Problems solved by technology

[0007] Although IFOM can realize seamless switching of IP flows between networks, IFOM needs to put forward higher requirements on the functions of existing UEs. UEs need to support DSMIPv6 stack and corresponding functions, for example: allowing UEs to register multiple addresses at the same time , that is, multiple transfer addresses (Home Address, COA) to a home address (Home Address, HOA), maintain binding information and routing policies, expand BU messages and register binding information to HA, and communicate with HA, transfer routing filtering Traffic registration information and other functions, while the existing IPV4-based traditional UE will not be able to enjoy the communication quality and new functions of IFOM's seamless handover

Embodiment 1

[0032] Embodiment 1. A method for seamless integration of multi-network IP service flows, the flow diagram of which is as follows figure 1 shown, including:

[0033] A1, the user equipment UE that has already connected to the first network detects the signal of the second network, and then connects to the second network; the process of accessing the second network can be performed manually or automatically according to the local policy, and the specific access process can refer to the existing There is an agreed conventional flow, which does not constitute a limitation of the present invention. In the embodiment of the present invention, the first network is a 3GPP network, and the second network is a non-3GPP network. 3GPP network technologies mainly include: 3GPP includes GSM / EDGE Radio Access Network (GERAN), UMTS Terrestrial Radio Access Network (UTRAN) and evolved UMTS Terrestrial Radio Access Network. (E-UTRAN). Non-3GPP access networks mainly include: WLAN, WiMAX, CD...

Embodiment 3

[0079] Embodiment 3, a mobile anchor device 500, the structure diagram is as follows Figure 5 As shown, it includes: a DHCP agent unit 510, which is used to assist the UE to obtain an IP address as a DHCP agent after the UE accesses the network, and determine whether the UE belongs to the network where the mobility anchor is located according to the IP address obtained by the UE. If not, the agent The UE completes the discovery process of the home agent HA;

[0080] The mobile agent unit 520 is configured to use the signaling of the DSMIPv6 protocol to interact with the HA to establish a new routing binding relationship after the agent initiation unit 510 completes the discovery process of the HA, and transfer all or part of the services of the UE to the first network. offload to the second network;

[0081] The data forwarding unit 530 is configured to, after the binding unit 520 completes the binding, receive the data packet sent by the HA to the UE, and forward the data p...

Embodiment 4

[0091] Embodiment 4: A WLAN network access controller, the access controller includes: the mobility anchor device described above, and it is a reasonable choice for the mobility anchor device to be integrated into the access controller, if Arranging the mobile anchor points on the access points requires a large number of deployments, which is not conducive to the operation and maintenance management of the network. If the mobile anchor points are arranged on the core network elements, the routing of the original data packets cannot be realized. At the same time It is also not conducive to the optimization of transmission and wastes resources.

Abstract

The invention discloses a method, a communication system and a related device for seamless fusion of multi-network IP (internet protocol) business flows. In order to implement the function of IFOM (IP flow mobility) of UE (user equipment) based on IPv4 (IP version 4), an HA (home agent) is discovered by a mobile anchor point agent UE; the mobile anchor point serves as an agent of the UE according to a strategy and network condition by using a signal of DSMIPv6 (dual-stack mobile IPv6) to interact with the HA, and total or partial business flows of the UE in a first network are unloaded to a second network; and support requirements of the UE for the DSMIPv6 are shifted up to the mobile anchor point on a network side, seamless switching of business flows among networks can be achieved without upgrading a traditional terminal of an existing network, and accordingly network compatibility is increased, mobile support among networks is provided when business continuity is guaranteed and perfect fusion of the networks is achieved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and related device for seamless integration of multi-network IP service flows. Background technique [0002] With the rapid development and gradual maturity of wireless mobile communication and computer network technology, as well as the gradual expansion of people's daily work and activity space, and the increasingly frequent information exchange, the Internet has become an important platform for people to communicate with each other, obtain information, work together and interact with each other. means. At present, the technologies and ways for people to access the Internet are constantly being enriched, and the number of users using new Internet devices such as mobile terminals is gradually increasing, showing a trend of mobility. People's potential mobility needs for information interaction and sharing not only promote the development of mobile Intern...
