A communication system including a mobile station () sending a plurality of uplink radio link control data blocks () to a base station () in an uplink temporary block flow (), and receiving a plurality of downlink radio link control data blocks () from the base station in a downlink temporary block flow (). The communication system includes a protocol control unit () within the base station, having a base station medium access control layer () that sends an identifier during setup of the downlink temporary block flow (), and sends an uplink state flag indicating channel availability in a first one of the plurality of downlink radio link control data blocks (). A GPRS/EDGE subsystem () is located within the mobile station, having a mobile station medium access control layer () that receives the identifier and the uplink state flag, and sends uplink data in a first one of the plurality of uplink radio link control data blocks () to the base station in response to the uplink state flag indicating channel availability. The base station medium access control layer sends a directed acknowledgement in a subsequent one of the plurality of downlink radio link control data blocks () in response to receipt of the uplink data from the mobile station, and the mobile station sends uplink data in a second one of the plurality of uplink radio link control data blocks () in response to the directed acknowledgement.

Method for rapid uplink access by GSM GPRS/EDGE mobile stations engaged in voice over internet protocol packet transfer mode

A mechanism for notifying a mobile station of receipt of a packet-switched paging message in a GSM communication system. A base station controller ( ) sends the packet-switched paging message to the mobile station ( ) along a main dedicated control channel in response to the mobile station being capable of operating in a dual transfer mode and being currently engaged in circuit-switch voice interchange activity, resulting in a simultaneous voice and data transmission in dual transfer mode.

Method for enabling receipt of a packet-switched page by a mobile station

A receiver automatic gain control includes a variable gain receiver having a control input and responsive to a gain control signal for adjusting the output level of the receiver. A controller is coupled to the variable gain receiver. The controller monitors a received signal quality and a received signal power level. The controller generates a control signal for controlling the gain of the variable gain receiver as a function of the signal quality and the power level. The controller controls the gain as function of the received signal power level and selectively controls the gain as a function of the signal quality.

Automatic gain control for a receiver and method therefor

A method for sending acknowledged transport data between a mobile station ( ) and a base station system ( ) in a GPRS system ( ) in which a protocol control unit ( ) counts the number of data blocks in an acknowledgement message sent by the mobile station in response to a data packet transmission. A heuristic is then defined, based on the number of data blocks counted, and the number of corresponding data blocks corresponding to a subsequent data packet transmission is compared with the heuristic to determine that a virtual acknowledgement channel is being requested when the number of corresponding data blocks in the subsequent packet data transmission is less than the heuristic.

Method for supporting acknowledged transport layer protocols in GPRS/edge host application

An unacknowledged, reliable short message service cell broadcast message reception protocol method to enable short message service cell broadcast messages to be constructed from the fragments of the multiple repetitions of the cell broadcast service messages which are repeated on the cell broadcast channel. When a new message block, corresponding to a recognized type of cell broadcast service message, is geographically coherent with existing partially received data or contains message components previously received, and is temporally coherent with previously received message blocks, the new message block is inserted within a received message structure. If the received message structure is complete and correctly received, the complete message is assembled and sent to an upper software layer.

Method for receiving SMSCB messages during GPRS/EDGE data transfer mode

A radiotelephone device receiving network information, transmitted along a radio channel, from a network includes an acknowledgement coordination module determining a mode for exchange of acknowledgement information with the network. The radiotelephone device transmits the acknowledgement information to the network through a main dedicated control channel, using a defined service access point identifier corresponding to transmission of the acknowledgement information through the main dedicated control channel, in response to the mode for exchange of acknowledgement information being the main dedicated control channel. The radiotelephone device transmits the acknowledgement information to the network using a temporary block flow acknowledgement interchange in response to the mode for exchange of acknowledgement information being other than the main dedicated control channel.

Method and apparatus for supporting radio acknowledgement information for a uni-directional user data channel

An apparatus enabling multiple client devices to access a SIM card, coupled to a server device, along a local link, that includes a SIM card interface and a router unit. The SIM card interface couples the SIM card to the server device, formats the commands from the client devices for transmission to the SIM card, and formats responses to the commands for transmission from the SIM card to the client devices. The router unit routes the commands from the server device to the SIM card interface, and routes the responses to the commands for transmission along the local link from the SIM card to the client devices. A broadcast message is transmitted by the router unit along the local link to the client devices in response to detecting a physical presence signal transmitted by the SIM card interface in response to the SIM card being coupled to the SIM card interface.

Method and apparatus for remote multiple access to subscriber identity module

A method for universal mobile telephone service synchronization by a mobile station operating in a GSM dedicated mode in a wireless communication system including a mobile station sending voice signals to and receiving voice signals from a base station. A voice activity detector transmits control information indicating detection of voice activity at the mobile station, and an equalizer identifies and processes a training sequence and transmitting corresponding information for the training sequence. A physical layer interface determines whether the mobile station is utilizing discontinuous transmission mode, based on the control information from the voice activity detector, and determines whether the based station is utilizing discontinuous transmission mode, based on the correlation information from the equalizer, and universal mobile telephone service synchronization is performed in response to the mobile station and the base station utilizing discontinuous transmission mode.

Method for synchronizing a mobile station to UMTS while operating in GSM dedicated mode

A simplified version of a defined GPRS/EDGE Class A mobile station that incorporates transmission and reception of GPRS/EDGE data during discontinuous transmission and reception modes on a dedicated traffic channel, and that includes a mechanism for streaming GPRS/EDGE data to and from a packet-switched channel, along with optional association of a voice timeslot with one or more GPRS/EDGE data timeslots. GPRS/EDGE packet data and circuit-switched voice data are simultaneously transmitting along a dedicated GSM voice traffic channel by transmitting the GPRS/EDGE packet data between occurrences of circuit-switched voice data and silence descriptor frame data along a dedicated voice traffic channel.
