Embodiment Construction

[0033] In the embodiment of the present invention, when the terminal needs to establish a PDN (Packet Data Network, packet data network) connection, it sends the first notification information indicating whether itself accepts the LIPA connection to the core network control node, and the core network control node determines that the terminal accepts the LIPA connection. , establishing a LIPA packet data network PDN connection with the terminal. Since the LIPA access in the macro base station scenario is supported, and the terminal can participate in determining the establishment of the LIPA connection, it can meet the requirements for establishing the LIPA connection in R11.

[0034] In the following description process, we first describe the cooperative implementation of the network side and the terminal side, and finally describe the implementation of the network side and the terminal side respectively, but this does not mean that the two must be implemented together. In fact...

Abstract

The embodiments of the present application relate to wireless communication technology field, and particularly relate to an LIPA connection establishment method, system and apparatus for establishing LIPA connection in R11. The Method according to the embodiments of the present application comprises: determining whether an LIPA connection is acceptable when a terminal needs to establish a PDN connection; sending a first notification by the terminal to a core network control node, indicating whether the terminal itself will accept the LIPA connection in order to notify the core network control node to establish an LIPA PDN connection with the terminal when the terminal has determined that the terminal will accept the LIPA connection. Since LIPA access is supported in a macro base station scenario, and the terminal can take part in decision-making of the LIPA connection establishment, requirement for establishing the LIPA connection in the R11 can be satisfied, thus further improving performance of the R11.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for establishing a LIPA connection. Background technique [0002] LIPA (Local IP Access) defined in R10 (version 10) is a technology that allows terminals to access the local network associated with the home base station through the home base station. The local network includes home networks, enterprise networks, etc. . The terminal accesses the local network through a local gateway (LGW, Local GateWay). [0003] The LIPA connection establishment in the H(e)NB ((evolved) home base station) scenario uses per APN (Access Point Name, access point name) and per CSG (Closed Subscriber Group, closed subscriber group) access control, network control The node judges whether to establish a LIPA connection for the user according to the APN and CSG information signed by the user, without the participation of the terminal. [0004] Sin...
