Communication switching method among different networks and terminal equipment thereof

Abstract

The invention relates to a communication switching method among different networks, which comprises the following steps of: sending a request for establishing a second link to a core network by a terminal through an access control device of a second network; and after completing the establishment of the second link, sending a request for releasing a first link to the terminal by the core network through an access control device in a first network. The invention has the advantages of providing and solving the technical problem of the processing of seamless switching of a multi-mode terminal between a WLAN (Wirele Local Area Network) network and a mobile wireless network in the prior art, and guarantees service quality and service experience of users during roaming. The invention provides a novel implementation system and method according to international standards of 3GPP (The 3rd Generation Partnership Project), 3GPP2, RFC (Request for Comments) and the like, which have easy implementation and capability of scale commercial popularization.

Description

【Technical field】 [0001] The invention relates to the technical field of communication, in particular to a communication switching method between different networks and terminal equipment thereof. 【Background technique】 [0002] Fixed-Mobile Convergence (FMC) technology combines the broadband advantages of fixed networks with the mobile advantages of mobile networks, enabling users to use the same UE (User Equipment) to access the core network through different access networks, and to Move and switch freely under the coverage of the access network to obtain complete services and consistent service experience. [0003] The core network referred to in the present invention is the mobile core network defined by the 3GPP organization and 3GPP2. The WLAN access technology referred to in the present invention includes the access methods of using WiFi (802.11 series standards), WiMax (802.16 series standards) and Bluetooth (Bluetooth) to access broadband networks. [0004] When a...

Problems solved by technology

At present, most of the equipment supporting MIP in the existing core network does not have the capability of large-scale commercial networking, or the commercial deployment of MIP services is not mature enough.

With the subsequent evolution from MIPv4 to MIPv6, the implementation based on MIP and compatible with IPv4 / v6 dual protocol stack will make the realization of seamless handover between heterogeneous access networks more complicated
