  • Patent number: 7058413
    Abstract: A multicast management mechanism for mobile networks. The mechanism proposes a multicast table approach to considerably reduce the number of short messages and multimedia messages sent to a service area, thereby reducing its paging cost. The multicast management mechanism for mobile networks includes the steps: establishing a VLR recorder table in a home location register (HLR), to record VLR addresses located by multicast users and the total number of multicast users in each VLR; and establishing LA tables, to record LA addresses in each VLR and the total number of multicast users in each LA.

  • Publication number: 20040033811
    Abstract: The present invention relates to a messaging management system and method for users roaming in a multi-campus enterprise mobile communication environment, wherein the voice messaging is transported only on demand so as to reduce the bandwidth requirement for the digital data network to lower the enterprise's operation cost, and a Voice Messaging System Call-Back (VMS Call-Back) is provided to render the present invention as a user friendly system so as to prevent the users from the problem of uncertain waiting time when the users listen to the voice messages which are transported among different campuses. The system and method of the present invention not only significantly lower the unnecessary transport of the voice messaging but also can operate under the condition of insufficient digital data network bandwidth, which can reduce the cost for network bandwidth and loosen up the operation requirements for the voice messaging system.

  • Patent number: 6243457
    Abstract: The basic philosophy of Intelligent Network (IN) is the separation of service control from the telephone switches which now perform only connection control and a minimum amount of work to facilitate service control. In IN terms, Service Control Point (SCP) determined how a particular call from a user is routed and how to manipulated it once a call is set up and some interesting events happen. The telephone switch with the added IN capabilities o collaborate with the SCP in IN services is called Service Switching Point (SSP). All the services will be managed by Service Management System (SMS). For the management of IN, the Telecommunication Management Network (TMN) is adopted, all the management information are defined as managed objects and transmitted within the management network. An Q Adaptor is a software process and responsible for the maintenance of the MIB tree and the management information conversion between SMS and SCP.

  • Patent number: 6078811
    Abstract: A mobile communication system is disclosed including one or more home location registers, one or more visitor location registers and one or more mobile terminal equipments. Each mobile terminal equipment is served by a single home location register. Each registration area or geographical area of mobile communication service is covered or served by a visitor location register. "Overflow" mobile terminals, i.e., more mobile terminals than user records that can be maintained at the visitor location registers, are permitted to register at the visitor location registers. To that end, each home location register maintains an indication, e.g., a bit, for each mobile terminal it manages indicating whether or not the mobile terminal is an overflow mobile termninal. When a mobile terminal is registered at the visitor location register and no user records are available, the visitor location record nevertheless registers the mobile terminal.
