Abstract
A method for triggering a roaming retry and a home location register (HLR) are provided. The method is applied to a situation that a mobile station (MS) moves from an original Visitor Mobile Switching Center (VMSC)/Visitor Location Register (VLR) to an area covered by a new VMSC/VLR. The method comprises: the HLR receiving a location updating request message from the mobile station through the new VMSC/VLR when requesting for allocating a roaming number or providing subscriber information (S); and the HLR triggering a roaming retry process when the mobile station completes location updating in the area covered by the new VMSC/VLR (S). The technical solution above solves the problem of Pre-paging failure in the related art, which is caused when a called user roams simultaneously out of the local location area during the pre-paging.
