State the access point IP address of LTE network.In the specific implementation, generally the access point IP address described in step S1131 is referred to as to change
Address (ChangeofAddress, COA).
Step S1132, the mobile terminal sends the instruction for asking switching to the base station of the 2G or 3G network, passes through institute
State request switching command and the IP address of the LTE network access point issued the base station of the 2G or 3G network so that institute 2G or
The base station of 3G network notifies data gateway change routing table, using the IP address of the LTE network access point as subsequently from described
Mobile terminal receives the IP address of data.
In the specific implementation, after the access point IP address of LTE network is got, the mobile terminal is to 2G the or 3G nets
The base station of network sends the instruction of request switching, and the access point IP address of the LTE network is carried into the finger in the request switching
In order, after 2G or 3G network base station receive the request switching command, the access point of the LTE network is therefrom obtained
IP address, and the IP address of the access point of the LTE network of acquisition is sent to data gateway, data gateway receives base station transmission
After new access point IP address, routing table can be changed, by the data-interface address of mobile terminal with being updated to described access point IP
Location, and to mobile terminal issue allow network switching instruction.
Step S1133, the mobile terminal, which is received, allows the switching command of network switching, disconnects and 2G the or 3G nets
The connection of network base station, so that the mobile terminal is switched to the LTE network.
Therefore, the embodiment of the present invention in mobile terminal by setting up network operator data storehouse, the network operation
Network coverage measurement result is stored in quotient data storehouse, the network coverage measurement result includes：Mobile country code MCC, movement
Network number MNC, location area code LAC, cell ID CI, the current institute frequency range Band of resident network and current resident network
Wireless access type RAT.Thus, when mobile terminal resides in 2G or 3G network, mobile terminal can be transported by the network
The network coverage measurement result information stored in battalion's quotient data storehouse judges whether 2G or 3G network periphery have available LTE network,
And after discovery has available LTE network, initiate network signal measure and perform 2G or 3G network to LTE network switching.This
In inventive embodiments, the measurement of LTE network signal is targetedly entered according to the information preserved in network operator data storehouse
Row measurement, thus, which obviating in the prior art can only the efficiency brought of blindness heuristic search periphery adjacent area LTE network signal
Low defect.Because the coverage condition for the LTE network cell for once having accessed user in network operator data storehouse enters
Storage is gone, the embodiment of the present invention can quickly realize 2G or 3G network returning to LTE network by network operator data storehouse
Switching is moved back, it can ensure that mobile terminal is quickly switched into LTE network, it is ensured that customer service (call, online etc.) is cut in network
Fluency during changing.Enhance the experience of user.

Second switch unit 60, will be described mobile whole for the switching command beamed back according to the 2G or 3G network
End is switched to LTE network.
As shown in figure 5, as a kind of feasible embodiment, the second switch unit 60 specifically may include：LTE connections are set up
Unit 601, routing update unit 602 and handoff response unit 603, wherein：
The LTE connection establishment units 601, for setting up the mobile terminal and the LTE indicated by the switching command
Network sets up connection, and obtains the access point IP address of the LTE network；In the specific implementation, generally by LTE connection establishment units
Described access point IP address acquired in 601 is referred to as changing address (ChangeofAddress, COA).
The routing update unit 602, the instruction of switching is asked for being sent to the 2G or 3G network base station, is passed through
The request switching command issues the IP address of the LTE network access point base station of the 2G or 3G network, so that institute 2G
Or the base station of 3G network notifies data gateway change routing table, using the IP address of the LTE network access point as subsequently from institute
State the IP address that mobile terminal receives data.
In the specific implementation, after the access point IP address of LTE network is got, the mobile terminal passes through routing update list
Member 602 sends the instruction for asking switching to the base station of the 2G or 3G network, and the access point IP address of the LTE network is carried
In the instruction of the request switching, after 2G or 3G network base station receive the request switching command, therefrom obtain
The access point IP address of the LTE network, and the IP address of the access point of the LTE network of acquisition is sent to data gateway, number
After the new access point IP address that base station transmission is received according to gateway, routing table can be changed, by the data-interface address of mobile terminal
It is updated to described access point IP address, and is issued to mobile terminal and allow the instruction of network switching.
The handoff response unit 603, for when receive allow network switching switching command, disconnect with the 2G or
The connection of 3G network base station, so that the mobile terminal is switched to the LTE network.
Therefore, the embodiment of the present invention in mobile terminal by setting up network operator data storehouse, the network operation
Network coverage measurement result is stored in quotient data storehouse, the network coverage measurement result includes：Mobile country code MCC, movement
