Abstract: Duration based accounting for a packet data service, for example offered as a prepaid mobile IP (MIP) service through a public mobile wireless communication network, uses last detected user activity to determine the end of each session for accounting purposes. The accounting policy or algorithm defines user activity so as to include receipt of signaling related to the MIP session, such as signaling related to a termination by the user or the user's mobile station, in addition to packet data routed for the mobile station. If a session ends due to a network termination, e.g. binding expires or the network disconnects upon prepaid quota exhaustion, then the last user activity used for accounting purposes is the last data packet communication to/from the mobile station or the last received MIP session-related signaling message. For example, if MIP signaling terminates the session, then the session duration runs until receipt of that signaling.

Abstract: A method and system is disclosed for facilitating voice mailbox operations for a mobile phone capable of operating in both a CDMA and a GSM environment. The system has at least first and second switching points and a global switching point in communication with a control point. Upon a first switching point detecting a busy/no answer condition for a request to terminate a call to a called station (the call originating from a calling station), the first switching point forwards the terminating call to a temporary, unique forward-to number belonging to the global switching point which then sends at least one message to the control point, the at least one message identifying the unique forward-to number designating a voice mailbox. The control point then identifies the second switching point from the unique forward-to number and sends a first call treatment message instructing the second switching point to apply voicemail treatment at a voice mailbox linked thereto.

Abstract: A method and system for facilitating prepaid mobile messaging. Mobile messages are forwarded to their intended one or more destinations before the debit account of the one or more prepaid mobile messaging subscribers associated with the mobile message are debited.

Abstract: A telephone call processing arrangement establishes a path between a called switching center and an audio content server in response to receipt of an incoming call to a subscriber. A preselected audio presentation is transmitted from the audio content server to the caller in lieu of audible ringback signals. A call leg is then extended from the called switching center to the called or forwarded station and, in response to an answer of the call by the called party, the audio content server is disconnected from the caller while the caller is connected to the call leg. Such provision may be employed for a mobile or landline subscriber.
