The disclosure describes a method and system for dynamically adjusting the output power level in each channel of a multichannel mobile cellular to satellite telecommunication system, the power levels of the voice and data channels being preset to appropriate initial output power levels, the initial power level for data channels being higher than the initial power level for voice channels. The method includes receiving a call request from communication equipment on one of the plurality of channels; determining whether the call is a voice call or a data call, determining whether a transmission channel is available for the call; assigning the call to an available voice or data transmission channel; looking up pre-stored power parameters for each active transmission channel; transmitting the parameters to each active transmission channel via a message; and dynamically adjusting the output power of each active transmission channel in response to the transmitted parameters.

The method of claim 4, wherein the first communication network is an ANSI-41 cellular network. 6. The method of claim 4, wherein the second communication network is a GSM cellular network. 7. The method of claim 4, further comprising: receiving a redirection request acknowledgement message from the first communication network in response to sending the redirection request; sending a resume call forwarding acknowledgement message to the second communication network in response to receiving the redirection request acknowledgement message; and releasing a connection between the first communication network and the second communication network. 8. The method of claim 4, wherein performing call forwarding includes: receiving a routing request from the first communication network having a call forwarding number; sending a provide roaming number message to a visitor location register of the second communication network; receiving a roaming number acknowledgement message from the visitor location register, the roaming number acknowledgement message including a roaming number of the call forwarding number; and sending the roaming number to the first communication network. 9. The method of claim 8, wherein the roaming number is converted from a first format used by the second communication network into a second format used by the first communication network. 10. The method of claim 9, wherein the roaming number in the first format is a mobile subscriber routing number and the roaming number in the second format is a temporary location directory number. 11. A communication system, comprising: a first communication network; a second communication network; and an interworking/interoperability unit coupled to the first communication network and the second communication network, wherein the interworking/interoperability unit receives a resume call forwarding message from the second communication network, sends a redirection request message to the first communication network in response to receiving the resume call forwarding message, receives a call forwarding number in response to sending the redirect request, and performs call forwarding based on the call forwarding number. 12. The system of claim 11, wherein the first communication network is an ANSI-41 cellular network. 13. The system of claim 11, wherein the second communication network is a GSM cellular network. 14. The system of claim 11, wherein the interworking/interoperability unit receives a redirection request acknowledgement message from the first communication network in response to sending the redirection request, sends a resume call forwarding acknowledgement message to the second communication network in response to receiving the redirection request acknowledgement message, and releases a connection between the first communication network and the second communication network. 15. The system of claim 11, wherein the interworking/interoperability unit performs call forwarding by receiving a routing request from the first communication network having a call forwarding number, sending a provide roaming number message to a visitor location register of the second communication network, receiving a roaming number acknowledgement message from the visitor location register, the roaming number acknowledgement message including a roaming number of the call forwarding number, and sending the roaming number to the first communication network for use in establishing a connection to a communication device associated with the call forwarding number. 16. The system of claim 15, wher
