Embodiment Construction

[0047] The technical solutions of the method and device for acquiring offline maps will be described in detail below in conjunction with specific embodiments and drawings to make it clearer.

[0048] Such as figure 1 As shown, in one embodiment, a method for obtaining an offline map includes the following steps:

[0049] Step S110, searching for the terminal, and obtaining the selected terminal to be connected.

[0050] First of all, before searching for the terminal, you need to enable the WI-FI Direct connection function. When searching, the searched terminal must also enable the WI-FI Direct connection function. When multiple terminals are found, you can manually select a terminal to be connected. It is known in advance that the offline map data has been stored in the terminal, which can facilitate the subsequent direct transmission of the offline map data.

[0051] WI-FI Direct means that devices in a wireless network can connect to each other without going through a wireless ro...

Abstract

The invention relates to a method and a device for obtaining an offline map. The method comprises the steps of searching terminals, and obtaining a selected terminal to be connected; initiating a wireless fidelity (WI-FI) Direct connection request to the selected terminal; receiving a connection confirmation request sent by the selected terminal, and establishing a WI-FI Direct connection channel according to the connection confirmation request; sending a request for obtaining the offline map according to the WI-FI Direct connection channel; and receiving offline map data sent in response to the request for obtaining the offline map. According to the method and the device for obtaining the offline map, the offline map data is transmitted through the WI-FI Direct connection channel established between the terminals, so that network traffic is saved; and furthermore, as the transmission speed of WI-FI Direct reaches up to megabytes per second, the transmission can be completed in a second, and the speed of obtaining the offline map is greatly improved.

Description

Technical field [0001] The present invention relates to data transmission technology, in particular to a method and device for obtaining offline maps. Background technique [0002] In order to find a place, people often need to use a map of that place. With the development of science and technology, people use electronic maps instead of paper maps, and learn the route to a certain place by downloading electronic maps on mobile terminals or directly querying electronic maps online through the Internet. [0003] The traditional way to obtain offline maps is to connect to WI-FI hotspots or 2G / 3G networks. However, to obtain offline maps in the application Figure one Generally, megabytes of traffic data are required. If there is no WI-FI hotspot access in other places, 2G / 3G traffic will be consumed, and the download speed will be limited. Summary of the invention [0004] Based on this, it is necessary to provide a method for acquiring offline maps that can save network traffic and ob...
