  • Patent number: 6314284
    Abstract: A telecommunications system and method is disclosed for providing service transparency for mobile terminating calls to a roaming H.323 mobile terminal. An H.323 mobile terminal can be assigned both an office number and a regular Mobile Station Integrated Services Digital Network (MSISDN) number. The MSISDN of the H.323 mobile terminal will not be made available to the H.323 mobile subscriber or to anyone else. The MSISDN will only be used internally within the Public Land Mobile Network (PLMN) and H.323 system to route the call properly. Thus, whenever a call attempt is made to the H.323 mobile terminal, the call shall always be routed to the H.323 Gatekeeper. If the H.323 mobile terminal has roamed outside the H.323 network, the H.323 Gatekeeper can apply mobile terminating services to the incoming call and route the call to the serving PLMN of the H.323 mobile terminal using the H.323 mobile terminal's MSISDN.

  • Patent number: 6289223
    Abstract: A system and method in a telecommunications system for enabling an originating mobile unit to deliver SMS messages to a select plurality of destination mobile units. A mobile station ISDN number (MSISDN) is assigned to a usergroup wherein this usergroup contains at least one and preferably a plurality of member MSISDNs. An originating mobile unit may then transmit an SMS message to a plurality of destination units by transmitting an SMS message addressed to a predefined usergroup MSISDN thereby eliminating the necessity of the originating mobile unit addressing and transmitting the SMS message to each member of the defined usergroup. Allowances are made to restrict such transmission to specified originating units.

  • Patent number: 6081731
    Abstract: Selective carrier denial in a cellular system restricts some or all carrier-handled calls from a given cellular subscriber while simultaneously allowing other cellular calls. A restriction flag or indicator in a Visitor Location Register (VLR) of the cellular system is set by a Home Location Register (HLR) which contains a list of those carriers denied to subscribers. When the restriction flag is set, the HLR is interrogated to determine if the call is restricted. Alternatively, the restriction flag may reside within the subscriber's mobile phone. Further, the VLR or mobile phone may, respectively, contain a list of denied carriers and internally determine if carrier denial applies without resort to the HLR.

  • Patent number: 6049714
    Abstract: A telecommunications system and method for routing a phone call when the switch serving the caller cannot access a database is disclosed. The system includes a switch serving mobile stations, a node for receiving information from the switch and for determining whether or not the telephone call terminates at a mobile station, a database for sending information when the telephone call terminates at a mobile station and a second database for sending information when the telephone call does not terminate at a mobile station. The method involves receiving the telephone call at a switch serving mobile stations sending information pertaining to the telephone call to a node, determining whether the telephone call terminates at a mobile station, when the telephone call does terminate at a mobile station, accessing one database, and when the call does not terminate at a mobile station, accessing a second database.

  • Patent number: 6047056
    Abstract: A system and method for suppressing redundant database queries between two switching points in a telecommunications system, where the switching points are unable to utilize the ISUP communications protocol. The system and method are implemented by using a parameter of the communications protocol to indicate whether a database query has been performed. When the receiving switch receives the information, the switch is suppressed from performing a redundant database query by the parameter of the communications protocol.

  • Patent number: 5884179
    Abstract: A call setup signal is routed to the gateway mobile switching center (GMSC) serving a public land mobile network (PLMN) associated with a called mobile station. The GMSC then sends a signal including data identifying the originating switch to the home location register (HLR) associated with the called mobile station. Upon determining that it would be more efficient and direct for the originating switch to release the first call connection to the GMSC and to re-originate a new call setup signal directly towards the mobile switching center (MSC) currently serving the called mobile station, the HLR transmits a Mobile Application Part (MAP) based signal to the originating switch. As a result, the originating switch releases the original call connection and re-originates a call setup signal using a roaming number identifying the MSC currently serving the mobile station as a destination address.

  • Patent number: 5878115
    Abstract: A routing address representing an alternative terminal is assigned to a particular service area. Such a service area comprises a Local Access and Transport Area (LATA), Mobile Switching Center (MSC) area, Location Area, and Cell Area. Whenever an incoming call is received towards a mobile station currently located within the particular service area, instead of transmitting a routing address representing the mobile station, the serving mobile switching center (MSC) transmits a signal containing the routing address representing the alternative terminal. Instead of routing the call to the intended mobile station, the gateway mobile switching center (GMSC) utilizes the received routing address and reroutes the incoming call to the alternative terminal. By rerouting all incoming calls towards the alternative terminal in case of an emergency, all available access channels are reserved for making outgoing calls by the mobile subscribers located within the emergency service area.

  • Patent number: 5878347
    Abstract: Incoming calls or messages for a mobile station that has been ported from a first HLR to a second HLR are first received by a gateway node. The gateway node, in turn, transmits a signal requesting routing instruction to a centralized database connected to a gateway node. Utilizing the received Mobile Station Integrated Services Digital Network (MSISDN) number, the centralized database determines the network address of the new HLR currently serving the ported mobile station. The received signal requesting routing information is then routed to the new HLR. The new HLR retrieves the requested information and transmits it back to the gateway node. The gateway node, utilizing the received routing information received from the new HLR, accordingly routes the incoming calls or messages to the ported mobile station.

  • Patent number: 5835856
    Abstract: User defined or entered text messages are transported from a mobile station to the serving mobile switching center (MSC) over a connection-less communications link. An application module within the serving MSC extracts the encapsulated user defined text messages from the received signal for forwarding to the associated billing center. The billing center, after consolidating the call data received by a Toll Ticket, produces billing statements containing the user defined text messages allowing mobile subscribers to better identify and keep record of each call.

  • Patent number: 5456919
    Abstract: A tamper-resistant dosage form capsule for the oral administration of therapeutic agents comprises a two-part capsule which is shrunk around a caplet so that the outer wall of the caplet is bound to the inner walls of both parts of the capsule. The caplet is placed into the capsule, and the dosage form is then subjected to relatively high humidity and temperature conditions, followed by drying the dosage form in a lower humidity environment, so that the capsule is shrunk to conform to the contours of the caplet and both parts of the capsule are bonded to the caplet.
