Abstract

A method and apparatus for user data traffic handling for an EVDO enabled hybrid mode mobile device, the method having the steps of: blocking a system selection at the mobile device until no EVDO traffic state exists, the blocking step includes either monitoring whether a user changes a scan mode on the mobile device; and if the user changes the scan mode, checking whether the mobile device is in an EVDO traffic state; and if yes delaying a system selection until the EVDO traffic state is ended, or monitoring whether a user is in an EVDO traffic state, and if yes, preventing a user from accessing a scan mode menu on the mobile device.

Claims

1. A method for user data traffic handling for an Evolution Data Only or Data Optimized ‘

EVDO’

enabled Code Division Multiple Access ‘

CDMA’

prioritized hybrid communications mode mobile device, the method comprising the steps of;

blocking a voice services system selection at the mobile device until no EVDO traffic state exists.

2. The method of claim 1, wherein the blocking step includes:

monitoring whether a user changes a scan mode on the mobile device; and

if the user changes the scan mode, checking whether the mobile device is an EVDO traffic state; and

if yes

delaying said voice services system selection until the EVDO traffic state is ended.

3. The method of claim 1, wherein the blocking step includes the steps of:

a) monitoring whether the mobile device is an EVDO traffic state, and if yes, preventing the user from accessing a scan mode menu on the mobile device.

6. The method of claim 2, wherein the mobile device performs the voice services system selection once the EVDO traffic state ends.

12. The method of claim 1, wherein the blocking step further includes the step of:

hiding the scan mode selection menu when the mobile device is an EVDO traffic state

4. (canceled)

5. (canceled)

7. An Evolution Data Only or Data Optimized ‘

EVDO’

enabled Code Division Multiple Access ‘

CDMA’

prioritized hybrid communications mode mobile device characterized by;

means for blocking a voice services system selection at the mobile device until no EVDO traffic state exists.

8. The mobile device of claim 7, wherein the means for blocking includes:

means for monitoring whether a user changes a scan mode on the mobile device;

means for checking whether the mobile device is in an EVDO traffic state; and

means for delaying said voice services system selection, the means for delaying the voice services system selection delaying voice services system selection if the means for monitoring whether the user changes the scan mode detects that the user changed the scan mode and if the means for checking finds the mobile decive is in an EVDO traffic state.

9. The mobile device of claim 7, wherein the blocking means includes:

means for monitoring whether the mobile device is an EVDO traffic state; and

means for preventing a user from accessing a scan mode menu on the mobile device if the means for monitoring detects the mobile device is in an EVDO traffic state.

13. The mobile device of claim 7, wherein the means for blocking includes means for hiding a scan mode selection menu, the menas for hiding the scan mode selection menu being capable of hiding the scan mode selection menu when the mobile device is in an EVDO traffic state.
