Abstract
Aspects of the subject disclosure may include, for example, detecting at a mobile device a communication failure of a data connection between the mobile device and a source core network of a plurality of core networks available to the mobile device, the mobile device communicating with a respective core network of the plurality of core networks through a radio access network, selecting a destination core network of the plurality of core networks, and handing off the data connection from the source core network to the destination core network. Other embodiments are disclosed.
Claims20
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, the operations comprising:
- connecting the device to a radio access network, wherein the connecting comprises communicating with a first core network of a plurality of core networks available to the device;
- communicating with a remote network through the first core network;
- identifying a degradation in a key performance indicator for the communicating with the remote network through the first core network;
- selecting a second core network of the plurality of core networks, wherein the first core network is configured to utilize at least one communications technique that the second core network does not utilize and the at least one communications technique comprises a software definable network including a plurality of network slices;
- initiating communication with the second core network;
- communicating with the remote network through the second core network to eliminate the degradation in the key performance indicator for the communicating with the remote network;
- testing if the degradation in the key performance indicator due to a communication failure of the first core network continues;
- and
- reinitiating communication with the first core network by the device responsive to the testing.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
- attaching a mobile device to a radio access network operated by a service provider;
- communicating, through the radio access network, with a first packet core network of a plurality of packet core networks operated by the service provider;
- communicating with a remote network source, wherein the first packet core network provides packet data communication between the remote network source and the mobile device;
- identifying a communication degradation due to a communication failure of the first packet core network, wherein the identifying comprises comparing a selected communication parameter with a predetermined threshold value;
- selecting a second packet core network of the plurality of packet core networks operated by the service provider, wherein the selecting is responsive to the selected communication parameter failing to exceed the predetermined threshold value, and wherein the first packet core network utilizes at least one communications technique that the second packet core network does not utilize, and wherein the at least one communications technique comprises a software definable network including a plurality of network slices;
- initiating communication with the second packet core network by the mobile device through the radio access network;
- communicating with the remote network source, wherein the second packet core network provides packet data communication between the remote network source and the mobile device;
- testing communication performance of the plurality of packet core networks;
- and
- selecting a current-generation technology packet core network.
