Step 122：Server issues distributing strategy to UE, so that the correspondence that UE includes according to the distributing strategy With UE obtain different type network network state information, be service selection objective network after, by service distributing to the target Network.

Optionally, before server issues distributing strategy to UE, the registration message of UE transmissions can be received, works as registration message In when supporting the ability information of concurrent transmission comprising UE, server can issue distributing strategy to UE, and UE supports concurrent transmission Ability is supported to be linked into different types of network at the same time for the UE；And/or when what the UE included in registration message was preserved divides When the version of the version of Flow Policy and the distributing strategy of the network equipment is inconsistent, server can issue distributing strategy to UE.Can Choosing, server first can also issue distributing strategy to the network equipment, distributing strategy is transmitted to UE by the network equipment.

Referring to Fig. 2, for another embodiment flow chart of the method for present invention control shunting, This embodiment describes based on Network load information control business is diverted to the process of objective network：

Step 201：UE sends registration message to the network equipment, supports the ability of concurrent transmission in the registration message comprising UE Information.

In the present embodiment, UE obtains distributing strategy from the network equipment.When UE is needed with network device communications, UE is to network Equipment sends registration message, and the ability information of UE is carried in the registration message, which refers mainly to whether UE supports concurrently, That is whether UE supports to associate multiple networks at the same time.

Optionally, when UE had obtained distributing strategy from the network equipment, then it can also include and obtain in the registration message The version information of the distributing strategy taken.

Step 202：The network equipment returns to distributing strategy according to registration message to UE.

After the network equipment receives registration message, if carrying the ability letter that UE supports concurrent transmission in the registration message During breath, then the network equipment sends distributing strategy to UE, if not carrying the ability letter that UE supports concurrent transmission in the registration message During breath, then the network equipment does not send distributing strategy to UE；Further, when the version that distributing strategy is also carried in the registration message During information, then the network equipment compares the version information of the distributing strategy in the version information and current network device, when the two not When consistent, the network equipment sends distributing strategy to UE again.

Optionally, the network equipment is before distributing strategy is sent, and can be combined with the current related networks of UE, (such as UE is current Place network, UE are currently located cell), and/or signing information (such as set meal that the UE user uses, rate) of user etc. into Row is sent.Therefore the distributing strategy for different related networks can be pre-set on the network equipment, when receiving UE transmissions Registration message, according to related network current UE and/or the signing information of user, it is determined whether need to issue shunting plan to UE Slightly, and need after issuing distributing strategy to UE, select corresponding distributing strategy to be handed down to the UE.

Optionally, the distributing strategy obtained when the network equipment to the version of the UE distributing strategies returned higher than UE During version, the network equipment only can return to changed increment information in distributing strategy to UE, be passed so as to save network Defeated resource.

Optionally, UE can return to confirmation message after distributing strategy is received to the network equipment.

Step 203：UE reports related network message to the network equipment.

The related network message that UE is reported includes the network information of at least one network.For example, the network of cellular network Information can include：The network name of 2G networks (GSM network or GPRS network), the network name of 3G network (UMTS network), 4G nets The network name of network (LTE network), cell ID etc.；The network information of WLAN can include：Service set (Service Set Identifier, SSID), MAC Address of AP etc..

Wherein, UE can report related network message in the case of following any one to network side：

The first situation：UE is changed into double gateway connection from single gateway connection, for example, UE is by only cellular network (Cellular Only) or only WLAN (WLAN only) associations are changed into cellular network and are associated at the same time with WLAN；

The second situation：When double gateways join, the network formats of some network change UE, for example, cellular network Honeycomb standard is changed into the UMTS network of 3G from the GSM network of 2G；

The third situation：When double gateways join, the network formats of network do not change UE, but cell changes, For example, UE is attached to GSM network all the time, but due to the change of UE positions, UE leaves the coverage of cell A, into cell B's Coverage；

4th kind of situation：When double gateways join, the network formats and cell of network do not change UE, and WLAN changes Become, for example, UE is moved in the coverage of cell A all the time, include the AP of multiple WLAN under the coverage of cell A, but by Change in UE positions, UE leave the coverage of AP1, are moved in the coverage of AP2；

5th kind of situation：UE is changed into single gateway connection from double gateways connection, turns for example, UE is associated at the same time from cellular network with WLAN It is changed into only cellular network (Cellular only) or only WLAN (WLAN only) associations；

Step 204：The network equipment sends network load information according to the triggering of related network message to UE.

With reference to the description of step 203, when the related network message that UE is reported includes the network information of two networks, net Network equipment can know that UE current states are that double gateways join, or will enter double gateways and join, then the network equipment can be sent out to UE SCN Space Cable Network information on load；When the related network message that UE is reported includes the network information of network, then the network equipment can Currently joined with knowing UE for single gateway, therefore the network equipment can stop sending network load information to UE.

It should be noted that above-mentioned steps 201 and step 202 can also perform after step 204, i.e., the present invention is implemented Example is not limited obtaining distributing strategy and obtaining the execution sequence of network load information.

Step 205：UE obtains the type of service of current business to be transmitted.
