Methods, systems, and devices for inter-donor topology adaptation in integrated access and backhaul (IAB) networks are described. An example method for wireless communication includes transmitting, by a source donor, a first message comprising an indication that a migrating IAB node is configured to perform an inter-donor switching operation, and receiving a second message comprising feedback information, wherein the source donor is communicatively coupled to the migrating IAB node and a plurality of nodes that are downstream from the migrating IAB node.

The present disclosure relates to session establishment methods, systems, and devices. One example method includes obtaining, by a first mobility management entity, information about a packet data network (PDN) connection that has been established when a terminal accesses an evolved packet core (EPC) network, and obtaining, by the first mobility management entity, single network slice selection assistance information (S-NSSAI) of a network slice corresponding to the PDN connection.

The disclosed technology is directed towards preventing a handover of a Wi-Fi call to a Fifth Generation (5G) standalone cellular network. In one alternative, a 5G standalone usage setting is disabled on a mobile device when Wi-Fi calling is enabled on the mobile device. In another alternative, a 5G standalone usage setting is disabled on a mobile device when Wi-Fi calling is enabled on the mobile device and the mobile device is connected to a Wi-Fi network, which facilitates camping on a 5G standalone network when the mobile device is not connected to a Wi-Fi network. In yet another alternative, a 5G standalone usage setting is disabled on a mobile device when an evolved packet data gateway (ePDG) tunnel is set up on the mobile device, which similarly facilitates camping on a 5G standalone network when the ePDG tunnel is torn down.

An application server switching method, applied to a scenario in which a handover occurs between user plane network elements corresponding to a terminal device, includes obtaining, based on a user plane network element of the user plane network elements after the handover and a correspondence between the user plane network element and an address of a local application server of one or more application servers deployed on a network, the address of the local application server corresponding to the user plane network element after the handover. The correspondence between the user plane network element and the address of the local application server is used to indicate the address of the local application server. The method also includes sending the address of the local application server corresponding to the user plane network element after the handover.

Edge server compute capacity demand in an overlay network is predicted and used to pre-position compute capacity in advance of application-specific demands. Preferably, machine learning is used to proactively predict anticipated compute capacity needs for an edge server region (e.g., a set of co-located edge servers). In advance, compute capacity (application instances) are made available in-region, and data associated with an application instance is migrated to be close to the instance. The approach facilitates compute-at-the-edge services, which require data (state) to be close to a pre-positioned latency-sensitive application instance. Overlay network mapping (globally) may be used for more long-term positioning, with short-duration scheduling then being done in-region as needed. Compute instances and associated state are migrated intelligently based on predicted (e.g., machine-learned) demand, and with full data consistency enforced.

A device obtains a data structure from a computing device, and divides the data structure into data segments. The device obtains a list of user devices from the computing device and obtains, from one or more network devices, a respective location and a respective reachability of each user device. The device determines, based on the respective location of each user device, a set of user devices connected to a base station. The device determines a communication capability of the base station, and determines, based on the communication capability, a subset of the set of user devices and one or more sets of the data segments. The device sends, based on the respective reachability of each user device of the subset of user devices, the one or more sets of data segments to the subset of user devices via the base station.

One disclosure of the present specification provides a communication method related to a change of an application server performed by an SMF node. The method may comprise: a step for transmitting a notification message related to a change of a user plane path to an AF node; a step for receiving a response message from the AF node in response to the notification message; and a step for transmitting a message including information on an IP address of the changed application server to a terminal through an AMF node.

In the present specification, provided is an operation method for an access and mobility management function (AMF). The method comprises a step of receiving a session management (SM) context state notification message from a session management function (SMF). The SM context state notification message can be received on the basis of the failure of a protocol data unit (PDU) session establishment procedure. The PDU session establishment procedure can be triggered for a handover of a PDU session between non-3rd generation partnership project (non-3GPP) access and 3GPP access. The method includes a step of updating an access type related to the PDU session on the basis of the SM context state notification message.

A method of initiating a transfer of an active first-type slave process, executed in a first processing entity of an edge cloud computing layer, to a second processing entity of the edge cloud computing layer, includes, at a first mobile entity, receiving a first heat map relating to the first-type master-slave process, ranking, based on a cost function, possible process sharing connections, between the first mobile entity and one or more second processing entities, for the current location of the first mobile entity and/or a location of the first mobile entity in the near future, determining, based on the ranking, one or more second processing entities as potential target processing entities to transfer the first-type slave process to, and transmitting a processing entity transfer request to a control process executed in the edge cloud computing layer. The request includes an identification of the active first-type slave process and indicates at least one of the second processing entities determined, based on the ranking, as potential target to transfer the active first-type slave process to.
