Further, for 4G networks, 3G network and 2G networks, network type can be pre-set Priority, for example, bandwidth of the bandwidth of 2G networks less than 3G network；The bandwidth of 3G network is less than 4G The bandwidth of network, therefore, the network type priority of default network is：4G networks>3G network>2G nets Network.The network type priority of network can notify terminal beforehand through base station, it is also possible to be preset at the end In end；Optionally, it is possibility to have the priority of User Defined heterogeneous networks.

Reference picture 1, the terminal can receive the signal of base station 1, base station 2 and base station 3 transmitting, terminal Based on the signal for receiving, generate base station information list, the list can be used comprising described at least one The signal strength values of network, the network type priority of described at least one usable network, described work as The signal intensity of preceding service network, the network type priority of the current service network.

Wherein, the information of each base station that may be coupled to is stored in the base station information list, optionally, The information of the base station can include mobile phone country code (Mobile Country Code, abbreviation： MCC) mobile device network code (Mobile Network Code, referred to as：MNC) position area compile Code (location area code, referred to as：LAC)；And Base Station Identification, can be according to those acquisition of information When the corresponding network signal intensity in the base station, and network type etc..

It is assumed that terminal uses data service cards 1, and the 3G network that access base station 1 is provided, then should Current service network in 3G network respective base station information list, and terminal receives the net of the offer of base station 2 Network and the network provided with base station 3, described at least one usable net in respective base station information list Network；

Further, terminal can also obtain data service cards 1 by the traffic management module of terminal The flow service condition of flow service condition and data service cards 2.For example, obtaining data service cards 1 pair Answer the residue of network organization available stream of residue of network organization utilizable flow and data service cards 2 the correspondence operator of operator Amount；Dividing mode based on current service network above and usable network, base station information list may be used also To include：It is the residue of network organization flow of described at least one usable network correspondence operator, described current The residue of network organization flow of service network correspondence operator, the residual flow at this refers to remaining available Flow, i.e., the flow being had not been used in the flow bag that user has paid.

Due to the change of the mobility and Internet resources of terminal, terminal needs to enter above-mentioned base station information list Row is safeguarded and updated, and judges whether current service network is most based on the parameter that base station information list is included Excellent network, if in the presence of can provide the user higher quality network service or more meet user's rate demand Usable network, then terminal carry out network switching.

For terminal, how the parameter included based on base station information list judges whether current service network is most , there are various feasible implementations in excellent network, several feasible implementations are illustrated below：

Mode one：Terminal monitoring network change, if receiving the signal that new base station sends, in renewal Literary base station information list；For example, terminal receives the signal of the transmission of base station 3, then base station information row are updated Table, the base station information list after renewal is included：The signal intensity of the usable network that base station 3 provides It is usable that the network type priority of the usable network that value, base station 3 provide, base station 3 provide The residue of network organization utilizable flow of network correspondence operator；The signal of the usable network that base station 2 provides is strong What the network type priority of the usable network that angle value, base station 2 provide, base station 2 provided can be used Network correspondence operator residue of network organization utilizable flow；The signal of the current service network that base station 1 provides It is current that the network type priority of the current service network that intensity level, base station 1 provide, base station 1 provide The residue of network organization utilizable flow of service network correspondence operator.

Further, the network type priority of the usable network that terminal provides base station 3 and base station The network type priority of 1 current service network for providing is compared；Result is：What base station 3 provided 3G network of the network type priority of the 4G networks of operator 2 more than the operator 1 that base station 1 provides Network type；Then the network of residue of network organization utilizable flow and operator 1 that terminal compares operator 2 is remained Remaining utilizable flow.If the residue of network organization utilizable flow of operator 2 is remained more than or equal to the network of operator 1 Remaining utilizable flow, then 4G networks of the operator 2 that terminal provides network switching to base station 3.Need Illustrate, when the 4G networks of operator 2 of the offer of base station 3 are switched to, terminal will currently take first The data service cards of business switch from data service cards 1 to data service cards 2, then the switching for carrying out network.

Mode two：Terminal monitoring change in signal strength, if the signal of the current service network that base station 1 provides Intensity level is less than the first preset signal intensity threshold, then terminal inquires about network type in base station information list Priority is equal to or more than the network of the network type priority of the current service network that base station 1 provides, example Such as, the network type priority of the 4G networks that base station 2 provides is higher than the 3G network that base station 1 provides.Enter One step, terminal compares the 3G that the remaining utilizable flow of the 4G networks of the offer of base station 2 is provided with base station 1 The remaining utilizable flow of network, if the remaining utilizable flow of the 4G networks of the offer of base station 2 is more than or equal to Base station 1 provide 3G network remaining utilizable flow, then terminal network switching to base station 2 is provided 4G networks.Explanation is needed, when the 4G networks of operator 2 of the offer of base station 3 are switched to, terminal The data service cards of current service are switched from data service cards 1 to data service cards 2 first, then is carried out The switching of network.

Mode three：The residue of network organization utilizable flow of terminal monitoring current service network correspondence operator, if should Residue of network organization utilizable flow is less than the first preset flow threshold, then terminal inquires about net in base station information list Network type priority level is equal to or more than the net of the network type priority of the current service network that base station 1 provides Network, for example, the 3G net of the network type priority higher than the offer of base station 1 of the 4G networks that base station 2 provides Network.Further, terminal compares the signal strength values of 4G networks of the offer of base station 2 and is provided with base station 1 3G network signal strength values, if the signal strength values of 4G networks that base station 2 provides are more than or equal to The signal strength values of the 3G network that base station 1 provides, the then 4G that terminal provides network switching to base station 2 Network.Explanation is needed, when the 4G networks of operator 2 of the offer of base station 3 are switched to, terminal is first First the data service cards of current service are switched from data service cards 1 to data service cards 2, then carries out net The switching of network.

It can be seen from above-mentioned three kinds of feasible implementations, the scheme of the embodiment of the present invention is by considering The flow information of the network type priority of network, the signal intensity of network operator corresponding with network, comes Realize the network switching of multi-card terminal.So as to significantly more efficient switch to terminal can provide the user more High network quality is serviced or more meets the usable network of user's rate demand, so as to provide many cards eventually Hold the utilization rate to Internet resources.

S403：The terminal according to the residual flow of each the second network, according to default optimal flux set Meal decision condition, selects second net of optimal flux set meal from described at least one second networks Network is used as the objective network.

Then the terminal device has used flow or residual flow from each the second network is monitored, according to Default optimal flux set meal decision condition, it is most rational from those second networks to select flow package One, as objective network, is realized network switching.

Wherein, the optimal flux set meal decision condition can include：Residual flow at most, or has been used Flow is minimum etc..

It is to be touched by the residual flow deficiency under currently used network formats in this programme, in the program Hair network switching, to avoid beyond the flow package expense unnecessary for user brings, this programme terminal sets It is standby to obtain that network priority is higher than current network or multiple second nets of identical from base station information list Network, then to be flow service condition select the signal intensity or residual flow according to each the second network Objective network, completes network switching, in implementation process, it is also possible to pay the utmost attention to residual flow or net Network signal intensity, considers further that the height of network type priority, can be configured according to actual conditions, It is without limitation.

If the residual flow that the optional terminal detects current network is less than default residual flow thresholding, Then the terminal meets network switching trigger condition, then terminal can according to the signal intensity of new network, Network type priority, in residual flow (or having used the flow such as flow service condition) at least two Individual network information parameter realizes network information parameter of the terminal in step S102 according to the first data card Network information parameter determination with the second data card needs the objective network of switching.Except shown in above-mentioned Fig. 5 Embodiment scheme, also including following several implementations：

Fig. 7 is the flow chart of the method for switching network embodiment five of terminal provided in an embodiment of the present invention, such as The executive agent of the program shown in Fig. 7 be terminal device, i.e., the terminal in above-mentioned Fig. 1 and Fig. 2, for example： The equipment that mobile phone, panel computer etc. can realize data service by data card, in implementation as shown in Figure 3 On the basis of example, when terminal detects new base station information, it is determined that terminal meets network switching triggering bar Part is, it is necessary to carry out the matching process of network switching, then the terminal in step 102 is according to the first data card The network information parameter determination of network information parameter and the second data card needs the objective network of switching, specifically It is to be by step：

S501：The terminal obtains the network type of the corresponding first network of the new base station information.

S502：If the network type priority that the terminal judges go out the first network is higher than described first The network type priority of the current network of data card, then obtain the signal intensity of the first network.

In this step, after terminal detects new base station information, it is corresponding that detection obtains the new base station The network type of first network, according to the network type priority orders or the network of acquiescence that are pre-configured with Whether type priority level, detect the priority of the first network higher than current network, or with current net Network is identical, if the network type priority of the first network is less than current network, abandons this switching Process, that is, ensure that the bad network of performance should not be switched to.

After detecting priority and be eligible, the signal intensity of the first network is obtained, it is further right Signal intensity is contrasted, it is ensured that the signal quality of the network after switching is better than current network.

S503：If the terminal determines the signal intensity of the first network and the letter of the current network The difference of number intensity is more than default signal strength threshold, then obtain the first network residual flow and The residual flow of the current network.

In this step, if detecting the signal intensity of the signal intensity less than current network of first network, Then abandon this network switching process.

During judging to contrast signal intensity, first network and current net can be directly contrasted The size of the signal intensity of network, it is also possible to judge whether difference therebetween is more than default signal strength threshold, After the condition for meeting signal intensity, the residual flow of first network is finally detected, judge residual stream Whether amount disclosure satisfy that requirement.

S504：If the residual flow of the first network is big with the difference of the residual flow of the current network In default flow threshold, then the first network is defined as the objective network.

In this step, this network switching is terminated if the underfed of first network, it is to avoid Yong Huyin Unnecessary expense is produced using the network after switching, judges whether the residual flow of first network meets bar The mode of part can be：The residual flow of first network and the residual flow of current network are directly contrasted, if The residual flow of first network is more than the residual flow of current network, then meet；Or sentence according to above-mentioned Whether the residual flow of disconnected first network is with the difference of the residual flow of current network more than the threshold value for setting； Or can also direct detection used flow, judge whether exceeded default threshold value with using flow, The present invention is not limited for the judgment mode having.
