step 201, in an online state of the mobile device, at least one first recommended path is obtained according to preference information of a user.
At step 202, it is determined that the mobile device needs to be transitioned from an online to an offline state.
In step 203, the preference information and the localized first navigation data packet are obtained.
And step 204, acquiring at least one second recommended path according to the preference information and the first navigation data packet.
In step 201, in an online state of the mobile device, according to preference information of the user (e.g., high speed first, congestion avoidance, minimum cost, and fastest time) and a destination of the user (e.g., from a location to E location), the server obtains at least one first recommended route recommendation according to the preference information of the user, and sends the at least one first recommended route to the mobile device, where the at least one recommended route includes: path M1:A-B1-C1-D1E, path M2:A-B2-C2-D2E, path M3:A-B3-C3-D3E, user can recommend paths M from multiple1Route M2Route M3One of them is selected.
In step 202, the user selects the path M recommended by the server through step 2011:A-B1-C1-D1E, since the mobile device is on-line, the mobile device is dependent on the network, and if the network is unstable, the route navigation experience of the user is affected, in one embodiment, if the mobile device travels to B1The ground time network is unstable, and at the moment, a yaw phenomenon exists, and the mobile device needs to be switched from an online state to an offline state.
In step 203, the user preference information acquired in step 201 and the localized first navigation data packet may be set on the mobile device, so that the mobile device can perform route planning and route recommendation in an offline state.
In step 204, according to the obtained user preference information, the first navigation data packet, and the current location information of the mobile device, the mobile device may re-plan a new path (a second recommended path) in an offline state, and plan at least one second recommended path (for example, path M)4:B1-C1-D1E, path M5:B1-C5-D5E, path M6:B1-C6-D6-E) recommending to the mobile device that the at least one second recommended path may coincide with a path in the same at least one first recommended path (e.g. path M)4And path M1) And may be path information completely inconsistent with the first recommended path (e.g., path M)5Route M6And path M2And path M3) Thus, the user follows the path M according to the actual situation4Route M5And path M6To select a new path.
In an embodiment, step 204 may further obtain recommended path information of the mobile device in an online state, and in the offline state path planning process, the recommended path information of the online state may be referred to, so as to provide a second recommended path that is most reasonable for the user.
