Abstract

A high-speed data transmission degradation method, a device, and a system, to implement, in high-speed data transmission and depending on a terminal requirement, resource degradation in which interaction load is low and a terminal remains connected to a network, so as to ensure a data transmission rate of the terminal and improve terminal user experience. The method includes receiving, by a network-side device, a degradation request sent by a terminal that is in a high-speed data transmission mode; obtaining, by the network-side device, a target to-be-degraded resource of the terminal based on the received degradation request; and degrading, by the network-side device, the target to-be-degraded resource.

First claim

What is claimed is:

1. A high-speed data transmission degradation method implemented by a network-side device, comprising:
receiving a degradation request from a terminal that is in a high-speed data transmission mode, wherein the degradation request comprises a carrier aggregation (CA) degradation parameter, and wherein the CA degradation parameter comprises an identifier of a CA component carrier and instructs the network-side device to perform CA degradation on the terminal by deactivating the CA component carrier;
determining whether the terminal is capable of proactively initiating degradation, wherein determining whether the terminal is capable of proactively initiating degradation comprises:
determining whether a 117th bit of a feature group indicator (FGI) information element in a capability indication message of the terminal is 1;
determining that the terminal is capable of proactively initiating degradation when the 117th bit of the FGI information element in the capability indication message of the terminal is 1; and
determining that the terminal is incapable of proactively initiating degradation when the 117th bit of the FGI information element in the capability indication message of the terminal is not 1;

when the terminal is capable of proactively initiating degradation, obtaining a target to-be-degraded resource of the terminal indicated by the identifier in the degradation request, wherein the target to-be-degraded resource comprises the CA component carrier that is to be deactivated when the network-side device performs CA component carrier degradation on the terminal; and
degrading the target to-be-degraded resource.

2. The high-speed data transmission degradation method of claim 1 , wherein the high-speed data transmission degradation method further comprises receiving a multiple-input multiple-output (MIMO) degradation parameter, wherein the MIMO degradation parameter instructs the network-side device to reduce a quantity of MIMO service flows of the terminal.

3. The high-speed data transmission degradation method of claim 1 , wherein the CA degradation parameter comprises a channel quality indicator (CQI) equal to negative 1.

4. The high-speed data transmission degradation method of claim 1 , wherein the degradation request is sent when the terminal detects that temperature of the terminal is greater than or equal to a preset threshold.

5. The high-speed data transmission degradation method of claim 1 , wherein the degradation request is sent when the terminal estimates that heat production of the terminal is greater than or equal to a heat withstanding capacity of the terminal.

6. The high-speed data transmission degradation method of claim 1 , wherein the degradation request is sent when radio channel quality of the terminal is less than or equal to a preset threshold.

7. A terminal, comprising:
a processor;
a transmitter coupled to the processor;
a receiver coupled to the processor; and
a memory coupled to the processor and configured to store a computer executable instruction, wherein the processor is configured to execute the computer executable instruction to configure the terminal to:
determine a target to-be-degraded resource, wherein the target to-be-degraded resource comprises a carrier aggregation (CA) component carrier of the terminal that is to be deactivated when a network-side device performs CA degradation on the terminal, wherein the terminal is capable of proactively initiating degradation, and wherein a 117th bit of a feature group indicator (FGI) information element in a capability indication message of the terminal is 1;
send a degradation request to a network-side device using the transmitter, wherein the degradation request comprises an identifier of the CA component carrier and instructs the network-side device to degrade the target to-be-degraded resource of the terminal by deactivating the CA component carrier indicated by the identifier; and
instruct the transmitter to transmit and the receiver to receive data on a resource left after degradation of the target to-be-degraded resource.

8. The terminal of claim 7 , wherein sending, by the transmitter, the degradation request to the network-side device comprises instructing, by the processor, the transmitter to send the degradation request to the network-side device when detecting that a temperature of the terminal is greater than or equal to a preset threshold.

9. The terminal of claim 7 , wherein
the processor is further configured to send to a network-side device a multiple-input multiple-output (MIMO) degradation parameter, wherein the MIMO degradation parameter instructs the network-side device to reduce a quantity of MIMO service flows of the terminal.

10. The terminal of claim 7 , wherein the degradation request comprises a CA degradation parameter comprising a channel quality indicator (CQI) equal to negative 1.

11. The terminal of claim 7 , wherein the transmitter is further configured to send a capability indication message of the terminal to the network-side device before sending the degradation request to the network-side device, and wherein the capability indication message indicates that the terminal is capable of proactively initiating degradation.

12. The terminal of claim 7 , wherein sending, by the transmitter, the degradation request to the network-side device comprises at least one of:
instructing, by the processor, the transmitter to send the degradation request to the network-side device when determining that heat production of the terminal is greater than or equal to a heat withstanding capacity of the terminal; or
instructing, by the processor, the transmitter to send the degradation request to the network-side device when determining that radio channel quality of the terminal is less than or equal to a preset threshold.

13. A network-side device, comprising:
a processor; and
a memory configured to store a computer executable instruction, wherein the processor is configured to execute the computer executable instruction to configure the network-side device to:
receive a degradation request from a terminal, wherein the degradation request comprises a carrier aggregation (CA) degradation parameter, and wherein the CA degradation parameter comprises an identifier of a CA component carrier and instructs the network-side device to perform CA degradation on the terminal by deactivating the CA component carrier;
determine whether the terminal is capable of proactively initiating degradation, wherein determining whether the terminal is capable of proactively initiating degradation comprises:
determining, by the processor, whether a 117th bit of a feature group indicator (FGI) information element in a capability indication message of the terminal is 1; and
determining that the terminal is capable of proactively initiating degradation when the 117th bit of the FGI information element in the capability indication message of the terminal is 1; and
determining that the terminal is incapable of proactively initiating degradation when the 117th bit of the FGI information element in the capability indication message of the terminal is not 1;
