Abstract: An architecture to support service features for wireless calls in a wireless telecommunication system is disclosed. Service feature administration for a wireless terminal is provided by a packet data feature server in a home network that is connected to a packet data network. During call setup on behalf of the wireless terminal, the feature server is accessed via the packet data network to manage service features that are specific to the wireless terminal.

Abstract: Apparatus and a method for establishing a cellular mobile call. If no radio traffic (voice or data) channels are available for a calling Mobile Station (MS), then a test is made to determine the expected wait time before a channel becomes available. If the expected wait time is less than a first threshold, then the call request is queued. If a channel does not become available before a second time threshold, then the caller is notified that the call has been queued and is expected to be established in a short time. A control message is sent to the MS to trigger an indication of the queued status to the user. The indication may be one or more tones, a data display, or the playing of a pre-recorded announcement. If the expected wait time is more than the first threshold, the caller is given the opportunity to be called back when a radio channel becomes available. Advantageously, the number of failed calls because of unavailable traffic channels is reduced, and the caller's annoyance level is reduced.

Abstract: The method provides for a first network controller, operating according to a first radio technology, to form and send a relay message to a second network controller, operating according to a different, second radio technology. The relay message includes an embedded message for the second network controller. The embedded message may be a transition message requesting transition of a packet switched call for a mobile station handled by the first network controller to a call for the mobile station handled by the second network controller. The method further provides selection of another wireless element for service at a wireless unit, using a current wireless element. A wireless unit receives a message identifying at least one other wireless element, available to the wireless unit and to which a wireless element currently in communication with the wireless unit is also in communication with and the wireless unit selects another wireless element for possible future service based on the message.

Abstract: The present interoperability system serves to pass presence and supervision information relating to a user's wireless station set between a cellular communication network and an enterprise communication network. The interoperability system functions to extend the services, such as call pick up, provided in the enterprise communication network to the cellular communication network based on the presence and supervision data provided by the interoperability system. The provision of ubiquitous call pick up service is accomplished by transmitting alert signals not only to the user's telephone line in the enterprise communication network to alert members of the call pick up group proximate to the user's office, but also to the user's wireless station set operating in the service area of the cellular communication network as well as members of the call pick up group also operating in the service area of the cellular communication network.

Abstract: The present interoperability system serves to pass presence and supervision information relating to a user's wireless station set between a cellular communication network and an enterprise communication network, which typically includes a Private Branch Exchange system. The interoperability system functions to extend the wireless Private Branch Exchange services provided in the enterprise communication network to the cellular communication network based on the presence and supervision data provided by the interoperability system. The provision of ubiquitous service to the user, regardless of their location provides a significant advantage over existing Private Branch Exchange and cellular communication network services. In addition, the user is equipped with only one wireless station set, which can operate as a cordless Private Branch Exchange extension in the office or as a standard wireless station set outside of the office.

Abstract: Systems and techniques for providing calling information and features to a wireless telephone are described. A server hosting directory information and commands used to implement calling features establishes a packet data connection to a wireless device. The wireless device uses the packet data connection to locate and retrieve desired calling information and commands. The calling information is used by the wireless device initiate a voice connection to a telephone identified by the calling information. The commands are executed by the wireless device in order to implement calling features provided by the system in which the wireless device is used.

Abstract: The apparatus and method are fast network SIP/SDP (Session Initiation Protocol/Session Description Protocol) procedures for conference operations upon request from end user with optimization of network resources. The apparatus has an SIP/SDP based network controller that, upon a received request, joins first and second calls into a conference call with at least a third call. The SIP/SDP based network controller is structured to negotiate, allocate and re-configure network resources.

Abstract: Apparatus and a method for establishing a cellular mobile call. If no radio traffic (voice or data) channels are available for a calling or called mobile station (MS), then a test is made to determine the expected wait time before a channel becomes available. If the expected wait time is less than a first threshold, then the call or the call request is queued. If a channel for an incoming call to an MS does not become available before a second time threshold, then the caller is notified by an announcement that the call has been queued and is expected to be established in a short time. If the caller of an incoming call to the MS does not disconnect, then the MSC waits for an available channel and establishes a connection to the MS over that available channel. For an outgoing call from an MS, a control message is sent to the MS to trigger an indication of the queued status to the user. The indication may be one or more tones, a data display, or the playing of a pre-recorded announcement.

Abstract: The distributed cellular communication system architecture for the co-existence of multiple technologies uses the mapping table capability of the Asynchronous Transfer Mode network and the multi-layer nature of the signaling protocol that is used in cellular communication networks to transparently interconnect cellular communication network elements that use different technologies and/or signaling protocols. The present distributed cellular communication system architecture avoids the need for significant changes in the cellular call processing software to accommodate new cellular communication network components by inserting signal routing data into the Asynchronous Transfer Mode network routing tables to thereby interconnect signals between compatible endpoints that are connected to the Asynchronous Transfer Mode network.

Abstract: A method and apparatus for establishing a wireless telephone connection when a call cannot be made immediately. The caller and the wireless system negotiate for a later time when another attempt will be made to establish the call. Shortly before that time arrives, the wireless system reserves a radio channel and retains that channel for the deferred call. Then, the system calls the customer back, or waits for the customer to attempt the call. A reserved channel is then used for the call if the system has been successful in reserving such a channel. Advantageously, there is a high probability that the deferred call will have a radio channel available.

Abstract: A method and apparatus for permitting a wireless telecommunications caller to use an alternate service provider if the primary service provider has no available bearer channels. If the primary service provider has no available bearer channels for a call, that service provider sends a message to the caller's mobile station to switch its control channel to one of the control channels of an alternate service provider. The caller then attempts to complete the call over the facilities of the alternate service provider. Advantageously, spare facilities of the alternate service provider can be employed to good use; advantageously, the caller's service is improved because the call is not finally blocked when no bearer channels are available for the call.

Abstract: The cellular call processor having concurrent instances of call models supports mixed media communication connections. The cellular call processor processes each of the media components of the mixed media communication connection in an independent, yet coordinated manner. Thus, each of the media components of the mixed media communication connection can be processed in an efficient media-specific manner and even directed to different destinations. The cellular call processor can implement this capability in a plurality of ways, one of which is to maintain the existing voice call model and create a new call model for each of the other call components in a media-specific manner. Alternatively, multiple instances of the same call model can be used, with each call component being served by a separate instance of the call processing code.

Abstract: A telecommunication system routs real-time information traffic from an originating digital radio unit served by an originating network to a terminating unit served by a terminating network via an intermediate network interconnecting the originating and terminating networks. The originating digital radio unit has an encoder/decoder (e.g., a vocoder) for generating digital wireless frames from information that is input thereto. The originating network includes an originating node with an encoder/decoder for performing wireless-specific conversion of the digital wireless frames to digital wireline (e.g., PCM) traffic. The intermediate network includes an originating-end interface node with an encoder/decoder for compressing the digital wireline traffic for transport across the intermediate network.

Abstract: In a cellular mobile telecommunications system, apparatus and a method for altering the charge for a call if the occupancy of radio channels is above or below an appropriate threshold. For one proposed service, the users are charged less if they make calls during the time when the occupancy of radio channels is less than a threshold. For users having another proposed service, the charge is greater when the occupancy of the radio channels is above another threshold. Advantageously, users are encouraged to use the mobile telecommunications service when the occupancy of regular channels is low, and to use the service less when the occupancy of the radio channels is high.

Abstract: A wireless terminal is disclosed that is capable of establishing a communications channel with either a public wireless network or a private wireless network on existing IS-95 CDMA facilities without changing the air interface or requiring the existence of independent private network facilities. Furthermore, a wireless terminal is disclosed that enables a user of a wireless terminal to affect which private wireless network the wireless terminal accesses, again on existing IS-95 facilities and without changing the air interface. The wireless terminal comprises two or more lists of SID/NID signals: a default list and at least one override list. Both the default list and the override list provide a different preference for which public or private network the wireless terminal accesses when a call is placed from the wireless terminal. A switch in the wireless terminal advantageously causes the wireless terminal to use either the default list of SID/NID signals or one of the override lists of SID/NID signals.

Abstract: A telecommunication system routes wireless-specific digital frames from a first wireless communication device across a data-oriented network, without vocoding, for information delivery to a second communication device while implementing multi-party conferencing and tone/announcement generating functionality. Tone and announcement generation services are provided while the call path retains the wireless-specific digital frame format between the first wireless communication device and the terminating gateway. When tones are generated by the first wireless communication device, signaling messages are sent directly to the terminating gateway vocoder to initiate the generation of full rate DTMF tones at the terminating network. When tones and announcements are sent to the first wireless communication device, a resource server, working together with a feature server, generates a wireless-encoded version of the tone or announcement.

Abstract: A system includes a first virtual end point processor (332) operably coupled to a plurality of channel elements (304) and a second virtual end point processor (340) operably coupled to a plurality of frame selectors (314). The system also includes at least one signaling manager (318, 334) that is arranged and constructed to establish a communication path that terminates at the first virtual end point processor (332) and the second virtual end point processor (340) prior to receiving a request for resources for a data call, such that set-up time for the data call through a wireless network is reduced.
