Bandwidth adjustment method and terminal

A bandwidth adjustment method applicable to a receiving end, wherein the receiving end is configured to receive cells periodically sent by a sending end, and a number of the cells sent in each period is n, where n is an integer greater than or equal to 2;

• in each period, the sending end is configured to occupy a cell having a number that is carried by the cell and within a bearer cell group of the sending end, the occupied cell is capable of carrying service information, and the method comprises:
• receiving adjustment information sent by the sending end, with the adjustment information comprising an adjustment operation which is adding a cell number to be adjusted to the bearer cell group of the sending end to indicate that the sending end is to occupy a cell having a number the same as the cell number to be adjusted for carrying service information on the cell having the number the same as the cell number to be adjusted, thereby increasing a bandwidth of the sending end, or deleting the cell number to be adjusted from the bearer cell group of the sending end to indicate that the sending end is to release an occupied cell having a number the same as the cell number to be adjusted, thereby reducing a bandwidth of the sending end;
• and
• performing a preparation operation according to the adjustment information, and sending confirmation information to the sending end after the preparation operation is completed,
• wherein the confirmation information comprises:
• the cell number to be adjusted;
• and an information response value configured to indicate whether the preparation operation is completed by the receiving end, and
• wherein the preparation operation comprises:
• adding the cell number to be adjusted to the bearer cell group of the sending end, and preparing to read service information from a cell having a number the same as the cell number to be adjusted, or deleting the cell number to be adjusted from the bearer cell group of the sending end, and preparing to stop reading service information from a cell having a number the same as the cell number to be adjusted.

A terminal, wherein the terminal is configured to periodically send cells to a receiving end, a number of the cells sent in each period is n, where n is an integer greater than or equal to 2;

• in each period, the terminal is configured to occupy a cell having a number that is carried by the cell and within a bearer cell group of the terminal, the occupied cell is capable of carrying service information, and the terminal comprises a processor and a storage having instructions stored thereon which, when being executed by the processor, cause the processor to:
• send adjustment information comprising an adjustment operation to the receiving end, with the adjustment operation being adding a cell number to be adjusted to a bearer cell group of the terminal to indicate that the terminal is to occupy a cell having a number the same as the cell number to be adjusted for carrying service information on the cell having the number the same as the cell number to be adjusted, thereby increasing a bandwidth of the terminal, or deleting the cell number to be adjusted from the bearer cell group of the terminal to indicate that the terminal is to release an occupied cell having a number the same as the cell number to be adjusted, thereby reducing a bandwidth of the terminal;
• and
• receive confirmation information sent by the receiving end after a preparation operation is completed by the receiving end, and perform the adjustment operation,
• wherein the confirmation information comprises:
• the cell number to be adjusted;
• and an information response value configured to indicate whether the preparation operation is completed by the receiving end, and
• wherein the preparation operation comprises:
• adding the cell number to be adjusted to the bearer cell group of the terminal, and preparing to read service information from a cell having a number the same as the cell number to be adjusted, or deleting the cell number to be adjusted from the bearer cell group of the terminal, and preparing to stop reading service information from a cell having a number the same as the cell number to be adjusted.
