Abstract: The invention relates to a terminal (10) for a cellular communications network (1000). The terminal is configured to maintain a first set (S1) of at least n radio cells, wherein n is equal to or greater than three, wherein a quality measure (q) value of each of the n radio cells, which depends on a received signal power associated with reference signals transmitted in said cells and received by said terminal (10), exceeds a threshold. The terminal further determines whether a quality measure value of a further radio cell, which is not comprised in the first set, exceeds the quality measure value of the radio cell comprised in the first set with the m-th best quality measure value, m ranging from 1 to n−1, by a predetermined amount. If the quality measure value of the further radio cell (c12) exceeds the quality measure value of the m-th best radio cell, modification of the first set is arranged, whereby a second set (S2) is obtained. The second set comprises the further radio cell.

Abstract: A method of wireless data transmission at a first radio access point, including detecting a degradation of a first radio link established for a first frequency band between the first radio access point and a user equipment, and sending, addressed to a network entity, information to trigger a handover or handover decision of the wireless data transmission from the first radio link of the first radio access point operating in the first frequency band to a second radio link of a second radio access point operating in the first frequency band depending on the result of the detection.

Abstract: A computer implemented method of operating a base station of a wireless communication network, wherein the method comprises: comparing a number of missing context release messages (108) with a first criterion; comparing the error rate of connection reestablishment messages (112) with a second criterion; executing a cell global identity search algorithm (110) if at least one of the first and the second criterion is fulfilled, wherein the cell global identity of at least one cell with the physical cell identity of the cell where the criterion was fulfilled is requested via an automatic neighbor relation measurement, and wherein a conflict of physical cell identities is detected and reported to an information algorithm (116) when for the physical cell identity at least two cell global identities are found; an information algorithm for informing a central network element (118) and/or at least one base station (120) of the mobile communication network about a conflict of physical cell identities when a conflict of physical cell identities is reported to the information algorithm; and initiating a reassignment of at least one physical cell identity.
