Abstract: The embodiments herein relate to reducing signaling for DoNAS (Data over Non-Access Stratum) via SGi. In one embodiment, there proposes a method (400) in a mobility management node (203), comprising: establishing (S401) an S11-U connection between the mobility management node (203) and a gateway node (204); monitoring (S402) the frequency of data transferring request for a wireless device (201); and deciding (S404) whether or not to release the S11-U connection based on the frequency of data transferring request. With the embodiments herein, the signaling between the mobility management node and the gateway node can be significantly reduced, without introducing extra signaling or message to the existing network.

Abstract: Methods and apparatuses for instantiation of network service (NS) or virtualized network function (VNF) are disclosed. A virtualized network function manager (VNFM) receives, from a first network management entity, a first request for instantiating or changing a VNF instance. The first request comprises scaling information for at least one scalable VNF deployment unit (VDU) included in the VNF instance. The VNFM instantiates or changes the VNF instance based on the scaling information.
