1. A method for processing a path switching request in a wireless network, comprising:
receiving, by a processor of a mobility management entity of a virtual machine on a first server, the path switching request from a user endpoint device; determining, by the processor, when the path switching request is for a regional hand-off between the virtual machine to another virtual machine; initiating, by the processor, a virtual machine move request for moving the virtual machine providing a mobility support function for a user of the user endpoint device, when the path switching request is for the regional hand-off, wherein the virtual machine and the another virtual machine each comprises a server with an instantiation of a serving gateway function, a mobility management entity function, a packet data network gateway function, a policy charging and rule function, an evolved packet data gateway function and an operator services function of an evolved packet core network for the user endpoint device, wherein the initiating the virtual machine move request comprises sending the virtual machine move request to a virtual machine manager that is a different server than the virtual machine and the another virtual machine and performs the moving from the virtual machine to the another virtual machine, updates a home agent of the user endpoint device, and sends a virtual machine move acknowledgement; determining, by the processor, when the virtual machine move acknowledgement is received; and performing, by the processor, a user plane update and providing a response to the path switching request, when the response to the virtual machine move request is received. |
