Benefits of technology

[0004] From the foregoing, it may be appreciated by those skilled in the art that a need has arisen for an improved communications approach that provides improved signaling for implementing policy on behalf of selected end users. In accordance with on

Problems solved by technology

In some environments, policy, locale, or service level may be unknown, inaccurate, or ambiguous at various times during a communication session.
This deficiency may create synchronization issues where an end user may be incorrectly billed or where other users may have access to certain information that should not be made available to them or where

Embodiment Construction

[0015]FIG. 1 is a simplified block diagram of a communication system 10 for providing enhanced packet processing (e.g. for purposes of security or billing) in a network environment. Communication system 10 includes an end user 12, a radio access network (RAN) 16, a serving general packet radio service (GPRS) support node (SGSN) 18, and an internet protocol (IP) network 20. Additionally, communication system 10 includes a gateway GPRS support node (GGSN) encapsulation / decapsulation element 30, a GGSN policy element 32, and a client services packet gateway (CSPG) 14. GGSN policy element 32 may be coupled to a policy decision function (PDF) 50. In addition, CSPG 14 may include a loggen element 24, a known user table (KUT) 26, and a quota manager element 36. Communication system 10 may additionally include a billing system element 40 that may include a quota server 42 and a billing mediation agent (BMA) 44.

Abstract

An apparatus for charging in a network environment is provided that includes an access gateway encapsulation/decapsulation element operable to establish one or more packet data protocol (PDP) links on behalf of an end user and to perform encapsulation and decapsulation operations for one or more of the links associated with the end user. The access gateway encapsulation/decapsulation element is further operable to interface with a client services packet gateway (CSPG) that is operable to provide enhanced packet processing for the end user for requested information. The apparatus also includes an access gateway policy element operable to interface with the CSPG. The access gateway encapsulation/decapsulation element and the access gateway policy element cooperate to use one or more inter-module headers in order to coordinate the enhanced packet processing for one or more communication flows associated with the end user.

Description

TECHNICAL FIELD OF THE INVENTION [0001] This invention relates in general to the field of communications and, more particularly, to a system and a method for service tagging for enhanced packet processing in a network environment. BACKGROUND OF THE INVENTION [0002] Networking services have become increasingly important in today's society. One feature of networking services relates to client or source awareness. Certain services, functions, or capabilities may be provided to a group of end users or to clients based on a corresponding source profile or policy. Devices or components within a network must generally be able to identify such a profile or policy before offering selected enhanced services, functions, or capabilities to a targeted group of end users. Accordingly, sufficient information must be made available at specific times in order to allow for an accurate identification of a flow and, further, to bill for and / or process that flow accordingly. [0003] As the subscriber bas...
