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: 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: The present invention relates to automatic update of a neighbour relation table of a base station. In particular, the present invention relates to a method, a computer program product, and a user terminal for automatically updating a neighbour relation table of a base station, and to a base station and a radio communication system. The base station (2) broadcasts a broadcast message to user terminals (4) served by said base station (2). An instruction for switching user terminals in idle mode to a not idle mode is inserted into the broadcast message. User terminals in idle mode receiving said broadcast message from their serving base station are able to extract said instruction from the broadcast message.
