Jamming mitigation in CBRS network
Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for managing service provider network nodes in a converged network by inserting mobile network UE information into WiFi network communications such that a WiFi control entity may, in response to determining that the UE-inserted information is indicative of a jamming condition at a Citizens Broadband Radio Service Devices (CBSDs) providing mobile network services to the UE, communicate the identification of such UE to various provider equipment such that CBSDs experiencing jamming signals may be identified and mitigation steps taken.
1. A method for managing service provider network nodes, the nodes comprising Citizens Broadband Radio Service Devices (CBSDs) configured for providing network services of the service provider to user equipment (UE) connected thereto, the method comprising:
receiving, at a WiFi controller configured to manage a plurality of service provider wireless access points (WAPs) providing network services of the service provider to UE connected thereto, WiFi frames from UE including WiFi frames indicative of a CBSD jamming condition; and
transmitting, from the WiFi controller toward a mobility management entity (MME) configured to manage the service provider CBSD nodes, a message identifying UE associated with the CBSD jamming condition and configured to cause the MME to provide respective UE tracking area information to a Spectrum Access System (SAS) managing the service provider CBSD node to enable the SAS to mitigate the respective CBSD node jamming condition.
2. The method of claim 1 , wherein the SAS is configured to mitigate a respective CBSD node jamming condition by causing the MME to migrate UE associated with the CBSD jamming condition to a different service provider CBSD node.
3. The method of claim 1 , wherein the SAS is configured to mitigate a respective CBSD node jamming condition by causing the MME to migrate other UE associated with the CBSD jamming condition to a different service provider CBSD node.
4. The method of claim 1 , wherein the SAS is configured to mitigate a respective CBSD node jamming condition by:
identifying one or more service provider CBSD nodes having locations associated with respective UE tracking area information; and
causing the MME to migrate at least a portion of the UE associated with the CBSD jamming condition to a different service provider CBSD node.
5. The method of claim 2 , wherein the WiFi controller initiates a migration of UE by transmitting the international mobile subscriber identifier (IMSI) value to a mobility management entity (MME) of a 4G mobile network.
6. The method of claim 3 , wherein the WiFi controller initiates a migration of UE by transmitting the IMSI value to a mobility management entity (MME) of a 4G mobile network.
7. The method of claim 1 , wherein the potential jamming condition comprises an indication of a failure of UE to connect or reconnect to the CBSD node after a threshold number of attempts.
8. The method of claim 7 , wherein the potential jamming condition is stored within a Jamming Information (JI) field of at least some of the UE WiFi frames.
9. The method of claim 8 , wherein the JI field is included within a payload portion of a WiFi frame.
10. The method of claim 8 , wherein the JI field is included within a reserved frame type or subtype of a WiFi frame.
11. The method of claim 1 , wherein each UE is configured to preferentially connect to an available WAP in response to entering a mobile network idle state.
12. The method of claim 1 , wherein the MME provides respective UE tracking area information to the SAS only after determining that a jamming condition exists at a CBSD node as indicated by connection failure of at least a threshold amount of UE at the CBSD node.
13. The method of claim 1 , wherein the MME provides respective UE tracking area information to the SAS only after determining that a jamming condition exists at a CBSD node as indicated by no UE currently being connected to the CBSD node.
14. The method of claim 1 , wherein the MME provides respective UE tracking area information to the SAS only after determining that a jamming condition exists at a CBSD node as indicated by connection failure of at least a threshold amount of UE at the CBSD node and no UE currently being connected to the CBSD node.
15. A system for managing service provider network nodes in a converged network, the nodes comprising Citizens Broadband Radio Service Devices (CBSDs) configured for providing network services of the service provider to user equipment (UE) connected thereto, the system comprising:
a WiFi controller configured to manage a plurality of service provider wireless access points (WAPs) providing network services of the service provider to UE connected thereto;
the WiFi controller, in response to receiving WiFi frames indicative of a CBSD jamming condition, transmitting toward a mobility management entity (MME) configured to manage the service provider CBSD nodes a message identifying UE associated with the CBSD jamming condition and configured to cause the MME to provide respective UE tracking area information to a Spectrum Access System (SAS) managing the service provider CBSD node to enable the SAS to mitigate the respective CBSD node jamming condition.
16. A tangible and non-transient computer readable storage medium storing instructions which, when executed by a computer, adapt the operation of the computer to provide a method for managing service provider network nodes, the nodes comprising Citizens Broadband Radio Service Devices (CBSDs) configured for providing network services of the service provider to user equipment (UE) connected thereto, the method comprising:
receiving, at a WiFi controller configured to manage a plurality of service provider wireless access points (WAPs) providing network services of the service provider to UE connected thereto, WiFi frames from UE including WiFi frames indicative of a CBSD jamming condition; and
transmitting, from the WiFi controller toward a mobility management entity (MME) configured to manage the service provider CBSD nodes, a message identifying UE associated with the CBSD jamming condition and configured to cause the MME to provide respective UE tracking area information to a Spectrum Access System (SAS) managing the service provider CBSD node to enable the SAS to mitigate the respective CBSD node jamming condition.
