Abstract

An access burst and normal burst mix-mode support for GSM/GPRS compliant handsets is provided and may comprise transmitting bursts of different data types within a single GSM frame by a single GSM device, wherein the data types may comprise access burst and normal burst. Transmit power may be ramped up prior to transmitting a first burst in the GSM frame for the single GSM device, and ramped down after transmitting a first burst in the GSM frame for the single GSM device. A plurality of ramp-up and ramp-down values may be stored for use in ramping up or ramping down the transmit power, respectively. The plurality of ramp-up and ramp-down values may be converted to an analog control signal that may be used to control the ramping up and ramping down of the transmit power, respectively.

Claims

1. A method for transmitting data, the method comprising transmitting bursts of different data types within a single GSM frame by a single GSM device, wherein said different data types comprise access burst data type and normal burst data type.

2. The method according to claim 1, further comprising ramping up transmit power prior to said transmitting a first burst in said GSM frame by said single GSM device.

3. The method according to claim 2, further comprising storing a plurality of ramp-up values for use in said ramping up transmit power.

4. The method according to claim 3, further comprising converting said plurality of ramp-up values to an analog control signal to control said ramping up transmit power.

5. The method according to claim 1, further comprising ramping down transmit power after said transmitting a last burst in said GSM frame for said single GSM device.

6. The method according to claim 5, further comprising storing a plurality of ramp-down values for use in said ramping down transmit power.

7. The method according to claim 6, further comprising converting said plurality of ramp-down values to an analog control signal to control said ramping down transmit power.

8. The method according to claim 1, further comprising storing data in memory to be transmitted within said single GSM frame by a single GSM device.

9. The method according to claim 8, further comprising selecting at least a portion of said stored data for initialization portion of said bursts.

10. The method according to claim 8, further comprising selecting at least a portion of said stored data for data portion of said bursts.
