Abstract

An information control method and a communications device are provided. First time information is adjusted to second time information according to information about a clock difference between a first clock and a second clock. The first time information is time-related information based on the first clock, and the second time information is time-related information based on the second clock. First information is sent. The first information includes the first time information. The first time information includes at least one of the following: a first User Equipment (UE)-Device-Side Time-Sensitive Network Translator (Device-Side TSN Translator (DS-TT)) residence time, or a first Packet Delay Budget (PDB).

sending first information, wherein
the first information comprises at least the first time information, wherein the first time information comprises at least one of the following: a first User Equipment (UE)-Device-Side Time-Sensitive Network Translator (Device-Side TSN Translator (DS-TT)) residence time, or a first Packet Delay Budget (PDB).

2 . The first communications device according to claim 1 , wherein the first time information comprises a first delay.

3 . The first communications device according to claim 2 , wherein the first information further comprises the second time information, wherein the second time information comprises at least one of the following: a second UE-DS-TT residence time, a second PDB, or a second delay; and
the adjusting first time information to second time information comprises at least one of the following:
adjusting the first UE-DS-TT residence time to the second UE-DS-TT residence time;
adjusting the first PDB to the second PDB; or
adjusting the first delay to the second delay.

4 . The first communications device according to claim 1 , wherein the first information further comprises the clock information of the first clock or the second clock, wherein the clock information comprises at least one of the following: clock type information, time domain identifier information corresponding to a clock, or clock frequency information.

5 . The first communications device according to claim 4 , wherein the clock type information comprises at least one of the following:
