth level corresponding to a backhaul; and

a message transmitting module configured to transmit a backhaul bandwidth change acknowledgement message to the access point that includes an approved backhaul bandwidth level when the available backhaul bandwidth level supports the requested backhaul bandwidth level.

6. The apparatus of claim 5 , wherein the backhaul bandwidth change acknowledgement message includes an approved backhaul bandwidth level.

7. The apparatus of claim 6 , wherein the approved backhaul bandwidth level equals the requested backhaul bandwidth level.

8. The apparatus of claim 5 , further comprising:

a comparing module configured to determine that the available backhaul bandwidth level does not support the requested backhaul bandwidth level; and

an approved backhaul bandwidth level calculating module configured to calculate an approved backhaul bandwidth level based on the available backhaul bandwidth level, wherein the approved backhaul bandwidth level is less than the requested backhaul bandwidth level; and

wherein the message transmitting module is further configured to transmit a backhaul bandwidth change denial based on determining that the available backhaul bandwidth level does not support the requested backhaul bandwidth level, wherein the backhaul bandwidth change denial includes the approved backhaul bandwidth level.

9. At least one non-transitory machine readable medium comprising a plurality of instructions that in response to being executed on a computing device, cause the computing device to:

receive, by a backhaul network entity, a backhaul bandwidth change request message from an access point of a wireless access network that includes a requested backhaul bandwidth level based on a potential mobile subscriber user equipment (UE) load change determined by the access point;

calculate, by the backhaul network entity, an available backhaul bandwidth level corresponding to a backhaul; and

transmit, by the backhaul network entity, a backhaul bandwidth change acknowledgement message to the access point that includes an approved backhaul bandwidth level when the available backhaul bandwidth level supports the requested backhaul bandwidth level.

10. The at least one machine readable medium of claim 9 , wherein the backhaul bandwidth change acknowledgement message includes an approved backhaul bandwidth level.

11. The at least one machine readable medium of claim 10 , wherein the approved backhaul bandwidth level equals the requested backhaul bandwidth level.

12. The at least one machine readable medium of claim 9 , further comprising a plurality of instructions that in response to being executed on a computing device, cause the computing device to:

determine that the available backhaul bandwidth level does not support the requested backhaul bandwidth level;

calculate an approved backhaul bandwidth level based on the available backhaul bandwidth level, wherein the approved backhaul bandwidth level is less than the requested backhaul bandwidth level; and

transmit a backhaul bandwidth change denial based on determining that the available backhaul bandwidth level does not support the requested backhaul bandwidth level, wherein the backhaul bandwidth change denial includes the approved backhaul bandwidth level.
