The invention discloses a method for reporting a measuring report of a CSG cell, which can quicken the process of switching to the CSG cell. The method comprises that when discovering that an adjacent CSG cell is a usable adjacent CSG cell in the measuring process, user equipment UE in a connected state immediately reports the measurement report containing the CSG cell to a network side.

The method involves storing information related to a private base station and neighboring public cells by an user equipment (UE). Several private cells provided adjacent to the private base station are determined by the user equipment such that the cells adjacent to the private base station are provided with access rights. The private cell reselection search is performed by the user equipment, when the user equipment is in proximity to the private base station.

The embodiment of the invention discloses a method and network equipment for controlling users to access. The method comprises the following steps: receiving an access request message which contains the closed user group (CSG) ID of a cell to be accessed by the user; determining whether the number of current users who access the access network of the cell through the CSG ID, reaches the upper limit of the user number; and controlling the access of the users according to the determined result.

The invention discloses a method and a system for handling failure of closed user group cell switching. In the invention, when user equipment (UE) is not the authorized user of a target content service gateway (CSG) cell, a core network notifies a source base station or a source radio network controller (RNC) of the failure information of a non-member, so that the UE is forced to update an allowed CSG list to stop the source base station or the source RNC from further sending a switching request to the same target cell, or a delay timer is configured in the source base station or the source RNC to wait for the updating of the CSG list of the UE so as to stop the UE from frequently sending the switching request to the same target cell, or the source base station or the source RNC forbids the UE switching to an adjacent CSG cell with the same CSG identification (ID) under the condition that the CSG ID of the target CSG cell can be acquired. In the invention, after UE switching fails, the method and the system can prevent the source base station or the source RNC from sending the switching request to the same target CSG cell again, so that signal consumption between interfaces is reduced and network performance is improved.

The method can realize that the user terminal is accessed into the closed user group cell under the connection status.

An arrangement for providing, on an ad hoc basis, closed user group (CUG) among a collection of pre-defined IP network users. A set of intelligent access devices, dispersed through the IP network, constantly transmit a set of pings associated with the defined CUGs to discover those devices within its communication range. The discovered IP addresses for each device is thus constantly updated, allowing group members to remain in constant contact (emulating an “always on” connection). The users feel they are always connected with group members and thus have instant access to voice/data/video sessions—much like hot lines or “always on” connections.
