Abstract
Disclosed are a method for submitting data in sequence, a network device, a terminal device and a computer storage medium. The method comprises: when a bearer of data streams is transferred from a first network device to a second network device, the first network device sends first instruction information to the second network device, wherein the first instruction information is used for instructing the second network to transmit the transferred data streams on a new bearer in sequence.
Claims12
A method for delivering data in order, which is applied to a first network device, comprising:
- in a case that a bearer of a data flow is transferred from the first network device to a second network device, receiving, from a terminal device, first partial data of the data flow and a SDAP (Service Data Adaptation Protocol) end marker for indicating that the first partial data in the data flow, which have not been transmitted completely when transferring occurs, are transmitted completely;
- and
- sending the first partial data of the data flow to a core network and sending the SDAP end marker for indicating that the first partial data in the data flow, which have not been transmitted completely when the transferring occurs, are transmitted completely to the second network device;
- wherein receiving the first partial data of the data flow sent from the terminal device comprises:
- when the bearer of the data flow is transferred with a Data Radio Bearer (DRB) of the first network device continuing to be maintained, receiving a first partial Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) of the data flow, which have not been acknowledged, sent from the terminal device.

A method for delivering data in sequence, which is applied to a second network device, comprising:
- in a case that a bearer of a data flow is transferred from a first network device to the second network device, receiving a SDAP (Service Data Adaptation Protocol) end marker, sent from the first network device, for indicating that the first partial data in the data flow, which have not been transmitted completely from a terminal device to the first network device when transferring occurs, are transmitted completely;
- based on the SDAP end marker, delivering, by the second network device, second partial data of the data flow from the terminal device to a core network after the first partial data are sent to the core network;
- wherein when the bearer of the data flow is transferred with a Data Radio Bearer (DRB) of the first network device continuing to be maintained, receiving a first partial Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) of the data flow, which have not been acknowledged, sent from the terminal device.
A first network device, comprising:
- a processor, and a memory used for storing a computer program which is capable of being run on the processor, wherein the processor is configured to, when running the computer program,
- in a case that a bearer of a data flow is transferred from the first network device to a second network device, receive, from a terminal device, first partial data of the data flow and a SDAP (Service Data Adaptation Protocol) end marker for indicating that the first partial data in the data flow, which have not been transmitted completely when transferring occurs, are transmitted completely;
- and send the first partial data of the data flow to a core network and send the SDAP end marker for indicating that the first partial data in the data flow, which have not been transmitted completely when the transferring occurs, are transmitted completely to the second network device;
- wherein, the processor is configured to:
- in a case that the bearer of the data flow is transferred from the first network device to the second network device, with the Data Radio Bearer (DRB) continuing to be maintained, receive a first partial Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs) of the data flow, which have not been acknowledged, sent from the terminal device.
