摘要： The present invention relates to an arrangement, a communication network node and method for cell outage compensation in a communication network system comprising a plurality of communication network nodes (15a, 15b) communicating with user equipments (18), where each network node (15a, 15b) is serving at least one cell (19a, 19b), in which the user equipments (18) are situated, via two or more reconfigurable physical antennas (15a1, 15a2, 15b1, 15b2) configured according to an initial antenna parameter set. Cell outage is determined in a network node (15b). One of the reconfigurable physical antennas (15a2) of at least one cell (19a) is made temporarily available for compensation. The available antenna (15a2,) is prepared for compensation by reconfiguring one or more antenna parameters thereof in accordance with a compensating antenna parameter set. A new compensating cell (20) is transmitted from the prepared antenna (15a2). Upon cell recovery the compensating cell (20) is removed and the reconfigurable physical antennas (15a2) of the compensating cell (20) returned to the initial antenna parameter set.

摘要： A method in a base station (110) for enabling the base station (110) to identify a neighbouring base station (120) is provided. A request is being sent (303) to a user equipment (130), commanding it to send an identification requesting message to the neighbouring base station (120). In response to reception of the sent identification requesting message, a neighbouring base station identifier that is associated with and identifies the neighbouring base station (120), is received (303). Thereby the base station (110) is enabled to identify the neighbouring base station (120). By receipt of the neighbouring base station identifier, the base station becomes aware of and is enabled to contact, or connect with, the neighbouring base station more directly, without the need of doing it through the user equipment. This can be done at some later point in time, for example in order to request the neighbouring base station to perform handover measurements with regard to the same or another user equipment.

摘要： The present invention relates to a method and a communication network node for automatically tuning a PRACH configuration parameter in a communication network system comprising radio base stations each serving at least one cell and with which user equipments are communicating on uplink and downlink channels. The PRACH configuration parameter is used for defining the division of uplink resource blocks between PRACH and PUSCH. Load statistics on RACH and PUSCH are collected used for determining a number of RACH opportunities required per time unit. Then a new PRACH configuration parameter having said required number of RACH opportunities per time unit is selected which is replacing the old PRACH configuration parameter.

摘要： In one of its aspects the technology concerns a method of operating a telecommunications system comprising a serving radio base station and a candidate radio base station. The serving radio base station comprises a radio base station to which a wireless mobile station provides measurement reports. The serving radio base station and the candidate radio base station are different with respect to at least one of frequency and radio access technology. The method comprises the serving radio base station allowing the mobile station to obtain information broadcasted by the candidate radio base station. The information is either information for locating Cell Global Identity (CGI) of the candidate radio base station or the Cell Global Identity (CGI) itself of the radio base station. The mobile station obtains the information from the candidate radio base station during at least one reading gap. The reading gap is a time period in which the mobile station does not receive information from the serving radio base station.

摘要： In a cellular radio system a message indicating a change of cell size can be transmitted to a number of affected cells, in particular, neighboring cells. The affected cells receiving such a message can be adapted to use the information in the message when determining self-optimization parameters used for control purposes. Hereby, better response times can be achieved without reducing noise sensitivity.
