Abstract
A mobile station is located and paged for a circuit-switched connection in a GSM system which supports data packet switching (GPRS) services. A table held by the SGSN is provided for locating a mobile station where the mobile has moved from the Routing Area in which it was last located to a cell within the same Location Area which does not support GPRS services. The GSM system comprises a plurality of base station controllers (BSS) serving cells in a Location Area (LA), a circuit-switch control (MSC/VLR) for establishing circuit-switched connections to mobile stations within the Location Area, and a packet control (SGSN) for establishing data packet-switching with mobile stations within one or more Routing Areas (RA) within the Location Area. The packet control, in response to a paging request, consults information from a table held by the packet control of base station controllers which serve cells in the Location Area which are not part of a Routing Area, and instructs base station controllers to page cells in the Location Area and in particular the cells not forming part of a Routing Area.
