The cellular communications network (100) comprises a compensating cell (135) for compensating the cell outage and a supporting cell (115) neighboring the compensating cell (135).

Abstract: A set of reporting features are specified for implementation by lower-level Self-Optimizing Network (SON) functions to support the observation of network SON algorithms by high-level SON functions (e.g., OAM functions). The lower-level SON functions may be operative to adjust local parameters related to the network element serving area and/or capacity. The reported SON algorithm events and measurements can be defined such that they can be used by the higher-level SON function to resolve conflicts and control the lower-level SON functions. Some embodiments specify SON function reporting features and their configuration in the framework of the 3GPP defined Itf-N interface specification.

Abstract: The invention relates to a method for service aware scheduling of wireless resources in a wireless network. According to the inventive method, a service request for service delivery of a service type is received (51). A performance to value relationship for the service type is determined (52) and approximated (53) with a scheduling weight function associated with the service type. Previous performance for service delivery related to this service request is evaluated and approximated with a performance estimate (54). A scheduling weight is determined (55) by introducing the performance estimate in the scheduling weight function. Resource scheduling is performed (58) following a step of comparing (56) scheduling weights for on-going service requests. The invention also includes a network node and a system for service aware scheduling of wireless resources in a wireless network.

Abstract: The technology described relates to cell identifiers in which a cell provides two reporting cell identifiers for user equipments (UEs) taking cell measurements. In a non-limiting example embodiment, a secondary synchronization channel (S-SCH) is used to transmit two short cell identities. In this case, a cell uses two sets of signature sequences, one corresponding to the old reporting cell identifier and one corresponding to the new reporting cell identifier.

Abstract: The technology described automatically resolves cell identity collisions/conflicts in a cellular radio communications network. A detecting node determines that a first cell identifier associated with a first conflicting cell is the same as a second cell identifier associated with a second conflicting cell. One of the first and second conflicting cells is selected to change its cell identifier. A different cell identifier is determined for the selected cell. The different cell identifier is then provided to other cells and preferably to user equipment (UE) terminals without disrupting ongoing UE communications.
