Embodiment Construction

[0034] In the embodiment of the present invention, when the source base station determines that the terminal needs to be handed over and the terminal has a LIPA connection, it sends a message containing the information of the target base station; after the gateway receives the message containing the information of the target base station and determines that the base station corresponding to the target base station information is connected to the gateway, it does not Release the LIPA connection and send a notification message; the source base station performs a handover operation after receiving the notification message. Since the gateway does not release the LIPA connection after the target base station connects itself, the LIPA connection supports mobility.

[0035] Furthermore, the solution of the embodiment of the present invention can also solve the problem of insufficient judgment of the existing access control technology when the source base station and the target base st...

Abstract

The invention relates to the technical field of wireless communication, in particular to a switching method, a switching system and a switching device, which are used for enabling an LIPA (local IP access) connection to support mobility. The embodiment of the invention is characterized in that when determining a terminal is required to be switched or the terminal has an LIPA connection, a source base station sends a message including the information of a target base station; after receiving the message including the information of the target base station and determining that the base station corresponding to the information of the target base station is connected with a gateway, the gateway does not release the LIPA connection, and sends a notification message; and after receiving the notification message, the source base station performs switching operations. After the target base station is connected with the gateway, as the gateway does not release the LIPA connection, the LIPA connection supports mobility, therefore, the LIPA connection has good service continuity, and has no influence on other devices in a core network, thus being beneficial to reducing the costs for equipment upgrades of the operators.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for switching. Background technique [0002] LIPA (Local IP Access) is a technology that allows terminals to access the local network associated with the home base station (evolved) home base station (H(e)NB, Home(evolved)NodeB). Networks include home networks, corporate networks, and more. The terminal accesses the local network through the Local Gateway (LGW). In the 3GPP Release 10 stage, the local gateway and the home base station are implemented on the same physical entity. After R10, the local gateway and the home base station can be implemented on different physical entities. [0003] LIPA control: [0004] Due to the limited access characteristics of the home base station and the local network (for example, the home network only allows family members to access), the network needs to perform access control on the term...
