The present invention relates to a paging method and system for a radio access network which provides access to a core network, said system comprising a central network controlling device (100) for receiving pagings and for distributing said pagings to other network controlling devices (5) based on a paging information provided to said central network controlling device. Accordingly, while the access network comprises many RNCs and/or RNASs, the information required for paging or mobility management is provided at one place in one location or routing area. Thus, when the core network sends a paging request, the request does not have to be transmitted to many RNCs and/or RNASs and extra paging can be avoided in the access networks. Moreover, a paging coordination is possible despite of the number of different core networks.
