摘要： A network node (300a) receives, over an interface between the network node (300a) and a further network node (300b), a message comprising paired user equipment (UE) identifiers for UE identification over the interface to the network node (300a) and further network node (300b), respectively. Responsive to determining that the identifier for UE identification to the network node (300a) uniquely identifies a UE (150) to the network node (300a), the network node (300a) validates the message irrespective of whether the identifier for UE identification to the further network node (300b) uniquely identifies the UE (150) to the further network node (300b).

摘要： A network node (700) of a radio access network (RAN) of a wireless communication network (10) provides user plane security by establishing a secure tunnel between first and second tunnel endpoints (160, 180, 370, 195, 220, 230) that will handle respective protocol layers of a same protocol stack for a Data Radio Bearer (DRB) (330, 340, 350, 360) that is dedicated to user plane traffic and has yet to be established. Establishing the secure tunnel comprises exchanging an inner Internet Protocol (IP) address and an outer IP address of each of the endpoints (160, 180, 370, 195, 220, 230) between the endpoints (160, 180, 370, 195, 220, 230).

摘要： A method performed by a first network node (101) for enabling a second feeder link (132) to be established between a second network node (102) and an airborne or orbital communication node (110) in non-terrestrial communications network (100) to handle wireless devices (121) being served by the airborne or orbital communication node (110) is provided. The first network node (101) is handling the wireless devices (121) served by the airborne or orbital communication node (110) over a first feeder link (131) between the first network node (101) and the airborne or orbital communication node (110). The method comprises determining (701) that the wireless devices served by the airborne or orbital communication node (110) are to be handled by the second network node (102) over the second feeder link (132). Also, the method comprises initiating (702) the second feeder link (132) to be established between the second network node (102) and the airborne or orbital communication node (110). Further, a first network node (101) for enabling a second feeder link (132) to be established between a second network node (102) and an airborne or orbital communication node (110) in non-terrestrial communications network (100) to handle wireless devices (121) being served by the airborne or orbital communication node (110) is also provided. A second network node and a method therein, as well as, computer programs and carriers are further provided.

摘要： A system and method to perform fast transition time interval switching in an uplink multicarrier system. In one embodiment, an apparatus, and related method, is configured to receive a first user equipment power headroom (“UPH”) filtering value for a first uplink carrier from a user equipment, identify a measurement identifier with a first value for the first uplink carrier, and transmit the first UPH filtering value and the measurement identifier with the first value to a radio network controller.

摘要： Embodiments herein relate to a method, performed by a Radio Network Controller, (RNC) for setting up a secondary uplink carrier. The RNC sends a dedicated radio link message to a network node. The dedicated radio link message comprises a first Information Element (IE) which indicates a Transmission Time Interval (TTI) value out of a plurality of TTI values available for the radio link. Embodiments herein further relate to a method, performed by a network node, for setting up a secondary uplink carrier. The network node receives the dedicated radio link message from the RNC. The dedicated radio link message comprises the first IE, which indicates a TTI value out of a plurality of TTI values available for the secondary uplink carrier that is to be set up.

摘要： A radio network node receives a page request from a core network node. The page request indicates to page a wireless communication device. The radio network node determines a next occurrence of a monitoring window during which the wireless communication device will monitor a paging channel associated with the radio network node. If the amount of time until the next occurrence of the monitoring window exceeds an amount of time that the radio network node can store the page request, the radio network node discards the page request and sends a response to the core network node indicating that the page request was discarded; the response includes a paging timer value that indicates when the core network node should repeat the page request.

摘要： A method performed by a server for assisting a radio network node to handle a set of positioning assistance data for positioning one or more User Equipments, UEs, in a wireless communications network is provided.
Based on importance, the server determines a priority associated to the respective positioning assistance data out of the set of positioning assistance data.
The server assists the radio network node by sending the set of positioning assistance data, and information about the determined priority associated to the respective positioning assistance data. The determined priority enables the radio network node to determine a schedule for broadcast of at least some of the respective positioning assistance data out of the set of positioning assistance data, in respect to available resources in the radio network node.-
