Embodiment Construction

[0050] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction of related technologies of the present application is given as follows.

[0051] First, the MLAN identification (identity, ID):

[0052] The MLAN identifier is used to identify an MLAN instance, that is, a group of logical devices and users. If MLAN is divided according to scenarios, such as enterprise class, vehicle to everything communication (V2X), a type of MLAN scenario can be identified by an MLAN type or a data network name (Data network name, DNN), that is, a The MLAN identifier consists of a scene identifier + MLAN number. Combining the scene identifier and the MLAN number can uniquely identify a certain MLAN instance in a class of MLAN scenarios. If DNN resources are sufficient, MLAN does not need to be divided according to scenarios, and an MLAN identifier corresponds to a unique MLAN instance under a DNN. The following embodim...

Abstract

The embodiment of the invention provides a data transmission method, device and system. The transmission bandwidth can be saved in an MLAN multicast scene. The method comprises the steps that a user plane functional entity receives a data packet from a source device, and the data packet carries multicast information; the user plane functional entity determines path downlink information of n multicast paths corresponding to the target mobile local area network MLAN; And the user plane functional entity sends the data packet to the corresponding n access devices through the n multicast paths corresponding to the path downlink information of the n multicast paths, wherein n is a positive integer.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data transmission method, device and system. Background technique [0002] A local area network (LAN) is a computer communication network that connects various computers, external devices, and databases within a local geographical area, such as a school, factory, and institution. It can be connected with a remote local area network, database or processing center through a data communication network or a dedicated data circuit to form a large-scale information processing system. With the emergence of emerging enterprise office models and smart home models, wired LAN and wireless LAN (wireless LAN, WLAN) have shown their deficiencies in deployment complexity, flexibility, mobility, coverage, etc., which prompts the further development of LAN technology In order to meet the needs of future applications on the LAN. [0003] Using the wide coverage feature of t...
