Abstract

A method for transmitting data is provided. The method includes receiving a service request for a standby subscriber terminal, such as when a call is placed to or from the standby subscriber terminal. The number of telecommunications channels carried by a trunk group is then changed, such as by increasing or decreasing the number of encoded telecommunications channels carried by the trunk group. The standby subscriber terminal is then assigned to one of the telecommunications channels of the trunk group.

Claims

1. A method for transmitting data comprising:

receiving a service request from a standby subscriber terminal;

changing the amplification power of a trunk group, said trunk group associated with at least two predetermined carrier frequencies;

changing the number of telecommunications channels for the trunk group;

assigning the standby subscriber terminal to one of the telecommunications channels of the trunk group or another trunk group;

wherein said amplification power is changed in relation to the total number of channels in the trunk group.

2. The method of claim 1, wherein changing the number of telecommunications channels for the trunk group comprises increasing the number of telecommunications channels for the trunk group.

3. The method of claim 2 wherein changing the amplification power for the trunk group comprises:

increasing the amplification power for the trunk group.

4. The method of claim 2 wherein changing the amplification power for the trunk group comprises:

decreasing the amplification power for the trunk group.

5. The method of claim 1 wherein changing the number of telecommunications channels for the trunk group comprises decreasing the number of telecommunications channels for the trunk group.

6. The method of claim 5 wherein changing the amplification power for the trunk group comprises:

decreasing the amplification power for the trunk group.

7. The method of claim 5 wherein changing the amplification power for the trunk group comprises:

increasing the amplification power for the trunk group.

8. The method of claim 1 wherein assigning the standby subscriber terminal to one of the telecommunications channels of the trunk group comprises assigning the standby subscriber terminal to one of the telecommunications channels of another trunk group, wherein changing the number of telecommunications channels for the trunk group comprises decreasing the number of telecommunications channels for the trunk group, and wherein changing the amplification power for the trunk group comprises decreasing the amplification power for the trunk group.

9. The method of claim 8 further comprising:

increasing the number of telecommunications channels for the other trunk group.

10. The method of claim 8 further comprising:

increasing the amplification power for the other trunk group.

11. The method of claim 8 further comprising:

increasing the number of telecommunications channels for the other trunk group; and

increasing the amplification power for the other trunk group.

12. A system for transmitting data comprising:

a central terminal coupled to a telecommunications network, the central terminal operable to transmit and receive data from the telecommunications network;

a plurality of subscriber terminals, each subscriber terminal operable to transmit and receive a channel of data from the central terminal;

a first trunk group having a first effective radiated power level, the first trunk group modulated by a first group of one or more data channels, wherein the first effective radiated power level may be increased or decreased as a function of the distance between a first group of one or more subscriber terminals and the central terminal, said first trunk group allocated to the central terminal; and

a second trunk group having a second effective radiated power level, the second trunk group modulated by a second group of two or more data channels, wherein the second effective radiated power level may be increased or decreased as a function of the distance between a second group of one or more subscriber terminals and the central terminal, said second trunk group allocated to the central terminal.

13. The system of claim 12 wherein the first trunk group and the second trunk group each further comprise a plurality of carriers and wherein the first trunk group is associated with a first type of service, and wherein the second trunk group is associated with a second type of service.

14. The system of claim 12 wherein the first trunk group is modulated by the first group of one or more data channels by modulating each data channel with a code division multiple access code, and the second trunk group is modulated by the second group of one or more data channels by modulating each data channel with a code division multiple access code.

15. The system of claim 12 wherein the sum of the first effective radiated power level and the second effective radiated power level are equal to or less than a predetermined value.

16. The system of claim 12 further comprising one or more additional trunk groups, each additional trunk group having an effective radiated power level, each additional trunk group modulated by an additional group of two or more data channels, wherein the effective radiated power level of each additional trunk group may be increased or decreased as a function of the distance between a second group of one or more subscriber terminals and a central terminal.

17. The system of claim 16 wherein each additional trunk group further comprises a plurality of carriers.

18. The system of claim 17 wherein the sum of each of the effective radiated power levels are equal to or less than a predetermined value.

19. A method for transmitting data comprising:

receiving a service request from a standby subscriber terminal;

changing an amplification level for a trunk group, said trunk group associated with at least two predetermined carrier frequencies;

assigning the standby subscriber terminal to a telecommunications channels of the trunk group; and

wherein the total amplification power for the trunk group is a predetermined constant.

20. The method of claim 19 wherein changing the amplification level of the trunk group comprises increasing the amplification level for the trunk group.

21. The method of claim 19 wherein changing the amplification level of the trunk group comprises decreasing the amplification level for the trunk group.
