A Secure Location Session Manager (SLSM) is an intelligent router for open mobile alliance (OMA) Secure User Plane Location (SUPL) Version 1.0 (and later) messages best implemented when multiple, geo-diverse SUPL servers are deployed in a distributed environment, such as an active-active redundant configuration within a wireless carrier's network. In a standalone option, the SLSM acts as a 'middleman' for all SUPL positioning messages between a mobile device and a responsible SUPL server. In an embedded option, the SLSM resides within an existing server. The SLSM manages and stores session information for all pending and ongoing SUPL positioning sessions in internal tables for routing and load balancing purposes. The external interfaces of the SLSM consist of OMA ULP messages.

Secure location session manager

A technique and apparatus to provide status tracking of presence and/or location of wireless devices to requesting entities inside and/or outside a particular wireless system. Presence and/or location information is provided to entities outside a particular servicing wireless network via mechanisms of call processing components of a mobile network and standard mechanisms available to any appropriately conforming MSC element. In one embodiment, a wireless chat automatic status tracking system utilizes a change in mobile registration status to automatically forward or copy a registration notification (REGNOT) message to an external IP application, to notify a chat group system outside the wireless network of current status information activity regarding a relevant device. Change in mobile registration is communicated via a suitable signaling link between a HLR and the chat group system. REGNOT messages are pushed over TCP/IP connections to external applications to automatically notify the external system of a particular user's location.

Wireless chat automatic status tracking

A technique and apparatus to provide status tracking of presence and/or location of a mobile, wireless device to a requesting entity even outside of a particular wireless system. This allows wireless service providers the ability to monitor and log changes in the status of mobile stations within and/or outside their networks. Embodiments are disclosed wherein presence and/or location information is provided to entities outside of a particular servicing wireless network using the mechanisms of call processing components of a mobile network (e.g., call setup procedures), and using standard mechanisms currently available to any appropriately conforming Mobile Switching Center (MSC) element. A mobile activity status tracker (MAST) is disclosed which contains a database of information similar to the information contained in the Home Location Register. The MAST tracks and reports status and activity of mobile wireless devices in a wireless network using mobile registration message, mobile inactivity message forwarding, and/or mobile automatic notification of subscriber status to TCP/IP entities (e.g., application servers on the Internet or Intranet). The MAST system duplicates the same or similar information contained in a corresponding HLR, but is available as an external database entity which is not restricted by SS7 standards. The tracking need not track call-specific information, e.g., called telephone numbers or information regarding conversations sustained by the tracked wireless subscribers.

A location privacy configuration module enables location determination to emergency services only relating to an emergency text message or emergency text message session. An emergency text message transmitted to an emergency number is routed to an emergency text message server, which initiates an emergency text indicator for each emergency text message, and requests location information for the emergency texting device by transmitting the emergency text indicator and a location request to a location determination server. Location of the emergency texting device may be obtained without acquiring customer authorization for location determination. The originating text messaging device acknowledges receipt of the emergency text indicator/location request combination and checks the location privacy setting configured thereon. Location determination is permitted if configured to permit location determination if emergency text messaging.

Location based wireless services in a service provider's network are intertwined with a message database (text and/or audio) to automatically provide location information regarding the subscriber to the message database, without requiring the wireless device itself to provide the location information. A location management system is provided to perform the location management functions of determining subscriber location (e.g., by call/sector ID, angle of arrival (AOA), time difference of arrival (TDOA), time of arrival (TOA)), and of mapping the location to the desired text and/or audio. Speed information may also be determined by the location management system, or the subscriber may be prompted to input a particular mode of transportation, or generally indicate their speed. Of course, the slower the speed of the subscriber, the fewer location updates will be required, lessening the burden on the tour guide system in the wireless network.

A prepaid messaging solution that uses open networking standards and supports pre-payment of enhanced Internet messaging services. The prepaid messaging solution accurately determines if a subscriber has sufficient account balance to deliver a complete short message, prior to message delivery. Message delivery is prevented if insufficient funds are in the subscriber's account. A prepaid tariff engine, preferably extensible over a TCP/IP network, supports remote interaction with the SMSC and web chat servers to apply a real-time billing charge for each message. A service provider may create subscriber classes of service that define subscriber rates and/or tariffing plans used to apply real-time billing charges for sending/receiving messages. The prepaid short message tariff engine determines the appropriate message billing based upon, e.g., flat rate per message, character count, Time of Day, etc. The prepaid short messaging service preferably supports Internet web page access to subscriber's short messaging account balances and account status.

Wireless chat automatic status signaling

A technique and apparatus to provide status tracking of presence and/or location of a mobile, wireless device to a requesting entity even outside of a particular wireless system. This allows wireless service providers the ability to monitor and log changes in the status of mobile stations within and/or outside their networks. Embodiments are disclosed wherein presence and/or location information is provided to entities outside of a particular servicing wireless network using the mechanisms of call processing components of a mobile network (e.g., call setup procedures), and using standard mechanisms currently available to any appropriately conforming Mobile Switching Center (MSC) element. In one disclosed embodiment, a wireless chat tracking system is implemented which utilizes a change in mobile registration status to automatically notify a chat group system outside the wireless network of current status information activity regarding a relevant device, e.g., registration activity or inactivity timeout. In the wireless chat automatic status tracking system, a registration notification (REGNOT) message is either explicitly forwarded or copied to an external IP based application (e.g., to a mobile chat group system). The change in mobile registration is communicated via a suitable signaling link (e.g., SS7, TCP/IP, etc.) between a Home Location Register (HLR) and the chat group system. Therefore, instead of a conventionally closed system using SS7 messages, REGNOT messages are pushed out over TCP/IP connections to external applications (e.g., chat servers) to automatically notify the external system of the location of a particular user.

A prepaid messaging solution using open networking standards (e.g., TCP/IP) to support pre-payment of Internet messaging services. The disclosed prepaid architectures/methods determine if a subscriber has sufficient account balance to deliver a short message, prior to message delivery. A message may be prevented from being delivered (at the source end or destination end) if a subscriber account has insufficient funds. A prepaid tariff engine supports remote interaction with the SMSC and web chat servers to apply real-time billing for each message. A service provider may define subscriber rates and/or tariffing plans to apply real-time billing for sending/receiving messages. Message billing may be based upon, e.g., rate per message, message count, character count, Time of Day, Day of Week, message type, and/or mobile location. The prepaid short messaging service preferably supports internet access to subscriber's account balances and status maintained in the prepaid short messaging database of the prepaid messaging server.
