Problems solved by technology

On the one hand, because only some of the fields in MIB and SIB1 are frequently changed, while the rest of the fields are relatively stable, the terminal device re-reads all the contents in MIB and SIB1 every time, and the work efficiency is low.
On the other hand, due to the narrowband technology used in NB-IoT, the time delay for terminal devices to read system messages is large, resulting in high power consumption and high cost.
It can be seen that there is room for optimization and needs in the change process of the existing system messages of NB-IoT

Abstract

The embodiment of the present application discloses a system message indicating method, device and system, which relate to the field of communication technology and are used to reduce the time delay for terminal equipment to update the system message and reduce power consumption. The method includes: the network device generates notification information, the notification information is used to indicate the state information of the first information, the first information includes at least one bit in the first system message, and the number of bits contained in the first information is smaller than the number of bits in the first system message The number of bits included; the network device sends the notification information to the terminal device. The embodiment of the present application is applied in the process of changing system messages.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a system message indication method, device and system. Background technique [0002] The 3rd Generation Partnership Project (3GPP) standard is based on the cellular network. By designing a new air interface and using the characteristics of narrowband technology to carry Internet of Things (IoT) services, this type of IoT is called Narrow Band-Internet of Things (NB-IoT). Compared with traditional cellular networks, the data packets generated by NB-IoT network services are smaller, the data transmission cycle is longer, and the cost of NB-IoT terminal equipment is low. Usually, there may be a large number of terminal devices under one NB-IoT base station to achieve mass deployment of terminal devices. [0003] At present, in NB-IoT, when the system information changes, the NB-IoT base station will notify the terminal device through a direct indication (direc...
