A method for reducing communications with, and signalling to and from, an HLR (204) is disclosed for local or MSC-originated calls (118). When a subscriber registers (114) with the HLR (204), the complete profile for that subscriber is transferred (116) to the VLR (207) associated with the MSC (206) (or MSC/WOS) involved. When a call (118) to the subscriber is originated in the MSC (206), the VLR (207) associated with that MSC (206) is checked (102) to determine if the subscriber's location information is already maintained in the VLR (207). If so, the MSC (206) can page (122) and route the call to the subscriber's mobile phone via (222) the base station transmitter (210, 212, 214) associated with the VLR (207). As such, for such local MSC-originated calls (118), there is no need to interrogate the HLR (204) for subscriber information, thus reducing signalling to and from the HLR (204). |
