This disclosure relates to a system and method for routing data packets adaptively in a communication system. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks can continue to exponentially increase. One way to accommodate increased data traffic and provide high quality data communication services to end users is by utilizing network resources efficiently. This disclosure provides systems and methods for efficiently utilizing network resources by providing adaptive intelligence to data packet routing systems.

Adaptive intelligent routing in a communication system

A method is provided in one example embodiment and includes establishing a control channel between a first entity associated with an access network and a second entity associated with a core network. The control channel is associated with a session identifier identifying a user session. The method further includes receiving policy information associated with the user session from the second entity using the first control channel. The policy information is indicative of one or more policies to be applied in the access network to user data associated with the user session.

Localizing a mobile data path in a radio access network under control of a mobile packet core in a network environment

Systems and methods are provided that allow network resources to be shared across geographical distances. This can be achieved by changing the resources available for establishing and handling call or data session processing in an area. A mobility management device can alone or in combination with a DNS server change the size or the resource pool available in some embodiments. The change in resources can be dynamic according to certain predefined conditions or can be setup beforehand to account for daily demand. This sharing of resources can allow more efficient usage of resources available across a geographic region, rather than needed to over-provision each region to account for peak demands.

Provisioning available network resources

A method is provided in one example embodiment and includes providing a multi-radio connectivity service to a mobile subscriber, and managing the multi-radio connectivity service for the mobile subscriber. The managing can include: providing admission control; providing privileged subscriber access at a plurality of WiFi access points; providing signaling for quality of service (QoS) equivalence across a WiFi network and a mobile network; and distributing certain traffic based on a policy.

System and method for resource management for operator services and internet

Methods and systems for providing a dynamic and real time load factor that can be shared with other network elements is disclosed. The load factor can be used in determining the relative load among a set of network elements and in distributing new sessions requests as well as existing session on the set of network elements. The load factor can also be used for determining to which network element a user equipment is handed off. The dynamic load factor can also be shared amongst network elements to determine how the load is balanced among the network elements, such as a mobility management entity (MME).

Dynamic load balancing in a communication network

Methods and systems for providing interconnection between network operation environments are disclosed in some embodiments. This can include providing interoperability between 3GPP and 3GPP2 standards environments. In one embodiment, a method is disclosed that includes receiving a request from a mobile device for service at a gateway, determining a mode of operation for the mobile device by inspecting an incoming message, wherein the mode of operation includes 3GPP and 3GPP2, establishing a connection using a proxy mobile internet protocol (PMIP), where the type of connection established is dependent on the mode of operation, providing an IP address to a mobile device based on the mode of operation and the parameters associated with the mode of operation, and communicating with an authentication, authorization, and accounting (AAA) server operating in accordance with the mode of operation.

Providing proxy mobile IP over a communication network

Systems and methods are provided to allow detection of the load conditions on network devices. The load detection can occur using a mobility management device to track establishment of sessions and attempts at session establishment to determine the loading conditions on various network devices. This information can then be used by a selection logic to determine which devices are selected to send session establishment messaging for new session establishment requests. This can provide quicker setup times as highly loaded network devices or network devices experiences other failures are selected less until conditions are back to normal.

Detecting overloads in network devices

Systems and methods for providing an interface to communicate policy information from a policy server to a policy enforcement point are presented. An external policy server is used to implement and provide various policies to a policy enforcement point for enforcement on subscriber sessions and traffic flows of a mobile subscriber. A policy enforcement point can request instructions from the policy server using an access-request message and receive from the policy server unsolicited instructions with a change-of-authorization message. Policies for application to a subscriber session or traffic flow are included in the message from a policy server to the policy enforcement point. Other messages such as a disconnect message are used to terminate a subscriber session.
