A location system is disclosed for commercial wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location centers for outputting requested locations of commercially available handsets or mobile stations (MS) based on, e.g., CDMA, AMPS, NAMPS or TDMA communication standards, for processing both local MS location requests and more global MS location requests via, e.g., Internet communication between a distributed network of location centers. The system uses a plurality of MS locating technologies including those based on: (1) two-way TOA and TDOA; (2) pattern recognition; (3) distributed antenna provisioning; (5) GPS signals, (6) angle of arrival, (7) super resolution enhancements, and (8) supplemental information from various types of very low cost non-infrastructure base stations for communicating via a typical commercial wireless base station infrastructure or a public telephone switching network. Accordingly, the traditional MS location difficulties, such as multipath, poor location accuracy and poor coverage are alleviated via such technologies in combination with strategies for: (a) automatically adapting and calibrating system performance according to environmental and geographical changes; (b) automatically capturing location signal data for continual enhancement of a self-maintaining historical data base retaining predictive location signal data; (c) evaluating MS locations according to both heuristics and constraints related to, e.g., terrain, MS velocity and MS path extrapolation from tracking and (d) adjusting likely MS locations adaptively and statistically so that the system becomes progressively more comprehensive and accurate. Further, the system can be modularly configured for use in location signing environments ranging from urban, dense urban, suburban, rural, mountain to low traffic or isolated roadways. Accordingly, the system is useful for 911 emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.

PCT No. PCT / SE96 / 00210 Sec. 371 Date Aug. 15, 1997 Sec. 102(e) Date Aug. 15, 1997 PCT Filed Feb. 16, 1996 PCT Pub. No. WO96 / 25830 PCT Pub. Date Aug. 22, 1996The position of a mobile station in a cellular mobile telephone system, particularly a GSM system, is determined by carrying out a simulated call setup, i.e., the call setup is interrupted subsequent to a telephone switching center (MSC) having received a paging response containing the identity of the cell and, optionally, a timing advance. The simulated call setup is initiated by generating a modified short message signal (SMS) which is not registered in the SMS catalogue of the mobile station and which is not shown to the user of the mobile station. The SMS commands the mobile station to carry out a position determining sequence in order to establish parameters for use in establishing the position of the mobile station, for example by commanding the mobile station to connect itself to a base station contained in its neighbor list, analyze the geographical position of the base station, and subsequently send the position determining parameters to a position handler. The geographical position of the base station is analyzed from the cell identity and, if available, the timing advance, the position of the mobile station being presented graphically on a picture screen and constantly updated after each call setup. The call setups are generated by the position handler.

A command, such as an application specific command, is communicated from a central host to a remote station via a cellular mobile radio network. The station may be a fixed or roaming device. The central host sends the command a network switch, such as an SS7 SSP, wherein the command comprises a mobile identification number (MIN) and an electronic serial number (ESN). The network switch queries an associated HLR database to locate the remote station, the query specifying the MIN and the ESN. If the HLR does not recognize the MIN / ESN combination, it so informs the network switch, as well as the VLR associated with the MSC serving a remote station identified by the ESN. In response to the notification from the HLR, the VLR removes any entry in its database relating to the ESN and updates its database with the new MIN / ESN combination transmitted by the HLR to the VLR. The VLR confirms with the HLR that it has taken these steps and then sends the command to the remote station by calling the station using the new MIN / ESN.

A method and system for communicating information includes evaluation regarding routing of calls performed at a call control point in an ITSP and / or wireless network. A PIC identity associated with another party's preferences is acquired and sent to the call control point. The PIC identity identifies the type of the carrier network (e.g., circuit switched or VoIP) and is used to make further routing decisions. If a circuit-switched carrier is identified, the IP homing leg is terminated at the voice gateway in the recipient's HPLMN and information is sent over to the GMSC where normal, circuit-switched routing procedures. If a VoIP carrier is identified then the called user's roaming number is retrieved from the HLR, and the call is further routed directly over the IP domain towards a voice gateway at the visited network minimizing the number of transcodings. Additional transcoding steps can be avoided if a single encoding is agreed upon according to “tandem free operation” (TFO). Combining inband signaling through the telephony exchanges and out-of-band signaling in the IP network it is possible to achieve, for a mobile subscriber, one encoding and one decoding of a voice.

A subscriber to a universal point of contact service designates a preferred point of contact at which a communication initiator, such as a telephone caller, can contact the subscriber. Such an initiator desiring to contact the subscriber uses the subscriber's email address to establish a communication session with a device associated with the subscriber's preferred point of contact. The subscriber's email address is input to an initiating device, preferably a telephone or facsimile machine, using an entry device capable of entering an email address. A requestor unit, receiving the email address, locates a repository of the subscriber's point of contact information, and requests that information. The repository sends the point of contact information the subscriber has designated as preferred, and the requester unit uses that information to control a telephone switch to establish a communication session between the initiating device and the subscriber's preferred point of contact device.

A method and system (100) establishes voice communications between a computer operator (102) and an agent (104) of a business over a computer network, such as the Internet (108). Using an operator computer (106), the computer operator (102) views advertisements of the business' products or services on the Internet (108) via customized home pages (200). When the operator (102) wishes to order a product or ask additional questions about a product, the operator (102) activates a “call me” button (210). A return call screen (300) is then presented to the operator (102) with areas to insert a name (302), a telephone number (304) and a time to call (306). This information is packetized in a call request which is transmitted over the Internet (108) to a telephone switching system (112) associated with the business. The telephone switching system (112) subsequently dials the telephone number (304) at the time to call (306). When the operator (102) answers an operator telephone (120), the telephone switching system (112) connects the operator (102) with the agent (104) via an agent telephone (118). The telephone switching system (112) may be comprised of a telephone computer (114) and an automatic call distributor (116).

A method and system for transferring telephone calls and data between computer programs in a call center. Flow connection modules associated with call center application programs allow data and telephone calls to be transferred from one computer program to another in the call center. The flow connection modules may be combined with a locator program such that the combination replaces the automatic call distributor (“ACD”) in a call center. The flow connection modules enable development of modular call centers, allowing call center agent workstations to be easily increased or decreased. In operation, an application notifies its flow connection module that a call on a telephone in the workstation should be transferred to another application. The flow connection module establishes a data connection with a flow connection module associated with the other application. The flow connection module sends call-related data to the other flow connection module which then returns the telephone extension associated with the other application. The flow connection module requests a computer telephony interface (“CTI”) link associated with a phone switch to transfer the call to the other application's telephone. The CTI link directs the phone switch to transfer the telephone call from the original application's workstation to the telephone of the other workstation. Having received notification of the transferred call, the other flow connection module informs the original flow connection module that the call has been successfully transferred, and the original flow connection module then disconnects the data connection.

In a CDMA wireless communication system (200) a dispatch call can be established between two CDMA mobile stations (202, 226), or between other mobile stations and the CDMA mobile station, or between a CDMA mobile station and a computer (236) located outside of the wireless system. To reduce the delay normally association with call set up in a CDMA system, a dispatch processing network (128, 144) is provided in addition to a telephony switch (118). Dispatch calls and call set up requests are routed to the dispatch processing network from the radio access network (110) which includes base stations (204, 206). Once a dispatch call request is made, while the dispatch processing network begins setting up a traffic channel for the originating mobile communication device, the target is also paged, and upon responding, set up on a traffic channel. The concurrence of establishing radio links with the target and originating communication devices substantially reduces dispatch call set up time.

A system for presenting a recorded message on behalf of an agent receiving a call at an agent station in a call center, the agent station having a telephony interface for receiving calls and a personal computer with a video display unit (PC / VDU), has a telephony switching apparatus enhanced by a computer-telephony integration (CTI) processor, an Interactive Voice Response (IVR) system executing a voice treatment option (VTO) software, coupled to the telephony switching apparatus and the CTI processor; and a data repository having recorded messages stored on behalf of the agent and accessible to the CTI processor. The CTI processor routes incoming calls to the telephony interface for the agent, uses data associated with the calls for selecting appropriate recorded messages, and causes, by controlling the IVR, a retrieved recorded message to be played to a caller upon the agent picking up the routed call. The system is useful with both conventional telephone systems and data network telephony, such as over the Internet.

Systems and techniques for routing and transmission of short message service messages are described. A user profile associated with a wireless telephone includes conditions relating to a user's need or desire to receive a text message through a device other than the wireless telephone and the user's preferences in the event of each of the conditions. The conditions include whether a user's instant messaging client is active. If the client is active, the user profile include the address of the client. When a text message arrives for the user at a wireless telephone switching center, the switching center determines if the message is to be sent to the user through the wireless telephone network, through the internet messaging client or both. Depending on the desired routing of the message, the message is transmitted through the wireless network or formatted and sent as an instant messaging message, or both.

A client-server telephone call router system as part of a customer premises system has a client-server router adapted to execute on a telephony switch, such as a public branch exchange (PBX) or other telephony switch, or on a processor connected by CTI link to a telephony switch. The telephony switch or processor executing the router is connected to a local area network (LAN) that also interconnects computer workstations proximate to telephones connected to the telephony switch. Client user interface applications run on the computer workstations, allowing clients to edit routing rules for the router, which has a list of routing rules keyed to users and workstations of the customer premises system. The editing rules are kept by the router in portions dedicated to individual users. With this system a user can edit at a workstation on the LAN his\her own routing rules, and transmit the edits to the client-server router where the rules will be followed to route calls for that user and protocol.

A method and system for creating a virtual roaming solution for a MSISDN using a softphone over an IP network. The system involves (i) implementation of a novel virtual mobile network (VMN) comprising virtual visitor location register (vVLR), virtual home location register (vHLR) and virtual multiple switching centre (vMSC) on an IP server responsible for managing IP call traffic administration, and (ii) implementation of a novel mobile to internet gateway (MIG) comprising an VoIP gateway for diverting call traffic from the mobile network to the IP network, and an IP server with vMSC functionality to translate routing information from the VMN to GSM network so as to appear to the GSM network as a traditional mobile operator. The system dynamically registers the subscriber to the IP network, and provides valid routing information to the MSC (Mobile Switching Centre) or public telephone switch to route the call over to the NGN (next generation network) operator in the IP space.

Methods, systems, and articles of manufacture enable routing a communication from a cell phone associated with a service provider in which the cell phone is located in a predetermined area in which the service provider does not have an operational base station or in which routing assistance is required. A cell base station having one or more antennas is provided in an aircraft. Each of the antennas is configured to monitor a respective sector of the predetermined area for a cell phone communication when the aircraft is flown in proximity to the predetermined area. A registration request from a first cell phone in the predetermined is detected via the cell base station and an ID and location associated with the first cell phone is routed to a ground based telephone switching office, such as the mobile telephone switching office associated with the service provider of the detected cell phone.

The present invention provides a service node capable of coordinating call processing for incoming calls intended for any one of multiple telephony devices of a given entity, such as a business or individual user. Switching devices, such as traditional telephony switches or internetworked gateways controlling call routing, are configured to interact with the service node to determine how to handle incoming calls to the telephony devices that they serve. Through a variety of techniques, the entity can dynamically instruct the service node how to route incoming calls, and preferably, upon putting those instructions into effect, the service node will send an alert to the entity. The instructions are used by the service node to create call processing rules for the switching devices to apply to an incoming call intended for any of the entity's telephony devices.
