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 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

An apparatus and a method for generating an Automatic Repeat reQuest (ARQ) feedback message in a wireless communication system are provided. The method includes generating first feedback information of at least one ARQ block, determining whether any ARQ blocks include at least one successfully received ARQ sub-block, when the at least one erroneous ARQ block includes at least one successfully received ARQ sub-block, adding second feedback information of the ARQ sub-blocks to the first feedback information of the ARQ blocks using a field indicating whether the second feedback information is added and a field indicating the erroneous ARQ blocks including the at least one successfully received ARQ sub-block, and sending the first feedback information with the second feedback information added, to the transmitting stage.
