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.

Simultaneous transmission of voice and data over the voice channel of a wireless communications network, such as a “cell phone” network, is reconfigurable on the fly among multiple operating modes, including a lull detection mode in which data is transferred during a lull or quiet period in the voice content. Additionally, control signaling in the voice channel, rather than over a separate control or “overhead” channel is employed to support SVD. The described system operates transparently over any wireless telecommunications system.

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.

A gateway enables point to multipoint connectivity from voice, data, or SVD clients over voice and data networks. The gateway connects one or more known voice networks (e.g. telephone networks) and one or more data networks (e.g. LANs, WANs, and internet) so that clients on either network may access any of the networks via various devices like analog telephones, data modems, SVD modems, or direct data network connections (e.g., ethernet, token ring). The gateway has connections to both the data network(s) as well as the voice network(s). The gateway is capable of splitting a signal with both voice and data streams and routing either and / or both of these streams over the voice network alone, the data network, or both. A process, executing on the gateway enables the gateway to establish connections on gateway paths and to control and direct a flow of voice and data information between the destinations on these networks.

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 measurement report message that indicates a set of active base stations (BSs) of voice call connection in the second system is generated. And the measurement report message is transmitted to a serving BS of the data call connection in the first system.

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.

A method of invoking and cancelling voice and data service between a mobile unit and a base station. Using a standard telephone system, the connection for a voice service and a data service is the same. With the introduction of the digital wireless link, the voice connection and the data connection are different. Therefore new dialing commands which indicate the intent of the connection are created. These commands can also be used to designate the intent of the call from a mobile unit capable of data and voice service but not capable of simultaneous voice and data service. They can also be used to invoke simultaneous voice and data services.
