Patent number: 9277460Abstract: User Equipment (UE) receiving non-voice packet switched service in an Evolved Universal Mobile Telecommunications System Terrestial Radio Access Network (eUTRAN) cell undergoes handover to a circuit switched GSM/Edge Radio Access Network (GERAN)/UTRAN cell in response to a requirement for voice service. The voice service is established in the circuit switched domain of a GERAN/UTRAN cell to ensure service continuity regardless of UE mobility that would otherwise not be possible if the voice service was established in the eUTRAN cell. A Gs-like interface between a Mobile Switching Center (MSC) of the CS Core Network and the Mobility Management Entity (MME) of the Evolved Packet Core provides an interface for page requests and location update procedures to be performed.Type: GrantFiled: June 18, 2012Date of Patent: March 1, 2016Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: John Diachina, Hans Krister Mikael Sällberg, Lars Håkan Palm

Patent number: 9137709Abstract: User Equipment (UE) receiving non-voice packet switched services in an Evolved Universal Mobile Telecommunications System Terrestial Radio Access Network (eUTRAN) cell undergoes handover to a circuit switched GSM/Edge Radio Access Network (GERAN)/UTRAN cell in response to a voice service page. An eNodeB of the active eUTRAN cell uses a measurement report history for the UE to select an available circuit switched cell for handover. The voice service is established in the circuit switched domain of a GERAN/UTRAN cell to ensure service continuity regardless of UE mobility that would otherwise not be possible if the voice service was established in the eUTRAN cell.

Patent number: 8553604Abstract: The present invention provides, inter alia, a method of operation of a radio base station in a wireless telecommunications system, in which system information is transmitted on a broadcast control channel. The method comprises the steps of transmitting the broadcast control channel continuously on a first carrier; and also transmitting the broadcast control channel non-continuously and periodically at regular intervals. This prevents or at least minimizes, for example, MBMS data loss when a UE with a single receiver listens to a dedicated MBMS carrier.Type: GrantFiled: September 26, 2007Date of Patent: October 8, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Muhammad Kazmi, Johan Bergman, Lars Håkan Palm, Dirk Gerstenberger, Lars Lindbom

Patent number: 6879832Abstract: In the context of a radio communications system that includes a core network coupled to a radio access network (RAN) and a plurality of mobile terminals, a connection may be established between the core network and one of the plurality of mobile terminals through the radio access network. A temporary RAN identifier is associated with the mobile terminal for the established connection. The temporary RAN identifier is used to assist in the transfer of information pertaining to the established connection or to the establishment of that connection through the radio access network. The radio access network includes a first RAN node associated with a first geographical coverage area and a second RAN node associated with a second geographical coverage area. When the mobile terminal moves from the first coverage area to the second coverage area, the connection is re-established through the RAN by way of the first and second RAN nodes using the temporary RAN identifier.Type: GrantFiled: February 26, 1999Date of Patent: April 12, 2005Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Lars Håkan Palm, Göran Rune, Bo S.

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
