    • 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.

    • 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.
    • 提供了一种用于使基站(110)能够识别相邻基站(120)的基站(110)中的方法。 正在向用户设备(130)发送(303)请求,命令其向相邻基站(120)发送标识请求消息。 响应于发送的标识请求消息的接收,接收与相邻基站(120)相关联并识别相邻基站(120)的相邻基站标识符(303)。 因此,基站(110)能够识别相邻的基站(120)。 通过接收到相邻的基站标识符,基站能够更直接地了解并且能够与相邻基站进行联系或连接,而不需要通过用户设备来进行。 这可以在稍后的时间点完成,例如为了请求相邻基站对相同或另一个用户设备执行切换测量。

    • In one of its aspects the technology concerns a method of operating a telecommunications system (10) comprising a serving radio base station (50 S ) and a candidate radio base station (50 C ). The serving radio base station (50 S ) comprises a radio base station to which a wireless mobile station (30) provides measurement reports. The serving radio base station (50 S ) and the candidate radio base station (50 C ) are different with respect to at least one of frequency and radio access technology. The method comprises the serving radio base station (50 S ) allowing the mobile station (30) to obtain information broadcasted by the candidate radio base station (50 C ). The information is either information for locating Cell Global Identity (CGI) of the candidate radio base station (50 C ) or the Cell Global Identity (CGI) itself of the radio base station. The mobile station (30) obtains the information from the candidate radio base station (50 C ) during at least one reading gap. The reading gap is a time period in which the mobile station (30) does not receive information from the serving radio base station (50 S ).
