Embodiment 1

[0086] see figure 2 As shown in the flow, this embodiment negotiates flow migration information by enhancing existing signaling on the 3GPP side (EUTRAN). Based on the network architecture, the S5 / 8 interface adopts the GTP protocol. Proceed as follows:

[0087] Step 201: the terminal UE has established multi-access from the 3GPP access network (EUTRAN) and the non-3GPP access network;

[0088] Step 202: The UE decides to initiate flow migration, the UE initiates the "UE-initiated bearer resource modification" operation from the 3GPP network, and the UE sends a "request bearer resource modification" message of the NAS message family to the MME, and the message carries flow migration information;

[0089] For the specific content of the stream migration information, refer to the description in Embodiment 13.

[0090] Step 203: The MME sends a bearer resource command message of the GTP message family to the S-GW, and the message carries flow migration information;

[0091] ...

Embodiment 2

[0109] see image 3 As shown in the flow, this embodiment negotiates flow migration information by enhancing existing signaling on the 3GPP side (EUTRAN). Based on the network architecture, the S5 / 8 interface adopts the GTP protocol. The steps are similar to Embodiment 1, but there are differences: in Embodiment 1, 204a-208 as the response signaling of steps 202-203a also has the function of creating or updating or deleting resources on the 3GPP network side; but in this embodiment Among them, the function corresponding to steps 304a-308 is only a response to steps 302-303a, and in steps 308a-308e, its function is to create or update or delete the bearer on the 3GPP network side. This step is a network-initiated process in the prior art Host resource create or update or modify operations. Therefore, step 304a does not need to wait for step 304, that is to say, there is no strict sequence relationship between step 304 and step 304a.

Embodiment 3

[0112] see Figure 4 As shown in the flow, this embodiment negotiates flow migration information by enhancing existing signaling on the 3GPP side (EUTRAN). Based on the network architecture, the S5 / 8 interface adopts the PMIPv6 protocol. Proceed as follows:

[0113] Steps 401-403: same as steps 201-203;

[0114] Step 403a: S-GW sends a PBU (proxy binding update, proxy binding update) message to P-GW, and the message carries flow migration information;

[0115] Step 404: Optionally, the P-GW and the PCRF perform an IP-CAN session modification operation;

[0116] Step 404a: The P-GW sends a PBA (proxy binding Ack, proxy binding confirmation) message to the S-GW, which may carry flow migration information that the P-GW allows migration or may not carry flow migration information;

[0117] In this embodiment, the P-GW sends a PBA message to the S-GW; the S-GW reconfigures the bearer resources on the 3GPP network side by initiating any one of the following messages: create a be...

Abstract

The invention discloses an implementing method of flow migration, a terminal and a grouped data network gateway, and is capable of avoiding modification on a non-3rd generation partnership project (3GPP) access network and an internet engineering task force (IETF) protocol and simplifying an operation procedure, wherein the method comprises a step of: establishing a plurality of accesses of same public data network (PDN) connection on a terminal, and migrating a dataflow by the P-GW by a 3GPP network signaling and packet work gateway (P-GW) negotiation flow migration information; the P-GW comprises a receiving module and a flow migrating module, wherein the receiving module is used for receiving the flow migration information transmitted by the terminal, and the flow migrating module is used for migrating dataflow according to the flow migration information received by the receiving module; the terminal comprises a connection establishing module and a negotiation module, wherein the connection establishing module is used for establishing the plurality of accesses in the same PDN connection; and the negotiation module is used for negotiating the flow migration information with the P-GW through the 3GPP network signaling after the plurality of accesses of the same PDN connection are established by the connection establishing module.

Description
