Embodiment 1
[0040]This embodiment provides a method for acquiring system information, which is applied to terminals, such as electronic devices such as mobile phones, vehicle-mounted computers, and smart watches. In order to better explain the method, this embodiment uses the method of obtaining 5G system information as an example, but the method is not only applicable to 5G, but also suitable for obtaining system information in the LTE system. Here, according to the function of 5G system information To determine the sending mode and priority of each system information and other information, the specific scheduling parameters that will be involved in the method are described as follows:
[0041] As shown in Table 1, it is a table of 5G system information (MIB, SIB1-SIB9), which includes information such as description of each information function, transmission mode, and transmission priority.

[0044] In Table 1, the transmission mode includes periodic broadc...
Embodiment 2
[0086] Such as Figure 4 As shown, this embodiment provides a method for obtaining system information, which is applied to the network side, and the method includes:
[0087] Step 201, receiving a system information sending request sent by a terminal, where the system information sending request includes a sending mode of the system information.
[0088] Step 202: Send the system information to the terminal according to the sending mode of the system information.
Embodiment 3
[0090] Such as Figure 5 As shown, this embodiment provides a terminal, including a system information requirement management module 31, a system information sending and receiving module 32,
[0091] The system information requirement management module 31 is configured to determine the type of the service when the service is changed, and determine the sending mode of the system information corresponding to the service according to the number of changes of the service.
[0092] The system information sending and receiving module 32 is connected to the system information requirement management module, and is used to send a system information sending request to the network side according to the type of the service determined by the system information requirement management module and the sending mode of the system information corresponding to the service , the system information sending request includes a sending mode of the system information;
[0093] The system information tr...

Abstract
The invention provides a systeminformation acquisition method applied to a terminal. The method comprises the following steps of: during service changes, determining the type of service, determininga sending mode of system information corresponding to the service according to the change times of the service; and sending a system information sending request to a network side according to the typeof the service, with the system information sending request comprising the sending mode of the system information, and receiving the system information sent by the network side according to the sending mode of the system information. Correspondingly, the invention also discloses a system information acquisition method applied to the network side, a terminal and a base station. The problem that the terminal cannot receive required correct system information on time due to long cycle time for acquiring the system information or lack of messages in the prior art can be solved.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for acquiring and sending system information, a terminal and a base station. Background technique [0002] In the communication industry, system information is the link between the terminal and the network, and various services and physical processes of wireless communication are completed through the transmission of system information between the terminal and the wireless side. When the terminal is turned on, reselects a cell, and the handover is completed, it enters 5G from other RAT (Radio Access Type, wireless access type), E-UTRA (Evolved Universal Terrestrial Radio Access, evolved UMTS terrestrial wireless access), and receives system information changes When notifying, receiving an ETWS (Earthquake and Tsunami Warning System, Earthquake and Tsunami Warning System) notification and system information exceeding the maximum validity period and ot...
