1. A method of communicating messages in communication system, comprising:

  • receiving in a processor of a multiprocessor computing system a first communication message from a logical scalable unit (LSU) frontend component, wherein the first communication message was sent by the LSU frontend component in response to the LSU frontend component receiving a message from a first client component in response to the first client component determining that a user equipment set-up, modified, or terminated a VoiP call;

    determining, via the processor, whether session information relating to the received first communication message may be obtained from a session store;

    using session information included in the session store to make a policy decision in response to determining that session information relating to the received first communication message may be obtained from the session store;

    using session continuity information included in the received first communication message to determine the session information, and using the determined session information to make the policy decision, in response to determining that session information relating to the received first communication message may not be obtained from the session store, wherein the session continuity information includes information for maintaining session continuity for select services in the event of a failure without replicating session stores, including at least one of a session continuation (SC) parameter or a Session-Continuity Attribute-Value-Pair (AVP);

    generating and sending a second communication message to the LSU frontend component based on the policy decision; and

    generating and sending a third communication message that includes updated session continuity information to the LSU frontend component.
