1. A method comprising:
receiving, by one or more servers, a network selection query associated with a user device after the user device relocates from a home network to a roaming network,
the network selection query including information relating to a geographic location of the user device within the roaming network; selecting, by the one or more servers and after receiving the network selection query, a plurality of virtual network elements based on a type of task to be performed by the user device,
the plurality of virtual network elements being located within the roaming network and functioning as physical network elements of the home network; selecting, by the one or more servers and based on a particular technique, a virtual network element of the plurality of virtual network elements,
the home network including one of an evolved packet core (EPC) network or an internet protocol (IP) multimedia subsystem (IMS) network; enabling, by the one or more servers, use of the virtual network element by the user device; receiving, by the one or more servers and from the user device, a data packet destined for the virtual network element; providing, by the one or more servers, the data packet to the virtual network element; determining, by the one or more servers, that the virtual network element is overloaded based on one of a latency activity value or a jitter activity value associated with the virtual network element; and directing, by the one or more servers, an addition of another virtual network element based on determining that the virtual net ark element is overloaded. |
