1. A device, comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations comprising:
receiving from an other device of a plurality of peer devices communicating over a network, in a peer-to-peer transaction, configuration information including status data of the network, wherein the other device operates in a first cell of the network, and wherein the first cell is associated with a first radio access technology;
transmitting service requests to the first cell;
determining a number of consecutive failed service requests transmitted to the first cell, wherein a failure of a service request corresponds to expiration of a predetermined time period without a response to the service request;
responsive to a determination that the number of consecutive failed service requests exceeds a threshold number:
determining an overload mitigation time duration, wherein the overload mitigation time duration is associated with the first radio access technology, and
performing a first cell-selection procedure to select a second cell associated with a second radio access technology during the overload mitigation time duration, the second cell being different from the first cell; and
responsive to a determination of an expiration of the overload mitigation time duration:
performing a second cell-selection procedure to select a third cell associated with the first radio access technology, and
transmitting additional service requests associated with the first radio access technology,
wherein the threshold number and the overload mitigation time duration are based on the configuration information and on network resource usage data received from the first cell.
