Abstract

Embodiments of this application provide a time synchronization method and apparatus, a computer-readable medium, and an electronic device. The time synchronization method includes: receiving a triggering delivery service request message transmitted by an application function (AF) entity, the triggering delivery service request message including an identifier of a target user equipment and a time sensitive network (TSN) trigger container, the TSN trigger container being used for indicating a TSN time synchronization trigger condition; and transmitting a submission triggering message to a short message service-service center (SMS-SC), the submission triggering message being used for requesting the SMS-SC to transmit a short message including the TSN trigger container to the target user equipment, to enable the target user equipment to perform a TSN time synchronization operation based on the TSN trigger container.

Claims17

Dependent claims

A time synchronization method, comprising:

receiving a triggering delivery service request message transmitted by an application function (AF) entity, the triggering delivery service request message comprising an identifier of a target user equipment and a time sensitive network (TSN) trigger container, the TSN trigger container used to indicate a TSN time synchronization trigger condition;
converting the identifier of the target user equipment from an external identifier to a network identifier, wherein:
in response to the identifier of the target user equipment comprising an external identifier of a single user equipment, the external identifier of the single user equipment is converted into a network identifier of the single user equipment;
and in response to the identifier of the target user equipment comprising an external group identifier corresponding to a plurality of user equipments, the external group identifier is converted into a network identifier list of the plurality of user equipments;
and transmitting a submission triggering message to a short message service-service center (SMS-SC), the submission triggering message used to request the SMS-SC to transmit a short message comprising the TSN trigger container to the target user equipment, to enable the target user equipment to perform a TSN time synchronization operation based on the TSN trigger container.

A time synchronization method, comprising:

receiving a short message transmitted by a short message service-service center (SMS-SC), the short message comprising a time sensitive network (TSN) trigger container, the TSN trigger container used to indicate a TSN time synchronization trigger condition, wherein the TSN trigger container comprises second field information used to indicate an activation operation or a deactivation operation;
and
performing a TSN time synchronization operation based on information comprised in the TSN trigger container by:
in response to the second field information indicating an activation operation, and TSN activation time information comprised in the TSN trigger container instructing a user equipment to perform the TSN time synchronization operation immediately after receiving the short message, establishing a protocol data unit (PDU) session to perform the TSN time synchronization operation immediately;
in response to the second field information indicating an activation operation, and TSN activation time information comprised in the TSN trigger container instructing a user equipment to perform the TSN time synchronization operation after a predetermined time of receiving the short message, establishing a PDU session to perform the TSN time synchronization operation after the predetermined time of receiving the short message;
in response to the second field information indicating an activation operation, and TSN activation time information comprised in the TSN trigger container instructing a user equipment to perform the TSN time synchronization operation at a specified time point, establishing a PDU session to perform the TSN time synchronization operation in response to a current time reaching the specified time point;
in response to the second field information indicating an activation operation, and TSN activation time information comprised in the TSN trigger container instructing a user equipment to perform the TSN time synchronization operation at a specified time point, but a current time exceeds the specified time point, establishing a PDU session to perform the TSN time synchronization operation immediately;
and
in response to the TSN trigger container not comprising TSN activation time information, and the second field information indicating an activation operation, establishing a PDU session to perform the TSN time synchronization operation immediately.

6 more elements

A time synchronization method, comprising:

receiving a submission triggering message, the submission triggering message used to request transmission of a short message comprising a time sensitive network (TSN) trigger container to a target user equipment, the TSN trigger container used to indicate a TSN time synchronization trigger condition;
and
generating the short message, and transmitting the short message to the target user equipment, to enable the target user equipment to perform a TSN time synchronization operation based on the TSN trigger container, wherein the transmitting the short message to the target user equipment comprises:
in response to short message delivery time information comprised in the submission triggering message instructs to transmit the short message immediately or the submission triggering message does not comprise short message delivery time information, transmitting the short message to the target user equipment immediately;
in response to short message delivery time information comprised in the submission triggering message instructs to transmit the short message after a predetermined time, transmitting the short message to the target user equipment after the predetermined time of receiving the submission triggering message;
in response to short message delivery time information comprised in the submission triggering message instructs to transmit the short message at a specified time point, transmitting the short message to the target user equipment in response to a current time reaching the specified time point;
and
in response to short message delivery time information comprised in the submission triggering message instructs to transmit the short message at a specified time point, but a current time exceeds the specified time point, transmitting the short message to the target user equipment immediately.
