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： An object of the present invention is to provide a mechanism for observing random access performance in a Long Term Evolution network. The object is achieved by a method in a base station (110). The method observes a random access performance in a Long Term Evolution communication network. The random access performance is defined by an access delay, where the access delay is a delay from the initial random access attempt until access is granted. The method comprises receiving a respective report from a plural of user equipments (115), where each of the respective user equipment (115) has performed a random access process and has received a random access grant. Respective report will comprise access delay related random access information. Further the method comprises determining a respective access delay, which is based on each of the access delay related random access information. The determined access delays will be the basis for the estimation of access delay statistics. Finally will the random access performance be observed based on the access delay statistics.

摘要： In a method and an apparatus for determining when a cell of a cellular radio system can enter a discontinuous transmission mode is provided. By evaluating qualities from both the cell and neighboring cells for a number of positions and calculating a statistically expected quality distribution of the evaluated qualities conditioned on that certain cells are in discontinuous transmission mode it is possible to generate a distribution which can be compared with at least one requirement thresholds. Based on the comparison it is possible to determine if first cell can use discontinuous transmission mode and still fulfill the requirements.

摘要： The present invention relates to a method and a communication network node for enabling automatic planning and handling of root sequences used at random access in a communication network system, wherein user equipments (18) are accessing a cell (19a) being served by said communication network node. Root sequence usage information from neighbouring cells (19b, 19c) is acquired. Root sequence conflicts between root sequences used in said served cell (19a) and root sequences used in said neighbouring cells (19b, 19c) are detected. When no conflict is detected, appropriate new root sequence(s) is/are selected. Otherwise, detected root sequence conflicts are resolved by deriving a new set of root sequences.

摘要： A method in a base station (110) for enabling the base station (110) to identify a neighboring 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 neighboring base station (120). In response to reception of the sent identification requesting message, a neighboring base station identifier that is associated with and identifies the neighboring base station (120), is received (303). Thereby the base station (110) is enabled to identify the neighboring base station (120). By receipt of the neighboring base station identifier, the base station becomes aware of and is enabled to contact, or connect with, the neighboring 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 neighboring base station to perform handover measurements with regard to the same or another user equipment.
