Problems solved by technology

[0004] The problem with the above implementation is: if the terminal is currently in an idle state, after receiving a paging message, it must first establish a connection with the base station through the primary carrier, and then the base station switches the terminal to the secondary carrier. In this way, the terminal can establish a connection with the base station through the secondary carrier
It can be seen that the steps for the terminal to establish a connection with the base station through the main carrier increase the air interface access delay

Embodiment Construction

[0047] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0048] An embodiment of the present invention provides a method for sending system information, such as figure 1 As shown, the method includes:

[0049] Step 101: Determine the main carrier system information;

[0050] Step 102: broadcast a first indication in the main carrier system information, and the first indication is used to inform the terminal to read the auxiliary carrier system information in a manner corresponding to the auxiliary carrier.

[0051] The embodiment of the present invention uses the primary carrier system information to instruct the terminal to read the secondary carrier system information in a manner corresponding to the secondary carrier; after receiving the instruction, the terminal can select an appropriate time to read the secondary carrier system information in combination with other factors, avoiding the The time delay impact c...

Abstract

The present invention provides a system information transmission method, a device and a computer readable storage medium, the method comprises: determining primary carrier system information; broadcasting a first indication in the primary carrier system information, wherein the first indication is used to notify a terminal to read auxiliary carrier system information according to a manner corresponding to an auxiliary carrier.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and computer-readable storage medium for sending system information. Background technique [0002] In order to ensure the low power consumption of narrowband Internet of Things (NB-IoT) terminals (subsequently referred to as terminals) and realize mobility management such as cell handover, 5G may consider combining NB-IoT carriers with enhanced machine type communication (eMTC) in the future. Carrier integration is used. The main carrier supports NB-IoT technology to meet the low power consumption requirements of NB-IoT terminals; the auxiliary carrier supports eMTC technology to meet the high speed and mobility requirements of future NB-IoT terminals. Correspondingly, the future NB-IoT terminals may be divided into two categories, one is more traditional NB-IoT terminals, oriented to extremely low speed and low cost, and can only reside and ...
