An example method is provided in one example embodiment and may include receiving a session request for a user equipment (UE) at a node, wherein the session request includes a timestamp for the UE and a retry count; determining if the session request is a stray session request; and maintaining session information for an existing session for the UE at the node if the session request is a stray session request. The method can include identifying the received session request as a stray request if the timestamp received in the request is less than a timestamp stored for an existing session for the UE. The method can also include identifying the received request as a stray request if the timestamp received is equal to the timestamp stored for the existing session and if the retry count received is less than or equal to a retry count stored for the session.

System and method for handling stray session requests in a network environment

The present disclosure is directed at systems, methods and media for providing bearer call-back services for bearers that have been rejected or pre-empted by a network apparatus in a core network. In some embodiments, if a network apparatus enters a state in which it becomes necessary to reject or pre-empt a bearer associated with a user equipment (UE) (e.g., due to load conditions in a radio access network, the core network, or an application server), the network apparatus can send to the UE a call-back message when the network apparatus exits the state that precipitated the bearer rejection or pre-emption. By sending a call-back message, the network apparatus can save the UE from multiple unsuccessful attempts to establish a bearer, or from waiting an unnecessarily long time before establishing a bearer.

Systems and methods for implementing bearer call-back services

In general, techniques are described for providing a continuous feedback system that dynamically updates data collection criteria and subscriber policies based on aggregated subscriber-specific and network usage data. For example, a method includes applying one or more subscriber specific policy and charging control (PCC) rules to network traffic to collect network traffic data for a plurality of subscribers, aggregating the network traffic data, and determining, based on the aggregated traffic data, whether subscriber independent data collection criteria need to be updated. The method may also include, responsive to determining that the data collection criteria need to be updated: updating the data collection criteria, translating the updated data collection criteria from updated subscriber independent data collection criteria into updated subscriber specific PCC rules, and applying the updated subscriber specific policy and charging control rules to additional network traffic to collect additional network traffic data.
