Embodiment 1

[0124] Such as Figure 5A Shown:

[0125] Step 1: The UE sends a PDN connection establishment request to the network side, and the PDN connection establishment request carries a well-known APN or the request type field in the PDN connection establishment request is set to LIPA;

[0126] Step 2: The MME receives the PDN connection establishment request and obtains the subscription data of the UE;

[0127] For example, during the Attach process, the MME obtains the subscription data of the UE from the HSS.

[0128] Step 3: The MME judges whether the PLMN allows the UE to initiate a LIPA connection request according to the subscription information. If it is allowed, go to step 4; if not, reject the connection establishment request.

[0129] Step 4: According to the ID of the CSG where the UE is currently located, the MME obtains the well-defined APN corresponding to the CSG ID through static configuration or DNS server query. If this well-defined APN exists, a LIPA connection ...

Embodiment 2

[0142] Such as Figure 5B Shown:

[0143] Step 1: In the prior art, the user manually selects the CSG, which will trigger the TAU / RAU process of the UE.

[0144] Step 2: UE sends a TAU / RAU Request message to the network side.

[0145] Step 3: The MME judges whether the PLMN allows LIPA according to the subscription information of the UE. If it is allowed, the MME queries the LIPA APN that allows public access corresponding to the CSG ID locally or in the DNS according to the ID of the CSG where the UE is currently camped on. If not allowed, the MME completes the TAU / RAU process according to the existing process;

[0146] If the LIPA APN that allows public access corresponding to the CSG ID is found, go to step 4; otherwise, the MME completes the TAU / RAU process according to the existing process.

[0147] Step 4: If the PLMN is a VPLMN, determine whether the VPLMN supports the PLMN Autonomous CSG Roaming function and whether the HPLMN allows the PLMN Autonomous CSG Roaming f...

Abstract

The embodiment of the invention discloses a method, a system and equipment for establishing LIPA (Local IP Access) connection, which relates to the technical field of wireless communication, and is used for solving the problems that no information of a CSG (Closed User Group) with UE (User Equipment) located therein exists in the subscription information of the terminal UE, and when an APN (Access Point Name) is allowed by the CSG to perform LIPA, the UE can not successfully perform LIPA. In the invention, a network side searches for the APN corresponding to a mark of the CSG with the currentterminal located therein from the corresponding relationship between the pre-configured CSG marks and the APN used for public access after receiving a connection request sent by a terminal, and the LIPA connection for the terminal is established after the searching, or the searched APN is sent to the UE and the UE subscription information is modified. By adopting the invention, the UE can successfully carry out LIPA.

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 local IP access connection. Background technique [0002] Local IP access (Local IP Access, LIPA) is a technology that allows a terminal to access the local network associated with the home base station (evolved) NodeB (Home (evolved) NodeB, H(e)NB). Networks include home networks, corporate networks, and more. Specifically, the terminal accesses the local network through a local gateway (Local Gateway, LGW) connected to the home base station. [0003] In some public places, such as shopping malls, exhibition halls, etc., after the local network is deployed, users can be allowed to connect to the local network through LIPA access, so that users can obtain relevant information by accessing the local network, such as commodity prices, exhibits detailed information, etc., which can not only provide users with...
