Patent number: 8359033Abstract: A system and method of supporting packet-switched handover of a mobile station (MS) from a GERAN/UTRAN cell to a Generic Access Network (GAN) cell within a GAN. If the MS is within coverage of the GAN cell, the MS registers within the GAN triggering initiation of the packet-switched handover from the GERAN/UTRAN cell to the GAN cell. A preparation phase is then conducted for executing the packet-switched handover. The preparation phase includes identifying the MS context as part of the preparation phase and activating the GA-PSR TC towards the MS. Next, the packet-switched handover is executed, resulting in the MS switching to GAN mode. The MS then begins transferring packets via the GAN cell. The system and method also supports a packet-switched handover from the GAN cell to the GERAN/UTRAN cell.Type: GrantFiled: June 11, 2007Date of Patent: January 22, 2013Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: John Walter Diachina, Jari Tapio Vikberg, Nils Peter Östrup

Patent number: 7633903Abstract: A method and packet data support node in a radio telecommunications network supporting packet data communication between a packet data network and a mobile terminal in radio communication with a first packet control unit. The packet data support node receives a message from the mobile terminal requesting handover to a second packet control unit. A packet flow context detector in the packet data support node detects the number of packet flow contexts currently active in the first packet control unit for supporting the packet data connection. The detector sends a message during handover to the second packet control unit indicating the number of active packet flow contexts. The message is used for activation of a corresponding number of packet flow contexts in the second packet control unit.Type: GrantFiled: May 10, 2006Date of Patent: December 15, 2009Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Nils Peter Östrup, John Diachina, Gunnar Hedby, Anders Molander, Gunnar Rydnell

Patent number: 7181212Abstract: A radio access network provides information to a mobile radio terminal indicating a list of one or more geographic coverage areas from which the mobile radio terminal may or may not obtain service. In the preferred example embodiment, a “forbidden” list includes one or more geographic coverage areas from which the mobile radio terminal may not obtain service. The mobile checks the received information when considering whether to request service from a new geographic coverage area, and determines whether to select the geographic coverage area depending on that received information. Moreover, the mobile terminal consults that list to determine whether to perform a location area update procedure. In other words, if the list indicates that a new geographic coverage area should not be selected, the mobile terminal does not perform a location area update request in that new coverage area.Type: GrantFiled: August 21, 2001Date of Patent: February 20, 2007Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: William Damian Hogan, Nils Peter Ostrup

Patent number: 7093010Abstract: A flexible consistency checking mechanism allows network operators to create their own consistency checking rules. Several consistency check formulas are provided. Each formula defines one or more general operations on one or more managed network objects. By applying a general consistency check formulas to one or more specific managed network objects, one or more consistency check rules is generated. For example, the user can generate the consistency check rules simply by inputting certain data values for formula variables by way of a user interface. Once those rules have been generated, they can be used to check the consistency of one or more aspects of a communications network configuration. Each formula also may include a checkpoint that defines a time period or event when a corresponding consistency check rule established using that formula should be executed.Type: GrantFiled: May 20, 2002Date of Patent: August 15, 2006Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Nils Peter Ostrup, Jesper Hök

Patent number: 6711405Abstract: There is described a method of detecting faults on an uplink control channel, such as an access channel. More specifically, a base station, or other network infrastructure component with a receiver for access requests, is provided with a separate receiver, which is adapted to detect and count access messages. The counted number of access messages is then compared with the number of access messages received by the first receiver. If the number of accesses received by the two receivers are significantly different, this may indicate a fault in the access channel.Type: GrantFiled: April 16, 2001Date of Patent: March 23, 2004Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Nils Peter Östrup, Per Johan Schultz

Publication number: 20030040314Abstract: A connection is established between a mobile radio terminal and a radio access network serving plural geographic coverage areas. The radio access network transmits information associated with one of the geographic coverage areas indicating whether the one geographic coverage area requires a geographic coverage area update procedure. During the connection, when the mobile radio terminal considers selecting the one geographic coverage area, it determines whether to perform a geographic coverage area update procedure depending on the transmitted information associated with the one geographic coverage area.Type: ApplicationFiled: January 16, 2002Publication date: February 27, 2003Applicant: Telefonaktiebolaget LM EricssonInventors: William Damian Hogan, Nils Peter Ostrup

Patent number: 6230017Abstract: In a cellular telecommunications network, geographical restriction is stored for a mobile subscriber in the subscriber's record (100A, 100B, 100C, 100D) in a database at a node of the network, preferably at a home location register [HLR] (24). In accordance with one mode of the invention, the mobile station is permitted to operate only in cells identified in the subscriber's record in the HLR. In accordance with this mode, only applicable cells listed in the subscriber's record are paged when a call is direct to the mobile station, and the mobile station can only originate calls and sustain calls from such cells. In a variation of this mode, calls originated by the mobile station in the applicable cells listed in the subscriber's record can be sustained when the mobile station travels into non-applicable cells. In accordance with another mode known as “soft” restriction, a first (e.g.Type: GrantFiled: August 22, 1997Date of Patent: May 8, 2001Assignee: Telefonaktiebolaget LM EricssonInventors: Mikael Andersson, Nils Peter Östrup, Kjell Anders Westroos

Patent number: 6205336Abstract: A hierarchically structured cellular network is disclosed. When an active mobile station requests a service that requires the use of a network resource not available in the cell handling the ongoing call (or, alternatively, during call set up), the network checks for cells on the higher levels to determine if the required resource is available. If the resource is available in a higher level cell, the call is handed over to that cell and the resource is allocated to the call. The call can be maintained in the higher level cell until the resource is no longer needed, or a “better” cell capable of providing the required resource is found.Type: GrantFiled: August 14, 1998Date of Patent: March 20, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Nils Peter Östrup, Per Johan Schultz, Lars Folke Johansson, Lars Håkan Palm
