Abstract

A component in a telecommunications network including a processor configured, responsive to receiving a scheduling request from a user equipment (UE), to grant a minimum level of resource capacity to the UE for an uplink transmission from the UE to the component. The processor further configured to determine the minimum level of resource capacity based on an expected data packet payload and on a condition of a communications channel between the component and the UE.

Claims

1. A component in a telecommunications network, comprising:

a processor configured, responsive to receiving a scheduling request from a user equipment (UE), to grant a minimum level of resource capacity to the UE for an uplink transmission from the UE to the component, the processor further configured to determine the minimum level of resource capacity based on an expected data packet payload and on a condition of a communications channel between the component and the UE.

2. The component of claim 1 wherein the processor further configured to determine the minimum level of resource capacity based on the expected data packet payload and on the condition of a communications channel between the component and the UE, the expected data packet payload size is a Compressed VoIP packet size.

3. The component of claim 1 wherein the component configured to receive from the UE, responsive to the UE receiving the grant of the minimum level of resource capacity to send the component, a data packet that is one of:

a VoIP data packet;

or

a buffer status report.

4. The component of claim 3 wherein, when the data packet is the VoIP data packet, the component allocates a semi-persistent.

5. The component of claim 3 wherein, when the data packet is the buffer status report, the component allocates a dynamic resource.

6. The component of claim 3 wherein, when the data packet is not received successfully, the minimum level of resource capacity is increased and the data packet is transmitted via the increased-capacity resource.

7. The component of claim 1, wherein the component is an enhanced node B.

8. A user equipment (UE), comprising:

a processor to promote communication of a scheduling request to an enhanced node B and to receive from the enhanced node B a grant of a minimum level of resource capacity for an uplink to the enhanced node B, the minimum level of resource capacity based on an expected data packet payload and on a condition of a communications channel between the enhanced node B and the UE, the processor configured to promote use of the grant of the minimum level of resource capacity to send the enhanced node B a data packet that is one of;

a VoIP data packet, or

a buffer status report.

9. The UE of claim 8 wherein the minimum level of resource capacity based on the expected data packet payload and on the condition of a communications channel between the enhanced node B and the UE, the expected data packet payload size is a Compressed VoIP packet size.

10. The UE of claim 8 wherein, when the data packet is the VoIP data packet, the UE configured to receive from the enhanced node B a semi-persistent resource allocated to the UE.

11. The UE of claim 8 wherein, when the data packet is the buffer status report, the UE configured to receive from the enhanced node B a dynamic resource allocated to the UE.

12. A method for establishing an uplink resource for a Voice over Internet Protocol (VoIP) call comprising:

sending a scheduling request for the uplink resource;

receiving from the uplink resource a grant of a minimum resource;

sending a VoIP data packet; and

receiving a grant from the uplink resource of a semi-persistent resource with a capacity substantially similar to a capacity of the minimum resource.

13. The method of claim 12 wherein the capacity of the minimum resource is determined based on a minimum size of a compressed VoIP payload and on a condition of a communications channel between a first component sending the scheduling request and a second component where the grant of the minimum resource is received from.

14. The method of claim 13 wherein the first component is a user equipment.

15. The method of claim 12 wherein, when the VoIP data packet is not received successfully, the capacity of the minimum resource is increased and the VoIP data packet is transmitted via the increased-capacity minimum resource.

16. A method for establishing an uplink resource for a Voice over Internet Protocol (VoIP) call comprising:

receiving a scheduling request for the uplink resource;

granting a minimum resource;

receiving a VoIP data packet; and

responsive to receiving the VoIP data packet, granting a semi-persistent resource with a capacity substantially similar to a capacity of the minimum resource.

17. The method of claim 16 wherein the capacity of the minimum resource is determined based on a minimum size of a compressed VoIP payload and on a condition of a communications channel between a first component where the scheduling request is received from and a second component granting the minimum resource.

18. The method of claim 17 wherein the second component is an enhanced node B.

19. The method of claim 16 wherein, when the VoIP data packet is not received successfully, the capacity of the minimum resource is increased and the VoIP data packet is transmitted via the increased-capacity minimum resource.
