A system and method of simultaneously conducting a data transfer and a voice call between a mobile station and a radio telecommunications network having a mobile switching center (MSC) which serves the mobile station. A first embodiment includes a landline digital simultaneous voice and data (DSVD) modem associated with the mobile station which generates DSVD source signal and line negotiation protocols. The DSVD source signal and line negotiation protocols are encapsulated into circuit mode Radio Link Protocol (RLP) signals and transmitted to the MSC. An interworking function (IWF) associated with the MSC translates the circuit mode RLP signals into signals in a landline telecommunications protocol. In another embodiment, the voice call is carried over the air interface from the mobile station to the network in one timeslot, and the data transfer is carried in at least one additional timeslot on the same voice channel. In other embodiments, two voice channels may be allocated to the same mobile station. The voice call to a first party is carried from the mobile station to the network on one voice channel, and the data transfer to the first or a second party is carried on the second voice channel. The MSC hands off the two voice channels together, but releases them individually when either the voice call or the data transfer is completed.

An apparatus, computer readable medium and method for communicating over a telecommunications network, such as the Internet, with a provider of a service, such as a business. A method for communicating over a telecommunications network with a local representative of an entity, comprising the steps of: receiving, over a data telecommunications network, a request for a connection with a local representative of an entity from a subscriber, wherein the data telecommunications network supports simultaneous voice and data connection over a single line from the subscriber to an Internet Service Provider (ISP) site; determining the geographical location of the subscriber; translating the request from the directory listing database a local representative of the entity that is the geographically nearest to the subscriber requesting a connection; and establishing a voice connection between the subscriber requesting the connection with the local representative of the entity.

A method and apparatus for transport format selection in a mobile wireless communication device. During a simultaneous voice and data call, the mobile wireless communication device selects a transport format for proper uplink data transmission. Simultaneous voice and data calls require higher uplink transmit power than voice only calls. The mobile wireless communication device selects a transport format based on the uplink transmit power level. At higher transmit power levels, minimum or zero data rates are chosen to maintain sufficient power for simultaneous voice. Transmit format is specified using a transmit format combination indicator.

Systems and techniques for receiving facsimile transmissions through a mobile device and simultaneously or subsequently transferring facsimile data to a remote device for storage, printing or other uses are described. A mobile telephone establishes a voice connection to a facsimile transmission device and receives facsimile data through the voice connection. The facsimile data may be buffered for immediate transfer to a remote device or stored for later retrieval and transfer, depending on preprogrammed options or user selections. When the facsimile data is to be transferred, a packet data connection is established between the mobile telephone and the remote device to which the facsimile data is to be transferred and the facsimile data is transferred to the remote device over the packet data connection. Reception of incoming facsimile data over the voice connection and transfer of the facsimile data over the packet data connection may occur substantially simultaneously, or transfer of the facsimile data may be delayed, according to user preferences.

A system and method for communicating data assigns priorities to different types of traffic based on one or more system conditions. The method includes classifying different kinds of traffic, allocating a priority to each kind of classified traffic, and when data received including different kinds of traffic multiplexing the traffic and the received data and transmitting the data according to the allocated priority. The traffic may be classified into signaling traffic, data traffic, and voice traffic. The data traffic may further be classified as follows: an RLP control frame, an RLP new frame, as well as other RLP frames. The voice traffic may be classified as full-rate voice traffic, half-rate voice traffic, quarter-rate voice traffic, and eighth-rate voice traffic. The method may be further controlled based on the type of multiplexing to be performed. Through this system and method, it is possible to provide good quality SVD (service simultaneous voice and data) by avoiding interruptions in transmissions.

Controlling non-simultaneous voice and data connections between a mobile wireless device and a wireless network is described. Following a voice connection origination failure between the mobile wireless device and the wireless network, the mobile wireless device sends a voice connection redial request only after closing an existing data connection between the mobile wireless device and the wireless network. The mobile wireless device tunes a wireless transceiver to a second voice connection channel radio frequency that differs from a first data connection channel radio frequency and establishes a voice connection with the wireless network on the second voice connection channel radio frequency.

A wireless method, apparatus, and system provide simultaneous transacting of voice and data on adjacent timeslots through a combination of channel access rules and sacrificing small audio portions when required. This includes wirelessly operating on at least two timeslots which are adjacent to one another, operating voice on a first timeslot of the at least two timeslots and monitoring a second timeslot of the at least two timeslots for data, and, responsive to a data transmission request and receiving voice on the first timeslot, discarding a portion of the voice in the first timeslot to provide a larger guard time for programming between the first timeslot and the second timeslot and transmitting data in the second timeslot based on the data transmission request.

A system and method of controlling the Radio Access Technology selected by a vehicle telematics unit includes receiving a request to initiate a voice call from a vehicle occupant at the vehicle telematics unit; ending any existing data connection that is using a latest-technology RAT to communicate with a cell tower, wherein simultaneous voice and data (SVD) communications are not possible using the latest-technology RAT; ending the data connection with the cell tower using a latest-technology RAT; establishing the voice call via a cell tower using an older-technology RAT; detecting the end of the voice call; commanding the vehicle telematics unit to end use of the older-technology RAT in response; and establishing data communications with a cell tower via the latest-technology RAT.

The present invention relates to an audio controlling method of data service and a mobile communication terminal thereof, particularly to a method for controlling a video on demand (VOD) service audio in the situation of simultaneously providing voice services and high-speed data services. The object of the invention is to provide a method for controlling audio according to the VOD which generates a voice call when using the Simultaneous voice and data (SVD) service which simultaneously provides the voice and data communication as well as providing the voice service and the high-speed data service. Another object of the invention is to provide an audio controlling method of the VOD capable of preventing the overlap of the VOD audio and voice call in a 1xEvolution Data and Voice (1xEV-DV) system when using the SVD service simultaneously supporting audio and data communication.
