摘要： Disclosed is a method for handling of cell identities, performed by a first radio node (520) of a wireless communication network (500), wherein the first radio node (520) provides radio coverage to a first cell (521). The first radio node is connected to at least one second radio node (530, 540, 550, 560, 570), each second radio node providing radio coverage to a second cell (531, 541, 551, 561, 571). Further, the first cell has been assigned a first cell identity, and each of the second cells has been assigned an individual cell identity. The method comprises determining, based on information on the first cell identity and on the cell identities assigned to the second cells (531, 541, 551, 561, 571), that the first cell identity is the same as the cell identity assigned to one of the second cells. The method further comprises triggering change of cell identity for the first cell (521), based on the result of the determining, from the first cell identity to a second cell identity that is not used for any of the second cells, wherein the change of cell identity is triggered at a time point corresponding to a time delay from the determining to the triggering that is dependent on a total number of vacant cell identities for the first cell so that the time delay is shorter the more vacant cell identities there are for the first cell. The method further comprises sending, to the at least one second radio node, information on the change of cell identity from the first cell identity to the second cell identity.

摘要： A method performed by a network node for locating a User Equipment (UE) is provided. The network node, the at least one portable network node and UE operate in a wireless communication network. The network node configures (204) the at least one portable network node to broadcast reference signals. The broadcasted reference signals trigger the UE to subsequently measure and report the quality of the respective reference signals to the network node. The network node then receives (205) subsequent measurement reports from the UE. Each measurement report comprises a current quality value of the reference signals sent by the respective at least one portable network node. The network node manages the respective at least one portable network node to approach the position of the UE by: Meanwhile analyzing the subsequent measurement reports, commanding (206) each of the at least one portable network node to move in a direction that is decided based on the analysis of its corresponding subsequent measurement reports one by one upon receiving them. The moving direction is to be performed such that quality values of its corresponding reference signals in subsequent measurement reports are increasing.

摘要： Disclosed is a method performed by a position calculation node(160) in a wireless communication network (100). The node (160) is arranged for improving accuracy when determining positions in the wireless communication network. The method comprises obtaining a signal transport time value for each of a plurality of different geographical UE positions (UE1, UE2, UE3), wherein the respective signal transport time value relates to the time it takes for a radio signal to travel between a first base station and one of the plurality of UE positions. The method further comprises obtaining a geographical position value for each of the plurality of different geographical UE positions, the position values being independent of the signal transport time values,and determining an actual geographical position for the first base station, based on the obtained signal transport time values, the obtained position values and a predefined geographical position for the first base station.

The method comprises establishing (34) a temporary neighbor cell relation for a received unknown neighbor cell identification; verifying (36) validity of the temporary neighbor cell relation, and establishing (38) a permanent neighbor cell relation based on the established temporary neighbor cell relation, if the temporary neighbor cell relation is found valid, thus avoiding that a false neighbor cell identification results in a faulty permanent neighbor cell relation. Disclosed is also a corresponding apparatus in a network node for establishing neighbor cell relations in a wireless network.

摘要： Disclosed is a method performed by a first network node (131) of a wireless communication network (100), the first network node (131) being of a first radio access network technology. The wireless communication network (100) further comprises a second network node (132) of a second radio access technology. The first network node (131) has a direct signaling connection to a core network (120) whereas the second network node (132) is signaling-connected to the core network (120) via the first network node (131). The method comprises receiving, from a UE (140) that has a primary connection to the first network node (131), a Physical Cell Identity, PCI, that matches a PCI of a cell (152) controlled by the second network node (132), and in response to the reception of the PCI, sending a request to the second network node (132) initiating the second network node to set-up a secondary connection with the UE (140). The method further comprises receiving, from the second network node (132), an acknowledgement of a performed secondary connection set-up with the UE (140), the acknowledgement comprising an ID of the UE (140), or, obtaining information on a secondary connection set-up failure with the UE (140). Disclosed are also corresponding methods for a second and a third network node (132, 133) of the network (100).

摘要： Disclosed is a method for handling allocation of Physical Cell Identities, PCI, in a wireless communication network (100). The method comprises obtaining information on two or more cells (50, 52) that are neighbors or a neighbor´s neighbors, the two or more cells having the same PCI, and information on their current PCI, and obtaining, for each of the two or more cells (50, 52), information on PCIs that the cell can choose from. The method further comprises obtaining information on PCI of cells (56, 58) that are neighbors to any of the two or more cells (50, 52), and obtaining information on a number of cell changes for UEs (140), performed to and/or from each of the two or more cells (50, 52) and a number of cell changes for UEs performed to and/or from each of the cells (56, 58) that are neighbors to any of the two or more cells, over a defined time period. The method further comprises determining which of the two or more cells (50, 52) that should change PCI and to which PCI the determined cell should change, or whether no PCI change is to be performed, based on the information on the current PCI for the two or more cells (50, 52) and the PCIs of the cells (56, 58) that are neighbors to any of the two or more cells as well as on the information on the number of cell changes performed for UEs to and/or from each of the two or more cells (50, 52) and on the information on the number of cell changes performed for UEs to and/or from each of the cells (56, 58) that are neighbors to any of the two or more cells; and changing PCI for the determined cell to the determined PCI, when it is determined to change PCI.
