Abstract
This disclosure provides methods, apparatuses, and a system for implementing service continuity in a data flow switch procedure. One example method includes that indication information is used to indicate a data flow for which an end marker message is used. In the data flow switch procedure, after receiving the end marker message, a source access network device can correctly identify, based on the indication information, the data flow on which the end marker message works, and can perform different processing on a data flow switched to a target access network device and a data flow kept on the source access network device.
Claims17
A data processing method, comprising:
- sending, by a first access network device, indication information to a first core network element, wherein the indication information indicates a first data flow that is in a first session and that is to-be-switched, and the indication information comprises information for triggering to send an end marker message;
- receiving, by the first access network device, an end marker message from a second core network element, wherein the end marker message indicates that the end marker message works on a switched data flow in the first session;
- determining, by the first access network device based on the first data flow, that the end marker message works on the first data flow;
- and
- when the first access network device receives a second data packet of a second data flow in the first session after receiving the end marker message, sending, by the first access network device, the second data packet to a terminal device, wherein
- the second data flow is a data flow kept on the first access network device;
- wherein the first core network element is a session management function network element, and the second core network element is a user plane function network element.
A communication apparatus, comprising at least one transceiver and at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
- sending indication information to a first core network element, wherein the indication information indicates a first data flow that is in a first session and that is to-be-switched, and the indication information comprises information for triggering to send an end marker message;
- receiving an end marker message from a second core network element, wherein the end marker message indicates that the end marker message works on a switched data flow in the first session;
- determining based on the first data flow, that the end marker message works on the first data flow;
- and
- sending a second data packet of a second data flow in the first session received after the end marker message to a terminal device, wherein the second data flow is a data flow kept on the communication apparatus;
- wherein the first core network element is a session management function network element, and the second core network element is a user plane function network element.
A non-transitory computer-readable storage medium storing one or more programming instructions executable by at least one processor to cause the at least one processor to execute:
- sending indication information to a first core network element, wherein the indication information indicates a first data flow that is in a first session and that is to-be-switched, and the indication information comprises information for triggering to send an end marker message;
- receiving an end marker message from a second core network element, wherein the end marker message indicates that the end marker message works on a switched data flow in the first session;
- determining based on the first data flow, that the end marker message works on the first data flow;
- and
- sending a second data packet of a second data flow in the first session received after the end marker message to a terminal device, wherein the second data flow is a data flow kept on a first access network device;
- wherein the first core network element is a session management function network element, and the second core network element is a user plane function network element.
