A method for wireless communication, the method comprising: employing a processor executing computer executable instructions stored on a computer readable storage medium to implement following acts: transmitting a request from a first network entity to a second network entity to establish a policy and charging control session for a user equipment accessing the first network entity; receiving from the second network entity a reference to a first plurality of predefined policy and charging control rules that defines a criterion for detecting an encapsulated packet flow and an event trigger for reporting a detected flow; accessing said first plurality of predefined policy and charging control rules; detecting the encapsulated packet flow by performing a packet flow optimization application using the first plurality of policy and charging control rules; transmitting an indication of the event trigger and a description of the encapsulated packet flow from the first network entity to the second network entity; and receiving a second plurality of policy and charging control rules at the first network entity from the second network entity for the policy and charging control session based on the encapsulated packet flow. employing a processor executing computer executable instructions stored on a computer readable storage medium to implement following acts: transmitting a request from a first network entity to a second network entity to establish a policy and charging control session for a user equipment accessing the first network entity; receiving from the second network entity a reference to a first plurality of predefined policy and charging control rules that defines a criterion for detecting an encapsulated packet flow and an event trigger for reporting a detected flow; accessing said first plurality of predefined policy and charging control rules; detecting the encapsulated packet flow by performing a packet flow optimization application using the first plurality of policy and charging control rules; transmitting an indication of the event trigger and a description of the encapsulated packet flow from the first network entity to the second network entity; and receiving a second plurality of policy and charging control rules at the first network entity from the second network entity for the policy and charging control session based on the encapsulated packet flow. transmitting a request from a first network entity to a second network entity to establish a policy and charging control session for a user equipment accessing the first network entity; receiving from the second network entity a reference to a first plurality of predefined policy and charging control rules that defines a criterion for detecting an encapsulated packet flow and an event trigger for reporting a detected flow; accessing said first plurality of predefined policy and charging control rules; detecting the encapsulated packet flow by performing a packet flow optimization application using the first plurality of policy and charging control rules; transmitting an indication of the event trigger and a description of the encapsulated packet flow from the first network entity to the second network entity; and receiving a second plurality of policy and charging control rules at the first network entity from the second network entity for the policy and charging control session based on the encapsulated packet flow.
