Patent number: 8526958Abstract: A method and system for handover of a mobile station (MS) to an unlicensed mobile access network controller (UNC) in an unlicensed mobile access network (UMAN). In one embodiment, the MS sends an unlicensed mobile access (UMA) radio resource (URR) Registration Request message to the UNC with one or more location identifiers for the MS. The location identifiers may include a GSM Cell Global Identity, an access point (AP) Radio Identity, a set of GPS coordinates, or an AP location. The UNC selects absolute radio frequency channel numbers (ARFCN) and base station identity codes (BSIC) values from a table based on the location identifiers and returns them to the MS in a URR Registration Accept message.Type: GrantFiled: December 8, 2004Date of Patent: September 3, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Hakan Niska, Tomas Nylander, Jari Tapio Vikberg

Patent number: 8320300Abstract: An unlicensed-radio access network is connected to a packet service node in a core network portion of a licensed mobile network. The unlicensed-radio access network includes an access controller connected to the core network portion and having a packet controller, a fixed broadband network connected to the access controller and having a plurality of access points. Each of the access points defines a mini-cell coverage area and supports an unlicensed-radio interface permitting communication of packet data between mobile stations located within a respective mini-cell and the access controller. The access controller comprises a database for storing the identification of mobile stations in association with packet path information addressing said mobile station on the fixed broadband network.Type: GrantFiled: March 9, 2004Date of Patent: November 27, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Tomas Nylander, Jari Tapio Vikberg, Hakan Niska

Patent number: 7733881Abstract: An end node in a packet-switched network is proposed wherein the end node is arranged to exchange packets consisting of a packet header and payload data with a server node connected to the packet-switched network. The end node includes at least one module adapted to extract quality of service parameter values from the headers of packets received over the packet-switched network and to insert the extracted quality of service parameter value in the headers of packets destined for transmission to the server node over the packet-switched network. In this manner the end node automatically adapts the quality of service parameters received over the packet-switched network to correspond with the type of quality of service defined in received packets. Such a system means that only the server node need be configured with the quality of service parameters applicable on the particular packet switched network, so greatly reducing the installation and configuration overheads in a multi-user network.Type: GrantFiled: May 25, 2004Date of Patent: June 8, 2010Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Håkan Niska, Jari Vikberg, Tomas Nylander, Magnus Hallenstal, Lars Peter Öhman

Patent number: 7697934Abstract: The current invention relates to the registration of mobile stations in a mobile communications network. It has particular relevance to handovers and roaming between base stations of an unlicensed radio access network (110) and those of a conventional cellular network (120). As the cells in an unlicensed radio access network have a rather small size, it means that handover potentially can occur far more frequently than for a conventional cellular network. This can result in an undesired ‘ping-pong’ effect, i.e. that the mobile station is switching back and forth between two radio cells too frequently. The current invention reduces this effect by preventing the mobile station to register to the unlicensed radio access network during a modifiable period of time (306).Type: GrantFiled: January 25, 2005Date of Patent: April 13, 2010Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Jari Tapio Vikberg, Tomas Nylander, Håkan Niska

Patent number: 7672272Abstract: A system and method in an unlicensed-radio access network for transporting a circuit-switched payload between an access network controller and a mobile station utilizing a packet-based transmission protocol. The controller sends to the mobile station, a channel activation message that includes a minimum acceptable sample size of the circuit-switched payload to be included in each packet. The mobile station determines whether it can support communications utilizing the minimum acceptable sample size, and if not, selects a larger sample size. The mobile station may send an acknowledgment message that indicates the sample size to be utilized. Alternatively, the mobile station begins transmitting packets, and the controller analyzes received packets to determine the sample size the mobile station is using. The controller then encodes transmissions to the mobile station utilizing the determined sample size.Type: GrantFiled: October 20, 2004Date of Patent: March 2, 2010Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Hakan Niska, Tomas Nylander, Jari Tapio Vikberg

Publication number: 20080227468Abstract: The present invention relates to an improved location process for determining the location of mobile stations when a GSM network is extended by other access networks, for example unlicensed radio access networks. An access network controller supporting a connection with the mobile station sends a location service entity a location request that includes information indicative of at least one positioning method supported by the network element for a particular mobile station. By providing the location service entities with information on the location methods to use, there is no need to configure the location service entities with this information in advance. Moreover, the process is flexible and can be tailored to the network element making the request and thus to the type of connection actually used by the mobile station. There is no need for the location entities to launch several location methods before retrieving sufficiently accurate information since the most suitable methods are communicated in advance.Type: ApplicationFiled: February 25, 2005Publication date: September 18, 2008Applicant: TELEFONAKTIEBOLAGET L.M.

Patent number: 7054629Abstract: The present invention relates to method and means for a system initiated subscriber information redistribution in order to achieve a load redistribution within a pool of core network nodes. The subscribers, that are affected by the redistribution, are determined by the bit values in their TMSI's. These specific TMSI's are then arranged to be treated as invalid by the cellular system. Messages etc. from subscribers with invalid TMSI's will be “trapped” in the cellular system and the subscriber information that belongs to these subscribers will be redistributed to new core network nodes.Type: GrantFiled: August 24, 2001Date of Patent: May 30, 2006Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Klaus Turina, Martin Kaibel, Monica Wifvesson, Åke Arvidsson, Mikael Willgert, Hakan Niska, Kyosti Toivanen

Publication number: 20040052224Abstract: The present invention relates to a method and means for roaming in a cellular radio communication system with a pool of core network nodes, e.g. an MSC-pool (201). A Subscriber Identification Service Node (SISN) is used to handle roaming from a service area supported by a previous MSC/VLR (205) in the MSC-pool to a service area supported by a new MSC/VLR (303) arranged outside of the MSC-pool. The SISN (301) receives an identity request from the new MSC/VLR (303) and forwards it to the previous MSC/VLR (205). The SISN receives a response from the previous MSC/VLR and relays it to the new MSC/VLR. This means that the SISN helps the new MSC/VLR (303) to retrieve data from the right MSC/VLR within the MSC-pool (201).Type: ApplicationFiled: October 2, 2003Publication date: March 18, 2004Inventors: Ake Arvidsson, Mikael Willgert, Keijo Laiho, Hakan Niska, Kyosti Toivanen

Patent number: RE40966Abstract: A method and apparatus for preparing a vendor- and version-independent information model that a cellular telephone base station can use to communicate its capabilities in a plug and play fashion to a network element is disclosed. The information model can also be used to communicate configuration information back to the base station from the network element. The capabilities and configuration information is automatically communicated and utilized, thus reducing the possibility of human operator error in configuring and pre-configuring new or modified base station equipment.Type: GrantFiled: March 11, 2002Date of Patent: November 10, 2009Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Hakan Niska, Bo Kvarnstrom, Jan Oom
