Abstract

Methods and apparatus to migrate a mobile device from a first virtual private mobile network to a second virtual private mobile network are disclosed. An example apparatus includes a processor and a memory including instructions that cause the processor to perform operations including determining, based on a set of latency routing rules, that a communication transmitted via the first virtual private mobile network is a latency sensitive communication. In response to determining the communication is a latency sensitive communication, the mobile device that originated the latency sensitive communication is identified. The mobile device is communicating via the first virtual private mobile network. Example operations also include migrating the mobile device from the first virtual private mobile network to the second virtual private mobile network wherein the second virtual private mobile network is configured to reduce the latency of the latency sensitive communication.
