Abstract

A process and system for implementing a dynamic roaming public land mobile network (PLMN) for at least one wireless network and at least one wireless device includes determining with a processor that at least one wireless device would benefit from modification of a public land mobile network (PLMN) based on at least one of the following: the at least one wireless device having poor wireless service performance, a change in wireless service rates for a wireless service carrier, reduced wireless service from a wireless service carrier, and a change in geographic location of a user of the at least one wireless device. Thereafter, the process and system updating a public land mobile network (PLMN) for the least one wireless device.

First claim

The invention claimed is:

1. A system configured to implement a dynamic roaming public land mobile network (PLMN), the system comprising a processor configured to:
receive at a processor at least one of: (i) wireless service quality information from a wireless network for at least one wireless device, (ii) wireless service rates for a wireless carrier, (iii) wireless carrier service information indicating reduced wireless service provided by a carrier for a geographic region; and (iv) geographic location information from the wireless network for at least one wireless device;
determine that at least one wireless device would benefit from modification of the PLMN based on at least one of: (i) the wireless service quality information, (ii) a change in wireless service rates for a wireless service carrier, (iii) reduced wireless service from a wireless service carrier, and (iv) a change in geographic location of a user of the at least one wireless device; and
update the PLMN for the least one wireless device based on at least one of: (i) the service quality information, (ii) the change in wireless service rates for the wireless service carrier, (iii) reduced wireless service from the wireless service carrier, and (iv) the change in geographic location of the user of the at least one wireless device.

2. The system configured to implement the dynamic roaming PLMN of claim 1 , wherein:
the processor is further configured to send a command to modify the PLMN for the at least one wireless device, the at least one wireless device comprising:
a wireless transceiver configured to receive the command from the processor to modify the PLMN; and
a wireless processor configured to modify the PLMN in response to the command received from the processor.

3. The system configured to implement the dynamic roaming PLMN of claim 2 , wherein:
the command comprises an over-the-air (OTA) command to the at least one wireless device that modifies the PLMN.

4. The system configured to implement the dynamic roaming PLMN of claim 2 , wherein:
the at least one wireless devices includes a wireless transceiver configured to receive the command from the processor to modify the PLMN; and
the wireless device includes a wireless processor configured to modify the PLMN in response to the command received from the processor.

5. The system configured to implement the dynamic roaming PLMN of claim 4 , wherein:
the wireless service quality information is received by the processor from the at least one wireless network from at least one of: a switch implemented by the at least one wireless network, a Home Location Register (HLR) implemented by the at least one wireless network, a home subscriber server (HSS) implemented by the at least one wireless network, a Unified Data Management (UDM) implemented by the at least one wireless network, a wireless service quality information processor implemented by the at least one wireless network, a wireless service quality information server implemented by the at least one wireless network, and the at least one wireless device that is receiving wireless service from the at least one wireless network.

6. The system configured to implement the dynamic roaming PLMN of claim 4 , wherein:
the wireless service quality information comprises at least one of: whether the at least one wireless device is registered to a Radio Access Network, a current cell tower identification (ID) that the at least one wireless device connects, a Location Area Code (LAC) for the at least one wireless device, a signal strength (dB) for the at least one wireless device, and/or the at least one wireless network, a Signal-to-Noise Ratio (SNR) for the at least one wireless device and/or the at least one wireless network, an LTE RSSI (Received Signal Strength Indicator) for the at least one wireless device and/or the at least one wireless network, an LTE RSRQ (Reference Signal Received Quality) for the at least one wireless device and/or the at least one wireless network, an LTE SINR (Signal to Interference & Noise Ratio) for the at least one wireless device and/or the at least one wireless network, an LTE CQI (Channel Quality Indicator) for the at least one wireless device and/or the at least one wireless network, a RSRP (Reference Signal Received Power) for the at least one wireless device and/or the at least one wireless network, a data latency for the at least one wireless device and/or the at least one wireless network, jitter for the at least one wireless device and/or the at least one wireless network, and a data throughput for the at least one wireless device and/or the at least one wireless network.

7. The system configured to implement the dynamic roaming PLMN of claim 1 , further comprising:
the processor being further configured to receive geographic location information from the at least one wireless network for the at least one wireless device;
a database configured to store the geographic location information related to the at least one wireless device;
the processor further configured to analyze the geographic location information related to the at least one wireless device; and
the processor further configured to determine that at least one wireless device would benefit from modification of the PLMN.

8. The system configured to implement the dynamic roaming PLMN of claim 7 , wherein:
the geographic location information comprises at least one of: a current cell tower identification (ID) that the at least one wireless device connects, a Location Area Code (LAC) for the at least one wireless device, and a location determined by a global navigation satellite system (GNSS) with a location determination device implemented by the at least one wireless device.

9. The system configured to implement the dynamic roaming PLMN of claim 1 , further comprising:
the processor being further configured to receive wireless carrier service information indicating reduced or limited wireless service provided by a particular carrier for particular geographic region;
a database configured to store the wireless carrier service information related to the at least one wireless device;
the processor further configured to analyze the wireless carrier service information related to the at least one wireless device; and
the processor further configured to determine that at least one wireless device would benefit from modification of a public land mobile network (PLMN).

10. The system configured to implement the dynamic roaming PLMN of claim 1 , further comprising:
the processor being configured to receive wireless service quality information from at least one wireless network for the at least one wireless device;
the processor being further configured to receive geographic location information from the at least one wireless network for the at least one wireless device;
