Abstract: Communication networks and associated methods are disclosed that provide third party charging for SIP sessions. A communication network of the invention comprises a session control function (e.g., an IMS CSCF), a network node (e.g., an IMS application server), and a charging system. The session control function serves a SIP session initiated between a first and second party. The network node identifies a third party to charge for the session. The network node includes a third party identifier for the third party in a SIP message for the session, and transmits the SIP message to the session control function. The session control function generates a charging message, maps the third party identifier to the charging message, and transmits the charging message that includes the third party identifier to the charging system. The charging system then initiates charging of the session to the third party based on the third party identifier.

Abstract: In a telecommunications network a method of detecting unwanted (spam) messages. The content of a suspected spam message is analyzed to determine if the weighted properties and weighted sums of properties of the message exceeds a threshold. If these weighted sums exceed a threshold, the message is treated as a spam message and is subject to human analysis to improve the quality of the weighting factors and the properties that are used in the analysis.

Abstract: In a telecommunications network, method and apparatus for blocking unwanted messages (spam). Messages are first examined by a fast process which uses rules and data tables to determine whether a message can be passed or is potentially a spam message. If the message is potentially a spam message, the message content is analyzed by a deep process. Advantageously, most messages can be passed or blocked quickly and extensive data processing is required only for the few messages which cannot be categorized by the fast process.

Abstract: An intelligent-networked telecommunication system for audio playing of Electronic Mail ( E-Mail ) messages uses the Service Control Point (SCP) of the Intelligent Network (IN) to route e-mail messages directed to subscribing customers to the customer's telephone number when the e-mail header matches the limitations stored in the subscribing customer's profile. The text of the e-mail message is converted to an audio message which can either be heard by the customer when a call is answered, or stored on an answering machine or in a voice mailbox. The present-inventive Notifying and Hearing Selective E-Mails (NHSE) system and method also includes features such as the subscribing customer being able to specify that audio e-mail messages will be truncated to a specified length, sending a special Caller ID message identifying the e-mail sender and subject of the message when the customer also has Caller ID service, and preceding the transmission of the audio e-mail message with a distinctive ringing pattern, to allow a subscribing customer the option of going off-hook to listen to the message, or allow the call to go directly to voice mail or an answering machine.

Abstract: A subscriber screening system for screening operator assisted calls that is consistent with a new intelligent network interface and protocol standard. This subscriber screening system provides various significant data to a network database, from the operator service position station, which then either allows or disallows the operator assisted call and it also provides some information to the operator service position station about possible alternative ways of structuring the call.
