Embodiment Construction

[0033] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0034] refer to figure 2 , is a flowchart of a method for realizing local IP access of a user equipment according to an embodiment of the present invention, and mainly includes the following steps:

[0035] In step 201, the HeNB receives an attach request from the UE, and sends the attach request to the MME.

[0036] In the attach request, information provided by the UE is carried to indicate whether the UE needs to perform local IP access, such as access to a home network or the local Internet, and further, if the system supports the UE to access multiple home networks at the same time In this scenario, the attach request may also carry information indicating whether the UE has access to multiple home network...

Abstract

The invention discloses a method, equipment and a system for realizing local IP access of user equipment. The method comprises the following steps: a home node HeNB receives the attached request of a user and sends the attached request to a mobility management entity MME; a system architecture evolution SAE load which is built for the local IP access of UE and is sent by the MME is received; and the UE is accessed to a home netweork or the local Internet by the SAE load. The invention can cause the UE to be accessed to the home network or the local Internet by the local IP.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, device and system for realizing local IP access of user equipment. Background technique [0002] The E-UTRAN (Evolved Global Terrestrial Radio Access) system introduces the HeNB GW (Home Base Station Gateway) in the logical structure, which is equivalent to expanding the S1 interface between the HeNB (Home Base Station) and the core network, so that it can be used in the system Configure more femtocells. For HeNB, HeNB GW is equivalent to MME (Mobility Management Entity). The movement of the user served by the HeNB GW between cells may not need to be handed over between MMEs. [0003] like figure 1 As shown, it is a schematic diagram of the network architecture of the existing E-UTRAN including the HeNB GW: [0004] Among them, the X2 interface is used between eNBs, and the S1 interface is used between eNBs and MME. HeNB is connected to MME through a centralized n...
