A computer device may include a memory configured to store instructions and a processor configured to execute the instructions to determine a service requirement for a client device connected to a WiFi access point in a customer premises network that includes a plurality of WiFi access points. The processor may be further configured to monitor a service requirement parameter, associated with the determined service requirement, for the client device; detect that the service requirement parameter is within a threshold of the determined service requirement; and perform a self-organizing network (SON) action on the customer premises network, in response to detecting that the service requirement parameter is within the threshold of the determined service requirement.

This application provides a call processing method and an apparatus, which are used in an electronic device. The electronic device that is called or initiates a call camps on a first cell of an LTE network after being redirected form a 5G network to the LTE network. The first cell belongs to a tracking area. The method includes: after tracking area update fails, searching, in response to identifying an abnormal signaling flow, for an available cell that does not belong to a tracking area, and initiating the tracking area update in the available cell to attempt to establish a call. Therefore, it is attempted to establish a call in the available cell that does not belong to the tracking area, which can improve a possibility of successfully establishing a call after the redirection from the 5G network to the LTE network.

Aspects of the present disclosure relate to maintaining a network connection while moving from location to location as between different technologies such as from the 2G/3G to the 5G standard, and vice versa. A mobility management entity (MME), e.g., on a 4G platform, controls the transfers of sessions from the 4G platform to the 2G/3G platform when the and/or from the 4G platform to the 5G platform. The MME classifies different sessions on the UE as anchored in GGSN, PGW or SMF. When needed, the MME is then able to transfer the sessions that are transferrable and to terminate the ones that cannot be transferred. By terminating the ones that cannot be transferred, the device can begin reestablishing the connection without waiting, e.g., without waiting for the timeout failure to occur.

[Problem]

This disclosure solves a problem with the service continuity related to inter system change (e.g. EPS and 5GS intersystem change). This disclosure makes it possible to reduce the number of the interactions with the NSACF during the inter system change.

[Solution]

A method of an apparatus related to Session Management Function (SMF) includes sending, to an Access and Mobility Management Function (AMF) apparatus, a first message. The first message includes information indicating that the apparatus interacted with a Network Slice Admission Control Function (NSACF) apparatus for Network Slice Admission Control (NSAC). The method includes retaining a second message for the NSAC to be sent to the NSACF in a case where the first message includes the information.

A recovery method for data traffic interruption, and a terminal and a storage medium are disclosed. The method may include: detecting data traffic interruption in a Protocol Data Unit (PDU) session; determining whether the PDU session currently meets a session switching condition; and in response to a determination that the PDU session currently meets the session switching condition, switching the PDU session.

The present specification relates to a method by which a first terminal performs a session handover in a wireless communication system, wherein the method for performing a session handover can comprise the steps of: forming an ASP session with a second terminal by a first connecting method; transmitting a session handover request to the second terminal; receiving a session handover response from the second terminal; and transmitting a session handover confirm to the second terminal, wherein, when the session handover response is received from the second terminal, the formed ASP session can be handed over by a second connecting method.

The application relates to a method for operating a first radio access node 100 of a first packet switched mobile communications network. The first radio access node receives a request for establishing a data packet session requiring a defined quality of service and determines that the data packet session cannot be handled by the first packet switched communications network. The first radio access node triggers a hand over to a second packet switched mobile communications network based on the determining and transmits an indication towards a mobile entity (200) involved in the data packet session indicating that a resource for the data packet session will be available when the handover is completed.

Switching the providing of a conversation among communication links is described. An electronic device can determine that a mobile device is being used to provide a conversation (e.g., a phone call) using a first communication link. The mobile device can enter an environment that includes a second communication link. The conversation can be switched to the second communication link that provides more content than the first communication link (e.g., audio and visual content rather than just audio content).

Embodiments for performing a fast return to Wi-Fi following completion of a cellular voice call are provided. These embodiments include detecting that a device has switched from communicating over a Wi-Fi interface to communicating over a cellular interface; determining the earliest time that the device can switch back to Wi-Fi; and instituting the switch. In some embodiments, the process of performing a fast return to Wi-Fi is carried out by devices having small form factors, such as smartwatches and other wearables, which may be susceptible to coexistence and peak power problems. The fast return to Wi-Fi embodiments disclosed herein allow a device to perform a voice call over a cellular interface when Wi-Fi calling is not available, and switch over to a Wi-Fi interface immediately upon completion of the voice call in order to conserve battery life, achieve higher data speeds, and avoid high costs associated with cellular data transmissions.

A method performed by user equipment (UE) includes receiving a request to access a service unavailable through a first network cell associated with the UE, and receiving a message from an access device associated with the first network cell, wherein the message identifies a plurality of second network cells providing the service.
