摘要： One illustrative method of providing network broadcast information to a wireless device from a wireless local area network (WLAN) includes the steps of receiving, from one or more available cellular networks or a network database, cellular network broadcast information associated with the one or more available cellular networks; providing the cellular network broadcast information in a generic container message which varies in content and format according to one or more cellular standards associated with the one or more available cellular networks; and causing the generic container message to be regularly broadcasted for receipt and use by a wireless device. In an alternative approach, the steps include regularly broadcasting a network interworking indicator which is indicative of whether cellular network broadcast information is available for receipt from the WLAN; receiving a probe request from a wireless device; and causing the cellular network broadcast information to be sent to the wireless device in the generic container message in response to the probe request from the wireless device. The generic container message may alternatively or additionally include wireless network broadcast information from different types of wireless networks (e.g. Wi-MAX) which are available to the WLAN.

摘要： A mobile device may retrieve service information about a network prior to associating with the network. Utilizing an advertisement protocol to transmit service query messages, a mobile device may receive service query responses from a network that identify the services available prior to establishing network capability. In other words, the messaging is prior to the exchange of any authentication parameters between the device and the network as well prior to the establishment of a recognized session between the device and the network.

摘要： A method for network selection on a user equipment (UE) device and the UE device are shown. The user equipment device registers on a first network in a wide area cellular network (WACN) band and receives, from a wireless local area network (WLAN), a list of WACNs that support generic access network (GAN) capabilities. The user equipment device selects the WLAN if the first network is on the list.

摘要： A method for initiating a Packet Switched emergency call using a user equipment (UE) is presented. The UE includes a plurality of protocol layers. The plurality of protocol layers including an IMS sublayer, a non-access stratum (NAS) layer and an access stratum (AS) layer. The method includes generating an ATTACH REQUEST using the UE. The ATTACH REQUEST has an attach type. The method includes retrieving the attach type of the ATTACH REQUEST using the NAS layer of the UE, and generating an RRC CONNECTION REQUEST. The RRC CONNECTION REQUEST includes an RRC establishment cause based upon the attach type of the attach request.

摘要： A method for key agreement between a first party and a second party over a public communications channel, the method including selecting, by the first party, from a semigroup, a first value “a”; multiplying the first value “a” by a second value “b” to create a third value “d”, the second value “b” being selected from the semigroup; sending the third value “d” to the second party; receiving, from the second party, a fourth value “e”, the fourth value comprising the second value “b” multiplied by a fifth value “c” selected by the second party from the semigroup; and creating a shared secret by multiplying the first value “a” with the fourth value “e”, wherein the shared secret matches the third value “d” multiplied by the fifth value “c”.

摘要： A method at a sensor apparatus affixed to a transportation asset. The method includes calibrating the sensor apparatus by initiating a vertical impact at the transportation asset, measuring spring oscillation and creating a model of the transportation asset. The method further includes detecting, subsequent to the calibrating, an impact event at the sensor apparatus. The method further includes measuring spring oscillation due to the impact event at the sensor apparatus and using the measured spring oscillation in the model created during calibration to create a load mass estimate for the transportation asset.

摘要： The present invention provides a system and method of modifying policy settings in an electronic device. An embodiment includes a plurality of access stations, each capable of wirelessly transmitting across a geographic region. A mobile electronic device, capable of roaming between regions is operable to establish a wireless link with the access stations. The device is owned by an office which sets communication policies determining through which access stations mobile device can place voice calls. This policy is stored on an office server as a database and periodically transmitted to the device as the device makes contact with the office server over the internet. Hence, the device maintains a copy of this policy database. When placing a voice call, the device first determines which access station is serving the region it is located in and then determines whether it is allowed to place a call through that access station using its policy database.
