Problems solved by technology

If the target Local eNB is used as the bearer transfer process of the macro eNB, the bearer transfer of the user may fail, which will affect the service reception and transmission of the user, because when the CSGLocal eNB adopts the hybrid access mode, only UEs belonging to the CSG are allowed to access , if the bearer of the non-CSG UE is transferred to the CSG Local eNB, the transfer of the user bearer will fail; when the eNB adopts the closed access mode, only the CSG UE belonging to the CSG Local eNB is allowed to access. The bearer of the UE in the CSG of the eNB is transferred to the CSG Local eNB, which will cause the failure of the transfer of the user bearer

example 1

[0110] After receiving the measurement report reported by the terminal, the Macro eNB determines that the DRB of the terminal needs to be transferred to the CSG Local eNB;

[0111] The bearer transfer request sent by the Macro eNB to the CSG Local eNB is a user plane handover message;

[0112] After receiving the user plane handover completion message sent by the terminal, the Macro eNB determines that the bearer transfer is completed; the Macro eNB sends the CSG identity and access mode information of the CSG Local eNB to the MME through a path switch request message; The request response message receives the information returned by the MME on whether the terminal is allowed to access the CSG Local eNB or the CSG member status information of the terminal; the Macro eNB sends the information returned by the MME to the CSG Local eNB through the Path Switching Request Response message.

example 2

[0114] After receiving the measurement report reported by the terminal, the Macro eNB determines that the DRB of the terminal needs to be transferred to the CSG Local eNB;

[0115] The bearer transfer request sent by the Macro eNB to the CSG Local eNB is a DRB link configuration message;

[0116] After receiving the radio resource control (RRC) connection reconfiguration complete message sent by the terminal, the Macro eNB determines that the bearer transfer is completed; the Macro eNB sends the CSG identity and access mode information of the CSG Local eNB to the MME through the CSG check request message ; The Macro eNB sends the information returned by the MME to the CSG Local eNB through a CSG modification message.

example 3

[0118] After the Macro eNB receives the initial context establishment request sent by the MME during the service request process initiated by the terminal, it determines that the DRB of the terminal needs to be transferred to the CSG Local eNB;

[0119] The bearer transfer request sent by the Macro eNB to the CSG Local eNB is a bearer establishment request message;

[0120] After the Macro eNB receives the RRC connection reconfiguration complete message sent by the terminal, it determines that the bearer transfer is completed; the Macro eNB sends the CSG identity and access mode information of the CSG LocaleNB to the MME through the CSG check request message; the Macro eNB modifies the CSG through the CSG The message sends the information returned by the MME to the CSGLocal eNB.

[0121] As another implementation manner, in step 80, the Macro eNB determines whether to allow the terminal to access the CSG Local eNB, and the specific implementation may be as follows:

Abstract

The embodiment of the invention discloses a load transferring method and load transferring equipment, which are used during layered network organization, and relates to the field of wireless communication. The method and the equipment are used for preventing failure of user surface load transfer to the greatest extent so as to improve user communication quality. After judging that data wireless load (DRB) of a terminal is required to be transferred to a closed user group local base station (CSG Local eNB), a macro base station (Macro eNB) determines whether to allow the terminal to be accessed to the CSG Local eNB or not, if so, a load transferring process is initiated to the CSG Local eNB, the CSG Local eNB receives a load transferring request which carryies the CSG member state information of the terminal and is sent by the Macro eNB, and the separated load of the terminal is accepted and controlled according to the CSG member state information. Therefore, by the method and the equipment, the problems can be avoided.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a bearer transfer method and equipment in layered networking. Background technique [0002] Statistics show that a single-layer overlay network composed of traditional macro base stations (Macro eNBs) can no longer meet people's ever-increasing demands on data service rates and capacities. Therefore, the third generation mobile communication standardization organization (3rd Generation Partnership Project, 3GPP) introduced a hierarchical networking method to solve this problem, that is, by deploying some low-power The base station is the local base station (Local eNB) (including femtocell base station (Femto) / micro base station (Pico) / relay (Relay) and other forms), to obtain the effect of cell splitting, so that operators can provide users with more High data rate, lower cost business. [0003] The network architecture of Evolved Universal Terrestrial Radio Ac...
