Systems and methods are described for simultaneously accessing a plurality of services on Wi-Fi. The method comprises registering a first and second Media Access Control (MAC) identification (ID) with a first and second IP Multimedia System (IMS), by use of a User Equipment (UE). The UE comprises a first MAC ID associated with a first Subscriber Identification Module (SIM) card and a second MAC ID associated with a second SIM card. Use of a first service through a first Access Point (AP) without interrupting a second service may be available with registration of a first and second MAC ID.

Method and a user equipment (UE) for accessing plurality of services on Wi-Fi simultaneously

A method performed by a User Equipment (UE) for managing sub-flow communications is provided, the method includes selecting a sub-flow among a plurality of sub-flows of the UE based on a set of parameters associated with each of the plurality of sub-flows, and transmitting a plurality of Transmission Control Protocol (TCP) acknowledgement messages in a single frame through the selected sub-flow, the plurality of TCP acknowledgement messages being associated with the plurality of sub-flows.

Managing sub-flow communications in user equipment

A method for establishing a virtual reality (VR) call between a caller VR device and a callee VR device, the method includes determining which of the caller VR device or the callee VR device should perform a stitching operation associated with the VR call based on a first plurality of parameters associated with the callee VR device and a second plurality of parameters associated with the caller VR device, and causing transmission of one of a plurality of media contents or a stitched media content from the caller VR device to the callee VR device after establishment of the VR call based on the determining.

Apparatuses and methods for establishing virtual reality (VR) call between caller VR device and callee VR device

An electronic device process data including a compressed header is provided. The electronic device includes a controller configured to generate a data packet comprising a header compressed based on at least one data packet previously transmitted, and a transmitter configured to transmit the data packet.

Apparatus and method for processing header compressed packet in electronic device

Disclosed are a method and apparatus for packet communication using header compression. The method includes applying a header compression protocol to generate a packet to be transmitted, determining whether the packet is dropped in a transport layer, and transmitting, if it is determined that the packet is dropped, a full packet having an uncompressed header.

Method and apparatus for packet communication using header compression

A method for retaining a Robust Header Compression (ROHC) state in a User Equipment (UE) during switching from a Voice over Long Term Evolution (VoLTE) call to a video call or vice versa is provided. When the VoLTE call is in progress and if a user switches the VoLTE call to the video call, then the RTP header information is sent to an Application Processor (AP) from a Communication Processor (CP). The ROHC compressor continues the compression of the RTP packets using the existing built context for the video call. Further, when the video call is in progress and if the user switches the video call to the VoLTE call, then the RTP header information is sent to the CP from the AP. The ROHC context is reused by exchanging the RTP header information between the AP and the CP.

Method and device for retaining robust header compression (ROHC) compressor state

A method and system is provided for optimizing Radio resources during a VoLTE call when ROHC is enabled by indicating an IP-ID value using an identifier in an Initial and Refresh (IR) packet. During the VoLTE call, when value of a static IP-ID is zero, the ROHC compressor appends an identifier in the IR packet and enables the identifier for indicating the static IP-ID value to the ROHC decompressor. Further, the ROHC compressor sends the IR packet to the ROHC decompressor by enabling the identifier for indicating the static IP-ID value during the ROHC context. The ROHC decompressor receives the IR packet and determines the identifier in the IR packet. If the identifier is enabled in the IR packet then the ROHC decompressor sets the IP-ID value as zero during generation of decompressed IP header.

Method and system for optimizing radio resources between UE and ENB during VoLTE call

A mobile terminal for supporting Rich Communication Suite (RCS) and Voice Over Long Term Evolution (VoLTE) based services is provided. The mobile terminal includes an application processor that enables a first layer of a first session connection protocol stack and transmits signaling for an RCS service to a modem processor; and the modem processor that comprises a second session connection protocol stack for connecting a session, and that transmits, to a communication network, the signaling for the RCS service transmitted through the first layer.

Method and apparatus for controlling power output from an electronic device to an external electronic device

A method of controlling a User Equipment (UE) in a mobile communication system and a communication device in the UE are provided. The method including determining whether a first waiting time related to a call interruption event in a first call mode is exceeded; if the first waiting time is exceeded, transmitting a Session Initiation Protocol information (SIP INFO) message for switching the first call mode to a second call mode to an external device; and switching a call mode of the UE to the second call mode based on a response message in response to the SIP INFO message.

UE in mobile communication system and method of controlling same

Methods, systems, and apparatuses (including, but not limited to, User Equipment (UE) and Base Stations) for a UE to control a packet header compression function in a communication system are described. In one method, if a predetermined condition is satisfied while the packet header compression function is enabled, the UE transmits a request for disabling the packet header compression function to a Base Station (BS), and, if a response is received from the BS, the UE disables the packet header compression function.

Method and apparatus for controlling header compression function of terminal in a communication system

A method and a system for handling audio packets in a Voice over Long Term Evolution (VoLTE) call by a User Equipment (UE) when Robust Header Compression (ROHC) is enabled are provided. The Transmission Control Protocol/Internet Protocol (TCP/IP) layer provides the VoLTE call properties to the ROHC compressor. The TCP/IP layer receives the audio packets from audio engine and sends the Real-time Transport Protocol (RTP) packets to a ROHC compressor. Further, the ROHC compressor compresses the Internet Protocol/User Datagram Protocol (IP/UDP) headers and a RTP header. The ROHC compressor sends the compressed RTP data along with a payload to the network in the UpLink (UL) data path. During DownLink (DL) data path, ROHC decompressor receives compressed ROHC packet from network. The ROHC decompressor ignores the construction of IP/UDP headers for the compressed data.
