  • a processor; and

    a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

    forwarding requests associated with call processing sessions to a server of a network that stores subscriber data associated with subscribers of the network for processing by the server, comprising not storing respective identifier data of the requests associated with the call processing sessions that have been processed by the server;

    in response to detection of a first overload condition associated with the server, storing the respective identifier data of the requests associated with the call processing sessions that have been processed by the server after the detection of the first overload condition;

    receiving a request associated with a call processing session, wherein the request is to be directed to the server,in response to detection of a second overload condition associated with the server, determining whether identifier data of the respective identifier data has been previously stored for a previous request associated with the call processing session that has been processed by the server, andin response to determining that the identifier data has been previously stored for the previous request associated with the call processing session that has been processed by the server, forwarding the request to be processed by the server comprising assigning a priority to the request based on an amount of previous requests associated with the call processing session that have been processed by the server, wherein a first request associated with a first call processing session comprising a first amount of processing of previous requests associated with the first call processing session processed by the server is assigned a higher priority than a second request associated with a second call processing session comprising a second amount of processing of previous requests associated with the second call processing session processed by the server, and wherein the second amount is lower than the first amount.
