Abstract: Methods of operating a radio base station of a first cell in a wireless cellular network are disclosed. Each of one or more user equipment devices of the wireless cellular network has an idle mode in which the radio base station is not aware of whether the user equipment device is currently camping on the first cell, and an active mode in which the radio base station is aware of whether the user equipment device is currently camping on the first cell. By setting the radio base station in a disabled state based on various criteria, energy may be saved in the radio base station.

Abstract: Teachings herein include a base station and a relay node for propagating system information changes from the base station to the relay node. Upon receiving changes from the base station, the relay node advantageously determines whether to apply the changes immediately or to defer application until a set time period. The relay node then applies the changes at a time in accordance with that determination. In some embodiments, the relay node employs deferred application for fundamental changes (those changes that would fatally disrupt ongoing communications if applied before the set time period), but employs immediate application for non-fundamental changes in order to minimize relay node complexity. Regardless, the relay node may make the determination based on preconfigured rules, or on control indicators received from the base station. Correspondingly, the base station may generate the control indicators to explicitly direct the relay node to employ immediate application or deferred application.

Abstract: The present invention relates to methods and arrangements of a network node and a UE of a radio access network supporting discontinuous reception, offering a solution that is based on the idea to use more than one sub frame for transmitting paging messages when needed. An indicator in a sub frame with paging messages indicates to the receiving UE if the subsequent sub frame should be read as well.

Abstract: A method for encrypting radio resource control (RRC) messages exchanged between a wireless communication device and a node in a wireless communication system includes separating sequence number rollover events from mobility events while encrypting radio resource control (RRC) messages for exchange within a wireless communication system. According to the method, the sequence number rollover events and mobility events are separated by utilizing a state transition counter, a handover counter, and an overflow counter such that, when the state counter is incremented due to occurrences of a first group of events, the handover counter and the overflow counter are re-set to zero and, when the handover counter is incremented due to occurrences of a second group of events the overflow counter is re-set to zero.

The arrangement comprises a receiver receiving data sequences and a transmitter for transmitting data sequences. Each data sequence has a data size and comprises a sequence number (SN). The arrangement further comprises a processing arrangement configured to add byte numbered sequence numbers to said data sequences passed between layers in a protocol stack for transmission to a transceiver station.

Abstract: A method for power measurements in a cellular communication system comprises receiving measurement configuration orders. Operation of a power meter is controlled in dependence on the measurement configuration orders. Reference signal received powers are measured. A measurement report is compiled and transmitted. The measurement configuration orders comprise cell status information associated with neighboring cells and measurement instructions that are dependent of the cell status of respective cell. The cell status information comprises information about whether the neighboring cell is of a different type than the serving cell. Controlling of the operation of the power meter and/or compiling of the measurement report is performed in dependence on the cell status of the neighboring cell. A method for handover based on such measurement reports is also disclosed as well as Node Bs and user equipments configured to perform such methods.

Abstract: A user equipment, UE, (20) determines a mobility state of a Wi-Fi access point, AP, as one of a moving mobility state and a non-moving mobility state along with control information relating to UE cell (re-)selection and/or handover behavior based on the determined mobility state of the Wi-Fi access point, AP. The UE then controls its cell (re-)selection and/or handover behavior in relation to the Wi-Fi access point, AP based on the determined control information. In a preferred embodiment, the UE can communicate with a cellular base station, BS, and with the Wi-Fi access point, AP. The UE detects the Wi-Fi AP, determines that the Wi-Fi AP is moving based on a moving AP indication, and controls cell (re-Selection and/or handover behavior of the UE based on the determination that the Wi-Fi AP is moving along with other information.

Abstract: A relay node (110) for a radio access network (100), arranged to be a relay node between one or more User Equipments (105) in a cell (125) of the radio access network and a base station (115) serving the cell. The relay node (110) is arranged to identify itself as a relay node in the cell (125) in the radio access network (100), and is also arranged to receive a non-support indication indicating that the base station serving the cell (125) is unable to support a relay node. The relay node (110) is arranged to, upon receiving said non-support indication, attempt to establish itself as a relay node in another cell.

Abstract: A method implemented in an anchor base station configured performing a proxy operation at an anchor base station in which the anchor base station acts as a proxy between a second S-GW or an MME node and a self-backhauled base station. The method includes receiving a data packet destined for the user equipment and mapping the received data packet from an incoming General Packet Radio Service (GPRS) Tunneling Protocol (GTP) tunnel to an outgoing GTP tunnel. The method also includes receiving a control message and modifying elements of the control message while copying other elements in the control message and forwarding the control message between the self-backhauled base station and the second S-GW or MME node.

Abstract: Systems and methods for the configuration of network nodes without a secured connection in a telecommunications system are described herein. These network nodes can be wireless network nodes which are part of the network infrastructure, such as, wireless relays, wireless repeaters and self-back-hauled eNodeBs.

Abstract: Teachings herein include a base station for propagating system information changes from the base station to the relay node. Upon transmitting system information changes to the relay node, the base station defers data transmission between the base station and the relay node until a set time period. In many embodiments, the base station is configured to actually apply the system information changes during this time period, while the relay node applies the changes before then, e.g., by applying them immediately upon reception. The base station's deferral of data transmission until the set time period thus ensures that data transmission does not occur until both the base station and the relay node have applied the pending changes. This in turn prevents radio link failure from occurring due to use of different system parameters by the base station and relay node.

Abstract: A mobility state of a mobile relay node is determined as one of three or more different mobility states. The mobile relay node may determine the mobility state itself or based on received information from another network node. Control information is determined based on the determined mobility state of the mobile relay node and an action is then performed or initiated based on the determined control information. The tree different mobility states may include moving, standing, and at least one additional mobility state. Example additional mobility states of the mobile radio node include: departing, arriving, or temporarily stopped.

Abstract: The technology in this application identifies a relay cell serviced by a relay radio node in a radio access network (RAN) of a cellular communications system in which there is a radio connection between the relay radio node and a donor radio base station. The donor radio base station is identified by a RAN donor radio base station cell identifier. A RAN relay cell identifier is determined that uniquely identifies the relay cell within the RAN, the RAN relay cell identifier including a relay cell identifier and a donor base station identifier. The RAN relay cell identifier is then provided or used as needed so that the relay radio node can transmit the RAN relay cell identifier to uniquely identify the relay cell to one or more radio terminals in the RAN.

Abstract: Embodiments herein relate to a method in a relay node for acquiring information about a type of a radio network connection between a donor radio base station and a radio base station. The relay node and the donor radio base station are comprised in a radio communications network and the donor radio base station is serving the relay node. The relay node receives a message from the donor radio base station, which message is indicating a type of radio network application protocol, which type is related to a type of the radio network connection between the donor radio base station and the radio base station. The relay node determines the type of the radio network connection based on the type of radio network application protocol indicated in the message. The relay node also stores the type of radio network connection in relation to the radio base station for selecting the type of radio network connection when later communicating with the radio base station.

Abstract: A method in a User Equipment (UE) of an Evolved Packet System (EPS) establishes a security key (K_eNB) for protecting Radio Resource Control/User Plane (RRC/UP) traffic exchanged with a serving eNodeB. The method comprises sending a Non-Access Stratum (NAS) Service Request to a Mobility Management Entity (MME), the request indicating a NAS uplink sequence number (NAS_U_SEQ). The method further comprises receiving an indication of the NAS_U_SEQ of the NAS Service Request sent to the MME, back from the MME via the eNodeB. The method further comprises deriving the K_eNB from at least the received indication of the NAS_U_SEQ and from a stored Access Security Management Entity-key (K_ASME) shared with said MME.

Abstract: 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.

Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.

Abstract: A mobile station (MS) and method for base station handover from a source cell of a source base station to a target cell of a target base station in a packet-switched cellular radio network. While the MS is still in the source cell, the MS receives from the network, a handover command message and information regarding a next expected uplink packet for a packet flow subject to lossless packet-switched handover. Upon arrival of the MS in the target cell, the MS transmits an uplink sequence number status message to the target base station providing a downlink sequence number status for the packet flow, and starts uplink data transmission to the target base station beginning with the next expected uplink packet.
