<p>The invention provides a method and a device for transmitting closed subscriber group (CSG) information so as to support paging optimization. The method and the device only transmit the changed CSG information among network entities by combining the access control of the CSG in long term evolution (LTE) and a network frame of an LTE home enode base station (HeNB), so that the data transfer among the network entities is reduced and the cell needing paging can be comprehensively judged by a mobility management entity (MME) with tracking area (TA) information and CSG information so as to prevent redundant paging and reduce the waste of the wire and wireless transmission resource. In addition, the invention also provides a collocation method for a tracking area mark for further optimizing the paging; and the method prevents unnecessary paging from being initiated in a macro cell caused by the paging at a home cell through reasonable collocation of the tracking area mark so as to reduce the waste of the air interface resource of the macro cell. The method and the device can support the paging optimization in the LTE and a further evolution network thereof and effectively support the large-scale deployment and mobility management of the HeNB.</p> |
