Problems solved by technology

Therefore, when the core network performs access control on the HNB under the home base station gateway, it can only rely on the information reported by the UE. When the UE does not report honestly, it will cause the above security risks

Embodiment 1

[0064] This embodiment takes Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) as an example, the source network element is RNC, the UE resides in the macro cell M1, and the CSG cell to be handed over by the UE is H1.

[0065] In UMTS, when the UE measures that the CSG cell H1 meets the handover threshold, the UE sends a measurement report to the base station, and the base station forwards the measurement report to the serving RNC. The measurement report includes the Cell ID of the CSG cell H1 and the target home base station to which the cell H1 belongs. The CSG ID. After the RNC receives the measurement report, it decides to initiate a handover to the HNB. The RNC sends a UE handover request (HandoverRequired) message to the core network, and the UE handover request message includes the Cell ID of the CSG cell H1 and the CSG ID of the target HNB to which the cell H1 belongs. After the core network receives the handover request fro...

Embodiment 2

[0067] This embodiment takes a Long Term Evolution (LTE, Long Term Evolution) system as an example, the source network element is an eNB, the UE resides in the macro cell M1, and the target cell to be handed over by the UE is H1.

[0068] In the LTE system, when the UE measures that the CSG cell H1 meets the handover threshold, the UE sends a measurement report to the serving eNB, and the measurement report includes the CellID of the target cell H1 and the CSG ID of the target HNB to which the cell H1 belongs. After receiving the measurement report, the eNB decides to initiate a handover to the HNB. The eNB sends a UE handover request message to the core network, and the UE handover request message includes the Cell ID of the target cell H1 and the CSG ID of the target HNB to which the cell H1 belongs. After the core network receives the UE handover request message, it searches the white list corresponding to the UE stored on the core network side according to the CSG ID conta...

Embodiment 3

[0070] This embodiment takes the LTE system as an example, the source network element is the HeNB, the UE resides in the CSG cell H1, and the target cell to be handed over by the UE is H2.

[0071] In the LTE system, the HeNB where the CSG cell H1 is located is directly connected to the core network. When the UE measures that the CSG cell H2 meets the handover threshold, the UE sends a measurement report to the serving HeNB where H1 is located, and the measurement report includes the Cell ID of the CSG cell H2 and the CSGID of the target HNB to which the cell H2 belongs. After the HeNB receives the measurement report, it decides to initiate a handover to the HNB. The HeNB sends a UE handover request message to the core network, and the UE handover request message includes the Cell ID of the CSG cell H2 and the CSG ID of the target HNB to which the cell H2 belongs. After the core network receives the UE handover request message, it searches the white list corresponding to the ...

Abstract

The invention provides a method for controlling access of a network during switching of a Home Node B, which comprises the following steps that: a core network acquires a targeted Home Node B message to determine whether to allow the access of the user equipment (UE); when the access of the UE is allowed and the Home Node B is connected with the core network by a Home Node B gateway, the core network sends the targeted Home Node B message to the Home Node B gateway to which the Home Node B belongs; and the Home Node B gateway determines whether to allow the access of the UE according to the received targeted Home Node B message. The invention also provided a system for controlling access of the network during switching of the Home Node B. By adding a UE access control into the Home Node B gateway, when the UE enters the Home Node B cells by switching, the Home Node B gateway verifies the access control message (reported to the core network) of the UE by the Home Node B gateway, so the occurrence of illegal access incident is prevented, and the security of network access is improved.

Description

technical field [0001] The present invention relates to network access control technology, in particular to a method and system for network access control when a home base station (HNB, Home NodeB) switches. Background technique [0002] HNB is a small, low-power base station, which is installed in indoor places such as homes and offices. Insufficient coverage of wireless communication systems. The advantages of HNB are affordable, convenient, low power output, plug and play, etc. [0003] figure 1 is a schematic diagram of the HNB network topology, such as figure 1 As shown, the HNB and the Home Node B Gateway (HNBGW, Home Node B Gateway) together form a Home Node B Access Network (HNB AN, Home NodeB Access Network), and HNB users are connected to the core network through the HNB AN. Among them, the main functions of HNB GW are: verifying the security of HNB, processing HNB registration and HNB access control, operating and maintaining HNB, configuring and controlling t...
