System and method for node selection based on mid-session and end-session event information

An apparatus comprising:

• a first communication interface comprising a transmitter and a receiver, the first communication interface configured to communicate using a first communication protocol to obtain notification of a first post-establishment event associated with a first communication session, wherein the first communication session relates to a first client computing device, wherein the first post- establishment event comprises at least one of a mid-session event and an end-session event;
• a second communication interface comprising a transmitter and a receiver, the second communication interface configured to:
• receive a request via a second communication protocol for a second communication session to be established for the first client computing device;
• and
• communicate identification information of one or more network elements selected for use in the second communication session;
• and
• processing logic comprising at least one processor, the processing logic configured to perform an operation, the operation comprising:
• determining, based on the first post-establishment event, state information identifying a first plurality of network elements involved in the first communication session;
• storing the state information;
• retrieving the state information based on the request for the second communication session to be established;
• and
• selecting at least one of the one or more network elements from the first plurality of network elements for the second communication session based on the retrieved state information.

At least one computer-readable non-transitory media comprising one or more instructions that when executed by a processor cause performance of operations comprising:

• obtaining, by a first network element comprising processing logic, notification of a first post-establishment event associated with a first communication session, wherein the first communication session relates to a first client computing device, wherein the first post-establishment event comprises at least one of a mid-session event and an end-session event, and wherein the first post-establishment event is communicated to a routing agent using a first communication protocol;
• determining, based on the first post-establishment event, state information identifying a first plurality of network elements involved in the first communication session;
• storing the state information;
• receiving, by the first network element, a request via a second communication protocol for a second communication session to be established for the first client computing device;
• retrieving the state information based on the request for the second communication session to be established;
• selecting, by the first network element, one or more network elements from the first plurality of network elements for the second communication session based on the retrieved state information;
• and
• communicating, by the first network element, identification information of the one or more network elements selected for use in the second communication session.
