It is collectively covered at present in many place Non-3GPP networks and 3GPP network, UE first only accesses Non-3GPP network in general, and the network connection in Non-3GPP network between UE and PGW at this time only includes an independent Non-3GPP network connection.Referring to Fig. 3, after UE access Non-3GPP network, UE may search for cover the 3GPP network signal of its own.After UE searches the 3GPP network signal for covering its own, current individually Non-3GPP network connection can be switched to multithread aggregation gateway (Multi-Stream Aggregation Gateway by UE, MSA it) is connected to the network, UE accesses Non-3GPP network and 3GPP network simultaneously under MSA network connection, and UE in 3GPP network there are one eat dishes without rice or wine connection and in Non-3GPP there is also one to eat dishes without rice or wine to connect, and this two are eated dishes without rice or wine to connect then polymerization and are attached with core net, to obtain network service using Non-3GPP network and 3GPP network.

The internetwork connection mode of UE is switched to the method that MSA is connected to the network from independent Non-3GPP network connection by the application, including at least following steps: the first step, established in 3GPP network between UE and PGW 3GPP network connection, second step, established between AGW and MGW UE AGW with Tunnel between MGW, third step delete network connection of the UE between MGW and PGW.Wherein, second step and the not stringent sequential relationship of third step, can first carry out second step and execute third step again, can also first carry out third step and execute second step again.

Below with reference to Fig. 4~Figure 13, the switching method of the internetwork connection mode of the application is illustrated.

Referring to fig. 4, the embodiment of the present application provides a kind of switching method of network connection, is switched to the connection of multithread converging network from individual network connection with by UE, i.e., for UE to be switched to MSA network connection from individual Non-3GPP network connection, this method comprises:

Step 101:MGW receives the request message that a network element in UE, PGW, AGW is sent after UE and PGW establish 3GPP network connection, which includes the mark of the mark of AGW, the mark of UE and PGW.

Step 102:MGW establishes tunnel of the UE between MGW and the AGW according to the mark of the mark of the AGW and the UE.

Step 103:MGW deletes network connection of the UE between MGW and the PGW according to the mark of the mark of the PGW and the UE, which is switched to MSA network connection from individual Non-3GPP network connection.

In embodiments of the present invention, the 3GPP network connection between UE and PGW is first established in 3GPP network, MGW can establish tunnel and deletion UE network connection MGW and the PGW between of the UE between MGW and the AGW after 3GPP network connection is established, it realizes and the internetwork connection mode of UE is switched to MSA connection from individual Non-3GPP network connection, UE accesses 3GPP network and non-3 GPP network simultaneously after switching, UE in this way can improve the speed of business transmission by 3GPP network and non-3 GPP network come transmission services.

The embodiment of the present application provides a kind of switching method of network connection, and this method is used to UE being switched to MSA network connection from individual Non-3GPP network connection.Wherein, in embodiments of the present invention, UE current internetwork connection mode is independent Non-3GPP network connection, i.e. UE is connected solely to Non-3GPP network.After UE searches 3GPP network signal, current internetwork connection mode is switched to MSA network connection by UE request.Referring to Fig. 5, which includes: the 3GPP network connection established between UE and PGW in 3GPP network；MME sends tunnel to AGW and establishes request, and tunnel connection of the UE between MGW and AGW is established in request；Delete network connection of the UE between MGW and PGW.

The detailed process of above-mentioned three steps handoff procedure is specifically included referring to Fig. 6:

Step 201: after UE searches 3GPP network signal, UE sends switching request to AGW and disappears Breath, the handoff request message include the mark of the mark of UE and the MGW of UE access.

UE initially only accesses Non-3GPP network, and there is network connection in Non-3GPP network between a MGW, which is the MGW of UE access.

Optionally, after UE access Non-3GPP network, also search in real time can cover the 3GPP network signal of its own, which is the signal of eating dishes without rice or wine of the AGW broadcast in 3GPP network；After searching the 3GPP network signal of one or more AGW broadcast, UE determines handover network connection type, and selects an AGW, obtains the MGW of its access, switching request message is sent to the AGW of selection, which includes the mark of UE and the mark of the MGW.

Optionally, UE select AGW mode there are many, for example, UE can from received 3GPP network signal the strongest 3GPP network signal of selection signal intensity, then obtain the corresponding AGW of the strongest 3GPP network signal of the signal strength；For another example, UE obtains its operator belonged to, and selection belongs to an AGW of the operator in the corresponding AGW of each 3GPP network signal received from it.

Optionally, the switching request message that UE is sent further includes MSA instruction information, and independent Non-3GPP network connection is switched to MSA connection for requesting by MSA instruction information.Wherein, which can not also include MSA instruction information.

Wherein, it should be understood that the first step of the internetwork connection mode of switching UE is: establishing the 3GPP network connection between UE and PGW in 3GPP network, 3GPP network connection includes the control plane connection and the connection of user face between UE and PGW.The 3GPP network connection established between UE and PGW in 3GPP network is illustrated in step 202-212.

Optionally, UE selects the mark that the AGW can be saved after the AGW, and the upload control face connection between such UE and the AGW has been established.I.e. when UE needs to send the signaling of control plane to AGW, UE can send the upload control face between the signaling, that is, UE and AGW to the AGW according to the mark of the AGW of storage and be connected to.

Wherein, in the present embodiment, AGW can be the 3GPP network element such as evolved base station (Evolved Node B, eNodeB), SGW.Address agreement (Internet Protocol, IP) etc. that the mark of AGW can interconnect between the network of AGW.MGW can be credible wlan network (Trusted WLAN (Wireless Local Area Networks, WLAN) Access Network, TWAN), packet data gateway (the Evolved Packet Data Gateway of evolution, the non-3 gpp network element such as ePDG), or even can also be AGW.The mark of MGW can be the IP address etc. of MGW.

Step 202:AGW receives the switching request message, is connected according to the control plane that the switching request message is established between the UE, forwards the switching request message to MME.

Optionally, AGW receives the MSA instruction information included after the switching request message according to the handoff request message and determines the internetwork connection mode for needing to switch UE, then port is distributed for the UE, the mark for the UE that the handoff request message includes and the corresponding relationship of the port are saved, the downlink control plane connection between the such AGW and UE has been established.I.e. when AGW needs to send the signaling of control plane to UE, AGW can obtain corresponding port according to the mark of the UE of storage, the signaling is sent to the UE by the port, downlink control plane between namely AGW and UE has been connected to, and the upload control face between UE and AGW has been connected to, so control plane connection at this moment between the AGW and the UE has been established.

Optionally, after AGW receives the switching request message, also save the corresponding relationship of the mark and the mark of the MME of the UE, upload control face connection of such UE between the AGW and the MME has been established, that is AGW is when receiving the signaling of UE transmission, the mark for the UE for including according to the signaling gets the mark of the MME, sends the signaling to the MME according to the mark of the MME, that is, upload control face of the UE between the AGW and the MME has been connected to.

Step 203:MME receives the switching request message, establishes control plane of the UE between MME and the AGW according to the switching request message and connects, authenticates, and after the authentication is passed to UE, obtain the subscription data of UE.

The subscription data of UE be the corresponding user of UE with operator's signing service when generate.When generating the subscription data of UE, the subscription data of the mark of the UE and the UE is stored in the mark of the UE in HSS and the corresponding relationship of subscription data by operator.

Optionally, this step can be with are as follows: MME receives the switching request message, the mark, the mark of MGW and MSA that UE is extracted from the switching request message indicate information, indicate that information determines to need to switch the internetwork connection mode of UE according to the MSA, then the corresponding relationship between the mark of the UE and the mark of the AGW is stored, to realize the control plane connection for establishing UE between MME and AGW, UE is authenticated, and subscription data acquisition request message is sent to HSS after the authentication is passed, which includes the mark of UE.HSS receives the subscription data acquisition request message, and according to the mark for the UE that the subscription data acquisition request message includes, from the subscription data for obtaining UE in the corresponding relationship of the mark of stored UE and subscription data, the subscription data of UE is sent to MME.MME receives the subscription data for the UE that HSS is sent.

Wherein, currently there are a variety of authentication modes, MME can authenticate UE using any authentication mode occurred at present.It include the identity information etc. of user in the subscription data of UE, for example, the subscription data includes Gold Subscriber or Bronze Subscriber, Gold Subscriber or Bronze Subscriber are a kind of identity information Specific example.

Wherein, it should be understood that MME stores the corresponding relationship between the mark of the UE and the mark of the AGW, indicate that downlink control plane of the UE between MME and AGW has been established, i.e. after MME receives the signaling for needing to be sent to UE, MME obtains the mark of corresponding AGW according to the mark of the UE, the signaling is sent to the AGW according to the mark of the AGW, the signaling is forwarded from AGW to UE again, downlink control plane of the namely UE between MME and AGW is connected to, and upload control face of the UE between AGW and MME has been connected to, completion has been established in control plane connection of so at this moment UE between MME and the AGW.

Step 204:MME selection SGW and the PGW for obtaining UE access send conversation establishing request message to the SGW, which includes the mark of UE, the subscription data of UE and the mark of the PGW.

Optionally, this step can be that MME is that UE selects a SGW, according to the mark of the UE, the mark of the PGW of UE access be obtained from HSS, the PGW of UE access is the PGW that there is network connection between UE in Non-3GPP network.MME sends conversation establishing request message to the SGW, which includes the subscription data of UE and the mark of the PGW.

Wherein, there are many modes that MME is UE selection SGW, for example, MME can select SGW according to the position of UE, optionally, selects a SGW nearest from UE；For another example, MME selects SGW according to the loading condition of each SGW, and optionally, selection loads the smallest SGW.

In the corresponding relationship of the mark of the mark and PGW of the UE of HSS storage, when being connected to Non-3GPP network, UE is first established with MGW and is connected to the network UE, and then MGW is connected to the network with PGW foundation again, so that the UE access PGW；Simultaneously HSS by the mark of the mark of the UE and the PGW be stored in itself UE mark and PGW mark corresponding relationship in.

Correspondingly, in this step, MME sends acquisition request message to HSS, which includes the mark of the UE；HSS obtains the mark of the PGW of the UE access according to the mark of the UE from the mark of the UE itself stored and the mark of PGW, and the mark of the PGW of UE access is sent to MME；MME receives the mark of the PGW again.

Wherein, the corresponding relationship of the mark and the mark of the SGW of the UE is also saved after MME selection SGW, so realize the upload control face connection for establishing UE between the MME and the SGW, i.e. after MME receives the signaling that UE is sent, the mark for the UE for including according to the signaling obtains the mark of corresponding SGW, the signaling is sent to the SGW according to the mark of the SGW, that is, upload control face of the UE between the MME and the SGW has been connected to.

Wherein, conversation establishing request message can be Create Session Request in this step.

Step 205:SGW receives the conversation establishing request message, establishes control plane connection of the UE between SGW and MME, and the mark for the PGW for including according to the conversation establishing request message forwards the conversation establishing request message to corresponding PGW.
