Problems solved by technology

Due to the huge number of IoT devices and the limited capacity of the NB-IoT network, when a large number of IoT devices access the network at the same time, when a large amount of data initiates the download of GNSS auxiliary data concurrently, the NB-IoT network may be overloaded, resulting in network congestion, which in turn causes some device business abnormalities Or the power consumption is too high, the setting will lead to the collapse of the NB-IoT network, and may even cause the IoT (Internet of Things) server to be overloaded, which will cause business abnormalities

Embodiment Construction

[0045] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. The connection in the present invention includes various methods capable of forming communication connections, including but not limited to wired methods and various wireless communication methods that use communication lines, wires, etc. to realize connections.

[0046] The present invention provides a system for reducing the peak load of the cellular network (NB-IOT) / server (IoT Server), such as figure 1 As shown, the device includes three parts: a cellular network cell (NB-IoT Cell), a positioning terminal device (GNSS UE) and an assistance data server (GNSSAiding Server). The server end is connected to each cellular network cell, and each cellular network cell ...

Abstract

The invention provides a method and a system for reducing a load peak value of a cellular network / server. The method comprises the steps that each piece of GNSS UE sends a request to download new Aiding from a server side through a data communication terminal before the Aiding fails; the server side returns the Aiding to the GNSS UE when the GNSS UE requests to download data; and the GNSS UE provides the downloaded Aiding for a GNSS positioning terminal for positioning before the positioning, wherein the GNSS positioning terminal is used for searching for and receiving satellite signals according to the Aiding and carrying out position calculation. According to the invention, an NB-IoT network load peak value is reduced in a mode of dispersing Aiding expiration time, the concurrency degree can be effectively reduced, NB-IoT congestion caused when a large amount of equipment is networked is avoided, the Aiding downloading success rate is improved, the network paralysis probability is reduced, and the stability of positioning services is further improved.

Description

technical field [0001] The invention belongs to the field of the Internet of Things, and in particular relates to a method and system for reducing the peak load of a cellular network / server. Background technique [0002] The current NB_IOT (cellular-based narrowband Internet of Things) has a low rate and capacity, and data terminals integrated with GNSS functions will be limited by this technology when obtaining assistance data. For the rapid positioning of GNSS, GNSS needs to obtain auxiliary data from the server through the network, and the auxiliary data has a certain period, and new data needs to be downloaded after expiration. Due to the huge number of IoT devices and the limited capacity of the NB-IoT network, when a large number of IoT devices access the network at the same time, when a large amount of data initiates the download of GNSS auxiliary data concurrently, the NB-IoT network may be overloaded, resulting in network congestion, which in turn causes some device...
