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.
Claims15
A method for synchronizing a physical layer state, comprising:
- receiving relevant information about a first feature reported by a terminal;
- judging whether the terminal has a specified state at a physical layer after configuration at a radio resource control (RRC) layer corresponding to the first feature is updated according to the relevant information about the first feature;
- notifying a base station to control, according to whether the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated, the physical layer state of the first feature after re-configuration;
- or, notifying the base station of whether to control the physical layer state of the first feature according to whether the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated;
- judging a version of the terminal and judging whether the terminal has a capability of supporting the first feature according to access layer version information of the terminal in the relevant information about the first feature and further according to capability information about the first feature;
- determining that the terminal has no specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated when the version of the terminal is a first version and the terminal has the capability of supporting the first feature;
- and
- determining that the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated when the version of the terminal is a second version and the terminal has the capability of supporting the first feature;
- wherein the first version is one of universal mobile telecommunications system (UMTS) release 8 (R8) or a UMTS version earlier than UMTS R8, and wherein the second version is one of UMTS release 9 (R9) or a UMTS version later than UMTS R9.

A serving radio network controller (SRNC), comprising:
- a receiver, configured to receive relevant information about a first feature reported by a terminal;
- a processor coupled to the receiver and configured to judge whether the terminal has a specified state at a physical layer after configuration at a radio resource control (RRC) layer corresponding to the first feature is updated according to the relevant information about the first feature;
- and
- a transmitter coupled to the processor and configured to notify a base station to control a physical layer state of the first feature after re-configuration according to whether the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated;
- or, notify the base station of whether to control the physical layer state of the first feature according to whether the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated;
- wherein the processor is further configured to judge a version of the terminal and judge whether the terminal has a capability of supporting the first feature according to access layer version information of the terminal in the relevant information about the first feature and further according to capability information about the first feature;
- and
- wherein the processor is further configured to perform at least one of determine that the terminal has no specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated when the version of the terminal is a first version and the terminal has the capability of supporting the first feature, or, determine that the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated when the version of the terminal is a second version and the terminal has the capability of supporting the first feature;
- wherein the first version is one of universal mobile telecommunications system (UMTS) release 8 (R8) or a UTMS version earlier than UMTS R8, and wherein the second version is one of UMTS release 9 (R9) or a UTMS version later than UMTS R9.
