Problems solved by technology

[0009] Disadvantages of the existing technology: when the PRACH channel is congested, the fallback access time interval T is a cell-level parameter, which cannot distinguish between different services or different user settings
After the initial access failure of multiple users, random access attempts will be initiated again. Although multiple users choose a random time within (0, T) to try again, because each cell can only be set to one T value , when multiple users try to access again, there is still a high probability of access failure

Embodiment Construction

[0029] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] This embodiment first provides a network architecture, figure 2 It is a schematic diagram of the composition structure of the network architecture of the embodiment of the present invention, such as figure 2 As shown, the data synchronization architecture includes two or more terminals 11 to 1N and a base station 31 , wherein the terminals 11 to 1N interact with the base station 31 through the network 21 . The implementation of the terminal is related to the field where the Internet of Things (IOT) is located. Generally speaking, the terminal can be various types of equipment with information processing capabilities during the implementation process. For example, the terminal can include mobile sales Point Of Sale (POS) machines, personal bicycles, smart light poles, meter reading terminals, sensor devices,...

Abstract

The embodiment of the invention discloses a method and a device for determining fallback time, equipment and a storage medium, and the method comprises the steps: enabling a base station to determinethe service type of a terminal when a physical random access channel is congested; determining a fallback access time interval or fallback time corresponding to the terminal by the base station according to the service type of the terminal; and sending the time interval or the fallback time of the fallback access to the terminal by the base station.

Description

technical field [0001] The present invention relates to the Internet of Things technology, and in particular to a method, device, device, and storage medium for determining rollback time. Background technique [0002] In the application of the cellular Internet of Things, there are scenarios where a large number of users access the network concurrently, such as smart meter reading, smart light poles and other services, and there are situations where a large number of terminals report data to the network at the same or similar time. At the same time, in the process of accessing the network, network congestion is very likely to occur, causing many users to fail to access. [0003] In the existing solution, the process of terminal accessing the network figure 1 shown. When multiple terminals access the network at the same time: [0004] Step 1: The terminal (User Equipment, UE) sends a random access preamble (Preamble) code in the uplink narrowband physical random access cha...
