System and method of implementing an interactive callback feature in a radio telecommunications network

摘要

A system and method in a radio telecommunications network for interactively providing a calling party with a choice of call handling options when a called mobile station (MS) is either busy or inactive. When a call is received for the called MS in the network, a home location register (HLR) determines the status of the called MS (i.e., whether the called MS is available, inactive, or busy). If the called MS is inactive or busy, the status is sent to a service control point (SCP) which generates a plurality of call handling options based upon the determined status of the called MS. The call handling options are provided to the calling party in an interactive prompting process which may be in the form of a menu display or voice prompting. The calling party then selects a call handling option which is forwarded to the SCP. The calling party may instruct the network to automatically set up a call with the called MS if the called MS is reactivated within a specified period of time. The SCP determines actions required to execute the selected call handling option, and executes the determined actions. Call setup between the calling party and the called MS is triggered when the called MS registers with the network. If the time period expires before the called MS registers, the calling party is notified and may extend the time period or record a voice mail message.
