Abstract

A method and apparatus for reverse and forward link dynamic packet transport to and from a wireless data device in a CDMA2000 network, the method comprising the steps of: determining a frame transport capability of a reverse access channel or a forward common channel; checking whether a 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; sending the data burst message over the reverse access channel or forward common channel; receiving the data burst message; and reforming the data packet.

Claims (32)

1. A method for saving battery life on a wireless data device and for saving network resources in a CDMA2000 network, said method being performed at the wireless data device and comprising the steps of:

if a dedicated traffic channel is not established between the wireless data device and the CDMA2000 network,

determining a frame transport capability of a reverse access channel;

checking whether a size of a data packet falls within said frame transport capability; and

if the size of said data packet falls within said frame transport capability encapsulating said data packet as a data burst message; and

sending said data burst message over said reverse access channel and

if a dedicated voice traffic channel is established,

determining whether the dedicated voice traffic channel supports data transmission;

if said dedicated voice traffic channel supports data transmission,

determining a frame transport capability of said dedicated voice traffic channel;

checking whether the size of said data packet falls within said frame transport capability; and

if the size of said data packet falls within said frame transport capability encapsulating said data packet as a data burst message; and

sending the data burst message over said dedicated voice traffic channel;

wherein said sending step over said reverse access channel or over the dedicated voice traffic channel precludes a dedicated data traffic channel being established for said data burst message thereby saving battery life of said wireless data device and network resources on said CDMA2000 network.

2. The method of claim 1 , wherein said encapsulating step further adds an email address of said wireless device to said data burst message if said data packet is email.

3. The method of claim 1 , wherein the data burst message is received at a base station controller.

4. The method of claim 3 , where said base station controller further forwards the data burst packet to a packet data serving node if the data burst packet is comprised of packet data.

5. The method of claim 4 , wherein said packet data serving node reforms said data burst message.

6. A wireless device adapted to saving battery life network resources in a CDMA2000 network, said wireless device characterized by:

if a dedicated traffic channel is not established between the wireless data device and the CDMA2000 network,

means for determining a frame transport capability of a reverse access channel;

means for checking whether a size of a data packet falls within said frame transport capability; and

if the size of said data packet falls within said frame transport capability means for encapsulating said data packet as a data burst message; and

means for sending said data burst message over said reverse access channel; and

if a dedicated voice traffic channel is established,

means for determining whether the dedicated voice traffic channel supports data transmission;

if said dedicated voice traffic channel supports data transmission,

means for determining a frame transport capability of said dedicated voice traffic channel;

means for checking whether the size of said data packet falls within said frame transport capability; and

if the size of said data packet falls within said frame transport capability means for encapsulating said data packet as a data burst message; and

means for sending the data burst message over said dedicated voice traffic channel;

wherein said means for sending over said reverse access channel or over the dedicated voice traffic channel precludes a dedicated data traffic channel being established for said data burst message thereby saving battery life of said wireless data device and network resources on said CDMA2000 network.
