Description of the drawings
Fig. 1 is the flow chart of the method for switching network of present embodiment；
Fig. 2 is the Organization Chart of the network switching device of present embodiment.
Specific embodiment
Have many advantages, such as to cover wide and high mobility, therefore cellular mobile network can be passed through in view of cellular mobile network
It solves wlan network and the interruption that when connection is abnormal to be disconnected and connect phenomena such as unstable, caused WLAN data is transmitted, shadow occurs
The problem of user uses is rung, ensures that user can remain online in use.
Present embodiment keeps the link of two or more successful connections in terminal, wherein a link is used as and works as
The primary link of advance industry business, link other than primary link as spare auxiliary link, when primary link when something goes wrong, move rapidly
Move on to an auxiliary chain road, and by routeing and the method for interface Synchronization Control solves the select permeability of auxiliary link, below with
For quickly being selected between WLAN and cellular mobile network.
Present embodiment realizes that the fast transferring of network should based on the control being route to link and the control of link connection
With solving wlan network disconnection extremely leads to user's disconnection, improves user experience.
As shown in Figure 1, the method for switching network of present embodiment includes：
Step 101：Starting up of terminal opens user interface (UI)；
Step 102：Terminal is detected whether there are link connection, if it does not exist, then performing step 110；If it is present
Perform step 103；
Step 103：Whether the link that terminal judgement detects is WLAN links, if it is, performing step 104；Otherwise,
Perform step 107；
Step 104：Terminal shows WLAN connections on UI, and initiates the connection of cellular mobile network link；
Step 105：Terminal judges whether the connection of cellular mobile network link succeeds, if it succeeds, performing step
106；Otherwise, step 104 is performed；
Step 106：The routing of terminal backup cellular mobile network link, and cellular network chain is deleted in System Routing Table
The routing on road terminates；
The routing of cellular network link is deleted in System Routing Table, only retains currently used WLAN in System Routing Table
The routing of link.
Step 107：If the link detected is cellular mobile network link, terminal shows cellular mobile network on UI
It connects (such as TD-SCDMA), and initiates the connection of WLAN links；
Step 108：Terminal judges whether the connection of WLAN links succeeds, if it succeeds, performing step 109；Otherwise, it holds
Row step 107；
Step 109：The routing of terminal backup cellular mobile network link, and delete cellular mobile network in System Routing Table
The routing of link, terminal show WLAN connections on UI, terminate；
Here the presence of link is kept by deleting the route implementing of cellular mobile network link, but makes lost route,
Business is made to walk WLAN, it is consistent with the display of UI.
Step 110：Terminal initiates the connection of WLAN links and cellular mobile network link simultaneously, in WLAN links and honeycomb
When mobile network links successful connections, terminal shows WLAN connections on UI, and backs up the routing of cellular mobile network link,
The routing of cellular mobile network link is deleted in System Routing Table；
If WLAN links connect not successfully, above-mentioned steps 107 are performed；If the failed connection of cellular mobile network link,
Then perform above-mentioned steps 104.
Step 111：Terminal, according to the priority that cellular mobile network links, selects excellent when WLAN links disconnect extremely
The first highest link of grade restores the route stand-by (Millisecond) of the cellular mobile network link of selection, service switching to selection
Cellular mobile network chain road, terminal simultaneous display on UI move to cellular mobile network link (such as TD- of selection
SCDMA)；
WLAN links may cause to disconnect due to poor signal quality or other factors.
The priority of cellular mobile network link is that association rate priority and link dynamic priority are calculated.Speed
Rate priority determines that rate is bigger, and rate priority is higher by transmitted data on network rate, and series is represented with natural number, numerical value
Bigger rate priority is higher.Link dynamic priority is determined according to P values, P=frequency of abnormity/connection number, and P values are smaller
Priority is higher, divides the different brackets of link dynamic priority accordingly, and series is represented with natural number, numerical value bigger priority
It is higher.The priority that rate priority and the product of link dynamic priority are linked as cellular mobile network, product are bigger
Priority is higher.
For example, when the priority of TD-SCDMA links is higher than the priority of WCDMA links, then restore TD-SCDMA links
Route stand-by.
Step 112：Terminal timing scan wlan network is all higher than setting in the signal value that the secondary scannings of continuous N (N ＞ 1) obtain
Fixed connection threshold value, and last time signal value RnNot less than last time signal value Rn-1When, terminal initiates the company of WLAN links
It connects, after successful connection, display is switched to WLAN links on UI, while backs up cellular network link routing, and route in system
The routing of cellular mobile network link is deleted in table, business is made to walk WLAN links.
