In one embodiment of a method of translating a RADIUS message to a Diameter message, an access request message in RADIUS is translated to a credit control request message in Diameter. In one embodiment of a method of translating a Diameter message to a RADIUS message, a credit control answer message is translated to an access accept message.

Method of converting between radius message and diameter messages

This invention relates to apparatus and a method for assembling and coordinating call data records from a plurality of network elements of an Internet Protocol Multimedia System call to generate charging information. A pre-biller stores an integrated charging record and accesses a rating engine to obtain the charging information to complete a charging data record. Advantageously, the information from a plurality of network elements is integrated into a combined charging data record.

An originating mobile switching center of an apparatus in one example handles one or more calls. A serving mobile switching center for a communication device on a call of the one or more calls passes control of the call to the originating mobile switching center. The originating mobile switching center triggers the call to a service node. The service node sends an initial trigger response to the originating mobile switching center that instructs the originating mobile switching center to redirect the call. The initial trigger response arms one or more triggers that support one or more services for the communication device. The one or more triggers comprise one or more of one or more switch based triggers and one or more subscriber based triggers exclusive of Calling_Routing_Addresss_Available, OAnswer, and ODisconnect triggers. Upon receipt of the initial trigger response, the originating mobile switching center encounters one or more of the one or more triggers and triggers the call to one or more other service nodes.

Call triggering to one or more service nodes upon receipt of initial trigger response

A method and apparatus for routing billing request and response messages to a billing server for serving calls by a particular subscriber. When the subscriber originates a call, an original billing request message is transmitted to an agent server. The agent server determines which billing server serves that subscriber and forwards the billing message to the selected billing server. The billing server responds to the request message with billing request data. Advantageously, this arrangement minimizes the problems of updating a large number of subscriber identification/billing server identification databases.

Call authorization and billing message routing capability

A mobile switching center of an apparatus in one example generates one or more triggered operations to a prepaid service node based on a connection with an intelligent peripheral component.

Generating one or more triggered operations to prepaid service node based on connection with intelligent peripheral component

This invention relates to a method and apparatus for charging and billing of Circuit Switch, Packet Switch, and IP Multimedia Subsystems in third generation telecommunication systems. The charges for a call are computed by a rating engine, a software system comprising data tables and a program for calculating charges from the parameters of the call, such as the calling and called numbers, the length of the call, and special charge items such as priority service. For calls whose billing cannot be deferred, referred to as on-line billing calls, the rating engine is accessed immediately. For calls whose billing can be deferred, referred to as off-line billing calls, the rating engine performs its function only when the rating engine is not busy rating on-line billing calls, for example, during periods outside the busy hour. Advantageously, only a single rating engine is required, and the capacity of that single rating engine is determined only by the busy-hour volume of on-line billing calls.

Pre-biller capability in enhanced charging collection function (CCF) applications

A method and apparatus for providing wireless intelligent network services to mobile stations currently being served by a mobile switching center (S-MSC) that is not wireless intelligent network capable. The call is routed through a wireless intelligent network capable MSC (O-MSC). When the O-MSC receives the call, it requests instructions from a service control point (SCP) which provides a list of triggers for call states requiring further SCP instructions. Advantageously, this arrangement avoids the use of a double connection, using a loop-around trunk, in the O-MSC, as is required in the prior art.
