Patent number: 10555224Abstract: Example embodiments presented herein are directed towards a stateless mobility management node, and corresponding methods therein, for handling a mobility procedure for a wireless device within a wireless communications network. The example embodiments provide for the management of a common external database shared by the stateless mobility management node and at least one other stateless mobility management node, and storing context information for wireless devices served by the stateless mobility management nodes. Such management allows for migrating the network towards a virtualized and stateless architecture. Thus, stateless mobility management nodes with an external database may interoperate with legacy stateful mobility management nodes.Type: GrantFiled: August 14, 2015Date of Patent: February 4, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Gunnar Rydnell, Stefan Karl Toth

Patent number: 10368220Abstract: A server for controlling user MTC devices. The server ascertains if a user MTC device has an IP connection to a cellular access network, and if so, sends a message to trigger the user MTC device to initiate an application defined in the message. If a user MTC device does not have an IP connection, the server ascertains if the user MTC device is a mobile or a stationary user MTC device, and for a stationary user MTC device, the server sends a message to the cellular access network to trigger the user MTC device to initiate an IP connection, and for a mobile user MTC device, waits until the user MTC device has an IP connection, and for both kinds of user MTC devices, when the user MTC device has an IP connection, transmits a message to the user MTC device to initiate an application defined in the message.Type: GrantFiled: January 23, 2012Date of Patent: July 30, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Stefan Karl Toth, Gunnar Rydnell, Hans Bertil Rönneke, Hans-Åke Lund

Patent number: 10362451Abstract: A method, device, and computer program product for facilitating device-to-device, D2D, communication among wireless communication devices, WCDs, is provided. The device is a first WCD that receives a wireless packet broadcasted by a second WCD. The wireless packet has one or more of i) a group identifier that identifies a group to which the second WCD belongs and ii) an application identifier that identifies an application which generated at least part of the wireless packet. The first WCD extracts from the wireless packet one or more of the group identifier and the application identifier. The first WCD determines whether to discard the wireless packet based on the one or more of the group identifier and the application identifier extracted from the wireless packet.Type: GrantFiled: February 24, 2017Date of Patent: July 23, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Stefan Karl Toth, Roland Gustafsson, Gunnar Rydnell

Patent number: 10349301Abstract: A method performed by a first network node operating in a wireless communication network for enabling events triggered by a wireless device served by the first network node to be reported in the wireless communications network is provided. The first network node determines that an event has been triggered by the wireless device. Then, the first network node context information associated with the wireless device from a database node that is shared externally by the first network node with one or more network nodes in the wireless communications network, which context information indicates that events triggered in the first network node by the wireless device is to be reported in the wireless communications network. After the obtaining, the first network node determines that events triggered by the wireless device is to be reported in the wireless communications network based on the obtained context information.Type: GrantFiled: September 18, 2015Date of Patent: July 9, 2019Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Stefan Karl Toth, Lars Lövsén, Gunnar Rydnell

Patent number: 9730177Abstract: A quite simple and effective way for simplifying the mobile system for the mobile broadband customers, thereby lowering the equipment costs and in the end allowing for more competitive flat rate fees, is to direct the traffic from mobile broadband devices (110) to dedicated gateways (120). The mobile broadband device (110) is comprised in a user equipment (105) in a wireless communication network (100). The wireless communication network (100) comprises a network node (115) is arranged to be connected to the mobile broadband device (110). First, the mobile broadband device (110) sends (200, 300) an attach request message to the network node (115). The attach request comprises an information element indicating that the device (110) is a broadband device. Then, the device (110) receives (301) an attach accept message from the network node (115) comprising address information of the dedicated gateway (120).Type: GrantFiled: February 12, 2016Date of Patent: August 8, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Hans Rönneke, Gunnar Rydnell, Stefan Karl Toth
