Abstract

Various example embodiments are disclosed herein. According to an example embodiment, a technique may include allocating periodic resources to a mobile station in a wireless network for transmission of voice data, receiving from the mobile station an indication of a start of a silence period, and adjusting, based on the receiving of the indication of a start of silence period, the allocating of the periodic resources from a size and period of resource for the voice data to a size and period of resource for a silence indication (SID) frame. Alternatively, in response to receiving an indication of a start of silence period, the allocating of periodic resources for the VoIP voice data may be temporarily stopped during the silence period.

Claims

1. A method comprising:

allocating periodic resources to a mobile station in a wireless network for transmission of voice data;

receiving from the mobile station an indication of a start of a silence period;

adjusting, based on the receiving of the indication of a start of silence period, the allocating of the periodic resources from a size and period of resource for the voice data to a size and period of resource for a silence indication (SID) frame;

receiving from the mobile station an indication of an end of the silence period; and

re-adjusting, based on the receiving of the indication of the end of the silence period, the allocating of the periodic resources from the size and period of resource for the silence indication (SID) frame to the size and period of resource for voice data, wherein the re-adjusting includes transmitting a persistent information element to reallocate persistent allocation from the silence indication (SID) frame transmission to the voice data transmission.

2. The method of claim 1 and further comprising receiving from the mobile station the size and period of the silence indication (SID) frame.

3. The method of claim 1 and further comprising receiving from the mobile station the size and period of the silence indication (SID) frame via a Dynamic Service Addition procedure or a Dynamic Service Change procedure.

4. The method of claim 1, wherein the period of the silence indication (SID) frame is variable, the method further comprising:

receiving, from the mobile station, a channel quality information channel (CQICH) codeword indicating a request for resources, the requested resources to be used by the mobile station to transmit the silence indication (SID) frame during the silence period.

5. The method of claim 1 and further comprising allocating to the mobile station during the silence period a resource request channel, wherein receiving a first value from the mobile station via the resource request channel indicates a request for allocation of uplink resources for the mobile station to transmit voice data, and wherein receiving a second value from the mobile station via the resource request channel indicates a request for allocation of uplink resources for the mobile station to transmit a silence indication (SID) frame.

6. The method of claim 1 and further comprising:

receiving voice data from the mobile station via the resources allocated for transmission of voice data; and

forwarding the received voice data to a second station, the mobile station and the second station being associated with a VoIP connection.

7. The method of claim 1 wherein the allocating periodic resources comprises periodically allocating, via extended real-time polling service (eRTPS), uplink resources to the mobile station for the transmission of VoIP voice data.

8. The method of claim 1 wherein the allocating periodic resources comprises providing a persistent resource allocation to the mobile station that allocates recurring periodic resources to the mobile station for the transmission of voice over IP (VoIP) voice data.

9. The method of claim 1:

wherein the allocating periodic resources for voice data comprises providing a persistent resource allocation to the mobile station that allocates recurring periodic resources to the mobile station, the recurring resources having a size and period for the transmission of voice over IP (VoIP) voice data; and

wherein the adjusting allocating of the periodic resources comprises adjusting the persistent resource allocation to provide a recurring resource to the mobile station having a size and period for the silence indication (SID) frame.

10. A method comprising:

allocating periodic resources to a mobile station in a wireless network for transmission of voice data;

receiving from the mobile station an indication of a start of a silence period;

adjusting, based on the receiving of the indication of a start of silence period, the allocating of the periodic resources from a size and period of resource for the voice data to a size and period of resource for a silence indication (SID) frame;

receiving a silence indication (SID) frame from the mobile station via the resources allocated for the SID frame;

forwarding the received frame to a second station, the mobile station and the second station being associated with a VoIP connection; and

de-allocating the resources that were allocated to the mobile station for the SID frame;

regenerating and forwarding the SID frame to the second station based on the received SID frame and the period of the SID frame.
