A method for steering of roaming (SOR) in wireless communication networks includes sending by a mobile equipment (ME) a registration message to a visited public land mobile network (VPLMN). The ME receives a first message from a home public land mobile network (HPLMN) through the VPLMN. The ME determines that the first message has failed a security check. In response to determining that the first message has failed the security check, the ME sends a second message to the VPLMN, the second message including an indication that the first message has failed the security check.

Steering of roaming in wireless communication networks

A method at a first computing device providing a local traffic service, the method including detecting a vehicle is transitioning to a region of control of a second local traffic service; and providing, to a second traffic management service, priority information for the vehicle.

Method and system for traffic management

A method comprising transmitting, by a user equipment (UE) to a network node, a registration message comprising at least one of a first indicator configured to indicate emergency call information display capability, a second indicator configured to indicate language information, or a third indicator configured to indicate a status of previously received emergency information, and receiving, by the user equipment from the network node, a registration accept message.

Support of emergency number descriptions

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.

Methods and apparatus for providing network broadcast information to wlan enabled wireless communication devices

A method at a user equipment for obtaining emergency codes using a non-Third Generation Partnership Project (3GPP) network, the method including sending a request message to a network node, the request message containing an indication; and receiving, at the user equipment, a response message, the response message including at least one mobile country code (MCC), and the response message indicating an emergency number, type or category information, wherein the emergency number, type or category information is associated with the at least one MCC, and wherein the at least one MCC indicates a portion of a Public Land Mobile Network (PLMN) code to which the emergency number, type or category information applies.

Method and apparatus for providing emergency codes to a mobile device

Methods and devices for encoding a point cloud. A current node associated with a sub-volume is split into further sub-volumes, each further sub-volume corresponding to a child node of the current node, and, at the encoder, an occupancy pattern is determined for the current node based on occupancy status of the child nodes. A probability distribution is selected from among a plurality of probability distributions based on occupancy data for a plurality of nodes neighbouring the current node. The encoder entropy encodes the occupancy pattern based on the selected probability distribution to produce encoded data for the bitstream and updates the selected probability distribution. The decoder makes the same selection based on occupancy data for neighbouring nodes and entropy decodes the bitstream to reconstruct the occupancy pattern.

Supported extended emergency information type

A method at a computing device within an Intelligent Transportation System, the method including detecting a traffic event at the computing device; determining no fixed roadside unit is available from the computing device; establishing an Internet Protocol connection from the computing device to a network node; and sending a traffic event message from the computing device to the network node, the traffic event message providing information for the traffic event.
