Patent number: 12075505Abstract: A method and network node for backhaul link failure recovery are disclosed. A network node is configured to attempt to find an alternative backhaul link to replace the failed backhaul link. If the attempt to find an alternative backhaul link fails, then the network node communicates a first indication of an existence of the failure to the first child network node one level below the network node affected by the failure and causes the first child network node to find another network node to serve as a new parent network node. If the first child network node finds another node to serve as the new parent network node then the network node is configured to serve as a second child network node of the first child network node so that the first child network node serves as a parent of the network node.Type: GrantFiled: February 12, 2020Date of Patent: August 27, 2024Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Ajmal Muhammad, Oumer Teyeb, Gunnar Mildh

Patent number: 12022338Abstract: A wireless device suspends a connection with a first access network and enters an inactive state. While the connection with the first access network is suspended and the wireless device is in the inactive state, the wireless device camps in a specific area of a second wireless communication network that is included in a notification area within which the wireless device is allowed to move without notifying either the second wireless communication network or a first wireless communication network that includes the first access network. Upon camping in the specific area, the wireless device starts a timer. Responsive to expiry of the timer, the wireless device switches from the inactive state to an idle state and/or transmits to the second access network signaling indicating that the wireless device is in the specific area or that the wireless device requests a connection to the second access network.Type: GrantFiled: February 27, 2020Date of Patent: June 25, 2024Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Patrik Rugeland, Icaro L.
