Problems solved by technology

[0020] However, if the source HeNB is a hybrid mode HeNB, the following problem exists in the judgment process B in step 203: when the working mode of the source HeNB is a hybrid mode, the UE can access in either a closed mode or an open mode; however , the HeNB GW cannot determine how the UE accesses the source HeNB. Therefore, even if the source HeNB and the target HeNB belong to the same CSG, the HeNB GW still cannot accurately determine how the UE accesses the target eNB and whether it can connect The CSG to which the target HeNB belongs, that is, the CSG to which the source HeNB belongs, makes the HeNB GW unable to effectively complete the auxiliary access control judgment, and still needs the CN to make the access control judgment, so that the superiority of the auxiliary access control judgment of the HeNB GW is obtained. less than play

Embodiment 1

[0056] During the UE's initial access to the HeNB, the HeNB GW obtains the UE's access mode in the mixed-mode HeNB by reading the initial context establishment message sent by the CN to the HeNB. The specific processing process is shown in 3:

[0057] Step 301: A corresponding RRC connection is established between UE and HeNB.

[0058] Step 302: After the RRC connection is established, the UE sends an RRC connection establishment complete message to the HeNB, and the RRC connection establishment complete message includes a NAS initialization message (such as an Attach request).

[0059] Step 303: After receiving the RRC connection establishment completion message, the HeNB sends an initialization UE message to the CN through the HeNB GW. The initialization UE message includes the UE unique identifier (such as IMSI), NAS initialization message, and HeNB related parameters. The HeNB related parameters are as follows: CSG identifier, access mode (Access Mode) (such as open mode, ...

Embodiment 2

[0067] During the handover process, the source HeNB provides the UE access mode in the source HeNB to the HeNB GW through the handover request message, and the specific processing process is shown in 4:

[0068] Step 401: UE measures the signal of the target HeNB, and reports the measurement result to the source HeNB; the source HeNB makes a handover decision according to the received measurement result.

[0069] Step 402: The source HeNB determines to perform inter-HeNB handover, initiates a handover request to the connected HeNB GW, and sends a handover request message including parameters such as S1AP signaling link identifier, target cell identifier, and source-to-target transparent container; For inter-HeNB handover, the handover request message should also include parameters such as the target HeNB’s CSG identity and access mode; if the source HeNB is a mixed-mode HeNB, the handover request message should also include the UE’s access mode in the source HeNB , the source ...

Embodiment 3

[0086] During the initial access process of the UE, the CN stores the access mode of the UE in the HeNB. Therefore, during the handover process, the HeNB GW determines that the source HeNB and the target HeNB belong to the same CSG, and the source HeNB is a hybrid mode HeNB. At this time, the HeNB The GW cannot determine the UE's access mode in the hybrid mode HeNB, and the HeNB GW queries the CN about the UE's access mode in the source HeNB. The specific processing process is shown in 5:

[0087] Step 501: UE measures the signal of the target HeNB, and reports the measurement result to the source HeNB; the source HeNB makes a handover decision according to the received measurement result.

[0088] Step 502: The source HeNB determines to perform inter-HeNB handover, initiates a handover request to the connected HeNB GW, and sends a handover request message including parameters such as S1AP signaling link identifier, target cell identifier, and source-to-target transparent conta...

Abstract

The invention discloses a method and a device for implementing auxiliary access control judgment. In the scheme of the invention, a base station gateway acquires an access mode of User Equipment (UE) in a mixed mode base station, and auxiliary access control judgment is performed according to the access mode of the UE in the mixed mode base station. Therefore, the problem that the base station gateway cannot judge whether the UE can be accessed to a target base station when the UE is switched between the base stations in the base station gateway is solved by the scheme of the invention. Because the base station gateway can acquire the access mode of the UE in the mixed mode base station, the base station gateway can effectively assist the access control judgment, the corresponding switching flow can be finished in the base station gateway, the purpose of auxiliary access control judgment is really fulfilled, signaling interaction between the base station gateway and a communicating net (CN) and system load are reduced, the capability judgment of the CN on accessing the UE to a CSG is reduced, and the superiority of the auxiliary access control judgment is fully exerted.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for realizing auxiliary access control judgment. Background technique [0002] The evolved home base station (HeNB, Home eNodeB) is a small, low-power base station, which is mainly deployed in indoor places such as homes and offices. costs, while making up for the lack of coverage of existing distributed cellular wireless communication systems. HeNB has the advantages of affordability, convenience, low power output, and plug-and-play. [0003] The HeNB can be connected to the core network (CN, Core Network) through the logical network element Home NodeB Gateway (HeNB GW, Home eNodeB Gateway), such as figure 1 As shown, the HeNB GW is mainly used to verify the security of the HeNB, perform operation and maintenance management on the HeNB, configure and control the HeNB according to the requirements of the operator, and be responsible for the data interaction...
