Data control method and apparatus, communication device, and readable storage medium

A method for data control, comprising:

• receiving, by a second communication device, a data packet;
• and
• performing, by the second communication device, a second operation on the received data packet,
• wherein the second operation comprises at least one of the following:
• adding target information corresponding to a default data set to a first header of a data packet that does not conform to data characteristic information, or adding target information corresponding to a default data set to a first header of data that does not conform to any non-default data set mapping rule;
• or
• adding target information corresponding to a default data set to a first header of a data packet that does not conform to data characteristic information in any non-default data set mapping rule,
• wherein the target information comprises at least one of the following:
• first information or index information used to indicate a value of the first information;
• and
• the first information comprises at least one of the following:
• data description information of a data packet;
• data tunnel association information;
• data set association information;
• or
• first operation indication information.

An electronic device, comprising:

• a memory storing a computer program;
• and a processor coupled to the memory and configured to execute the computer program to perform operations comprising:
• obtaining first information or index information used to indicate a value of the first information;
• and
• performing a quality of service (QoS) control operation according to the first information or the index information used to indicate the value of the first information,
• wherein the first information comprises:
• data tunnel association information,
• wherein the QoS control operation comprises:
• performing a coordinated scheduling operation on data packets in data tunnels having an association relationship, wherein in the coordinated scheduling operation, synchronous scheduling is performed on the data packets that are mapped to different data tunnels.
