Problems solved by technology

However, in the current NB-IoT system, the network device thinks that the terminal device is in the idle state for a long time. During this period, the system information is more likely to be updated, so after the system information is updated, the network device It will notify the terminal equipment in the idle state, such as the network equipment indicating that the system information has been updated through the paging message
However, the network device thinks that the terminal device is in the connected state for a relatively short time, and thinks that the system information is less likely to be updated within a short period of time, so when the system information is updated, the network device will not notify The system information of the terminal device in the connected state has been updated
But in fact, the system information may also change during the time when the terminal device is in the connected state, but in the current NB-IoT system, the terminal device in the connected state cannot know that the system information has been updated

Embodiment Construction

[0055] In order to make the objectives, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0056] Hereinafter, some terms in the embodiments of the present application will be explained, so as to facilitate the understanding of those skilled in the art.

[0057] (1) Network devices, including access network devices, such as base stations (eg, access points), may refer to devices in the access network that communicate with wireless terminal devices through one or more sectors on the air interface. The base station may be used to convert received air frames to and from internet protocol (IP) packets and act as a router between the terminal device and the rest of the access network, which may include an IP network. The base station may also coordinate attribute management of the air interface. For example, t...

Abstract

The present application discloses a method and a communication device for acquiring system information. In this method, the terminal device receives downlink control information from the network device, the downlink control information carries first indication information, and the first indication information is used to indicate that the system information has been updated or will be updated; then the terminal device obtains the updated system information. information. In this way, the terminal device in the connected state can know that the system information has been updated or will be updated, and then can obtain the updated system information.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and a communication device for acquiring system messages. Background technique [0002] The narrow band internet of things (NB-IoT) system is built on a cellular network and can occupy at least a bandwidth of about 180KHz, and can be directly deployed in the global system for mobile communication (GSM) system, general mobile communication system (universal mobile telecommunications system, UMTS) or long term evolution (long term evolution, LTE) system, in order to reduce deployment cost and achieve smooth upgrade. [0003] At present, in the NB-IoT system, after the system message is updated, the network device will notify the terminal device. If the system message is updated, the terminal device can re-read the new system message. However, in the current NB-IoT system, the network device considers that the terminal device is in an idle state for...
