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 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.

2. The method according to claim 1 , further comprising:
notifying the base station to ensure that the physical layer state of the first feature after re-configuration is the same as the specified state when the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated; and
notifying the base station to send, after the terminal updates the configuration at the RRC layer corresponding to the first feature, a high speed shared control channel (HS-SCCH) order to synchronize with the physical layer state of the first feature of the terminal when the terminal has no specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated.

3. The method according to claim 1 , further comprising any one of the following steps:
Step A: sending a first message to the base station to notify the base station to ensure that the physical layer state of the first feature after re-configuration is the same as the specified state when the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated;
Step B: not sending the first message to the base station, and notifying the base station to send, after the terminal updates the configuration at the RRC layer corresponding to the first feature, a high speed shared control channel (HS-SCCH) order to synchronize with the physical layer state of the first feature of the terminal when the terminal has no specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated;
Step C: not sending the first message to the base station, and notifying the base station to ensure that the physical layer state of the first feature after re-configuration is the same as the specified state when the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated;
Step D: sending a second message to the base station to notify the base station to send, after the terminal updates the configuration at the RRC layer corresponding to the first feature, the high speed shared control channel (HS-SCCH) order to synchronize with the physical layer state of the first feature of the terminal when the terminal has no specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated;
Step E: sending the first message to the base station to notify the base station to ensure that the physical layer state of the first feature after re-configuration is the same as the specified state when the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated; and
Step F: sending the second message to the base station to notify the base station to send, after the terminal updates the configuration at the RRC layer corresponding to the first feature, the high speed shared control channel (HS-SCCH) order to synchronize with the physical layer state of the first feature of the terminal when the terminal has no specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated.

4. The method according to claim 3 , wherein the sending the first or second message to the base station comprises one of the following steps:
Step 1: sending the first or second message, respectively, to the base station through an Iub interface; and
Step 2: sending the first or second message, respectively, to a drift radio network controller (DRNC) through an Iur interface, so that the DRNC forwards the first or second message, respectively, to the base station.

5. The method according to claim 3 , wherein the first and second messages comprise a signaling and frame protocol (FP) data frame.

6. The method according to claim 1 , further comprising:
notifying the base station to send a high speed shared control channel (HS-SCCH) order to control the physical layer state of the first feature when the terminal has the specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated; and
notifying the base station not to send the high speed shared control channel (HS-SCCH) order to control the physical layer state of the first feature when the terminal has no specified state at the physical layer after the configuration at the RRC layer corresponding to the first feature is updated.

7. The method according to claim 1 , wherein the first feature comprises any one of a discontinuous transmission (DTX) feature, a discontinuous reception (DRX) feature, a high speed shared control channel (HS-SCCH) less feature, and a dual-cell high speed uplink packet access (DC-HSUPA) feature.

8. 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
