Rapporteur:  Mr. Schmitt, Peter

The present document analyses various EPC race conditions scenarios and scenarios with hanging session or bearer contexts in EPC nodes, and assesses whether to improve the existing protocols and/or specifications for effective handling of these scenarios. The specification updates, if needed, may consist in EPC (GTP-C, PMIP and/or Diameter) signalling improvements, recommendations on how to minimize the occurrences of the issues, and/or clarifications on how the EPC nodes should behave in these scenarios.
