Patent number: 9775073Abstract: In one aspect, the invention provides an improved procedure for handing over a connection from a source network node to a target network node. In some embodiments, this procedure includes the following steps: (a) receiving, at a gateway, a handover required message transmitted from the source network node; (b) generating, at the gateway, a handover request message in response to receiving the handover required message; and (c) transmitting, from the gateway, the handover request message to the target network node. In another aspect, the invention provides an improved gateway that is configured to intercept and handle handover signaling.Type: GrantFiled: May 25, 2009Date of Patent: September 26, 2017Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Jari Vikberg, Thomas Lindqvist, Tomas Nylander

Patent number: 9661537Abstract: Method and arrangement in a network control node, for performing access control of a mobile node in a handover from a source cell to a target subscriber group cell. The method comprises obtaining a network based allowed subscriber group list, receiving a target subscriber group identification, checking if the target subscriber group identification is comprised in the obtained network based allowed subscriber group list. If it is, information from a target network control node is obtained, verifying that the received subscriber group identification corresponds to the target subscriber group cell. Still further, the method comprises granting the mobile node access to the target subscriber group cell. Also, a method and arrangement in a target network control node, for assisting a network control node in performing access control for a mobile node in a handover from a source cell to a target subscriber group cell is provided.Type: GrantFiled: January 29, 2016Date of Patent: May 23, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Ann-Christine Sander, Thomas Lindqvist, Arne Norefors, Tomas Nylander, Johan Rune, Jari Vikberg

Publication number: 20070254620Abstract: A radio access network (24) comprises a radio network control node (26); a database (40); and a femto radio base station node (28f) serving a femtocell (Cf) of the radio access network. The femto radio base station node (28f) comprises a receiver (54) for receiving scanned cell information broadcast for one or more receivable cells of the radio access network, and a reporting unit (60). The reporting unit (60) provides the scanned cell information for the one or more receivable cells of the radio access network to the radio network control node (26). The radio network control node (60) is arranged, upon receipt of the scanned cell information, for providing configuration information to the femto radio base station node (for configuring the femto radio base station node) and for storing macro cell information for one or more receivable cells in the database (40). The macrocell information is stored in the database (40) in association with the femto radio base station node.Type: ApplicationFiled: April 28, 2006Publication date: November 1, 2007Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventors: Thomas Lindqvist, Tomas Nylander, Jari Vikberg
