Abstract: Systems and methods to determine the location information of an emergency call made from a radiotelephone. The system employs multiple radio direction finding (RDF) devices, which is capable of determining the angle of arrival of a radio signal. The MSC sends a request along with radio information to a location processor, which controls RDF devices. The location processor sets up each RDF device to track the radio signal. If at least two RDF devices are successful in tracking the radio signals and returning information about the radio signal, then the location processor can determine the location of the radiotelephone by using a triangulation method.

Abstract: A radiophone, arranged to assume a plurality of states, that includes a user interface provided with a display, a keypad, and control means. The keypad is arranged to enter the plurality of states, which changes the plurality of states. The keypad includes a first group of keys and a second group of keys that includes two soft keys with multiple functionality for handling access to a menu structure, and a scroll key to scroll between a group of items in a menu of said menu structure. The control means is arranged to control the display of an action, from said group of actions, as a default function, and to detect a state change event, which will change the state of the radiophone and redefine the functionality of the two soft keys in response to the preceding state and the nature of the detected state change event.

Abstract: A mobile telephone system providing general packet radio service (GPRS) includes a radio network controller (RNC) (2A) and/or a base station controller (BSC) and an associated serving GPRS support node (10A) for each domain. The RNCs (2A) and the SGSNs (10A) are interconnected by an Internet protocol (IP) network. When a mobile telephone (6A) moves from one domain to another, the RNC, in the new domain, takes over handling the mobile telephone. The current SGSN (10A) has a detector (20) which detects whether the existing transmission is a real-time transmission and, if it is, a diverter (22) comes into operation to couple the RNC in the new domain to the current SGSN (10A) rather than its associated SGSN (10A). When the call ends, the current SGSN (10A) hands-over the call to the SGSN (10A) in the new domain. This procedure ensures minimal interruption to real-time services by keeping the call anchored to the current SGSN (10A).

Abstract: A mobility support element (MSC/VLR; SGSN, GGSN) for a cellular radio network supporting circuit-switched and packet-switched connections to/from a mobile station (MS). For each mobile station (MS), there is a set (LSA1, LSA2) of special cells (C1-C3, C9, C10) providing special service. A radio control element (BSC1, BSC2) determines whether the mobile station (MS) is in a special cell. Charging elements (CG, BC) receive charging information comprising detail items which indicate events which affect charging. The mobility support element (MSC/VLR; SGSN, GGSN) receives, when it begins to serve the mobile station, a list (LSA1, LSA2) of the special cells for the mobile station, and sends the list to the serving radio control element (BSC1, BSC2). The mobility support element also supports or performs classification of the detail items into two classes depending on whether or not the corresponding event occurred while the mobile station was in a special cell.

Abstract: A method and system for monitoring wireless network conditions. Two mobile stations are coupled with a computer. The first mobile station interacts with the network and thereby establishes diagnostic data concerning network conditions. The first mobile station then reports that diagnostic data to the computer. As the computer receives the diagnostic data from the first mobile station, the computer obtains location data indicative of the current location of the first mobile station. The computer then provides the diagnostic data and corresponding location data to the second mobile station, which in turn transmits the data to a remote entity via the wireless communications network. As the remote entity receives the data, the remote entity may generate output reports and alerts as desired.

Abstract: A connection is supported in a radio access network (RAN) between an external network to a UE using a first RAN node and second RAN node. The transmission rate from the first RAN node to the second RAN node is regulated based on a rate control request from the second RAN node. In one example embodiment, the first and second RAN nodes correspond to a serving radio network controller and a drift radio network controller, respectively. In another example embodiment, the first and second RAN nodes correspond to a radio network controller and radio base station, respectively. The rate control request is made based upon a congestion or load condition being monitored by the second RAN node. When the load condition is detected, the second RAN node requests the first RAN node to lower the transmission rate of information. Conversely, when the load condition is relieved, the second RAN node can request that the first RAN node increase the transmission rate of information.

Abstract: An apparatus, method, and article of manufacture that provides an efficient way to invoice the users of a communication system (100) for the system resources consumed. Invoicing is based upon flexible criteria that can be adapted depending upon the charges a resource provider charges. For example, a user may incur a one-time charge for downloading a desired application program, or the user may be charged a download fee plus a recurring monthly fee for having continual access to the program and any updates to the program. A fee might also be charged for each time the application is used. These fees are recorded as debits and transferred to an invoicing location where an invoice reflecting the debits is constructed. For example, the debits may comprise fees for wireless service access, Internet service access, downloaded application programs, data, multimedia services, or other fees.
