Embodiment Construction

[0036] The system architecture of the present invention is as image 3 As shown, including the terminal, the first access network, the first access network gateway, the second access network, the second access network gateway, the packet data network PDN, the data gateway, and the policy server, it is added on the basis of the standard architecture : the interface of the policy server and the network selection server, the network status analysis server, the interface of the policy server and the network status analysis server. in:

[0037] The terminal establishes a connection to the data gateway of the packet data network through the first access network and the first access network gateway, establishes a wireless connection with the second access network, and sends a message for establishing a connection with the data gateway to the second access network gateway. Requesting, receiving the service flow routing rules of the second access network returned by the gateway of the...

Abstract

The invention provides a service stream moving method and system. A terminal establishes connection to a data gateway of a packet data network through a first access network and a first access gateway; the terminal establishes wireless connection to a second access network and sends a request for establishing connection with the data gateway to a second access gateway; the second access gateway sends a connection establishment request to the data gateway; the data gateway acquires the service stream routing rules of the first access network and the service stream routing rules of a second access network which are established according to the network information, and sends the service stream routing rules of the second access network to the terminal through the second access gateway; and the data gateway establishes, modifies or deletes the bearing of the first access network, and issues the service stream routing rules of the first access network to the terminal through the first access network. According to the invention, the problem that service stream is controlled by the network to move among the access systems when the UE accesses one PDN through two access technology networks is solved.

Description

technical field [0001] The invention belongs to the field of interoperability of heterogeneous mobile communication networks, specifically, the field of interoperation between 3GPP networks and non-3GPP networks. Background technique [0002] With the continuous development of communication technology, new broadband wireless access technologies are constantly emerging, and the coexistence and operation of multiple wireless broadband access networks has become a common phenomenon. In order to ensure the competitiveness of their own technologies, major communication standard organizations have formulated technical standards for long-term evolution. Among them, the system architecture evolution standard defined by 3GPP can support the provision of IP-based 3GPP services through different access technologies, including 3GPP access technologies, WLAN (wireless local area network) and other non-3GPP access technologies (defined by other standard organizations other than 3GPP) acc...
