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.
