Abstract

A data processing method, a terminal-side device and a network-side device are provided. The data processing method applied to a terminal-side device includes: obtaining configuration information, wherein the configuration information is used for indicating that information is to be reported when a secondary cell failure occurs; when a secondary cell failure occurs in a radio bearer of the terminal-side device, reporting relevant information of the secondary cell failure to a network-side device. The method further includes processing a bearer and a cell corresponding to a Radio Link Control (RLC) entity to which the secondary cell failure occurs.

First claim

What is claimed is:

1. A data processing method, applied to a terminal-side device, the method comprising:
obtaining configuration information, wherein the configuration information is used for indicating that information is to be reported when a secondary cell failure occurs;
when the secondary cell failure occurs in a radio bearer of the terminal-side device, reporting relevant information of the secondary cell failure to a network-side device;
wherein reporting the relevant information of the secondary cell failure to the network-side device comprises:
directly reporting the relevant information of the secondary cell failure to a Secondary Node (SN) through a Signaling Radio Bearer 3 (SRB3) of a Secondary Cell Group (SCG), in case the secondary cell failure occurs in the SCG; or
reporting the relevant information of the secondary cell failure to a Master Node (MN) through a Signaling Radio Bearer 1 (SRB1) of a Master Cell Group (MCG) so that the MN sends the relevant information of the secondary cell failure to a Secondary Node (SN), in case the secondary cell failure occurs in the MCG;
the relevant information of the secondary cell failure comprises,
a cell group identifier of a cell group in which the secondary cell failure occurs and a logical channel identifier corresponding to a Radio Link Control (RLC) entity to which the secondary cell failure occurs.

2. The method according to claim 1 , further comprising:
processing a bearer and a cell corresponding to a Radio Link Control (RLC) entity to which the secondary cell failure occurs.

3. The method according to claim 1 , wherein the configuration information is information, configured by the network-side device or agreed by a communication protocol, about whether information is to be reported when the secondary cell failure occurs.

4. The method according to claim 1 , wherein the radio bearer to which the secondary cell failure occurs, comprises at least one of a Signaling Radio Bearer (SRB) or a Data Radio Bearer (DRB).

5. The method according to claim 4 , wherein the Signaling Radio Bearer (SRB), to which the secondary cell failure occurs, of the terminal-side device is a Signaling Radio Bearer (SRB), to which the secondary cell failure occurs, in a Master Cell Group (MCG) of the terminal-side device;
processing the bearer and the cell corresponding to the Radio Link Control (RLC) entity to which the secondary cell failure occurs comprises one or more of following:
re-establishing a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
re-establishing a Radio Link Control (RLC) entity corresponding to a secondary cell corresponding to an RLC entity to which a secondary cell failure occurs;
deactivating a secondary cell corresponding to a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
stopping uplink signal transmission in a secondary cell corresponding to a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
stopping downlink signal reception in a secondary cell corresponding to a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
deactivating a Packet Data Convergence Protocol (PDCP) data duplication function;
if a default transmission path of a Signaling Radio Bearer (SRB) configured with a Packet Data Convergence Protocol (PDCP) data duplication function is a transmission path corresponding to a Radio Link Control (RLC) entity to which a secondary cell failure occurs, modifying the default transmission path as a transmission path corresponding to a Radio Link Control (RLC) entity to which a secondary cell failure has not occurred;
if all Radio Link Control (RLC) entities of a Signaling Radio Bearer (SRB) configured with a Packet Data Convergence Protocol (PDCP) data duplication function fail, and all of the Radio Link Control (RLC) entities are configured to transmit on the secondary cell, then suspending a bearer configured with the PDCP data duplication function;
if all Radio Link Control (RLC) entities of a Signaling Radio Bearer (SRB) configured with a Packet Data Convergence Protocol (PDCP) data duplication function fail, and all of the Radio Link Control (RLC) entities are configured to transmit on a secondary cell, then re-establishing a PDCP entity corresponding to a bearer configured with the PDCP data duplication function;
if all Radio Link Control (RLC) entities of a Signaling Radio Bearer (SRB) configured with a Packet Data Convergence Protocol (PDCP) data duplication function fail, and all of the Radio Link Control (RLC) entities are configured to transmit on a secondary cell, then resetting a Media Access Control (MAC) entity corresponding to a bearer configured with the PDCP data duplication function;
if all Radio Link Control (RLC) entities of a Signaling Radio Bearer (SRB) configured with a Packet Data Convergence Protocol (PDCP) data duplication function fail, and all of the Radio Link Control (RLC) entities are configured to transmit on a secondary cell, then triggering a Radio Resource Control (RRC) connection re-establishment process;
suspending a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
re-establishing a Radio Link Control (RLC) entity to which a secondary cell failure occurs, and suspending the Radio Link Control (RLC) entity;
suspending a Signaling Radio Bearer (SRB) to which a secondary cell failure occurs;
re-establishing a Signaling Radio Bearer (SRB) to which a secondary cell failure occurs, and, suspending the Signaling Radio Bearer (SRB);
stopping data transmission or data reception of a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
releasing or deleting a Radio Link Control (RLC) entity to which a secondary cell failure occurs.

6. The method according to claim 5 , wherein a type of a Signaling Radio Bearer (SRB) to which a secondary cell failure occurs comprises one or more of SRB0, SRB1, and SRB2.

7. The method according to claim 4 , wherein the Signaling Radio Bearer (SRB), to which the secondary cell failure occurs, of the terminal-side device is a Signaling Radio Bearer (SRB), to which the secondary cell failure occurs, in a Secondary Cell Group (SCG) of the terminal-side device,
processing the bearer and the cell corresponding to the Radio Link Control (RLC) entity to which the secondary cell failure occurs, comprises one or more of following:
re-establishing a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
re-establishing a Radio Link Control (RLC) entity corresponding to a secondary cell corresponding to an RLC entity to which a secondary cell failure occurs;
deactivating a secondary cell corresponding to a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
stopping uplink signal transmission in a secondary cell corresponding to a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
stopping downlink signal reception in a secondary cell corresponding to a Radio Link Control (RLC) entity to which a secondary cell failure occurs;
