- the UE when the user selects a CSG by manual selection, the UE makes a connection request message with a parameter or Cause value indicating that the user is requesting connection to the manually selected CSG, H (e) Send to NB. Also, the H (e) NB transmits, to the H (e) NB GW, a UE Register Request message in which a parameter indicating that the user has made a connection request to the manually selected cell or a Cause value is set.
- the access control in the H (e) NB and the H (e) NB GW is invalidated, the access control of the UE can only be performed in the Core Network Node. In this case, even if the access control of the UE, such as an incorrect operation or an installation error, fails in the Core Network Node, the connection request can be repeatedly and repeatedly made from the UE. In that case, the access can not be denied in the H (e) NB and the H (e) NB GW, and the load of access control processing in the Core Network Node increases. Furthermore, if there are a large number of such UEs, the load increase of the Core Network Node may cause a system down due to overload of the Core Network Node.
- UE which makes connection impossible by access control of UE by Core Network Node is registered into the blacklist of UE which H (e) NB and H (e) NB GW hold
- H (e) NB and H (e) NB GW in access control, reject the connection request of the UE if the source UE of the connection request message is a UE that is included in the blacklist.
- H (e) NB and H (e) NB GW are wide or if H (e) NB and H (e) NB GW are installed in a place where many users gather. It is expected that the number of UEs registered in the blacklist will be very large. As a result, an increase in the required memory area may cause a memory shortage, and an increase in processing load may cause a shortage of processing capacity. Furthermore, when the number of such UEs is very large, the memory load increase of H (e) NB and H (e) NB GW, and the effect of processing load increase may be the excess of H (e) NB and H (e) NB GW. It may cause system down due to load.
- the blacklists of UEs held in the H (e) NB and the H (e) NB GW are for each UE.
- the valid time timer and the maximum number of registrable UEs are set.
- the UE is deleted from the blacklist when the valid time timer prepared for the UE expires.
- the maximum number of UEs is registered in the blacklist, the oldest UE registered in the blacklist is deleted, and the latest UE is registered in the blacklist.
- H (e) NB and H (e) NB GW saving of memory usage in H (e) NB and H (e) NB GW and reduction of processing load are possible.
- the UE in the relocation process of connection control in H (e) NB and H (e) NB GW, the UE is allowed to stay in the cell of the selected CSG, or a neighbor cell having the same CSG ID as that cell. Allow only movement to
- the UE can be moved to a CSG or a macro cell different from the CSG desired by the user since the UE can be connected to the CSG desired by the user, and as a result, the CSG or CSG different from the CSG desired by the user It is possible to avoid staying in the macro cell.
- the UE when the user manually selects a macro cell by the user and the UE makes a connection request to the RNC or eNB via the Node B, the macro cell manually selected by the user Notify that you are requesting a connection. Furthermore, in the connection control relocation process in the Node B and the RNC or eNB, the UE may remain in the selected macro cell or may only move to a neighboring macro cell.
- the UE can be moved to the H (e) NB of the CSG because the UE can be connected to the macrocell desired by the user instead of the femtocell of the CSG not desired by the user. It is possible to avoid staying in the femtocell of H (e) NB of CSG different from the macrocell desired by the user.

- the H (e) NB GW 200 receives a new parameter “Manual CSG ID Selection” indicating that manual selection has been made in HNBAP: UE Register Request message received from the H (e) NB 300, even if It is possible to perform access control of the UE 400.
- the H (e) NB 300 receives the HNBAP: UE Register Reject message from the H (e) NB GW 200.
- the rejection reason at that time is a value that means that the CSG selected by Manual CSG ID Selection can not be used (for example, Selected CSG not Allowed).
- the H (e) NB GW 200 determines permission of connection using the UE blacklist registration memory 2006, but if the UE-CSG relation registration data 1005 can be confirmed, the CSG to which the UE 400 is connected is the UE. It is also possible to determine the permission of connection by confirming whether the permission is permitted in the CSG relation registration data 1005.
- the H (e) NB 300 performs the following process when receiving the HNBAP: UE Registrer Reject message from the H (e) NB GW 200. 1) If the rejection reason is Selected CSG not Allowed, the UE 400 is updated so as to be retained in the UE blacklist registration memory 3006, and release processing of the UE 400 is performed. 2) If the rejection reason is not Selected CSG not Allowed, only the release process of the UE 400 is performed.
- the H (e) NB 300 performs the following processing when receiving RANAP: Iu Release Command from the Core Network Node 100. 1) When the Release Cause is a value that means that the CSG selected by Manual CSG ID Selection is not available (for example, Selected CSG not Allowed), the UE 400 is updated to be retained in the UE blacklist registration memory 3006 , Release the UE 400. 2) When Release Cause is other than Selected CSG not Allowed, only the release process of the UE 400 is performed.
- H (e) NB300 invalidates the access control in H (e) NB300 even if Indicator "Manual CSG ID Selection" indicating that manual selection is made to RRC Connection Request message from UE400 is set. It is possible to realize that it is effective. Therefore, access control is performed in the H (e) NB 300 for the connection request of the UE 400 such as an incorrect or implementation error, and the load of access control in the H (e) NB GW 200 and the load of access control in the Core Network Node 100 Can be reduced.
