An attention challenge is provided to a user to ensure that while a mobile device is in motion, the user is not operating a vehicle. Failure at the attention challenge results in a restricted set of features so that the user is not able to interact with the mobile device in a manner that would impair driving.

A method for providing a secure transmission of packet data on a plurality of network access modes in a packet data network. The UE-1 comprises a processing module for initiating communication with one or more receiving UE-2, operating a spread spectrum access (SS) middleware for communicating to a service application (SA) server for retrieving available access modes of the one or more receiving UE-2. The processing module retrieves available access modes for the one or more receiving UE-2, randomly breaks up an uplink transmission of packet data on multiple transmissions of packet data on available access modes of the UE-1 and sends packet data of the transmissions on available access modes of the UE-1.

The present invention relates to a text control message for carrying control information from a Wireless Wide Area Network (WWAN) to a terminal in a Wireless Local Area Network (WLAN). The text message has a code for indicating to the terminal that the text message contains control information and a text portion being the control information. A logical node located in WWAN that sends control information to a terminal located in a WLAN. The logical node receives information regarding the terminal from a Wireless Serving Node (WSN) located in the WLAN. The logical node has knowledge of an access point connected to the WSN that currently serves the terminal in the WLAN. The logical node triggers, in a message center of the WWAN, the sending of the text message to the terminal.

An emergency call handling system and method for a cellular telecommunications system. The emergency call handling system is provided with at least one subscriber terminal which upon failure to seize a voice connection to an emergency center for an emergency call, transfers data messages over the digital control channel to the emergency center advising it that the user of this one subscriber terminal has an emergency situation. Advantage is found with the present invention in that in times of radio voice channel and/or network traffic congestion resulting in call set up failure, the information relating to a user emergency can be forwarded as data messages to the emergency center.

In a radio telecommunications network, a system and method of providing service differentiation for call forwarding based upon the type of call. The system provides network support that allows the forwarding of calls of different types to appropriate devices for each type of call, as identified by the call's service code. The system determines whether a call to a mobile station is a data call, and if it is a data call, provides the network support for forwarding the call to a different number than voice calls. A Service Type parameter is added to ANSI-41 signaling messages to inform various nodes in the network of the type of call. The network includes a home location register/service control point (HLR/SCP) with a database of call forwarding (transfer) numbers for its served mobile stations. The database records at least one transfer number for each type of service. Service logic in the HLR/SCP associates the type of call with the appropriate transfer number. In this manner, incoming data calls such as G3Fax calls are forwarded to an alternate fax machine, a fax mailbox, or some other device capable of storing the data rather than a voice mailbox. The system and method are applicable to forwarding any type of data service, and are not limited to ADS and G3 Fax calls.

Embodiments herein include a method performed by an intermediate proxy node via which client devices request data resources from a data resource server. The data resources are organized into different data resource collections. The method includes receiving a request for a subset of a data resource collection and, responsive to receiving such a request, determining that the collection is not stored in a request-agnostic cache maintained by the proxy node. Responsive to this determination, the method further entails retrieving the collection from the data resource server. The method then includes extracting the requested subset from the retrieved data resource collection and selectively returning that subset as a response to the request. Finally, the method entails storing the data resource collection in the request-agnostic cache for serving other requests for data resources in the data resource collection, including a request for a different subset of the data resource collection.

A method and a Packet Data Service Node (PDSN) of restricting geographical use of a service for a mobile terminal (MT) in a packet data telecommunications network. The PDSN receives from an access node (AN), a registration request message having a cell information for requesting. The PDSN translates the cell information into a zone ID, stores the zone ID in a first table and sends to a AAA server, an access request message for authenticating the MT. PDSN further receives from the AAA server, an access accept message for authorizing the MT to receive packet data service, wherein the access accept message includes an allowance information. Afterwards the PDSN compares the allowance information with the zone ID. If the allowance information is different from the zone ID in the first table, the PDSN set up a filter for the MT and rejects packet data for the requested packet data service.
摘要:
Procedures are disclosed for supporting roaming subscriber mobile station access to stored subscriber data messages. In one aspect, a received subscriber data message is routed for storage and subsequent forwarding/retrieval, not to a “home” message center, but instead to a message center either optimally positioned with respect to a current known location of the subscriber mobile station or associated with an initially receiving mobile switching center. In another aspect, a mailbox established for a given subscriber mobile station in the home message center is transferred (perhaps on a periodic basis) for storage in a local mailbox of a proximate message center within a cellular telephone network where the subscriber is currently roaming. In either case, the storing message center thereafter performs any requisite operations needed to facilitate message forwarding to or retrieval by the addressee subscriber mobile station.

A number of different mechanisms are proposed for effectuating the delivery of digital data messages to mobile stations which have currently selected an analog control channel. In one method, a signal is sent to the mobile station instructing it to make a server reselection and choose the best available digital control channel. Once the reselection is accomplished, the digital data message is delivered in a conventional manner using the digital control channel. In another method, the digital data message is reformatted for analog delivery, and the reformatted message sent over either the analog control channel or a selected analog voice channel. In yet another method, a call connection is made with the mobile station over a voice channel, and a synthesized audible message corresponding to the digital data message is transmitted over the voice channel after the subscriber answers the call. In instances where message delivery over the control channel is interrupted due to mobile station roaming, a forced re-registration occurs following the new server reselection, thus triggering continued message delivery over the new control channel.
摘要:
An interface between a dual mode mobile station and a piece of data terminal equipment supports both a logical digital interface and a logical analog interface, with the analog interface passing through a modem. At set-up of either a mobile originated or mobile terminated data/fax call, a supporting dual mode communications network determines whether a digital traffic channel is available on an air interface. If so, the channel is allocated to the mobile station, and data/fax communication with the data terminal equipment occurs using the logical digital interface. Otherwise, an analog voice channel is allocated, and the data/fax communication with the data terminal equipment occurs using the logical analog interface and modem. Within the supporting network, data/fax communications via the digital traffic channel are routed through an interworking functionality that terminates a radio link protocol utilized for communicating over the digital air interface. Analog voice channel data/fax communications are instead routed through a modem pool that terminates a selected modem protocol utilized by the modem for communicating over the analog air interface.
