Method and apparatus for application server change are disclosed. A method comprises obtaining information on application server change for an application when server changes to a target application server; and making decision to inform UE to rediscover the target application server for the application or configure UPF to steer traffic to and from the target application server for the application

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit a resource status request requesting load information related to load balancing between the wireless communication device and one or more other wireless communication devices. The wireless communication device may receive a resource status response including the load information in response to the request. In other aspects, a User Equipment (UE) may receive a Radio Resource Control (RRC) configuration including a set of target cells for a conditional handover procedure and load information of the target cells. The UE may select a target cell from the set of target cells for the conditional handover procedure based at least on the load information of the target cells. Numerous other aspects are provided.

Embodiments of this application provide a communication path switching method, an apparatus, and a system. The method includes: A first terminal receives a first radio resource control (RRC) connection reconfiguration message sent by a first network device, the first RRC connection reconfiguration message comprises a first identifier, a second identifier, and first indication information, the first identifier identifies the first terminal, the first indication information indicates the first terminal to perform communication path switching, the second identifier identifies a second terminal, and the second terminal is a target terminal for the communication path switching; and the first terminal sends a first message to the second terminal, the first message comprises the first identifier.

A method, system and apparatus are disclosed for preventing reestablishment at descendant nodes with no alternative paths in Integrated Access Backhaul (IAB) networks. In one embodiment, a method implemented in a network node configured to communicate with at least one descendant node over a backhaul network includes transmitting an indication to the at least one descendant network node in which the indication is associated with a radio link failure; and receiving at least one message in response to the indication, the at least one message being associated with an alternative path availability of the at least one descendant network node toward a third network node.

A method and device are disclosed from the perspective of a relay UE for Radio Resource Control (RRC) connection establishment to support User Equipment (UE)-to-Network relaying. In one embodiment, the method includes a relay UE establishing a PC5 RRC connection or a PC5 unicast link with a remote UE. The method also includes the relay UE receiving a RRC message from the remote UE. Furthermore, the method includes the relay UE initiating a RRC connection establishment with a network node in response to reception of the RRC message. In addition, the method includes the relay UE transmitting a Disconnect Request message to the remote UE to release the PC5 RRC connection or the PC5 unicast link or transmits a PC5 RRC message to the remote UE to inform the remote UE of a failure of the RRC connection establishment, if the RRC connection establishment fails.

A method performed by a first sensor device registered with a processing node via a network comprises steps of: i. detecting a trigger event, ii. broadcasting a signal to a second sensor device and establishing a direct connection between the first sensor device and the second sensor device, iii. transferring identity information and connection information to the second sensor device via the direct connection, the former identifying the first sensor device to the processing node, the latter being used by the first sensor device to connect to the processing node, and iv. receiving confirmation that the second sensor device has been registered with the processing node as a replacement for the first sensor device and removing the connection information from the first sensor device.

Technology related to processing network packets in a subscriber-aware manner is disclosed. In one example, a method includes selecting one or more subscribers to move from a first network processing node to a second network processing node. In response to the selection, subscriber data associated with the one or more subscribers can be programmed at the second network processing node. After the subscriber data associated with the one or more subscribers is programmed on the second network processing node, a software defined network (SDN) switch can be reprogrammed to forward network traffic having network addresses associated with the one or more subscribers to the second network processing node instead of the first network processing node.

A method including transmitting, by a first device in communication with a second device in a mesh network, periodic requests to an infrastructure device associated with the mesh network, the periodic requests requesting the infrastructure device to determine a current communication parameter associated with the first device; monitoring, by the first device during an interval between transmission of the periodic requests, occurrence of a triggering event; and transmitting, by the first device based at least in part on determining occurrence of the triggering event during the interval, an aperiodic request the infrastructure device to determine the current communication parameter associated with the first device. Various other aspects are contemplated.
