摘要:
A method in a first radio access node for preparing handover of a user equipment in a wireless communications network. The user equipment is to be handed over from being served by the first radio access node to being served by a second radio access node. The first radio access node is connected to a first core network node currently serving the user equipment. Based on whether or not the second radio access node is connected to the first core network node the first radio access node selects (504) an interface for signalling handover of the user equipment among: a first interface interfacing the first radio access node and the first core network node, and a second interface. The second interface is an interface between the first radio access node and the second radio access node.
摘要:
Embodiments herein relate to a method performed by a distributed unit of a network node, for establishing a connection between the distributed unit and a central unit connected to a core part of the wireless network. The network node includes the central unit and at least the distributed unit. The distributed unit performs a Domain Name Server lookup for a proxy central unit, which will act as a temporary or initial central unit with regard to a configuration transfer procedure. The distributed unit further receives an ip address of the proxy central unit and initiates the configuration transfer procedure by sending a configuration transfer message to the ip address of the proxy central unit. The distributed unit further receives an ip address of the central unit and establishes a connection between the distributed unit and the central unit using the received ip address of the central unit.
摘要:
A method in a network node for sending a message to a first group of wireless devices. The first group of wireless devices is served by a Primary Cell. The network node and the first group of wireless devices operate in a wireless communications network. The network node sends a single message to the first group of wireless devices. The wireless devices in the first group of wireless devices are in carrier aggregation mode, being further served by a Secondary Cell, SCell, of the network node. The single message comprises a first common Radio Network Temporary Identifier addressing all the wireless devices in the first group of wireless devices. The single message further comprises information related to the SCell.
