Problems solved by technology

[0007] The present invention is proposed in view of the problem that the flow migration in the related art is initiated by the terminal side, which causes the LMA to be unable to perceive the connection status of the terminal. Therefore, the present invention provides a flow migration method and device to at least solve the above problems

Embodiment 1

[0047] Figure 4 is an interactive flowchart of the flow migration method according to the preferred embodiment 1 of the present invention, as Figure 4 As shown, the following steps S402 to S416 are included.

[0048] Step S402, MAG1 perceives the current state of the terminal. The specific method for the MAG to perceive the terminal status can be the neighbor unreachable detection in the neighbor discovery mechanism, or the MAG can send PING packets to the terminal, etc. In addition, depending on the access network, it is also possible to use the measurement defined by the corresponding access network Way.

[0049] Step S404, MAG1 sends a proxy binding update message to the LMA, and the message carries the terminal status and the corresponding access network type. The terminal state may be connected state, disconnected state, sleep / power saving state or out of service area. The access network type here is the existing technology, but here it needs to be bound with the te...

Embodiment 2

[0058] Figure 5 is an interactive flow chart of the flow migration method according to the preferred embodiment 2 of the present invention, such as Figure 5 As shown, the following steps S502 to S520 are included.

[0059] From step S502 to step S504, the LMA initiates a flow migration query / response to MAG1 and MAG2, which is used to trigger reporting of the current state of the terminal. Wherein, step S502 and step S504 may occur at the same time, without any order.

[0060] Step S506, MAG1 perceives the current state of the terminal.

[0061] Step S508, MAG1 sends a proxy binding update message to the LMA, and the message carries the terminal status and the corresponding access network type. The terminal state may be connected state, disconnected state, sleep / power saving state or out of service area. The access network type here is the existing technology, but here it needs to be bound with the terminal state and stored on the LMA.

[0062] In step S510, the LMA sen...

Embodiment 3

[0069] Image 6 is an interactive flowchart of the flow migration method according to the third preferred embodiment of the present invention, such as Image 6 As shown, the following steps S602 to S620 are included.

[0070] Step S602, MAG1 perceives the current state of the terminal.

[0071] Step S604, MAG2 perceives the current state of the terminal. This step and the initiation of step S602 may be performed at the same time, in no particular order.

[0072] The above step S602 and step S604 are executed periodically, so that the terminal status stored on the MAG is kept up to date.

[0073] From step S606 to step S608, the LMA initiates a flow migration query / response to MAG1 and MAG2, which is used to trigger the MAG to report the current state of the terminal and the binding relationship of the access network type.

[0074] Step S610, MAG1 sends a proxy binding update message to the LMA, and the message carries the terminal status and the corresponding access networ...

Abstract

The invention discloses a flow migration method and device. The method includes: local mobility anchor point LMA respectively obtains the status information of terminals in multiple access networks; based on the status information and preset operator policies, Select one of the access networks and initiate flow migration. In the present invention, the MAG sends the connection status information of the terminal to the LMA, ensuring that the LMA can correctly select the access network to initiate flow migration.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a flow migration method and device. Background technique [0002] Transmission Control Protocol / Internet Protocol (Transmission Control Protocol / Internet Protocol, referred to as TCP / IP), in the initial design, did not consider the situation that the topological position of the terminal will change, that is, the TCP / IP protocol itself does not support mobility. In the traditional TCP / IP network environment, IP provides the routing function for the Internet (Internet). It assigns logical addresses, that is, IP addresses, to all nodes (including hosts and routers), and each port of each host is assigned an IP address. An IP address includes a network prefix and a host part. The IP addresses of all hosts on the same link usually have the same network prefix but different host parts. This enables IP to perform route selection based on the network prefix part of the IP address...
