Identifying data and/or control packets in wireless communication

1. A method of wireless communication, comprising:

receiving an Internet protocol (IP) packet including at least one of a voice payload encoded according to a real-time transport protocol (RTP) or control information encoded according to a real-time transport control protocol (RTCP);

determining whether the IP packet includes a voice payload or control information based on at least one of a packet size and an arrival frequency of at least one IP packet; and

routing the IP packet to a first radio bearer when the IP packet includes a voice payload and a second radio bearer when the IP packet includes control information; and

determining a packet size mask based on at least two previous IP packets.

2. The method of claim 1 , wherein determining whether the IP packet includes a voice payload or control information comprises determining whether the IP packet is encoded according to the Real Time Protocol or the Real Time Control Protocol.

3. The method of claim 1 , wherein determining the packet size mask comprises determining a most frequent packet size based on at least one previous IP packet.

4. The method of claim 1 , wherein determining whether the IP packet includes a voice payload or control information comprises determining whether the IP packet includes a voice payload or control information based on the packet size mask.

5. The method of claim 1 , comprising determining a port number associated with the IP packet.

6. The method of claim 5 , wherein determining whether the IP packet includes a voice payload or control information comprises determining whether the IP packet includes a voice payload or control information based on the port number.

7. The method of claim 6 , comprising determining at least one voice payload port number associated with at least one previous IP packet that includes a voice payload.

8. The method of claim 7 , comprising determining at least one control information port number associated with at least one previous IP packet that includes control information.

9. The method of claim 8 , wherein determining whether the IP packet includes a voice payload or control information comprises comparing the port number associated with the IP packet with at least one of the at least one voice payload port number and the at least one control information port number.

10. The method of claim 1 , wherein determining whether the IP packet includes a voice payload or control information comprises determining whether an IP packet to be transmitted over an uplink includes a voice payload or control information based on at least one of a packet size and an arrival frequency of at least one IP packet.

11. The method of claim 1 , wherein determining whether the IP packet includes a voice payload or control information comprises determining whether an IP packet to be transmitted over a downlink includes a voice payload or control information based on at least one of a packet size and an arrival frequency of at least one packet.

12. The method of claim 1 , comprising routing the IP packet to a radio bearer based on whether the IP packet includes a voice payload or control information.

13. The method of claim 12 , comprising transmitting the IP packet over either the first radio bearer or the second radio bearer.

14. The method of claim 13 , wherein transmitting the IP packet comprises transmitting the IP packet over the first radio bearer using an acknowledged mode or transmitting the IP packet over the second radio bearer using an unacknowledged mode.
