Embodiment Construction

[0048] In a multi-interface multi-connection scenario, the LMA needs to control flow migration according to the real-time connection status of the terminal multi-interface (such as the activation and disconnection status of the interface). When a new interface is connected to the network, the LMA migrates the existing service flow that is more suitable for the new interface to the new interface according to the real-time interface status; when the interface leaves the network (for example, the connection is disconnected), the LMA needs to When the connection is disconnected, the service flow on this interface is transferred to the active and available interface. In this case, the above operation process of the LMA needs to be based on the service flow policy, and the service flow policy needs to be synchronized with the terminal.

Abstract

The invention discloses a method and system for supporting multi-interface and multi-connection communication. A multi-interface and multi-access server is deployed in a multi-interface and multi-connection network, and the multi-interface and multi-access server deployed in the multi-interface and multi-connection network obtains The state information of the terminal and / or the network distributes the service flow policy to the terminal and the network; according to the obtained state information and the distributed service flow policy, the multi-interface and multi-access server assists the mobility management entity to manage the mobility of the terminal. The invention supports multi-interface and multi-connection communication technology, can ensure the synchronization of service flow policies on the terminal side and the network side, and effectively realize the mobility management for the terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for supporting multi-interface (If, InterFace) multi-connection communication. Background technique [0002] In the development of the current network architecture, it is necessary to fully combine and utilize the advantages of various networks such as 2G / 3G / Long Term Evolution (LTE, Long Term Evolution) / Wireless Local Area Network (WLAN, Wireless Local Area Network) to achieve collaborative work between different networks. Provide users with a better business experience. [0003] Multi-network collaborative work requires mobile terminals and networks to support multiple interfaces and multiple connections. Specifically, as figure 1 As shown, for multiple interfaces, the mobile terminal needs to support multiple access methods at the same time, such as LTE, WLAN and so on. For multi-interface and multi-connection, multi-interface terminals need to be able to acces...
