Patent number: 6009322Abstract: A method in a telecommunications network having a configuration management system, of automatically populating a Private Numbering Plan (PNP) subscription with PNP data. The method begins by defining a group comprising a plurality of members who subscribe to a PNP service, and automatically generating the PNP data for each of the plurality of group members when the group is defined. The PNP data may be generated by service management application software in the configuration management system. The PNP data may include in abbreviated number for each of the plurality of group members. The abbreviated numbers may be generated by several methods including incremental number generation, random number generation, or by extracting the last "X" digits of each group member's telephone number. The method then determines whether each generated abbreviated number is valid and unique. A network operator may override an automatically generated number by manually inputting an abbreviated number which is valid and unique.Type: GrantFiled: July 21, 1997Date of Patent: December 28, 1999Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Jim Dumont

Patent number: 5999814Abstract: A method of handling oscillating mobile station handoffs between cells in a cellular telecommunications network. The method comprises the steps of detecting whether a mobile station (MS) is exhibiting an oscillating handoff pattern, determining whether the MS's signal strength with the MS's serving cell is above a safe signal strength threshold, and inhibiting handoffs of the MS upon determining that the signal strength is above the safe signal strength threshold. The oscillating handoff pattern is detected by first detecting a sequence of handoffs of the MS in which the number of handoffs is twice the number of cells involved in the handoffs, measuring an inter-handoff time period between each handoff in the sequence, and determining whether each inter-handoff time period is less than a first threshold value.Type: GrantFiled: May 5, 1998Date of Patent: December 7, 1999Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Angelo Cuffaro, Mahshid Izady

Patent number: 5995848Abstract: A method and system of completing calls to busy mobile subscribers in a radio telecommunications network. The system includes a gateway mobile switching center (G-MSC) to provide switching functions to a mobile station (MS) in a home service area, a home location register (HLR) providing a location of the MS to the G-MSC, a visitor mobile switching center (V-MSC) to provide switching functions to the MS when the MS roams outside the home service area, and a service control point (SCP) which includes service logic for periodically initiating a call attempt to the MS to determine if the MS is busy. When the calling party attempts to call a busy MS, the calling party may request an automatic callback service. The G-MSC releases all trunks from the calling party and the MS and notifies the SCP. The SCP periodically initiates a call attempt to ascertain whether the MS is idle. Upon determining that the MS is idle, the G-MSC connects the call between the calling party and the MS.Type: GrantFiled: July 21, 1997Date of Patent: November 30, 1999Assignee: Telefonaktiebolaget LM EricssonInventor: Viet Anh Nguyen

Patent number: 5983095Abstract: A system and method in a radio telecommunications network of utilizing a plurality of telephone numbers with a single mobile telephone by changes to the network rather than the mobile telephone are disclosed. The system provides a mobile subscriber with an indication of the directory number dialed by the calling party. A plurality of directory numbers, a plurality of mobile identification numbers (MINs), and a plurality of alpha-numeric strings are stored in a database in the network such as a home location register (HLR). Several directory numbers are associated with the mobile telephone's MIN, and then each directory number is associated with an alpha-numeric string. When a directory number is dialed, an associated MIN and alpha-numeric string are identified. The MIN and alpha-numeric string are then transported through the network to the mobile telephone while the mobile telephone is being alerted.Type: GrantFiled: July 26, 1996Date of Patent: November 9, 1999Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Duncan Peter Craig Cameron

Patent number: 5978670Abstract: A system for reducing fraudulent use of a mobile telephone number in a radio telecommunications network. The system automatically bars call originations from the mobile telephone if the mobile telephone does not register with the network for a predetermined time period, or if the mobile telephone does not originate a call for a second predetermined time period. The system determines when a mobile telephone originates a call, measures a predetermined time period with a timing mechanism, and starts the timing mechanism when the mobile telephone originates a first call. The system then determines whether a second call originated from the mobile telephone during the predetermined time period and restarts the timing mechanism at the time that the mobile telephone originates a second call upon determining that the second call originated from the mobile telephone during the predetermined time period.Type: GrantFiled: May 6, 1996Date of Patent: November 2, 1999Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Stefano Casoli, Allan Benjamin Ewart, David Spies, Ghassan Assi

Patent number: 5960338Abstract: A system and method in a radio telecommunications network having a home location register (HLR) and a serving mobile switching center (MSC) of preventing fraudulent long distance calls from a subscriber's mobile station by selectively barring the mobile station from accessing the network when an indication of fraud exists. The system sends from the serving MSC to the HLR, an indication of a long distance call origination from the subscriber's mobile station, starts a timer, increments a counter which counts long distance call originations, and determines whether the number of long distance call originations exceeds a predetermined threshold. The system allows the long distance call upon determining that the number of long distance call originations does not exceed the predetermined threshold. The system further determines whether a time period threshold has been exceeded, upon determining that the number of long distance call originations exceeds the predetermined threshold.Type: GrantFiled: September 27, 1996Date of Patent: September 28, 1999Assignee: Telefonaktiebolaget LM EricssonInventor: George Foti

Patent number: 5951035Abstract: The trailer hitch alignment system of the present invention includes an alerting device and a tow bar assembly for attachment to a towing vehicle. The tow bar assembly includes a photoelectric sensor for detecting the vertical alignment of a trailer tongue. The tow bar assembly has a hitch ball with a spherical top and a cylindrical body for coupling with a trailer tongue having a semi-spherical socket. In one embodiment, the photoelectric sensor is mounted on the tow bar of the tow bar assembly, adjacent to the hitch ball. In another embodiment, the hitch ball houses the photoelectric sensor within its interior. During operation, the driver of the towing vehicle typically maneuvers the vehicle toward the trailer in a rearward direction. Once the photoelectric sensor detects the vertical alignment of the socket with the ball, the alerting device is activated informing the driver of the alignment.Type: GrantFiled: March 11, 1997Date of Patent: September 14, 1999Inventors: Robert E.

Patent number: 5933777Abstract: A method and system for allocating channel elements in a code division multiple access (CDMA) radio telecommunications network is disclosed. The method begins by a contribution assessor determining a candidate set of base stations having sufficient signal strength with the entering mobile station to establish a voice channel. Next, the contribution assessor measures the signal strength between each base station of the candidate set of base stations and the operating mobile stations served by each of the base stations. The contribution assessor determines which base station of the candidate set of base stations has the weakest signal strength with one of its served operating mobile stations. Then, a load processor reallocates a channel element away from the mobile station having the weakest signal strength to the entering mobile station.Type: GrantFiled: April 24, 1997Date of Patent: August 3, 1999Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Mohamed Anisur Rahman
