Abstract

A method includes storing a first Serving Grant (SG) value for use in a first serving cell, entering a second serving cell, receiving an information element from a higher layer, maintaining the first SG value if the information element does not include a second SG value, and changing the first SG value to the second SG value if the information element includes a second SG value.

Claims

1. A method comprising:

storing a first Serving Grant (SG) value for use in a first serving cell;

receiving an information element from a higher layer during transition to a second serving cell;

maintaining said first SG value if said information element does not comprise a second SG value; and

changing said first SG value to said second SG value if said information element comprises a second SG value.

2. The method of claim 1 wherein said receiving comprises receiving said information element from a Radio Network Controller (RNC).

3. The method of claim 2 wherein said information element is received via Radio Resource Control (RRC) signaling.

4. The method of claim 1 wherein said receiving comprises receiving said information element from a Node B.

5. The method of claim 4 comprising receiving said information element via Radio Resource Control (RRC) signaling.

6. A mobile terminal comprising:

a memory for storing a first Serving Grant (SG) value when said mobile terminal is within a first serving cell;

means for receiving an information element from a higher layer during transition to a second serving cell;

means for determining if said information element comprises a second SG value;

means for maintaining said first SG value if said information element does not comprise a second SG value; and

means for changing said first SG value to said second SG value if said information element comprises a second SG value.

7. The mobile terminal of claim 6 wherein said means for receiving comprises a radio frequency transceiver, and said means for determining, said means for maintaining, and said means for changing comprise a data processor.

8. The mobile terminal of claim 6 wherein said higher layer comprises a Radio Network Controller (RNC).

9. The mobile terminal of claim 8 wherein said RNC communicates with said mobile terminal via Radio Resource Control (RRC) signaling.

10. The mobile terminal of claim 6 wherein said higher layer comprises a Node B.

11. A program of machine-readable instructions, tangibly embodied on an information bearing medium and executable by a digital data processor, to perform actions directed toward establishing a Serving Grant (SG), the actions comprising:

storing a first Serving Grant (SG) value for use in a first serving cell;

receiving an information element from a higher layer during transition to a second serving cell;

determining if said information element comprises a second SG value;

maintaining said first SG value if said information element does not comprise a second SG value; and

changing said first SG value to said second SG value if said information element comprises a second SG value.

12. The program of claim 11 wherein said receiving comprises receiving said information element from a Radio Network Controller (RNC).

13. The program of claim 12 wherein said information element is received via Radio Resource Control (RRC) signaling.

14. The program of claim 11 wherein said receiving comprises receiving said information element from a Node B.
