    Abstract: An uplink signal-to-interference ratio for each of multiple mobile radio terminal connections supported in a cell in a cellular communications system is estimated. A signal-to-interference ratio error is determined for selected ones of the estimated uplink signal-to-interference ratios. One or more signal-to-interference ratio errors are identified that exceed a signal-to-interference ratio error threshold. An instability indicator associated with the cell is determined based on the one or more identified signal-to-interference ratio errors. A load control decision and/or a decision for scheduling one or more uplink mobile radio transmissions in the cell may then be made based on the instability indicator, e.g., to prevent a transmission power rush in the uplink in the cell and/or to efficiently use available resources for uplink transmissions.

    Abstract: A first base station provides radio communication service to user equipments, UEs, and a second base station that provides radio communication service to UEs in adjacent cell service area. The first base station receives cell range expansion, CRE, information from the second base station for expanding the size of the first cell and evaluates handover of one or more UEs with respect to the second cell based on the CRE information. In one embodiment, the second base station determines a CRE related configuration that includes the CRE information with respect to the first cell, sends the CRE information to the first base station. For example, the second base station may send a handover request including the CRE information to the first base station. The second base station also may consider CRE information in handover evaluation.

    Abstract: The invention relates to method and arrangement for automated optimization of network element settings in a wireless network. For a first optimization state, a first forward triggering condition and a first range of network element settings, allowable in first network element settings optimization are determined. For a further automated optimization state, determining a further forward triggering condition, and a further range of network element settings, allowable in a further network element setting optimization. An initial set of network element settings is assigned to an initial automated optimization state. The first forward triggering condition is evaluated and a migration to the first automated optimization state is performed upon fulfillment of the first forward triggering condition. A further forward triggering condition is evaluated and a migration to a further automated optimization state is performed upon the further forward triggering condition. The migrating is repeated until reaching a final automated optimization state.
