  • Patent number: 8718640
    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 (S201); and the HLR triggering a roaming retry process when the mobile station completes location updating in the area covered by the new VMSC/VLR (S203). 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.

  • Patent number: 8712412
    Abstract: The present disclosure relates a method and system for accomplishing a UE purge. The method comprises: a combined node initiates a purge flow of the UE to a HSS to which the UE is attached when determining that a registration state of the UE in all mobility management network elements of the combined node is unregistered and the registration state is not consistent with a registration state of the UE stored in the HSS; wherein the combined node comprises one or more mobility management network elements. The method and system for accomplishing user equipment purge provided by the present disclosure are simple and convenient to implement and effectively solve the technical problem in the prior art.

  • Patent number: 8671161
    Abstract: A method for implementing user registration based on Diameter network protocol comprises: after receiving a network attaching request of a user, a requesting node sending an Update Location Request (ULR) message to HSS of the user, the message including information indicating whether it is necessary to download user subscription data, and also includes information indicating the capability of the requesting node when the downloading is necessary; upon receiving the ULR message, the HSS of the user returning an Update Location Ack message to the requesting node if the check of the user is passed; if the ULR message indicates that it is necessary to download the user subscription data, HSS determining the user subscription data supported by the requesting node according to the information indicating the capability of the requesting node, and including the user subscription data in the Update Location Ack message and then returning it to the requesting node.

  • Patent number: 8284712
    Abstract: The present invention discloses a method for implementing a redirection service for UEs sharing a PUI in an IMS, comprising: when a UE in a PN registers at a PNM AS, the PNM AS fetching the UE Identity and establishing a corresponding relationship between the identity and the PUI; when determining to route an initial request message of a terminating call of a UE in the PN routed by an original S-CSCF to a configured UE sharing the PUI, the PNM AS adding the configured UE Identity into a redirected initial request message and sending it to the original S-CSCF which forwards the message to a redirection S-CSCF; and the redirection S-CSCF uniquely locating the configured UE according to the identity or both the identity and the PUI in the message. The present invention can redirect a session initial request to a configured UE sharing a PUI with other UEs.

  • Publication number: 20120079082
    Abstract: A method for implementing subscription to notification is disclosed in the present invention, which is applied in a user data convergence network including a user data repository. The method comprises: establishing a subscription to notification relationship in the user data repository; said subscription to notification relationship comprises notification triggering condition that describes the condition of the user data repository sending a notification message; when receiving an update data request, if the update data request meets the notification triggering condition, the user data repository sends a notification message to notification event subscriber.
