Embodiment 1

[0248] Step 1: The cell and / or node receives the system update request and completes the system information update;

[0249] The system update request received by the cell and / or node includes one or more of the following:

[0250] System information updates of cells and / or nodes themselves;

[0251] The cell and / or node will change the configuration information of the cell and / or node due to changes in the number of users in the cell and / or node, traffic volume, wireless environment, etc., including the system information of the cell and / or node change.

[0252] In order to better manage a large number of system information, system information, including critical system information and non-critical system information, can be grouped or divided into blocks, and identification information such as numbering and / or naming can be assigned to each group or block. The or block sets a value tag (value tag) indicating the update status. Every time the system information group or sys...

Embodiment 2

[0281] Step 1: The cell and / or node receives the system update request and completes the system information update;

[0282] With embodiment 1;

[0283] Step 2: The cell and / or node sends updated system information to the UE by broadcast or multicast;

[0284] In order to improve resource utilization efficiency as much as possible, update the system information of as many UEs as possible at the same time, and update the system information of all UEs in the coverage area of ​​a cell and / or node as much as possible, the cell and / or node will use broadcast or multiple broadcast the updated system information to the UE, Figure 11 It is a schematic diagram of a random access process and an RRC connection establishment process according to an embodiment of the present invention Figure three ,Such as Figure 11 As shown, it is a broadcast or multicast method based on transmission opportunities, such as multiple dynamic scheduling of paging opportunities, including:

Abstract

The invention provides a system information updating method and apparatus. The method includes the steps of generating updated system information if an update condition is satisfied, wherein the update condition includes that a cell and / or node generates a system information update request; and sending updated system information to UE in a broadcast or multicast manner, thereby solving the problem that there is no new system information updating mechanism for a transmission mechanism of new key system information and non-key system information in the related art, and ensuring the user terminal to complete the system information updating by means of broadcasting or multicasting.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for updating system information. Background technique [0002] After just a few decades of development, cellular mobile communication technology has entered the 4G era. In order to meet the foreseeable future higher, faster and newer communication needs, the industry has begun research on future 5G technology. 5G will conduct further technical research on greater throughput, more user connections, lower latency, higher reliability, and lower power consumption (including network-side equipment and user terminals). At present, the industry has proposed a 5G technical goal: by 2020, to achieve a 1000-fold increase in mobile data traffic per region, a 10- to 100-fold increase in throughput per User Equipment (UE), and a 10- to 100-fold increase in the number of connected devices , a 10X improvement in battery life for low-power devices, and a 5X reduction in end...
