The present invention retunes adjustable base station antennas of a wireless communications system in order to improve performance metrics that are determined by measurements and that are associated with sub-sectors within the wireless communications system. The present invention calculates and applies control signals to the adjustable antennas to improve the performance in accordance with the performance metrics. Thus, the present invention obviates much of the labor that is required for retuning the wireless communications system with changing radio conditions.

Apparatus and method for measuring and controlling the performance or an adjustable antenna on a sub-sector basis

The present invention bills a call in accordance with a measured quality of service (QoS) level afforded by the call and specified in a service level agreement. The measured quality of service is determined from a collection of measurements associated with the call. An adjustment factor is determined by a subscriber class of service and the measured quality of service. The adjustment factor is utilized by a billing processor in rating the call.

Method and apparatus for policy-based charging for telecommunications services

The present invention provides a method and Mobile Switching Center (MSC) for re-establishing a call in a communication system. The MSC receives from a network element a callback request to re-establish a call, such as an emergency call, between the network element and a mobile unit. The callback request includes a callback number. The MSC determines whether the callback number can be used to alert the mobile unit. If the callback number cannot be used to alert the mobile unit, the MSC determines an identification number of the mobile unit. The MSC then alerts the mobile unit by utilizing the identification number of the mobile unit and re-establishes the call on the original call path between the mobile unit and the network element.

Method and apparatus for re-establishing a call in a communication system

A wireless communications system provides call transfer capability for an incoming call to a mobile subscriber unit. The mobile subscriber unit requests the call transfer to a serving MSC. The serving MSC relays the request to a home location register, and the home location register executes the request by initiating the call transfer in conjunction with an originating MSC. This arrangement obviates the need for supporting call transfer on the serving MSC and the need for inter-MSC facilities once the call transfer is completed. Moreover, the approach of the present invention enables call transfer to be ubiquitously supported within a wireless communications system.

Apparatus and method providing ubiquitous call transfer of an incoming call to a mobile subscriber unit

An apparatus and method in a telephone communications system that provide for redirecting a call by an adjunct processor, utilizing a control message. The control message contains various directives for current or subsequent execution by a telephone switching center, which can assume a function of a mobile switching center in a wireless communications system or a landline switching center in a landline telephone system. Directives in the control message instruct the telephone switching center to redirect a call contingent upon subsequent call events that can occur.

Method and apparatus providing call redirection for subsequent call events in a telephone communications system

Techniques for providing enhanced wireless services such as interactive voice services to a serving mobile switching center which is originating a call for a mobile station that requires such services via the public switched telephone network (PSTN). The serving mobile switching center has a trigger which causes it to respond to a call from the mobile station by sending a message according to the IS 41 protocols to the enhanced mobile switching center that provides the enhanced service. The enhanced mobile switching center responds to the message by associating the contents of the message with a temporary local dialing number (TLDN) and sending a message to the serving mobile switching center that contains the TLDN. The serving mobile switching center uses the TLDN to set up a call via the PSTN to the enhanced mobile switching center, which then uses the content of the message associated with the TLDN to establish which enhanced service is required. It calls the service node for the enhanced service and bridges the call from the serving mobile switching center to the service node. The call provides a voice channel for the enhanced service.

Methods and apparatus for accessing enhanced wireless services platforms via the public switched telephone network

A method for providing universal access to service features by subscribers of a wireless telecommunications service provider comprises establishing a gateway switch interconnected to a plurality of mobile switching centers maintained by other wireless service providers. Trunk connections and signaling links between each mobile switching center and the gateway switch allow the gateway switch to establish call connections and apply service features. Advantageously, the gateway switch is responsible for applying service features and establishing call connection for its subscribers and thereby, results in predictable access to wireless telecommunications services.
