Mobile broadband device and auxiliary positioning method thereof

Abstract

The invention provides a mobile broadband device and an auxiliary positioning method thereof. The method comprises the following steps: a host initiates a positioning application to a mobile broadband device; firmware of the mobile broadband device determines whether the positioning application initiated by the host needs an auxiliary positioning function or not, and if so, the firmware initiates an auxiliary positioning data acquisition application to the host; after receiving the auxiliary positioning data acquisition application initiated by a device side, the host initiates an auxiliary positioning data acquisition application to a SUPL (Secure User Plane Location) server; the SUPL server sends auxiliary positioning data to the host; after receiving the auxiliary positioning data, the host sends the auxiliary positioning data to the mobile broadband device; by utilizing the received auxiliary positioning data, the firmware of the mobile broadband device calculates standard GPS data and outputs the standard GPS data to a positioning application program of the host. According to the device and the method in the invention, user experience is improved, a user flow is saved, a user gain is increased, load of the device side is greatly lightened, a performance index of a product is raised, and a usage scope of an auxiliary positioning function is expanded.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a mobile broadband device and an auxiliary positioning method thereof. Background technique [0002] At present, with the rapid development of communication 3G networks, users not only put forward high requirements for traditional voice services of mobile networks, but also pay more and more attention to wireless data services of mobile networks. The application of mobile broadband equipment is also very extensive. Location-based service applications (LBS) are even hotter. Terminal users' requirements for positioning functions and assisted positioning functions of mobile broadband devices have become the standard configuration of such devices. The existing positioning functions and assisted positioning functions are mainly realized based on GPS and AGPS technology, the realization of the assisted positioning function is that the host side (Host) initiates ...

AI Technical Summary

Problems solved by technology

In the network where the operator supports multiple PDP links, the mobile broadband device needs to activate two PDP links in order to support the assisted positioning function, one is used for surfing the Internet, and the other is used for obtaining assisted positioning data, and the performance of the general mobile broadband device processor is limited. , this implementation will significantly increase the processing load of the device and increase power consumption, which is fatal to mobile devices

[0006] In a network where operators only support a single PDP link, mobile broadband devices cannot access the Internet while obtaining auxiliary positioning data, seriously affecting user experience
