A Mobile Station (MS) is able to vertically roam in either direction between two different nerworks, i.e, WWAN and WLAN. The MS is equipped with a dual mode Radio for WWAN and WLAN transmissions. The WLAN Radio is linked to a WLAN Enterprise Gateway Controller (EGC) via a first air link and the WWAN Radio is linked to a WWAN Base Transceiver Station (BTS) via a second air link. An outgoing VoIP call from the WLAN Radio to a remote party on the WWAN will transition or seamlessly switch over to a WWAN connection when the MS detects packet error rates, frequent scale back or consistent signal degradation.

A location system is disclosed for wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location systems for outputting requested locations of hand sets or mobile stations (MS) based on, e.g., AMPS, NAMPS, CDMA or TDMA communication standards, for processing both local mobile station location requests and more global mobile station location requests via, e.g., Internet communication between a distributed network of location systems. The system uses a plurality of mobile station locating technologies including those based on: (1) two-way TOA and TDOA; (2) home base stations and (3) distributed antenna provisioning. Further, the system can be modularly configured for use in location signaling environments ranging from urban, dense urban, suburban, rural, mountain to low traffic or isolated roadways. The system is useful for 911 emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.

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; and (4) 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 signaling 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.

A method, security system control module and policy server for providing security for Mobile Stations (MSs) in a Packet-Switched Telecommunications System. When an MS accesses the system, its identity is sent to a security system control module that retrieves a security profile associated with the MS. A policy server of the security system control module stores individual security profiles, default security profiles and group security profiles for registered subscribers. Security settings associated with the MS security profile are returned from the policy server to a mobile security manager of the control module, which then determines if they should be propagated in the system. When no previous network access was made in a given time period by an MS having similar security settings, i.e. belongs to the same group security profile, the settings are propagated in the system in order to be enforced, for providing security protection for the MS.

A method for automating changes to a service plan between a mobile subscriber and a wireless service provider is provided. In one embodiment, the method creates a temporary service plan for the subscriber. This method includes: a) receiving a request to create the temporary plan, b) retrieving the subscriber's existing service plan from a subscriber database, c) providing a change selection menu to the user, d) modifying the existing service plan in conjunction with one or more user selections associated with the change selection menu to create the temporary plan, and e) storing the temporary plan in the subscriber database. In another embodiment, the method modifies the subscriber's existing service plan and the modified service plan supercedes the previous service plan. In another aspect, a method for processing a call from a mobile station associated with the subscriber when the temporary service plan is in effect is provided.
