Embodiment 1

[0043] figure 1 A schematic flow chart of a handover method for an ad hoc network provided in Embodiment 1 of the present invention, as shown in figure 1 As shown, the method includes:

[0044] Step 101, the central terminal judges whether its own switching probability is greater than the switching probability threshold, if the central terminal judges that its own switching probability is less than or equal to the switching probability threshold, execute step 102; if the central terminal judges that its own When the switching probability is greater than the switching probability threshold, step 103 is executed.

[0045]The ad hoc network in this embodiment includes a central terminal, a backup terminal and multiple neighbor terminals. The central terminal is any terminal in the self-organizing network. When any terminal in the self-organizing network cannot communicate through the mobile network or wireless local area network, the terminal can send a command to start the sel...

Embodiment 2

[0074] image 3 It is a schematic flowchart of an ad hoc network handover method provided in Embodiment 2 of the present invention, as shown in image 3 As shown, the method specifically includes:

[0075] Step 201, the central terminal judges whether the mobile network traffic it has is greater than the set traffic value, if the central terminal judges that the mobile network traffic it has is greater than the set traffic value, execute step 202; if the central terminal judges Step 205 is executed when the mobile network traffic of the outgoing network is less than or equal to the set traffic value.

[0076] In this embodiment, the set flow value is 80-120MB, preferably 100MB.

[0077] Step 202, the central terminal communicates through the mobile network, and executes step 203 or step 204.

[0078] When the central terminal determines that the mobile network traffic it has is greater than the set traffic value, the central terminal communicates through the mobile network....

Embodiment 3

[0124] Figure 5 A schematic structural diagram of an ad hoc network system provided in Embodiment 3, such as Figure 5 As shown, the self-organizing network system includes a central terminal 1, a backup terminal 1' and a plurality of neighbor terminals 2. Figure 5 Four neighboring terminals 2 are taken as an example for illustration.

[0125] The central terminal 1 is used to judge whether its own switching probability is greater than the switching probability threshold, and if the central terminal 1 judges that its own switching probability is less than or equal to the switching probability threshold, the central terminal 1 is also used to report to all the neighbor terminals 2 Send the start ad hoc network command.

[0126] The backup terminal 1' is used to send an ad hoc network start command to all the neighbor terminals 2 if the central terminal 1 judges that its switching probability is greater than the switching probability threshold.

[0127] Further, the central...

Abstract

The invention discloses a switching method and device for a self-organizing network. The system comprises a center terminal, a backup terminal and multiple neighbor terminals; the center terminal judges whether the switching probability of itself is larger than a switching probability threshold or not; if not, the center terminal sends staring self-organizing network commands to all the neighbor terminals; if yes, the backup terminal sends the starting self-organizing network commands to all the neighbor terminals. According to the switching method of the self-organizing network, the center terminal judges whether the switching probability of itself is larger than a switching probability threshold or not, if not, the center terminal sends staring self-organizing network commands to all the neighbor terminals, or the backup terminal sends the starting self-organizing network commands to all the neighbor terminals, and thus rapid effective switching from a self-moving network or a wireless local area network based on an AP to the self-organizing network is achieved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a handover method and system of an ad hoc network. Background technique [0002] There are many ways of instant communication today, users can maintain timely communication with other users through 2G, 3G, 4G or AP (Wireless Access Point, wireless access point) based wireless network or the Internet. However, when the user is in a remote mountain area, a military battlefield, or the communication equipment is damaged by disaster, it is generally difficult to communicate with the surrounding users in time through the operator network or wireless network. [0003] Ad hoc networks can quickly build a mobile communication network at any time and any place without the support of hardware infrastructure. The establishment of the self-organizing network does not depend on the existing network communication facilities and has a certain degree of independence. At present, there is ...
