Embodiment Construction

[0102] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0103] In the embodiment of the present invention, "terminal reachability" can be set as a separate service in the AMF, so as to customize the function and expand or contract the capacity of the service as required.

[0104] In order to realize flexible configuration of terminal accessible services, and further improve the flexibility of establishing a data channel for the terminal, in the embodiment of the present invention, the following solutions are proposed:

[0105] Solution 1. When downlink data arrives on the network side, but it is found that the terminal user plane data channel does not exist, related functions in the network (such as SMF (session management function, session ma...

Abstract

The invention provides a method, device and computer-readable storage medium for establishing a data channel, which relate to the technical field of communication and are used to improve the flexibility of establishing a data channel for a terminal. The method for establishing a data channel of the present invention includes: when downlink data arrives on the network side, directly calling the terminal reachable service to establish a user plane data channel for the terminal; or when downlink data arrives on the network side, indirectly calling the terminal reachable service as The terminal establishes a user plane data channel. The present invention is mainly used in the field of wireless communication.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and computer-readable storage medium for establishing a data channel. Background technique [0002] When the terminal does not transmit control signaling and user data for a period of time, the air interface resources of the terminal are released, and the user plane tunnel (base station to gateway) of the terminal is also often released. When downlink data or signaling is sent to the terminal, the network will trigger the base station to page in a certain area (such as in a TA (Tracking Area, tracking area) list). After the terminal detects the paging message, it initiates a connection establishment request and enters the connection state. [0003] The paging performed to realize the reachability of the terminal is one of the main resource-consuming functions of the core network control plane equipment in the traditional network. Furthermore, pagi...
