This disclosure relates to a method for effectuating data traffic routing influence for a relocated application service in a core network of a communication system. In an embodiment, the core network may include a communication session control node and an application service node. The method may include transmitting, by the communication session control node, a message to the application service node for notifying a relocation triggering event. The relocation triggering event triggers the application service node to relocate an application service provided to a user equipment in a pre-established communication session from a previous application hosting server to a new application hosting server outside of the mobile core network. The method may further include receiving, by the communication session control node, a relocation information from the application service node such that the communication session control node may reconfigure and modify the data traffic routing for the relocated application service.

A Network Function service provider in a 5GC, for managing SRVCC handover for a UE having a voice session anchored in an IMS in a PS domain in the 5GC is provided. The SRVCC handover moves the voice session to a CS domain in a legacy network. The NF service provider receives an SRVCC handover required message from an NF service consumer, comprising information about a target ID of the legacy network and a target transparent RAN container. The NF service provider obtains, based on the information received in the handover required message, a legacy target transparent RAN container comprising information required for the target RAN node in the legacy radio access network to accept the handover, an identifier related to the voice session, an STN-SR and legacy CS domain security information. The NF service provider initiates handover by transmitting the obtained information to the legacy CN over Sv-interface.

A vehicle remote support system includes a communication system that operates over a plurality of parallel wireless network connections to provide low-latency video from vehicle to a remote support server that provides remote support to the vehicle dependent on real-time video. The vehicle includes a source that encodes multiple versions of the original video segments (e.g., one per wireless network connection) and transmits the multiple versions of the segments to a sink at the remote support server over the respective wireless connections. This redundant multi-path communication system rationally allocates network resources to the managed video streams and balances bandwidth against latency in order to avoid network congestion and safety issues associated with single-path transmissions. In other embodiments, a similar communication system that transmits video or other real-time messages between a source and a sink may be utilized in cloud robotics applications.

A fifth generation (5G) radio access network (RAN) can determine that a user equipment (UE) should fall back to engaging in a communication session over an LTE-based Evolved Packet System (EPS) instead of a 5G system. However, to avoid interrupting setup operations that may be occurring separately for that communication session in an IP Multimedia Subsystem (IMS) apart from the 5G system, the EPS fallback can be delayed such that setup in the IMS can proceed at least to a point at which IMS signaling messages are less likely to be undeliverable due to the EPS fallback.

A system and method is described that allows a communication session to be transferred between endpoints. A user may provide an indication using a first endpoint of the communication session that they desire to transfer the communication session to a second endpoint. Communication session endpoints associated with the user that are available to transfer the communication session can be determined and the user may select one of the available endpoints and then the communication session can be transferred from the first endpoint to the selected endpoint.

A device implementing cellular communication protocol aware multimedia streaming may include at least one processor configured to establish a link for communicating with another device, wherein the link utilizes at least one of a first cellular communication protocol or a second cellular communication protocol. The at least one processor may be configured to determine a bit rate for a video stream to be provided to the other device based at least in part on whether the link utilizes the first cellular communication protocol or the second cellular communication protocol, wherein a first bit rate is determined when the link utilizes the first cellular communication protocol and a second bit rate is determined when the link utilizes the second cellular communication protocol. The at least one processor may be configured to provide, for transmission over the link to the other electronic device, the video stream at the determined bit rate.

There is provided an information processing device, an information processing method, and a program capable of providing seamless streaming. An Edge-DANE on a Source ME-Host makes a synchronous prefetching request to request pre-reading synchronized with the Edge-DANE on the Source ME-Host to an Edge-DANE on a Target ME-Host that streams content to a DASH-Client via a Target RAN when a handover from a Source RAN to the Target RAN occurs due to a movement of the DASH-Client. The present technology can be applied to, for example, an information processing system that provides seamless streaming.

According to various embodiments, an electronic device may include at least one antenna module; and at least one processor configured to receive a communication service from a first communication network, a second communication network, and an IP multimedia subsystem (IMS) network via the at least one antenna module, wherein the at least one processor may be configured to: access the first communication network based on first identification information which corresponds to the first communication network, via the accessed first communication network, based on second identification information which corresponds to the IMS network, request the IMS network to register the electronic device, if registration request to the IMS network fails, access the second communication network, and request the IMS network to register the electronic device via the second communication network. Other various embodiments are possible.

Devices and methods are provided for determining and establishing network path for a streaming video device. The device may receive video from a remote digital video recorder (DVR) through a first access point (AP) wirelessly connected to second AP of the remote DVR, wherein the streaming video device, the first AP, and the remote DVR share a network, wherein the remote DVR includes a third AP. The device may determine a first connection quality associated with a first frequency band between the streaming video device and the first AP. The device may determine a second connection quality associated with a second frequency band between the streaming video device and the second AP. The device may determine that the second connection quality exceeds the first connection quality. The device may establish a direct connection between the streaming video device and the second AP using second frequency band. The device may receive DVR video over the second frequency band.

A method for switching an IMS voice call network includes: identifying a call network which is currently used by a mobile terminal when an IMS voice call is executed by the mobile terminal; switching a VoLTE network which is currently used by the mobile terminal to a VoWiFi network when the call network is the VoLTE network, a use time of the VoLTE network is greater than a timeout time, and a signal intensity of the VoWiFi network reaches a preset first signal threshold value; and switching the VoWiFi network which is currently used by the mobile terminal to the VoLTE network when the call network is the VoWiFi network and a signal intensity of the VoLTE network reaches a preset second signal threshold value. A storage device and a mobile terminal are also provided.
