20130215820 | Relay Nodes - A method, including receiving, at a donor access node from a relay node associated with the donor access node, an identification of one or more other access nodes detected at the relay node and sending configuration information about said relay node from said donor access node to at least one of said one or more other access nodes in advance of an indication that a user equipment associated with the relay node has detected said at least one other access node, without at the same time sending said configuration information to at least one further access node that is detected by one or more other relay nodes or user equipments associated with the donor access node but not detected by said relay node. Wherein said configuration information includes information for setting up a communication with the relay node other than via a core network associated with the donor access node. | 08-22-2013 |
20130229939 | Handover Control for Networks with Several Types of Backhaul Connections - There are provided measures for handover control for backhaul connections, said measures exemplarily including evaluation of the suitability of an access node cell in access network as target for a handover of a terminal based on delay information being indicative of an expected packet delay in a cell of the access node, wherein such delay information may be generated and/or exchanged in the access network. Said measures may exemplarily be applied for improving handover control in relay-enhanced access networks or networks that contain access nodes connected via different kinds of backhaul that can result in different end-to-end packet delays. | 09-05-2013 |
20130303155 | CLASSIFYING FAILURE REPORTS AS EITHER CURRENT OR STALE FOR MOBILITY ROBUSTNESS OPTIMIZATION ADJUSTMENTS - The present disclosure relates to identifying stale failure reports in a cellular communications network. In one embodiment, a node in a cellular communications network receives a failure report associated with a connection failure for a user equipment and determines when the connection failure occurred with respect to a most recent mobility adjustment made by the node. If the connection failure occurred before the most recent mobility adjustment made by the node, the node classifies the failure report as a stale failure report. In one embodiment, if the failure report is classified as a stale failure report, the node discards the failure. In another embodiment, if the failure report is classified as a stale failure report, the node considers the failure report with reduced relevance for a next iteration of a process to determine whether new mobility adjustments are desired. | 11-14-2013 |

20140086138 | Method and Device for Processing Data in a Wireless Network - A method and a device for processing data in a wireless network are provided, wherein a relay node is served by a base station; and wherein the relay node is assigned at least one identification code such that collisions with identification codes of neighboring relay nodes or neighboring base stations are reduced, avoided or solved. Furthermore, a communication system is suggested including at least one such device. | 03-27-2014 |
20140092866 | Node and Method for Enabling a Wireless Terminal to be Served by Multiple Cells in a Communications Network - Example embodiments presented herein are directed towards a wireless terminal and base station, and corresponding methods therein, for providing a handover for a subset of bearers associated with the wireless terminal. The subset of bearers is less than a total number of bearers associated with the wireless terminal. Thus, upon the completion of the handover procedure, at least one bearer will stay connected with a source base station. | 04-03-2014 |
20140148176 | Relay Enhanced Cellular Telecommunication Network - Systems and techniques for avoiding inefficiencies resulting from failed handover attempts. A base station selects one or more mobility management entity (MME) pools for assignment to a relay nod; with the selection being performed so as to minimize or eliminate handover attempts requiring that a target device support a particular MME pool when the MME pool is not supported by the MME. A base station selects, when communicating with a relay node, a subset of the MME pools that it supports and assigns the subset to the base station. UEs served by the relay node are assigned the MME pool or MME pools assigned to the relay node. The relay node is informed of the MME pools supported by one or more neighbor nodes and, when attempting a handover to a neighbor node, attempts an X2 handover only to neighbor nodes supporting an MME pool assigned to the relay node. | 05-29-2014 |
20140192781 | Mobility State Aware Mobile Relay Operation - 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. | 07-10-2014 |

20140302853 | NETWORK NODE, USER EQUIPMENT, METHODS THEREIN, COMPUTER PROGRAMS AND COMPUTER-READABLE STORAGE MEDIUMS TO EXPAND OR SHRINK A COVERAGE AREA OF A CELL - Method performed by a network node of a serving cell. The method is for configuring a user equipment served by the serving cell with a set of values of an offset parameter for triggering handover towards a neighbor cell. The network node and the user equipment operate in a cellular network. The network node configures the user equipment with the set of values of the offset parameter, depending on an uplink-downlink traffic ratio of the user equipment. The user equipment receives from the network node the set of values of the offset parameter for triggering handover towards the neighbor cell. The user equipment uses the received set of values of the offset parameter to expand or shrink the coverage area of the one of the serving cell and the neighbor cell that is the smaller cell, depending on the uplink-downlink traffic ratio distribution of the user equipment. | 10-09-2014 |
