  • Reducing signaling for data over non-access stratum via an SGI interface
    Patent number: 11528779
    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.
