Abstract

Provided in the present disclosure are an information transmission method and apparatus, and a storage medium. The method comprises: sending to a second node indication information, which is used for the second node to acquire information of a terminal, wherein the information comprises information associated with a third node. In the present disclosure, when there is no network connection between a third node and a terminal, information of the terminal is forwarded to the third node, such that the reliability and availability of single-connection communication are improved, and in particular when the third node and a second node belong to different types of RATs, the reliability and availability of single-connection and cross-RAT communication are improved.

Description

TECHNICAL FIELD The present disclosure relates to the field of communication and, specifically, to an information transmission method, an apparatus and a storage medium. BACKGROUND Currently, the connection between a terminal and a network device may be either dual-connection or single-connection, where, in a dual-connection scenario, the terminal simultaneously accesses both the master node (MN) and the secondary node (SN) of the cell. In a single-connection scenario, the terminal accesses one node. Typically, for example, the terminal may access one base station at the same time and disconnect from other base stations. SUMMARY To avoid the situation where a node fails to fetch information of a terminal due to the lack of a network connection with the terminal in a single-connection scenario, embodiments of the present disclosure provide an information transmission method, an apparatus, and a storage medium. A first aspect of some embodiments of the present disclosure provides an information transmission method, which is applied to a first node, and includes: sending indication information to a second node, where the indication information is used for fetching, by the second node, of information of a terminal, and the information includes information associated with a third node. A second aspect of some embodiments of the present disclosure provides an information transmission method, which is applied to a second node, and includes: receiving indication information, where the indication information is used for fetching, by the second node, of information of a terminal, and the information includes information associated with a third node. A third aspect of some embodiments of the present disclosure provides an information transmission method, which is applied to a third node, and includes: receiving information of a terminal sent by a second node, where the second node fetches the information based on indication information, and the information includes information associated with the third node. A fourth aspect of some embodiments of the present disclosure provides a first node, which includes: a transceiver module, configured to send indication information to a second node, where the indication information is used for fetching, by the second node, of information of a terminal, and the information includes information associated with a third node. A fifth aspect of some embodiments of the present disclosure provides a second node, which includes: a transceiver module, configured to receive indication information, where the indication information is used for fetching, by the second node, of information of a terminal, and the information includes information associated with a third node. A sixth aspect of some embodiments of the present disclosure provides a third node, which includes: receiving information of a terminal sent by a second node, where the information is fetched by the second node based on indication information, and the information includes information associated with a third node. A seventh aspect of some embodiments of the present disclosure provides a first node, which includes: one or more processors;where the terminal is configured to perform the information transmission method according to any embodiment of the first aspect. An eighth aspect of some embodiments of the present disclosure provides a second node, which includes: one or more processors;where a network device is configured to perform the information transmission method according to any embodiment of the second aspect. A ninth aspect of some embodiments of the present disclosure provides a third node, which includes: one or more processors;where a network device is configured to perform the information transmission method according to any embodiment of the third aspect. A tenth aspect of some embodiments of the present disclosure provides a communication system, which includes a first node, a second node, and a third node, where the first node is configured to implement the information transmission method according to any embodiment of the first aspect, the second node is configured to implement the information transmission method according to any embodiment of the second aspect, and the third node is configured to implement the information transmission method according to any embodiment of the third aspect. An eleventh aspect of some embodiments of the present disclosure provides a storage medium, where the instruction, upon being executed on a communication device, causes the communication device to implement the information transmission method according to any embodiment of the first aspect, the second aspect, or the third aspect.
