摘要:
An ALI/ESME steering gateway bridges the nationwide ALI/ESME network notes (or PSAPs) with the GMLC/MPCs of various different XPC networks. The steering gateway provides a unified interface between the PSAP/ALI network and positioning centers (GMLC/MPC/VPCs). Using the steering gateway, an E911 service provider accesses positioning centers (GMLC/MPC/VPC) of any XPC network. This access by the ALI to the positioning center is accomplished with any type of interface, irregardless of the protocol type. The connectivity of each virtual communication path between ALIs and PSAPs is managed. The ALI/ESME steering gateway also provides translation of the protocols between the two ALI-MPC interface sets (inbound and outbound). The ALI/ESME steering gateway also consolidates (or “de-duplicates”) any/all duplicated requests from a same ALI or PSAP for the same emergency call so that only one request is then sent to the destined positioning center within the relevant network.

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.

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.

A location verifier can be configured to receive a location report of a target mobile device, wherein the location report includes data characterizing a location for the target mobile device. The location verifier can also be configured to receive a list of mobile devices that are within a predefined proximity of the target mobile device. The location verifier can further be configured to interrogate each mobile device in the list of mobile devices for a list of detected devices. Each device in the list of detected devices can be detected through peer-to-peer communications.

A wireless device Location Services Agent (LSA) provides location functions such as reporting locations to a Location Agent Management Module (LAMM) function in a location services gateway (LSG). The LSA provides a consistent location protocol for providing single shot, periodic triggers and area event triggers. Actual position determination is performed by the native techniques supported by the handset. Location is setup via a Location Agent Management Module (LAMM) component of a Location Services Gateway (LSG) communicating with the LSA. The LSA provides for agent upgrade; SET (handset) registration to the LAMM; Single Shot location determination and conveyance to the LAMM; Periodic Triggered location; Area Event Location; and Privacy Notification and Verification. The LSA interfaces with the LAMM component of the LSG to initialize location requests, and interfaces with external location servers for actual position determination.
摘要:
A technique evaluates overlapping request intervals, and from them determines a temporal reporting interval that satisfies requirements for all that overlap. The temporal reporting interval represents a temporal trigger used to best support multiple triggers on the same target, without modification or support by the target mobile. Disclosed embodiments relate to an example of location requests wherein multiple users, by chance, request location triggered services on the same target mobile during the same time period. To minimize the usage of mobile and network resources, the present invention reduces the number of active triggers on a target mobile subjected to multiple requests (e.g., location requests from multiple tracking applications).

摘要:
The number of messages required in networks where both location and presence services are deployed may be reduced, by retrieving presence data from messages otherwise intended to provide only location information. Thus, information determined in a location service scheme is utilized to provide a presence service as well. A location server requests mobile subscriber (MS) information from a Core Network (CN) Node (i.e. HLR, MSC, etc.) that can be used in determining the Location of the MS. A single message aggregates retrieval of information for two services, specifically, for both location and presence.
