The present system for identifying the location of selected mobile stations includes two components: a first component that authenticates an authorized party who logs into the Mobile Switching Center, and a second component that is responsive to the entry of a system activation command by the authorized party for locating selected mobile stations and providing mobile station location information to the authorized party. The present system for identifying the location of selected mobile stations enables a service provider to track a mobile station through the use of Autonomous Registrations or the polling of a selected mobile station or a set of mobile stations. Once communication with the selected mobile station is established, the GPS coordinates of the selected mobile station are retrieved and provided to an authorized party to enable them to locate the subscriber and their mobile station.

In order to reduce the traffic on the paging channel, the system for reducing paging channel occupancy for message waiting indication in mobile switching centers allows the Message Waiting Notification process to determine a last zone in which the Mobile Subscriber was located and only transmit the Message Waiting Indication to the cells within that zone. This eliminates message transmission on the paging channel of cells which are not likely to have the Mobile Subscriber Station residing in their service area. Multiple retries can be attempted and if the last retry is being activated, the paging can be extended to cover all zones in the Mobile Switching Center. The sharing of information about when a mobile has responded to a message waiting count between the Serving MSC and the Home MSC also reduces the paging channel occupancy. The method of not sending a message waiting notification when a mobile has already acknowledged the message count greatly reduces the impact of Message Waiting Notification on the paging channel occupancy. In particular, border cell areas where the Mobile Subscriber Station can bounce between MSCs is where the biggest benefit can be derived.

System for reducing paging channel occupancy for message waiting indication in mobile switching centers

The message waiting notification update system is operable in the serving Mobile Switching Center and, upon receipt of a message-waiting acknowledgement from the mobile subscriber station, updates the local copy of the subscriber's data in the Visited Location Register and forwards this information to the subscriber's Home Location Register. The Home Location Register stores this received data for use when the next successive Registration Notification is received from a new serving Mobile Switching Center or in response to the subscriber initiating a local access. When the serving Mobile Switching Center receives a Registration Notification message return result from the subscriber's Home Location Register and the message waiting notification count is the same as the count previously sent to the Home Location Register, the serving Mobile Switching Center does not have to transmit a message waiting notification over the forward control channel to the mobile subscriber station.

Systems for providing message waiting notification updates in a cellular communication network

There is therefore a need to forward the message waiting indication data to Mobile Switching Centers whose service areas overlap with the service area of the Mobile Switching Center presently serving this mobile subscriber's wireless communication device. In this manner, any one of these Mobile Switching Centers can update the mobile subscriber with regard to message waiting indications. This is accomplished by the use of the ISPAGE message which is used to forward the message waiting indication data to Mobile Switching Centers whose service areas overlap with the service area of the Mobile Switching Center presently serving this mobile subscriber's wireless communication device.

An apparatus, method and system are disclosed for providing a default mode for authentication failures in a mobile telecommunication network. The system includes an authentication center (typically co-located within a home location register), an adjunct network entity, and an originating mobile switching center. The home location register generally stores information pertaining to a mobile unit, such as a cellular or PCS mobile telephone. The adjunct network entity contains one or more application nodes, such as an announcement application node for providing an announcement on a call leg to the mobile unit. When the network has been accessed by a mobile unit through a call leg, the originating mobile switching center is configured to perform an authentication procedure. The originating mobile switching center further is configured, when the authentication procedure has resulted in an authentication failure, to receive a message from the authentication center to deny the mobile unit access to the network, to terminate a communication session with the mobile unit, and to route the call leg to the announcement application node for the provision of an announcement on the call leg to the mobile unit. Following such an announcement, the originating switching center is also configured to route the call leg to a customer service center, for example, to reprogram the mobile unit.

Apparatus, method and system for providing a default mode for authentication failures in mobile telecommunication networks

An apparatus, method and system are provided for message-based intelligent tandeming of an incoming call to an application node in telecommunication systems. The various embodiments utilize a new parameter, referred to as a tandem parameter, to designate whether incoming calls to a particular subscriber are to be tandemed to an application node or are to be delivered directly to the subscriber. The preferred system embodiment includes an adjunct network entity, a database, and a switching center. The adjunct network entity, such as a service circuit node or service control point, has one or more application nodes or platforms, supporting various telecommunication services such as prepaid services, calling party pays services, and one number services. The database, such as a home location register or visitor location register, stores information such as subscriber profiles, and includes storing the tandem parameter. The switching center, such as a mobile switching center, is configured to receive an incoming call leg directed to a called party directory number, to transmit a first message to the database to determine call treatment instructions, and to receive from the database a second message containing a tandem parameter. When the tandem parameter does not indicate tandeming, the incoming call leg is routed to the called party directory number, and when the tandem parameter does indicate tandeming, the switching center obtains a routing parameter and performs digit analysis of the called party directory number. The switching center, when the digit analysis has been performed successfully, tandems the incoming call leg to the application node, and when the digit analysis has not been performed successfully, provides an individually configured default mode for the incoming call leg.

Methods for locating a missing called mobile unit in a telecommunications network are disclosed. With various equipment manufacturers present in the telecommunications industry, methods for use with a variety of equipment made by those manufacturers are necessary. The equipment in the network would include mobile units, home location registers and mobile switching centers. Through alterations in the operation of the home location registers and/or the mobile switching centers, the responses to page requests and/or routing requests are varied from the typical responses. Through those variations, missing called mobile units may be located in an efficient manner, regardless of the equipment provider.

Method for flood paging in a telecommunications network

A mobile switching center (MSC) in accordance with the principles of the present invention provides access to a subscribers voice message center from the subscriber's roaming mobile station. The MSC is responsive to a &ldquo;RemoteFeatureRequest&rdquo; Invocation by the roaming mobile station in which the subscriber's directory number is the same as the dialed digits by routing the call from the mobile station to the subscriber's voice message center. The MSC may also be responsive to a &ldquo;OriginationRequest&rdquo; employing the subscriber's directory number as the dialed digits by routing the roaming mobile station's call to the subscriber's voice message center. If the MSC supports both RemoteFeatureRequest-, and OriginationRequest-based access to the subscriber's voice message center, the MSC determines which of the approaches to use in response to the reception of a subscriber's directory number as the dialed digits from the subscriber's roaming mobile station. The MSC may make this determination on the basis of information stored in a local database that indicates the method employed by other telecommunications devices, such as other MSCs, Visiting Location Registers (VLR), or Home Location Registers (HLR), within the system. One of the methods, that is, the use of an Origination Invocation or the use of a RemoteFeatureRequest invocation, may be chosen as a default method.

Alternative message usage for voice mail retreival via revertive calling

The invention provides systems, including a methods and apparatus, for providing seamless telephone service across MSC's that support multiple or different protocols. In accordance with a preferred embodiment of the invention, the home mobile switching center, where the subscriber record is stored, is equipped to respond to a first inquiry signal from an originating mobile switching center by identifying itself to the originating mobile switching center. The incoming call may then be trunked to the home mobile switching center and forwarded to the visited mobile switching center according to the second protocol. According to another preferred embodiment, in response to the first inquiry signal, the home mobile switching center sends a second inquiry signal to the visited mobile switching center. The first inquiry signal represents a request for an identification number identifying, in the first protocol, the visited mobile switching center. The second inquiry signal represents a request for an identification number identifying in the second protocol, visited mobile switching center. In response to the second inquiry signal, the visited mobile switching center returns a first response signal to the home mobile switching center. In response to the first response signal, the home mobile switching center sends a second response signal to the originating mobile switching center, the second response signal representing, in the first protocol, a number identifying the visited mobile switching center. The call is then directly routed from the originating mobile switching center to the visited mobile switching center.
