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

Publication number: 20060171369Abstract: A multimedia broadcast multicast type service (MBMS) is offered to mobile subscribers. A RAN node communicates with one or more radio base stations that transmit and receive information with mobile subscriber terminals, some of which subscribe to the MBMS. The RAN node communicates with multiple core network packet data nodes that receive MBMS data for delivery to the RAN node. One of the multiple core network packet data nodes is selected to provide the MBMS data associated with the MBMS to the RAN node. The others are instructed not to provide the MBMS data, but they still perform other MBMS support functions for their mobile terminals such as MBMS charging, etc.Type: ApplicationFiled: February 3, 2005Publication date: August 3, 2006Applicant: TELEFONAKTIEBOLAGET L M ERICSSON (Publ)Inventors: Peter Ostrup, Jens Bergqvist

Patent number: 6731944Abstract: An apparatus and method are provided that can effectively improve a paging scheme of a traditional cellular system. Basically, the apparatus includes a controller (cell load monitor) which operates to determine when a paging distribution handler should forward a low priority page request to a mobile station in order to decrease a processing (blind) load on a processor and to decrease a load on the air interface resources. The controller utilizes a current paging load (first embodiment) and/or a current traffic load (second embodiment) as a factor to help determine when the low priority page request should be forwarded to the mobile station.Type: GrantFiled: May 17, 2000Date of Patent: May 4, 2004Assignee: Telefonaktiebolaget LM EricssonInventors: Peter Östrup, Sinead McAllister

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: 6292664Abstract: A system and method in a wireless communications environment maximizes voice quality in low capacity situations. A Mobile services Switching Centre (MSC) that is associated with a base station of a cell is capable of assigning speech calls of mobile terminals to either a full-rate (FR) or a half-rate (HR) channel. The FR channels provide better transmitted voice quality but consume twice the bandwidth (two time slots versus only one for HR channels). When occupied cell capacity is low, an MSC assigns connections to FR channels. After occupied cell capacity reaches a predetermined threshold value, the MSC assigns connections to HR channels whenever possible. Also, handover procedures can reclaim available capacity by switching a connection from a FR to a HR channel. The superior voice quality of the FR channels are therefore provided to mobile terminal users more often.Type: GrantFiled: February 6, 1998Date of Patent: September 18, 2001Assignee: Telefon Aktiebolaget LM Ericsson (publ)Inventors: Peter Östrup, Mikael Andersson, Anders Kjell Westroos

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

Patent number: 6125106Abstract: Existing communication connections in a cellular telephone base station can become allocated to communication equipment in a less than optimal fashion. To address this problem a detector identifies when an existing communication connection routed through the base station is terminated. The detector informs a processor which calculates a channel allocation for the remaining communication connections currently routed through the base station which optimizes channel utilization. The optimal channel allocation is then implemented through intra-cell handovers.Type: GrantFiled: August 22, 1997Date of Patent: September 26, 2000Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Peter Ostrup, H.ang.kan Palm, Anders Westroos
