Embodiment Construction

[0127] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0128] The embodiment of the present invention can be used in a scenario where a UE requests a network (Network, NW) to send an On-demand SI, that is, the SI is sent by the NW to the UE when the UE has a demand.

[0129] An embodiment of the present invention provides a communication system, such as figure 1 As shown, it includes at least one UE and a network side device. The network side device may be a base station. The UE is within the cell coverage of the base ...

Abstract

Provided are a method and device for sending a system message, which relate to the field of communications and can solve the problem of network time-frequency resource waste caused by sending a systemmessage by a plurality of proprietary signaling. The method comprises the following steps: when that network side equipment receives a system message request sent by UE and the system message requestis used for requesting the first system message, the network side device can send the group identifier or the group identifier and the time-frequency resource to the UE requesting the first system message so as to send the first system message to the UE requesting the first system message in a multicast mode, or the network side device broadcasts the first system message. The embodiments of the present invention are used for a network side device to send On-demand SI to a UE.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for sending system messages. Background technique [0002] After the user equipment (User Equipment, UE) performs the cell search, the UE has achieved downlink synchronization with the cell, and can obtain the physical cell ID (Physical Cell ID, PCI) of the cell and the time slot of the detected frame. Next, the UE needs to acquire system information (System Information) of the cell in order to access the cell and work correctly in the cell. The system message is information at the cell level, that is, it takes effect on all UEs accessing the cell. [0003] Generally, system information can be divided into two categories, one is (important) important system information (SystemInformation, SI), which can be broadcast periodically on the network side, and this type of system information is generally required to be obtained by the UE in the idle state, or t...
