Problems solved by technology

[0007] Generally, the switching of the positioning mode occurs when the device moves out of the coverage area of ​​the WLAN signal and enters the coverage area of ​​the GPS signal, when the device moves out of the coverage area of ​​the GPS signal and enters the coverage area of ​​the WLAN signal, or when the device moves between the coverage area of ​​the WLAN signal and the GPS signal. When moving within the common coverage area, in this case, due to the presence of multiple signals at the same time, the device needs to select a currently suitable positioning method to achieve positioning. However, no corresponding positioning technology switching scheme has been proposed so far.

Embodiment 1

[0059] see figure 1 , a method for positioning technology switching. The execution subject of the method is specifically a mobile device such as a mobile phone or a PDA (personal digital assistant, personal digital assistant). It should be noted that the mobile device described in the embodiment of the present invention is provided with GPS positioning Module and WLAN positioning module and GPS interface, WIFI (Wireless Fidelity, wireless fidelity) interface and WSN interface, receive GPS signal, WLAN signal and WSN signal to obtain corresponding positioning data through above-mentioned interface, comprise the following steps:

[0060] Step 101: Obtain handover reference information;

[0061] Step 102: Select a target positioning technology according to the handover reference information;

[0062] Step 103: Switch the currently used positioning technology to the target positioning technology.

[0063] Through the implementation of the technical solution provided by the embod...

Embodiment 2

[0065] Before describing the embodiment of the present invention in detail, what needs to be known in advance is: in the overlapping area of ​​the GPS signal attenuation area within the coverage of the GPS network and the coverage area of ​​the WLAN network, that is, at the entrance and exit of the building, a WSN (Wireless Sensor Network, Wireless sensor network) mark node, the coverage of the WSN mark node is the critical area where the positioning technology switches; within the WLAN coverage area, the signal is strong, that is, the WSN switch node is deployed in the building.

[0066] In addition, an area covered only by a GPS network or an area covered only by a WLAN is called a single scene in this embodiment of the present invention, and an area covered by an overlapping GPS network, a WLAN network, and a WSN network is called a mixed scene in this embodiment of the present invention, for example, a building The area covered only by the GPS network is a single scene, the...

Embodiment 3

[0126] see image 3 , a kind of mobile equipment, this mobile equipment can specifically be mobile phone or PDA (personal digital assistant, personal digital assistant), etc., comprise: acquisition module 30, selection module 31 and switching module 32;

[0127] An acquisition module 30, configured to acquire handover reference information;

[0128] A selection module 31, configured to select a target positioning technique according to the handover reference information acquired by the acquisition module 30;

[0129] The switching module 32 is configured to switch the currently used positioning technology to the target positioning technology obtained by the selection module 31 .

[0130] Specifically, the acquisition module 30 is specifically configured to receive the first information sent by the marked node and the second information sent by the switching node, both the marked node and the switching node are wireless sensor network nodes, and the first information includes ...

Abstract

The invention discloses a positioning technology switching method and a mobile device, belonging to the technical field of positioning. The method comprises the following steps acquiring switching reference information; selecting target positioning technology according to the switching reference information; switching positioning technology used at present into the target positioning technology. According to the invention, when a mobile device undergoes switching of positioning technology, the switching of positioning technology can be realized merely by acquiring switching reference information without dependence on position information of the mobile device; the switching method is simple and highly efficient.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to a positioning technology switching method and a mobile device. Background technique [0002] With the rapid development of social economy, the range of people's activities is getting wider and wider, and "location information" has become more and more important information in people's lives. For example, when people come to an unfamiliar environment, they need location information to provide them with navigation; When an emergency occurs, rescuers also need the location information of the person being assisted to rush to the scene for assistance. [0003] GPS (Global Positioning System, Global Positioning System) is currently the most widely used outdoor positioning technology. Its good positioning accuracy solves many practical problems, but GPS satellite signals are easily affected by the external environment (such as high-rise buildings and other buildings) and weakened,...
