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 &#x3c;END&#x3e; 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.

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

Enhanced mobile station paging in a wireless telecommunications network

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.
