Abstract:
A method for sending acknowledged transport data between a mobile station (202) and a base station system (208) in a GPRS system (200) in which a protocol control unit (214) 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.
Abstract:
A mechanism for notifying a mobile station of receipt of a packet-switched paging message in a GSM communication system. A base station controller (108) sends the packet-switched paging message to the mobile station (116) 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.
Abstract:
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.

Abstract:
An apparatus (100) and method (200) for enabling a wireless communication device operating during access class restrictions to receive an incoming emergency call for a predefined time period are provided. After the wireless communication device (100) makes an emergency call to an emergency service center such as police (216), the wireless communication device (100) is enabled to respond to a return call from the emergency service center (218). The wireless communication device accepts the return call based upon the emergency access class information (408) and the priority level (410) of the return call.
Abstract:
A radiotelephone device receiving network information (Fig. 4) receives a mode for exchange of acknowledgement information determined and transmitted from a network acknowledgement module (steps 300 and 302). The radiotelephone transmits the acknowledgement information with to the network through a main dedicated control channel (step 304) in response to the mode information. Otherwise the radiotelephone device transmits acknowledgement using a temporary block flow acknowledgement interchange in response to the mode being other than the main dedicated control channel (step 308, 310, and 312).
