Billing and OAM function integration in a mixed-switching environment

One or more non-transitory computer-storage media having computer-executable instructions embodied thereon for performing a method of efficiently transferring data that facilitates billing and operations functions associated with a telecommunications network, wherein the transfer enables communication of messages across a telecommunication network containing circuit-switched sub-network and packet-switched sub-network, and wherein the messages on packet-switched sub-network include both header portions and payload portions, the method comprising:

• via a circuit-switched sub-network providing access services, receiving at a proxy gateway a message from a first user;
• via a packet-switched sub-network providing connectivity services, receiving at the proxy gateway user information and application-server-registration information;
• communicating data that facilitates billing and operations functions from the proxy gateway to the application server;
• aggregating the data at the application server;
• communicating the aggregated data to at least one of a server configured to perform billing functions and a server configured to perform operations, administration and management (OAM) functions;
• and
• communicating the message from the proxy gateway to a second user on the circuit-switched sub-network.

A system for interfacing components in a wireless telecommunications network for the purpose of transferring data enabling business and operations management functions, the system comprising:

• a proxy gateway logically coupled to an application server, wherein the proxy gateway is situated between a circuit-switched network providing access services and a packet-switched network providing connectivity services;
• the application server, wherein the application server is part of the packet-switched network;
• and
• an interface that enables the transmission of data that facilitates business and operations management functions between the proxy gateway and the application server,
• wherein the interface receives additional information from a server configured to provide home-subscriber functions in order to enable communication of data facilitating business and operations management from the proxy gateway to the application server, and
• wherein the interface receives from the proxy gateway and communicates to the application server a mobile switching center code and at least one of a proxy identifier, a traffic restriction flag, and a packet data unit type.
