Abstract

The present invention discloses a method, a device, and a system for synchronizing a physical layer state, and belongs to the field of communications technologies. The present invention realizes synchronization of the physical layer state of the first feature at the network side and the terminal after the terminal updates the RRC layer configuration corresponding to the first feature.

First claim

What is claimed is:

1. A method for controlling a physical layer state, comprising:
receiving, by a base station, indication information sent from a radio network controller (RNC), wherein the indication information is sent by the RNC according to capability information of a terminal and access layer version information of the terminal, wherein the capability information of the terminal and the access layer version information of the terminal are sent by the terminal to the RNC, and the capability information of the terminal is that the terminal is supporting a dual-cell high speed downlink packet access (DC-HSDPA) feature; and
sending, by the base station according to the indication information, a high speed shared control channel (HS-SCCH) order to the terminal for controlling a DC-HSDPA physical layer state of the terminal if the access layer version information of the terminal is a universal mobile telecommunications system (UMTS) release 9 (R9) or a universal mobile telecommunications system (UMTS) version later than UMTS R9; or
not sending, by the base station according to the indication information, a high speed shared control channel (HS-SCCH) order to the terminal for controlling a DC-HSDPA physical layer state of the terminal if the access layer version information of the terminal is a universal mobile telecommunications system (UMTS) release 8 (R8) or a universal mobile telecommunications system (UMTS) version earlier than UMTS R8.

2. The method of claim 1 , wherein before the base station sends or does not send the HS-SCCH order, configuration at a radio resource control (RRC) layer corresponding to the DC-HSDPA feature is updated by the terminal.

3. The method of claim 1 , wherein the controlling the DC-HSDPA physical layer state of the terminal comprises:
activating or deactivating the DC-HSDPA physical layer state of the terminal.

4. An apparatus, comprising:
a receiver, configured to receive indication information sent from a radio network controller (RNC), wherein the indication information is sent by the RNC according to capability information of a terminal and access layer version information of the terminal, wherein the capability information of the terminal and the access layer version information of the terminal are sent by the terminal to the RNC, and the capability information of the terminal is that the terminal is supporting a dual-cell high speed downlink packet access (DC-HSDPA) feature; and
a transmitter, configured to, if the access layer version information of the terminal is a universal mobile telecommunications system (UMTS) release 9 (R9) or a universal mobile telecommunications system (UMTS) version later than UMTS R9, send according to the indication information a high speed shared control channel (HS-SCCH) order to the terminal for controlling a DC-HSDPA physical layer state of the terminal; or, if the access layer version information of the terminal is a universal mobile telecommunications system (UMTS) release 8 (R8) or a universal mobile telecommunications system (UMTS) version earlier than UMTS R8, not send according to the indication information a high speed shared control channel (HS-SCCH) order to the terminal for controlling a DC-HSDPA physical layer state of the terminal.

5. The apparatus of claim 4 , wherein after the terminal updates configuration at a radio resource control (RRC) layer corresponding to the DC-HSDPA feature, the transmitter is configured to send or not send the HS-SCCH order.

6. The apparatus of claim 4 , wherein the controlling the DC-HSDPA physical layer state of the terminal comprises: activating or deactivating the DC-HSDPA physical layer state of the terminal.

7. A method for controlling a physical layer state, comprising:
sending, by a terminal, capability information about the terminal supporting a dual-cell high speed downlink packet access (DC-HSDPA) feature and access layer version information of the terminal to a radio network controller (RNC);
receiving, by the terminal, a high speed shared control channel (HS-SCCH) order from a base station when the base station receives indication information from the RNC, wherein the indication information is used for indicating the base station to send the HS-SCCH order if the access layer version information of the terminal is a universal mobile telecommunications system (UMTS) release 9 (R9) or a universal mobile telecommunications system (UMTS) version later than UMTS R9; and
controlling, by the terminal, a DC-HSDPA physical layer state of the terminal according to the HS-SCCH order.

8. The method of claim 7 , wherein before receiving the HS-SCCH order, the method further comprises:
updating, by the terminal, configuration at a radio resource control (RRC) layer corresponding to the DC-HSDPA feature.

9. The method of claim 7 , wherein the controlling the DC-HSDPA physical layer state of the terminal comprises:
activating or deactivating the DC-HSDPA physical layer state of the terminal.

10. An apparatus, comprising:
a transmitter, configured to send capability information about the terminal supporting a dual-cell high speed downlink packet access (DC-HSDPA) feature and access layer version information of the terminal to a radio network controller (RNC);
a receiver, configured to receive a high speed shared control channel (HS-SCCH) order from a base station when the base station receives indication information from the RNC, wherein the indication information is used for indicating the base station to send the HS-SCCH order if the access layer version information of the terminal is a universal mobile telecommunications system (UMTS) release 9 (R9) or a universal mobile telecommunications system (UMTS) version later than UMTS R9; and
a processor, configured to control a DC-HSDPA physical layer state of the terminal according to the HS-SCCH order.

11. The apparatus of claim 10 , wherein the processor is further to update, before the receiver receives the HS-SCCH order, configuration at a radio resource control (RRC) layer corresponding to the DC-HSDPA feature.

12. The apparatus of claim 10 , wherein the processor is configured to control the DC-HSDPA physical layer state of the terminal implemented by activating or deactivating the DC-HSDPA physical layer state of the terminal.

13. A method for controlling a physical layer state, comprising:
receiving, by a radio network controller (RNC), capability information about the terminal supporting a dual-cell high speed downlink packet access (DC-HSDPA) feature and access layer version information of the terminal from a terminal; and
sending, by the RNC according to the access layer version information of the terminal, indication information to a base station;
wherein the indication information is used to indicate the base station to send, if the access layer version information of the terminal is a universal mobile telecommunications system (UMTS) release 9 (R9) or a universal mobile telecommunications system (UMTS) version later than UMTS R9, a high speed shared control channel (HS-SCCH) order to the terminal for controlling a DC-HSDPA physical layer state of the terminal; or, the indication information is used to indicate the base station to not send, if the access layer version information of the terminal is a universal mobile telecommunications system (UMTS) release 8 (R8) or a universal mobile telecommunications system (UMTS) version earlier than UMTS R8, a high speed shared control channel (HS-SCCH) order to the terminal for controlling a DC-HSDPA physical layer state of the terminal.
