Embodiment Construction

[0048] Figure 4 A flow chart of the method for realizing PDN connection selection in the present invention, such as Figure 4 Shown, the inventive method comprises the following steps:

[0049] Step 400: the terminal acquires a PDN connection selection policy.

[0050] The PDN connection selection strategy is used to select the PDN connection gateway according to the corresponding service attribute. When the service attribute is a local service, the PDN connection gateway is the local access gateway of the home base station network; when the service attribute is a non-local service, the PDN connection gateway is The access gateway of the core network is preset and saved in the policy server. The policy server is connected to the terminal, and its interface can be realized by using the OMA DM protocol. The policy server includes data management and control functions, and can provide network discovery and selection auxiliary data or other network policies according to operat...

Abstract

The invention provides a method and a system for realizing the PDN connecting selection, comprising the following steps of: acquiring a PDN connecting selection policy by a terminal; selecting a PDN connecting gateway according to the acquired PDN connecting selection policy; and finally establishing PDN connection by the selected PDN connecting gateway. The PDN connection is established by the selected local access gateway or an access gateway of a core network, thereby reasonably utilizing network resources to maximum extent, not only reducing resource occupation on a mobile core network and ensuring that users more rapidly and conveniently use services provided by Internet, but also meeting the requirement of distribution service of operators.

Description

technical field [0001] The present invention relates to home base station network technology, especially a method and system for implementing packet data network (PDN, Packet Data Network) connection selection in a home base station network that introduces local IP access (LIPA, local IPaccess). Background technique [0002] Femtocells are small, low-power base stations that are deployed in indoor places such as homes and offices. The main role of the home base station is to provide users with higher service rates, reduce the cost of using high-rate services, and make up for the lack of coverage of existing distributed cellular wireless communication systems. The advantages of femtocells are affordable, convenient, low power output, plug and play, etc. [0003] Users can directly access Internet and home network resources through the home base station, so as to realize the local IP access function of the home base station. Through the LIPA method, on the one hand, the reso...
