Publication number: 20150289170Abstract: The embodiments herein relate to a method in a target RAN node (105t) for handling selection of a serving operator for a wireless device (101) which has been handed over from a source network to a target shared network (100). The target RAN node (105t) requests an IMSI from a target CN node (110ta) in a same domain that an incoming mobility message is considered for. The target RAN node (105t) receives the requested IMSI. The response further comprises either a used serving operator or an address of a used CN node (110tb). The used serving operator and the used CN node (110tb) are used in another domain than the do main that the incoming mobility message is considered for. The target RAN node (105t) selects the serving operator for the domain that the incoming mobility message is considered for to be the same as indicated for the other domain.Type: ApplicationFiled: November 4, 2013Publication date: October 8, 2015Inventors: Josefin Karlsson, Roland Gustafsson, Peter Ramle, Paul Schliwa-Bertling

Publication number: 20150257052Abstract: The embodiments herein relate to a method in a target RAN node for enabling source based selection of a serving operator which should serve a wireless device in a target shared network. During handover, the target RAN node receives the serving operator that should serve the wireless device in the target shared network. After the handover, the target RAN node transmits a request for the IMSI and receives a response with the IMSI. The target RAN node obtains information about the serving operator stored during the handover. The target RAN node determines a target CN node served by the serving operator if the target shared network is a MOCN network. The target RAN node transmits information indicating the serving operator to the target CN node if the target shared network is a GWCN network.Type: ApplicationFiled: November 4, 2013Publication date: September 10, 2015Inventors: Paul Schliwa-Bertling, Bo Ehrenholm, Roland Gustafsson, Josefin Karlsson

Publication number: 20150078301Abstract: 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: ApplicationFiled: September 18, 2014Publication date: March 19, 2015Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Stefan Karl TOTH, Roland Gustafsson, Gunnar Rydnell

Patent number: 8761805Abstract: A core network node maintains history information configured to provide a log of location information, and uses the history information to determine whether a wireless terminal is in a location update toggling scenario. The history information can also be used to curtail the toggling scenario. One example mode comprises using the history information to determine whether the wireless terminal is toggling between plural radio access networks of differing radio access technologies. Another example mode comprises using the history information to determine whether the wireless terminal is toggling between a first area update location and a second area update location. Yet another example mode comprises using the history information to determine whether the wireless terminal is toggling between a first core network node and a second core network node.Type: GrantFiled: March 24, 2009Date of Patent: June 24, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: György Miklós, Roland Gustafsson, Gunnar Mildh

Patent number: 8428588Abstract: The invention therefore relates to a method, a first Mobility Control Node and a second Mobility Control Node for context handling when a user equipment, UE, moves from a previous Access Network, AN, to a present AN. The ANs are adapted to communicate with a Core Network, CN, and the UE is adapted to communicate wirelessly with the AN's. The method comprises the steps of: the UE detecting that it has entered a Mobility Area, MA, belonging to the present AN, said MA not being registered with the CN, the UE initiating a Mobility Area Update, MAU, procedure in response to the detection by sending a MAU Request message comprising an UE Temporary ID to a Radio Access Node, RAN, the RAN adding a Mobility Area Identity, MAI, to the Request message and forwarding the message to a first Mobility Control Node, MCN, responsible for the present AN, the first MCN deriving one second MCN from the UE Temporary ID and sending a context request message to said second MCN.Type: GrantFiled: December 22, 2008Date of Patent: April 23, 2013Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Roland Gustafsson, Anders Åhlén, Lars-Bertil Olsson, Hans-Olof Sundell, Mikael Wass
