Method and Device for Controlling Combined UMTS/GSM/EDGE Radio Systems

A method, comprising:

• providing first and second signals based respectively upon first and second radio standards to a radio station having first and second systems,
• processing the first signals in a first system, generating a first synchronization signal and providing it to the second system;
• processing the second signals in a second system, generating a second synchronization signal and providing it to the first system;
• and
• storing suitable second system information in the first system upon receipt of the second synchronization signal and storing suitable first system information in the second system upon receipt of the first synchronization signal.

A method of providing sequence control of a UMTS system and a GSM system in a combined UMTS/GSM mobile station, comprising:

• receiving UMTS/GSM signals based respectively upon UMTS and GSM standards to a station having UMTS and second systems;
• processing the UMTS signals in a UMTS system, generating a UMTS synchronization signal and providing it to the GSM system;
• processing the second signals in a GSM system, generating a GSM synchronization signal and providing it to the UMTS system;
• storing suitable GSM system information in the UMTS system upon receipt of the GSM synchronization signal and storing suitable UMTS system information in the GSM system upon receipt of the UMTS synchronization signal;
• and
• utilizing the stored GSM system information from the UMTS system and the stored UMTS information from the GSM system to inhibit the UMTS and GSM from transmitting at the same time.

A radio station to process signals based upon first and second radio standards, comprising:

• a first system to receive a first signal based upon the first radio standard and generate a first synchronization signal for the second system;
• the second system to receive a second signal based upon the second radio standard and generate a second synchronization signal for the first system;
• and
• a control unit to store second system information in the first system in accordance with the second synchronization signal and to store first system information in the second system in accordance with the first synchronization signal.

A station to process signals based upon first and second radio standards, comprising:

• a first system to receive a first signal based upon the first standard and generate a first synchronization signal for a second system;
• the second system to receive a second signal based upon the second standard and generate a second synchronization signal for the first system;
• and
• a synchronous serial connection coupled to store second system information in the first system in accordance with the second synchronization signal and to store first system information in the second system in accordance with the first synchronization signal, and
• a time control unit in one of the first and second systems to receive system information from the other of the first and second systems to avoid transmission in that one of the first and second system during transmission in the other of the first and second systems.
