  • Methods, core network node and RAN node for enabling emergency services
    Patent number: 10805785
    Abstract: Methods, a core network node (104A) and a node (102A) in a radio access network, RAN, (102), for enabling emergency services for wireless devices in the RAN. The core network node (104A) sends (2:1), to the RAN node (102A), information about one or more Access and Mobility Management Functions, AMFs, that support emergency services, to avoid an emergency fallback procedure for wireless devices in the RAN. The RAN node (102A) then selects (2:2) an AMF (104B) that supports emergency services for a wireless device (100) in the RAN, based on the received information. Thereby, the wireless device will have immediate access to emergency services and no delaying emergency fallback procedure is performed which could be critical in an emergency situation.

    Publication number: 20200305235
    Abstract: Embodiments include methods, performed by a first radio network node (RNN) in a wireless network, to establish a communications interface with a second RNN in the wireless network. Such methods include receiving, from a third RNN in the wireless network, a Transport Network Layer (TNL) address associated with the second RNN. The first and third RNNs are configured for wireless communication with wireless devices via an E-UTRA radio access technology (RAT), and the second RNN is configured for wireless communication via an NR RAT. The third RNN can be a proxy node for discovery of TNL addresses associated with a plurality RNNs configured for wireless communication via the NR RAT. Such methods include establishing the communications interface with the second RNN based on the TNL address received from the third RNN. Other embodiments include complementary methods performed by a second RNN, and RNNs configured to perform such methods.

  • Local switching
    Patent number: 10750574
    Abstract: The invention proposes to introduce a method for a Radio Access Network for providing “Local Switching” between call legs of a call. Within said method the Radio Access Network receives a call identifier for a leg of a call from a Core Network to be handled by the Radio Access Network. The Radio Access Network stores said received call identifier, compares said received call identifier with stored call identifiers for call legs of calls via said Radio Access Network. If said received call identifier matches a stored call identifier the Radio Access Networks establish local switching of call legs identified by the matching call identifier. In an alternative embodiment, the invention proposes to introduce a method for a Core Network for providing local switching for call legs of a call. Within said method the Core Network receives or generates a call identifier for a leg of a call. The Core Network stores said received call identifier and identifies a respective Radio Access Network for said leg of said call.

  • Key management
    Patent number: 10750361
    Abstract: A basestation in a cellular communications network is operable to send a message to a Mobility Management Entity, relating to a suspension or resumption of a connection of a UE, wherein the message contains key renewal information. The Mobility Management Entity receives the message, and determines whether a key renewal condition is met. If the key renewal condition is met, the MME forwards a new NH, NCC pair to the base station. If a message received from the MME includes a NH, NCC pair, the basestation derives keying information using the NH, NCC pair for future use in deriving keys.

  • Methods and nodes for maintaining a wireless connection in a wireless communications network
    Patent number: 10721790
    Abstract: A method and user node for maintaining a connection with a network node when operating in a multi-carrier mode using a first filter configuration to receive multiple frequency carriers simultaneously for downlink communication. The user node applies a mode switching scheme comprising first intervals for the multi-carrier mode and second intervals for a single carrier mode using a second filter configuration to receive a single carrier for the downlink communication. In this case, the user node switches temporarily from the multi-carrier mode to operate in the single carrier mode during the second intervals according to the mode switching scheme. Thereby the user node is enabled to maintain the connection by receiving messages and/or control signalling from the network node over the single frequency carrier during the second intervals, for example when the multi-carrier mode is highly disturbed by interference.
