Abstract:
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.
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.
Abstract:
A communication system comprising a mobile station and a network implements a persistent packet data control channel that provides for a continuous exchange of control information, such as system information (SI) messages and handoff-related information. The mobile station implements the persistent packet data control channel by mapping the persistent packet data control channel to a packet associated control channel when a packet associated control channel is available and to a virtual associated control channel when a packet associated control channel is not available. The virtual associated control channel allows the mobile station to pass control information to network in the absence of an uplink Temporary Block Flow (TBF).
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.
Abstract:
A method and apparatus for mitigating the impact of lost data due to cell reselection for mobile stations operating in packet data transfer mode is described. A mobile station may perform cell reselection 2 to 4 times per minute when located in an urban area, even if the mobile station remains stationary. A mobile station moving through a communications network (100) may cross over various cell and routing area boundaries. Further, a mobile station operating in push-to-talk mode may lose up to 8 seconds of data when reselecting a cell in a new routing area. A serving cell transmits an information element (301, 303, 305) in which the mobile station is informed whether cells in its neighbor list are in the same routing area as its serving cell. If the radio link to the serving cell is acceptable then the mobile station avoids reselection to cells outside its serving cell routing area.
Abstract:
An apparatus (100) and method (300, 400) for primary link packet control using a traffic flow template. Primary link traffic flow template filter parameters can be set at a packet control module (120). Incoming packet data can be compared against the primary link traffic flow template filter parameters (340). How the incoming packet data is sent to a wireless device (180) over the primary link can be controlled based on comparing incoming packet data against the primary link traffic flow template filter parameters.
Abstract:
A method in a wireless communications network including receiving (310) a network connection request from a subscriber device having an invalid subscriber identity, connecting (340) the subscriber device, from which the network connection request was received, to the wireless communications network for limited purposes only upon determining (320) that the subscriber device has in invalid subscriber identity in the absence of a limited network connection indicator in the network connection request. In some embodiments, a limited attach message indicates that the attach request is for limited purposes.
