A method, computer readable medium and apparatus for transmitting signaling information within payload traffic. The method parses a certificate received from a service provider to obtain service imprint information associated with a mobile service, inserts a service control parameter derived from the service imprint information into a packet header, and forwards the packet header within payload traffic to a policy charging and enforcing function.

Dynamic in-band service control mechanism in mobile network

A method and apparatus for providing a virtual network function in a visited network are disclosed. For example, the method receives an attach request or a handover for a user endpoint device, determines a home network for the user endpoint device, receives a profile of the user endpoint device, determines a policy for providing a service to the user endpoint device in accordance with the profile, determines a set of virtual network functions needed for providing the service to the user endpoint device in accordance with the policy, grants the attach request or the handover, designates for each virtual network function of the set of virtual network functions that is needed for providing the service, a corresponding virtual network function for serving the user endpoint device at a location of the user endpoint device, and provides the service to the user endpoint device via the set of virtual network functions.

Method and apparatus for providing a virtual network function in a network

Facilitating flexible maximum transmission unit packet core design in a communications network is provided herein. A system can comprise a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can comprise receiving a first transmission unit setting from a first network device. The first transmission unit setting can indicate a size of a largest network layer protocol data unit that is able to be communicated in a single network transaction by the first network device. The operations can also comprise setting, at the device, a configuration of the first network device to the first transmission unit setting. Further, the operations can comprise sending first communication packets to the first network device using the first transmission unit setting and second communication packets to a second network device using a second transmission unit setting different from the first transmission unit setting.

Legacy network maximum transmission unit isolation capability through deployment of a flexible maximum transmission unit packet core design

A method, computer readable medium and apparatus for transmitting signaling information within payload traffic. For example, the method parses a certificate received from a service provider to obtain service imprint information associated with a mobile service, inserts a service control parameter derived from the service imprint information into a packet header, and forwards the packet header within payload traffic to a policy charging and enforcing function.

Aspects describe using a Policy Access Gateway that can facilitate scalability within a communication network and that can provide a solution to deploy an enhanced policy gateway. The Policy Access Gateway can enhance standard defined Diameter Routing Agent (DRA) functions with session binding mechanisms. Further, the Policy Access Gateway is scalable and can be deployed in a very large network that supports hundreds of millions of users. Further, the Policy Access Gateway can provide additional policy information to enable policy information consolidation and caching capabilities.

Scalable policy deployment architecture in a communication network

A policy application server and methods for use are described. The policy application server is a logical element of a policy-based control and charging system for a mobile data service network. The policy application server is configured to manage policies including creating, revising, formatting, and provisioning of policies. The policy application server is configured to assemble policy rules from policies and context data. Context data includes subscriber and service information needed to make a particular policy rule. The policy application server gathers context data from one or more network databases. The policy application server is configured to send policy rules to select ones of a plurality of policy decision engines. The policy application server manages the storing of policies, policy rules and formatted context data in select ones of a plurality of policy repositories.

Policy application server for mobile data networks

A system that incorporates the subject disclosure may perform, for example, operations including monitoring events relating to activities by a plurality of communication devices, content sources supplying content to the plurality of communication devices, and network conditions during content exchanges between the plurality of communication devices and the content sources, tagging the events to generate tagged events, detecting an event initiated by a communication device of the plurality of communication devices, obtaining tagged event information from the tagged events according to the event detected, generating a policy according to the tagged event information, and transmitting the policy to a policy enforcement function system to facilitate a communication session between the communication device and the content source according to the policy. Other embodiments are disclosed.

Method and apparatus for policy management in a communication system

A downstream device in a network may monitor and collect data on its condition, including detecting overload conditions, and transmit such data to an upstream network device. The upstream network device may select a best downstream device for a particular traffic flow based on condition data received from downstream devices and transmit the traffic flow to the selected downstream device. A network management server may be configured to perform similar functions, instructing network devices on how to transport data through a network based on condition data received from such devices.

Long term evolution network dynamic overload management

Aspects describe using a Policy Access Gateway to facilitate scalability within a communication network and to provide a solution to deploy an enhanced policy gateway. The Policy Access Gateway can enhance standard defined Diameter Routing Agent (DRA) functions with session binding mechanisms. Further, the Policy Access Gateway is scalable and can be deployed in a very large network that supports hundreds of millions of users. Further, the Policy Access Gateway can provide additional policy information to enable policy information consolidation and caching capabilities.

A policy-enabled service gateway contains a gateway function and a local policy engine containing policies related to the functionality of the associated gateway function. New or updated policies may be provided to the local policy engine from a centralized policy server. The policies within the local policy engine are functionally related to the gateway function and provide for policy and/or charging enforcement associated with the gateway function. If the local policy engine does not contain a particular policy, it may request the policy from the centralized policy server. The local policy engine may choose to store the requested policy for future use.

System and method for policy-enabled mobile service gateway

A system and method for a mobile data access network to make policy control and charging decisions based on domain name queries. A mobile device sends a query about a domain name associated with a service a user of the mobile device wishes to engage. The access network carries the domain name query from a mobile device to a domain name server. The access network detects the domain name query and copies the queried domain name. The access network uses the queried domain name to make an incomplete policy decision. The policy decision is incomplete because one or more service data flow filters in the decision lack addresses for providers of the service. The access network detects a response to the domain name query and copies a service provider address from the response. The access network uses the service provider address to complete the policy decision.
