    摘要: 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 node, 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.

    摘要: User equipments UEs send their buffer status reports and data to a relay node RN. The RN stores the data in actual buffers per radio bearer group RBG, and stores the UEs buffer occupancies in virtual buffers per RBG. The RN then sends its own status report to the controlling eNBr with the actual buffer occupancy and information about the virtual buffer occupancy. This enables the eNBr to know in advance the volume of data incoming to the RN's actual buffers, as well as the current occupancy of those buffers, so as to better allocate radio resources. Further, the RN can take soundings of the uplink channels between UEs and the RN, which are then aggregated across the RBRs and sent to the eNBr as a special UL CQI report. The eNBr is thereby enabled to anticipate how soon the data in the UE buffers will appear in the RN's actual buffers (from the additional information of average UL CQI info and virtual buffer status), and thus better allocate the RBRs to be used for the different RBGs in the RN-eNB link as well as the optimal set of RBRs to the UE-RN link, which the RN can redistribute among the UEs that it is serving.

    摘要: Some embodiments provide a mobile relay node, RN, (16) with complete and valid neighbor cell information. The RN (16) requests this information from a donor base station (12) upon detecting a defined condition characteristically indicating that movement of the RN (16) has rendered previously obtained neighbor cell information incomplete or invalid. The RN (16) may generate the request to identify cells (18) currently neighboring the mobile cell (20). The donor base station (12) may then provide the RN (16) information that more specifically pertains to the mobile cell's neighbors, rather than generally pertaining to the donor cell's neighbors. Other embodiments compensate for the RN's incomplete or invalid neighbor cell information. These embodiments permit the RN (16) to identify a target cell (18) with a non-unique cell identifier in a handover message sent to the donor base station (12). The donor base station (12) resolves this non-unique identifier and replaces it with the corresponding unique identifier for sending the message towards the target cell (18).

    摘要: Embodiments herein relate to a method in a second network node (13,14) for detecting a short stay handover of a user equipment (11) in a second cell (16) in a telecommunication system (10). The user equipment (11) is handed over from a first cell (15) to the second cell (16) and from the second cell (16) to a third cell (17) in the telecommunication system (10). The second network node sends, to a first network node (12,18), an indication in a message that a short stay handover has occurred when determined that the user equipment (11) is handed over to the third cell (17) before a time threshold, thereby enabling the first network node (12,18) to detect the short stay handover.

    摘要: 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.

    摘要: 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.

    摘要: A telecommunications node (28) comprises a communication interface (36) and a parameter controller (40). The node (28) acquires timing advance (TA) information and angle of arrival (AoA) information through the communication interface (36). The timing advance (TA) information and angle of arrival (AoA) information are based on uplink signals received over a radio interface (32) from one or more wireless terminals (30) that are involved or have been involved in handover. The parameter controller (40) uses the timing advance (TA) information and the angle of arrival (AoA) information to make a determination of size and shape of a cell of a radio access network.
