Abstract: Embodiments are provided for registering an electronic device of a subscriber for cellular-based communications. According to certain aspects, the cellular-based communications may be facilitated by a data center while the electronic device is not easily within range of a cellular network, such as when the electronic device is traveling on an aircraft. The registration includes associating a subscription identification of a cellular services plan with an identification of the electronic device, from which a registration server may create an account associated with the cellular-based communications. Further, the registration server may generate a digital certificate using the electronic device identification and issue the digital certificate to the electronic device.

Abstract: A method in one application of maintaining a paging status associated with a communication device. The method also comprises paging the communication device based on the paging status. A system in one application comprising a communications controller configured to store a paging status that is associated with a communication device. The system further comprising a communications manager communicatively coupled to the communications controller. Also, at least one data store is communicatively coupled to the communications controller. The communications controller pages a communication device based on a paging status. The paging status is stored in one of the at least one data store.

Abstract: A method is provided for paging a mobile station (40) served by a wireless telecommunications network (A). The method includes: remembering a last known location of the mobile station (40), and implementing a first paging strategy for the mobile station (40) within a first collection of cells (32) served by a first mobile switching center (20).

Abstract: Methods and systems are presented for providing custom ring back tones to parties calling a wireline subscriber, in which an end office selectively connects the incoming call to a ring back tone server to hear a custom ring back tone until the wireline phone is answered, after which the incoming call is connected to the called wireline device.

Abstract: Methods and systems are presented for notifying a previously unsuccessful mobile calling party of a mobile called party's availability, in which a home location register causes an announcement to be sent to the unsuccessful calling party indicating that the called party is currently unavailable and that the calling party will be sent a short message when the called party becomes available. The called party status is then monitored and once the called mobile becomes idle or active, the HLR facilitates, utilizing a short message service center, sending a short message to the caller indicating that the called party is available to receive a call.

Abstract: The present Inter-System Message Delivery System increases the SMS text message delivery success rate. When a mobile subscriber station roams outside of the confines of the cell in which it is presently registered, the delivery of SMS messages to mobile subscriber stations fails, since the mobile subscriber station is not present in the Serving Mobile Switching Center to receive the SMS message. This is particularly common when the mobile subscriber station is moving within the confines of a border cell or multiple cells of a Border Mobile Switching Center and is not yet registered at this Border Mobile Switching Center. The SMS message delivery process initiates a page to the mobile subscriber station via inter-system or inter-Mobile Switching Center paging.

Abstract: A method is provided for paging a mobile station (40) served by a wireless telecommunications network (A). The method includes: remembering a last known location of the mobile station (40); selecting a paging strategy based upon the last known location of the mobile station (40), the paging strategy defining a number of page attempts and a region to be paged with each attempt; and, selectively paging the mobile station (40) over the wireless telecommunications network (A) in accordance with the selected paging strategy when the mobile station (40) is sought.

Abstract: A system and method for providing Custom Ring Back Tones (CRBTs) to calling party terminals calling called party wireless terminals in a wireless communications network is provided. A Gateway Switching Node connected provides a centralized interface between the PSTN and the switching nodes serving the called party terminals. The Gateway Switching Node connects a CRBT Server with the calling party terminals to provide the CRBTs thereto.

Abstract: A method is provided for paging a mobile station (40) served by a wireless telecommunications network (A). The method includes: using a plurality of band-classes to selectively communicate with the mobile station (40); remembering which one of the plurality of band-classes was last used to communicate with the mobile station (40); and, selectively paging the mobile station (40) over the wireless telecommunications network (A) when the mobile station (40) is being sought, the paging covering at least the remembered band-class for the mobile station (40) being paged.

Abstract: The present invention provides a method for sending a message to a calling phone when a called phone aborts an incoming call request. A mobile unit receives a call request from a calling phone. The communication network determines that the mobile unit has aborted the call request during ringing. For example, the mobile unit may abort the call request by pressing a predetermined key, such as the <END> key, on the mobile unit. The communication network alerts the calling phone that the mobile unit aborted the call request during ringing. The network can play a message to the calling phone that the mobile unit has aborted the call request during ringing, and the message can include additional information, such as the expected length of time that the mobile unit will be unavailable or other predetermined messages.

Abstract: A mobile telecommunications system includes a serving system and a home location register which yields MIN-free invoke response messages authreq, asreport, and afreport if shared secret data is shared with the serving system. This is true even if the mobile identification number is required to compute an authentication response and the mobile subscriber identification in the invoking message did not include the mobile identification number.
