It is provided a method for adapting a parameter being indicative for a trigger signal for starting measurements, by a first base station of a first radio access network of a first type of radio access technology, of a signal quality of signals being received from a second base station of a second radio access network of a second type of radio access technology. The method includes measuring by a user equipment, which is served by the second base station, the signal quality of signals being received from the first base station, reporting a signal being indicative for the measured signal quality from the user equipment to a network entity, and adapting, by the network entity, a parameter based on the measured signal quality, wherein the parameter is indicative for a trigger signal for starting measuring a further signal quality of signals being received from the second base station.

Method for adapting a parameter being indicative for a trigger signal

A method includes optimizing a handover behavior of a mobile radio communication network including at least a first base station and a second base station. The method includes (a) performing a handover of a UE from the first base station to the second base station; (b) adding an information element representing a property of the UE to a report message including information about the performed handover; (c) forwarding the report message from the second base station to the first base station; and (d) optimizing the handover behavior of the mobile radio communication network based on the added information element. Further, it is described a base station which is configured for carrying out the described handover behavior optimization method.

Optimizing a handover behavior of a mobile radio communication network based on an extended report message comprising information about a performed handover

There is provided a control apparatus for controlling a first cell of a cellular communication network, the control apparatus including a control unit configured for receiving handover related data related to a handover from the first cell to a second cell and a third cell, wherein the control unit is further configured for determining a ranking data for the second cell and the third cell, the ranking data being dependent on the handover related data, and wherein the control unit is further configured for setting at least one operating parameter of the control apparatus depending on the handover related data and the ranking data. Further, the control unit may be configured for determining ranking data for the first cell and a fourth cell, and for determining a value for at least one operating parameter of a control apparatus which controls the second cell.

Self-organized decentralized mobility robustness optimization

A method is proposed by which a mobile device is controlled, which is capable of establishing connection with a first and at least a second type radio access network, the first and the second type radio access network operating with different radio access technologies. In case a radio link failure is detected, when the mobile device was connected with the first type radio access network, it is tried to re-establish connection with the first type radio access network. In case reestablishing the connection with the first type radio access network was not successful, it is tried to re-establish connection with the second type radio access network.

Enhanced connection recovery method for multi-RAT deployments

There are provided measures for a pathloss-based access node wake-up control, more specifically a pathloss-based access node wake-up control in a heterogeneous network environment. Such measures exemplarily include a retrieval of an average handover pathloss level between an access node and a neighboring access node, an estimation of an uplink sounding pathloss level between the access node and a terminal, said terminal being connectable to the access node and the neighboring access node, a comparison of the estimated uplink sounding pathloss level and the retrieved average handover pathloss level, and an enabling of a switch-on of the access node from an inactive state in which a transmitter is switched off to an active state in which the transmitter is switched on, when the estimated uplink sounding pathloss level is smaller than the retrieved average handover.

Pathloss based access node wake-up control

A method and a device for data processing in a wireless network including several base stations are provided, wherein a mobility information is conveyed between at least two base stations. Furthermore, a communication system is suggested including at least one such device.
