Abstract

A method and apparatus for saving network resources in a CDMA2000 network, the method comprising the steps of receiving a data packet for a wireless data device at a base station controller in the CDMA2000 network; determining a frame transport capability of a forward common channel; checking whether the data packet falls within the frame transport capability; and if the data packet falls within the frame transport capability, encapsulating the data packet as a data burst message; and sending the data burst message over the forward common channel, wherein the sending step over the forward common channel precludes a dedicated data traffic channel being established for the data packet thereby saving network resources on the CDMA2000 network.

Claims

1. A method on a processing element comprising:

receiving a data burst message at a communications subsystem of the processing device;

checking if a burst type of the data burst message is packet data; and

if the burst type is packet data;

reforming a data packet from the data burst message; and

passing the data packet to an receiving entity.

2. The method of claim 1, wherein the processing element is a wireless data device.

3. The method of claim 2, wherein the receiving is done over a forward common channel.

4. The method of claim 2, wherein the reforming step comprises removing a data burst header from the data burst message.

5. The method of claim 2, wherein the receiving entity is an application layer on the wireless data device.

6. The method of claim 1, wherein the processing element is a network element.

7. The method of claim 6, wherein the network element includes a base station controller.

8. The method of claim 6, wherein the network element is a packet data serving node.

9. The method of claim 6, wherein the receiving is done over a reverse access channel.

10. The method of claim 6, further comprising keeping a mapping table to associate the data burst message with an International Mobile Station Identity of a wireless data device.

11. The method of claim 6, further comprising keeping a mapping table to associate the data burst message with an email address of a wireless data device.

12. The method of claim 6, wherein the receiving entity is the Internet.

13. A wireless data device, comprising:

a communications subsystem configured to receive a data burst message on a forward common channel and

a processor configured to;

check if a burst type of the data burst message is packet data; and

if the burst type is packet data,

reform a data packet from the data burst message; and

pass the data packet to an application layer on the wireless device.

14. The wireless data device of claim 13, wherein the reforming comprises removing a data burst header from the data burst message.

15. A network element, comprising:

a communications subsystem configured to receive a data burst message on a reverse access channel and

a processor configured to;

check if a burst type of the data burst message is packet data; and

if the burst type is packet data,

reform a data packet from the data burst message for transport over the Internet.

16. The network element of claim 15, wherein the network element includes a base station controller.

17. The network element of claim 15, wherein the network element is a packet data serving node.

18. The network element of claim 15, further comprising memory configured to keep a mapping table to associate the data burst message with an International Mobile Station Identity of a wireless data device.

19. The network element of claim 15, further comprising memory configured to keep a mapping table to associate the data burst message with an email address of a wireless data device.

20. The network element of claim 15, wherein the reforming includes decapsulating the data burst message.
