摘要:
A method and mechanism to allow a location server to initiate a user plane location service (e.g., SUPL defined by OMA) procedure to a user plane enabled device via Instant Messaging, or alternatively, via an existing SIP session if a multimedia session is already established. The location request is signaled to the user plane enabled device via a SIP INFO message. The location request uses SIP messaging to overcome firewall and other network security issues. Location using SUPL over SIP may be provided about a caller making an E911 emergency call. An Instant Message may be sent to the user plane enabled device, e.g., a VoIP wireless phone.

摘要:
An N-dimensional affinity confluencer comprises an affinity table to maintain a plurality of affinities for each of a plurality of wireless devices. A sphere of influence (SPIN) table provides an influence for determination of a confluence between affinities maintained in the affinity table. An affinity confluence determination module determines an affinity confluence between the plurality of wireless devices and an influence parameter associated with the sphere of influence (SPIN) table. An affinity confluence is determined from among a plurality of wireless devices by determining a confluence of at least two predefined affinities from among a plurality of wireless devices. A sphere of influence parameter is applied to the confluence to determine those of the plurality of wireless devices defined by an affinity confluence. The plurality of wireless devices need not be within a common communication network.
摘要:
A technique to allow a server such as a location server to throttle concurrent or closely timed location requests for the position of a given wireless device such that within a certain time period preferably only one location request will be initiated to the positioning engine and the remaining closely-timed location requests will be buffered or cached. When a position for the given wireless device is returned per the outstanding location request, then the retrieved position will be used to respond to each of the buffered location requests. Thus, a plurality of location requests are satisfied with a single request to the positioning engine. By optimizing the use of cached position requests, throttling of location requests per the invention reduces network traffic significantly, increases the efficiency of a positioning server (therefore reducing business cost), and provides for an improved grade or quality of location based services in general.
摘要:
A protocol converter or translator between ANSI-41 ORREQs and VoIP V2 messaging. The protocol converter may alternatively (or also) provide conversion between GMS MAP and VoIP V2 messaging. Interaction of VSPs with a Mobile Positioning Center (MPC) or a Gateway Mobile Location Center (GMLC) is permitted, as is interaction of wireless carriers with a Voice Positioning Center (VPC). In this way existing GMLCs or MPCs may be used to service VoIP 9-1-1 calls. Moreover, operators of Voice Positioning Centers (VPCs) who implement wireless offerings can re-use their existing VPCs to service wireless 9-1-1 calls.
摘要:
A prank call server that performs 911 prank call filtering over a 911 emergency call system, prior to routing a 911 call to a PSAP. The inventive prank call server identifies prank calling devices, regardless of current service subscription, by retrieving and analyzing emergency call data pertaining to detected prank 911 calls. The prank call server assigns a unique global identifier to each 911 call detected on the 911 emergency call system. Unique global identifiers enable a PSAP to uniquely identify prank 911 calls that are identified thereon. A PSAP transmits a prank call signal and a relevant unique global identifier to the prank call server, for each prank 911 call that is detected. A prank call signal/unique global identifier combination triggers the prank call server to store all available call data for a referenced prank 911 call in to a prank call database, for subsequent prank call filtering analysis.
摘要:
An emergency services key (e.g., ESQK or ESRK) is guaranteed to be available from a limited size ESQK pool. A plurality of ESQKs are grouped into a pool of emergency service keys “ESQK Pool ID”, each including anywhere from 1 to N number of ESQKs. Each ESQK preferably has a “Timestamp”, information relating to the specific emergency E911 call (“Call Data ID”), a guard timer, and an optional hold timer. The ESQK having a Call Data ID=“NULL”, and having the oldest Timestamp, is chosen for selection. If no such ESQK has both Call Data ID=NULL and the oldest Timestamp is found, then the ESQK with merely the oldest Timestamp is selected. The timestamp is reset to a current time plus a guard timer, or hold timer if desired.

摘要:
A method and apparatus for supplying greater fluid flow and/or fluid volume from a fluid provided from a facility source to a substrate processing chamber is provided. The apparatus couples to an existing facility fluid source and accumulates the fluid, and the flow characteristics of the accumulated fluid are enhanced for delivery to the processing chamber. The apparatus includes a tank in fluid communication with the facility source and one or more processing chambers, and a valve disposed between the tank and the processing chambers adapted to receive a signal from a controller to facilitate filling or draining of the tank. The apparatus and method affects cost of ownership by altering the pressure and/or volume of the existing facility source without the need to alter the facility source.
