摘要： A method performed by a first peer node for acting as a P2P proxy for a user device is provided. The first peer node operates in a communications network. The first peer node establishes (201) a renewable energy profile of the first peer node used for powering the first peer node. The renewable energy profile indicates to what extent one or more energy sources are renewable. When a proportion of renewable energy according to the established renewable energy profile exceeds a first threshold, the first peer node acts (205) as a P2P proxy for the user device for downloading a piece of data to the user device by being powered according to its renewable energy profile.

摘要： The embodiments herein relate to a method performed by a UE (103) for handling SI. The UE obtains one or multiple public keys for SI signature verification. Each of the one or multiple public keys is associated with a validity area of an access network where the public key is valid. The UE obtains a SI together with a SI signature from a network node (101) covering a cell. The SI comprises area identification information. The UE determines (103), based on the area identification information comprised in the SI, the validity area that the cell belongs to and the corresponding public key. The UE (103) verifies the SI signature using the determined corresponding public key.

摘要： A network node (26, 400) is configured for use in a wireless communication network (10). The network node (26, 400) receives a request to establish a session (14-1) for a device (12-1) in a group (18), e.g., a 5G Local Area Network group (18). The network node (26, 400) determines a user plane security policy (24-1) for the session (!4-1), based on a user plane security policy (28) for the group (18). The user plane security policy (28) for the group (18) may specify a policy for securing a user plane path of a session for any device in the group (18). The network node (26, 400) may then transmit, to an access node of the wireless communication network (10), control signaling indicating the determined user plane security policy (24-1).

摘要： Methods, a wireless device (110), a radio network node (120) and a core network node (130) for reservation of bandwidth are disclosed. The wireless device (110) sends (A010), to the core network node (130), an inquiry for reservation of bandwidth. The inquiry comprises information about a route to be travelled by the wireless device (110), a start time, and an indication about the bandwidth to be reserved. The core network node (130) sends (A040), to the radio network node (120), a command for reservation of the bandwidth to be reserved for the wireless device (110). The command comprises the indication, information relating to one or more cells of the radio network node (120), in which one or more cells bandwidth is to be reserved according to the indication, a parameter indicating a period of time during which the wireless device (110) is expected to make use of at least some of the bandwidth to be reserved, and an identity of the wireless device (110). The radio network node (120) determines (A060) grant or denial of the command based on the period of time and based on available bandwidth of the radio network node (120). Corresponding computer programs and computer program carriers are also disclosed.
