A call processing architecture treats a call connection as having two halves an originating half and a terminating half. An agent is associated with each call half, the originating agent being assigned by a switching center of a telecommunications system to establish the originating half of a call. The originating agent interacts with a translator and router to process the dated digits for a call to route the call to a terminating agent, the terminating agent establishing the terminating half of the call to complete the call connection. An agent interworking protocol (AIP) provides a generic superset protocol containing the common elements and unique elements for all call types so that an originating agent converts its call messages to the AIP and is connected to a terminating agent via an AIP connector, the terminating agent converting the AIP formatted call messages to the native protocol of the terminating agent. Agents for different call types are each able to convert call messages to or translate call messages from the agents's unique protocol to the AIP format and each type of agent does not need to know the type of agent being connected to as communication with other agents is via the AIP.

Agent interworking protocol and call processing architecture for a communications system

A generic telecommunications system and associated methods are disclosed herein. Such generic telecommunications system provides for, among other things, a call processing application that can be used with telecommunications systems that incorporate varying different technologies and standards. Such call processing applications may, for example, include a home location register, visitor location register and mobile switching center elements. In addition, the call processing application may include an application provider and/or a radio controller elements. Those elements are preferably implemented as software entities including one or more software objects. As software entities of the same application, those elements may readily communicate with, and invoke operations associated with, one another. Further, as disclosed herein, software entities of the call processing application may also readily communicate with, and invoke operations associated with, software entities of other applications. In addition, agents associated with the switchign center, may faciliate the call processing of calls originating and terminating in accordance with varying access technologies.

Generic wireless telecommunications system

In one aspect of the present invention, an integrated authentication center is provided that may be used in an exemplary integrated wireless telecommunications system (14). The integrated authentication center includes an application process, such as a call processing application (54), that includes a plurality of software objects such as a home location register (44) and an authentication center (42). The home location register (44) is implemented in one of the plurality of software objects of the application process and initiates the generation of an authentication set, such as authentication triplets. The authentication center (42) is also implemented in one of the plurality of software objects of the application process and generates the authentication set in response to the home location register (44).

Integrated authentication center and method for authentication in a

In one aspect of the present invention, an application provider, such as a mobile application part provider (52), is provided that includes a table (210), a router (200) and a message converter (220). The table (210) stores information corresponding to a sub-system, such as a visitor location register (46) or a home location register (44), of a first node, such as an integrated wireless telecommunications switch (14). The router (200) analyzes an application part message, such as a mobile application part message, that originated from the first node and compares the information stored in the table to the destination of the application part message to determine if the application part message is destined for the sub-system of the first node. The router (200) communicates the application part message to the first node if the application part message is destined for the sub-system of the first node. The message converter (220) converts the application part message to a transaction capability application part message if the router (200) determines that the application part message is not destined for the sub-system of the first node.

Application provider and method for communication

A generic telecommunications system and associated call processing architecture is disclosed herein. Such generic telecommunications system provides for, among other things, a call processing application that can be used with telecommunications systems that incorporate varying different technologies and standards. Such call processing applications may, for example, include a switching center, such as a mobile switching center. The switching center may include multiple agents to process calls from one access technology to another access technology. For example, in accordance with an exemplary embodiment, a first agent is associated with the origination of a call connection while a second agent is associated with the destination of a call connection. The first agent is operable to convert a call setup message from a format consistent with a first access technology or standard, such as GSM, to a standard format. The second agent is operable to convert from the message from the standard format to a second format that is consistent with a second access technology or standard, such as CDMA. As a result, a single telecommunications switch may switch a call from a GSM subscriber to a CDMA subscriber.
