Abstract:
1. A method for paging a mobile station in a cellular radio access network, the method comprising: wirelessly broadcasting from a first base station a first series of page messages destined to the mobile station, wherein broadcasting the first series of page messages is performed in response to the first base station receiving a paging directive from a control node; determining, by the first base station, a load state of the control node; and responsive to the first base station receiving no response from the mobile station within a defined period after broadcasting the first series of page messages and responsive to determining the load state of the control node, the first base station deciding whether to send a repeat-paging directive from the first base station to a second base station without routing the repeat-paging directive through the control node or rather to route the repeat-paging directive through the control node and then to the second base station, wherein the repeat-paging directive directs the second base station to wirelessly broadcast a second series of page messages destined to the mobile station.
