Abstract: A method for determining location technology supported by a wireless communications network including sending (505) a location request, for example a MO-LR request, from a mobile wireless subscriber device to the network, receiving a network response (515) in reply to the location request, determining the subscriber device location technology supported by the network from the network response (535, 550), and in some embodiments the location technology of the subscriber device is controlled based on the technology supported by the network.

Abstract: A method and apparatus i) permit the mobile to set and adjust thresholds that control when and how the mobile reselects a cell, ii) enable the mobile to predict the likelihood of cell reselection and iii) enable the mobile to notify the network when a reselection is highly likely during the course of a packet data transmission, which in turn enables the network to take appropriate action in the assignment of a new cell on which to continue packet data interchange. Alternatively, such reselection may be communicated to a virtual bearer for use in controlling a queue.

Abstract: A mobile communication device, and a method of operating a mobile communication device, includes storing at least one frame of a communication signal received from a network, and applying flow control to the lower layers to support network reselection. According to one aspect of the invention, a message is transmitted indicating that a virtual bearer mode of operation is supported by the mobile communication device. The mobile communication device selectively operates in the virtual bearer mode depending upon the response received following such transmission. Additionally, flow control may advantageously be dependent upon detecting that a cell change is imminent.

Abstract: Methods and apparatus for simultaneous independent voice and data services using a remote subscriber identity module (SIM) are disclosed. The methods and apparatus described herein allow a personal computer (or other data station) which does not contain a SIM card and a mobile phone (or other voice station) which does contain a SIM card to cooperate wirelessly to allow the personal computer to use the SIM card in the mobile phone in a virtual manner. As a result, the personal computer may transmit and receive packet-switched data at the same time the mobile phone is transmitting or receiving a circuit-switched voice signal without interference between the two simultaneous transmissions.

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: Architectures and methods architectures for providing real-time cost information to communications applications, for example for transactions conducted by mobile wireless communications devices before the transaction is conducted. In one embodiment a communication transaction is selected at user equipment (UE) (302), a transaction cost request is communicated (304) from the application is to a communication server (306). In response, the server communicates (308) a firm or estimated cost to the UE. The cost may be based on subscription profile information obtained (312) from a source (314) and/or from information obtained (316) from a content provider (317). In some embodiments, the UE accepts or declines to conduct the transaction based on the cost.

A control stack (305) organizes the data within frames during the transmission of data, and an adjustment module (324) adjusts a size of the frames prior to detection that a second cell of the plurality of cells is a candidate for reselection.

Abstract: 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.

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 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.

The first authentication application unit transmits a first synchronization command (500) to the server device over the packet data network (424), and the second authentication application unit generates a user unit code and transmits (502) the generated user unit code to the client device over the packet data network in response to the first synchronization command. The first authentication application unit and the second authentication application unit store the generated user unit code, and the server device transmits a message (508) that includes a control command and the user unit code stored in the second authentication application unit to the client device over the packet data network.

Abstract: A method and apparatus enabling a mobile user device (102) to anonymously access a network (108, 114) in circumstances where access to the network is prohibited that includes an interim identity generator (138), positioned in the mobile user device, generating an interim international mobile subscriber identity (IMSI) in response to access to the network being prohibited. The interim IMSI is utilized for signaling exchanges requiring information corresponding to a SIM card (142) when access is prohibited. A user identity module (152, 154) detects the presence of the interim IMSI in a signaling message, and routes the signaling message to a first home location register (156), in response to the signaling message including the interim IMSI, which then computes and transmits an authentication triplet to the mobile user device. The user identity module routes the signaling message to a second home location register (150) in response to the signaling message not including the interim IMSI.

Abstract: A communication system includes grouping a plurality of mobile stations into a plurality of groups of mobile stations, and assigning a power control range to each group of the plurality of groups of mobile stations, thereby, creating a plurality of power control ranges corresponding to the plurality of groups of mobile stations. Each power control has a minimum and maximum power level. As such, in GPRS mode, all mobile stations with multi-slot-classes that share at least one common time slot and are located in proximity of each other with similar downlink power control requirement may be assigned a power control range for adequate downlink signal reception. The mobile stations grouped in one group are required to monitor all time slots defined in their multi-slot-class for detection of data in the USF field or data field.
