Method and device for controlling combined UMTS/GSM/EDGE radio systems
In a method for controlling radio systems designed for transmission/reception of signals based on at least two radio standards with different time patterns, with signals based on one of these radio standards being processed in each radio system, at least one synchronization signal is produced in the first and/or second radio system for synchronization, respectively, is transmitted to the respective other radio system and system information associated with that particular radio system is in each case stored in that radio system to which the synchronization signal is transmitted. The stored system information can be read by the respective other radio system via an interface, and times for transmission of signals can be calculated by means of the information which has been read. The transmission of signals or the production of events in a radio system can be enabled or inhibited by means of a signal from the other radio systems.
1. 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 from the processed first signal and providing it to the second system;
processing the second signals in a second system, generating a second synchronization signal from the processed second 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.
2. 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 from the processed UMTS signal and providing it to the GSM system;
processing the second signals in a GSM system, generating a GSM synchronization signal from the processed GSM 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.
3. A radio station configured to process signals based upon first and second radio standards, comprising:
a first system configured to receive a first signal based upon the first radio standard, and to generate a first synchronization signal for a second system, the first synchronization signal being based on the first signal;
the second system configured to receive a second signal based upon the second radio Standard, and to generate a second synchronization signal for the first system, the second synchronization signal being based on the second signal; and
a control unit configured to store second system information in the first system in accordance with the second synchronization signals, and further configured to store first system information in the second system in accordance with the first synchronization signal.
4. A station configured to process signals based upon first and second radio standards, comprising:
a first system configured to receive a first signal based upon the first standard, and to generate a first synchronization signal for a second system, the first synchronization signal being based on the first signal;
the second system configured to receive a second signal based upon the second standard, and to generate a second synchronization signal for the first system, the second synchronization signal being based on the second signal; 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,
wherein one of the first and second systems comprises a time control unit, and wherein the time control unit is configured 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.
