Problems solved by technology

[0003] When the number of terminals in a group is large, the existing group access communication system cannot all compete in time to successfully obtain channel access, and still cannot meet the low-latency requirements of large-scale terminal application scenarios.

Embodiment approach 1

[0048] Implementation Mode 1: Divide large-scale terminals into several groups, and the terminals in each group establish circles of friends with related terminals, and terminals that fail to compete for channels use the channels successfully obtained by terminals in their circles of friends. Competing for the channel within the time period. The flowchart of this embodiment is as follows figure 2 shown.

Embodiment approach 2

[0049] Implementation Mode 2: Divide large-scale terminals into several groups, and the terminals in each group compete for channels within a set period of time. The terminal competes for the successfully obtained channel. The flowchart of this embodiment is as follows image 3 shown.

[0050] In a preferred implementation manner, the large-scale terminals are divided into several groups, including steps:

[0051] Calculate the number of groups according to the total number of large-scale terminals and the correlation value between terminals;

[0052] Group large-scale terminals based on the association between terminals and the number of groups.

[0053]The total number of smart terminals is recorded as n, and the correlation value between terminals is set in advance or calculated according to the distance, signal strength, propagation delay, characteristic parameters, etc. of the terminals in the group (not expanded here, see the following implementation for details Exam...

Abstract

The invention discloses a large-scale terminal access method and system. The method comprises the following steps: dividing large-scale terminals into a plurality of groups, enabling the terminals ineach group to compete for a channel in a set time period, enabling the terminals in each group to establish a friend circle with related terminals, and enabling the terminals with failed channel competition to compete for the successfully obtained channel by using the terminals in the friend circle. According to the method and the system, the technical problem that the existing packet access communication system cannot meet the requirement of a large-scale terminal application scene on low time delay is solved.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a large-scale terminal access method and system. Background technique [0002] The current NB-IoT-based smart terminal applications are gradually mature. Large-scale terminals access the network through a base station at the same time. The polling access algorithm is stable but requires high synchronization and prolongs the time. The high collision rate of the contention access algorithm results in protracted time. . An effective solution is to use packet access communication. The existing packet communication system, such as the Chinese patent "System for Sending Packet Data in Wireless Telephone TDMA System" with the publication number CN1115164A, proposes a method for sending packet data in a cellular system , the number of time slots in a TDMA frame designated for packet transmission varies according to the needs of transmission, and each logical channel con...
