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. Once the mobile subscriber station is located, the bearer data for this mobile subscriber station is forwarded from the Serving Mobile Switching Center to the Border Mobile Switching Center in which the mobile subscriber station is presently located The mobile subscriber station is finally registered at the Border MSC.

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 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.

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.

This technique is applied in the circumstances where an intersystem page message, e. g. an IS-41 ISPAGE2 message, is received in a first border switching module. The intersystem page message may originate from a second border switching module. In this case, the network determines whether the second border switching module is manufactured by a different network provider than the first border switching module. If so, a routine to address inconsistencies in the location area parameter is implemented so that an efficient paging strategy can be invoked.

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

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.

This invention relates to a method and apparatus for improved, or optimized, handling of paging requests to a border switch from neighboring switches. More particularly, a technique is provided to reduce the adverse impact of paging requests on border switches while maintaining a high paging success rate. Data representing probabilities that mobile devices are within selected coverage areas, or cells, of the border switch is collected and maintained. The data is used as a basis to more efficiently page mobile devices throughout the selected coverage areas, or cells, of the border switch.

A method and apparatus for secure voice communication are provided. More particularly, the present techniques are directed to the introduction of voice security for mobile-to-mobile calls. The coding and decoding is accomplished by handset vocoders, in lieu of coding and decoding accomplished by the network. In this regard, when voice security is determined to be necessary, users select a secured transmission protocol and communicate the selection to the network. All coding and decoding is then performed only in the handsets, as opposed to the network. Moreover, the vocoders implemented, in at least one form, employ security encryption, so that only the two connected mobile users are able to understand the content of the voice transmission.
