[0085] figure 1 , figure 2 and image 3 The structures of UE 40, NB 30 and GW 20 according to the first embodiment of the present invention are shown respectively.

[0086] Such as figure 1 As shown in , a radio communication terminal (UE: User Equipment) 40 has: a receiving unit 41 that receives information on a cell of a base station device; a selection unit 42 that selects information on a cell (that is, information assigned to a cell ); and a transmission unit 43 that transmits to the base station apparatus (NB: Node B) 30 information indicating selection of the information on the cell.

[0087] On the other hand, if figure 2 As shown in , the NB 30 has: a receiving unit 31, which receives information indicating a selection of information related to a cell from a UE 40; and a control unit 32, which based on the received information indicating a selection of information related to a cell to grant UE 40 access to NB30. The NB 30 may also have a transmitting unit 33 t...

[0092] refer to Figure 4 The structure of the radio communication system according to this embodiment will be described.

[0093] exist Figure 4 , a radio communication system has a core network node 100 , an RNC 101 , a Node B 102 , an eNB 103 , an H(e)NB GW 200 , an H(e)NB 300 , and a UE 400 .

[0094] Core network node 100 is connected to RNC 101 , eNB 103 and H(e)NB GW 200 .

[0095] RNC 101 is connected to Node B 102 .

[0096] Node B 102 constitutes a macro cell 502 .

[0097] The eNB 103 constitutes an LTE-based macro cell 503 .

[0098] H(e)NB GW 200 is connected to H(e)NB 300 through the Internet.

[0099] H(e)NB 300 constitutes femtocell 501 with CSG ID 50 .

[0100] The UE 400 selects the macro cell 502 or the femto cell 501 as necessary.

[0101] If the macro cell 501 is selected, the UE 400 and the core network node 100 are connected through the Node B 102 and the RNC 101; if the LTE-based macro cell 503 is selected, the UE 400 and the core network node 1...

[0208] Although the structure of this embodiment is basically the same as that of the first embodiment, it is characterized in that H(e)NB 300 and H(e)NB GW 200 are notified of the reason why the user has manually selected a CSG, and if the user has The operation performed by the CSG is selected upon receipt. The operation is Figure 28 shown in .

[0209] exist Figure 28 In , the H(e)NB 300 and the H(e)NB GW 200 of the radio communication system reconfigure the connection target of the UE 400 connected thereto in order to manage radio resources and network resources.

[0210] For example, it is conceivable that the H(e)NB 300 reconfigures the connection target of the UE 400 so as to handover the UE 400 connected thereto to the Node B 102 or the eNB 103 or the like due to insufficient radio resources or insufficient network resources. Neighboring H(e)NB 300.

[0211] Also, it is conceivable that the H(e)NB GW 200 reconfigures the UE's connection target to handover the UE ...

Abstract

A radio communication system according to the present invention includes base station equipment and radio communication terminals. The radio communication terminal selects a cell of the base station device or a cell group to which the cell belongs and transmits information indicating that the cell or the cell group has been selected to the base station device. The base station device receives the information.

Description

technical field [0001] The present invention relates to a radio communication system, a base station device, a radio communication terminal, a gateway device and a communication method. Background technique [0002] In a radio communication system, a user using a UE (User Equipment) sometimes manually selects a name (eg, HNB name) assigned to a cell or a Closed Subscriber Group (hereinafter, CSG: Closed Subscriber Group) assigned to the cell. In this case, the HNB name is text or the like with which the user can easily identify the CSG ID, and when the user selects it, the UE internally interprets the selection of the text as selection of the corresponding CSG ID. [0003] A user may manually select a CSG whether or not it is contained in a CSG list containing those CSGs that are permitted for the UE he or she uses (hereinafter this CSG list is called the allowed CSG list). [0004] If the user selects a CSG that is not included in the allowed CSG list (which contains those...
