Problems solved by technology

Sending the Paging message repeatedly in this way means that the NB-UE needs to constantly try to receive the Paging message, which will inevitably lead to excessive power consumption of the NB-UE, and cannot achieve the purpose of saving energy for the NB-UE, and the existing paging method is adopted , unable to wake up the target UE quickly, resulting in a low success rate of paging the target UE

Embodiment Construction

[0049] In various embodiments of the invention, figure 1 It is a schematic diagram of the implementation flow of the paging method in the embodiment of the present invention, such as figure 1 As shown, the paging method includes the following steps:

[0050] Step 101, when it is determined to send a Paging message to the target UE, the eNB acquires the target coverage level corresponding to the target device ID of the target UE according to the pre-stored correspondence between the device ID and the coverage level.

[0051] In a specific embodiment of the present invention, the network side may send a Paging message to the UE in the RRC_IDLE state or the RRC_CONNECTED state. Specifically, the paging process can be triggered by the MME in the core network, or by the eNB; when the paging process is triggered by the MME, the MME first sends the Paging message to the eNB through the S1 interface, and then the eNB Initiate paging to the target UE on the Uu interface. In this ste...

Abstract

Embodiments of the invention disclose a paging method and device. The method includes the steps the steps of when determining to send a Paging message to target user equipment (UE), acquiring, by an eNB according to a pre-stored correspondence between an equipment identifier and a coverage level, a target coverage level corresponding to a target equipment identifier of the target UE; determining,by the eNB, a target paging strategy corresponding to the target coverage level according to a pre-stored correspondence between the coverage level and the paging strategy; and sending, by the eNB, the Paging message to the target UE according to the paging strategy.

Description

technical field [0001] The present invention relates to a paging technology in the communication field of the Internet of Things, in particular to a paging method and device. Background technique [0002] Cellular-based Narrow Band Internet of Things (NB-IOT) is an emerging technology in the field of Internet of Things (IOT), because NB-IOT can support the cellular data connection of low-power devices in the wide area network , also known as Low Power Wide Area Network (Low Pover Wide Area Network, LPWA). [0003] In order to meet the requirements of a large number of users and low throughput, data transmission in the NB-IOT system can be divided into two modes: Control Plane Mode and User Plane Mode. In the control plane mode, by carrying the uplink and downlink data in the signaling Non-Access Stratum Protocol Data Unit (Non-Access Stratum Protocol Data Unit, NAS PDU) for transmission, the UE only establishes the signaling radio bearer (Signaling radio bearer) after acces...
